Introduction to Spring LDAP
In this article Spring LDAP which provides a simplified wrapper framework around LDAP implementations is covered in detail. This article assumes that the reader has a basic understanding on Spring framework and LDAP directory server. The first section of the article covers the various operations that can be performed on LDAP. Support for parsing externally stored LDAP data is also covered with the help of LDIF data. The ODM Manager APIs for mapping LDAP objects directly to java objects have also been explored in this article. If you are beginner in learning spring framework, please read Introduction to Spring Framework.
Creating Database aware applications in Ruby on Rails
In this article, we will explore the capabilities of Ruby with respect to the Data Tier. One can understand the power of Ruby which greatly simplifies the development of data aware applications after reading this article. This is mainly because of the abstraction introduced in Ruby in the form of Active Record. Active Record defines the object relational mapping between Ruby objects and Database tables. The first section of this article will deal with Active Record and how to work with CRUD operations using it. The later section of the article guides in developing a full-blown web application using the Active Record API.
Managing transactions in EJB 3.0
Transaction represents a group of activities that must be performed as a single work unit. This clarifies that a transaction is complete if and only if all the work items within a work group results in success. If any of the work items fails, then the transaction as a whole will be treated as a failure. Managing transactions is vital not only for Enterprise applications but also for any flavour of applications. In this article we will explore the various services provided by the EJB container with respect to transaction management. This article assumes that the reader has a basic understanding on EJB technology such the various EJB containers, enterprise beans etc along with the fundamental concepts of transactions such as ACID properties, commit and rollback.
Creating RIA with Adobe Flex framework
Adobe Flex provides a platform for developing Rich Internet applications (RIA). Adobe Flex is not one thing but it is a combination of various languages, frameworks and builders like MXML, Action Script, SDK and Flex Builder. For creating Adobe Flex applications, we use the markup language MXML which is similar to XML in syntax. Action Script is the scripting language that provides dynamic capabilities. The Adobe Flex SD includes a rich set of APIs for building complex user applications and finally Flex Builder is an IDE based on Eclipse base platform that provides developmental support for building applications.
Securing EJB Applications
In this article, we will see the various aspects in securing an EJB Application. Security is vital not only for an enterprise application but also for any kind of application. It is essential to identify the system or the users accessing the applications and to provide access or denial for resources within the application based on some criteria. The point is that not every user should be given the rights to access sensible data and there must be some identification mechanism to distinguish this boundary. EJB specification for security falls in Declarative and Programmatic mode, the EJB Container owns the responsibility of establishing security for enterprise beans in the former mode whereas the application developer has to embed security specific code in the enterprise bean in the latter mode.
