i am running with jdl 1.5.12. New information about this issue: When i declare a simple method like this: | | public String echo(String name) { | return "Hello " + name; | } | I get proper response. Only when my methods have complex beans like this: | public String echo(UserData date) { | return "Hello " + data.getName(); | } | | @XmlAccessorType(XmlAccessType.FIELD) | UserData { | | @XmlElement(name = "name", required = true) | String name; | | public String getName() { | return name; | } | | public setName(String name) { | this.name = name; | } | | } | I am getting that exception in all these complex beans cases.
