Running Solr 1.3 on Weblogic 10 results in the following exception when trying to access the admin page.

This is a compatibility issue resulting in an infinite recursion in the SolrDispatcherFilter. To correct it you need to make the following changes.

1. Create a weblogic.xml file

Create xml file with the following content and save it to solr WEB-INF directory. This is required to disable Solr’s filter on FORWARD.

<?xml version='1.0' encoding='UTF-8'?> 
<weblogic-web-app 
   xmlns="http://www.bea.com/ns/weblogic/90" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
   xsi:schemaLocation="http://www.bea.com/ns/weblogic/90  
    http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">

    <container-descriptor>
       <filter-dispatched-requests-enabled>
          false
       </filter-dispatched-requests-enabled> 
    </container-descriptor> 
</weblogic-web-app> 

2. Remove pageEncoding attribute from solr/admin/header.jsp

The pageEncoding attribute can be found on the first line.
