I am trying to build an App that reads Excel files. I'm using Eclipse 3.0 and the POI API. Everything works when I launch from within Eclipse, but once I export to an executable jar and try to run it the class that uses POI does not seem to work.
I have the POI jar included in my libraries for this project and have played around with the order in the Order and Export TAB in Project Properties menu.
Any help would be great!
distressed intern.

Not a build tool issue. Moved to the IDEs forum.

John,
Welcome to JavaRanch!
The jar export is just exporting your code. You still need to have poi.jar in your classpath.

First time using classpath. I have poi.jar in my class bath. But when I try to open the Excel sheet after starting my jar I get "NoClassDefFoundError" and then it lists the fisrt class I try to use in my code.
my comand line looks like so and a few variations
java -classpath /poi.jar; -jar myjar.jar
java -classpath C:/db/poi.jar; -jar myjar.jar
java -classpath C:\db\poi.jar; -jar myjar.jar
It runs fine in Eclipse, what can I be doing wrong?

Since it works in Eclipse, this is more of a command line question than an IDEs one. I'll move the question to Java In General for you.
