You may check the following things What version of JRE you are using ? because Jaguar 3.5 supported 1.1.8 or below , it was not compatible with 1.2.2 So if you have multiple version of the JDK on your box , the class files may seem to work because they are using a newer version. Is tree.xml located in a folder that is visible to Jaguar. If you made any classpath changes and have not restarted the Jag server , try doing that , because Jaguar loads classes when it starts and does not recognize class path changes until it is restarted.
