Invoking a BPEL process using user_request

Hi All,
I've designed a BPEL process and verifed it works fine. I would like to initiate this process via the 'Lock' event in OCS. Can this be done using user_request? If so what are the steps involved to set this up?
I appreciate your time and help.
Thanks!

Sancho,
Thanks for the prompt reply. We trying to automate the following process:-
1. The user select multiple documents from a folder in a library that contains all released documents.
2. He then locks the documents.
3. Selects the locked documents and copies it to a folder in the personal library.
We are trying to lock and copy the documents as a 1 step process, because its difficult for the users to select all of the documents locked earlier and then copy it the personal library.
We are trying to take the folder name as the user parameter, when the files are locked, so that the process and create the lock the files, create the folder and copy the files in this folder.
Thanks again for your time and help.

    Have got the same problem. Scenario at my end is little different though.
    I am trying to invoke a BPEL process from an ESB Service.
    I am trying to look into it..
    However, would be grateful, if someone can give some insight into this since many are running into this issue without being able to fix.

  • Invoking deployed bpel process using WLST

    Hi All,
    Am new to WLST. So please tolerate with me if i am asking the obvious
    I read through the forums and have successfully deployed a BPEL process using WLST as given below
    ant -f ant-sca-deploy.xml -DserverURL=http://localhost:8001 -DsarLocation=C:\oracle\Middleware\PS3\Oracle_SOA1\bin\sca_esd9_jca_bpel1.1_ccgd_trn_ob_rev1.jar -Doverwrite=true -Duser=weblogic -Dpassword=welcome1 -DforceDefault=true
    And i have also tried un deploying and it works fine.
    But, the problem is, i want to invoke the deployed BPEL process either by accessing the WSDL URL (http://localhost:8001/soa-infra/services/default/esd9_jca_bpel1.1_ccgd_trn_ob/bpelprocess1_client_ep?WSDL) or by any other means using WLST. I have to send an input to this deployed process.
    I have googled it and have found ways to invoke a web service using JAVA or VBS. But is it possible to do it through WLST?
    Thanks in advance.

  • How to invoke WebService / BPEL process using stubs in Jdeveloper 10g

    HI,
    I created the SyncHelloworld BPEL process as given in tutorial 1.
    Now I created a new project to call this BPEL from Java client.
    I used the JDeveloper to create the stub/skeleton using the wizard by specifying the WSDL file location.I also created the main method by selecting the checkbox in the wizard.
    Now I want to invoke this SyncHelloWorld. There is a method called process. It expects a Element as input and returns a Vector.
    Now how do i pass a string ( which the SyncHelloWorld process expects ) from the main method and call the process method.
    Has anyone tried this ? I am new to this technology.
    What I am trying to do is trying to invoke a webservice. I have the WSDL file and its location. What all I need to do is pass the required parameters as an Element and get the output as Vector.
    Any help would be highly appreciated.
    Thanks,
    Debojyoty

    Hi,
    Did you tried it from the generic soap tester online from that site, or did you download some client testtool ?
    myserver:9700 cant be reached from the site where you're trying to test it.
    this is an internal host.
    or if it can be reached from outside..maybe some firewall problem?

  • Invoking a BPEL Process from Java Class

    Regards

    Hi -
    A few things that you may want to try to troubleshoot this issue:
    1) Run our sample of calling a BPEL process from Axis, located in:
    C:\orabpel\samples\interop\axis\AXISCallingSyncBPEL
    2) Run your client through a TCP tunnel to see the specific SOAP request message that is being sent to the BPEL process and the SOAP response that is being generated. This should help you determine which side of the communication is causing the problem, as well as to rule out proxy server or other issues that are very common problems for this situation.

  • Issue in invoking the BPEL process from Oracle using a SOAP Request

    Hi,
    We are facing an issue while invoking a deployed Bpel Process from Oracle Applications 11.5.10..
    Using a concurrent program( Unix / Host program ) we are passing the input variables required for the Bpel process in the ProcessRequest tags and forming this as a SOAP message payload.
    Then trying to invoke the deployed bpel process using the end point location using HTTP POST..but nothing is happening..
    The bpel process is not getting invoked when i look at the Console and also checked for the Manual Recovery queue..it's not stuck there as well..
    Have set the Transfer Time Out to 25 minutes using UTL_HTTP.SET_TRANSFER_TIMEOUT(1500);
    Could someone please help us as soon as possible with this ..as this is critical and we are stuck at the moment.
    The logic is mentioned below :
    UTL_HTTP.SET_TRANSFER_TIMEOUT(1500);
    UTL_HTTP.SET_DETAILED_EXCP_SUPPORT(ENABLE=>TRUE);

  • Invoke BPEL process using a java client - NullPointer Exception

    Hi, We are trying to call a BPEL process using a java client from our Web Application. For some reason the BPEL engine just logs a NullPointerException and exits.
    The same SOAP request when through SOAP UI tool works great.
    Any help in resolving this is highly appreciated!

    Hi,
    Please ensure that you include the SOAP Header "SOAPAction" in your request. Most importantly, the value for that should be enclosed within double quotes.
    For eg;
    req.setRequestHeader("SOAPAction", '"process"');

    Have got the same problem. Scenario at my end is little different though.
    I am trying to invoke a BPEL process from an ESB Service.
    I am trying to look into it..
    However, would be grateful, if someone can give some insight into this since many are running into this issue without being able to fix.

  • Issue while invoking a BPEL process

    Hi
    We are invoking a BPEL prcs from ESB project.The ESB project has a Oracle application adapter to read from a queue and a external soap service to invoke a BPEL process.
    The Oracle application adapter is working fine as it is pulling data from the queue successfully and after that the BPEL process is invoked using the soap external service.
    Now the interesting part is that the process when newly deployed (v 1.0) works fine but after sometime ESB fails to invoke the BPEL service. We then again redeploy the BPEL prcs(v 1.0) and evrything works fine but only for few instances....... So evry time we are having to redeploy the BPEL prcs when ESB fails to invoke the BPEL prcs
    The error that we get at the ESB console is :
    An unhandled exception has been thrown in the ESB system. The exception reported is: "org.collaxa.thirdparty.apache.wsif.WSIFException: exception on JaxRpc invoke:
    HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message transmission fa

    at com.collaxa.cube.ws.wsif.providers.oc4j.jaxrpc.WSIFOperation_JaxRpc.invokeOperation(WSIFOperation_JaxRpc.java:1720)
    and in the WSM gateway error is :

    Please help!!
    Thanks

    Hi
    I made a mistake.... I copied the wrong error message from the ESB console ..... The response code is 500 and not 401.......
    Here is the message at ESB console :
    An unhandled exception has been thrown in the ESB system. The exception reported is: "org.collaxa.thirdparty.apache.wsif.WSIFException: exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message transmission failure, response code: 500 at com.collaxa.cube.ws.wsif.providers.oc4j.jaxrpc.WSIFOperation_JaxRpc.invokeOperation(WSIFOperation_JaxRpc.java:1720) at com.collaxa.cube.ws.wsif.providers.oc4j.jaxrpc.WSIFOperation_JaxRpc.invokeRequestResponseOperation(WSIFOperation_JaxRpc.java:1466) at

    What should I do remove this problem?

    Your problem sounds like many RMI problems answered in this forum in the past, especially if the java client is not on the same container as the bpel engine.
    Usually solved with setting some environment properties like dedicated.rmicontext=true etc.
    Please search the forum history.
