Hi all,
it is very important for me to get your assistance.
I want to know if it's possible to assign two or more users to a task ?
for example : titi or toto approval task2
If it's possible , how to do this ?
I want a complete example because I have reading lot of topic and they are never full
in processDefinition , in java part , in DB part , in jsp part.
for me only this work fine :
<task-node name="step2">
<task name="step2">
<assignment actor-id="toto" />
</task>
<transition name="toStep3" to="step3" />
<transition name="cancel" to="error" />
</task-node>
or
<task-node name="step2">
<task name="step2">
<assignment class="com.test.CRWAssignmentHandler" />
</task>
<transition name="toStep3" to="step3" />
<transition name="cancel" to="error" />
</task-node>
with CRWAssignmentHandler :
public class CrwAssignmentHandler implements AssignmentHandler{
private static final long serialVersionUID = -1101067351863423573L;
public void assign(Assignable assignable, ExecutionContext executionContext) throws Exception {
assignable.setActorId("toto");
}
}
I tryed to use swimlane , assignment pooledActors , etc ... none works correctly.
Please help me , is for my job !
Thanks in advance for your replies and sorry for my bad english :p
regards,
Leod

Hi Brian,
We are working on documentation and more sources of information like a jBPM5 book, but it's all work in progress.. I would like to help you to understand how components interacts in the mean time.
If you take a look at the MinaTaskServer, I think that will be easier for you to understand because it's a plain socket communication based on messages.
The HornetQTaskServer works in the same way but adding all the advantages of using a JMS client/server. You will get message retrying, message reliability and Queues clustering for free. Depending on your requirements you can choose the Mina Server or the HornetQServer, or you can implement your own transport to fulfill your requirements.
I will be glad to help you and I'm also will start writing some post about those topics with examples. Thanks for the feedback and if you have doubts or if you find issues let us know!
Greetings!

[jBPM] - HornetQTaskServer

I'm looking at integration of jBPM5 (using the CR1 release with the 5.2.0-alpha version of drools) with our web application and am trying to learn how the human task interface works to see how I might use it to interact with our web interface. We need to have a list of tasks inside one of our pages and interact with it in various ways.
I came across the HornetQTaskServer and am curious about how this is used. I cannot find any documentation or examples for this. Anyone familiar with this and have some idea how and when it should be used?
I have to say that I am struggling to get my mind around how jBPM is integrated into our environment, there doesn't seem to be a lot of documentation available and the lack of much in the way of javadoc comments in the classes makes it hard work understanding how it all works. Class comments giving a brief explanation of a class's purpose would be great.

[JBoss Web Services] - Custom exception not thrown

"Custom exception not thrown"

--------------------------------------------------------------
Hello,
i have a problem throwing a custom exception in a web method - the stacktrace lead me to a NPE in
I use JBoss 4.2.2 GA and JBossWS 3.0.5 native.
In the web service class i defined 2 methods, which are just throwing a custom exception -
one method without parameters and one with 1 input parameter:
{code}
@Stateless
@WebService
@WebContext(contextRoot = ConfigConstants.CONTEXT_ROOT,
authMethod = ConfigConstants.AUTH_METHOD,
transportGuarantee = ConfigConstants.TRANSPORT_GUARANTEE,
secureWSDLAccess = ConfigConstants.SECURE_WSDL_ACCESS)
@SOAPBinding(style= SOAPBinding.Style.RPC)
@RolesAllowed({ConfigConstants.ROLE_USI_USER})
@SecurityDomain(ConfigConstants.SECURITY_DOMAIN)
public class TestServer
{
@WebMethod
@WebResult(name = "companyList")
public CompanyList getAvailabeCompanyList() throws SystemException
{
if(true) throw new SystemException("getAvailabeCompanyList ");
return null;
}
@WebMethod
@WebResult(name = "companyList2")
public CompanyList getAvailabeCompanyList2(
@WebParam(name = "str") String str
) throws SystemException
{
if(true) throw new SystemException("getAvailabeCompanyList2 " + str);
return null;
}
}
{code}
When i call the methods, the one with an input parameter (getAvailabeCompanyList2) correctly throws the exception,
but the method without input parameter fails with the following stacktrace:
{noformat}

instead of the custom exception.
For the other method, its the supposed one:

So here the questions:
- Do i have an error in the code ?
- Is this a bug ?
- If yes, is it known or even fixed ?
Any hint or solution is welcome.
Best regards,
Timo

[Javassist] - Problem with equals/hashCode?
by James Garrison
James Garrison [http://community.jboss.org/people/jgarrison] created the discussion
"Problem with equals/hashCode?"
To view the discussion, visit: http://community.jboss.org/message/582176#582176
--------------------------------------------------------------
When MethodHandler.invoke() is called by Javassist for invocations of equals() and hashCode(), the "proceed" method object is not named "equals" or "hashCode", but is instead something like _d2hashCode. This is different from normal method invocation where the proceed method is the superclass implementation. Why does the generated proxy provide an implementation of these two methods?
We're trying to implement a proxy wrapper for an object that implements its own hashCode and equals, and would like to detect this situation so as to delegate to the wrapped object's equals() and hashCode(). Since the method name is mangled, what can we rely on to detect this situation unequivocally? What I've come up with is the following, to determine the actual implementation class for equals() and hashCode().
private Class<?> getRealDeclaringClass(Method m) throws NoSuchMethodException
{
Class<?> dcl = m.getDeclaringClass();
String name = m.getName().contains("equals") ? "equals" : m.getName().contains("hashCode") ? "hashCode" : null;
if (name != null)
{
Method impl = m.getDeclaringClass().getSuperclass().getMethod(name,m.getParameterTypes());
dcl = impl.getDeclaringClass();
}
return dcl;
}
Is this correct?

Please help!
