Find where the org.apache . . . HSSFW class is, and where it is supposed to be, then make sure those two locations are the same!

[S Shehab]

actually this class is inside poi-3.1-FINAL-20080629.jar and this lib is included in the classpath while i'm creating the exe file with jsmooth.

I need to understand you correct...

Are you creating an *.exe file or an Excel (*.xls) file??

[Rene Larsen]

Have you added the hole needed classpath to jsmooth (see 3.3. Defining the Java Application parameters)??

Thanks Rene for your support , i fixed the issue by making lib folder contains all the external libs plus a jar contains all my applicaiton classes then in the jsmooth in the classpath area i choosed all of them them , then it worked fine ..
