Seam Managed ActionHandler
Hello all,
I'm trying to create a seam managed Action Handler for a jbpm node ( not a task node ). I want to inject a variable into this action which is outjected in a another SLSB.
My process definition:
<?xml version="1.0"?>
<process-definition name="inkless">
<start-state name="start">
<transition name="" to="node1"></transition>
</start-state>
<end-state name="end1"></end-state>
<node name="node1">
<action name="action1" expression="#{bar.foo}"/>
<transition name="" to="end1"></transition>
</node>
</process-definition>
The code that creates the process and Outjects a Context variable:
@Stateless
@Name("inklessProcessManager")
@Interceptors(SeamInterceptor.class)
public class InklessProcessManagerImpl implements InklessProcessManager {
@Out(scope=ScopeType.BUSINESS_PROCESS, value="foo") Integer someThing;
@CreateProcess(definition="inkless")
public void startProcess() {
someThing=new Integer(5);
}
}
And now my actionhandler which is called in the process definition:
@Stateless
@Name("bar")
@Interceptors(SeamInterceptor.class)
public class BlahBlahActionHandler implements IActionHandler {
/* (non-Javadoc)
* @see com.melexis.inkless.IActionHandler#foo()
*/
@In(value="foo", scope=ScopeType.BUSINESS_PROCESS) Integer foe;
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public void foo(){
System.out.println("Foooooooooooooo");
System.out.println(foe);
}
}
And finally the exception i receive:
Caused by: javax.ejb.EJBException: org.jboss.seam.RequiredException: In attribute requires non-null value: bar.foo at org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:63) at org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:83) at org.jboss.aspects.tx.TxInterceptor$RequiresNew.invoke(TxInterceptor.java:253) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.tx.TxPropagationInterceptor.invoke(TxPropagationInterceptor.java:76) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessInstanceInterceptor.invoke(StatelessInstanceInterceptor.java:62) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.security.AuthenticationInterceptor.invoke(AuthenticationInterceptor.java:77) at org.jboss.ejb3.security.Ejb3AuthenticationInterceptor.invoke(Ejb3AuthenticationInterceptor.java:106) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.ENCPropagationInterceptor.invoke(ENCPropagationInterceptor.java:46) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.asynchronous.AsynchronousInterceptor.invoke(AsynchronousInterceptor.java:106) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessContainer.localInvoke(StatelessContainer.java:214) at org.jboss.ejb3.stateless.StatelessContainer.localInvoke(StatelessContainer.java:184) at org.jboss.ejb3.stateless.StatelessLocalProxy.invoke(StatelessLocalProxy.java:81) at $Proxy101.foo(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.seam.util.Reflections.invoke(Reflections.java:21) at org.jboss.seam.intercept.RootInvocationContext.proceed(RootInvocationContext.java:31) at org.jboss.seam.intercept.ClientSideInterceptor$1.proceed(ClientSideInterceptor.java:76) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:56) at org.jboss.seam.intercept.RootInterceptor.invoke(RootInterceptor.java:106) at org.jboss.seam.intercept.ClientSideInterceptor.invoke(ClientSideInterceptor.java:54) at org.javassist.tmp.java.lang.Object_$$_javassist_2.foo(Object_$$_javassist_2.java) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.el.util.ReflectionUtil.invokeMethod(ReflectionUtil.java:328) ... 170 more
I'm just starting out with jboss seam so it might be my own incompetence, but i think i understood the documentation correctly.
Can someone point out what i'm doing wrong? Thank you.
Best regards,
Jo
