Development Environment configuration document

1. technologies and tools involved:

+ Ant1.6.2 (project management)
+ Eclipse2.1.2 (code development tool)
+ Junit2.1.1 (Code Testing Tool)
+ Jdk1.4.2 (JVM)
+ Struts1.1 (Web-layer MVC)
+ Ejb2.0 (business layer logic)
+ Hibernate2.1.2 (entity layer)
+ Dao (separated display and logic layer)
+ Jboss3.2.5 (middleware)
+ Log4j1.2.8 (logging)
 
2. Environment configuration method:
 
A. Install jdk1.4.2 and ant1.6.2
Decompress the corresponding compressed package to the corresponding directory, usually use/usr/local/*. Set the corresponding environment variable.

B. Install eclipse2.1.2
Decompress the corresponding compressed package to the corresponding directory, usually using/opt /*.
[Note] eclipse integrates with JUnit

C. Install the Eclipse plug-in
Easystruts0.6.4 (struts supported)
Tanghan1.0 (support for hibernate)
Lomboz2.1.6 (supporting J2EE)
Specific configuration: http://www.bcxy.com/java/eclipsej2ee.htm

D. Install jboss3.2.5
Decompress the corresponding compressed package to the corresponding directory, usually using/usr/local /*.
Specific J2EE configuration: http://www.bcxy.com/server/tomcatjboss.htm
 
E. Configure log4j1.2.8
Specific configuration: http://www.bcxy.com/java/log.htm

 
3. Development Environment Design:

A. Develop the Directory design and write the Project Management Configuration File. (set the directory/opt/bcxy)
 
B. System architecture design.
Analyze the business logic, convert each business operation into a method in EJB, and then refine the EJB method to specific to each operation in Dao.
The entity layer uses hibernate to map to the database. Dao will encapsulate all database table operations.
Strtus is used to break down business processes and display related prompts and error messages.
Conclusion: The presentation layer, business logic layer, and entity layer should be separated as much as possible.
Specifically, the exception is handled, and the exception is encapsulated into the business layer.


4. Code development method:

A. Set the eclipse development project directory to the Project Development Directory (/opt/bcxy)
 
B. Learn how to use eclipse and related plug-ins.
