[TYPO3-Solr] Suggest Search Fatal Error

[Daniel Vogt]

I have problems with the suggest search. The "normal" search works well, 
but the suggest request returns a Fatal Error.

request-parameters:
eID=tx_solr_suggest&term=abo

response:
Fatal error: Call to a member function getRawResponse() on a non-object 
in SERVERNAME/typo3conf/ext/solr/eid_suggest/suggest.php on line 69

I installed the newest version of that file from the svn trunk that gave 
me more output in the devlog:

exception 'Apache_Solr_HttpTransportException' with message ''500'

As it seems it has something to do with Java, has it?
