Re: [INTERFACES] Servlets and JDBC driver: Access Exception

I don't think the application (Main) class would change anything as you're
not running into, say, the applet sandbox, and the servlet engine is
effectively an application itself.

Try

i) Using a permissions file (under Java 2) e.g.

grant {
// Allow everything for now * MUST BE CHANGED FOR PRODUCTION
permission java.security.AllPermission;
};

*and* this to the JVM:

-Djava.security.policy=D:\<dir>\somename.policy

ii) Check the pg_hba.conf file in the Postgres data directory. This
specifies which hosts are allowed to connect to the database.

iii) Check the password :) !
