Put your data into the session or use parameters with a result as described here and there.
Parameters can be passed to results using the params attribute. The value of this attribute is a string array with an even number of elements in the form {"key0", "value0, "key1", "value1" ... "keyN", "valueN"}. For example:
@Action(value="/different/url", results={@Result(name="success", type="httpheader", params={"status", "500", "errorMessage", "Internal Error"})} )
