I'm not able to integrate Solr 7.5 with AEM 6.4,

getting the following error:

I have tried with almost every version of Solr, but I am getting the same error again and again!

I am simply following this tutorial:

Adobe Experience Manager Help | Integrating SOLR with Adobe Experience Manager

But, in this tutorial, apache.felix.scr.annotations are used. I am just replacing these annotations with osgi annotations.

Here is the new article with R6 annotations working - along with a video. 
Adobe Experience Manager Help | Integrating SOLR with Adobe Experience Manager 6.4 
@Component
public class SolrSearchServiceImpl implements SolrSearchService 
One difference here is we show new way of reading OSGi config values for this use case. This involves these annotations: 
package com.adobe.aem.core;
import org.osgi.service.metatype.annotations.AttributeDefinition;
import org.osgi.service.metatype.annotations.AttributeType;
import org.osgi.service.metatype.annotations.ObjectClassDefinition;
  
@ObjectClassDefinition(name = "AEM Solr Search - Solr Configuration Service", description = "Service Configuration")
public @interface MySimpleService {
      
    @AttributeDefinition(name = "Protocol", defaultValue ="http", description = "Configuration value")
    String protocolValue();
     
     
    @AttributeDefinition(name = "Solr Server Name", defaultValue ="localhost", description = "Server name or IP address")
    String serverName();
     
    @AttributeDefinition(name = "Solr Server Port", defaultValue ="8983", description = "Server port")
    String serverPort();
     
    @AttributeDefinition(name = "Solr Core Name", defaultValue ="collection", description = "Core name in solr server")
    String serverCollection();
     
    @AttributeDefinition(name = "Content page path", defaultValue ="/content/we-retail", description = "Content page path from where solr has to index the pages")
    String serverPath();
      
}

Please check the dependency version of solrj.

You can check the version by giving the package here - /system/console/depfinder

The article you referenced is for AEM 6.2. I am gonig to test this on 6.4 and we will update the article. Updating the OSGi to R6 and the dependencies will be part of this updated article.

<dependency>
<groupId>org.apache.solr</groupId>
<artifactId>solr-solrj</artifactId>
<version>7.5.0</version>
</dependency>

Is this the Maven dependency you are using ? I tried it but the jars are not reflecting in my build . Could you share the maven dependency you used. I can try it out and check

Thanks

Hi Mayanky,

If you simply follow this tutorial and install the package with SCR annotations, it does work even on AEM 6.4 SP2.

At least to the point where you can see the bundle started. Following services are registered as well:

Service ID 8543	Types: com.adobe.aem.core.SolrServerConfiguration Service PID: com.adobe.aem.core.impl.SolrServerConfigurationImpl Component Name: com.adobe.aem.core.impl.SolrServerConfigurationImpl Component ID: 4256 Vendor: Adobe
Service ID 8544	Types: javax.servlet.Servlet Service PID: com.adobe.aem.core.servlets.DeleteIndexesFromSolr Component Name: com.adobe.aem.core.servlets.DeleteIndexesFromSolr Component ID: 4257 Vendor: Adobe

Service ID 8549	Types: org.apache.sling.spi.resource.provider.ResourceProvider Description: ServletResourceProvider for Servlets at [/bin/solr/push/pages.servlet, /bin/solr/push/pages]
Service ID 8550	Types: org.apache.sling.spi.resource.provider.ResourceProvider Description: ServletResourceProvider for Servlets at [/bin/solr/push/pages.servlet, /bin/solr/push/pages]

The tutorial itself uses Solr version 5.4.1. It adds Solr jar as a jar in class path:

Bundle Classpath.,OSGI-INF/lib/org.apache.servicemix.bundles.solr-solrj-5.4.1_1.jar,OSGI-INF/lib/log4j-1.2.16.jar,OSGI-INF/lib/noggit-0.5.jar,OSGI-INF/lib/zookeeper-3.4.5.jar

Which should allow you to work. So, in your case, to upgrade it to Solr 7, you would need to update your pom.xml to Solr 7 Jar's (including all of the new Jar's that need to be included in classpath for Solr 7).

Regards,

Peter

Dear Mayanky,

Please find patch that updates SolrJ library to 7.5.0. This code stil uses SCR, only the changes needed to update SolrJ library bundled here to 7.5 have been performed.

This will be part of the new article - need to test front end logic now.
