Hi David
I have been taking a look at your excellent "Constructing a
special-purpose server using maven" (link below) in the hope to
actually get Liferay 5.0.1 (rc1) running on Geronimo 2.1.1 in a
special purpose build. Working on this i noticed what I believe is
a typo in the documentation of the liferay-jetty pom
<configuration>
:
<module>
<groupId>com.liferay</groupId>
<artifactId>liferay-portal</artifactId>
<version>${liferayVersion}</version>
<type>war</type>
</module>
:
If I understand things right the artifactId should be "liferay-
portal-lesslibs" else the liferay portal plugin would be the
unmodified liferay war.
I agree, fixed, thanks!
Despite this finding I am unfortunately stuck at the same 404
error at http://localhost:8080/c as pointed out in the
documentation. Although I added the debugviews console portlet
plugin and trying to squeeze some logging out of liferay to find
out what is going on I have so far not been able to get past this
problem.
Have anyone got some luck with this ?
Any suggestion on what to do to get more information out of
liferay/geronimo to be able to pinpoint and fix this error is
greatly appreciated!
I talked with Brian Chan a little bit at JavaOne and it sounded
like liferay had some way to get running on current geronimo, and
he sounded interested in pursuing plugins. However, I haven't been
able to contact him since.
Ah good I will take a look at it. Would it be any point in take the
maven assembling source I have come up with for G 2.1.1 and Liferay
5.0.1 and set it up like the roller plugin? If appropriate I can put
it (zip of the source tree) in a jira hopefully it is just some
minor fixes that is needed for it to run and maybe I (or someone
else) will be able to come up with a running bundle.
I think the ideal situation would be if liferay took over this code as
their geronimo integration. So, maybe opening an issue there with the
code would provoke some movement :-). However if that doesn't work I
think that a geronimo-hosted plugin would be a good idea.

Hi David,
I am glad that this is turning out to be a productive discussion.
I have some more review notes for you.
For reference:
Constructing a special-purpose server using maven
http://cwiki.apache.org/confluence/display/GMOxDOC21/Constructing+a+special-purpose+server+using+maven
[1] Preparation – find the artifacts
[2] Set up a parent maven project
[3] Repackage the liferay war
[4] Build a database plugin
[5] Build the liferay war plugin
[6] Build an assembly
[7] Run the project
Note:
In the following, I use the term "baseline" to mean your liferay-
sample.jar
attached to your wiki doc, which builds as it should in maven
(hence
"baseline"), and "doc" to mean your wiki documentation.
[3] baseline has this:
<version>4.4.1</version>
whereas the doc has this:
<version>${liferayVersion}</version>
which produces an artifact not found error (i.e., there is no
liferayVersion defined at this point of the process).
fixed
[5] baseline has this:
<dependency>
<groupId>com.liferay</groupId>
<artifactId>liferay-portal-lesslibs</artifactId>
<version>${liferayVersion}-SNAPSHOT</version>
<type>war</type>
<scope>provided</scope>
</dependency>
whereas the doc has this:
<dependency>
<groupId>com.liferay</groupId>
<artifactId>liferay-portal-lesslibs</artifactId>
<version>${liferayVersion}</version>
<type>war</type>
<scope>provided</scope>
</dependency>
which produces
[INFO]
------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO]
------------------------------------------------------------------------
[INFO] Failed to resolve artifact.
GroupId: com.liferay
ArtifactId: liferay-portal-lesslibs
Version: 4.4.1
fixed
[6] baseline has this:
<properties>
<geronimoVersion>2.1</geronimoVersion>
</properties>
whereas the mvn command generates this:
<properties>
<geronimoVersion>2.2-SNAPSHOT</geronimoVersion>
</properties>
which produces
[INFO]
------------------------------------------------------------------------
[ERROR] BUILD ERROR

[INFO] Failed to resolve artifact.
GroupId: org.apache.geronimo.assemblies
ArtifactId: assemblies

added a note near the top about this.
[7] I see the same PermGen error.
I wonder if we built this using MySQL rather than the system
database (as
the Liferay folks intended) we would be in better shape?
After all, that database (the MySQL version at least) is just
shy of 60MB,
so it stands to reason that we are taxing resources here.
I would like to explore this. Could you please guide me?
It's worth a try, although it's also a bit worrysome. permGen
OOM errors normally mean you are creating too many classes. The
amount of data being fed into a database shouldn't affect the
number of classes needed so if it is somehow affecting this I
wonder if something else is wrong.
I'll see if I can write up an example later today, but meanwhile
you might look at the mysql plugin for roller under plugins/
roller/trunk. The basic idea is to build another database
plugin, like the derby one but using the mysql wrapper and
include something like this so the mysql plugin gets used instead
of the derby one when it's installed.
<artifact-alias
key="org.apache.geronimo.plugins/roller-derby-database/${version}/
car">org.apache.geronimo.plugins/roller-mysql-database/${version}/
car</artifact-alias>
Apache can't distribute something that automatically downloads
the mysql driver jar which is why the roller plugin has mysql as
a prerequisite. If you are in an environment where this is not a
concern you can leave out the prerequisite and geronimo will
install the mysql jar for you when you install the mysql plugin.
I think I have the basics down of what would be needed, but I
don't think I
quite have it all down yet, and I would like to know for sure by
hearing it
from you.
I think you are getting there, keep asking questions!
I would like to see us put this puppy to bed, you folks bless it
for the
general public, and move on (Liferay portal is but the first of
several apps
I am building on top of Geronimo - details of this project to be
shared as
we go).
looking forward to it!
thanks
david jencks
Thanks!
