Solr multicore admin JSP problem on tomcat

[Suman Ghosh <su...@gmail.com>]

I have successfully setup a Solr multicore configuration on Apache Tomcat
5.5 (Solaris 9, JDK 5). I used the 4/21/2008 nightly build for this purpose.
At present, I have two cores defined. I can index and search documents on
both these cores using the java client.

I'm having a minor issue on the Admin interface and I think I might have
missed some configuration steps causing this error. Here is the description
of the error:

1. I use the following URL to successfully browse to the Admin interface of
one of the cores:

http://devbox:8080/solr/solrtest/admin/

2. On the resulting page, I click on the link [SCHEMA]

3. This results in a 404 error. The link to this page is
http://devbox:8080/solr/solrtest/admin/file/?file=schema.xml

4. If I change the link to
http://devbox:8080/solr/solrtest/admin/get-file.jsp?file=schema.xml, the
schema xml is displayed properly.

The same problem happens for the [CONFIG] link.

Can someone please advise me how to fix the issue?

Thanks
Suman

Hmmm... i'm guessing you are using solightly older solrconfig.xml files 
(possibly configs that worked for you in Solr 1.2) and that they do not 
contain a <requestHandler name="/admin/"/> or <requestHandler 
name="/admin/file"/> declaration ... correct?

This isn't specific to multicore ...

the easy workarround is to add this to your solrconfig.xml...

  <requestHandler name="/admin/" class="org.apache.solr.handler.admin.AdminHandlers" />

...it adds handlers for all sorts of cool URLs under the hood (see the 
example solrconfig.xml for more info)
