Prepared statement not releasing from access db

Question

Hello all,
I have several prepared statements like the following:
public void storeUpdate(String userId,String ws,String wm,String wl,String wx,String wxx,String bs,String bm,String bl,String bx,String bxx, String tq, String tp,Timestamp ts)
     String updatePurchase = "UPDATE store SET smallWhite=?,medWhite=?,lrgWhite=?,xlrgWhite=?,xxlrgWhite=?,smallBlue=?,medBlue=?,lrgBlue=?,xlrgBlue=?,xxlrgBlue=?,totalQty=?,totalPrice=?,ot=? WHERE playerNo='"+userId+"'";
     try{
         Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
         objConn = java.sql.DriverManager.getConnection("jdbc:odbc:myDB","","");
         PreparedStatement ps = objConn.prepareStatement(updatePurchase);
         ps.setString(1, ws);
         ps.setString(2, wm);
         ps.setString(3, wl);
         ps.setString(4, wx);
         ps.setString(5, wxx);
         ps.setString(6, bs);
         ps.setString(7, bm);
         ps.setString(8, bl);
         ps.setString(9, bx);
         ps.setString(10, bxx);
         ps.setString(11, tq);
         ps.setString(12, tp);
         ps.setTimestamp(13,ts);
         ps.executeUpdate();
         ps.close();
         objConn.close();
            catch (SQLException s)
                System.err.println("DataBase PROBLEM");
                s.printStackTrace();
            catch (Exception e)
                    System.err.println("Error in updateStore method");
                    e.printStackTrace();
} The prepared stmts seem to be "hanging on to" the access(dont laugh)table that the prepared stmt just updated. The reason I know this is because when I try to look at the table in access's design view I get a message saying:
"Microsoft access
You cant open the table 'store' for modification.
A query or form bound to the table is open, you may not have permission to open this table in design view, or another user has the table open.
If you have opened a query or form bound to this table, close it, and then try again to open the table in design view."
The only way to open the table in design view is to shut down tomcat and restart.
Should I be worried about this?
Am i forgetting to close something in my ps?
TIA!!

I use PreparedStatement all the time with Access and never have a problem. The only thing I noticed about your code is that if an exception gets thrown in your method, the close statements won't get executed. This might leave the tables locked. You might want to try moving the close statements into a finally block. That way your statement and connection will get closed if an exception gets thrown or not.
