There's obviously something going wrong in the XML parser. Here's a list of things that come to my mind:
- Check if the standard FOP examples work correctly. If yes, there might be a problem with your fo file. - Open the fo in one or two XML editors to see if it gets parsed correctly. - Search the Internet for similar the same NPE. - Switch your XML parser (even if you just use another version of the same) - Get the source code of the XML parser and try to track down the cause of the exception using the line numbers in the stacktrace. - Try to set everything up in your IDE and set an exception breakpoint for java.lang.NullPointerException. I hope this helps. On 23.04.2002 06:41:23 Patrick Lanphier wrote: > How does one debug this?
