I am getting the following exception javax.naming.NoInitialContextException: Cannot
instantiate class: weblogic.jndi.WLInitialContextFactory [Root exception is java.lang.ClassNotFoundException:
weblogic/jndi/WLInitialContextFactory]

Peoplesoft application is customized to run a java program and this program is
trying to do Initial context and I am getting the above exception. Peoplesoft
application server has Weblogic 6.1 SP4 and /classes directory has weblogic.jar
file. Strangest thing is that when I load this class using Class.forName it works
fine but it is giving exception with InitialContext(properties).

try
{
c = Class.forName("weblogic.jndi.WLInitialContextFactory");
}
catch (ClassNotFoundException e)
{
System.out.println("ClassNotFoundException:" + e.toString());
}
catch (Exception e)
{
System.out.println("Exception:" + e.toString());
}
System.out.println("----Class name:" + c.getName() );

Above code works fine. I get the class name correctly which is given below.
----Class name:weblogic.jndi.WLInitialContextFactory

Following code is throwing an exception which is listed at the top.
properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
properties.put(Context.PROVIDER_URL, url +":" + port);
properties.put(Context.SECURITY_PRINCIPAL, user);
properties.put(Context.SECURITY_CREDENTIALS, password == null ? "" : password);

try
{
this.initialContext = new InitialContext(properties);
}
catch (NoInitialContextException e)
{
System.out.println("NoInitialContextException:" + e.toString());
}

catch (NamingException e)
{
System.out.println("NamingException:" + e.toString());
}
catch (Exception e)
{
System.out.println("Exception:" + e.toString());
}

Any ideas on this is appreciated.

Is weblogic.jar in the classpath?
weblogic.jndi.WLInitialContextFactory is in weblogic.jar

Yes, weblogic.jar is in classpath. weblogic.jar has weblogic.jndi.WLInitialContextFactory.class

My money is still on something being wrong in your classpath.

Can you print out the $CLASSPATH your server is using and then do

javap -classpath $YOURCLASSPATH weblogic.jndi.WLInitialContextFactory

classpath being used by the appserver: /ps/psdev/appserv/classes:/ps/psdev/appserv/classes/weblogic.jar:/ps/psdev/appserv/classes/com:/ps/psdev/appserv/classes/weblogic

I did javap and this is what I got.
[***@psdevapp]$ javap -classpath /ps/psdev/appserv/classes:/ps/psdev/appserv/classes/weblogic.jar:/ps/psdev/appserv/classes/com:/ps/psdev/appserv/classes/weblogic
weblogic.jndi.WLInitialContextFactory
Compiled from WLInitialContextFactory.java
public class weblogic.jndi.WLInitialContextFactory extends java.lang.Object implements
javax.naming.spi.InitialContextFactory {
public weblogic.jndi.WLInitialContextFactory();
public final javax.naming.Context getInitialContext(java.util.Hashtable) throws
javax.naming.NamingException;
}

It looks good to me.

Very odd. Can you try
Class.forName("weblogic.jndi.WLInitialContextFactory", true,
getClass().getClassLoader());

and show me the output?

I did what you asked me to do and It loads the class correctly. How do I get the
output you are looking for.

Thanks
