Error bad major version at offset=6
I installed RQM 3.0.1 and it's been running fine. Now I want to set up tomcat to run as a service. So I followed the direction at http://publib.boulder.ibm.com/infocenter/clmhelp/v3r0m1/topic/com.ibm.jazz.install.doc/topics/t_run_rqm64_win_service.html. The service is installed and comes up fine. But when I try to login RQM I get the following error: com/microsoft/sqlserver/jdbc/SQLServerDriver) bad major version at offset=6. This sounds like a mismatch of sqlserver driver somewhere. But I can't figure out where. I have only sqljdbc4.jar in server\sqlserver directory. Could somebody please tell me where and what to check? Thanks.

"bad major offset" errors are the JRE's non-intuitive way of informing the end user that you're trying to load a class file that is not compatible with the JRE that is running. In this context, it means you're trying to load a Java6 jar (sqljdbc4.jar) with a Java5 VM (what RQM runs under in a Tomcat deployment).
You need the SQL Server JDBC 2.0 driver, not 3.0 or 4.0. Reference: http://publib.boulder.ibm.com/infocenter/clmhelp/v3r0m1/topic/com.ibm.jazz.install.doc/topics/t_s_server_installation_setup_sql.html Hope that helps. |

Actually, I'm using SQL Server driver 2.0. It includes sqljdbc.jar and sqljdbc4.jar. Your explanation makes sense because I got it to work after I replaced sqljdbc4.jar in sqlserver folder with sqljdbc.jar and set SQLSERVER_JDBC_DRIVER_FILE to point to sqljdbc.jar. To my understanding sqljdbc.jar is for Java5 and sqljdbc4.jar is for Java6. I only have Java6 installed on my machine. How do I force RQM to run under Java6 VM? Thanks.

RQM 3.x will only run with Java5. RQM 4.x will run with Java6. |
I'm having the same problem. We have Java 5, Update 15 on the server as we are installing 3.0.1.3 and are seeing this problem. Has there been a solution to this? I tried to follow the steps listed here and I'm still getting the error.
