Solr 3.4 Grouping group.main=true results in java.lang.NoClassDefFound
I use drupal for accessing the solr search engine. After updating an
creating my new index everthing works as before. Then I activate the
group=true and group.field=site and solr delivers me the wanted search
results but in Drupal nothing appears just an empty search page. I found
out that the group changes the resultset names. No problem solr offers
for this case the group.main=true parameter. So I added this and get
this 500 error.

I found out that solr didt find the class ArrayUtils.class. I try a lot
of things to get this work. Setting JAVA_HOME and CLASSPATH vars and I
changed the jre without any success. I am really wondering all my other
programms are still running even solr in the "normal" mode is working
and accesibly but not the group.main=true function.
So my question is now what is nessesary to get this work?
Any help is apreciated.
Thx frank

Hey Martijn,
thx for your reply. I tried really a lot, at least I restart the server....
and eh voilá it works as expected. Stupid mistake.
But Martijn I read a lot your postings the last days about the work you have
done. I run into another problem regarding the grouping function including
the counting and numFound value. I think you are the right guy for my
problem.
I open already some tickets in the drupal community and also at JIRA to find
out if its a bug or just another mistake. This problem breaks my project and
I really hope to get some answers.
Please have a look at https://issues.apache.org/jira/browse/SOLR-2817 and
maybe you can help me or give me some suggestions to fix this issue.
Thx Frank

Hi Frank,
How is Solr deployed? And how did you upgrade?
The commons-lang library (containing ArrayUtils) is included in the
Solr war file.
