JFacets : the profile based framework | WebFacets / WritingFacets

Writing web-enabled facets is strictly similar to write facets in regular Java applications. Of course, you can write your facets the Java or the Groovy way, or both !

One thing has to be noticed. With the extended web facet context, you can access the javax.serlvet.http.* objects from your facet code if needed.

From pure Java facets :

[Get Code]

/**
* A facet that does things with the request
*/
public class MyWebFacet implements IFacet {

/** web-enabled facet context */
private IWebFacetContext context;

/** from IFacet */
public IWebFacetContext getContext() {
return context;
}

/** from IFacet */
public void setContext(IFacetContext context) {
this.context = (IWebFacetContext)context;
}

public void doStuff() {
// get the request
HttpServletRequest request = getContext().getRequest();
request.setAttribute("myFacet", this);
String param = request.getParameter("param");
...

}

}

From Groovy Facets :

[Get Code]

/*
* Executable groovy script
*/
o = ... ;
context.request.setAttribute("something", o);
p = request.getParameter("param");
...
