Re: Jetspeed Questions regarding WebSphere

thank you David for the answers,

I found out that the VersionedPortletApplicationManager is only available in 
2.2 not in the 2.1.3. Then i have tried the 2.2 on WebSphere 6.1.0.25. I 
followed the "EAR deployment" section and still got the class incompatible 
error. The problem is the class in the WebSphere container are loaded as the 
EXT class loader, which is at the top. All the classes we put in the EAR, 
including the portlet api are lower in the hierarchy. In order to load the EAR 
class first,  i will then have to reverse the order of the class loader. That 
could be undesired. Maybe you can help to point me out if i did wrong. And will 
the VersionedPortletApplicationManager work in the 2.1.3?

Another question is that we have the requirements for the user to customerize 
the layout their desktop using drag and drop, i am trying to see if the web 2.0 
based desktop customizer can fit, is there any document on this topic? And i 
assume that once the user changes his layout, it will be a new psml for him, am 
i correct?

thanks/Lance

I am sorry, we don't provide DDL and SQL scripts per database. We prefer to 
generate the DDL from a DB-neutral DDL XML format, and then populate the 
database from also DB-neutral domain-specific XML language. With experience we 
have discovered this process works great once you get past the high learning 
curve of a Maven-2 build. The problem is that people are often so discouraged 
by the build that they simply give up. We have also discovered that at big 
companies, the database teams really prefer to have SQL seed scripts over 
Java-utilities that populate the database over JDBC. Anyway, this is the status 
of things now, so we have to work with it. I could send you the DDL, but then 
we would still have to somehow get you the SQL scripts to populate the basic 
seed data, which is currently not available.

Just to get started with building, take a look at the build guide can be found 
here:

As for why you are receiving the error, Im not sure. That file does not exist 
there. I am not sure why that is happening, as we should be checking against 
Maven remote repositories such as Apache and Bluesunrise first.  I recommend 
another approach: try to build a custom build of Jetspeed as described here:

http://portals.apache.org/jetspeed-2/buildguide/jetspeed-archetype.html

Have you read through the documentation on deploying to Websphere here?:

The default deployment component will have difficulties in a cluster. Recommend 
using an alternate Spring configuration with the 
VersionedPortletApplicationManager:

http://portals.apache.org/jetspeed-2/deployguide/config-overrides.html

I've always disabled J2EE security on the Jetspeed webapp and used Jetspeed's 
internal security directly. Jetspeed does by default use a J2EE Login Module (I 
disable it on Websphere), however I never succeeded in getting it to work with 
Websphere. Im sure if you dig around a bit more you can figure it out
