I am getting java.sql.SQLException error and don't know where to turn.

Below is the stacktrace:-

After researching and asking around a lot...I got feedback that I am getting
the error because even after the connection has been closed i am calling the
resultset. However, I am using iBatis + Spring across whole application and
dont deal with ResultSet.

My Sample code is below:

this.setSqlMapClientTemplate(getSqlTempl());
getSqlMapClientTemplate().queryForList("authentication.isUserDAO", parmMap);
this.setSqlMapClientTemplate(getSqlTemplDW());
List results = (List) parmMap.get("Result0");

I simply call the SP with parameters and get a resultSet back. I saw a
ticket opened in JIRA for iBatis that had similar error, however, I am not
using proxyConnection. https://issues.apache.org/jira/browse/IBATIS-539

Has anyone seen this type of message before ? any ideas/pointers?
