I create a persisstance object, called LogInformation, I want the createBy and lastUpdateBy value is from session that I create using JSP. I use WebWork to do a save action. This is my code. I got dispose error when try to execute it.

If I remove the line of setCreateBy and setLastUpdateBy, the save execution to database is run well. but the value is null.

anyone can help?
