>Description:
Hi, the following snippet of code works fine standalone, but crashes
JServ when used in JSP�s or in Servlets. I�ve verified the error using
GSP, GNU jsp (both 1.0cvs and 0.9.10) and a servlet.
The snippet of code works fine with sun�s reference implementation
jwsdk, and when running it standalone, so it�s probably not a problem
with Weblogic�s application server.
>How-To-Repeat:
this is the standalone program that works:
import javax.naming.*;
import javax.ejb.*;
import javax.jts.*;
import java.rmi.RemoteException;
import java.util.*;
import java.sql.*;
import java.math.*;
import java.text.*;
import java.util.*;
public class JServBug {
static String lacName = "reinhard";
static String lacPassword = "";
static String busId = "052";
static String weblogicUrl = "t3s://history.andsold.de:7004";
public static void main (String args[]) {
System.out.println("Hello world");
try {
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.TengahInitialContextFactory");
p.put(Context.PROVIDER_URL, weblogicUrl);
InitialContext ctx = new InitialContext(p);
} catch (Exception e) {
System.out.println (e.getMessage());
}
}
}
Here�s the GSP page that crashes JServ 1.0:

Running that page results in the following messages being written to

If you need more information I�d be happy to provide it.
>Fix:
No, not at the moment. As we need to use SSL we cannot use Sun�s
implemenatation, but it won�t work with Apache/JServ... looks like
a catch-22.
Keep up the good work, and again, if I can be of any help, I�ll try
my very best.
