Hi Erick I was looking the .Java file in the Src folder (... apache-solr-3.4-2011-08-29_18-09-28/solr/solrj/src/java/org/apache/solr/client/solrj/response/QueryResponse.java) to make sure that the method getGroupResponse() exists in the source code.
After adding the Solrj jar file to my buildpath, and importing QueryResponse and GroupResponse classes from it, I was looking for the method getGroupResponse() by doing a Ctrl-Space on my Eclipse IDE, for a QueryResponse class instance. Attaching a screenshot of "ctrl-space", to make myself more clear. As you can see in the screenshot, I can declare an object for GroupResponse class, without getting errors. But, I dont see a getGroupResponse() method for response (which is a QueryResponse object) object. Sowmya.
