Hi All,
I am facing a problem in my application.
I wanted to create a stand alone application that needs the weblogic.jar in its class path to run
I had created a self executable jar file for this.  
weblogic.jar file is usually located at C:/bea/weblogic81/server/lib/ folder
I created a manifest file as follows

Manifest-Version: 1.0
Main-Class: com.Starter
Class-Path: file:///C:/bea/weblogic81/server/lib/weblogic.jar


and i use the following command to jar it

jar cfm myapplication.jar manifest.mf com/

Manifest file in the jar file is as follows
Manifest-Version: 1.0
Created-By: 1.4.1_02-er (Sun Microsystems Inc.)
Main-Class: com.Starter

and the application fails to work ,
can u please help me in this regard ?
Thanks in advance  :-)

> Class-Path: file:///C:/bea/weblogic81/server/lib/weblogic.jar

this need to include the relative location of jar.
eg. if weblogic.jar is in same directory:

Class-Path: weblogic.jar

Hi ajithprabhakar,

Try to run your application using the following command line:
  java -classpath C:\bea\weblogic81\server\lib\weblogic.jar   -jar myapplication.jar

you need to use the Class-Path as you are, you just need to supply the *relative* location of the jar.

hi there,
i am aware that i can use both the ways, but what i want to do is to set a path to a jar file which is not in the same directory , that means i want to give absolute path in my self executable jar file.
But for the relative location the jar to which my class path points should be a part of the new archive that i am creating right ?

you can't.
You'll need to install any required jars as extensions (in the 'ext' directory) if you do not specifiy them using Class-Path:
Or don't use a executable jar of course.

Not sure what you mean by 'creating'?
It should be pointing to the location of any other jars/directories that are required by the executable jar.
