Hi Deepti,

Is it generating the war file and is it deployed in the tomcat ?

jatan

Hi Jatan,

Yes the war file is generated and the project is getting deployed.
The class files have also been generated.
There arent any errors in console either.
However still get 404 error resource not found

You didn't tell us what you did which causes 404 error. What URL did you type?
