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
