Sql Exception :general error

Question

Dear friends,
Here I have mysterious problem connection and operating with Oracle thru bridge drivers.
That is , I have class JDBCManager which takes care of executing Sql statements like selection , insertion and updating. Another class named Server which contains JDBCManager as static member so that any class can all the member function. The Actual problem is that after executing certain number of queries I need to face "SQLException as General error". So please tell how to get rid of this error.
JDBCManager establishes new Statement for every query body of one method is defined as follows
public ResultSet niceQuery(String query)
ResultSet result;
try
//Enumeration keys=connections.keys();
System.out.println(query);
Statement stmt=connection.createStatement();
result=stmt.executeQuery(query);
//stmt.close();
return(result);
catch(SQLException se)
System.out.println("Sorry i can not");
System.out.println(se);
return(null);
null

You can try with 3rd type drivers. Which i have used in connecting my code to My SQL. as below:
jdbc:mysql://192.9.200.20:3306/dbname","username","password"
Try to find informix's third party drivers if available. Happy coding :)
