[TYPO3-Solr] Error loading class 'org.typo3.solr.search.AccessFilterQParserPlugin'

[Peter Kraume]

Hi folks,

I used the shell script, that is shipped with tx_solr to install tomcat 
and solr.

But there seems to be a problem with the TYPO3 access filter plugin:

HTTP Status 500 - Severe errors in solr configuration. Check your log 
files for more detailed information on what may be wrong. If you want 
solr to continue after configuration errors, change: 
<abortOnConfigurationError>false</abortOnConfigurationError> in null 
------------------------------------------------------------- 
org.apache.solr.common.SolrException: Error loading class 
'org.typo3.solr.search.AccessFilterQParserPlugin' at 
org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:375) 



solrconfig name is tx_solr-1-7-0--20110412

typo3lib dir is where it' specified:
<lib dir="../typo3lib/" />
/opt/solr-tomcat/solr/typo3lib
In this directory the file typo3-accessfilter-1.1.0.jar resides.

Regarding the error message, solr can't find the plugin, but I have no 
idea why. Any ideas?

Cheers
Peter
