[jboss-user] [JBoss jBPM] - Error while trying to connect to Oracle database from jBPM

[b_sathish_1999]

Hello,
I am trying to connect to an Oracle database from jBPM rather than the default in memory database. I have made the necessary configuration changes for that. I created a PAR file out of the process definition. I am trying to deploy the PAR file using the ant DeployProcessToServer task. When I run the build.xml, I get the following error :

Buildfile: C:\jBPMworkspace\jBPMFinTran\build.xml
deployProcess:
     [echo] Deploy the process definition
[deployToServer] deploying par C:\jBPMworkspace\jBPMFinTran\processes\simple.par\simple.par ...

BUILD FAILED

Also, when I start the server I get the following error :

  Please let me know how to get rid of these errors and connect successfully to Oracle database from jBPM
