Hi All,

My program compiled successfully and i crested directory structure for weblogic and i put the class file in classes directory.I created .war file.I deployed the war file,it
deployed succesfully.


I am invoking servlet by using
http:\\localhost:7001\context-root\servletname.

I am getting the following error
