Write simple codes

Rule #1: codes should simple Struggling for fixing the bugs within the complex and repeatable codes in the projects. Codes should always be  simple and readable.  If you have to write complicated codes, refer to rule #1.

Lesson learned from current projects(ongoing)

Test is important( need to plan the test before you commit the codes in production) 4. Version control. Currently, the projects running on three places. The development, staging and production. The production running the stable codes retrieved from trunk, the staging always have the tested codes from development environment; development environment have the latest codes(some

Obtaining Spring Releases From Maven Central

You do not have to add a repository to your .pom to obtain  final  releases of Spring projects from Maven Central. Simply add the dependencies your project requires. A .pom <dependency> snippet for each Spring Framework 3 artifact as it will be indexed in Maven Central is listed below. <!-- Shared version number properties --> <properties>     <org.springframework.version>3.0.5.RELEASE</org.springframework.version> </properties> <!--     Core utilities used by other modules.     Define this if you use Spring Utility APIs (org.springframework.core.*/org.springframework.util.*) --> <dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-core</artifactId>   <version>${org.springframework.version}</version> </dependency> <!--     Expression Language (depends on spring-core)     Define this if you use Spring Expression APIs (org.springframework.expression
