Can't find valid port after upgrade to 3.1 [message #80582]

I've added a 3.1rc3 version to an existing 3.0.
Now the help system and the debugger can't find a valid port (for both
installations).
...
org.eclipse.core.runtime.CoreException: Application server could not
start, because it could not open a port.
at
org.eclipse.tomcat.internal.TomcatAppServer.start(TomcatAppS erver.java:176)
...
I did not change the environment (Win-XP sp2 Firewall and McAffee running).
Where do I have to take a look?

Thanks in advance
Wolfgang R.

Sorry, forgot to mention that I've upgraded the jdk from 1.4 to 5.0 as
well. Seems to be that some permissions outside Eclipse are lost.

Here is my experience.

On my PC Win-XP sp2 and its firewall was running. In addition
the McAfee firewall and virus scan. Installing jdk 1.5.0_04
raises the same problems under Eclipse 3.0. The local debugger
and the help system couldn't get a port.

I've rolled-back my system and the following way did work
for me

- don't have an Internet connection running
- disable all firewall stuff
- install the jdk
- start Eclipse and the local debugging
a msg box comes up that a program is looking for
Internet access
- I've granted access here and later on as well
- At last I've enabled the firewalls again
The jdk will not try to establish an Internet connection
this way. But it seems that some default setting within
the 1.5 jdk causes this new behaviour.

I was not able to get it running once the ports were not
allowed. But fortunatly for me my imaging software allows
me another try.

I'm still interested how to install the jdk correctly for
this purpose.

Wolfgang,

When debugging a java application, the debugger connects to the running
application using a network socket to localhost (or a remote
machine/port for remote debugging). This is how debugging works in Java,
so it's a matter of getting your firewall to allow connection requests
to your java application to be allowed from localhost.

Hope this helps,
- Jeff
