RE: Changing file permissions from within tomcat does not work
Hola, This is typical of when apps step outside the Servlet Spec, which does not include support for apps writing files except to a temporary directory where permissions are guaranteed to be readable back by the app and no more. Tomcat supports running with a security manager, but you have to tell it so explicitly by specifying -security when launching Tomcat. If you're doing this, you will need to modify your java security policy to include setting file permissions. But my guess is you're running without a security manager, which is OK and the default. So Runtime.exec should work. You will need to pass it the complete path to the file, as you cannot rely on the concept of current working directory to be portable. Runtime.exec is also a security risk in most environments.

Re: Changing file permissions from within tomcat does not work
And the directory's permissions are the same? (should be, but just in case) remember that new files don't necesarilly have rw-r--r-- permissions Christian Riedel escribió: On 19.08.2004 16:36, John Villar wrote: just as a gues have you sat the Sticky or the UID bit of your directory?

Runtime.exec is also a security risk in most environments. Thats what I thought ... and as you can see from my original posting I am passing the full path to chmod and the full path to the file when calling exec() ... The thing is: I can see that chmod itself seems to do something, but in a completely weird and unwanted way ... why should it work when I want to set the permission to 007 (which actually is working - even from within the application) But not, when I want to ste the permissions to 660 This seems totally unpredictable and unexplainable to me :-( Any more hints? But maybe I can try it with the security option tomorrow Christian -- To reply to this posting directly use the following address and remove the 'NO-SPAM' part: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
