Hi,
I can't really explain this phenomena but it's a fact.
I've executed the next steps
*
I've removed the mysql_connector.jar and I've modified the log4j.jar
(I've introduced the mysql class in this jar) ==> SAME PROBLEM AS BEFORE
*
I've introduce the path in the java instruction ==> SAME PROBLEM
*
I've deleted the 2 jar ==> SAME PROBLEM ==> log4j.jar exists somewhere
(because the problem was with mysql.jar and no with log4j.jar).
*
I've found all the log4j.jar on my filesystem. One of them was in the
jre directory (I don't know exactly why!).
*
I've removed this jar ==> PROBLEM because log4j.jar not found
*
I've copied log4j.jar in the log4j directory ==> PROBLEM because
mysql.jar not found
*
I've copied mysql.jar in the log4j directory ==> NO PROBLEM
I don't really understand why java don't used the jar specified in the class.
Thanks for your help.
Raoul

Hi,
just to be curious: how can the existence of a user specific
jar file (i.e. other than rt.jar, tools.jar etc.) within some
jre directory influence class loading behaviour, without
being present in some CLASSPATH, -cp or -Xbootclasspath???
Any hint welcome :-)
Thanks and best Regards,
Andreas
