Hi Erick >>does it compile? Are you absolutely sure you've pathed to the proper jar file? Did you check that the jar file that Eclipse is looking at has been rebuilt after you got the new code? -the webapp does not throw compilation errors. The very fact that I am able to declare a GroupResponse class tells me that I am using the new Jar file and not the old one. Solr 3.3's Solrj jar does not have GroupResponse and all its related classes.
>>What ant target did you execute to build the file? -After saying ant dist, a dist directory was created and I took SolrJ jar from that dist directory. >>Has Eclipse re-indexed the contents of the (new) jar file? -Since I was able to declare a GroupResponse object, I think the Eclipse is using the new Jar file..because the Old Jar (3.3) did not have a GroupResponse class at all (which was why I posed this question in this user group, in the first place) Sowmya.
