Use your custom ClassLoader!

I have got the custom ClassLoader for a jar and for a file.I am able to load all classes in a jar or single class file in standalone mode ...but when i use the methods from a jsp the loading process is failing due to dependencies in those classes.

When I use the methods from a jsp .I get some

java.lang.NoClassDefFoundError: javax/mail/MessagingException for the first class

I dont have the source of the class file thats why I am not able analyze how the class is dependent on the above error.I have put every jar file in CLASSPATH but its still the same result with a jsp but in a stand alone mode its working perfectly fine.

Please help in this regard.

Bye

Ravi
