标题: java中调用python程序
费了一天的时间，想用Jpython生成的jar文件在java中调用，没有行能，既然行不通，那就反过来吧，在java中直接调用python程序，呵呵，成功了，现在拿出来与大家分享

Jpython jython2.2.1
JDK 1.5

以下是程序代码
python.java

import java.util.List;

import org.python.core.PyException;
import org.python.core.PyInteger;
import org.python.core.PyObject;
import org.python.util.PythonInterpreter;
public class python {
public static void main(String []args)throws PyException
{
PythonInterpreter interp =new PythonInterpreter();

System.out.println("Hello, brave new world"

;

interp.exec("import sys"

;
interp.exec("print sys"

;

interp.set("a", new PyInteger(42));
interp.exec("print 'test='+str(a)"

;
interp.exec("x = 2+2"

;
PyObject x = interp.get("x"

;

System.out.println("x: "+x);
System.out.println("Goodbye, cruel world"

;

interp.exec("import re"

;

interp.exec("t =re.compile('^(0{2})

IFCSUM)

MANIFEST):')"

;
interp.exec(" a = t.search('00:IFCSUM:MANIFEST:').groups()"

;
PyObject k = interp.get("a");
List list = ((List)k.__tojava__(List.class));

//System.out.println(k);
System.out.println(list);

}
}
