Hi, if you use Java EE 6 container managed security, you can configure security constraints for resources inside the web.xml deployment descriptor. Are there alternative ways to do this? For example the container could fetch them out of a database, like it does with the user data. Is something like this possible? I would like a way th...
Hello, When I include a 'disabled' attribute on an a4j:commandButton, the button's action is not performed. Taking the 'disabled' attribute out causes it to work properly.

I'm following the Java EE firstcup tutorial using Netbeans and Glassfish. When I execute the JSF web tier I've been instructed to code, the browser gets the same JSF markup coded in the .xhtml file, and the tags are not rendered as HTML tags.

For instance, application A has entities for Table1, Table2, etc; at the same time, application B also has entities for Table1, Table2, etc. Instead of that I want to create a new EJB module with 1 b...

I have basic spring security set up in my Spring / Java EE web app. I can restrict access to certain pages and force login (with roles etc.).

I want to manage user and roles in a dedicated application. For example a user of this application ("customerX boss") can create a new role "customerX employee".

I have a web app where I load components lazily. There is a lot of static Bla bla; ... if(bla == null) bla = new Bla(); spread throughout the code.

I'm writing a very simple web framework using Java servlets for learning purposes. I've done this before in PHP, and it worked by consulting the request URI, then instantiating the appropriate class and method. This worked fine in PHP, as one can do something like $c = new $x; $x->$y;. I'm unsure however of how to translate this to Java...
