Solr 4.3 fails in startup when dataimporthandler declaration is included in solrconfig.xml

Hi, 

I have gotten solr 4.3 up and running on tomcat7/windows7.  I have added the two dataimport handler jars (found in the dist folder of my solr 4.3 download) to the tomcat/lib folder (where I also placed the solr.war).   

Then I added the following line to my solrconfig.xml:

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
    <lst name="defaults">
      <str name="config">dih-config.xml</str>
    </lst>
</requestHandler>

When I start tomcat, I get the stack trace shown below (commenting out the above lines causes tomcat & solr to start up just fine).

Re: Solr 4.3 fails in startup when dataimporthandler declaration is included in solrconfig.xml

Posted by William Pierce <ev...@hotmail.com>.
I got this to work (thanks, Jan, and all).  It turns out that DIH jars need 
to be included explicitly by specifying in solrconfig.xml or placed in some 
default path under solr.home.  I placed these jars in instanceDir/lib and it 
worked.  Previously I had reported it as not working - this was because I 
had mistakenly left a copy of the jars under tomcat/lib.

My question was: When you move DIH libs to Solr's classloader (e.g. 
instanceDir/lib and refer from solrconfig.xml), and remove solr.war from 
tomcat/lib, what error msg do you then get?

Also make sure to delete the old tomcat/webapps/solr folder just to make 
sure you're starting from scratch

Re: Solr 4.3 fails in startup when dataimporthandler declaration is included in solrconfig.xml

Posted by William Pierce <ev...@hotmail.com>.
The reason I placed the solr.war in tomcat/lib was -- I guess -- because 
that's way I had always done it since 1.3 days.  Our tomcat instance(s) run 
nothing other than solr - so that seemed as good a place as any.

The DIH jars that I placed in the tomcat/lib are: 
solr-dataimporthandler-4.3.0.jar and 
solr-dataimporthandler-extras-4.3.0.jar.  Are there any dependent jars that 
also need to be added that I am unaware of?

On the specific errors - I get a stack trace noted in the first email that 
began this thread but repeated here for convenience:

Why did you place solr.war in tomcat/lib?

Can you detail the specific errors you get when you place your DIH jars in 
solr-home/lib or instanceDir/lib?

I'd say it is still a CLASSPATH issue. Quick Google shows long history
of complaints (all about Tomcat):

Thanks, Alex.  I have tried placing the jars in a folder under solrhome/lib 
or under the instanceDir/lib with appropriate declarations in the 
solrconfig.xml.  I can see the jars being loaded in the logs.  But neither 
configuration seems to work.

Could be classloader issue. E.g. the jars in tomcat/lib not visible to
whatever is trying to load DIH. Have you tried putting those jars
somewhere else and using "lib" directive in solrconfig.xml instead to
point to them?
