lajp 实现php高效调用java
http://blog.chinaunix.net/uid-20767210-id-1849682.html

轻量级框架,非常好用,且线程交互,非常高效,在复杂的项目都可以寅刃尔解.

具体实现过程:

1.下载lajp的包,地址http://code.google.com/p/lajp/,解压缩,然后修改make.sh文件,把里面的java_home修改过后,make过后,把里面的so文件copy到java的库(java.library.path)文件任意目录下面。
2.然后到java的目录下启动run_msgq.sh,
  注意如果用到了第三方包的话一定要在此处的classpath里面引用,相对路径也可以。用命令nohup ./run.sh & 后台启动

3.在/var/www/html/health/下面新建一个testphpjava.php,内容如下:

require_once("php_java.php");  //引用下载的php_java.php文件

$name = "Ali";

try
{
  //调用Java的hello.HelloClass类中的hello方法
  $ret = lajp_call("hello.HelloClass::hello", $name);
  echo "{$ret}
";
}
catch (Exception $e)
{
  echo "Err:{$ret}
";
}
?>
4.在浏览器里输入http://localhost/health/testphpjava.php
你会看到HelloWorld,这是java返回的字符串。

5.自己可以写一个新的类进行测试,但是一定要放在lajp下的java目录下,调用方式用lajp_call();,如果用到非常复杂的类,那么在php和java中一定要有对应的类,具体请参考网站文档。
