Re: Problem with Classpath and/or Eclipse

[Jim Mason <jmason900@xxxxxxxxx>]

Hi Richard.

I don't know what your runtime problem is other than
the obvious.  It sounds like the AS400JDBCDriver ISN'T
in the classpath at the time you try register it with
the driver manager.

1) I assume you do a
Class.forName("com.ibm.as400.access.AS400JDBCDriver")
to force load the class before trying to register
it...

2) verify the classpath is what you want with the java
command:

java -classpath myjar.jar;%classpath%  myclass


I have easily exported the jt400.jar to a directory,
pulled that into Eclipse and created my own jar file
as well.  That works fine.  I assume you are using
Eclipse 2.0x.  1.0x didn't work well for Java
testing..
