I am trying to call a method on server-side implemented by Java RMI. This method will open, read and do some data manipulation in the excel spreadsheet.

Workbook wb = WorkbookFactory.create(inp);

This is the code which I get the following exception. inp is a InputStream with specified filepath.

Exception: java.rmi.ServerError: Error occurred in server thread; nested exception is: java.lang.NoClassDefFoundError: org/apache/poi/ss/usermodel/WorkbookFacory

I did also try to call this method locally, which gave no error.

Now, Server and Client are both running on the same machine(localhost).

    On the server side, did you forget to add the JAR file that contains the POI classes to your classpath? `NoClassDefFoundError` (almost) always means that there's something missing from your classpath. – Jesper Feb 01 '11 at 16:21

Add the POI classes to your server's classpath. Just because the client and server are running on the same machine doesn't mean that both share a common classpath.
