Looks like you have not defined your web.xml file as per the DTD. When xerces parses this file it is checking that each element is as it should be based on the DTD. Hava a look at the DTD and check you have defined web.xml as it is required.

Thank you Paul Sturrock for replying

But in this example i am not validating data...

I am pasting complete code here if anyone knows the where i made mistake please guide me to resolve that error

Main sevlet class



Utility class used for extracting data from XMl file placed inside class folder inside WEB-INF



I am storing this two class files and EventLog.xml files in webapps\examples\WEB-INF\classes

After writing URL-Mapping i web.xml..i tryed to invoke servlet by entering URL in Browser http://localhost:8080/examples/readXML

But immediatly tomcat gets shutdown....If anyone trace out where i made mistake from above code then please guide me in resolving this issue...or else if you know any tutorials link for "SERVLET & reading XML" please post that here

Where did you make your mistake? It was assuming that the code you posted had anything to do with the problem. If you look at the stack trace you posted, you don't see ReadCompleteErrorReport anywhere in it, do you? So ReadCompleteErrorReport has nothing to do with the problem.

If you look a little closer you see methods with names like "ContextConfig.start" and "ContainerBase.start" and "Catalina.start". It's pretty clear that Tomcat is just starting up, and failing to parse your web.xml file because (as Paul Sturrock already said) it isn't valid according to the DTD.
