> I am not really a java developer but this error drives me crazy. All my small programms
are running normal with my java installtion. In the meanwhile i changed the jre and try to
set the CLASSPATH and JAVA_HOME tom get it working but without any success. What is nessesary
to get solr 3.4 running? I see there is obiviously a class missing or not found but how is
this possible if the other solr things are running really well. So any help is apreciated.
