Hello Primoz,
Actually, the code you wrote should work. What JSP engine are you using?
Dani's code might do the trick. If that still doesn't work, you might want
to try using a Singleton (see the book Design Patterns by Gamma et al.) to
make sure that only one instance of the class is ever created.
regards,
Manne

Subject: Re: bean initialization lock
Hi, it should be working, shouldn't it?. Try putting your init()
reference into you bean constructor method.
Bye, Dani
