使用Python中的“subprocess”调用Java应用程序并阅读Java app输出

Question

What is the nicest way to read the output (ie via System.out.println) of a Java app which is called from Python with

subprocess.Popen("java MyClass", shell=True)

without writing and reading a file? (Using Jython etc is not a possible solution)

Answer 1

p1 = subprocess.Popen(["/usr/bin/java", "MyClass"], stdout=subprocess.PIPE)
print p1.stdout.read() 

Answer 2

I just found the solution:

p = subprocess.Popen("java MyClass",
          shell=True,
          stdout=subprocess.PIPE)
output, errors = p.communicate()

S.Mark's is fine too!
