Solr indexing fails on server.request(up) - solr

Question

while indexing into solr, i am getting an error like this.
HTTP Status 500 - lazy loading error
org.apache.solr.common.SolrException: lazy loading error at
org.apache.solr.core.RequestHandlers$LazyRequestHandlerWrapper.getWrappedHandler(RequestHandlers.java:260)

The URL formed is : http://localhost:8080/solr/update/extract?Latitude=51.9125&Longitude=179.5&commit=true&waitFlush=true&waitSearcher=true&wt=javabin&version=2
(I have configured tomcat using Xampp on Windows machine)
I have been following SOF and various other blogs/forums and tried to debug it but for hours i could not find anything.
I have added the following things in the solr.xml
<maxFieldLength>10000</maxFieldLength>
<writeLockTimeout>60000</writeLockTimeout>
<commitLockTimeout>60000</commitLockTimeout>
<lockType>simple</lockType>
<unlockOnStartup>true</unlockOnStartup>
<reopenReaders>true</reopenReaders>
<requestParsers enableRemoteStreaming="true"
multipartUploadLimitInKB="2048000" />
<lst name="defaults">
<!--str name="echoParams">explicit</str-->
<!--int name="rows">10</int-->
<!--str name="df">text</str-->
<str name="Latitude">Latitude</str>
<str name="Longitude">Longitude</str>
</lst>
Even tried adding the following to solconfig.xml ands restarting tomcat i get
<requestHandler name="/update/extract" class="org.apache.solr.handler.extraction.ExtractingRequestHandler">
<lst name="defaults">
<str name="ext.map.Last-Modified">last_modified</str>
<bool name="ext.ignore.und.fl">true</bool>
</lst>
</requestHandler>
On the Java console it shows an error :
org.apache.solr.common.SolrException: Internal Server Error
I realized the issue might be because of my solr home path. I created a new directory and copied all the config files there and mentioned that as my solr path. However, I later update the solrconfig.xml, correcting paths for all the jars.
Also tried adding the 'pdfbox and fontbox' jars in to solr lib folder and restarting Tomcat
My Java code is :
String urlString = "http://localhost:8080/solr";
SolrServer server = new CommonsHttpSolrServer(urlString);
ContentStreamUpdateRequest up = new ContentStreamUpdateRequest("/update/extract");
String fileName=f.toString();
up.addFile(new File(fileName));
up.setParam("Latitude", Latitude);
up.setParam("Longitude", Longitude);
up.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);
server.request(up);
(Port8080 is the one i have configured)
Still solr indexing is not working at my end.. i have tried hours debugging this and figuring out. It would be really great if you can show me some hint or suggest anything i am doing wrong.
As for your ref i have already tried :

How to index pdf's content with SolrJ?

Answer 1

Finally I find a way to solve this.
Just modify SOLR_HOME/conf/solrconfig.xml, change all the dir attribute of <tab> tag from "../../dist/" to "../dist/", save the file
If you encounter this problem, that the solr directory must be move from apache-solr-x.x.x\example to some other place, so the relative path "../../dist/" need to be changed accordingly.
Remember to restart your tomcat and see if it work.

Answer 2

Do you have solr-cell.jar in your class path. ?
The ExtractingRequestHandler is in the solr-cell.jar, which is not packaged with the default solr-server
