We are using websphere application server for developing myProject. I came into this project middle of the development process, so i have a doubt about the structure of the project. In Package Explorer of the webspere IDE, always i need to import two folders called myProject where actual code is exist. and second one is XXXDeploy, under which there is folder called META-INF in which there has a file called application.xml. Under the Module tab of the application.xml file we add the myProject.war, also we set some values like database server name under Deployment tab of the application.xml file. Now, my doubt is what is the need of XXXDeploy folder?. In normal eclipse IDE we wont use any such additional folder for the project.
