I have been using Solr for several months, but only recently I want to use SolrJ to access Solr.
I can understand most parts in your post, and I really want to have a try of the sc you posted; probably change it somehow to cater my needs. My problem is, I am not sure how to make the sc running. Say I have downloaded apache-solr-3.5.0-src, SolrJ included, where should I put the sc in the package? Can you give some hints or description of steps? Thanks a lot.

However, I am working with Solr for 1 week, and for sure I will encounter some other problems… When this happens I will let you know…

Cheers!

I will now be looking on other tutorials/references for more advanced features! Can you please give some pointers of other documentation? I did not find much about SolrJ.

Just a quick correction on a code snippet you show on the tutorial. There is a variable name (facetEntries) out of place in:
”
List facetEntries = facet.getValues();
”
This is just fine in the file for download.

Thank you! Cheers!

{responseHeader={status=0,QTime=2,params={start=0,q=agencyId:1,wt=[javabin, javabin],rows=1000000,version=2}},response={numFound=1,start=0,docs=[SolrDocument[{agencyId=1, agencyName=Agency One, hostId=2, hostName=Host Two, subOrgId=3, subOrgName=SubOrg Three}]]}}

I want the same string in Json format. Even though I have done query.set(“wt”,”json”), I am getting in this format. Am I doing anything wrong here?

No, I don’t think there’s a way of directly getting the JSONResponse through SolrJ. As far as I can see there’s no way of getting the stream to read from the query or the raw output from the query before parsing in SolrJ.

From what I got from that page, it is only mentioned that if append “wt=json” to the url we will get the response as json. But my problem is how do I get the same json in my java code. Currently I am doing some thing like this.

QueryResponse rsp = solrServer.query(query, SolrRequest.METHOD.POST);
List results = rsp.getBeans(AbstractSolrEntity.class);
String jsonResponse = convertBeansToJson(results);

Instead of doing all this, is there a way to directly get the jsonResponse from the solrServer/QueryResponse?

Thanks,
Anil.

You can use the SolrJSON output writer to get the output from Solr directly as JSON.

Hope that helps!

I want to read the data from Solr in Json format. Is there any way to directly read the Json string (instead of reading the data as Beans & then converting them to Json)?

Thanks,
Anil.
