Solr : Always seeking for a core named "collection1"

Question

I've created a solr core with configurations and when I try to launch solr embedded server, I get the below error.

Caused by: java.io.IOException: Can't find resource 'solrconfig.xml' in 
 classpath or '/home/tharindu/Desktop/solr_tmp/custom/newsportal/collection1/conf'
    at org.apache.solr.core.SolrResourceLoader.openResource(SolrResourceLoader.java:362)
    at org.apache.solr.core.SolrResourceLoader.openConfig(SolrResourceLoader.java:308)
    at org.apache.solr.core.Config.<init>(Config.java:117)
    at org.apache.solr.core.Config.<init>(Config.java:87)
    at org.apache.solr.core.SolrConfig.<init>(SolrConfig.java:167)
    at org.apache.solr.core.SolrConfig.readFromResourceLoader(SolrConfig.java:145)
    ... 9 more

It seems that it is trying to find a solr core named collection1 by default.

The custom folder contains,

-- solr.xml
-- newsportal
   -- conf
      -- schema.xml
      -- solrconfig.xml
   -- core.properties

I'm using Spring solr template. The EmbeddedServer configuration is below.

    @Bean
    public EmbeddedSolrServerFactoryBean solrServerFactoryBean() {
        EmbeddedSolrServerFactoryBean factory = new EmbeddedSolrServerFactoryBean();
        factory.setSolrHome("/home/tharindu/Desktop/solr_tmp/custom/newsportal");
        return factory;
    }

    @Bean
    public SolrTemplate solrTemplate() throws Exception {
        return new SolrTemplate(solrServerFactoryBean().getObject(), "newsportal");
    }

When I change the EmbeddedServer bean as follows,(only changing the path of the core)

@Bean
public EmbeddedSolrServerFactoryBean solrServerFactoryBean() {
    EmbeddedSolrServerFactoryBean factory = new EmbeddedSolrServerFactoryBean();
    factory.setSolrHome("/home/tharindu/Desktop/solr_tmp/custom");
    return factory;
}

I get the below error.

Caused by: org.apache.solr.common.SolrException: No such core: 
    at org.apache.solr.client.solrj.embedded.EmbeddedSolrServer.request(EmbeddedSolrServer.java:112)
    at org.apache.solr.client.solrj.request.QueryRequest.process(QueryRequest.java:91)

    at org.springframework.data.solr.core.SolrTemplate.execute(SolrTemplate.java:141)
    ... 59 more

But when I rename the core folder as collection1 and change core name in the core.properties to name=collection1, everything works fine.

Below is my schema.xml and solrconfig.xml

Solr version : 4.10.4

Spring solr data version : 1.5.5.BUILD-SNAPSHOT

I appreciate any help to resolve this issue.

Unfortunately, there is no clean approach how to do that because collection1 is harcoded in EmbeddedSolrServerFactory class (corresponding Jira ticket).

But I tried this hacky one and it works for me:

@Bean
public EmbeddedSolrServerFactoryBean solrClient() {
    EmbeddedSolrServerFactoryBean embeddedSolrServerFactoryBean = new EmbeddedSolrServerFactoryBean() {

        @Override
        public EmbeddedSolrServer getObject() {
            return (EmbeddedSolrServer) getSolrClient("<YOUR_CORE_NAME>");
        }
    };

    embeddedSolrServerFactoryBean.setSolrHome("<YOUR_SOLR_HOME");

    return embeddedSolrServerFactoryBean;
}

have a look at this url https://wiki.apache.org/solr/Solr.xml%20(supported%20through%204.x)

To enable support for dynamic SolrCore administration, place a file named solr.xml in the solr.home directory. Here is an example solr.xml file:

<solr persistent="true" sharedLib="lib">
 <cores adminPath="/admin/cores">
  <core name="core0" instanceDir="core0" />
  <core name="core1" instanceDir="core1" />
 </cores>
</solr>

Thus, change the file solr.xml with the an appropriate entry

 <core name="core0" instanceDir="core0" />

Hope this helps

It says **Deprecated in 4.4 and unsupported as of 5.0, see Solr.xml 4.4 and beyond**. I'm using solr 4.10.4 https://wiki.apache.org/solr/Solr.xml%204.4%20and%20beyond – tharindu_DG Aug 22 '16 at 09:12
Sorry about this, I thought that you used version prior to 4.4. – Periklis Douvitsas Aug 22 '16 at 09:14
I have stated that in my question. Anyway thank you for the answer. (Y) – tharindu_DG Aug 22 '16 at 09:15
Can you post your solr.xml that you use? – Periklis Douvitsas Aug 22 '16 at 09:17
Just added. Please check. – tharindu_DG Aug 22 '16 at 09:20
