hamsterdancer [https://community.jboss.org/people/hamsterdancer] created the discussion "jBPM5.3 with postgres and hibernates mapping of processInstanceByteArray" To view the discussion, visit: https://community.jboss.org/message/741976#741976 -------------------------------------------------------------- Hi there. I just wanted to use jBPM5.3 with postgres and ran into some trouble I didn't unterstand instantely but was easy to fix (after finding its source^^). After I've changed everything I just got the nice output in the log below. It says something about a bad type for the processinstancebytearray... The column is defined in the ProcessInstanceInfo.hbm.xml in the db folder of the jbpm-installer with an user defined data type called org.jbpm.persistence.processinstance.BlobUserType. I was not able to find it in the sources. But what I found was another file in the jpa part https://github.com/droolsjbpm/jbpm/blob/5.3.x/jbpm-persistence-jpa/src/ma... https://github.com/droolsjbpm/jbpm/blob/5.3.x/jbpm-persistence-jpa/src/ma... Here the column is defined different to the file of the installer. So it was just needed to replace the line and everything works fine. 13:42:30,417 ERROR [org.hibernate.util.JDBCExceptionReporter] (http-localhost-127.0.0.1-8080-1) ERROR: column "processinstancebytearray" is of type oid but expression is of type bytea   Hinweis: You will need to rewrite or cast the expression.   Position: 149 13:42:30,434 ERROR
