unable to use eclipse 3.4.1 on mac os x [message #258701]

Hello

I just installed eclipse version 3.4.1 on mac os x 10.5.6. I unzipped the
eclipse rcp file and placed it under the Applications directory. I wrote a
very simple helloWorld.java where I just have main that does a
System.out.println().

public class HelloWorld {

/**
* @param args
*/
public static void main(String[] args) {
System.out.println("hello world");
System.out.println("bye world");
}
}

When I run this application, nothing is shown in the output console. It
says launching and then terminated. But no output on screen. When I click
on debug, I get the following error in the log file (in .metadata in my
workspace)

!ENTRY org.eclipse.jdt.launching 4 120 2009-02-15 13:24:49.025
!MESSAGE Cannot connect to VM

I searched a lot on this newsgroup and on the internet. Some other people
seem to get this error but I did not find any answer.

Java installed on my computer:
java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b06-284)
Java HotSpot(TM) Client VM (build 1.5.0_16-133, mixed mode, sharing)

In the eclipse installed jre preferences window, I am using JVM 1.5.

I tried disabling the mac firewall in the settings section, but that did
not work either. Anybody got any ideas?

Thanks.

Take a look at https://bugs.eclipse.org/bugs/show_bug.cgi?id=124814

Thanks Dani, I looked at the bug report. I tried changing the /etc/hosts
file but it did not make any difference.
/etc/hosts file:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
localhost 127.0.0.1
127.0.0.1 127.0.0.1

Same error in the log:

!ENTRY org.eclipse.jdt.launching 4 120 2009-02-16 23:32:38.057
!MESSAGE Cannot connect to VM
!STACK 0

at java.lang.Thread.run(Thread.java:613)

I do not see any output in the console in eclipse. I think the person in
the bug sees output in the console when they run it. They don't see
anything when they debug. Just the error. When I just run the helloworld
program or the program listed in the bug report, I don't see anything in
the console. Just "started" and "terminated" in the view status. When I
use debug, I get an error windows saying "cannot connect to vm". Not sure
what is going on here. I can try reinstalling java on the mac, would that
help?

Thanks Daniel,
please ignore my other message. The problem is resolved now. It was my
mistake. my project was not a java project. i was trying to run a java
class in a non java project and the launch configuration was all messed
up. Pretty stupid on my part.

Eclipse rocks !!

Thanks again.
