Convert file located in OSGi Bundle to IFile

I have an installed bundle (org.osgi.framework.Bundle) in my running eclipse. There is a file in this bundle. I have the path to the file and i can represent this file by an URL (java.net.URL) by using URL url = bundle.getEntry("/folder/file").

Is there a way to get a handle of this file of type IFile (org.eclipse.core.resources.IFile)?

I need a reference of the file located in the installed osgi bundle of type IFile. But I don't want to copy the file temporary on my local disk (like workspace).

Thanks in advance!

If you have an eclipse plugin / editor or something like this try:

//get the workspace
IWorkspace workspace= ResourcesPlugin.getWorkspace();

//create the path to the file
IPath location= new Path(yourURL.getPath());

//try to get the IFile (returns null if it could not be found in the workspace)
IFile file= workspace.getRoot().getFileForLocation(location);

if (file == null) {
    //not found in the workspace, get the IFileStore (external files)
    IFileStore fileStore = EFS.getLocalFileSystem().getStore(location);
    return fileStore;
} else {
    // file found, return it
    return file;
}

Helpfull could be also:

url = FileLocator.toFileURL(yourURL);

and/or

URL resolvedUrl = FileLocator.resolve(url);

After this you can create the input for your editor (I think you want to use it there?)

Object file = myGetFile();
IEditorInput input;
if (file instanceof IFile) {
    input = new FileEditorInput((IFile)file);
else {
    if (file instanceof IFileStore) {
        input = new FileStoreEditorInput((IFileStore)file);
    } else {
       throw new MyException("file is null, not found");
    }
}

I hope this will help you.

It's difficult. An IFile represents an actual file rather than an entry in an archive. You would need to build an Eclipse FileSystem (EFS) representation for the archive, but that's likely to be a lot of work.

What are you trying to achieve? There's probably something you can do that is much simpler.
