[Hibernate] Problems with hibernate.jar on a shared webapp

[Renato <rew...@ya...>]

Hi,

I'd like to report a problem regarding a shared webapp environment ( on Tomcat 4.1.x ). Since we do not allow users to change the System.properties environment, when somebody puts hibernate.jar on a webapp we got a security constraint violation:

Is it really necessary to modify the System.Properties ? If it is, is there any workaround to this problem, so somebody could use hibernate on a shared environment ?

Thanks for your time

Renato.
