    If you notice the structure of error handling in bpel, the following user guide will help you. In a SOA BPEL, it can contain call actions that also call external services. If these external services are not available, remote access/connection errors may occur. If you inject catchall into your final BPEL in the main scope, then the catchall stream will probably run automatically even if these errors occur.

    This chapter describes how you can use error handling in almost any BPEL process. Error handling provides a BPEL processing service component that handles error messages or other omissions returned from web services to the outside, and also generates error messages related to business errors or executionm. This chapter also describes how to apply error handling to platform crash errors and perform custom actions handled in the error policy file.

    12.1 Introduction To Handler Charge

    Error handlers mark how the housekeeping aspect of BPEL processes responds when web services return investigations that are not normally required (for example, return an error element instead of a number). An example of an error handler is when a web service normally returns a credit report number, but instead returns the corresponding negative credit report.

    In fig. Figure 12-1 shows an example failure handler that sets the credit score aspect to -1000.

    The code segment in Example 12-1 defines an error handler for this operation in the BPEL file:

    The

    The faultHandlers tag contains the error handling code. In the error handler, always b There is a catch action that sets the full name of the error and a variable, and this special copy operator that sets the main variable creditRating to -1000 .

    If you select n built-in services for the BPEL Process Options component, determine the possible errors that can be returned and set up an error handler for each.

    12.2 Introduction To BPEL Standard Errors

    This category defines standard errors in BPEL 1.1 and BPEL 2.0.

    12.2.1 BPEL 1.1 Standard Error

    This part defines BPEL standard errors from version 1.1. Unless otherwise noted below, the Business Process Execution For Language Web Services specification typically defines the following namespace query errors for http://schemas.xmlsoap.org/ws/2003/03/business -process/ :

  • bindingFault (BPEL extension failures onlyin http://schemas.oracle.com/bpel/extension)

    defined

  • conflicting receipt

  • error handling framework in bpel

    conflicting request

  • Correlation Violation

  • force termination

  • wrong answer

  • attach to error

  • incompatible assignment error

  • remoteFault (BPEL extension error in list http://schemas.oracle.com/bpel/extension)

  • repetition compensation

  • Selection error

  • variable not initialized

  • Untyped, meaning they don’t refer to messageTypes

  • Not related to WSDL (Web Services Description Language) message

  • Caught without error variable:

  • 12.2.2 BPEL 2.0 Standard Error

    The following article describes the standard errors defined in the WS-BPEL specification. All standard task names follow the core WS-BPEL namespace.

  • ambiguous getting

  • completionConditionFailure

  • conflicting receipt

  • conflicting request

  • Correlation Violation

  • How do I create a fault policy on BPEL?

    To create an error rules file, right-click Highlight and select Create in Gallery. Select the Faults option under SOA Layer and select Fault Policy Document to create a new fault policy file. You can change the named default error policy “policy1” to any label according to your naming standards.

    invalidBranchCondition

  • invalid expression value

  • invalid variables

  • attach to error

  • incompatible assignment error

  • missing response

  • no request

  • ScopeInitializationFailure

  • Selection error

  • subLanguageExecutionFault

  • partner role not initialized

  • variable not initialized

  • unsupported link

  • xsltInvalidSource

  • error handling framework in bpel

    xsltStylesheetNotFound

  • 12.2.2.1 Error handling order of precedence in BPEL 2.0

    In BPEL 2.0, the priority for catching errors thrown without the need for associated data is:

  • If there is currently a capture action with a single matching faultName value that does not actually specify the faultVariable attribute, a dilemma is sent to the specified behavior action.

  • Otherwise,if there is a special catchAll action, the error is usually sent to the catchAll error handler.

  • Otherwise, the error is handled by the default error handler.

  • In BPEL 2.0, the order of precedence for finding bugs with the corresponding data thrown into the air is as follows:

  • Frankly, if there is a catch action with an actually matching faultName value that does anything less than specifying a faultVariable attribute, the attribute is passed to the specified action. sent.

  • If the error data is a WSDL type message that contains:

  • The message contains the range defined by the element.

  • The activity hook is available with an associated faultName value that is of any faultVariable type, including a faultElement-QName associated with the most QName of the runtime element saves data for each WSDL lesson.

  • The error is then dispatched to the actually identified catch action, initializing the faultVariable to a value containing the one-part element.

  • Otherwisetea if there is a good capture activity with harmonization
