Hi All,
I'm trying to realize a complex use case with Jbpm 4, and I'm lookin for some advises and answers.
My requisites are to implements some kind of "phases" inside a business process (which models an authorization issuing system
for a governative trade organization) that can be "modular" and pluggable to the basis of some normative & legal factors.
I've move to the use of sub-processes in order to implement this, using a dynamic el expression to decide in runtime what process definition of
instantiate as sub-process, via parameterizing the jpdl sub-process' key attribute.
So the structure is composed by a main process, that groups these phases, and many other subprocesses which can can be
authored by external system and business designers.
Another requisite is that in one phase (es: when an integration request is started) the main process is paused,
a timer is started (the pause cannot be longer than a business value, and users must be notified if the suspension is reaching it's limit),
and then resumed.
For authoring sub-process I don't find seamless to design for any subprocess some kind of a "suspension" state
(this would be always present, and redundant), so I'm thinking to enforce the suspension state at the level of the main process:

I cannot use the execution suspension of the main process, because of the timer's requisite (execution "*suspended*" state, also suspend timers and notifications),and I cannot +end+ the sub-process because formally, at the end of the "wait" period it must progress where the sub-process was left.
The problem is that when signaling the main execution to the "Suspend" state, there is a running sub-process instance that invalidate the operation:

I've tried to suspend the sub-process activity execution and resume the main-process activity that maps the sub-process execution (the one in "inactive-scope" state) but it have no effect:
... ExecutionImpl execution = (ExecutionImpl) executionService.findExecutionById(processId);logger.info( "MAIN-PROCESS STATE= " + processId + " " + execution.getState() );if(execution.getSubProcessInstance() != null){ logger.info( "SUB_PROCESS STATE= " + execution.getSubProcessInstance().getId() + " " + execution.getSubProcessInstance().getState() ); if(Execution.STATE_INACTIVE_SCOPE.equalsIgnoreCase(execution.getSubProcessInstance().getState())){ ExecutionImpl state = execution.getSubProcessInstance().findActiveExecutionIn(activeState); state.suspend(); execution.getSubProcessInstance().suspend(); logger.info( "SUB_PROCESS STATE= " + execution.getSubProcessInstance().getId() + " " + execution.getSubProcessInstance().getState() ); logger.info( "SUB_PROCESS ACTIVITY STATE " + state + " " + state.getState() ); execution.resume(); logger.info( "MAIN-PROCESS STATE " + execution + " " + execution.getState() ); }} executionService.signalExecutionById(processId, transitionName, variables);
this is the log:

So, I'm wondering if the behaviour of Jbpm is wrong or if it's supposed to work in this way (namely: "cannot signal parent execution id subprocess are suspended"), or BTW if there is a common way to implement this set of requisites.
thank you in advance for any help you can give me!

Authentication with credentials and without for the same URL
by Tim Terlegård
I would like JBoss AS to handle authentication, but I would like to
handle the authorization programmatically.
If a client passes username/password I would like JBoss to
authenticate this request and pass the principal+roles to the servlet.
If the client doesn't pass any credentials I would still like the
servlet to be invoked but without any principal or roles. How can one
do this?
If I don't have any <security-constraint> in web.xml it doesn't seem
like authentication is triggered. I don't get any principal in my
servlet. If I have a <security-constraint> I must supply a role and
that won't work for unauthenticated users. Is there a way to trigger
authentication without having a <security-constraint> in web.xml?
Thanks,
Tim

[JBoss Tools] - Seam Generate Entities : classe not found

Hello Seamians ! :)
I've encountered some difficulties to create a Seam Web Project for Tomcat 6 using JBoss Tools but I've finally succeded and could see the "Welcome to Seam" page. You can see the operations on my http://blog.developpez.com/cinephil/p9314/java/jboss-seam/creer-un-projet... blog (in French).
Next step, I've a simple test MySQL database with only one very simple table called users.
I've used the JBoss Tools command "Seam Generate Entities" and a Users.java class has been created in src/org.domain.projettest.entity.
There was an error signaled at the @Entity annotation in the class : "This mapped class is not specified in persistence unit “hibernate”" and I've found the solution on http://edemmorny.wordpress.com/2009/04/28/using-eclipse-dali-with-hiberna... Edem Morny's Tech Blog to resume the error.
But now my project is not accessible. I have these errors in the console :
GRAVE: Exception lors de l'envoi de l'évènement contexte initialisé (context initialized) à l'instance de classe d'écoute (listener) org.jboss.seam.servlet.SeamListener
org.jboss.seam.InstantiationException: Could not instantiate Seam component: entityManagerFactory
...
Caused by: javax.persistence.PersistenceException: [PersistenceUnit: projettest] class or package not found
at org.hibernate.ejb.Ejb3Configuration.addNamedAnnotatedClasses(Ejb3Configuration.java:1093)
...
Caused by: java.lang.ClassNotFoundException: org.domain.projettest.entity.Users
What's wrong ?

[JBoss Web Services] - Error: Unsupported Java encoding for writing wsdl file: 'ISO8859_15'.

Hello,
I'm having problems publishing a Web Service on JBoss AS 4.2.3 with *jbossws-native-3.1.1.GA*
This is the code:
@WebService
public interface ZDepTestWSInterface { @WebMethod Integer getZValue(@WebParam(name="value") Integer value);}
@Stateless@WebService(endpointInterface="hugo.deptest.a.api.ZDepTestWSInterface")public class ZDepWS implements ZDepTestInterfaceRemote, ZDepTestWSInterface { public Integer getZValue(Integer value) { return value + 2; } }
@WebService
public interface ZDepTestWSInterface {
@WebMethod
Integer getZValue(@WebParam(name="value") Integer value);
}
I'm deploying on a Linux machine.
If the locale is en_US.UTF-8 everything works ok.
But if the locale is pt_PT@euro, i get the following exception:
---
org.jboss.ws.WSException: Cannot publish wsdl to: /home/jboss/jboss-4.2.3.GA/server/all/data/wsdl/ZTest.ear/ZTest-EJB.jar/ZDepWSService2420312176256736548.wsdl

This only happens if i use the endpointInterface on the WebService annotation.
If i expose the getZValue as a WebMethod on the Staless bean class everything works ok.
I don't know what is wrong. Can you please help ?
Thank you
