Thanks. I will look at that. This is my connection:
package um.persistence; import java.sql.Connection; import java.sql.SQLException; import javax.servlet.http.HttpServlet; import java.sql.DriverManager; public class PersistenceFacade { //----------- fields ---------// public static final String CONNECTION_DRIVER = "com.microsoft.sqlserver.jdbc.SQLServerDriver"; public static final String CONNECTION_USER = "username"; public static final String CONNECTION_PASS = "password"; public static final String CONNECTION_URL = "url"; static { try { Class.forName(CONNECTION_DRIVER); } catch (ClassNotFoundException ex) { ex.printStackTrace(); } } private String connectionUrl = null; private String connectionUser = null; private String connectionPass = null; //------------ constructors -----------// //public PersistenceFacade() {} public PersistenceFacade(HttpServlet servlet) { connectionUser = servlet.getInitParameter(CONNECTION_USER); connectionPass = servlet.getInitParameter(CONNECTION_PASS); connectionUrl = servlet.getInitParameter(CONNECTION_URL); } //------------- public methods -----------// public Connection getConnection() throws SQLException { System.err.println("getConnection startet!"); if(connectionUser == null) { throw new SQLException("Missing parameter "+CONNECTION_USER); } else if(connectionPass == null) { throw new SQLException("Missing parameter "+CONNECTION_PASS); } else if(connectionUrl == null) { throw new SQLException("Missing parameter "+CONNECTION_URL); } return DriverManager.getConnection( connectionUrl, connectionUser, connectionPass ); } public void closeConnection(Connection conn) { try { if(!conn.isClosed()) { conn.close(); } } catch (SQLException ex) { ex.printStackTrace(); } } //------------ private methods ----------// } And I call the PersistenceFacade like this: PersistenceFacade persistenceFacade = new PersistenceFacade(getServlet()); conn = persistenceFacade.getConnection(); I get no errors only a white screen!!!!! ----- Original Message ----- From: "Christopher Schultz" <[EMAIL PROTECTED]> To: "Tomcat Users List" <users@tomcat.apache.org> Sent: Friday, June 22, 2007 2:26 PM Subject: Re: Realm works; db connection does not? > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Søren, > > Søren Blidorf wrote: > > I do mean realm and the reason why I mention it is that I can validate users > > via my users and user_roles in my db, so the connection should work I guess? > > That depends upon your connection settings. > > > <Context path="/xx" docBase="webapp" reloadable="true"> > > <Realm name="UMRealm" > > This looks good... and it should, since it apparently works. > > > Get the connection with: DriverManager.getConnection( connectionUrl, > > connectionUser, connectionPass) > > This is just about the simplest way to get a connection.
