Milu, This is a PHP problem, not a Lucene one, so you might get better response at a PHP mailing list.
The easy way around your problem is probably by invoking a shell script from php that exports the class path as you indicated, so that java can see the correct classes. Having said that, you'll probably want to use the PHP/Java extension to avoid initializing a JVM for each call to lucene. Try this: http://www.google.nl/search?q=php+java+org+apache+lucene&ie=UTF-8&oe=UTF-8 This was one of the results: http://www.idimmu.net/index.php?blog%5Bpagenum%5D=3 Regards, Paul Elschot Op Friday 21 March 2008 21:24:37 schreef milu07: > Hello, > > My machine is Ubuntu 7.10.
