Understanding J2 architecture

Hi,

I'm writing  a document about Jetspeed architecture and I would like to 
know your opinion about some pictures I want to include.

The first one tries to show the component architecture of J2, and how it 
depends on Spring to build the components
http://i11.photobucket.com/albums/a183/koishi/Diapositiva8.jpg

The second one is intended to show the main components involved in 
generating the portal page for the client request.
http://i11.photobucket.com/albums/a183/koishi/Diapositiva9.jpg
Dotted lines are responses, while solid lines are requests.
Pipeline component relies on some other components to create the valves, 
right? Like security in order to create the security valve...

Thanks in advance,
Enrique

There is also Eclipse JST and MyEclipse if you need a wider range of 
application servers.

Re: Debugging with Eclipse

Hi Evi.

Even if you found another solution...

The missing j2-admin::* portlets indicate that the j2-admin portal
application has not been deployed in your app server.

I like sysdeo because:

- it's simple
- enables you to keep the existing tomcat configuration
- quick start/stop/restart from within eclipse
- decreases the time needed for development cycles (edit, recompile,
deploy) (this is sometimes painful with java webapps)

In my enviroment I basically use the plugin to start/stop tomcat and to
run the tomcat inside eclipse for debugging (no context injection). I
have my fixed context files inside the tomcat conf directories that
point to the project directories. This makes it possible to change a
java src file and have it recompiled by eclipse (auto compile) and under
most circumstances tomcat picks um the changes immediately (without
restarting).

Maybe I am a bit old fashioned, because I already used the sysdeo
solution with jetspeed1. There might be a better solutions.

Regards,
Joachim

RE: Debugging with Eclipse

Posted by evi <ev...@evi.pri.ee>.
Thanks, Enrique, your advise was most helpful:-)

I also found some additional advise on
http://forum.java.sun.com/thread.jspa?threadID=752624 for being able to
start/stop Tomcat inside Eclipse as well by configuring startup.bat file:

4)Open startup.bat(inside the bin folder of tomcat) and search for call
"%EXECUTABLE%" start %CMD_LINE_ARGS%. Its at the end of the file. Replace
this with call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS% (mind the spaces,
better copy and paste).

So piece by piece it starts to clear up!

Evi, you don't need any tool, you can use the JPDA API.

Simply set the following shell variables (or something similar in windows):

    JPDA_TRANSPORT=dt_socket
    JPDA_ADDRESS=8000
    export JPDA_TRANSPORT JPDA_ADDRESS


And start your tomcat as follows:

    $TOMCAT_HOME/bin/catalina.sh jpda start


Now you can debug the JVM connecting to the port 8000.

In Eclipse you must do:

1. Run > Debug ...
2. Select "Remote Java Application"
3. Press new button
4. Configure your settings
5. Press Debug button

RE: Debugging with Eclipse

Thanks Joachim,

I installed the latest Sysdeo plugin and even found a nice tutorial
(http://www.keyboardsamurais.de/2004/01/15/tomcat_tutorial_helloworld_for_co
mplete_fools_-_english/). 

But when I started Tomcat within Eclipse and open my J2 portal, the admin
portlets Login and Locale Selector (and some other portlets as well) are not
available (Portlet is Not Available: j2-admin::LoginPortlet Reason: null).

At the same time my own little Hello World portlet is OK. 

Any ideas what might be wrong and why the portal acts differently when
Tomcat is started in Eclipse? A am using Tomcat 5.20,
sysdeo.eclipse.tomcat_3.2.0.beta3, Jetspeed-2.1.

Regards,
Evi

There are two modes of operation in Jetspeed: "Portal" mode and  
"Desktop" mode
You can checkout either one by navigating to (assuming running Tomcat  
on localhost 8080):

# Portal mode
http://localhost:8080/jetspeed/portal

# Desktop mode
http://localhost:8080/jetspeed/desktop

When we wrote our Desktop page decorators, we gave examples in both  
Velocity and JSP
The actual template used is configured in the  
decoratordesktop.properties of each decorator:

desktop.template.extension=.jsp

(Unfortunately the documentation for 2.1 did not get completed, so  
most of the desktop is undocumented)

For Portal mode, we have only implemented page decorations with Velocity
There is nothing keeping you from writing a JSP-based decoration  
template, it should work

Yes, recommend creating your own page decoration to get rid the  
action bars
It would be nice to have this parameterized as a feature though, so  
that you don't have to go through all that trouble
Go ahead and create a JIRA issue if you think its worthwhile

There are several, see:

You can specify what modes are available for a portlet in the portlet
descriptor (inside "supports" tag). That way, the portal knows which
controls should be added to the portlet window. If the only mode
supported is the VIEW mode, portal should not provide edit or help icons.
But I think that window status decorations are always available this
way... though I could be wrong.

If you don't want any control to be displayed, I think you can use
"pretty-single-portlet" decorator which, as far as I can remember, does
the same thing you've just done.

Hi Evi,

You may also want to check out the Jetty launcher for Eclipse.  I have found it to be much easier to configure and get working than the Sysdeo Tomcat plugin and Jetty starts up quite a bit faster than Tomcat does.

Debugging with Eclipse

Hi!

In Jetspeed-2 site there is a page about developing Jetspeed with Eclipse.
Unfortunately the part of Debugging with Eclipse is not finsihed yet. 

Is information about Debugging with Eclipse available elsewhere?
