# fop configuration

 Hello,   I'm a new user of FOP 0.20.3 I would like to run my first sample simple.fo (set in docs\examples\fo) but unfortunately, it doesn't work. I guess it's a classpath problem because when I write the following instruction on the command line, the error message is: Exeptoin in thread "main" java.lang.NoClassDefFoundError: org:apache/log/format/Formatter at org.apache.fop.apps.Fop.main(Fop.java:16)   below is my complete classpath set: CLASSPATH=C:\tomcat\common\lib\servlet.jar;C:\xalan\bin\xalan.jar;C:\xalan\bin\xercesImpl.jar;C:\xalan\bin\xml-apis.jar;C:\xalan\bin\xalansamples.jar;C:\xalan\bin\xalanservlet.jar;c:\xalan\samples\ApplyXPath;C:\fop\build\fop.jar;C:\fop\lib\avalon-framework-4.0.jar;c:\fop\lib\xalanj1compat.jar;c:\fop\lib\batik.jar;c:\fop\lib\ant.jar   Is something wrong? Is there any problem with xalan classes because I've installed Xalan too?   Thanks a lot for your responses, Cyril.
