how to extract

Hi everybody!

how to extract the API class files from a jar file.
When we download the API of servlet it comes in a jar file. I don't know how to extract it and install it. Thanks in advance.

To extract all files in a jar, use this command jar xvf jarname.jar.
Use jar -help for more options.

HI NAREN!

THANKS FOR YOUR REPLY. BUT ACCORDING TO MY KNOWLEDGE WINZIP IS USED TO UNZIP A FILE NOT A JAR FILE.

Winzip can unzip jar files. A jar file is just a mutant hybrid between a tar file and a zip file. Winzip can also open tar files.

You don't need to unzip servlet.jar to use the class files it contains. The class path just needs "servlet.jar" in it.
