MMBase and Liferay

[Robin Vanspauwen]

Hello,

Some people at the Open University want to work with Liferay (possible
substitute for Microsoft Sharepoint) but I keep having problems
installing or configuring Liferay and MMBase applications on one
Tomcat server. When I deploy Liferay on a Tomcat server with existing
MMBase webapps, the MMBase webapps die and Liferay works… For Liferay
to work I have to copy three JAR’s in the lib directory of Tomcat;
jta.jar (from oracle/sun), portal-service.jar (from liferay) and
portlet.jar (from liferay).

I get this error for example:

Can you send me these jars? Then I'll give it a try too.

Hi Michiel,

MMBase will start if you copy these three JAR's to the lib dir of Apache
Tomcat. But when I copy the liferay webapp into the webapps dir of Apache
Tomcat, the other MMBase applications die...

Greets,

Robin

Probably it is a better idea to package your application, MMBase-jars and more extra jars into a decent WAR-file, and copy it to the 'deploy' folder of Liferay. It will auto-redeploy it when running, and current Liferay libraries are used too. Otherwise you might also get class loading problems.

So, in that case I can't actually reproduce it without also having
such a liferay webapp. That makes it a bit more difficult.

Well, the exception suggest that BodyContext#getReader()
(http://download.oracle.com/javaee/1.2.1/api/javax/servlet/jsp/tagext/BodyContent.html#getReader())
returned null. I have no idea what kind of sense that makes. Javadoc
does not suggest that this should be possible at all.

Could you give the simplest Jsp that would give the exception. E.g.
<mm:content postprocessor="none">
foo
</mm:content>
or
<mm:content postprocessor="text/html">
foo
</mm:content>
or
<mm:content postprocessor="text/html" />

or would they all do it?

Anyhow. Simplest would be to add a check on 'null' there. Perhaps
getString would not return null in those cases?

When I package my MMBase application into a WAR file using 'jar -cvf
application_name.war *' and deploy it in the deploy directory of
Liferay (automatically trough Liferay), I get the following error when
I want to open a:

When I start the Apache Tomcat server with MMBase apps and a Liferay
app, I can view the basic admin environment of MMBase. I can see the
application_name/mmbase/ page. But when I want to open the my_editors
I get the same error as before.

[Jacobjob Koster]

And you defined your MMBase servlets properly inside the web.xml file?
Additional to the default Liferay servlets, of course?
The order might be important btw.

PS. Maybe add the stack traces as an attachment; now they get wrapped
for every line.

[Robin Vanspauwen]

I have attached the web.xml of the MMBase application. Most of the xml is generated. Maybe you can have a quick look at it?

Thanks!
