PythonScripts only allow a set of functions to be executed. Check the Scripting chapter of the Zope Book or the README in lib/python/Products/PythonScripts. -aj ----- Original Message ----- From: dannis To: zope@zope.org Sent: Tuesday, May 28, 2002 11:24 Subject: [Zope] permission to do execv() hi all: I'm a newbie to Zope. As my DTML doc called python script , a permission problem occured. I was prompted to key in username/passwd, but I had no idea which account I shall use. I used the function os.execv() in my script , but the function failed to execute because I was unauthorized. The following is the error message: Zope Error Zope has encountered an error while publishing this resource. Error Type: Unauthorized Error Value: You are not allowed to access execv in this context How can I get rid of this problem? Any suggestion would be appreciate ：）
