Java Forum / General / March 2008executing my application outside the IDE does not work
Hello I have application code that runs fine when executed from inside Eclipse IDE. However when I make a jar "myApp.jar" out of it then the jar does not run. If I however remove a certain object of a certain class C from my code and generates a new "myApp.jar", then the new jar runs fine aswell. The class C which I remove from the code to make it work is located in an external jar "x.jar". Inside the IDE, I have included x.jar in the buildpath of the project. My thought is that the class C is not found in runtime when executing "myApp.jar". Where should I put the x.jar for the JRE to find when executing myApp.jar? marcussilfver@gmail.com wrote in news:d6ad2e8f-d687-4048-8f22-44746f7cd069 @t54g2000hsg.googlegroups.com: > Hello > I have application code that runs fine when executed from inside [quoted text clipped - 13 lines] > Where should I put the x.jar for the JRE to find when executing > myApp.jar?

The classpath will be completely ignored due to the -jar option. <http://java.sun.com/javase/6/docs/technotes/tools/solaris/java.html> > When you use this option [-jar], the JAR file is the source of all user classes, > and other user class path settings are ignored. The answer is the Class-Path manifest attribute <http://java.sun.com/j2se/1.5.0/docs/guide/jar/jar.html#Manifest%20Specification> Place the library JAR in the same directory as the application JAR, or a subdirectory, and reference it from the manifest of the application JAR.

I got it working now! regards Marcus On Wed, 26 Mar 2008 03:44:35 -0700, marcussilfver wrote: > Hello > I have application code that runs fine when executed from inside Eclipse [quoted text clipped - 12 lines] > Where should I put the x.jar for the JRE to find when executing > myApp.jar? Do a search for jar mainifest. That should tell you how to include x.jar in the classpath and make your jar file double clickable. I'm surprised Eclipse doesn't do this for you, or maybe it does but you aren't packaging it correctly after. For example, taking a similar approach as you have in Netbeans will create myApp.jar (horrible name) and put it in dist/. It will also put dependencies in the relative directory lib/, that is, dist/lib/. You can then copy the contents of dist/ anywhere and it will run. Check out what is in bin/ in Eclipse.

See http://mindprod.com/jgloss/ant.html You might have a look at some of my jars http://mindprod.com/products.html to see the structure. Look inside your jars to make sure all the class files are there and they are named correctly, and resources are present, and the manifest is correctly built.
