Eclipse Remote Debugging Not Working

[Sanjay sagar]

Hi

I am stuck up with Elipse Remote debugging on unix server. My project is a core java project.

I am following the steps below :
(1) Using ANT I am creating the JAR file on windows
(2) Copying the JAR file on sun solaris
(3) I am using following command line options.
java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,add
ress=9000,suspend=n -Djava.library.path=${InstallPath} ...
(4) From Elipse using "Remote Java Application" giving "Host" and "Port" 9000

I am getting error :
"Failed to connect to remote VM. Connection Refused."

Alternatively I tried to install Eclipse on Solaris but I don't understand (1) why Eclipse has ZIP file for installation on solaris, why not TAR file ?
(2) what's the difference between GTK and MOTIF ?
(3) I tried installing GTK as well as MOTIF, but getting crazy errors like
!SESSION Fri May 12 19:45:28 IST 2006 ------------------------------------------

Any help is greatly appreciated.

"Connection refused" means that you didn't start the remote application. It can alternatively mean that a firewall is blocking you, but since you didn't mention starting the remote app yourself, I suspect that it isn't running.

As far as no TAR distro of eclipse, my guess is 3 reasons: 1, the Eclipse authors are more comfortable with ZIP, 2, Unix understands zip, but not all Windows systems understand tar and they didn't want to make things more complicated by having 2 file formats, 3, TAR isn't as portable as ZIP - the Solaris version especially isn't completely compatible with gnu tar.

I tried the MOTIF version of Eclipse. It looked ugly and clunky. These days I stick to the GTK version. MOTIF is an old traditional GUI API for X Windows, but it's not as polished as newer ones like GTK.
