Hi all.
I'm trying to invoke a web service from my jBoss/jBPM process.
As Ronald suggests in this post:
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=70723
I write an actionhandler which invokes the webservice and then I associate it
on a node-enter event of a node.
But when I run the process from jBoss-jBpm console I get an exception
description The server encountered an internal error () that prevented it from
fulfilling this request.

|

{
| // Make the call
| String method = new String("Get_CodFisFromLocalita");
| String endpoint = "http://www.nexusonline.it:8088/4DWSDL";;
| String city = (String) ("Milano");
|
| Service service = new Service();
| Call call = (Call) service.createCall();
|
| call.setTargetEndpointAddress(new java.net.URL(endpoint));
| call.setOperationName( method );
| call.addParameter(city, XMLType.XSD_STRING, ParameterMode.IN);
| call.setReturnType(XMLType.XSD_STRING);
|
| String ret = (String) call.invoke( new Object[] { city } );
|
| executionContext.getContextInstance().createVariable("sigla",
ret);
|
| System.out.println("Result: " + ret);
| }
|
| }
|
Note:
I deploy the process by mean jBPD Eclipse plugin.
Any help will be appreciated.
Thank you!
