Access to services is provided through Dependency Injection (DI); instead of the Java-backed web script locating its dependent services, the dependent services are handed to the web script.
SkyVault Content Services uses the Spring Framework for its Dependency Injection capabilities. This means that dependencies are specified in a separate XML configuration file as part of the Java-backed web script registration. For each dependency, the Java-backed web script provides a setter method for accepting a reference to the dependent service. The Spring Framework invokes each of the setter methods with the appropriate configured dependency during the initialization of the Java-backed web script. By the time the web script is executed, all dependent services are available within the executeImpl() method.
Your Folder Listing web script must locate the folder within the repository, identified by the folderpath token. To accomplish this, the web script injects a Repository service that provides some simple content repository access capabilities.

public class JavaDir extends DeclarativeWebScript
{
private Repository repository;
public void setRepository(Repository repository)
{
this.repository = repository;
}
protected Map<String, Object> executeImpl(WebScriptRequest req,
Status status, Cache cache)
{
...
if (folderPath.equals("Company Home")){
folder = repository.getCompanyHome();
}
else {
String nodePath = "workspace/SpacesStore/" + folderPath;
folder = repository.findNodeRef("path", nodePath.split("/"));
} ...
}
