[TYPO3-Solr] Problems with multicore setup

[Peter Kraume]

Based on a JiffyBox with TYPO3-Image (Ubuntu 10.04 LTS) I tried to 
create a multicore setup.

My solr.xml looks like this (like Ingo suggested in the Solr Wiki[1]):
<core name="dev-FooBarGermany-1-0-en_US" instanceDir="typo3cores" 
schema="english/schema.xml" dataDir="data/dev-FooBarGermany-1-0-en_US" />
<core name="dev-FooBarGermany-1-1-de_DE" instanceDir="typo3cores" 
schema="german/schema.xml" dataDir="data/dev-FooBarGermany-1-1-de_DE" />
[...]

But I get a 404 error upon using Solr like this:
http://xxx.xxx.xxx.xxx:8080/solr-foobar/dev-FooBarGermany-1-0-en_US/select?q=
or like this:
http://xxx.xxx.xxx.xxx:8080/solr-foobar/dev-FooBarGermany-1-0-en_US/admin

When I remove the core name from  the URL, I get this error message: 404 
- missing core name in path
So I assume that Solr already knows about the multicore setup.

When I call Solr like this:
http://xxx.xxx.xxx.xxx:8080/solr-foobar/admin/cores
I get this response:
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader"><int name="status">0</int><int 
name="QTime">0</int></lst><lst name="status"/>
</response>

Unfortunately, the logs in /var/log/tomcat6 don't provide any useful 
information. Solr version is 1.4.0.

I appreciate any hints since I'm working on this since days with no success.

Cheers
Peter
