Interface PortletTagModelProvider

All Superinterfaces:

PortletService, TagModelControllerProvider

public interface PortletTagModelProvider
extends PortletService, TagModelControllerProvider

TagModelProvider for portlet scope, i. e. with portlet request / response.

 PortletServiceHome psh;
 javax.naming.Context ctx = new javax.naming.InitialContext();
 boolean serviceAvailable = false;
 
 try {
     psh = (PortletServiceHome) ctx.lookup(PortletTagModelProvider.JNDI_NAME);
     serviceAvailable = true;
 } catch(javax.naming.NameNotFoundException ex) {
     ... error handling ...
 }
 ...
 if (serviceAvailable) {
    PortletTagModelProvider provider = (PortletTagModelProvider) psh.getPortletService(PortletTagModelProvider.class);
          TagModel model = provider.getTagModel(aRequest, aResponse);
     ...
 }
 

Note: The lookup for this provider should be executed within the init method of a portlet and only the lookup for the TagModel itself should be performed on a per-request basis.

Since:

7.0.0
