    Hi Guys
    Any idea if you can tell me how to invoke BPEL process from JAVA API ?
    What to do in BPEL process manager to achieve that?

  • Invoking bpel process from java in oracle soa/bpm 11g

    Hi,
    We have some java code to invoke bpel process in oracle BPM 10g following the instructions in http://download-east.oracle.com/docs/cd/B14099_19/integrate.1012/b14448/invoke.htm.
    Basically the steps are:
    1) get a Locator (com.oracle.bpel.client.Locator)
    2) get IDeliveryService (com.oracle.bpel.client.delivery.IDeliveryService) reference from locator
    3) call IDeliveryService method request or post with input message and get the response back.
    Recently we want to migrated from oracle bpm 10g to oracle soa/bpm 11g. But I can not find the similar API in 11g. It seems now some adapter/binding need to be added in exposed service lane in soa composite view, for example, ADF-BC, direct binding etc, in order to allow java to invoke a bpel process. Here are two very useful links from Edwin about the detail how this is implemented.
    http://biemond.blogspot.com/2009/11/invoking-soa-suite-11g-service-from.html
    http://biemond.blogspot.com/2009/11/calling-soa-suite-direct-binding.html?showComment=1285198033913#comment-c1055322845511794252
    My question is:
    1) what are the choices and the official/best way to invoke a bpel process in oracle soa/bpm 11g from java?
    2) does user need to add an adapter/binding in exposed service lane in order to let the bpel service be called in java?
    3) what is the real difference between a bpm application and soa application in 11g?
    I will really appreciate any expert's opinion.
    Thanks,
    Bin

    Thanks for your reply and confirmation, really appreciate it.
    Yes, I found the difference of the invoking process API and was able to invoke bpel process using direct and ADF-BC binding by following Edwin's blog. But I have not found any official reference to compare this API difference between 10g and 11g ( I will mark this question as answered if anyone can find an official source from oracle, need to prove it to the team). The API to work with human task workflow seems pretty much the same between 10g and 11g.

    For 11g BPM please look at this post. Re: Getting while running the BPEL process from java
    It references an ATeam example app that can start processes from a web client. But the Java APIs are described too.

  • Invoking bpm process from outside

    Hi,
    Currently, i can invoke a BPM Process web service from the WS Navigator. The next step is, how can i invoke this service from outside? I'm using SOAP-UI and i download the wsdl file from the service registry.
    It seems, the wsdl is not in a standard form. Could someone share a light here?
    Thanks,
    Aries

    Hi Aries,
    Could you please elaborate on your use case? Did you publish your process exposed as a Web Service in the ESR?
    You mentioned that your wsdl is not standard conform. Can you please copy it in this thread?
    From a tool perspective, the process is exposed using the web service interface provided in the start event. If the exposed process is not standard conform, you could compare the wsdl provided to the Process Composer to the one dowloaded from the WS nagvigator and the one downloaded from ESR.
    Best regards,
    David

  • Invoking BPEL process from Java servlet with org.w3c.dom.Element as payload

    Hello,
    I'm trying to initiate a BPEL process from my servlet running under Tomcat. When I create the NormalizedMessage passing the XML as a String everything works fine. But if I use an org.w3c.domElement the BPEL server doesn't react at all (even on DEBUG log level there are no outputs).
    This works:
    NormalizedMessage message = new NormalizedMessage();
    message.addPart("payload", "<foo></foo>");
    This doesn't work:
    org.w3c.dom.Element elem;

    NormalizedMessage message = new NormalizedMessage();
    Element elem = xmlDocument.createElement("foo");

    Is there a known problem with payloads using Element or did I get something completely wrong? Thanks in advance,

    Could you please run obversion.bat and let us know what version of the engine you are running? If timezone allows and you have the availability, I would like to try to broker a quick 15-minute web conference with a member of our dev team to look at this problem and provide a more detailed answer. What is your time difference with San Francisco (PST)?

    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.

  • Error Invoking a BPEL process from JAVA

    Dear colleagues,
    I'm facing a error at execution time when I'm invoking a BPEL process from java. My BPEL process is in a different server than my application. BPEL is running in SOA SUITE 10.1.3.1 and my JAVA application so far is in the embebed OC4J of my Jdveloper 10.1.3.3. I've seen different post with a similiar problem, but there wasn't never a solution!. Here you have the code following by the error:
    ***************** SOURCE **************************************
    Locator locator = new Locator("default", "bpel");
    IDeliveryService deliveryService =

    System.out.println(deliveryService.SERVICE_NAME);
    System.out.println(deliveryService.LOCAL_SERVICE_NAME);
    NormalizedMessage nm = new NormalizedMessage();
    nm.addPart("payload", xml );
    NormalizedMessage res =
    deliveryService.request("LOAD_DB_5", "process", nm);

    Hi
    You are trying to create a locator object with default values which does not work at all times.Use Locator("default",prop) where prop is a properties object and set the values according to your environment.
    The following properties values must be set
    Properties props=new Properties();
    props.setProperty("orabpel.platform","ias_10g");
    props.setProperty("java.naming.factory.initial","com.evermind.server.rmi.RMIInitialContextFactory");
    props.setProperty("java.naming.provider.url", "url value");
    props.setProperty("java.naming.security.principal","domain user name");
    props.setProperty("java.naming.security.credentials","password");
    props.setProperty("dedicated.rmicontext", "true");

  • Invoking asynchronous BPEL process from java ui

    Hi,
    I am invoking an asynchronous BPEL process from java ui.
    I read somewhere that i can obtain an instance handler uing the lookupInstance() method of class Locator using the conversation id provided by the class NormalizedMessage.
    My code looks like this
    // Connect to Oracle BPEL server
    Locator locator = new Locator("default","bpel");
    IDeliveryService deliveryService = (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
    // Construct a normalized message and send to Oracle BPEL Process Manager
    NormalizedMessage nm = new NormalizedMessage();
    nm.addPart("payload", xml);
    // Initiate the BPEL process
    deliveryService.post("MyLoanFlow", "initiate", nm);
    //Obtain the instance handler
    IInstanceHandle handle = locator.lookupInstance(NormalizedMessage.CONVERSATION_ID);
    But this is giving the error - can not find any instance with conversation id 'conversationId'.
    Also, if i try to obtain a list of instance handles associated with a process , it does not contain the most recently created instance
    IBPELProcessHandle ph = locator.lookupProcess("MyLoanFlow");
    IInstanceHandle[] iHandler = ph.listInstances();
    out.println(iHandler.length + "<br>");
    if i invoke the process for the first time the output is 0.
    can you please help me. it is urgent.

    Hi Sudipto,
    Regarding your second question,
    deliveryService.post("MyLoanFlow", "initiate", nm);
    IBPELProcessHandle ph = locator.lookupProcess("MyLoanFlow");
    IInstanceHandle[] iHandler = ph.listInstances();
    out.println(iHandler.length + "<br>");
    ---- returns 0 ---
    This is because MyLoanFlow is an asynchronous process in your case. So the control is returned to your java block immediately after the request for a new instance is posted. And your second line of code(querying for the list of instances) is executed even before the instance is created on the server side. You can verify this in two ways:
    1. try creating an instance of a synchronous process using IDeliveryService.request - this will always result in the increment since the current thread is blocked till the new instance is created.
    2. for your case, you can try
    Thread.currentThread().sleep(500); - just allow the server some time for completing the instance before you query it for the list of instances..
    and wrt question 1,
    //Obtain the instance handler
    IInstanceHandle handle = locator.lookupInstance(NormalizedMessage.CONVERSATION_ID);
    But this is giving the error - can not find any instance with conversation id 'conversationId'.
    For setting the conversationId, you could do so by including the following inside your .bpel file
    <bpelx:exec name="test-setConversationId" language="java" version="1.4">
    <![CDATA[
    setConversationId("conversationId");
    ]]>
    </bpelx:exec>
    The code:
    IInstanceHandle ins = locator.lookupInstanceByConversationId(NormalizedMessage.CONVERSATION_ID);
    should fetch you the required instance in this case.
    HTH,

  • DOS 11g SOA have the Locator API's - How to Invoke a BPEL process from Java

    In BPEL 10.1.3.1, a java client could use the "Locator" API's to look up a BPEL service and invoke it directly from Java,
    Is that still present in SOA 11g ? Or is there another way to look up the BPEL process ...
    Here's an example of the 10g BPEL Service locator facilities :
    Get the BPEL service locator. This is retrieved as follows:
    loc = new Locator(domain, domainPassword);
    The initial installation BPEL domain is "domain" and the initial password is "bpel". We then use the locator to get the delivery service. We could also use the locator to retrieve the workflow service.
    IDeliveryService svc = (IDeliveryService)loc.lookupService(IDeliveryService.SERVICE_NAME);
    Now we have the delivery service we can "deliver" requests to the BPEL process. To do this we first need to create a new message.
    NormalizedMessage msg = new NormalizedMessage();
    String content = "<SyncHelloWorldProcessRequest xmlns=\"http://antony.blog/SyncHelloWorld\">"+
    "<input>"+
    name+
    "</input>"+
    "</SyncHelloWorldProcessRequest>";
    msg.addPart(msgPart, content);

    Eric, when I select the BPEL wsdl file in "Create Web Service Data Control" wizard, immediately I am getting the error. When I click 'OK', the 'Service' dropdown is disabled and blank in the wizard.
    Thanks for pointing to the sample application URL. But it is built in jdev 10g. Can I migrate it to 11g?
    Thanks both of you!

    Did you ever find a solution to your problem?
    My situation is that I'm running a process that grabs data from a salesforce.com web service and dumps some of the data back into my local database. The process croaks after processing 850 or so records. I have also increased my PermSize memory to 512M.
    Any ideas why all of a sudden after processing that many records it would stop working?
    Thanks,
    Adam
