Problem invoking BPEL process via SOAP

Hi,
I have a BPEL process which runs perfectly when invoked from the BPEL console. Now I try to invoke the BPEL process from another (Java) program and get some strange error message in the client. After enabling debug logging I can see a NullPointerException in the BPEL server log (it's Oracle BPEL server 2.1.2 build 1226).
Here the output from the console:
15:21:40,088 INFO [STDOUT] <2006-03-24 15:21:40,088> <DEBUG> <default.collaxa.cube.ws> <CXSOAPProvider::processBPELMessage> soapAction:

Thanks in advance...

This sounds very similar to how my BPEL process behaves. I'm unable to post XML input into the "XML Source" region of the initiate screen unless the input is properly wrapped in the respective message type element.
Make sure your invoking client code is wrapping the input properly with the message type XML elements.

Authorization Error While Invoking BPEL Process Via RMI

Hi All,
I have been trying to invoke BPEL Process via RMI client.
I use the following piece of code for BPEL Process Invocation...
public class RMIClient {
public RMIClient() {
public static void main(String[] args){
Hashtable jndi = new Hashtable ();
jndi.put (Context.PROVIDER_URL, "opmn:ormi://host:6010:oc4j_soa/orabpel");
jndi.put (Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
jndi.put (Context.SECURITY_PRINCIPAL,"oc4jadmin"); // username of Bpel Manager
jndi.put (Context.SECURITY_CREDENTIALS,"welcome1"); //password of BPEL Manager
Locator locator=null;
try {
locator = new Locator("default",jndi);
} catch (ServerException e) {
e.printStackTrace();
IDeliveryService deliveryService =
(IDeliveryService)locator.lookupService
(IDeliveryService.SERVICE_NAME );
// construct the normalized message and send to oracle bpel process
NormalizedMessage nm = new NormalizedMessage( );
String xml = "<ns1:MyFirstBPELProjectProcessRequest xmlns:ns1=\"http://xmlns.oracle.com/MyFirstBPELProject\">\n" +
" <ns1:input></ns1:input>\n" +
" </ns1:MyFirstBPELProjectProcessRequest>";
nm.addPart("payload", xml );
NormalizedMessage res=null;
try {
res = deliveryService.request("MyFirstBPELProject", "process", nm);
} catch (ServerException e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
Map payload = res.getPayload();
When I try to connect to my locally deployed BPEL process Manager and Invoke the same process (MyFirstBPELProjectProcess ) it works fine and creates an Instance on BPEL Process Manager Console.
When I tried Invoking the same BPEL process (MyFirstBPELProjectProcess ) deployed on a Remote machine ,it doesnt create an Instance.
I believe my connections settings are all correct ,since it doesnt give me an connection issue on my standalone client.
I tried looking at the following file default_group~oc4j_soa~default_group~1.log available opmn folder under SOA Suite OAS and there
are no errors.
Could some body point the log files that I need to look at.
I am sort of clueless...
Regards
Harish

CAn you post the error. HAve you made sure that the remote machine has connection on the port 6010. You can test this with the folloing command from the remote machine
telnet host 6010
obviously replace host with the fully qualified host name of the SOA machine.

How to invoke BPEL process via HTTP POST (or GET)

Hi,
I'd like to know how to invoke BPEL process via HTTP POST (or GET), is there anyway simple to do it?
Thank you

Look at my blog http://orasoa.blogspot.com search for plsql
or use SoapUI.org
or look in the Examples directory in the BPEL directory of the installation

Invoke Bpel Processes via API or Web Service Proxy Clients

Hi all,
I was wondering if any of the felow community members have found information regarding best practices in invoking bpel processes from a user interface other than ADF Faces?
Currently I'm using Web Service Proxy Clients to invoke my bpel processes, but I was wondering if it would be better to use the BPEL API?
Considerations I have regarding these 2 different approaches are mostly tight integration when using the BPEL API, because this means I have to port the BPEL (Oracle Code) inside my UI-application which isn't the case when using Web Service Proxy Clients.
What is the best way to instantiate bpel processes from a user interface, is that by using web service proxy clients or by using the bpel i
nvocation API?
Kind regards,
Nathalie

Hi Marc,
These were my considerations as well, but I was looking for some kind of benchmarking regarding these 2 approaches. What's best practices when hooking up bpel inside UI Applications regarding performance, future-proofness (SOA Grid, SOA Composites, ...) etc.
I think I need to discuss this with the product team to make sure I'm taking the wright decisions.
Kind regards,
Nathalie

Invoking BPEL WS via SOAP

Accessing BPEL processes via a proxy web service performance issues

Hello,
I have more BPEL processes implemented, each such a process implementing business functionality in a certain domain (generally, a domain has more business processes).
The request was to provide a single web service for each domain. It means that all the business methods (processes) in the same domain should be accessed through the same web service. This request doesn't make possible to expose the BPEL processes themselves as web services that could be directly consumed by different clients of the application.
The alternative will be to implement the "domain" web services through a Java class, for instance. With this approach, the Java based domain web services will expose the needed business methods to the clients. And the Java class will get the request input parameters and will call the corresponding BPEL process via SOAP. This scenario would be fine, but... this approach would imply a supplementary marshalling/unmarshalling process at the domain web service level. The data returned by the BPEL processes could be very large and in such a situation the Java based domain web service will introduce an important performance drawback.
Is there any other solution to this case that will allow the using of a "proxy" domain web services that will not introduce any important drawback via marshalling/unmarshalling?
Many thanks in advance!

Hello,
First, thank you Sandor for your answer.
I understand that it is possible to create a BPEL process that exposes multiple operations/messages. This would be exactly what I need: a single process (web service) that will expose many operations. Could anyone, please, point me to such an example?
So far I thought that there is possible to have only one operation exposed with a BPEL process, what is delimited between the receive/reply blocks (in the synchronous case).

Invoking a BPEL Process via Java Remote Client

Hi everyone!
I want to invoke a BPEL process from my Java Application which is not running on the same Application-Server (not the same Java RE) as the BPEL processmanager does.
For Applications running on the same AS there is the IDeliveryService class to which you can send a XML-request in order to invoke a BPEL process.
Is the only way to invoke a BPEL Process from an external application to use a webservice client or is there a similar class for java remote clients?
For access to the users worklist I use
IWorkflowServiceClient wfClient = WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory.REMOTE_CLIENT);
it works fine an I thought there might be a similar way to invoke a bpel process via remote too.
If anyone knows if it's possible or not please tell me ;)
Thanks in advance
Markus

Hello,
Here is the code I use:
Properties props = new Properties();
Locator locator = null;
props.put("orabpel.platform", "ias_10g" );
props.put("java.naming.factory.initial","com.evermind.server.rmi.RMIInitialContextFactory" );
props.put("java.naming.provider.url","opmn:ormi://host:port/orabpel" );
props.put("java.naming.security.principal", "adminuser" );
props.put("java.naming.security.credentials", "mdp" );
String securityCredentials = "adminuser";
String selectedDomain = "default";
locator = new Locator(selectedDomain,securityCredentials,props);
IBPELProcessHandle procs[] = locator.listProcesses();
The error is:
Exception in thread "main" java.rmi.UnmarshalException: Error deserializing return-value: java.io.InvalidClassException: com.oracle.bpel.client.BPELProcessHandle; local class incompatible: stream classdesc serialVersionUID = 5429682712928177644, local class serialVersionUID = 8176841433835717563

Thanks for help.

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.

Initiate process via SOAP

Hi all.
I initiate an instance of process via SOAP (Axis2) the first one works fine
but the rest throws exception.
When I restart the server(in JDev) the same scenario occurs
08/02/02 16:52:51 org.apache.axis2.AxisFault: java.lang.NullPointerException
08/02/02 16:52:51      at org.apache.axis2.util.Utils.getInboundFaultFromMessageContext(Utils.java:486)

08/02/02 16:52:51      at org.apache.axis2.client.OperationClient.execute(OperationClient.java:163)

This sounds very similar to how my BPEL process behaves. I'm unable to post XML input into the "XML Source" region of the initiate screen unless the input is properly wrapped in the respective message type element.
Make sure your invoking client code is wrapping the input properly with the message type XML elements.

Invoke BPEL process with the webservice interface

I'm using Oracle BPEL PM 10.1.2.x.
Follow the example comes with the BPEL PM, i can invoke the BPEL process in a J2EE project (with the webservice interface). The example named "UseStockReviewSheet".
Then i tried to invoke the BPEL process i designed with Eclipse BPEL Designer. The version of BPEL designer for Eclipse is 0.9.13.
I failed and got following errors:

I can invoke my BPEL process in BPEL console, not in J2EE project. bpws:getVariableData('input','payload','/tns:CreditFlowRequest/tns:input')" is null.
The error message contains some Chineses word. I'm new to BPEL, hope someone can give me a hint on how to solve this problem.
Thanks a billion!

Null Pointer exception while invoking BPEL process

Hi all,
I am getting following exception when I am invoking a BPEL process1 (deployed in 10.1.3.1) from another BPEL Process 2 (deployed in 10.1.3.3)
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">

</env:Body>
</env:Envelope>
BPEL Process 1 is working fine when given manual input (testing through console). But when invoked using BPEL Process 2, it gives the above error. I also tried invoking BPEL Process 1 (and many other webservices deployed in 10.1.3.1) using TCPMON tool and got the same error.
Am I missing something here in configuration of 10.1.3.1 or any other issue? Please help as it is really urgent.

Hi,
Switching on or off a bpel is an admin job.
u can stop an application but not one bpel.
I doubt if there is any way to do it programatically.
Let us get other opinons
