Hmm, I am not sure if you shouldn't deploy the service again after 
changing the configuration (ant deploy step copies the configuration 
files to destination directory in fact).

Yes, it's much faster, but xmlrpc is still acceptable.

You don't need to change the port number if using eXist DB as WAR. Then 
the port number may be the same. I can see in your configuration you 
still use port 8080 for tomcat.

The port number must be changed if you install eXist as a standalone 
application, because we assume the default port 8080 is already binded 
by Tomcat (LS).

> Could this have anything todo with collection data missing?

Hmm, "ant client-echo" tests 3 things:

1. tries to access DB and get just current data/time from it. It tests 
connection, user account, etc.

2. tries to get collection LSStore

3. tries to get collection LSStore-control

So, even if eXist storage is not configured, pt.1 should work if 
username/password is ok and database is started.


> Here is my service.properties

Well, basically there are two service.properties files.
One is in /home/tijmen/perfsonar-bundle-2.0/XML-LS-1.1.1/perfsonar/conf/
and during "deploy" process is copied to:
/home/tijmen/perfsonar-bundle-2.0/tomcat/webapps/XML-LS-1.1.1/WEB-INF/classes/perfsonar/conf/

It seems to be ok. I assume your user account and password are ok?

I am now in Cambridge and I won't have internet access later on today, 
so I can go back to your problem on Monday.

What I can suggest, you may just remove your installation of LS and try 
to install it from scratch. But I hope you'll find the error before that.

Best regards
