Invoking JDev bpel process from Eclipse BPEL Process?

Is it possible to invoke a bpel process (with dbadapter) developed in JDev from a bpel process created in Eclipse (Designer)?

I was unsuccessful.
Scenario:
I was trying to invoke jdev bpel process (that had a database adapter to update the database) from Eclipse bpel process (since we do not have adapters in Eclipse designer).
The namespace wasn't known by Eclipse( some schema missing?) and therefore we couldn't compile it.

  • Error while invoking ESB process from a BPEL process

    Hi all
    We have a requirement to call an ESB process from a BPEL process. We are using an adapter wth the ESB's WSDL url. After deploying the BPEL process, the registered ESB is getting called for most values while suddenly some values return the followign error
    *"exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Connection reset"*
    The catch here is, if we re-run the process with the same values again, the ESB is called successfully! How is it possible for a process to error out and run normally for the same inputs ?
    What could be the possible fix for this? I am thankful for any inputs on this.
    Vijay

    Hi Vijay,
    This is a bug and you can refer the metalink note:
    "Applying Patch 7445876 Results in Error "java.lang.NullPointerException". [ID 942575.1]" for reference.
    Also you can refer the following link:

  • Invoking bpel process from another bpel process in same app server

    Hi,
    When I invoke a bpel process from another bpel process in the same oracle AS
    1. Is it a SOAP call or is there any optimization?
    2. If there is some optimization where can I configure this?
    3. Is there any similar optimizations if I invoke a bpel process from a
    java application deployed in the same server? If so can you please provide
    a sample?
    Thanks for your help
    Raj

    By default the BPEL 10.1.2, it will do a local call to the process. It will not execute a SOAP request, no network access is done.
    It can be configured at domain level:
    Parameter: optSoapShortcut (SOAP local optimization)
    Turns on "short-cut" for local SOAP request; local SOAP calls are normally done via an internal call instead of sending a message through the SOAP stack.
    The default behavior for the engine is to optimize all. To disable optimization specify a value other than "true" or "yes".

  • How to invoke a custom adapter from a BPEL process

    Hi guys,
    I've implemented a custom outbound adapter and deployed successfully on Weblogic V.10.3.4.
    My current installation also consists of Oracle SOA Suite 11g / JDeveloper 11g (11.1.1.4.0)
    In the Weblogic administrator's console,
    *1.* I navigated to:
    Summary of Deployments -> AdapterName -> Configuration -> Outbound Connection Pools
    *2.* Selected: javax.resource.cci.ConnectionFactory and added new JNDI name for Outbound Connection Instance: "*eis/HelloWorld*"
    My task is to invoke the custom adapter from a BPEL process.
    I altered the customAdapter-config.xml so as to be able to use custom adapter wizard from JDeveloper's "Service Adapters" palette,
    and fullfilled the custom adapter wizard's fields accordingly. The 3rd step of the wizard requires Connection Information.
    I added: "*eis/HelloWorld*" in the "*Connection Factory Location*" field.
    Deployed BPEL process successfully, but testing failed due to binding.jca-12510 error:
    "The JCA Binding Component was unable to establish an outbound JCA CCI connection due to the following issue: BINDING.JCA-12510 JCA Resource Adapter location error. Unable to locate the JCA Resource Adapter via .jca binding file element <connection-factory/> The JCA Binding Component is unable to startup the Resource Adapter specified in the <connection-factory/> element: location='eis/HelloWorld'. The reason for this is most likely that either 1) the Resource Adapters RAR file has not been deployed successfully to the WebLogic Application server or 2) the '<jndi-name>' element in weblogic-ra.xml has not been set to eis/HelloWorld. In the last case you will have to add a new WebLogic JCA connection factory (deploy a RAR). Please correct this and then restart the Application Server "I tried to apply (just for testing) "eis/FileAdapter" in the "Connection Factory Location" field of the custom adapter wizard,
    and BPEL successfully invoked the adapter.
    Any ideas ?
    Thanks,
    George

    George, What deployment do you have this associated with?

  • How can one invoke a WebLogic EJB from a BPEL Server hosted on OC4J?

    How can one invoke a WebLogic EJB from a BPEL Server hosted on OC4J?
    Reason I ask is I keep getting this error:
    javax.naming.NoInitialContextException: Cannot instantiate cla
    ss: weblogic.jndi.WLInitialContextFactory [Root exception is java.lang.ClassNotF
    oundException: weblogic.jndi.WLInitialContextFactory]
    Note: I am using <bpelx:exec> as a way to execute some java program.
    Essentially my java client (essentially an EJB client hosted on Oc4J) needs access to wlclient.jar since it needs access to weblogic.jndi.WLInitialContextFactory. I have a EJB client running on BPEL server hosted on Oc4J that needs to access some EJBs hosted on weblogic.
    Where do I place this wlclient.jar so that BPEL PM can start peacefully and at runtime discover the InitialContextFactory classes?
    Placing it in the j2ee/home/applib doesn't solve the problem. The server fails to start up if I do this
    I tried placing it in BPEL-INF\lib directory ...
    I still get the same exception...see below for exception dump
    I verified the BPEL suitcase, and it in fact does contain the jar file wlclient.jar
    integration\orabpel\domains\default\deploy contains the bpel_BPELProcess2_1.0.jar file and snapshot of that is as follows:
    <PRE>
    &#9474; bpel.xml

    </PRE>
    I tried using the BPEL-INF\jar directory...Is this something the obant automatically detects? or do I have to modify the build.xml? I created this directory and let Jdev deploy to local BPEL server->default domain handle it
    #####################3
    I even tried copying the wlclient.jar to
    integration\orabpel\system\classes but this doesn't help since the BPEL PM fails to start if I explode this jar into this directory.
    In short,where do I place the wlclient.jar so that this exception can be contained.
    I edited the build.xml to point to the jar, that too didn't work, unless I made some mistake in the file
    <bpelc classpath="${basedir}/BPEL-INF/classes;${home}/system/classes;${home}/lib/j2ee_1.3.01.jar;${basedir}/BPEL-INF/jar/wlclient.jar" input="${basedir}/bpel.xml" rev="${rev}" deploy="${deploy}" />

    I did exactly as you suggested. I edited the application.xml and added this
    <library path="C:\ArcGIS\test\bea\wlclient.jar"/>
    I didn't add weblogic because the needed classes were all in wlclient.jar
    I also edited the BASE_OB_CLASSPATH to include this jar.
    Here is the result when I just start BPEL PM Server. Somehow BPEL PM doesn't like to have wlclient.jar in its classpath during startup.

  • Invoking an async  process from an async process

    I want to invoke an asynchronous process from an asynchronous process. My caller process has has a initiator task, a   message throw and catch event while called process has a start catch message  event and throw message as end event . If any one of you can provide a  sample or reference, it will be of great help.  I am have problem in configuring  end throw message  event .

    Where exactly do you have problems. When you use the async template you do not really have to configure anything - just define your input / putput data. This blogpost here describes how you can call an async BPEL from an async BPMN process: Oracle-FMW: Calling Async BPEL process from BPM.

  • Problem invoking a web service from soa11g BPEL.

    Hi ,
    I am trying to invoke a web service from soa bpel 11g composite.
    We have the wsdl, wsdl URL of the web service along with the user name , password credentials.
    Initially w/o any WS policy attached and testing the composite, it fails with the below message
    *<fault>*
    *<bpelFault>*
    *<faultType>0</faultType>*
    *<remoteFault>*
    *<part name="summary">*
    *<summary>An Authentication object was not found in the SecurityContext</summary>*
    *</part>*
    *<part name="detail">*
    *<detail>javax.xml.ws.soap.SOAPFaultException: An Authentication object was not found in the SecurityContext</detail>*
    *</part>*
    *<part name="code">*
    *<code>soap:Server</code>*
    *</part>*
    *</remoteFault>*
    *</bpelFault>*
    *</fault>*
    *<faultType>*
    *<message>0</message>*
    *</faultType>*
    *</messages>*
    So I have gone back to the composite and added the WS policy (oracle/wss_username_token_client_policy) by Right clicking on web service -> Configure WS Policy -> Security -> oracle/wss_username_token_client_policy -> OK.
    After this I have added the following binding properties 'oracle.webservices.auth.username' , 'oracle.webservices.auth.password' with the respective values and deployed it again.
    Even then I face the same issue. I have looked into the EM console and found the HTTP username and password properties were blank for this Web service even though the WS policy was attached.
    Later I have tried editing the username pwd from the EM console, only to find out that the composite was now failing in the previous step (an ordinary db adapter with a select statement) even before it reaches the web service invocation.
    If I redeploy the composite, the http username and pwd properties in the EM console are erased and when i test it, it errors out at the web service invocation with the same issue again.
    Any pointers on how to solve this issue ??
    How can I figure out what is the security policy the web service is using ??
    Regards,
    Shiva Kiran

    Hi,
    Can anyone help me with this ??
    I guess I am not able to send the authorization credentials via the request to the web service invocation.
    Plz help ! This is a bit urgent..

  • How to invoke an other BPM asynchronous process from the BPM process

    Do anyone know how to invoke other asynchronous process from the BPM process without using the Web Service URL?

    Try using a Service task implemented as a Process Call. Then you select the process you want to call, set the associations or transformation and deploy it to test.
    I hope it works for you.

  • Calling BPM Sub Process from another BPM Process - Stuck at Sub Process

    Hi
    JDeveloper 11.1.1.6, BPM 11.1.1.6, WLS 10.3.6
    I am trying to Call a BPM Process from another BPM Process. Both the processes are defined in the same BPM Project.
    Both the Processes have 'None' Start and End activities.
    The 'Parent Process' has a 'Call Activity' which calls the 'Sub Process'.
    The Sub process takes a parameter of payload object as input and returns output (also same payload object)
    I have passed the payload object from parent to sub process in the 'Data Associations'.
    The Start and End activities in the sub process also have the data associations set where I am passing the payload object from parent process to child process.
    When I run the process and see the Enterprise Manager console - Audit Trail / Flow tabs,
    Flow Tab - The progress of the process is showing only till the Calling of the sub process in the Parent Process. It does not show the Sub Process.
    Audit Trail Tab - Shows that the Sub Process is called but has not reached to the End of the Sub process.
    The audit trail does not have links to the sub process activities.
    I cannot see any exceptions as well in the audit trail.
    How can I find out why the process is stuck? Or what is going on in the process?
    Please let me know if my explanation is not clear?
    Thanks for any help
    Regards
    Sameer

    Thanks for replying.
    I have another Sub Process with Start and End events as Message Events and used Send Task and Receive Task (Implementation : Process Call) in the Main process to invoke the sub process asynchronously.
    Then, the Sub Process is shown in the 'Flow Trace' as child of the main process.
    In this particular one, I used 'Call Activity' to call the sub process.
    So the Audit trail is showing the sub process as a child.
    But what I was trying to say is that the audit trail did not have links to the entries in the 'Event' column (in Enterprice manager - instance window). (like Instance entered activity, Instance left activity etc).
    I was intending to use these links to see the payload information and try to debug if there is any problem with the code.
    The actual problem I was trying to say in the post is that, even after the user responds to the activity (User Task - Approval) in the Sub process,
    the audit trail is not proceeding further.
    In the Sub process definition, after the user task, there is End with none implementation.
    Hope it is clear now.
    Thanks and Regards

  • How to invoke an OSB service from a BPEL process

    I need help, to figure out how to invoke an OSB proxy service from a BPEL process.
    I found a blog which exactly does that; but I am unable to get it to work. I get the following error on my BPEL console. We are on OSB10gR3 and SOA 10134.
    "com.bea.wli.sb.transports.TransportException: Unknown error while processing message for service ProxyService DWIntegrations/ProxyService/PeopleServiceBus"
    Any help will be greatly appreciated.
    Regards,
    BP

    It really comes down to the proxy service on the OSB. Is it invoked by a WSDL? If so you should be able to take the endpoint defined in the proxy service messaging configuration and use that URL. You also need to use the sb transport type.
    Can you also post the blog you used, then we can put it into context.
    also have a look at this link.

  • Start a new process from a running process BPM 10.3 STUDIO!

    Is it possible to create a process in BPM Studio 10.3 from a running process.
    The scenario is that we have a process running listening to a jms queue an when a message
    arrives it's starts the process that was requested in the in message.
    /Getr

    if you have a Global Automatic activity listening to a JMS queue, here's how you can create a new work item instance in a process using logic in the Global Automatic activity's method. This uses the "Fuego.Lib.ProcessInstance.create()" method shown below:
    // "args" is an associative string array (Any[String])
    argsIn as Any[String]
    // this assumes that the Begin activity has two argument variables
    //   named "nameArg" and "amountArg" and you're setting them
    //   to the variables "name" and "amount" respectively
    argsIn["someArgVarName"] = "Hello"
    argsIn["someBpmObject"] = myBpmObject
    // logic here to determine the name of the process to create an instance in
    idOfProcess as String
    idOfProcess = <hard coded string that has the id (not the name of the process to instantiate>
    ProcessInstance.create(processId : "/" + idOfProcess, arguments : argsIn, argumentsSetName : "BeginIn") ProcessInstance is in the Catalog inside Fuego.Lib.
    The processId parameter (the "idOfProcess" variable in the above logic) is the thing I most commonly screw up with this. It is the text you see when you right mouse click the process in the Project Navigator tab -> "Properties". Look at the value in the "Id" field and not the "Name" field here (the name without any space characters). Prefix it with a "/" as is shown here and if you've deployed this using an organization unit (OU) then prefix this to the string also.
    The third parameter is almost always "BeginIn". Begin activities in a process can have many incoming argument mappings, the default is "BeginIn". To see yours, double click the process's Begin activity and look at the mapping's name in the upper left corner of the dialog.
    "argsIn" is the set of incoming argument variables you want passed into the process. A common mistake is to type in the names of the incoming argument variables without the double quotes like this:
    // this will *NOT* work
    argsIn[someArgVarName] = "Hello"
    argsIn[someBpmObject] = myBpmObject
    . . .Here is the correct syntax:
    // this *WILL* work
    argsIn["someArgVarName"] = "Hello"
    argsIn["someBpmObject"] = myBpmObject
    . . .In this example, the process has two argument variables. It does not matter if the incoming argument variables are primitive type arguments (e.g. String, Integer, Decimal...) or BPM Objects, it is always done the same way. In this example, there is a String incoming argument called "someArgVarName" and a BPM Object incoming argument called "someBpmObject".

  • How to get status of a sub process from the parent process.

    Hi,
    I want to get the status of a subprocess from the parent process (i.e. success or failure).
    How can I get this.
    Thanks in advance.
    Bye

    have a look at the workflow built-in vars:
    WF_ACTION_ERROR and WF_ACTION_RESULT or WF_CASE_RESULT

  • Killing a Java process from another Java process

    Hi
    Is there a possible way of sending a SIGINT, SIGKILL, or any other signal from a Java process running in one JVM, to a java process running in a different JVM on the same machine.
    I've the signal handlers written in my process and they do respond to singals (e.g. on pressing Ctrl-C) on the console, but i want to write a separate program that sends this signal to the first process.
    Any ideas?
    Thanks in advance and regards
    Kashif

    The answer, as always, is that Java can't do operating-system-specific things like that, but you can use JNI to do it. However, if your code created the Java process you want to kill, via Process p = Runtime.getRuntime().exec(...), then you can use p.destroy() to kill it.
