at line :
public static $JAR=$_SERVER['DOCUMENT_ROOT'] .
'/AB2Html/Builder/saxon9he.jar';
i got the error :
Parse error: syntax error, unexpected T_VARIABLE
this is inside a class.
if i test the above line apart, in another script, outside any class, i
get NO error.
then, is that forbiden using such a variable "$_SERVER['DOCUMENT_ROOT'"
inside a class ?
the purpose of using it is to allow my script working on both ubuntu and
Mac OS X.

i put those vars outside of the class like this :
define('JAVA_BIN', '/usr/bin/java');
define('SAXON9HE_JAR', $_SERVER['DOCUMENT_ROOT'] .
'/AB2Html/Builder/saxon9he.jar');
class XSLTSaxonProcessor {
and that works fine...

missing semicolon? in the line before.
/Str.

no, I did verify this point.
in fact i comment out the faulty line and put after it :
public static $JAR='/home/yt/Sites/AB2Html/Builder/saxon9he.jar';
surprisingly the part giving the error, was,for me :
$_SERVER['DOCUMENT_ROOT']
in a class :
<?php
define('JAVA_BIN', '/usr/bin/java');
define('SAXON9HE_JAR', $_SERVER['DOCUMENT_ROOT'] .
'/AB2Html/Builder/saxon9he.jar');
class XSLTSaxonProcessor {
//public static $JAVA='/usr/bin/java';
//public static $DOCUMENT_ROOT = $_SERVER['DOCUMENT_ROOT'];
//$JAR=$_SERVER['DOCUMENT_ROOT'] . '/AB2Html/Builder/saxon9he.jar';
// Parse error: syntax error, unexpected T_VARIABLE in
/home/yt/Sites/AB2Html/Builder/xsltsaxonproc.php on line 5
//public static $JAR='/home/yt/Sites/AB2Html/Builder/saxon9he.jar';
public static $xsl;
public static $xml;
public static $params;
public static $out;
....

You can only initialize a static to a literal. This is not a literal.
You can do it - you just need to do it in the constructor.

I should say a literal or other constant.

this is the offending line

Okay, I can see the error. I suppose it is a limitation of the direct variable
initialization, but I could not find any reference about it.
Put your init code in the constructor in this case.
/Str.

The expression giving the initial value of a proprty must be statically
evaluable and must result to be NULL, FALSE, TRUE, int numbers and simple
operations with int (+ - * / % << >>), float numbers and simple operations with
float (+ - * /), string and string concatenation, other named constants
statically evaluable, or array() with keys and values that are static
expressions as well. Functions and variables like $_SERVER are not allowed
because can be evaluated only at runtime. This same limitation of the PHP
interpreter holds also for: class constants; function default values.
The official manual (http://www.php.net/manual/en/language.oop5.properties.php)
only states:
"This declaration may include an initialization, but this initialization must
be a constant value--that is, it must be able to be evaluated at compile time
and must not depend on run-time information in order to be evaluated."
but now you know the full story.
