Dear Pros and Noobs

I am stuck with the Database Connection Pooling problem.
I have created and tested a Database Pooling successfully.
But recently I have faced a problem saying


Could anyone help me to solve the problem please. Before I post this, I have tried to find the answer in the Internet and coderanch but the solution didn't work for mine.

Context.xml
I put the context.xml in the C:\Users\Bio\.netbeans\6.9\apache-tomcat-6.0.26_base\conf folder.


ProfileController.java
In ProfileController.java, I open and close the Database Connection once.
The first connection I use it to retrieve the profile information in line 83.
The second connection I use it to retrieve the user's profile comments in line 99


Thank you guys.

God Bless
