I have a ZIP archive that's embedded inside a larger file. I know the archive's starting offset within the larger file and its length.

Are there any Java libraries that would enable me to directly read the files contained within the archive? I am thinking along the lines of ZipFile.getInputStream(). Unfortunately, ZipFile doesn't work for this use case since its constructors require a standalone ZIP file.

For performance reasons, I cannot copy the ZIP achive into a separate file before opening it.

edit: Just to be clear, I do have random access to the file.
