3)copy jar files c:\downloads\solr-5.2.1\solr-5.2.1\dist\solrj-lib directory c:\downloads\apache-tomcat-7.0.62\apache-tomcat-7.0.62\lib directory.

4) create solr.xml in c:\downloads\apache-tomcat-7.0.62\apache-tomcat-7.0.62\conf\catalina\localhost folder.

<?xml version='1.0' encoding='utf-8'?> <context docbase="c:/downloads/apache-tomcat-7.0.62/apache-tomcat-7.0.62/webapps/solr.war" debug="0" crosscontext="true" >     <environment name="solr" type="java.lang.string" value="/apache-tomcat-7.0.62/webapps/" override="true"></environment> </context>

6)start tomcat using startup.bat command in bin folder

7)edit web.xml to

  <env-entry>        <env-entry-name>solr/home</env-entry-name>        <env-entry-value>c:/downloads/solr-5.2.1/solr-5.2.1</env-entry-value>        <env-entry-type>java.lang.string</env-entry-type>     </env-entry>

8)restart tomcat , hit url http://localhost:8080/solr 404 not found error.the error in console 

severe: error deploying configuration descriptor c:\downloads\apache-tomcat-7.0. 62\apache-tomcat-7.0.62\conf\catalina\localhost\solr.xml java.lang.nullpointerexception         @ org.apache.catalina.startup.hostconfig.deploydescriptor(hostconfig.ja va:645)

the solr wiki states running 5.x versions on tomcat no longer supported:

internally, solr still implemented via servlet apis , powered jetty -- implementation detail. deployment "webapp" other servlet containers (or other instances of jetty) not supported, , may not work in future 5.x versions of solr when additional changes made solr internally leverage custom networking stack features.
