Hello,
I'm trying to run JBPM 5.4 inside an OSGi container. I've encountered a problem when using JPAKnowledgeService.newStatefulKnowledgeSession.
I get following error:
java.lang.RuntimeException: Provider org.drools.persistence.jpa.KnowledgeStoreServiceImpl could not be set.
at org.drools.persistence.jpa.JPAKnowledgeService.loadProvider(JPAKnowledgeService.java:155)
at org.drools.persistence.jpa.JPAKnowledgeService.getJPAKnowledgeServiceProvider(JPAKnowledgeService.java:143)
at org.drools.persistence.jpa.JPAKnowledgeService.newStatefulKnowledgeSession(JPAKnowledgeService.java:122)
....
Caused by: java.lang.ClassNotFoundException: org.drools.persistence.jpa.KnowledgeStoreServiceImpl
I found out that JPAKnowledgeService uses reflection to instantiate KnowledgeStoreServiceImpl class. Both classes are in org.drools.persistence.jpa package, but one is knowledge-api-5.5.0.Final.jar and second is in drools-persistence-jpa-5.5.0.Final.jar.
I'm not an OSGi expert, but I think that both classes should be in one .jar file (currently it's "split packages" problem).
Currently I have a workaround to use KnowledgetStoreServiceImpl directly and not use JPAKnowledgeService.
Or is there another workaround?

[jBPM] - Human task escalation understanding

Hi community,
I have some questions about Human Task node in jbpm v5.4. Actually I am designing a sample process that contains two human tasks ,in the second one I had defined Escalation mechanism ( when task is not-started , set expires at to 60s and set user Id).
When process reaches the second node of my process I see that after 60s , that Task status ( in jbpm database table Task) changed from "Reserved" to "Ready", but no user is assigned on that task (actualOwner_id had been changed to NULL) . I was wondering what could be the cause of that ?
I tried to see the java API but I did not find how I can catch the escalation event for Human Task , May I have any idea or help about how I can do that ? because actually what I am trying to do is when "Human Task" had been reassigned to another user , I should call a Java method to update some data on my application.
Regards

[jBPM] - Problem with designer

Hi!
I have one problem in designer.
I create a new simple process, with an start and end node, in the designer inside guvnor 5.4. I save it.
Then, I update the process using Guvnor Rest API. I make a PUT to http://localhost:8080/drools-guvnor/rest/packages/TestNewPathways/assets/... http://localhost:8080/drools-guvnor/rest/packages/TestNewPathways/assets/..., with content type application-octet stream, passing the string.getBytes of the modified bpmn.
Then, I go to the designer, and I can see the changes into the process. But then, I try just to save the process there and I get an error into the screen, and an exception in logs that I will paste below. Any ideas of what could it cause it?
Thanks!
Demian

[JBoss Web Services] - Migrating secured WS from JBoss 5.1 to 7.1.1

Hi,
I've been migrating one of our projects from JBoss 5.1 to 7.1.1, all was done without too much problems but I'm stuck on the security configuration for a Web Service (which does not have WS-Security Policy):
In JBoss 5.1, configuring WS-Security was done within the file "META-INF/jboss-wsse-server.xml"
<jboss-ws-security>
<key-store-file>${wsse.keystore}</key-store-file>
<key-store-type>jks</key-store-type>
<key-store-password>${wsse.keystore.password}</key-store-password>
<trust-store-file>${wsse.truststore}</trust-store-file>
<trust-store-type>jks</trust-store-type>
<trust-store-password>${wsse.truststore.password}</trust-store-password>
<config>
<timestamp ttl="3000" />
<sign type="x509v3" alias="${wsse.keystore.alias}" />
<requires>
<timestamp maxAge="3000" />
<signature />
</requires>
</config>
</jboss-ws-security>
So, I just need requests and responses to be signed and timestamped but I have a hard time understanding how to achieve this in AS7.1.1.
I've read the page https://docs.jboss.org/author/display/JBWS/WS-Security https://docs.jboss.org/author/display/JBWS/WS-Security, but it didn't help.
Do I need to configure this via jbossws-cxf.xml? (tried this but seems to be ignored)
Is it available out-of-the-box in JBoss AS7.1.1? (I see spring is being used but there are no spring jars in the distribution)
I must be missing something...
Thanks,
Xavier
