If all goes well, your application will be shown in a few moments. (I assume your application is a Java Swing or JavaFX GUI app.) You can then type type open release to open the folder that contains your app, and then you can use the Mac Finder to copy your app to your desktop (or anywhere else). Note 1: Font smoothing. Netbeans can be installed and used on Mac, Windows, and Linux. The NetBeans IDE is primarily intended for development in Java but also supports other languages, in particular, PHP, C/Cand HTML5. Netbeans is a great fit when it comes to development with Java persistence API, JSP, spring, struts, servlets, web services and Hibernate frameworks.

1- Why is security used?
Security is an important aspect of an application with transport of important data on the Internet.
Authentication
Authentication is the process by which users' access privileges are verified prior to their entering a Website's protected area. There are two major authentication approaches: basic authentication and form-based authentication.
For basic authentication, a user can access every page completely normally. For the pages requesting security, a window will display for the user to enter his/her username/password. The username/password information will be bundled up to send with the request to Server.
When the user enters a path on browser, and press Enter to request a page. A ' User Agent' information is created and sent with the request. Normally, this information includes the user's browser information, operating system information. In case of basic authentication, the username/password information is bundled within the ' User Agent'.
In this post, I don't mention basic authentication in details.
Most websites use Form-based Authentication. A website allows the user to access every common page without asking for a password. However, if the user visits a protected page, it will redirect to a login page.
In this lesson, I will detail the usage of a Servlet Filter to keep secret Java Web application.
2- Concept of Role and Principal
In security, there are 2 important concepts such as Principal and Role.
Role is a set of permissions for an application.
For simplicity, I give an example, the ABC application has 2 roles of ' EMPLOYEE' and ' MANAGER'.
Principal can be temporarily understood as a 'Subject' after logging into a system. It is entitled to do something in the system. An 'Subject' can have one or more roles. This depends on the permissions of application for each different user account.
3- Security with Servlet Filter
In the Java Servlet application, a Servlet Filter is specially used to handle security. It is usually called Security Filter.
Below are the operation principles of the Security Filter.
When the user accesses a protected page, the Security Filter will test it. If the user is not logged in, the user's request will be redirected to the login page.
If the user has accessed successfully, a Principal object is created. It brings the user's information, including roles.
If the user has successfully logged in before, and accessed to a protected page. The Security Filter will check if the user's roles are appropriate to access this page or not. If it is invalid, it will show the user a page informing Access denied.
4- The goal of example
This is the structure of application which we will perform:
The application includes 2 roles such as EMPLOYEE and MANAGER.
5- Create Application
On Eclipse, create a 'Dynamic Web Project' called SecurityWebApp, and configure so that it can run on Tomcat Server. I will not detail the steps to do this, you can refer to the following lesson:
6- UserAccount & DataDAO
UserAccount class represents for the user of application.
DataDAO class is used to query data in Database (Simulation).
7- SecurityConfig & SecurityUtilsFree Java Download For Mac
Lớp SecurityConfig giúp cấu hình các vai trò và các chức năng (các trang) được phép truy cập ứng với vai trò đó.
SecurityUtils class is a utility class, which has methods to help check if a request is required to be logged in or not, and whether such request is suitable for the role of user logged or not.
8- SecurityFilter
SecurityFilter is a Servlet Filter, which does the duty of checking requests before allowing accessing the protected pages.
SecurityFilter reads 'security configurations' declared in the SecurityConfig class. 9- Home Page, Login, LogoutRun Application:10- Pages must be logged in![]() Run Application:
Run the application and log in with userName = 'employee1', which is user with the role of 'EMPLOYEE'.
![]()
Run the application and log in with userName = 'manager1', which is user with the 2 roles such as 'EMPLOYEE' and 'MANAGER'.

This documents instructs you on how to setup a Java programmingenvironment for your Mac OS X computer and provides a step-by-stepguide to creating, compiling, and executing a Java program.We assume you are running at least OS X 10.2.3.All of the software is freely available on the Web.
You will use the Java compiler javac to compile your Java programs andthe Java interpreter java to run them.Mac OS X includes implementation of Java 2 Standard Edition (J2SE) 1.4.1,so there is nothing to do in this step.
You will type commands in an application called the Terminal.You might enjoy reading Neal Stephenson's light-heartedessay In the Beginningwas the Command Line.
You will type and edit your programs in a text editor called JEdit.JEdit is similar to conventional word processors like MS Word,but it features many specialized programming tools includingsyntax highlighting, bracket matching, auto indenting, indentshifting, line numbering, and commenting out code.
