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?

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?
Regards,
Alex.

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).
