1. Creating a JavaBean to Connect with Google API

By: Bruce W. Perry : 2008-11-24

Description: The first thing to do is get set up with a Google Web Services account. Now create a JavaBean that will make keyword searches of Google and return the results.

2. Spring Vs EJB ( A feature comparison)

By: Emiley J. : 2008-08-15

Description: In quite a few design brainstorming sessions, the debate between Spring and EJB results in a deadlock. There are developers who are damn passionate about Spring and hate EJBs. Let's have a look at the main important differences between the two in terms of features they support.

3. What is EJB server and what are EJB Components?

By: Emiley J. : 2008-08-13

Description: An EJB server is a high-level process or application that provides a run-time environment to support the execution of server applications that use enterprise beans. An EJB server provides a JNDI-accessible naming service, manages and coordinates the allocation of resources to client applications, provides access to system resources, and provides a transaction service. An EJB server could be provided by, for example, a database or application server.

4. JavaBeans Basic Concepts

By: Grenfel : 2007-10-12

Description: The JavaBeansâ„¢ architecture is based on a component model which enables developers to create software units called components. Components are self-contained, reusable software units that can be visually assembled into composite components, applets, applications, and servlets using visual application builder tools. JavaBean components are known as beans.

5. JavaBeans vs. Custom Tags

By: Emiley J : 2007-10-06

Description: It is necessary to know when to use tags as opposed to JavaBeans for wrapping up reusable functionality. After all, JavaBeans are reusable components and the JSP specification provides a built-in mechanism for integrating and utilizing the features provided by JavaBeans. Although both technologies can be used to achieve the same goal, that of encapsulating and abstracting data away from the JSP page, there are significant differences between the two.

6. Java Beans and the Expression Language

By: Henry : 2007-09-23

Description: EL in itself is not very useful when creating web applications. In this tutorial, you'll focus on how to use the EL to read values from JavaBeans to display within a JSP page. In previous incarnations of the JSP specification, you would have had to use code such as the following to read values from a JavaBean:

7. A sample that shows Java Beans, Servlets and JSP working together

By: Ivan Lim : 2007-09-23

Description: This tutorial shows the use of Java Beans, JSP and Servlet and how they work together. As an added bonus this tutorial also explains the use of nested properties of Java Beans using EL. The EL provides you with a simple mechanism to access nested properties of a JavaBean. For example, Listing below shows a JavaBean, which has a nested property of type Address

8. Advantages of Java Beans

By: Priya : 2007-09-15

Description: A Java Bean is a software component that has been designed to be reusable in a variety of different environments. There is no restriction on the capability of a Bean. It may perform a simple function, such as checking the spelling of a document, or a complex function, such as forecasting the performance of a stock portfolio. A Bean may be visible to an end user. One example of this is a button on a graphical user interface. A Bean may also be invisible to a user. Software to decode a stream of multimedia information in real time is an example of this type of building block. Finally, a Bean may be designed to work autonomously on a user's workstation or to work in cooperation with a set of other distributed components. Software to generate a pie chart from a set of data points is an example of a Bean that can execute locally. However, a Bean that provides real-time price information from a stock or commodities exchange would need to work in cooperation with other distributed software to obtain its data.

9. Design Patterns for Properties in a Java Bean

By: Sam Chen : 2007-09-15

Description: A property is a subset of a Bean's state. The values assigned to the properties determine the behavior and appearance of that component. This section discusses three types of properties: simple, Boolean, and indexed.

10. PKIX path building failed: unable to find valid certification path to requested target

By: Ramlak : 2007-07-12

Description: Are you getting this error? PKIX path building failed: unable to find valid certification path to requested target. This simply means that the web server or the URL you are connecting to does not have a valid certificate from an authorized CA. But however, being a programmer you would want to find out the alternative way to solve this issue.
