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:
