This error is killing me! I wrote a simple app with xml database & appache tomcat. I worked fine, till I tried to zip the workspace while it was open. After that anytime I try to create tomcat server promptly I get this error : ClassNotFoundException: org.apache.xml.serializer.TreeWalker . So I left this. Now I was working on xmlspy, trying to generate a pdf file using tomcat FO engine. I installed new tomcat & pointed to this in the xmlspy. Now when I try to run fo in xmlspy I get the following error. Note: The serializer.jar & xalan jar files are already in lib folder. log4j:WARN No appenders could be found for logger (org.apache.fop.util.ContentHandlerFactoryRegistry).log4j:WARN Please initialize the log4j system properly.log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/xml/serializer/TreeWalker at org.apache.xalan.processor.TransformerFactoryImpl.newTransformer(TransformerFactoryImpl.java:823) at org.apache.fop.cli.InputHandler.transformTo(InputHandler.java:278) at org.apache.fop.cli.InputHandler.renderTo(InputHandler.java:130) at org.apache.fop.cli.Main.startFOP(Main.java:174) at org.apache.fop.cli.Main.main(Main.java:205)Caused by: java.lang.ClassNotFoundException: org.apache.xml.serializer.TreeWalker at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) ... 5 more
