DataImportHandler on Websphere - http response 404

2011-01-12 Thread chrisclark 

Has anyone had any success using the DataImportHandler on Webshpere 6.1

Below are the logs for a call to reload-config.
I have turned on debug and stepped through the code and the
dataImportHandler correctly reloads the config and the response gets written
out to the http response without any errors being thrown from the Solr code.
However, in Websphere the response is returned as a 404 page not found. So
this is happening somewhere in the Websphere code.
There are no errors reported in any of the Websphere logs.

This all works fine on JBoss but doesn't work on Websphere.
The version of Solr is 1.4.1
Websphere is: 
version 6.1.0.0 
Build Number: b0620.14
Build Date: 5/16/06


This is the log file snippet.

Re: DataImportHandler on Websphere - http response 404

2011-01-12 Thread chrisclark 

I have found a workaround for this.

1. change the entry in solrconfig.xml for the DataImportHandler by removing
the slash from the name, like this requestHandler name=dataimport...

2. when making the request to the SolrJ server, don't use a slash in the qt
parameter, i.e.
solrParameters.set(qt, dataimport);

If you use slashes, the url generated by SolrJ will be like
'/solr/dataimport...qt=%2Fdataimport'
Removing the slashes will change the url to something like
'/solr/select...qt=dataimport'
(Solr will use the 'qt' parameter to find the right handler).

The resulting url will be something like this:
/solr/select?optimize=trueclean=falsecommit=truecommand=reload-configqt=dataimportwt=javabinversion=1

My guess is that '/select' is mapped in the web.xml of Solr to a servlet,
whereas '/dataimport' is not and that Websphere will complain about that,
whereas JBoss doesn't care.
