i'm a new user of Eclipse.
I find Eclipse a very powerfull tool, but i'm trying to configure it for

debug this kind of application ?
can you help me ? :)

You need special tools to debug jsp inside Eclipse. I've not used
any of them, as I always use the latest version (or sometimes, the
nightly builds), and the tools just can't keep up with that.
But debugging servlet is just working fine without any tool, all
you have to do is to set up Eclipse to connect "remotely" to Tomcat.
You need to start tomcat with the jpda option
./catalina.sh jpda run
Then click on the little bug icon to bring the debug config dialog.
Create a new configuration of "Remote Java Application", and put
the hostname of the machine where tomcat is running on, and the port
number (default is 8000).
Then you can just start debugging servlet just like any java code.
I believe you can actually debug jsp inside Eclipse without any
special tool too, but so far, I still haven't figured out how :)

It is not all that difficult to debug JSP inside Eclipse without using a
plugin. This is what I did. My project is called jsp_test.
I created a directory called work under my project root in Eclipse.
(D:\eclipse\workspace\jsp_test\work). Added this as a source directory
(right click on project - Properties - Java Build Path - Source - Add
Folder). Then I created 'org/apache' directory structure in 'work'.
Next I modified server.xml and added a Context tag
<Context path="/jsp_test" docBase="jsp_test" debug="0"
reloadable="true" crossContext="true"
workDir="D:/eclipse/workspace/jsp_test/work/org/apache">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="localhost_examples_log." suffix=".txt"
timestamp="true"/>
Please note the value of workDir attribute. Basically I told Tomcat
where to place generated Servlet.
I put my JSP files in TOMCAT_HOME/webapps/jsp_test/jsp. I start Tomcat
from within Eclipse by creating a new runtime configuration with the
following attributes
Main class : org.apache.catalina.startup.Bootstrap
Program arguments : start
VM arguments: -Dcatalina.home=D:/jakarta-tomcat-4.1.27
Classpath : all jars in TOMCAT_HOME/bin,TOMCAT_HOME/server/lib.
The first time you access the JSP the Servlet is created. Refresh the
project files (right on project - Refresh) to load the generated Servlet
code into Eclipse. Now you can place a breakpoint anywhere in the code.
The downside to this method is that you can't debug your JSP the first
time you access it as there is no Servlet source code available.
Please let me know if there is a better way of debugging JSPs (without a
plugin) in Eclipse.

vinod.

I'm trying to use Eclipse 3.0M3 and the 2.1.1 Sysdeo plugin to
debug several JSP web apps which share a common bunch of
application and session beans.
I can work on a single app just fine, with the bean sources in
WEB-INF/src etc, but I'm having trouble pulling them out into a
separate project; how should I refer to them so that Tomcat is
able to start them on demand? I can get everything to build
OK but Tomcat wants to instantiate them dynamically and can't
find them...
(also I'd like to be able to export WAR files which contain the
bean .class files in WEB-INF/classes, or JARred in WEB-INF/lib)
