Solr Exception when trying to integrate with liferay

Question

I trying to add apache solr 4.6 on window 7 with tomcat 7.

Also i added the solr, solrj and log4j into tomcat lib folder. I copied the solr web porlet into liferay and try to start the server but i am getting exception.

Can anyone tell me what this error is about.

Answer 1

solr-web plugin for liferay 6.1.x is not compatible with solr 4.6, it is compatible with solr 1.4.

If you want to use solr 4.6 you have to modify solr-web. See answer to your other question on this matter.

Answer 2

java.lang.ClassNotFoundException: 
org.apache.solr.client.solrj.impl.CommonsHttpSolrServer at 
org.apache.catalina.loader.WebappClassLoader.loadClass...

This error tells you the class ̀org.apache.solr.client.solrj.impl.CommonsHttpSolrServer wasn't found. There are several possibilities for this kind of error to happen.

1/ This class might be needed for a version of solrj different of the one you put in lib folder or there is a conflict between different version of librairies

2/ Tomcat Lib folder is not taken into account. Make sure this path is valid

3/ Tomcat PATH is not well defined. Startup scripts or executables are there to install paths and configure folders (at least on Linux, but it should be the same on Windows ;-) ). Check you start Tomcat in the recommended way

4/ You have added jars to lib folder and hot re-deployed the app. Restart tomcat for the JVM to take the new jars into account

By the way, these librairies are third party ones that have not to be installed for all Tomcat contexts. I recommend you as a good practice to add them to the webapps lib folder (WEB-INF/lib should do the trick) . You'll then be sure not to have classloader on different branches on the classloader tree.

EDIT : I think this is a problem with your solr/solrj version. I found that in Solrj 4.6 SVN, there is no trace at all of a CommonsHTTPSolrServer I think this class has been dropped since version 4.0 of Solr The code that use the client should be upgraded to Solr 4 or your jar downgraded to 3.6.2 at most
