Avoid conversion of Java CAB to ZIP on i

By oren ·
We are installing Java classes by placing them in signed CAB files. When these CAB files are installed, IE opens the CAB _to the disk_, then creates a ZIP file from the resulting files. This ZIP file is what is finally installed in the system.

Itis obvious why this is done - Java requires random access to the ZIP/JAR file, and CAB files do not provide such access (that's why they are 30% smaller). What is less clear is why IE goes to the disk when it does the conversion. There are _many_ class files in a JAR file, in a deep directory tree, and this is _slow_.

Has anyone found a way to avoid this problem? For example, using nested OSD files to place a single JAR file inside the CAB file, or something along these lines?

Well, you are right, of course. In fact it has been such a long time I'm now working in a different company :-) We have never managed to solve the problem, BTW.

Please clarify as to you want to avoid the problem of IE going to the disk when it does conversion or avoid installing the classes in JAR? For the former, you can direct the question to Microsoft, they should be able to provide you the answer. For the latter, direct it the Suns Microsystem.

We wanted to avoid the excessive disk activity, which took ages. Sure we could ask Microsoft - we did - but form some strange reason, it doesn't seem as if they are very helpful when it comes to improving Java performance in IE :-)
