Subject: [grouper-users] need help fo hooks

 

Hello,

 

I'm on grouper 2.2.2. I want to write a hook that put an uuid on created groups. The value of the uuid is stored in a table in grouper.

 

I'm not good on java coding, I've written the code inspired by "Getting started with hooks2" and the "LDAPProvisioningHook" code.

 

I'm getting errors of course and it is not compiled. (I compile using ant from the api binary).

 

Thank you everyone for any help.
