Lets say I'm doing some user input checking to prevent spam. Since I am using myxwiki.org service and have no access to the back end code I could have some hard coded sensitive info in my script (ie. u/p to twitter or facebook).

Will it show Groovy as well as Velocity code?

Blocking users from copying a script is tricky business. To start with, an exception will cause the content to be dumped in the error message. You might try this: create a page (I will call it Main.banned, but you can call it what you like.) This will contain your secret groovy script. put this in it public class MySecretClass{ public String go(){ //your code goes here, it can only output things through //the return statement, println and errors will not be shown. String out = "hello world!";//my test code :) return out; } } NOTE: there are no <% or {{groovy}} marks Set the permissions of this page so that only you are allowed to view it. create another page (which users are allowed to view.) in this page put: {{velocity}} #set($myclass = $xwiki.parseGroovyFromPage("Main.banned")) $myclass.go() {{/velocity}} now unregistered users and users without permission can view the page with the velocity code (which executes the groovy page), but not view the page with the groovy code (with viewer=code or otherwise.) In the event of an exception in your groovy code, the user will see a velocity exception, and the exact error (eg StringIndexOutOfBoundsException -1) will be shown, but not the groovy code. I have tested this and it works. A user without any special permissions can copy the velocity code and run it themselves, but I can't see any way for them to read the groovy code.

Thanks for the response (Caleb James DeLisle and Sergiu). I am using myxwiki.org so not sure if I have access to .vm files?! I think a way of disabling viewer=code should be available ASAP. As it is not obvious (especially for new xwiki users/developers) that any code is publicly acessible and there is no clear way of hiding Groovy + Velocity code from the public (or search engines) this "feature" poses a great security risk. Someone unaware of this feature (like I was) and using a 3rd party API which requires authentication could easily embed and revile username/password to the whole world.
