NoClassDefFoundError

[Chidananda Sulur]

Hi,
I have written a sample Java client to access a connection from a connection pool. This is using the JDBC/RMI type-2 driver for Oracle. I have defined the connection pool & the datasource in the weblogic.properties file. The program uses JNDI to do the lookup. Though the program compiles, it is giving a run-time error. I've pasted the error code below. Basically, it is stating that it's not able to find com/sun/java/util/collections/map package.
Does anyone have an idea about the cause for this run-time error? Please help.
Regards,
Chidananda.

The Map interface that your program can't find should be found in weblogicaux.jar, the full path of which should be on your CLASSPATH.
Check that the correct weblogic jar files are correctly placed on your classpath.
