Hi Dave,
Not really sure why the bean validation stuff doesn't work but in order to
bind form params you probably need to configure your resource method and
binding class in a different way. Try the following:
@GET
public <my object class, not important>
resourceMethod(@Valid @*BeanParam* MyParams params)
{
...
}
public class MyParams {
@FormParam("a")
private ArrayList<String> stringList = new ArrayList<>();
...
}
This should bind your form params into your MyParams class.
A minor side note: The convention many frameworks use when binding http
params at method level is the POJO one (i.e. *set*This()/*get*This() rather
than addThis() etc)
HTF,
Savvas
