Please help me to solve the problem.

Can anyone please help me on my error?

Thanks in advance

This doesn't sound like a Tomcat issue to me.
Have you checked with RoseIndia to see if this is a known issue on their end?

Yes i have posted the same issue with roseindia.net also. I am yet to get a reply. When i was searching into google for any such similar issues. I found that using an outdated version of commons collections JAR in the classpath may be the problem. Can you provide me the steps to update the latest collections JAR file and also to where and how upload it in my computer. I am a beginner to java and just learning coding by myself
