Thanks a lot for Your fast answers! There is no problem when i'm executing query from query browser (Quantum plug-in in Eclipse), but when i want to do that from Java/Tomcat/Struts/iBatis application i have the mentioned exception. What's the difference? I'm not using transaction for executing this query: sqlMapper.update("changeStatus", params); How comes that query is working form query browser and doesn't from application? Should I start with journaling on database or go on with examining my code? Regards P.S. As I assumed this topic doesn't belong to iBatis, so I'd ask the administrator to move it if necessary -- View this message in context: http://www.nabble.com/iBatis-AS-400-journaling-STRJRNPF-tp20189119p20191781.html Sent from the iBATIS - User - Java mailing list archive at Nabble.com.
