Multiple instances, wiki out of date?

Mon, 26 Feb 2007 10:53:38 -0800 

Hi there,
I've been following the instruction from http://wiki.apache.org/solr/SolrJetty?highlight=%28Multiple%29%7C%28Solr%29%7C%28Webapps%29solr to get a few indexes running under the same instance of jetty 6.1.2. If I use the webapp descriptors as specified in the wiki (with correct paths, I'm just pasting the example here).. 

<Call name="addWebApplication">
 <Arg>/*solr*1/*</Arg>
 <Arg>/your/path/to/the/*solr*.war</Arg>
 <Set name="extractWAR">true</Set>

 <Set 
name="defaultsDescriptor">org/mortbay/jetty/servlet/webdefault.xml</Set>

 <Call name="addEnvEntry">
   <Arg>*solr*/home</Arg>
   <Arg type="String">/your/path/to/your/*solr*/home/dir</Arg>
 </Call>
</Call>

<Call name="addWebApplication">
 <Arg>/*solr*2/*</Arg>
 <Arg>/your/path/to/the/*solr*.war</Arg>
 <Set name="extractWAR">true</Set>

 <Set 
name="defaultsDescriptor">org/mortbay/jetty/servlet/webdefault.xml</Set>

 <Call name="addEnvEntry">
   <Arg>*solr*/home</Arg>
   <Arg type="String">/your/path/to/your/alternate/*solr*/home/dir</Arg>
 </Call>
</Call>

Jetty complains that:

I've been looking at the Jetty API and it looks like those methods are 
deprecated in the latest versions of Jetty. Anyway, I can get several 
instances to run together using the descriptor shown below and several 
war files


<Call name="addLifeCycle">
 <Arg>
   <New class="org.mortbay.jetty.deployer.WebAppDeployer">
     <Set name="contexts"><Ref id="Contexts"/></Set>

     <Set name="webAppDir"><SystemProperty name="jetty.home" 
default="."/>/webapps-plus</Set>

     <Set name="parentLoaderPriority">false</Set>
     <Set name="extract">true</Set>
     <Set name="allowDuplicates">false</Set>

     <Set name="defaultsDescriptor"><SystemProperty name="jetty.home" 
default="."/>/etc/webdefault.xml</Set>

   </New>
 </Arg>
</Call>


This is good enough for me but the problem then is that all point to the 
same data/index folder sharing the same index and I need them to use 
different indexes. The question is, how can you configure solr.home 
differently for each of the solr instances deployed in the webapps-plus 
folder?



It would be equally valid if there is a way of fixing the xml in the 
wiki so individual war files can be specified passing a different 
solr.home to each..


thanks,

galo.
