When i created a new process instance I got the following exception on the broswer, org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException: Could not commit session or rollback

root cause is available in the JBoss Web/2.1.3.GA logs. I didn't find any record in PROCESSINSTANCEINFO table, but I saw a new instance has been created in the web page. Is this just a problem in the demo? or it's a transaction control bug in jbpm5.1? I resolve this problem by extend the length of processinstancebytearray colum in table PROCESSINSTANCEINFO from 255 to 500.But I still worry about this is a bug relate to jbpm core part.Could any one tell me about your experence in the project implementation, is this a serious problem? Another question is , if i wanna integrate the jbpm to my project, is there  a stable database script that could  create the tables jbpm require on db2 v9?Thanks. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/632675#632675] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
