Hi,
I have downloaded the code and documentation for Solr version 4.10.3.
I am trying to follow SolrJ Wiki guide and I am running into errors.
The latest error is this one:
Exception in thread "main" org.apache.solr.common.SolrException: No such
core: db
at
org.apache.solr.client.solrj.embedded.EmbeddedSolrServer.request(EmbeddedSolrServer.java:112)
at
org.apache.solr.client.solrj.request.AbstractUpdateRequest.process(AbstractUpdateRequest.java:124)
at org.apache.solr.client.solrj.SolrServer.add(SolrServer.java:68)
at org.apache.solr.client.solrj.SolrServer.add(SolrServer.java:54)
at solr.Test.main(Test.java:39)
My code is this:
package solr;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Collection;
import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.embedded.EmbeddedSolrServer;
import org.apache.solr.common.SolrInputDocument;
import org.apache.solr.core.CoreContainer;
import org.apache.solr.core.SolrCore;
public class Test {
public static void main(String [] args){
CoreContainer container = new
CoreContainer("/Users/carlroberts/dev/solr-4.10.3");
System.out.println(container.getDefaultCoreName());
System.out.println(container.getSolrHome());
container.load();
System.out.println(container.isLoaded("db"));
System.out.println(container.getCoreInitFailures());
Collection<SolrCore> cores = container.getCores();
System.out.println(cores);
EmbeddedSolrServer server = new EmbeddedSolrServer( container,
"db" );
SolrInputDocument doc1 = new SolrInputDocument();
doc1.addField( "id", "id1", 1.0f );
doc1.addField( "name", "doc1", 1.0f );
doc1.addField( "price", 10 );
SolrInputDocument doc2 = new SolrInputDocument();
doc2.addField( "id", "id2", 1.0f );
doc2.addField( "name", "doc2", 1.0f );
doc2.addField( "price", 20 );
Collection<SolrInputDocument> docs = new
ArrayList<SolrInputDocument>();
docs.add( doc1 );
docs.add( doc2 );
try{
server.add( docs );
server.commit();
server.deleteByQuery( "*:*" );
}catch(IOException e){
e.printStackTrace();
}catch(SolrServerException e){
e.printStackTrace();
}
}
}
My solr.xml file is this:
<?xml version="1.0" encoding="UTF-8" ?>

This is an example of a simple "solr.xml" file for configuring one or
more Solr Cores, as well as allowing Cores to be added, removed, and
reloaded via HTTP requests.
More information about options available in this configuration file,
and Solr Core administration can be found online:
http://wiki.apache.org/solr/CoreAdmin
-->
<solr>
<cores adminPath="/admin/cores" defaultCoreName="db">
<core default="true" instanceDir="db/" name="db"/>
</cores>
</solr>
And my db/conf directory was copied from example/solr/collection/conf
directory and it contains the solrconfig.xml file and schema.xml file.
I have noticed that the documentation that shows how to use the
EmbeddedSolarServer is outdated as it indicates I should use
CoreContainer.Initializer class which doesn't exist, and
container.load(path, file) which also doesn't exist.
At this point I have no idea why I am getting the No such core error and
I have googled it and there seems to be tons of threads showing this
error but for different reasons, and I have tried all the suggested
resolutions and get nowhere with this.
Can you please help?
Regards,
Joe
