Assume there is a dynamic project.
I have a file e.g. FileX under the Project’s directory i.e. outside of all source files etc.
E.g. ProjectA
If I export as WAR the ProjectA.war and open it I see of course the WEB-INF etc.
How can I include FileX in this export process so that FileX is included in the ProjectA dir along with WEB-INF etc?
You can have eclipse generate the equivalent ant file to generate the WAR, you can them modify that ant file to include what you want.
This can be done by right click on the project > export > General > Ant buildfiles. Make sure you uncheck the ‘use eclipse compiler’ if you want the build file to be usable from outside of eclipse.
