Custom Plugins for solr
Hi ,
I would like to write a custom component for solr to address a particular
issue.
This is what I have been doing ,write the custom code directly in the
downloaded code base and rebuild the war file and deploy the same. We
currently have multiple cores ,hence I want to approach this in a core
specific way as opposed to affecting all the cores in the webapp .
If I have to write a plugin and move it to the lib directory of each core
,would I just need to add one single class file packed as a jar and make
appropriate changes to the solrconfig file .When I reload the core , I am
assuming that apart from the classes in the war file ,this jar file in the
lib will be automatically referenced.
Would I need to restart sevlet container?
Would I need to have other files to which this custom class is referencing
to in the custom jar file or will that be automatically taken care of?
Regards
Sujatha

Sujatha,
As the API of the classes you're compiling against may have changed
with a different Solr version, it's always a good idea to build
against the new version of Solr, otherwise you might see weird issues
at runtime.
You wouldn't have to do anything special other than to drop your src
file into the new Solr project as you have with this one, recompile,
and rebuild your jar.

Re: Custom Plugins for solr
Posted by Sujatha Arun <su...@gmail.com>.
What I would be doing is this ..
Create a custom class that refer to all org,apache.* classes (import stt)
,the custom file's location is independent of the solr core class files.
compile this separately
package this as a jar
move this to lib dir of each solr core
refer to this in lib directory of solrconfig.xml
realod the core.
I am assuming that I am not directly handling the solr download src files
or the war files ,Is this correct?do I have to be concerned with build
files etc? How then does the approach differ in the later versions?

No, the jar would be exactly the same, with the caveat that you'd have
to build against the newer Solr version of course.

Thanks ,I am going to try this on solr 1.3 version .Would the approach be
any different for the recent sorl versions?

Re: Custom Plugins for solr

Then you're on the right track.
1. You'd either have to restart Tomcat or in the case of Multicore
setups, reload the core.
2. If the jar has dependencies outside of the Solr provided classes,
you'll have to include those as well. If it only depends on Solr stuff
or things that are in the servlet container's classpath, you should be
fine with just the one class.

Hi Sujatha,
Are you adding a new class, or modifying one of the provided Solr classes?
