How are you building your runnable jar?  Are you using an Ant build script?  Or 
using the Eclipse export wizard?

As Nick said earlier, this is really a procedural question that is better suited 
to the Eclipse Forums.  However, this is something that I am currently able to 
do without issue and I am doing it with POI.  I use plug-ins and the export 

I recently sent a post to this distro about how to create a plug-in from the POI 
jars.  You need to do that and then re-create your project as a plug-in.

To do this, create new project using the New Project Wizard, right click > New > 

Then go down to the Plug-in Development node, expand it and select "Plug-in 

On the first page of the subsequent wizard give your project a name (something 
like com.mycompany.project) and a version number.  Click next.

On the next page you can specify the provider and a name.  In the "Options" 
section below the naming stuff, there is a check box for "This plug-in will make 
contributions to the UI" - uncheck that if it is checked.  Next, select "no" 
under the "would like to create a rich client application?". Click "Finish".

Expand your new project and go the META-INF/MANIFEST.MF.  Click on the 
Dependency tab in the Manifest Editor.  On the left you can add plug-in 
dependencies, so click 'Add' and start typing the name of your POI plug-in.  
Select your project and click 'Ok'. Save the manifest.  Now you can import your 

Finally, you should now be able to right click on your project and run the 
Export wizard to create a runnable jar file.

This is a medium level overview, there is more to understand about plug-in 
development but I think this gets you most of the way there.

sourceforge) , using extract runnable jar .. i am getting duplicate entries
for poi classes while creating extract runnable jar . but not able to
decipher the reason , it works in Eclipse , but not when i create runnable
jar . Yes Eclipse forum , yes .. meanwhile any poi developer came across
similar problem ?

HSSFSheet . HSSFRow class are there in the created runnable  jar file , is
there any way to see the methos inside the jar ?
