Open Admin is an open source framework for building administration programs based on GWT. The framework provides the ability to easily integrate Spring Security, SmartGWT, and JPA. Open Admin is a component of the Broadleaf Commerce framework and will be released to the open source community as part of BroadleafComerce version 1.5.

14. www.credera.com Simple Example - Step 1 of 3: Building The View public class SimpleView extends HLayoutimplements Instantiable, Display { public SimpleView() { setHeight100(); setWidth100(); } public void build(DataSource entityDataSource) { new IButton("Click Me"); button.addClickHandler(new ClickHandler() { public void onClick(ClickEvent event) { SC.say("Hello, World from smartGWT"); } }); addMember(button); }
15. www.credera.com Simple Example - Step 2 of 3: Creating the Open Admin Module public class SimpleModule extends AbstractModule { public void onModuleLoad() { setModuleTitle("Tech Fest Module"); List<String> roles= new ArrayList<String>(); roles.add("ROLE_TECH_FEST_USER”); roles.add("ROLE_ADMIN"); setSection("Simple Example”, "viewKey”, SimpleView.class.getName(), roles); registerModule(); } }
16. www.credera.com Simple Example - Step 3: Configuring the GWT Complier <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE module PUBLIC "-//Google Inc. <...> <module> <inherits name="com.google.gwt.user.User" /> <inherits name="org.broadleafcommerce.openadmin.openadmin" /> <entry-point class="techfest.client.simple.SimpleModule" /> <source path="client" /> </module> Also need to add reference to the project *.gwt.xml file.
18. www.credera.com Dynamic Form Generation The list grids and entry forms are generated automatically from the JPA and OpenAdmin configuration. @Column(name = "MODEL”) // JPA @AdminPresentation // Open Admin (friendlyName="Product Model", order=4, group="Product Description", prominent=true) Open Admin field configuration can be done via an XML file or inline in the java class. Other attributes include: readOnly, securityLevel, and validation
20. www.credera.com Recap the Steps for Adding a JPA Data Driven Section Create the view by extend BasicListDetailView Setting the title fields Set the view handle (prefix) Create the presenter by extending DynamicEntityPresenter Specify the grid fields (optional) Tie-in the associated DataSourceFactory Create the DataSourceFactory by extending SimpleDataSourceFactory Set the class name for your JPA configured class Add a new section to your module that references the view and presenter.
