请教高手LINUX下JAVA平台的安装,急急急急急急急急急

yanger

我已经在linux上安装了j2sdk1.4.1_04在/usr/java下，php安装后的配置文件如下:
[Java]
;java.class.path = .\ACDecode.jar:.
;java.home = /usr/java/j2sdk1.4.1_04
;java.library = /usr/java/j2sdk1.4.1_04/jre/lib/i386/libjava.so
;java.library.path = =/usr/local/php4/lib/php/extensions/no-debug-non-zts-20020429

extension_dir = /usr/local/php4/lib/php/extensions/no-debug-non-zts-20020429
extension = java.so

重启apache后还是出错，请问高手是怎么回事
我的test.php如下:
<?php
$system=new Java("java.lang.System";
//demonstrate property access
print 'Java version='.$system->;getProperty('java.version').' <br>;';
?>;

出的错误为
Fatal error: Cannot instantiate non-existent class: java in /home/yanger/test.php on line 2

请高手指教，急
