java.lang.NoClassDefFoundError: java/util/LinkedHashMap in WSAD
Hi ,
I am using MySql 5 as the database and this is the error I am getting when I am trying to run my program on WSAD .
I did set the classpath right .Both to j2se1.4 as well as MySqlJ Connector .
It is loading the driver but its not gettting through to Connection
Can anyone tell me what the problem is ?
