Where is web.xml in Eclipse Dynamic Web Project
When you create a Dynamic Web Project you have the option to automatically create the web.xml file. If you don't mark that, the eclipse doesn't create it...
So, you have to add a new web.xml file in the WEB-INF folder.
To add a web.xml click on Next -> Next instead of Finish. You will find it on the final screen of the wizard.
you can do it by Dynamic Web Project –> RightClick –> Java EE Tools –> Generate Deployment Descriptor Stub.
