Hi,

when i start the rake task for solr

like
rake solr:start
i got the following error:

** Invoke solr:start (first_time)
** Execute solr:start
Exception in thread “main” java.lang.NoClassDefFoundError:

Could not find the main class:

Program will exit.

Can anybody tell me what was the problem and how to over come.
