Loading File (not-image) from JAR ..

Question

Here s the jar structure i have:
myapp.jar:
-- package1:
-- -- *.class
-- file.ext
-- image.gif
How come i cant create inst. of File with the new File(with getClass().getResource("/file.ext").getFile()); ??
There s no problem with loading the image, but the other file always fails .. it says that the path is wrong (i guess it s beacause file:\D:myapp.jar!\file.ext is not a 'real' file-system path). How can i load a file from jar, without using getResourdeStream, without any temp files .. I would really appreciate some help. Thanks in advance.

Answer 1

i need an inst. of the File class pointing to tht file.The only file mentioned in your OP is D:myapp.jar and you can get the corresponding File object by parsing the string returned by getFile(). Notice it will still only be a valid file if getResource() returns a file: URL - something that cannot be guaranteed.
The point bears repeating, perhaps: D:myapp.jar!\file.ext is not a file. It is a resource (accessible via an input stream). Because it is not a file there is not - and never will be - any File object which represents its name.
I was ( and I m still) thinking tht it could be some classpath-and-sh**t problem.The classpath has a bearing on where a resource will be looked for, but says nothing at all about what is looked for. In this case you simply cannot "load" the file (whatever "load" means) because there is no file to load.
Finally, it is quite possible that you can do whatever it is that you are trying to do. But you have yet to say what that is: not how you want to do it (by instantiating a File, not by creating a temporary file or using an input stream), but what you want to do.
