Hello,
I have all the required jar-files in the WEB-INF/lib directory (torque runtime
+ dbdriver).
My Torque.properties is in the WEB-INF directory.
I have the HelloServlet + the bank-classes in the WEB-INF/src directory.
Here the HelloServlet.java again:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import org.apache.commons.configuration.ConfigurationException;
import org.apache.commons.configuration.PropertiesConfiguration;
import org.apache.torque.Torque;
import org.apache.torque.TorqueException;
import persistence.Bank;
public class HelloServlet extends HttpServlet {
public void init() throws ServletException, UnavailableException
{
try
{
ServletContext ct = getServletContext();
PropertiesConfiguration config = new PropertiesConfiguration();
config.load(ct.getResourceAsStream("/WEB-INF/Torque.properties"));
Torque.init(config);
}
catch (ConfigurationException e)
{
System.out.println("Configuration: Initialisierung
fehlgeschlagen" + e);
}
catch (TorqueException e) {
System.out.println("Init: Initialisierung
fehlgeschlagen" + e);
}
}
public void doGet( HttpServletRequest requ, HttpServletResponse resp ) throws
ServletException,IOException
{
try
{
Bank sparkasse = new Bank();
sparkasse.setBankId(111); sparkasse.setName("Apache");
sparkasse.setCity("Torque");
// CREATE
sparkasse.save();
}
catch (Exception e)
{
System.out.println("initializing of Torque failed" + e); }
resp.setContentType( "text/html" );
PrintWriter out = resp.getWriter();
out.println( "" );
out.println( "Servus," );
out.println( "Torque!" );
out.println( "" );
out.close();
}
}
--> In the browser I get this message:
