--------------------------------------------------------------
Hi Everyone.
I am stuck with a concurrency problem using jBPM 5.3. The error I am facing is similar to this one:
http://drools.46999.n3.nabble.com/rules-users-Transaction-problems-in-high-concurrency-JBPM-Drools-Hibernate-instalation-td4020798.html http://drools.46999.n3.nabble.com/rules-users-Transaction-problems-in-high-concurrency-JBPM-Drools-Hibernate-instalation-td4020798.html
I have a Jbpm 5.3 + RestEasy deployed in Jboss AS 7.
When I try to make two complete task operations at the same time, the errors arises. This error is not always the same. Some of then are like this:

I have made a simple maven app where I can reproduce the issue.
To run this app, compile it using *mvn clean package*.
Inside *config* folder, there is an standalone.xml file which is the one I am using.
I deployed designer and drools-guvnor 5.4 and I have put a repository_export.xml file inside *config* folder.
Then put test.*war* file to the jboss AS 7.1.1 *standalone/deployments.*
*
*
There is a service to view the processes:
http://localhost:8080/test/services/process/processes/available http://localhost:8080/test/services/process/processes/available
Then, start two processes with this call:
http://localhost:8080/test/services/process/startprocess/data?userid=calcacuervo&processid=defaultPackage.test http://localhost:8080/test/services/process/startprocess/data?userid=calcacuervo&processid=defaultPackage.test
Then, for each one you can get the next task for each process instance:
http://localhost:8080/test/services/process/nextTask/data?userid=calcacuervo&processinstance= http://localhost:8080/test/services/process/nextTask/data?userid=calcacuervo&processinstance=*41*.
You will get the task id, and then, using this call you will be able to complete the task. After that you will be able to call the previous service call and a new call will arise:
http://localhost:8080/test/services/process/complete/data?userid=calcacuervo&taskid=55&answer=1 http://localhost:8080/test/services/process/complete/data?userid=calcacuervo&taskid=55&answer=1
I have put a breakpoint in com.test.ws.JBPMProcessServiceImpl.answer(String, String, String), and called this *complete* service call twice, and I can reproduce the reported errors.
Could you please give me some advice on what I am doing wrong to get these problems?
Thanks in advance,
Leo
(on behalf of calcacuervo)
