Dear Experts,

I am a newbie to MyEclipse, JBoss. I got a problem in doing remote debugging with JBoss. Please kindly help.

1) I downloaded and installed MyEclipse 3.8.4 and JBoss 3.2;
2) I properly configured MyEclipse such that I can start up JBoss directly through MyEclipse;
3) After starting up the server, I successfully deployed my web project to JBoss through MyEclipse;
4) I clicked RUN–>DEBUG… and did the following settings at MyEclipse Externally Launched Server:
– Name: JBoss
– Project: myWebProject <– this is my project
– Connection Type: Standard (Socket attached)
– Connection Properties:
Host: localhost
Port: 8080
5) When I started debug, an error message was prompted:
“Exception occured during launch. Reason: Failed to connect to remote VM.”;
6) I checked that JBoss was started up properly by visiting http://localhost:8080 – the welcome page of JBoss server. I really don’t know what’s going wrong.

Could you please help me solving this problem? What should I do to locate and fix this error? Please help.

Many thanks.
Vincent

You are making this much harder than it needs to be… once you started JBoss from MyEclipse (assuming you left the Launch settings alone) all you need to do is start setting break points in your files and that’s it, it is already connected and ready to debug.

PLEASE NOTE: That JBoss 3.2 (IIRC) ships with Tomcat 4.x, that does not support the JSR 45 spec which is needed for full (JSP) debugging. If you want full debugging be sure to be running atleast Tomcat 5 as the servlet container for JBoss.

Thank you so much Riyad. I got it. Have a good day.

Dear experts!

on a gentoo linux box (1)

i am running a J2EE AS 
jboss Version: 3.2.5  
VM: Java(TM) 2 Runtime Environment, Standard Edition (build Blackdown-1.4.2-01) Java HotSpot(TM) Client VM (build Blackdown-1.4.2-01, mixed mode)

on a windows machine(2) iam runnung

 eclipse : Version: 3.0.2 Build id: 200503110845  
JBossIDE 1.4.1.e30
VM : java version "1.5.0_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_03-b07)
Java HotSpot(TM) Client VM (build 1.5.0_03-b07, mixed mode, sharing)

iam trying to do some remote debugging from the XP (2) machin to the gentoo box(1) and each time i try i get this error message:

Failed to connect to remote VM. Connection refused.
java.net.ConnectException: Connection refused: connect

org.eclipse.debug.internal.ui.DebugUIPlugin$6.run(DebugUIPlugin.java:955)
org.eclipse.core.internal.jobs.Worker.run(Worker.java:66)

on the remote machine i started jboss with

 JAVA_OPTS="-Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=4142,suspend=n"

and on the client machin where eclipse is running i created a “debug launch configuration” where i sprecified the IP number in hostname field and the same port number used in the JAVA_OPTS 4142

i expected at least when i did this thta i could see that the port 4142 is Listning but when runing netstat -l this port is not listning at all

please excuse my english skills and thanks for any kind of help

Yassine,

First, it appears that you’re using both JBoss IDE and MyEclipse, so you’ll likely have a confusing overlap of functionalty.
That said, you can find how to configure MyEclipse for proper remote debugging by reading our Remote Debugging quickstart.
It’s available in the Help section of the product in Help > Help Contents > MyEclipse Application Developer Guide or on
the website in the Documentation section here:
http://myeclipseide.com/enterpriseworkbench/help/index.jsp?topic=/com.genuitec.myeclipse.doc/html/quickstarts/remotedebugging/index.html

[Yassine ELassad]

Dear Scott,
first thanks for your add ! i tried to read the documentation you points me to and i am afraid i could not finde something that explains what you told me

it appears that you’re using both JBoss IDE and MyEclipse

i found in the documentation more informations and options to start the JVM in the debugging mode and this is what i tried:
1 i seted the JAVA_OPTS of my envirement to

export  JAVA_OPTS="-Xdebug-Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"
and then :
root@remote yel # export | grep JAVA_OPTS
declare -x JAVA_OPTS="-Xdebug-Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"

root@remote yel # /usr/share/jboss/bin/run.sh
=========================================================================

  JBoss Bootstrap Environment

  JBOSS_HOME: /usr/share/jboss

  JAVA: /opt/blackdown-jdk-1.4.2.01/bin/java

  JAVA_OPTS: -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n -Dprogram.name=run.sh

  CLASSPATH: /usr/share/jboss/bin/run.jar:/opt/blackdown-jdk-1.4.2.01/lib/tools.jar

=========================================================================

right now i checked the server if its listning to the port 8000:

root@remote yel # netstat --numeric -l
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State

[b]Note the port 8000 is not listed above[/b]

and then i tried to start debugging from eclipse after setting this :

and gets the same error msg

Yassine,
First check to make sure your firewall is allowing incomming connections on the machine hosting “developers.de”, I doubt it is. Additionally you are using JBossIDE to debug, you really should check with the JBoss support forums on what is going wrong, we don’t work on that project.

[Yassine ELassad]

Dear Riyad,

well i have only some iptables rules which are not bloacking any incomming connections and i dont think that its a matter of firewall since the AS not listning to the specified port nr 8000 so your right im going to try in the jboss forum and see what they will advise me to do and i will post what i get there here too 🙂
thanks all!

[dhariyan]

Riyad,

Can you please clarify the difference between the MyEclipse IDE and the JBossIDE? I thought MyEclipse is the IDE and JBoss is simply the application server that contains EJBs and things of that sort. So, shouldn’t the MyEclipse IDE be able to attach to a process that is running in JBoss and debug the code from there? thanks.

[Riyad Kalla]

dhariyan,
Yes you are correct, however the JBoss team does have an Eclipse based product called “JBossIDE”, and the screenshots and information Yassine was posting was all in regards to *that* plugin, they weren’t for MyEclipse’s functionality.

[chenff]

Is it possible to use JbossIDE along side with MyEclipse then is my question? I am using Hibernate 3 so would like some help from JBossIDE before MyEclipse can provide that function in 4.1 (maybe). Thanks.

[Riyad Kalla]

Hibernate 3 functionality will be in our 4.0 release.

However, as far as if JBossIDE and MyEclipse work with eachother, there may be some overlap, but if you are aware of which plugin does what, I think they should work fine… don’t take my word on it though, that is not a tested configuration.
