PHP4调用JavaBean的摸索_PHP
首先声明,写此文时,我对这个也不懂,只是自己从php.net上下了例子,试着做了一下,而且是在 win2000 apache php4p12配置下. 具体步骤如下： 一、安装好JVM(java virtual machine)(我用的是jdk122)
当然，您不一定要用jdk122,甚至不用jdk,用其它的,比如:
JVM=Kaffe 1.0.4 (as delivered with OS), OS=Redhat Linux 6.1
JVM=Kaffe 1.0.5 (built from source), OS=Redhat Linux 6.1
JVM=IBM 1.1.8, OS=Redhat Linux 6.1
JVM=Blackdown 1.2.2 RC4, OS=Redhat Linux 6.1
JVM=Sun JDK 1.1.8, OS=Windows NT 4/win2000
但是,在这里我只讲我的做法,其它的我没有试过,不要问我,这里要特别注意的是, 根据php官方站点的说明,竟然不支持jdk122 linux
二、设置环境变量
在win2000中"我的电脑"->"属性"->"高级"->"环境变量"
设置JAVA_HOME
为:jdk路径,比如我的jdk122装在e:\jsp\jdk122下,那么就设置为e:\jsp\jdk122
三、下载相关文件(如果您没有的话)
下载地址:http://www.php.net/downloads.php
我下载了:php-4.0.1-Win32-java-jdk122.zip文件,解压后有几个例子,并且有:php_java.dll和php_java.jar文件.
四、配置php.ini文件
[java]
java.class.path=E:\PHP4\php_java.jar
java.home=E:\jsp\jdk122\bin
extension=php_java.dll
java.library.path=E:\PHP4\ext\
java.library=E:\Program Files\JavaSoft\JRE\1.2\bin\classic\jvm.dll
以上是我的配置,说明一下,我的php4在e:\php4目录下,我的所有扩充的dll文件 放在e:\php4\ext目录下,当然php_java.dll也就应该copy到这个目录了.最后确认你的 win2000下有jvm.dll文件,如果没有,安装一下visual studio就可以了(我用装了个VC 6,所以不用考虑了)
五、测试
运行phpinfo()就可以看到有"java"了,如果没有，说明你没有成功.它的显示如下:
java
Directive Local Value Master Value
java.class.path
E:\PHP4\php_java.jar E:\PHP4\php_java.jar
java.home
E:\jsp\jdk122\bin E:\jsp\jdk122\bin
java.library
E:\Program Files\JavaSoft\JRE\1.2\bin\classic\jvm.dll jvm.dll
java.library.path
E:\PHP4\ext\ no value
六、测试例子
我用的是下载的文件中包含的例子:jver.php,如果成功,将有如下结果:
Java version=1.2.2
Java vendor=Sun Microsystems Inc.
OS=Windows NT 5.0 on x86
