Hi Petri,
To generate a DirectLink href programmatically, you'll need a class
that implements IDirect. In the trigger() method on that, you can call
the intended listener. Refer to an instance of the class implementing
IDirect for the first parameter of DirectServiceParameter, set the
Direct engine service on it (@InjectObject("engine-service:direct") or
with a setter for a regular service), and create the href portion like
this:
public String getDirectHref()
{
Object[] params = new Object[] { param1, param2, etc };
DirectServiceParameter dsParam = new DirectServiceParameter(this, params);
ILink link = directService.getLink(false, dsParam);
return link.getURL();
}
