I've modified the code to show the exception, it seems
endPoint.getRequestURI(),endPoint.getRemoteHost(), and
endPoint.getServerName() all return nulls.
I get a java.lang.NullPointerException.
Ideas?

When this part of the JSP runs
for (int i=0;i<count;i++) {
out.println("i: " + i + "<br>");
try
{
jrunx.scheduler.WorkerThread t =
(jrunx.scheduler.WorkerThread)threads[i];
jrun.servlet.http.WebEndpoint endPoint =
(jrun.servlet.http.WebEndpoint)t.getServletRequest();
out.println(endPoint.getServerName() + endPoint.getRequestURI() +
"<br>");
}
catch (Exception e) { }
}
I get
i:1
i:2
.
.
.
that's it. The try/catch is catching an exception. When I remove the
try/catch I get this in the cfusion-event log
java.lang.ClassCastException

looks like its this line that is having issue with the caste
jrunx.scheduler.WorkerThread t =
(jrunx.scheduler.WorkerThread)threads[i];

If you are using jrun for your J2EE server I don't know what the
problem could be.
What kind of error message are you getting?
Can you compile the code I posted?

hmmm, I am using the enterprise version, J2EE install, and I can not
see the script names.
This part bombs.
jrunx.scheduler.WorkerThread t =
(jrunx.scheduler.WorkerThread)threads[i];
jrun.servlet.http.WebEndpoint endPoint =
(jrun.servlet.http.WebEndpoint)t.getServletRequest();
maybe there is something missing in my classpath or maybe a differnet
JVM????

I like that. It worked great for me, but if you are not using
enterprise it will not work. For those people you can also do the
same thing with a servlet. Here is the java code.
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class threads extends HttpServlet{
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException{
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
Thread thread = Thread.currentThread();
ThreadGroup threadGroup = thread.getThreadGroup();
int count = threadGroup.activeCount();
Thread[] threads = new Thread[count];
count = threadGroup.enumerate(threads);
out.println("Thread Count: " + count + "<br>");
for (int i=0;i<count;i++) {
try
{
jrunx.scheduler.WorkerThread t =
(jrunx.scheduler.WorkerThread)threads[i];
jrun.servlet.http.WebEndpoint endPoint =
(jrun.servlet.http.WebEndpoint)t.getServletRequest();
out.println("i: " + i + ": <br>");
out.println(endPoint.getServerName() + endPoint.getRequestURI() + "
:" + endPoint.getRemoteHost() + "<br>");
}
catch (Exception e) {
}
}
}
}
compile and put in the WEB-INF/classes folder.
I compiled using javac thread.java -classpath
c:\cfusionmx\runtime\lib\jrun.jar
call it using
http://webserver.com/servlet/thread

there was some JSP code for this floating around abit ago. IIRC,
credit goes to Pete Frietag. I never got this to work for me though.
Some sort of caste error and I'm far from a Java guru. Anyone get
this to work?
<%
Thread thread = Thread.currentThread();
ThreadGroup threadGroup = thread.getThreadGroup();
int count = threadGroup.activeCount();
Thread[] threads = new Thread[count];
count = threadGroup.enumerate(threads);
out.println("Thread Count: " + count + "<br>");
for (int i=0;i<count;i++) {
out.println("i: " + i + "<br>");
try
{
jrunx.scheduler.WorkerThread t =
(jrunx.scheduler.WorkerThread)threads[i];
jrun.servlet.http.WebEndpoint endPoint =
(jrun.servlet.http.WebEndpoint)t.getServletRequest();
out.println(endPoint.getServerName() + endPoint.getRequestURI() +
"<br>");
}
catch (Exception e) { }
}

Well I've found the stack trace invaluable in terms of information.
But the fact that you have to have your server running through command
prompt makes its pretty useless.
For example in a production app, you have to shut down the server.
(not cool) Then restart it in a command window (not cool), then you
cannot log off! (not cool) Although I'm told this is a windows only
issue. Still, its great insight into problems... but you cant really
get it when you need it.

You can perform a dump of the current stack trace, which will list
(amongst a big pile of other stuff) what's requests are currently being
processed by CF. See the MM technote about it:
