problem related to MANIFEST.MF in jar

Question

I have created jar in folder /usr/local/bin/niidle.jar.

And I have cerated MANIFEST.MF in jar as follows:

Manifest-Version: 1.0
Main-Class: com.ensarm.         


        

Answer 1

Line niidle.jar/lib/hector-0.6.0-17.jar is confusing. Is niidle.jar directory or file? I'd suggest you to post your full manifest, directory structure, command line you are using and current working directory.

But generally you should write in your manifest: Class-Path: hector-0.6.0-17.jar

then put all jars in one directory. Let's call it foo. Now open command prompt, go to foo and run

java -jar niidle.jar args...

And I believe that everything will work. Then if you wish play with location of your jars.

Answer 2

java -cp /Projects/EnwelibDatedOct13/Niidle/lib/hector-0.6.0-17.jar -jar /usr/local/bin/niidle.jar arguments.....

You can't use the -cp switch together with the -jar switch.

From http://mindprod.com/jgloss/classpath.html:

If you use the -jar option, java.exe ignores the classpath. It will only look in that jar!! Try using the manifest Class-Path instead to get Java to look in auxiliary jars

And I have added this 'hector-0.6.0-17.jar' in niidle.jar folder as follows:

To my knowledge, you can't nest .jar files this way.

Since you have Class-Path: hector-0.6.0-17.jar you need to have the needle.jar and the hector-0.6.0-17.jar side by side and run niidle.jar from their common directory (using the -jar switch if you like).

For setting up "jars within jars" take a look at this question:
