 Nested Exception: java.lang.RuntimeException: Failed to Generate Wrapper Class Hi all, I've created a MySQL datasource but when I make it the source for a EJB I get the error above. I think the error occurs during deployment, rather than while building. When I use a WebLogic-supplied, PointBase datasource the deployment works OK, so it must be the way I've configured/built my datasource. Any areas I should check before I go further? I've listed below some messages I get and these are followed by the remainder of the error message. Thanks in advance, Roy. some messages I get during deploy are: ------------------------------------------------------------------------------------------------------- BEA-001068 18-Nov-2003 17:08:25 o'clo Info JDBC Connection for pool "MySQLPool" created.

| Re: Nested Exception: java.lang.RuntimeException: Failed to Generate Wrapper Class Hi, I am getting a similar error that the one you had some time ago and I was wondering if you had fixed it eventually. I am running wls 9.1 and mysql 4.1.18 with InnoDb as engine for the tables. This is the stack trace I got. Code: java.sql.SQLException: Cannot obtain connection: driverURL = jdbc:weblogic:pool:
xxxDS, props = {EmulateTwoPhaseCommit=false, connectionPoolID=xxxDS, jdbcTxDataS
ource=true, LoggingLastResource=false, dataSourceName=xxxDS}.

Anaway, I'll keep trying in wls and mysql forums. Thank you, Best regards |
