When i use File f1 = new File(“test.XML”); it create the file in the tomcat’s Bin folder. The file must be created in the Project while Running in both Tomcat and Jboss EAP 6.

You can get the real path of the web application using the servlet context:

new File( servletContext.getRealPath( "/text.XML" ) );

Note: if you’re running tomcat/jboss on Linux, you’ll probably have to give permission to write in the webapp folder though, which is most likely forbidden by default.

Quoting from Servlet API docs of ServletContext.getRealPath():

Returns a String containing the real path for a given virtual path.
For example, the path “/index.html” returns the absolute file path on
the server’s filesystem would be served by a request for
“http://host/contextPath/index.html”, where contextPath is the context
path of this ServletContext..
