Recently, I came across a problem when updating a jar file.
How does one update a jar file with a class file using a particular packaging?
So you have a jar file named
foo.jar with two elements in it, a package (
fooPackage) containing multiple class files and your manifest.
You also have a class named
bar.class that is packaged by
fooPackage (*see bottom).
Do you think this will package it correctly?
>> jar uf foo.jar bar.class
No. Not really. It adds
foo.jar without a hitch, but does not keep your packaging path. Instead, it adds
foo.jar, but outside the package path you want.
If this was a stand-alone java application, this will not reflect your changes when running.
With this being said, I turned to a few external solutions to solve this problem.
After hours of frustration with a few programs (ie: DJ Java Decompiler), I finally ended up using WinRAR that did the trick and placed the
bar.class in the correct package path (graphically).
*Note: When I say packaged by
fooPackage I mean that the .java equivalent of
bar.class has the code:
