Hi, I'm a new user en jbpm and I have one problem executing an Action.
Here is the error

and this is the code of the handler:
|
|
|
| public class SpringInvocationHandler implements ActionHandler
| {
|
| private String oResultVariable;
|
| private String sWSServiceUrl;
|
| private String sBeanName;
|
| private String sExtraParam;
|
| /**
| * @see
org.jbpm.graph.def.ActionHandler#execute(org.jbpm.graph.exe.ExecutionContext)
| */
| public void execute( final ExecutionContext executionContext )
| {
| try
| {
| final Map<Object, Object> oProcessParams =
| (Map)
executionContext.getProcessInstance().getContextInstance().getVariables();
|
| if (sExtraParam != null)
| {
| String[] aMapContent = sExtraParam.split( "=" );
| if (aMapContent != null && aMapContent.length == 2)
| {
| oProcessParams.put( aMapContent[0], aMapContent[1] );
| }
| }
|
| final String sInstanceId =
| String.valueOf( executionContext.getToken().getId() );
| final String sProcessName =
| executionContext.getToken().getNode().getName();
| final Service serviceModel =
| new ObjectServiceFactory().create( IWSFrontController.class );
| final XFire xfire = XFireFactory.newInstance().getXFire();
| final XFireProxyFactory factory = new XFireProxyFactory( xfire );
|
| try
| {
| final IWSFrontController oSpringClient =
| (IWSFrontController) factory.create( serviceModel, sWSServiceUrl
);
| final Object oResult =
| oSpringClient.execute( sBeanName, sInstanceId, sProcessName,
oProcessParams );
| executionContext.setVariable( oResultVariable, oResult );
| } catch (Exception e)
| {
| e.printStackTrace();
| }
| } catch (Exception e)
| {
| e.printStackTrace();
| }
| }
| ...
|
| (plus the getter and setter of the fields).
|
I try the config-type field and bean whith the same result.
If I see the source code of Action (line 151) the error belong a manual cast and later
execution of the handler. But if I try this:
| String sConf =
| "<oResultVariable
xmlns=\"urn:jbpm.org:jpdl-3.2\">result</oResultVariable><sBeanName
xmlns=\"urn:jbpm.org:jpdl-3.2\">remaingTimesvc</sBeanName><sWSServiceUrl
xmlns=\"urn:jbpm.org:jpdl-3.2\">http://10.0.0.126:8080/services/WSFrontController</sWSServiceUrl>";
| Object o =
| new FieldInstantiator().instantiate( jbpm.SpringInvocationHandler.class,
sConf );
| ActionHandler o1 = (ActionHandler) o;
|
works fine.
The jbpm version is 3.2.1.
Any idea?
Thanks in advice.
