Re-submit BPEL instances from BAM

Ramkumar Menon
Director, Product Strategy

Here is what I did for re-initiating BPEL instances from BAM.

a) While defining the BAM sensor action, passed in the conversation Id of the instance [obtained using the xpath function ora:getConversationId()]
b) Developed a Servlet that takes in a conversationId as a request parameter and initiates a new BPEL instance with the same input message.
c) Created a table with an Action button that invokes the Servlet [using Open URL action] and passes in the conversationId.. The table contains columns that contain key identifiers for the transaction. [e.g. POId etc]
d) At runtime, users select the rows in the table based on the identifiers and click on the action button - this will re-initiate the BPEL instance.

Here is a snippet of code that does the trick.

        IBPELDomainHandle domain = null;
        Locator locator = null;
        String convId = request.getParameter("convId");

        Properties p = new Properties();
        java.net.URL url = ClassLoader.getSystemResource("context.properties");
        p.load(url.openStream());

        locator = new Locator("default","weblogic",p);
        domain = locator.lookupDomain();
        WhereCondition wc = new WhereCondition("conv_id=?");
        wc.setString(1,convId);
        IInvokeMetaData[] invMetadataArr = locator.listInvokeMessages(wc);
        IInvokeMetaData invMetadata = invMetadataArr[0];
        String messageGuid = invMetadata.getMessageGUID();
        domain.recoverInvokeMessages(new String[]{messageGuid});

    Hi Ram,
    Many thanks for your post on the customtasks.jar(Customizing any BPEL Project Artifact using customizeDocument) , this has helped us in resolving code issues, however I need to understand the following
    Is this customtasks.jar an Open Source Code?
    Does it have any IPR(Intellectual Properiety Rights) issues ?
    Can this be submitted as a part of Code Delivery to customer ?
    Can you please let me know any other link (preferably Oracle /SUN Link) from where this jar can be downloaded.
    In case you need to discuss anything , please give me call my contact details are mentioned below.
    Thanks and Regards
    Amar

    Hi Ram ,
    Our client also has the similar requirement .
    We have two asyncronous bpel processes call.
    Bpel 1 Calls Bpel 2 (both are asyncronous process).
    now while doing so BPel 2 fails.Now our smart Bpel 2 before termination calls Errorhandle bpel process to tell user about error through mail.
    Now once they do action on the xml we want to resubmitt same message through Bpel 2 via code you have provided in Errorhandle bpel .
    After seeing your code I realised that we can get Instance mesasge and then resubmitt bpel task once again.
    But I guess your code is incomplete Can you assist me doing changes .
    Than x,
    Rashmi.
