Create a module portlet controller

Module portlet controllers, along with form controllers, are typically put in the omod/src/main/java/web.controller folder and have names ending with PortletController.  Portlet controllers should extend PortletController. If there are actions that need to be taken when the portlet is referenced, override the populateModel method.  Any property added to the model in the populateModule method is available UNDER the "model" property.  So if you add "myvar" to the model object, in your portlet jsp you access it with ${model.myvar}.  Here is an example:

Code Block
@Controller
@RequestMapping("**/this.portlet")
public class ThisPortletController extends PortletController {
    
    private static final Log log = LogFactory.getLog(ThisPortletController.class);
    @SuppressWarnings("unchecked")
    @Override
    protected void populateModel(HttpServletRequest request, Map<String, Object> model) {
// your code here
    }
}

Make sure the following line exists in your ModuleApplicationContext.xml file, substituting your module name for ModuleID.  It typically is put just above the </beans> tag at the end.

Code Block
    <context:component-scan base-package="org.openmrs.module.ModuleID" />

Create the module portlet jsp

Module portlets are defined in the omod/src/main/webapp/portlets folder.  In our example, the portlet would be named this.jsp.  The code inside of a portlet shouldn't have to differ from a standard OpenMRS portlet, meaning that it looks exactly like a jsp (or part of a jsp).

Use the portlet in another jsp page

Portlets are included in a jsp by using the following tag:

Code Block
<openmrs:portlet url="this.portlet" id="thisportlet" moduleId="ModuleID" />

Note that you must specify moduleId="...", which differs from using a portlet in core code.
