Solr Deployment on Websphere 8.5.5 as WAR application

Question

I am installing solr on WAS 8.5.5 with IBM jdk 7. I deployed the solr as a war and added solr.data.dir and solr.solr.home to custom properties.

Upon accessing the url: http://localhost:9080/solr,

I see the below error on the browser:

Error 500: javax.servlet.ServletException: Filter [SolrRequestFilter]: org.apache.solr.servlet.SolrDispatchFilter was found, but is missing another required class

And the following error in the logs:

SRVE0293E: [Servlet Error]-[com.ibm.ws.webcontainer.extension.DefaultExtensionProcessor]: java.lang.NoClassDefFoundError: org.apache.solr.servlet.SolrDispatchFilter (initialization failure) at java.lang.J9VMInternals.initialize(J9VMInternals.java:176) at java.lang.J9VMInternals.newInstanceImpl(Native Method) at java.lang.Class.newInstance(Class.java:1600) at java.beans.Beans.instantiate(Beans.java:241) at java.beans.Beans.instantiate(Beans.java:89) at com.ibm.ws.webcontainer.filter.WebAppFilterManager._loadFilter(WebAppFilterManager.java:533) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.loadFilter(WebAppFilterManager.java:475) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.getFilterInstanceWrapper(WebAppFilterManager.java:308) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.getFilterChain(WebAppFilterManager.java:380) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.doFilter(WebAppFilterManager.java:892) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.invokeFilters(WebAppFilterManager.java:1025).....

The lib folder of WEB-INF do contain the solr dependencies

Any Help from anybody ?

After scratching my head for 48 hours, finally able to make SOLR up and running on WebSphere.
Looks like the whole fundamental is to understand the class loading strategy on WAS8, and hence choosing the right strategy.

Have enumerated the different steps for solr deployment on WAS 8
