This is not one I've seen. If this Tomcat is not from a downloaded zip
or tar.gz, or if its configuration has been customized, you can try
creating a fresh Tomcat from a zip or tag.gz. Then see if Eclipse has
the same issue with that one. When the Tomcat plug-ins create a new
Tomcat server, the current server.xml will be imported from the Tomcat
installation. There can be customizations present that cause problems
within Eclipse because they require additional configuration beyond what
the plug-ins know how to import. This experiment would eliminate that
as the cause.
Cheers,
Larry

Update, as I am still at a lost on this problem
I have checked many more things, but still no luck, and I ran into another problem which seem to tell a little more about was may be the core issue.
I cannot run JUnit (junit4) tests. I will run fine, but no success/failed. I tried then running JUnit with debugging and Eclipse gave the following message:
----
Cannot connect to VM
Unrecognized Windows Sockets error: 0: JVM_Bind
----
Searching on this, I found that it possible that Eclipse is launching a different JVM that it cannot connect to. So I went to work on my PATH, and made sure that there was only the same JAVA available as I am using inside Eclipse. But no luck however.

Unfortunately, since I'm not able to duplicate this it is hard to offer
much help. If you are still having a problem, does starting Tomcat in
debug mode result in the same kind of behavior as JUnit, or can it start
with just 8005 in use?
Cheers,
Larry

Hi again Larry, thanks for the effort, good idea, I had not thought of that.
So as you suggested I tried debug the server with just the 8005, and then it fails immediately with the following message.

Not that it says a whole lot, but it seems to me it is perhaps less of a Tomcat issue, and more an Eclipse issue. Well for now I will just have to run Tomcat using the batch script. That Junit does not work do bug me a bit though.
Also with regards to JUnit, I tried getting another Eclipse Helios, that only have basic Java (eclipse-java-helios-win32.zip), and problem is exactly the same.
Also (even further out, but never know what information is useful), I installed Oracle Weblogic 11g last week, and I can run the portal domain there from within "Eclipse for Weblogic" without any problems at all.

Dear Tommy
The problem just recurred and I advanced a bit in its understanding.
I am running Tomcat outside of Eclipse on ports 8080, 8009 and 8005 and inside on ports 9090, 9009 and 9005. When Eclipse reported that the ports were taken, I looked up the file "server.xml" of the external Tomcat (C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf) and found that the ports were changed to 9090, 9009 and 9005. I have not touched that file. How they could have been changed I do not understand. I changed them back to 8080, 8009 and 8005, restarted Tomcat in the Windows Services panel and was fine.
I wonder whether the same is happening on your machine. Besides, mine is a laptop running under Windows XP.
Best regards, Johannes

If you selected, even temporarily, the "Use Tomcat Installation (takes
control of Tomcat installation)" option for the Server Location in the
server editor, it would overwrite the server.xml in your installation
with the one under the Servers project in your workspace. This is the
meaning of "takes control of Tomcat installation". That's the only way
I know of that would "transfer" those port settings.
Cheers,
Larry

For what it's worth, I install separate, private copies of the Sun JDK
and Apache Tomcat for dedicated use with Eclipse. That way, no matter
what else I might have occasion to do on my development host, nothing is
there to interfere or confuse me when writing code (apart from my own,
recurring moments of stupidity).

It's probably a better idea NOT to hijack this thread, Aswini. Start a
new one.
In the meantime, you don't give enough to go on. You're probably missing
one or more Tomcat libraries.
Do you have questions on how to set up Tomcat and Eclipse?

To get to the server editor, double-click the server in the Servers
view, or right-click it and select Open. The "Switch Location" is for
choosing where to store the metadata about the server configuration.
For additional details see the Tomcat_FAQ[1].

Larry
