[Jython-dev] jython servlet print >>out TypeError on Linux

[Brian Z. <bri...@ya...>]

Hi jython developers:

The following jython servlet runs fine on WinNT/2000, but gives me error
message (at the end of this message) when on Mandrake 7.2 Linux. Of
course no big deal, I can just use out.println("ABC") instead. Just
curious why.

import java, javax
class test(javax.servlet.http.HttpServlet):
    def doGet(self, request, response):
        out = response.getOutputStream()
        response.setContentType("text/plain")
        print >>out, "ABC"
        return
