Thread: class not found exception
Hello Postgresql users,
I wrote a normal java application(using main() method) and
successfully connected to postgresql database but when I connect to it
using JSP, Iam getting 'Class not found exception'.Iam using pg73jdbc1.jar and jdk1.4.1_04 and Red Hat Linux 9.0.The web server is
Jakarta Tomcat 5.0.4.Please help me.Send a reply as soon as possible.

Vijaya, Did you read this? http://doc.postgresintl.com/jdbc/ch11s04.html If you aren't using datasource's then can you post the code and your web configuration?

Hi All, We have hosted an web application and now it is live. s/w used : Apache, Tomcat 4.1.x, Postgresql 7.x It seems that there is a major problem with the database connectivity. What we are seeing is that over a period of time the database reports more and more connections from the our web application until the connection limit (100 on our setup) is reached. this is a sample code i am using across application. whether we need to release the connection explicitly ? As of now i have not released the connection only i have closed it .... ? /*****************************************************/ -------------my db class----------------- try { this.setConnection(ConnectionPool.getConnection()); ArrayList arrList = new ArrayList(); con.setAutoCommit(false); preStmt = con.prepareStatement("SELECT * from t"); resultSet = preStmt.executeQuery(); while (resultSet.next()) { ..... ..... } return arrList; } catch(Exception ex) { sberror.append(ex.getMessage()); return null; } finally { try { con.setAutoCommit(true); resultSet.close(); preStmt.close(); con.close(); } catch (SQLException e) { sberror.append(e.getMessage()); return null; } } -----------my Connectionpool class----------- public static Connection getConnection() { Connection con = null; javax.sql.DataSource ds; try { InitialContext ctx = new InitialContext(); ds = (DataSource) ctx.lookup("java:comp/env/jdbc/postgres"); if (ds != null) { con = ds.getConnection(); } else return null; } catch (Exception e) { return null; } return con; } /*****************************************************/ please help...
