Not necessarily, you can create another repository file, say myapp_respository.xml, \
and link it like jetspeed_repository.xml is within the base respository.xml. \
However, the jetspeed_respository.xml IS NOT jetspeed 1 compatible it is meant for \
the JSR-168/J2 implementation. So, you will probably need to write the repository \
for J1 yourself, which should not be that big of a deal as you have some good \
examples already and the OJB site, http://db.apache.org/ojb, has great documentation. \
I already started this by using OJB to manage all the security persistence operations \
as opposed to using Torque. However, I just used straight OJB to do it instead of \
the plugin (don't ask me why, I just did ;). The change became bigger than expected, \
as I have totally re-implemented security using an event model where multiple events \
can contribute to login, logout, role check, get users. Etc. Allowing me to have \
security checks originating from multiple sources and systems.

The persistence plugin does not do this automatically, you would need to implement a \
db psml service that uses the plugin architecture.

Hi Scott, thanks for the point in this direction. I took this offline because I \
don't know how much of this you want in the user list before your how-to is \
finished...feel free to move this back to the list, I just didn't want to generate \
unnecessary questions for you. I feel like I may be close to getting this to work. \
I had already downloaded the source when I got your message, and here's the stuff I \
have done so far:

Web Content changes
-------------------
added Web Content/WEB-INF/conf/ojb/OJB.properties
added Web Content/WEB-INF/conf/ojb/repository.dtd
added Web Content/WEB-INF/conf/ojb/repository.xml
added Web Content/WEB-INF/conf/ojb/repository_database.xml
added Web Content/WEB-INF/conf/ojb/repository_internal.xml

Jar files
---------
added db-ojb-1.0.rc4.jar
Configuration changes
---------------------
modified JetspeedResources.properties to configure persistence service
modified persistence-plugins.xml to use persistence-plugins.dtd
modified persistence-plugins.dtd to reflect structure of persistence-plugins.xml
modified /ojb/repository_database.xml to use Oracle
Now I think I am stuck again. :) I have looked at the \
WEB-INF/db/hsql/Registry.script file and I am confident that I can get the right \
tables, etc. in my oracle database. However, when I look at the \
repository_jetspeed.xml it looks like I need to add all the classes referenced in \
there to my project as well. Is this correct? Also, I think I'm missing the place \
where I actually tell Jetspeed to use the database as the persistence mechanism \
rather than the file system. Or, is it an automatic switch when it doesn't find the \
files?
If there is any way I can help in putting this how-to together, please let me know. \
Thanks again for your time.
-Mike

Hi Mike,
I don't currently have any documentation put together on using the persistence plug \
in standalone. I should have some time this weekend to put together a how-to on \
using the persistence plug in a standalone application. I the mean time, you can \
checkout J2 from the CVS, you can start looking at the code under plugin/src. You \
can also look in portal/src/webapp/WEB-INF/conf/jetspeed.properties to see how the \
service is configured. Look at \
portal/src/webapp/WEB-INF/conf/persistence-plugins.xml on how to define a plugin \
instance(s). portal/src/webapp/WEB-INF/conf/ojb contains all the standard OJB \
information for the OJB-based plguins.
hth,
