When I execute a .jnlp file in WINDOWS somentimes JAVA create a set of directories where put relative files. For example if I run .jnlp file, after I have a DIR on C:\ and the dir is C:\MyDir. I want that JAVA works with a different basedir, specifically for the previuos example I want E:\MyDir. I think that is logic to choose a basedir but after various searches I can't do this job. Is there a way to do this? In the control panel of Java I have only control for temp files. Thanks.
