Default core name in solr 1.4.1 - solr

Question

I cannot set up default core in solr 1.4.1
<cores adminPath="/admin/cores" defaultCoreName="core0">
It doesn't work. The server starts as usual and works but doesn't allow making requests without core name. I went through their release notes and couldn't find when they started supporting this parameter. Does solr 1.4.1 support it? What are the other options?
UPD: The whole solr configs looks this way
<solr persistent="true">
<cores adminPath="/admin/cores" defaultCoreName="core0">
<core name="core0" instanceDir="./core0" />
<core name="core1" instanceDir="./core1" />
</cores>
</solr>
How I check:
1) Check without core(returns HTTP 400 now, "missing solr core name in path")
http://127.0.0.1:8080/solr/select?q=test&version=2.2&start=0&rows=10&indent=on
2) Check with core(response is correct) http://127.0.0.1:8080/solr/core0/select?q=test&version=2.2&start=0&rows=10&indent=on

Answer 1

The answer is No. DefaultCoreName is not supported in solr 1.4.1
I installed solr 3.5 and set up multicore environment, after specifying defaultCoreName I was able to perform the following two requests and the response was the same
http://127.0.0.1:8080/solr/select/?q=solr&version=2.2&start=0&rows=10&indent=on
and
http://127.0.0.1:8080/solr/core0/select/?q=solr&version=2.2&start=0&rows=10&indent=on

Yes it supported in 1.4.
You can try by making it as persistant = true if you want to add more core by the using solr api for managing the core.
If you don't want the default core you can remove it from the xml.
You can have you solr.xml as below and try.
<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="true">
<cores adminPath="/admin/cores" defaultCoreName="collection1">
<core name="collection1" instanceDir="./"/>
</cores>
</solr>
another would be if add your own core by mentioning the data dir and insatance dir..
<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="true">
<cores adminPath="/admin/cores">
<core name="Test" instanceDir="/home/abhijit/Downloads/Solr/" dataDir="/home/abhijit/Downloads/Solr/Test/data"/>
</cores>
</solr>
