org.xml.sax.SAXParseException: </body> does not close tag <HR>. at org.apache.xmlbeans.impl.piccolo.xml.Piccolo.reportFatalError

I run a dynamic web application via Eclipse and I think that the Tomcat works fine under it, I browsed the servlet from the tomcat server in the Eclipse, the welcome page of the servlet appeared but when I try to access to its differeent functions, I keep getting an error like this:

message

Please, what's the problem? How can I resolve it? I searched in the net about this problem but have not found a solution that works for me.

Thanks for your prompt answer that I really really need.

Look at the very bottom of the trace. The root cause of the exception is the most important part.

The <HR> is not XML well formed. In XML you need to close all tags. Replace <HR> by <hr/>.

Either your deployment is incorrect or the connection URL is wrong. If the servlet is running, you aren't pointing to it properly.
