Declaring Extensions

Declaring Extensions

An extension declaration allows you to add a new construct to a BPEL process. Process Developer ignores it, since it can not understand it.
You can extend the definition of the BPEL language by declaring an extension. An extension declaration allows you to add constructs such as a new activity type or new processing instructions that are outside of the WS-BPEL 2.0 specification.
Process Developer and the Process Server use extensions. The Process Developer extensions are:
  • Query handling for automatically creating XPath for Copy To targets and for disabling the bpel:selectionFailure fault. (See
    Using the Process Developer Create XPath Extension
    and
    Using the Process Developer Disable Selection Failure Fault Extension
    .)
  • Suspend, break, and continue activities. (See
    Overview of BPEL Activities
    .)
  • Process level compensation/termination .(See
    Creating a BPEL Process as a Service for Another BPEL Process
    .)
  • Implicit scope variables.
  • Loopback links. (See
    Using Links
    .)
When you use one of these extensions, the extension namespace is automatically added to the Outline view. However, you can add the extension namespace manually before you use the extension, if desired.
To add your own extension definition
:
  1. From the Outline view, select Extensions, and right-click to select
    Add > Declaration > Extension
    .
  2. In the
    Extension Definition
    dialog, select User Defined Extension Namespace.
  3. Type in a namespace referencing your BPEL extension.
  4. Check
    Must understand
    if required. Note that when this is selected and you use the extension in your process, Process Developer reports an error when you save the process. The process cannot be simulated or deployed. If you do not select Must understand, your extensions are ignored by the Process Server.
