IPLANET AND WEBLOGIC

Question

Hi,
I Am using the t3 protocol to connect to the server in the BEA weblogic, now
I am porting my beans to IPLANET, now how can I make use of the Attached
piece of java code, the file makes use of the table called "ts_lookup".
java file
package com.se.util;
import javax.naming.*;
import java.util.*;
import javax.sql.*;
import java.sql.*;
import javax.ejb.EJBException;
@author Author
public class Lookup extends Object
@roseuid 39EAE91F015B
public static java.lang.Object getHomeObject(String lookUpID) throws
java.rmi.RemoteException, EJBException
Connection con = null;
PreparedStatement ps = null;
String initialContextFactory = null;
String providerURL = null;
String securityPrincipal = null;
String securityCredentials = null;
String jndiName = null;
try {
con = getConnection();
ps = con.prepareStatement("SELECT * FROM tu_lookup WHERE lookUpID = ?");
ps.setString(1, lookUpID);
ResultSet rs = ps.executeQuery();
file://ResultSet rs = ps.getResultSet();
if (rs.next()) {
initialContextFactory = rs.getString("initialContextFactory");
providerURL = rs.getString("providerURL");
securityPrincipal = rs.getString("securityPrincipal");
securityCredentials = rs.getString("securityCredentials");
jndiName = rs.getString("jndiName");
} else {
String error = lookUpID + " not found in table tu_lookup";
System.out.println(error);
throw new EJBException (error);
} catch (SQLException sqe) {
System.out.println("SQLException: " + sqe);
throw new EJBException(sqe);
finally {
cleanup(con, ps);
Object homeObj =null;
try {
// Get an InitialContext
Properties h = new Properties();
h.put(Context.INITIAL_CONTEXT_FACTORY, initialContextFactory);
h.put(Context.PROVIDER_URL, providerURL);
if (securityPrincipal != null) {
h.put(Context.SECURITY_PRINCIPAL, securityPrincipal);
if (securityCredentials == null)
securityCredentials = "";
h.put(Context.SECURITY_CREDENTIALS, securityCredentials);
Context ctx = new InitialContext(h);
homeObj = ctx.lookup(jndiName);
} catch (NamingException ne) {
file://call the exception handler
System.out.println("NamingException: " + ne);
throw new EJBException(ne);
return homeObj;
* Gets current connection to the connection pool.

public static Connection getConnection()

String poolName = null;

DataSource ds = (javax.sql.DataSource) initCtx.lookup(poolName);
return ds.getConnection();
} catch(MissingResourceException mre) {
System.out.println("UNABLE to find the Lookup.properties file");
throw new EJBException(mre);
} catch(NamingException ne) {
System.out.println("UNABLE to get a connection from "+poolName+"!");
System.out.println("Please make sure that you have setup the connection
pool properly");
throw new EJBException(ne);
} finally {
try {
if(initCtx != null) initCtx.close();
} catch(NamingException ne) {
System.out.println("Error closing context: " + ne);
throw new EJBException(ne);

throw new EJBException(ne);
public static void cleanup(Connection con, PreparedStatement ps) {
// Having problems with ps.close.
/*try {
if (ps != null) ps.close();
} catch (Exception e) {
System.out.println("Error closing PreparedStatement: "+e);
throw new EJBException (e);
try {
if (con != null) con.close();
} catch (Exception e) {
System.out.println("Error closing Connection: " + e);
throw new EJBException (e);
The structure of the ts_lookup is like this
CREATE TABLE tu_lookup (
lookUpID char(30) NOT NULL ,
initialContextFactory varchar (100) NOT NULL ,
providerURL varchar (100) NOT NULL ,
securityPrincipal varchar (15) NULL ,
securityCredentials varchar (15) NULL ,
jndiName varchar (25) NOT NULL
sample data row for the above table is like this
ItemHome weblogic.jndi.WLInitialContextFactory
t3://208.28.177.22:7001 ItemHome
UnitMasterHome weblogic.jndi.WLInitialContextFactory
t3://208.28.177.22:7001 UnitMasterHome
ShowColumnsHome weblogic.jndi.WLInitialContextFactory
t3://208.28.177.22:7001 ShowColumnsHome
CustomerHome weblogic.jndi.WLInitialContextFactory
t3://208.28.177.22:7001 CustomerHome

I don't know exactly what you want to achieve, but can't you just check it in the log or check the open connections with 'netstat' which shows you which connections are open
