Connection Pool Leak

Question

Hello All,
I seem to have sprung a leak and cannot work out what is going wrong.
I return a result set from a class to jsp, I cannot close this resultset before it is passed back, however I do close it in the jsp after use. Do I actually have two connections open here or one, i.e. one in the jsp and one in the class, if so that may be the problem.
The other problem I have is that I have set Tomcat up to RemoveAbandoned connections after 15 seconds. I had expected the application to recover after 15 seconds, but it does not, instead the Tomcat console reports an error:
Open connection failure: Communication failure during handshake. Is there a server running on localhost:3306?
My current answer to this is, 'there was, but I dont know where it went :-)"
Any help appreciated

Answer 1

Ok, its come back to life, though it took a couple of minutes, not the 15 seconds I had banked on, this still leaves the problem of how to close all connections, perhaps I should explain what I have:
Class ReturnResult: contains code to establish connection and returns resultset. This class closes both the resultSet and connection prior to passing back the data.
Class Session: handles requests from jspPages that require session data, this class extends ReturnResult. I have a method in here called testRS that uses the following:
ResultSet rsGetText;
rsGetText = getRS("select * from pagetext");
return rsGetText;
getRS is a method of ReturnResult.
I cannot close the resultSet in the testRS method, if I do the data is not passed back to the JSP, I think this may be where the probelm lies.
In my JSP I have:
ResultSet rs = sUser.testRS();
     while (rs.next())
          out.println(rs.getString("english"));
     rs.close();
so the resultset is closed here.
If I cannot close in the testRS before passing the data back, is it possible to use a seperate method to close the resultset from the jsp??
Thanks,
