Null RequestHandler null.

register is as follows
<requestHandler name="/custom" class="org.apache.solr.my.MyCustomHandler">

the request must be made to the uri "/custom" only then the requests
would come to your handler

Then also,
In statistics page, my custom handler under QueryHandler's request count
remains 0. It shows that, the webrequest is not coming to my class....

register your handler in some other name and fire a request to that

I solved this NullPointerException, by the following changes.

In java code:
public void handleRequestBody(SolrQueryRequest request, SolrQueryResponse
response) throws Exception {
SolrCore coreToRequest =
request.getCore();//coreContainer.getCore("core2");
.....
}

and in solr-config.xml:
<requestHandler name="/select" class="solr.my.MyCustomHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<str name="q">tandem</str>
<str name="debugQuery">true</str>
</lst>
</requestHandler>

Now, my webapp runs fine by,
http://localhost:8983/mysearch
searching also working fine.
But, these are not run through my custom handler. So i felt, it wrongly
doing searching.
Because, in solr admin statistics page,
my custom handler under QueryHandler's request count remains 0, it
doesn't
get incremented, when i search something. Rather, statndardReqHandler's
request count is incremented.

And another thing, how do we debug solr. ???
Please anybody help me to solve this ...

Thanks in advance.

hi,
 i am new to apache solr.
I need to create a custom request handler class. So i create a new one
and
changed the solr-config.xml file as,
 <requestHandler name="/select" class="solr.my.MyCustomHandler">
    <lst name="defaults">
        <str name="echoParams">explicit</str>
        <str name="q">tandem</str>
        <str name="debugQuery">true</str>
    </lst>
 </requestHandler>

And in my java class, the code is,

public class MyCustomHandler extends RequestHandlerBase{
 public CoreContainer coreContainer;
 public void handleRequestBody(SolrQueryRequest request,
SolrQueryResponse
response) throws Exception {
    SolrCore coreToRequest = coreContainer.getCore("core2");
    ModifiableSolrParams params = new ModifiableSolrParams();
    params.set("echoParams", "explicit");
    params.set("q", "text");
    params.set("debugQuery", "true");
request = new LocalSolrQueryRequest(coreToRequest, params);
//             SolrRequestHandler reqHandler =
coreToRequest.getRequestHandler("/select");
    coreToRequest.execute(reqHandler, request, response);
    coreToRequest.close();
    request.close();
 }
 // the abstract methods - getDescription(), getSourceId(),
getSource(),
getVersion() are //overrided... but these methods doesn't have any
implementations.
}


But, if i search any text in my webapp from browser, gots the HTTP 500
error.
i dont know how SolrContainer is intialized....
Pls anyone give me the solution...

thanks and regards,
Mohamed
