I have tried to check the log but just did not find it!
Any advise is highly appreciated.

Here is the latest clarification.
OS: Red Hat Linux 9
Eclipse: 2.1.1 SDK GTK
Browser: Mozilla (indicated as a custom browser at window -> preferences
-> help as 'mozilla %1', the browser is in path and can be launched from
the command line.
Problem: Upon requesting Help Contents browser starts but there is an
empty page index.jsp shown in the browser window. Requesting a page
'http://127.0.0.1:<random generated by Eclipse port number>/' shows page
'Internal Application Server' which is redirected to the empty page
'http://127.0.0.1:<random generated by Eclipse port number>/help/index.jsp'

/home/alex/workspace/.metadata/.plugins/org.eclipse.help/bro wser.log is as
follows:

Eclipse is located at /usr/local/share/eclipse directory and launched
under user 'alex'. workspace is located at /home/alex/workspace.
/ROOT and /help directories of
/home/alex/workspace/.metadata/.plugins/org.eclipse.tomcat/ are empty.
It looks that content is not being copied (or generated ?) to the
/home/alex/workspace/.metadata/.plugins/org.eclipse.tomcat/h elp

Any suggestions on how to fix that?

Do you have any sort of firewall/proxy on your machine that may not allow
using some arbitrary port?
If that's the caes, try setting the port in the Window > Help preference
page to 80 or something else that is allowed by the firewall.

The cause of the problem should have been logged in eclipse log
"/home/alex/workspace/.metadata/.log" . It is a hidden file. Are you sure
it does not exist?

is redirected to /help/index.jsp which is an empty page.

If I try to indicate not random port but a fixed port 80, an error log is

there is no content generated. When /help/index.jsp is accessed an empty
page is shown.

Is there a solution to Alex Karpovs problem?
Same problem since version 2.1 of eclipse on my Windows98SE.
Tomcat is running, all html-content is available, all JSP-requests deliver
empty HTML-files.
No entries in .log-file

If you are using a proxy you may need to bypass local addresses. Take a look
at the README, there is a section on Help.

Much thanks for the prompt advice!

It isn't a proxy problem.
On this machine a standalone Tomcat is running without any complaints.

To find the reason for the malfunction I've tried to transfer the
index.jsp under org.eclipse.help and the WebApp under
org.eclipse.help.webapp into the standalone Tomcat and got the
errormessage:

package org.eclipse.help.internal.webapp.data does not exist ...

This is caused by a directive in the index.jsp-file:

<%@ page import="org.eclipse.help.internal.webapp.data.*" ...

I didn't found a package org.eclipse.help.internal.webapp.data in whole
eclipse-code.

be
http://<server:port>/help/topic/org.eclipse.help/plugin.xml
Do you get the xml loaded or it is still a blank page?

Check the logs in

You will get error messages because the webapp cannot just be depolyed
inside Tomcat, it only works with
the embedded tomcat, as there is some class loading setup that must happen
first.

The code is in the CVS project org.eclipse.help.webapp, in the src-servlet
directory. The jar containing the classes is
org.eclipse.help.webapp_2.1.1/WEB-INF/lib/servlets.jar

Now a status-error 500 - Server internal error is served.

No items in .log-file are written.

No, I don't have.

In eclipse3.0M4 I get the same Tomcat-log.

I hope it's not too boring to guide me through perhaps special
configuration-oddities of my system.
Can you give some advice where to trace the evil? I would dare to find and
fight it.

Then, do you have a servlet.jar in your <jdk_install>\jre\lib\ext ?

Gotcha!
I threw that ugly old servlet.jar-frog onto the wall and look! the lovely
sight of helpcontents pleased my eyes.
Much thanks for patient guidance.

May I generalize the result of our search through logs and configs?

Since eclipse-version 2.1 the internal mechanism of calling the customized
Tomcat-server has changed. With customizing also has changed structure of
directories in which packages are placed, the same with preferences of
classloading.

Now a servlet.jar in <JAVA_HOME>\jre\lib\ext\ prevents help-window from
displaying any dynamically generated content. It smells like dll-hells but
it's not a version-problem. Any servlet.jar previous in calling-hierarchy
than
org.eclipse.tomcat_4.XXX causes this behaviour.

In his book "Java Servlet Programming" Jason Hunter states:
It doesn't much matter where you get the servlet classes, as long as you
have them on your system ...

An application on my system placed servlet.jar in <JAVA_HOME>\jre\lib\ext\
(Isn't that the right place for optional packages to Java?)

Isn't it buggy, that such a possible configuration of a target system e.
g. for standalone help suppresses correct function?

Hi Kurt,

Yes, I agree with your comments, particularly with the "dll hell" like
scenario.
You can also drop a different version of xerces in the ext directory and
you'll likely run into problems with eclipse 2.1.
I am not sure what the best solution is, but the reality is that this is one
of the unfortunate exceptions, and for most people things are working well.
If you can think of some fixes, please let us know, we'd be happy to use
your contributions.
