Mix protocols transparently in Web applications To maintain the security of sensitive data as it travels over the Internet to or from the browser, Web applications often rely on Secure Sockets Layer. The secure Webpages and processes that transmit sensitive data utilize HTTP over SSL (HTTPS) rather than the usual HTTP. Integrating SSL into a Web application should prove seamless and simple to implement as well as maintain. This article explores typical SSL implementations and develops an SSL solution using the J2EE servlet redirect mechanism to protect sensitive data transmission. It also develops an overall solution combining JavaServer Pages custom tags and an application-specific servlet base class. |

Customized EJB security in JBoss The current Enterprise JavaBeans specification supports basic declarative, role-based access-control mechanisms, but provides limited support for coding application-specific security checks. Moreover, it doesn't define any way to factor out access-control code from business logic, or to integrate external authorization services. The open source, J2EE-compliant JBoss application server features a protection-proxy security architecture that will help you overcome these restrictions. |

Implement Design by Contract for Java using dynamic proxies The Design by Contract (DBC) theory can dramatically raise software quality and reusability levels by forcing you to think in terms of contracts. Contracts formally specify the responsibility relationship between a client (class user) and a supplier (class). Additionally, DBC clearly separates specification (what) from implementation (how). This article explains DBC's importance in object-oriented development and describes a DBCProxy framework that achieves DBC transparently in Java using dynamic proxy classes. |
