Compatibility :Liferay 6.1.2 ce ga3 and solr 4.6

Question

Can any one tell me liferay 6.1.2 ce ga3 on tomcat 7 and solr 4.6 on tomcat 7 are compatible?

Used the solr web portlet avaible from liferay market.

I am working on this from last 3 days and i am still getting version issues,executing query issues ,SolrCore 'collection1' is not available issues, CommonsHTTPSolrServer even after following lot of suggestion.

I tried all permutation regarding the jars.

slf4j-api-1.6.6

slf4j-log4j12-1.6.6

slf4j-simple-1.6.6

solr-common-1.3.0

solr-core-4.6.0

solr-solrj-4.6.0

httpclient-4.3.1

httpcore-4.3

httpmime-4.3.1

I also raised this issue on liferay support forum : https://issues.liferay.com/browse/LPS-42758

Answer 1

No they are not compatible (out of the box).
But it is doable, at least it is with Solr 4.4.0 and 4.5.1, so I would guess with Solr 4.6.0 also.

General steps to make it work:

solr-web

• download latest solr-web plugin (source) for 6.1.x
• modify dependacies (see below)
• modify source files (resolve compilation errors)
• modify solr-spring.xml (if needed)
• modify schema.xml (look at both liferay's and solr version, and "merge" (what makes sense) them)

List of jars

• commons-codec-1.6.jar
• commons-io-2.1.jar
• httpclient-4.2.3.jar
• httpcore-4.2.2.jar
• httpmime-4.2.3.jar
• noggit-0.5.jar
• portal-compat-shared.jar
• slf4j-api-1.6.1.jar
• solr-solrj-4.5.1.jar
• wstx-asl-3.2.7.jar
• zookeeper-3.4.5.jar (probably could be removed, I did not)

Additional (provided) jars not packaged in war

• portal-service-6.1.1.jar
• util-java-6.1.1.jar
• servlet-api-2.5.jar

Specifically for CommonsHTTPSolrServer ClassNotFoundException

• in BasicAuthSolrServer constructor you should use HttpSolrServer, instead of CommonsHTTPSolrServer
