Hi,       I am including xerces.jar in classpath and when a jsp page is loaded:      - for the first time, the following error appears:                          java.lang.ExceptionInInitializerError - in the next times, another error is displayed, another error is displayed: java.lang.NoClassDefFoundError: <path/class name>   Does someone know this problem?   Thank you in advance! Elisabete.
