I have jboss application server running on my machine which deploys an .ear
file. My clien is another java application that talks to this server.
As a developer I needed to figure out how to be able to debug the deployed .ear
from within eclipse so that I could see the values of member and local
variables of ejbs, just as I am able to see the values of member and local
variables of the client. I figured this out by implementing the following
directions

of the IDE. This is very simple to do and requires only one small alteration to
the jboss startup script.

| Edit the run.bat/run.sh file and uncomment the line "rem set
JAVA_OPTS=-classic -Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y %JAVA_OPTS%".
| Start Eclipse (I'm using ver 3.1 with JBoss IDE 1.5 M2) and open your
workspace.
| Click on the Run--->Debug... menu.
| Select "Remote Java Application" in the left pane and then click new.
| Name the configuration, fill in the IP address and the port number (this
must be the same as the one defined on the server, e.g. 8787 by default).
| Click apply but keep the window open.
| Start the JBoss Server (or restart it if it's already running). The server
will block waiting for the connection from the remote client.
| Go back to the dialog box in eclipse and click Debug.
| and that's it!
So basically I am having a remote connection to the server running on my
machine and thus the server and client are using the same jvm. During debugging
I noticed that I could easily see the values of variables that were the member
varialbes of an ejb, but if any local variable was created like in a method (
on the stack ), I could not decipher its value or it was not resolvable. eg.
Vector queryvalues = new Vector();
if (userid != null)
{
if (!userid.equals(""))
{
queryvalues.addElement(new QueryValue("getSuserid", userid, "=="));
}
}In the above code I could see what userid contains since that is the
member variable of the class from which the code was taken but I would not be
able to inspect queryvalues since it was created locally.
could anyone tell me how I would be able to inspect local variables when remote
debugging a jboss server deployed ear.
thank you
