Subject RE: Jasper Error wrong version of Object.class (48.0 , should be 47.0)
Date Tue, 01 Apr 2003 20:26:39 GMT

Make sure you're using:

- The JDK (not JRE)
- The right version of the JDK (preferably the latest stable version)
- An OS that has the patches required for the JDK, if any

This was a known bug in JDK 1.4.0b92 or something like that: search the
BugParade on
