>Description:
Hi, the following snippet of code works fine standalone, but crashes
JServ when used in JSPīs or in Servlets. Iīve verified the error using
GSP, GNU jsp (both 1.0cvs and 0.9.10) and a servlet.
The snippet of code works fine with sunīs reference implementation
jwsdk, and when running it standalone, so itīs probably not a problem
with Weblogicīs 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());
}
}
}

Running that page results in the following messages being written to

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