Hi to all!
I use Tomcat together with mysql to store my data.
I wrote an servlet at school that uses an Oracle Database to store and
retrieve data. It worked fine. So I wanted to use this servlet at home too.
I changed the JDBC driver but now i get in the tomcat.log file an exception.
The source of the exception is, that i cn't connect to my database. in my
tomcat.log - file i found this entry:
2001-04-30 10:50:05 - Ctx( /examples ): Exception in: R( /examples +
/servlet/Navigation + null) - java.lang.NoClassDefFoundError:

Before i had some other errors. I change the classpath that the mysql-jdbc
driver is also in it. And now the error mentioned above occours.
Is this a problem of my classpath and why does the exception writes:
org/gjt/mm/my.... an not org.gjt.mm.my.....?
I know this is not a problem of tomcat, but I think many of you use the
mysql database with java.
Perhaps someone can help me.
Thanks in advance,
Robert
