I'm using
jbpm-5.2.0.Final
jbpm-5.2.0.Final-gwt-console
guvnor-distribution-wars-5.3.1.Final
on
jboss-as-7.0.1
I could create process definitions in Eclipse, add them to Guvnor, build the package, create snapshots, etc. But when trying to see process definitions in jbpm-console, I just see nothing.
If I try using the rest api ( http://127.0.0.1:8080/gwt-console-server/rs/process/definitions http://127.0.0.1:8080/gwt-console-server/rs/process/definitions), I get:
{"definitions":[]}
(and JBoss logs says that parsed 0 process definitions).
I've made several packages in Guvnor, and jbpm-console seems to be trying to parse processes from all of them, but keeps saying he got 0 processes to parse.
Here I upload a list of assets obtained from the Guvnor's rest api ( http://127.0.0.1:8080/drools-guvnor/rest/packages/defaultPackage/assets http://127.0.0.1:8080/drools-guvnor/rest/packages/defaultPackage/assets).
Should jbpm-console see any process? What does a process definition look like in the rest API when it is parseable by jbpm-console?
Thanks a lot,
Roger

[jBPM] - jbpm5 scale out reference architecture..

After scavenging the forums and docs for jbpm 5 over the last week, I have drafted up the attached 'reference architecture' for a scalable jBPM 5 deployment. Would love to get feedback (aka ripped apart :) ).
Here are the key pieces:
1. A shared KnowlegeBase which acts as a repository of processes across the whole deployment (master-slave replicated with writes-to-master and reads-from-slaves etc etc)
2. There are a fixed number of KnowledgeSessions spread across DBs in a DB farm (DB1, DB2)
3. A table contains the mapping between these sessions, the database that they are stored in and the node that is assigned to these sessions. Management of the data in this table is an admin config operation (either automatic or manual).
4. A number of worker nodes which load the KnowledgeSessions that belong to them (as per the table above)
5. Another table that has mapping of processes-to-sessions. This table is updated by the worker nodes when a new process is created.
6. A router or client proxy that routes process instance managment requests as per the following rules:
- For process instance creation requests, round robin to any node
- For requests pertaining to a specific process instance, consult the table in (5) & (6) and route to appropriate node
Now how to scale out:
- If the bottleneck is the CPU/memory of the worker nodes then add more nodes and rebalance the session distribution in table (3)
- If the bottleneck is the DB capacity or disk then add a database, migrate processes/session data to the new database and update table (3)
Of course the resharding above is crude and manual and can probably be more sophisticated but would love to hear thoughts/comments on the basic idea.
Also practically speaking, I hope it is possible to migrate a session and processes to a different DB at all?
Thanks

Dear all:
I created a jbpm project only include .bpmn file and .ftl file, I start and execute process by jbpm console. At first, a user task node 's +ActorId+ I fill in "john",
and I can use john login console and see personal task. But when I fill in the user task node 's +ActorId as "jimmy" or other name which I set in+
+/jbpm-installer/jboss-5.1.0.GA/server/default/conf/users.properties, I only can login the console ,and start a process,but can't be assigned a personal task.+
+My question is : why only set+ user task node 's +ActorId as "krisv","john",or "mary" can be assigned task, if set+ user task node 's +ActorId as other names in "users.properties",+
+only can login console,but can't assign personal task?+
the content of file users.properties:
admin=admin
krisv=krisv
john=john
mary=mary
jimmy=jimmy
hawis=hawis
marvin=marvin
william=william
daniel=daniel
kim=kim
jason=jason
yuri=yuri

Hi all!
I'm seeing this error also, and don't know how to get over it. I am using JBoss AS 5.1.0.GA with jboss-remoting 2.5.1, and also checked with jboss-remoting.jar 2.5.4.SP3 in client and common/lib folders (not sure if I should replace more JARs)
These are the tests that I have done so far:

Don't know if this was solved by the original poster somehow, but if someone has a clue where to keep looking, I'd be much obliged!

[jBPM] - jBpm 5.2 persistence problem - Oracle - Unknown entity: org.drools.persistence.info.SessionInfo

--------------------------------------------------------------
Hi , I am setting up jBpm 5.2 with persistence for the first time and facing a LoT of issues. I am using jpm 5.2 with Spring 3.0 and Hibernate 3.5.6 on jBoss AS 7 server.
We all know that jBoss AS 7 comes with Hibernate 4 as the default hibernate , but I need to use the Hibernate 3 in my project so I installed hibernate 3 as a module in as7 and that is working as expected . I excluded Hibernate 4 with jboss-deployment-structure.xml and added org.jboss.as.jpa.hibernate:3 as a dependency in manifest.mf [refer http://badr-elhouari.blogspot.in/2011/10/how-to-use-hibernate-3-as-jpa-pr... here how I added hibernate:3 as a module in AS7]
That said , I have configured the entire knowledge base and knowledge session in spring so that I dont have to write code for that - Taking tips from drools - integration module and by using drools-grid-impl jar and drools-spring jar.
Drools-grid jar contains a persistence.xml which used in memory DB [h2] so I modified the xml to use oracle and hibernate 3 instead.
Here is my *application context*:
