I believe that is correct. When you shutdown it writes the xreg files out to disk,
however:
the following may also be true:
User starts Jetspeed.
User makes changes to xreg files
Registry runs is filewatcher, sees the change, and loads the changes.
If the server is shutdown at this point it may write the changes back to the file
system. I have not verified this however.
Check the Registry service entry in JR.props.
#########################################
# Registry Service #
#########################################
services.Registry.classname=org.apache.jetspeed.services.registry.CastorRegistryService
services.Registry.directory=/WEB-INF/conf/novus/
services.Registry.mapping=/WEB-INF/conf/novus/registry.xml

Also if you are interested in some code to view the Registry here is a code snippet
Enumeration registryEntrys =
org.apache.jetspeed.services.Registry.getNames();
while (registryEntrys.hasMoreElements())
{
String regEntry = (String)registryEntrys.nextElement();
System.out.print(regEntry);
Registry reg =
org.apache.jetspeed.services.Registry.get(regEntry);
System.out.println(" : " + reg.toString());
RegistryEntry entry[] = reg.toArray();
for (int i = 0; i < entry.length; i++)
{
RegistryEntry registryEntry = entry[i];
System.out.println("\t" + registryEntry.getName());
}
}

Subject: RE: configuration files (xreg) destroyed after shutdown
Hi
I also have been trying to understand how the xregs work.
If I understand correctly, Jetspeed has a filewatcher process sitting on top
of the xregs, so that for example if I add a new portlet, the filewatcher
would detect the change and load the new portlet. This is great because it
means that I can tweak the xregs without having to restart Jetspeed.
However Jetspeed also flushes the xregs from memory to disk on shutdown, and
without invoking filewatcher first. This means that any manual changes I
made since the last time filewatcher loaded the file will get clobbered.
Can anyone tell me if this is correct?
Ray

Thanks for your quick answer!
How exactly do you do this? I usually shut down tomcat using the
automatically provided menu-item which does this by calling
java.exe -jar -Duser.dir="C:\Programme\Apache Group\Tomcat 4.1.12"
"C:\Programme\Apache Group\Tomcat 4.1.12\bin\bootstrap.jar" stop
I see the possibility of each time stopping jetspeed using the tomcat
management application prior to stopping tomcat itself. Is that what you
suggest?

Betreff: Re: configuration files (xreg) destroyed after shutdown
Hello I know the problem, but itīs not that bad actually. What happens?
When you start a shutdown process the xregs are written onto the config
directory as it seems. Well if you kill the shutting down process some
of the xregs arenīt written properly and left empty.
The solution at least in my case was not to kill tomcat during the
shutdown process but giving it enough time to shut down propery and
kill itself after everything ist done. At least that did the trick to me
on Tomcat 4.1
