Answer 1

Today I was trouble shooting a jsp page that uses JDBC posted on a TOMCAT server. I was have the same exception as you guys described but found a work around for my program.
I as reading data from my db into the jsp page (into a table and some drop down menus). The error screen would pop up randomly as I accessed the page. If I refreshed page quickly it would cause the error to happen more often it seemed.
The fix was i used the "finally" statement to close every instance of ResultSet and Statement.
Before I use simply:
rs.close();
st.close();
rs = null;
st = null;
I have 2 seperate parts on jsp page where I accessed db. Once I put in the finally it worked. Here is the code I used:
try
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
     String sourceURL = new String("jdbc:odbc:D2TEST");
     Connection dbconn = DriverManager.getConnection(sourceURL);
     st = dbconn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
     rs = st.executeQuery("SELECT * FROM CIS_REFERENCE");
     while (rs.next())
          {     minute = rs.getInt("PERIOD");
               onoff = rs.getInt("PONOFF");
     finally {
          if (rs != null) {
               try {
                    rs.close();
               catch (SQLException sqle)
                    System.out.println(sqle.toString());
          if (st != null) {
               try {
                    st.close();
               catch (SQLException sqle)
                    System.out.println(sqle.toString());
Sorry bout the spacing I just cut and paste.
Hope this helps
