You have to also pass the classpath to java runtime, not only to javac. If you get this problem within Eclipse, have you tried to cleanup the project, maybe not all files are compiled?
Are you also compiling Lucene from source? If yes, make sure that all Lucene classes are compiled (see cleanup above, uncheck any options to compile only used classes). Lucene uses reflection to load some additional classes not referenced in the .java files directly (dynamic loading), so missing ones would not be seen by javac? Also it may be the case that inside Eclipse you are using the veeeeery old Eclipse-shipped lucene-core.jar that interferes with your program. ----- Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: u...@thetaphi.de > -----Original Message----- > From: Alex vB [mailto:m...@avomberg.de] > Sent: Tuesday, January 25, 2011 5:41 PM > To: java-user@lucene.apache.org > Subject: Re: Could not find implementing class > > > Hello Alexander, > > isn't it enough to add the classpath through -cp?
