Using the FTP Binding Component in a Project

In this tutorial, you will create a simple BPEL Module project called SendInventory and a Composite Application project called SendInventoryCompAppl. Here, you create two WSDL Documents and design a BPEL Process. Then, deploy the project. You will learn the method to transfer the file from the local directory to the FTP Server through FTP and FILE Binding Component.

What You Need to Know

These topics provide information you need to know before using the FTP Binding Component.

What You Need to Do

These topics provide instructions on the following.

The FTP Binding Component (referred as FTP BC) is a binding component implementation in compliance with JBI Specification 1.0.

FTP BC uses the FTP protocol to transport messages. This helps define the services using WSDL and bind them to FTP as the underlying message transport protocol. For example, in a JBI environment, the Services Engine (SE) can orchestrate the services consumption and provision.

The FTP BC implements all required using JBI specification so that it can be deployed and executed in any JBI compliant target environment.

This implementation also uses a NetBeans module as the design-time component to facilitate the process of service definition and binding. The NetBeans module makes WSDL authoring and FTP binding convenient in the NetBeans IDE.

This tutorial illustrates the following aspects of the FTP Binding Component.

  1. Create a SOA project.

  2. Add WSDL documents to your project.

  3. Use the Partner view of the WSDL editor to add the messages, partner link type, port type, and operation.

  4. Create a Composite Application project.

  5. Use the Composite Application (Service Assembly) editor to modify the project configuration.

Read the tutorial thoroughly before installing and executing the Binding Component.

Software Needed for the Tutorial

FTP BC assumes that the following are configured on the system:

  5. Create a Composite Application project.

  6. Add the BPEL Module project (*.jar) as a JBI Module to the Composite Application project.

  7. Build the Composite Application project. Ensure that the Application Server is started.

  8. Deploy the Composite Application project to the Application Server.

  9. Check the Output.

The illustration explains the process of creating a project in FTP Binding Component.

The FTP server is used as a communication hub for a manufacturing supply chain. The Manufacturer sends an XML file with inventory levels of multiple products (using a Business Process that reads a local file with File-BC and places it in the FTP server using FTP-BC). Supplier picks up the XML file and updates inventory levels (using a Business Process that retrieves the file from the FTP server using FILE-BC). The Manufacturer Business Process uses simulated data created in-line and the supplier prints inventory levels on ftpout.

The GlassFish ESB installer is available at the following location:

    Tip –

    Deploying an application to the GlassFish Application Server starts GlassFish automatically. Thus, you do not have to manually start the application server.


The Java Business Integration (JBI) runtime environment provides the runtime capability for SOA tools in the IDE. The JBI runtime environment includes several components that interact using a services model. This model is based on Web Services Description Language (WSDL) 2.0. Components that supply or consume services within the JBI environment are referred to as Service Engines. One of the components is the BPEL Service Engine that provides services for executing business processes. Components that provide access to services that are external to the JBI environment are called Binding Components (BC).

The JBI components are installed as part of the GlassFish application server. This server is packaged with the NetBeans IDE.

To View the Installed or Deployed JBI Components

  1. Click the Services tab. Expand the GlassFish V2 node. Expand the JBI node.

    Note –

    When creating or editing a WSDL file, you may be prompted to select a binding type and a binding subtype. A binding contains protocol and data format information for the operations and messages of a port type. If you select the FTP binding type, then you must select one of the following binding subtypes. Both subtypes provide basic FTP functionality, such as a directory from which to read or write files, filename pattern matching, and message correlation.

    • FTP Message. Select this binding subtype if you plan to rely on default values.

    • FTP Transport. Select this binding subtype if you want to add customization such as specifying custom directories on the FTP server and specifying pre-transfer and post-transfer operations.


  5. Choose the Binding — FTP from the drop-down list.

  6. Choose any one of the following Types from the drop-down list.

    • Poll Request Message: Choose this scenario when the FTP BC polls for request message(s) from a dedicated sub-directory (inbox). In this example, the sub-directory is under the remote FTP directory (message repository) and invokes a JBI service with the message(s).

    • Poll Request Message and Put Response: Choose this scenario when the FTP BC polls for request message(s) from a dedicated sub-directory (inbox). In this example, the sub-directory is under the remote FTP directory (messaging repository) and invokes a JBI service. It puts the response(s) back to a dedicated sub-directory (outbox) under a remote FTP directory (messaging repository).

    • Put Request Message: Choose this scenario when a JBI service invokes FTP BC to put a request message to a dedicated sub-directory (outbox). In this example, the sub-directory is under the remote FTP directory (messaging repository).

    • Put Request Message and Poll Response: Choose this scenario when a JBI service invokes FTP BC to put request message(s) to a dedicated sub-directory (inbox).

Default value: true

FTP Binding Component is bound to either a service consumer or service provider, the interfaces exposed is defined by a WSDL. FTP Binding Component implements a set of FTP Binding Component binding specific extensibility elements so that a service can be defined and bound to a FTP protocol.

The FTP Binding Component supports the following extensibility elements:

  1. Address: Specifies the FTP connectivity element information such as, FTP URL (host, port, login, password), directory listing style, user defined heuristics for directory listing parsing.

  2. Binding: FTP binding element, a marker element indicating a FTP binding. This element does not have attributes.

  3. Operation: FTP operation element is a marker element indicating a FTP operation. This element does not have attributes.

  4. Transfer: FTP transfer element, specifies a message transfer from a sender and receiver perspective. For example, to specify a message transfer for a service request, there is a sender and a receiver involved, the WSDL author specifies:

    1. The target sender sends to: Represented by attribute ftp:sendTo, the target receiver receives from — represented by attribute ftp:receiveFrom. Also, the additional operations performed before a message is sent (PUT) to target or after a message is received (GET) from the target and is called Pre/Post operations.

    2. messageCorrelate: If enabled, a UUID tagging based message correlation scheme will be used to correlate requestresponse of a synchronous service invoking.

  5. Message: FTP message element, specifies a message transfer from a service consumer and/or service provider perspective. The WSDL author can specify:

    1. The message repository represented as attribute ftp:messageRepository. A base directory where all the working directories for a message transfer are created, such as,

      1. inbox : Is used for posting request (by consumer) and polling request (by provider)

      2. instage : Is used for staging request

      3. outbox : Is used for posting response (by provider) and polling response (by consumer)

      4. outstage : Is used for staging response

    2. messageCorrelate : If enabled, a UUID tagging based message correlation scheme will be used to correlate request-response of a synchronous service invoking.


Note –

Application Variable is a tabular data consisting of one or more name value pairs. On the other hand, WSDL authors are allowed to include references of these 'tokens' in the attributes values of FTP Binding Component extensibility elements in their WSDL, the references are resolved at deployment time.

Application variables are categorized into the following types:

  1. STRING

  2. BOOLEAN

  3. NUMBER

  4. PASSWORD

    • Poll: Choose this type for a scenario when the File BC polls for message(s) from a file directory and invokes a JBI service with the message(s).

    • Poll and Write Back Reply: Choose this type for a scenario when the File BC polls for message(s) from a file directory, invokes a JBI service and writes the response(s) back to the directory.

    • Write: Choose this type for a scenario when a JBI service invokes File BC to write a message to a file directory.

    • On Demand Read: Choose this type for a scenario when a JBI service invokes File BC to read a specific message from a file directory.

  7. Select Type — Poll from the drop-down list.

  8. Click Next.

    This opens New WSDL Document — Request Configuration wizard.

  9. Enter the following fields:

    1. File Name* (pattern): Defines the file name relative to the specified directory.

      If fileNameIsPattern is not true, this attribute specifies an actual file name. Otherwise, this attribute specifies a pattern marker used for filtering input files from the directory, or a file name format to write to the directory. The supported patterns are:

      • %d: Denotes an unique number for input and an one-up sequence number for output file names.

      • %u: Denotes a wild card match for input and an UUID for output file names.

      • %t: Denotes an unique timestamp for both input and output file names. The expected date format is yyyymmdd-HH-mm-ss-SSS. For input file names, the -HH-mm-ss-SSS part may be omitted to guarantee unique names.

      • %{ }: Denotes an integer number in the input file name or a one up sequence number persisted in a sequence file if it is for a output file.

      For example, inventory%d.xml

    2. Polling Directory*: Defines the directory name where the WSDL provisioner reads the input files and where the client writes the files.

The BPEL Designer has a built-in BPEL code validation functionality that helps create well-formed, valid and standard-compliant code. The code is checked for errors and the user is notified, if validation fails.

To Invoke Explicit Validation

Perform any one of the following to invoke explicit validation.

  1. In the Source view, right-click the source to invoke the pop-up menu. Choose Validate XML (Alt-Shift-F9).

  2. In the Design view, click the Validate XML button (Alt-Shift-F9) on the Editor toolbar.

The validation errors are notified to the user on the Output window, Design window and the Navigator.

The Design View

The Design view shows the results of both real-time and explicit validation in callout windows on the diagram and the error stripe.

In the illustration,


Note –

A red cross next to an element means that the element has not passed validation and the output contains errors.

A yellow triangle with an exclamation mark means that the element has not passed validation and the output contains warnings.

A red cross in the Design view means there are both errors and warnings.


If you click the cross or the triangle, a callout window appears with a list of errors and warnings.

The callout window includes messages related to validation in accordance with all the criteria listed above. Messages related to the real-time validation are constantly updated.

In the Design view an error stripe displays validation results. An error stripe is a strip next to the right of the scroll bar that contains red marks if some elements have not passed validation. The error stripe represents the entire diagram and not just the portion that is on display. You can immediately see if your BPEL process contains errors without having to scroll through the entire diagram. You can click a red mark to jump to the element that is causing problems. The small square in the error stripe is green, if no errors are detected.

Add the JBI module to the BPEL Module project before deploying the Composite Application. Deploying the project makes the service assembly available to the application server, thus allowing its service units to execute.

To Create a Composite Application

  1. Choose File —> New Project from the main menu.

    This opens the New Project wizard.

  2. Select the SOA node from the Categories list.

  3. Select the Composite Application node from the Projects list.

  4. Click Next.

  5. Type the Project Name in the Project Name field.

    For example, SendInventoryCompAppl

  6. Click Finish.

    The Projects window now contains a project node for a Composite Application project called SendInventoryCompAppl.

    This action displays a message in the Output console.

  7. Right-click either the Composite Application Project node or expand the node. Select JBI Modules.

    For example, SendInventoryCompAppl

  8. Select Add JBI Module.

  9. Select the Project. Click Add Project JAR Files.

    For example, SendInventory

    The Project JAR Files is build/SEDeployment.jar.

    The SendInvetory.jar is added to the project.

  10. Click Save All.

  11. Right-click the Composite Application project node. Select Clean and Build.

    For example, SendInventoryCompAppl

    This action displays a message in the Output console:


    BUILD SUCCESSFUL (total time: 1 seconds)
  12. Click Save All.

Deploying the Composite Application

File Binding Component is used to pick messages from a local directory.

FTP Binding Component is used to transport messages between the consumer and the provider using FTP.

To Deploy the Composite Application

  1. Create a folder and save the file in the local directory.

    For example, c:/temp and inventory%d.xml

    Here, foldername is c:/temp and the filename is inventory%d.xml.

  2. Create a folder on the FTP Server.

    For example, book_updates

    The folder is empty before deployment.

  3. Select the project node in the Projects window.

    For example, SendInventoryCompAppl

  4. Right-click and choose Deploy.

    After deployment of the project, the following message is displayed in the Output window:


    BUILD SUCCESSFUL (total time: 18 seconds)
  5. Check for the folder in the local directory.

    Two folders are created under SendInventoryCompAppl_FileInboundService_fileTrig-45609436–4:

    1. archive

    2. filebc-in processing

  6. Check the folders on the FTP Server.

    After deployment, inbox and instage folders are created.

  7. Double-click the folder /inbox to check the output.

    The message routing starts with the consumer invoking a service (INVOKE in BPEL script). On the other side of the NMR, FTP BC OutboundProcessor accepts the request message, de-normalizes the message and labels the message body (which is the payload to a FTP file) with name as req.

This topic explains the functional behavior of various binding types.

  1. Poll Request Message and Put Response

    1. Poll Request

      • Message Name Prefix: Prefix for inbound (IB) message name.

      • Poll Interval in milli-seconds: Polling interval in milliseconds when message is polled from a remote target.

    2. Put Response

      Message Name Prefix: Prefix for outbound (OB) message name.

  2. Put Request Message and Poll Response

    1. Put Request

      Message Name Prefix: Prefix for outbound (OB) message name.

    2. Poll Response

      • Message Name Prefix: Prefix for inbound (IB) message name.

      • Poll Interval in milli-seconds: Polling interval in milliseconds when message is polled from a remote target.

  3. Put Request Message

    Message Name Prefix: Prefix for outbound (OB) message name.

  4. On Demand Get Message

    1. Message Name Prefix: Prefix for inbound (IB) message name.

    2. Enable Archive Polled Message: Indicates if archive is required for processed message. If true, processed message is archived, otherwise, it is removed.

  5. Receive Request

    Poll Request

    1. Receive Source (From): Path pointing to a file on remote FTP server where the transferred data will be read (receiveFrom), the path components could be literals or regular expressions.

    2. Receive Source (From): Has Regular Expressions. Indicates if 'receiveFrom' has regular expressions. When 'receiveFrom' contains regular expressions, these are used as filters to filter out those directory/file entries that match the corresponding regular expressions.

      For example, if 'receiveFromHasRegexs' = FTP_IN_BOX/archive200[1-6]/invoice_[0-1][1-9].bak

      At runtime, FTP BC gets a directory listing from FTP_IN_BOX, iterate through each one of them and finds the first match for regular expression 'archive200[1-6]'.

      For example, archive2001, get a directory listing from FTP_IN_BOX/archive2001, iterate through each one of them and find the first match for regular expression 'invoice_[0-1][1-9].bak', say, invoice_01.bak, now FTP_IN_BOX/archive2001/invoice_01.bak is found as the first match, and it will be used as the resolved value for 'receiveFrom', otherwise, if no match found for regular expression 'invoice_[0-1][1-9].bak', FTP BC will go back to the parent level, and try the next match of 'archive200[1-6]', and repeat the above process until found a path matching all the regular expressions as corresponding path components or no matching path found after exhausted all paths under FTP_IN_BOX.

    3. Pre Receive Operation (Command): Operation performed before receiving starts.

      • NONE - No operation is performed before receiving starts.

      • COPY - Make a copy of the target file (specified by 'receiveFrom') to a file specified by 'preReceiveLocation' before receiving starts.

      • RENAME - Move the target file (specified by 'receiveFrom') to a file specified by 'preReceiveLocation' before receiving starts.

    4. Pre Receive Operation Location: Destination file for operation to be performed before receiving starts.

    5. Pre Receive Location Has Patterns: Indicate if 'preReceiveLocation' contains patterns:, where 'pattern' is a string containing special characters escaped by percentage sign, the following are all the symbols supported:

      1. directory/file name replacement (%p/%f), usually used in pre/post operation's 'receiveFrom'/'sendTo' path.

        For example, when 'sendTo' is my_in_box/invoice.dat, then a pattern like %p_backup/%f.bak will be my_in_box_backup/invoice.dat.bak after expansion.

      2. UUID %u, will be substituted by a UUID value compliant with Java 1.5 UUID.

      3. sequence number reference %0, %1, %2, %3, %4, %5, %6, %7, %8, %9, this symbol will be replaced by the current value of sequence number, which is an integer count that increments after each reference.

      For Java Tiemstamp Patterns, see Table 4.

    6. Post Receive Operation (Command): Operation performed after receiving completes:

      • NONE - no operation performed after receiving completes.
