Re: Reading results from FieldCollapsing
Hi Martjin
Sorry for a late response.
I did take the latest Solr build last week.
After the new snapshot, there was a class called grouped response:
(org.apache.solr.client.solrj.response.GroupResponse)
But, the Solrj snapshot (apache-solr-solrj-3.4-SNAPSHOT.jar)'s QueryResponse
class did not have a method: getGroupedResponse().
Is there something I am missing?

Glad you resolved it. I've spent more time than I'd like to admit
trying to get an IDE to play nice!

Re: Reading results from FieldCollapsing
Posted by "Sowmya V.B." <vb...@gmail.com>.
Hi Erick
It was indeed an eclipse issue! Thanks for saying that.
I cleaned the project, restarted eclipse and built again...and I can see the
getGroupResponse() method in the intellisense.
I don't understand why eclipse did that...and what happened in a
restart...but, I now see the method.
Thanks.
Sowmya.

Re: Reading results from FieldCollapsing
Posted by "Sowmya V.B." <vb...@gmail.com>.
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)

Re: Reading results from FieldCollapsing
Posted by Erick Erickson <er...@gmail.com>.
Well, all I can say is that it does show up for me. I use IntelliJ but
that shouldn't
matter.
I suspect there's magic in Eclipse or it's a user error. If you put it
in anyway,
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? What ant target did you execute to
build the file? Has Eclipse re-indexed the contents of the (new) jar file?
Perhaps someone with more Eclipse knowledge than me can chime in.
Best
Erick

Re: Reading results from FieldCollapsing
Posted by "Sowmya V.B." <vb...@gmail.com>.
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.

Re: Reading results from FieldCollapsing
Posted by Erick Erickson <er...@gmail.com>.
How were you looking for it? The QueryResponse class exists, and
the method is available on an instance of that class in an IDE. As I said
I got a copy this morning.
But 'jar tvf apache-solr-solrj-3.4-SNAPSHOT.jar' won't show you the
method, just the class existence.

Re: Reading results from FieldCollapsing
Posted by "Sowmya V.B." <vb...@gmail.com>.
Hi Erick
Both methods don't exist in the jar(apache-solr-solrj-3.4-SNAPSHOT.jar)
file.
I did notice getGroupResponse() method in the QueryResponse.java file in the
src directory though. But, it did not show up in the Jar file I got after
compiling the source.
Sowmya.

I think it's
getGroupResponse, not
getGroupedResponse
I was looking at source I just got this morning...
