HeaderPortletinterface. The annotated method must have one of the following signatures:
public void <methodName>(HeaderRequest, HeaderResponse)
This corresponds to the
public String <methodName>()
The String returned by the method will be made available to the portal for inclusion in the document head section.
public void <methodName>()
The method declaration may contain a throws clause. Exceptions declared in the
throws clause should be of type
Checked exceptions of any other type will be caught, wrapped with a PortletException,
The header method can be used to set properties such as cookies, header values, and
XML elements for the

The annotated method can apply to multiple portlets within the portlet application. The names of the portlets to which the resources apply must be specified in this field.
A wildcard character '*' can be specified in the first portletName array element to indicate that the resource declarations are to apply to all portlets in the portlet application. If specified, the wildcard character must appear alone in the first array element.
public abstract String portletMode
If an portlet mode is specified, the bean enabler will dispatch Header requests with matching portlet mode values to this method.
If this field is empty, the method will be executed for all Header requests not dispatched by portlet mode to other HeaderMethods.
public abstract String contentType
If this field is empty or set to the wildcard, no content type will be set.
The portlet can then set the content type using the portlet API
public abstract String include
