The Flex, Spring and BlazeDS full stack – Part 2: Writing the to-do list server

Creating a WAR module

In this section we'll get started creating the back-end of the to-do list sample application. First, open a command line in the todolist directory that we created in Part 1 of the series and run the following command:

mvn archetype:create \
-DgroupId=org.epseelon.samples \
-DartifactId=todolist-web \
-DarchetypeArtifactId=maven-archetype-webapp 

The command above creates a new todolist submodule inside the root todolist module. Next, edit the POM of this newly created module to add the following dependencies:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring</artifactId>
  <version>2.5.2</version>
</dependency>
<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjrt</artifactId>
  <version>1.5.4</version>
</dependency>
<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjweaver</artifactId>
  <version>1.5.4</version>
</dependency>
<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate</artifactId>
  <version>3.2.6.ga</version>
</dependency>

The dependencies added above are required for Spring and Hibernate to work.

Last but not least, update the configuration of the Java compiler plug-in in this module so that we can use generics and annotations in our code. Add the following plug-in configuration to the project/build/plugins node:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <source>1.5</source>
    <target>1.5</target>
  </configuration>
</plugin>

At this point we've set up the module for the back-end, to prepare it for development. In the next section, we'll build the interface for the to-do list service using Java.
