XLMReader Spring Security Error

[Darkcloud]

Hello,

This is my first Thread, I hope you could help me with my error.

I Built a Spring security Project to use it on an Unix /Tomcat 5.5 machine. It worked great for a period of a year or so; but the last week it started to fail with the following stacktrace:

java.lang.RuntimeException: Unable to create XMLReader

Please use [ code][/code ] tags when posting code. Also have you read the stacktrace?

java.lang.ClassNotFoundException: org/apache/crimson/parser/XMLReaderImpl

You are missing a library, so probablyl something changed, a library updated, jdk change or something else.
