Hi, I'm new to the list. I don't have any clue why this is happening to me. I've spent the past 4 hours trying to figure this out. I stumbled onto a similar error message in the archives here, and it helped me realize I needed to add the classpaths, but I'm still having the error. I'm using the latest version of FOP, with J2SDK 1.4.
C:\xsl\build>java -cp c:\xsl\libs\ant.jar;c:\xsl\libs\avalon-framework-4.0.jar;c:\xsl\lib\batik.jar;c:\xsl\lib\logkit-1.0.jar;c:\xsl\lib\xalan-2.0.0.jar;c:\xsl\lib\xerces-1.2.3.jar;c:\xsl\build\fop.jar -jar fop.jar -xml xmlfoRef.xml -xsl xml2pdf.xsl -pdf output.pdf Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log/format/Formatter at org.apache.fop.apps.Fop.main(Fop.java:16) I just don't get it, and I'm on the verge of going postal. Thanx in advance for all help, guidance, or suggestions. BTW, who do I send a message to about the FOP website and documentation seriously needing to give workable examples of how to run the program? It quite misled me and I nearly gave up on it (but couldn't find another free XSL-FO renderer as an alternative so I had to return to this stressful thing).
