Jar files ??????????????????????????????

Please I have some questions about jar files:
1) How can I make a jar executable, for example if I have lot of classes in a java application and I want to create
a jar file that I can run it with java command instead of having lots of classes in the directory,
2) how about if it's not application, it's applet
3) how can I see or extract classes from jar file.

Thanks

Use Jar.exe thats comes with the JDK 1.2, look in "bin" directory.
It doesnt matter if your class is application or applet.
Use a zip-program to open and extract jar-files, eg. WinZip. Use the "show all files" option and point to your jar-file. Jar files is basicly zip files that has been added a manifest. Hope this helps !

hai,

jar cfm samp.jar *.class
in applet tag-
<applet class=samp.class archive="samp.jar" width=500 height=500> </applet>

while extraction give

jar xvf samp.jar
