Yes you are right.
[code.2] works fine by commenting out the following lines on solrconfig.xml
!--
Used to specify an alternate directory to hold all index data
other than the default ./data under the Solr home.
If replication is in use, this should match the replication configuration.
--
!--
dataDir${solr.data.dir:./solr/data}/dataDir
--
Is it correct this different behaviour from EmbeddedSolrServer ?
Or it can be considered a low priority bug?
Thanks for you prompt reply!
Dino.

Oggetto: Re: EmbeddedSolrServer vs CommonsHttpSolrServer
I suspect this has something to do with the dataDir setting in the example 's
solrconfig.xml
dataDir${solr.data.dir:./solr/data}/dataDir
we use the example's solrconfig.xml as the base for our deployments and always
comment this out
the default of having conf and data sitting under the solr home works well

Subject: EmbeddedSolrServer vs CommonsHttpSolrServer
Hi all,
I am new to solr/solrj.
I correctly started up the server example given in the distribution
(apache-solr-1.4.0\example\solr), populated the index with test data set, and
successfully tested with http query string via browser (es.
http://localhost:8983/solr/select/?indent=onq=videofl=name,id)
I am trying to set up solrj clients using both CommonsHttpSolrServer and
EmbeddedSolrServer.
My examples are with single core configuration.
Here below the method used for CommonsHttpSolrServer initialization:
[code.1]
public SolrServer getCommonsHttpSolrServer() throws IOException,
ParserConfigurationException, SAXException, SolrServerException {
String url = http://localhost:8983/solr;;
CommonsHttpSolrServer server = new CommonsHttpSolrServer(url);
server.setSoTimeout(1000); // socket read timeout
server.setConnectionTimeout(100);
server.setDefaultMaxConnectionsPerHost(100);
server.setMaxTotalConnections(100);
server.setFollowRedirects(false); // defaults to false
// allowCompression defaults to false.
// Server side must support gzip or deflate for this to have any effect.
server.setAllowCompression(true);
server.setMaxRetries(1); // defaults to 0. 1 not recommended.
return server;
}
Here below the method used for EmbeddedSolrServer initialization (provided in
the wiki section):
[code.2]
public SolrServer getEmbeddedSolrServer() throws IOException,
ParserConfigurationException, SAXException, SolrServerException {
System.setProperty(solr.solr.home,
/WORKSPACE/bin/apache-solr-1.4.0/example/solr);
CoreContainer.Initializer initializer = new CoreContainer.Initializer();
CoreContainer coreContainer = initializer.initialize();
EmbeddedSolrServer server = new EmbeddedSolrServer(coreContainer, );
return server;
}
Here below the common code used to query the server:
[code.3]
SolrServer server = mintIdxMain.getEmbeddedSolrServer();
//SolrServer server = mintIdxMain.getCommonsHttpSolrServer();
SolrQuery query = new SolrQuery(video);
QueryResponse rsp = server.query(query);
SolrDocumentList docs = rsp.getResults();
System.out.println(Found : + docs.getNumFound());
System.out.println(Start : + docs.getStart());
System.out.println(Max Score: + docs.getMaxScore());
CommonsHttpSolrServer gives correct results whereas EmbeddedSolrServer gives
always no results.
What's wrong with the initialization and/or the configuration of the
EmbeddedSolrServer?
CoreContainer.Initializer() seems to not recognize the single core from
solrconfig.xml...
If I modify [code.2] with the following code, it seems to work.
I manually added only explicit Core Container registration.
Is [code.4] the correct way?
[code.4]
public SolrServer getEmbeddedSolrServer() throws IOException,
ParserConfigurationException, SAXException, SolrServerException {
System.setProperty(solr.solr.home,
/WORKSPACE/bin/apache-solr-1.4.0/example/solr);
CoreContainer.Initializer initializer = new CoreContainer.Initializer();
CoreContainer coreContainer = initializer.initialize();
/* */
SolrConfig solrConfig = new
SolrConfig(/WORKSPACE/bin/apache-solr-1.4.0/example/solr, solrconfig.xml,
null);
IndexSchema indexSchema = new IndexSchema(solrConfig, schema.xml, null);
CoreDescriptor coreDescriptor = new CoreDescriptor(coreContainer, ,
solrConfig.getResourceLoader().getInstanceDir());
SolrCore core = new SolrCore(null,
/WORKSPACE/bin/apache-solr-1.4.0/example/solr/data, solrConfig, indexSchema,
coreDescriptor);
coreContainer.register(, core, false);
/* */
EmbeddedSolrServer server = new EmbeddedSolrServer(coreContainer, );
return server;
}
Many thanks in advance for the support and the great work realized with all the
lucene/solr projects.
Dino.
