Any Possibility To Extract Contents of a JAR File

[AmeyDeshpande]

Hello

Is there Any Possibility To Extract Contents of a JAR File . i.e class files with proper names.

Hi AmeyDeshpande,
If your jar file is an obfuscated one,then i suppose you cant extract class files with proper names.But if not obfuscated you can extract it with the correct file names.

Thanks

Thanks


I knew IF the Jar file is obfuscated then we cannot get
but there may be some thing that we can do it ..
Or we can make that obfuscated jar in to Simple JAR file ....
OR there may be some tool from which we can Extracts contents of obfuscated jar ...

Hi amey,


Obfuscation is one of the security policies.
The only thing u can do is to unzip the jar file to a new folder. There u will get the obfuscated class files & resource files.
U can use a decompiler to read the obfuscated class files. But the methods, variables & class files will be in there obfuscated name itself.You can't do anything for this.

Any way a small question Why do u want to read an obfuscated class file

Hi Amey,
I am not exactly clear what you want to do.
With JDK1.5 there are a collection of classes that
handle jar files and enable you to read and write them.
It may be possible to find the source for these routines
and port them to J2ME.
If I remember correctly, jar is like tar but the entry is
compressed. It should not be too difficult to write
a routine to extract the headers.
