Call Lucene default command line Search from PHP script
Hello,
My machine is Ubuntu 7.10. I am working with Apache Lucene. I have done with
indexer and tried with command line Searcher (the default command line
included in Lucene package: http://lucene.apache.org/java/2_3_1/demo2.html).
When I use this at command line:
java Searcher -query algorithm
it works and returns a list of results to me. Here 'algorithm' is the
keyword to search.
However, I want to have a web search interface written in PHP, I use PHP
exec() to call this Searcher from my PHP script:
exec("java Searcher -query algorithm ", $arr, $retVal);
[I also tried: exec("java Searcher -query 'algorithm' ", $arr, $retVal)]
It does not work. I print the value of $retVal, it is 1.
I come back and try: exec("java Searcher -query algorithm 2>&1 ", $arr,
$retVal);
I receive:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/lucene/analysis/Analyzer
and $retVal is 1
In the command line Searcher.java of Lucene, it imports many libraries, is
this the problem?
import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.standard.StandardAnalyz er;
....
I guess this is the problem of path. However, I do not know how to fix it
because it works in command line ($CLASSPATH points to the .jar file of
Lucene library). May be PHP does not know $CLASSPATH. So, I add Lucene lib
to $PATH:
export PATH=$PATH:/usr/lib/lucene-core-2.3.1.jar:/usr/lib
However, I get the same error message when I try: exec("java Searcher -query
algorithm 2>&1 ", $arr, $retVal);
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/lucene/analysis/Analyzer
Could you please help?
Thank you,

I meant a shell script that exports the class path, and invokes
java from the same shell.

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:

try using php java bridge
http://php-java-bridge.sourceforge.net/
Its a way for using java objects directly in php.

using command line from PHP is a bad idea.
socket is a better way :
