need help on mysql connection

[pavani duggireddy]

Hi,

I am using Mysql
4.1.15(mysql-standard-4.1.15-sun-solaris2.8-sparc-64bit)on
a solaris machine. My application is running on
weblogic8.1 sp2. 

I have configured the mysql connection pool on
weblogic and tested from configuration wizard. I am
facing issues when connecting to Mysql pool from my
application.

The error message is as follows

java.lang.NoClassDefFoundError:
