Hide resources according user permissions

Hi i'm developening a struts application and i want to make my jsp according users permissions. For example i would like to hide a link to another jsp if the user doesn't have permission to see it.

Does anyone know a pattern or a tag lib to do this automatically? i'm looking for a better way than calling a method (something like isAuthorized() ) from a created object inside every jsp i have.
I also don't want every link in my jsp beeing inside an if statement.

Thanks in advance.

One possible solution might be to develop your own custom tag that encapsulates your authorization logic. Example:

I know you said you didn't want everything inside an if statement, but there has to be some conditional logic in there somewhere. At least with a custom tag it's more readable.

Merrill makes the correct suggestion. You could also use some existing libraries such as logic resent and logic:equals to accomplish the same thing if you're not keen on creating custom taglibs. Just a thought. However, the custom library is the right way to go if you have the time.
Hope this helps.

I agree. Here's the link:
