This article is only a brief introduction
With more and more programmers use Enterprise JavaBean (EJB) components in their projects, the demand for simplified EJB development is also growing. This article will introduce several developed EJB tools. You can refer to its own characteristics, combined with its own development environment. This article is comparable to WebSphere V5.0 DB2.
The popular EJB Development Tool (IDE) and a combination have the following:
1. Eclipse 2.1 Lomboz 2.1 (free)
2. Eclipse 2.1 Ant 1.51 xdoclet1.2.0b2 orion1.60beta (free)
3. JBuilder9.0 (charge)
4. WSAD 5.0 (charged)
Eclipse 2.1 Lomboz 2.1
Eclipse - a good Java integrated development environment, I believe that many people are already in use.
Lomboz - a nice Eclipse plugin, the highest version is 2.1, free open source, development company / organization
Is http://www.objectlearn.com/ It will open a lot of Java application servers, J2EE components, and web applications
Send an integrated into Eclipse to help Java developers build, test, and deploy J2EE applications using Eclipse.
Support JSP syntax highlights, and Code Assist functionality can be compared with JBuilder.
Overall introduction: Eclipse Lomboz can be said to be a very nice combination, current Lomboz 2.1 version
Support EJB2.0 It can automatically generate EJB code and related deployments, which can be perfectly combined with JBoss and WebLogic.
But there is a certain difficulty in combination with WebSphere, because Lomboz is not supported by default, there is no WebShpere, you need to modify
Plug-in parameters, large difficult coefficients, and have enough understanding of WebSphere, including his running mechanism, etc.
Developing EJB advantages: Supporting development EJB can automatically generate code, open source free, fast.
Developing EJB Disadvantages: Generating EJB code is not standardized, joining a little own feature, and is difficult to combine IBM products.
ECILPSE 2.1.60b2 orion1.60beta
Eclipse - a good Java integrated development environment, I believe that many people are already in use.
Ant - Nice Builder tool, similar to the Make tool under Linux, perform various tasks in a batch form (such as file copy, compile, packaging, etc., and custom tasks). Development company or organization is http://www.apache.org.
XDoclet - xdoclets have developed from the EJBDoclet tool created by Rickard Oberg, which is easy to express: avoid providing multiple files for each EJB, but all information needed from a single bean class file. It is mainly used in EJB rapid development with Ant tools. Insert some specific Javadoc tags in your bean implementation, resolve, to generate various files, such as interface files and deployment description files. The concepts of many design patterns are introduced in version 1.2.0, such as automatically generating DAO and ValueObject objects, SessionFacade objects, and some tool classes. Development company or organization can view http://xdoclet.sourceforge.net/
Orion - Small appserver, but the function is very strong, it is gradually supporting EJB2.0. Development company or organization is www.orionsociety.com for information on IBM WebSphere application servers.
Overall introduction: ECILPSE 2.1 Ant 1.51 xdoclet1.2.0b2 Orion 2.0 Why is the combination of developments, first they are free, and almost all open source. Second, their combination is powerful, and the requirements for developers are low. Supports CMP / CMR, JSP, and JMS in EJB2.0. Whether it is C / S application or B / S app, it can quickly build a test platform. Obviously, this tool combination can be greatly developed.
Development EJB Advantages: The latest version of Orion 2.0 has begun to support EJB2.0, and free open source.
Development EJB Disadvantages: Configure trouble, difficulty.
