结合使用jBPM 5.4和简单的Java EE应用程序

Question

i'm currently working in jBPM 5.4 with jBOSS 7.1

i have changed my backend db to MS-SQL using the link https://community.jboss.org/wiki/SetUpJBPM54FinalInstallerToUseMSSQLServer2008UsingJTDS

Followed the steps provided by https://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-example

I'm using the following transaction manager,

Unfortunately when i initiate a process from the servlet, i get the following stacktrace,

58:12,868 INFO  [main.java.com.sample.processserver.TaskProcessServlet] (http-localhost-127.0.0.1-8080-2) @@@@@@@@ Start Process + Begin + JBPMAPIUTIL

when i perform the same action again, i get such an exception Bitronix Transaction Manager - cannot open disk journal

Could any provide me guidance ?

Answer 1

So the error is related with the JNDI resource. If you are running in JBoss you shouldn't be using bitronix, you need to use the JBoss Transaction services inside the AS. For that you will need to modify your persistence.xml file and change this property:

To use the jboss one. Then you need to make sure that you have correctly configured the following data source inside jboss: java:jboss/datasources/jbpmDS
