Question

Im trying to write a gadget inside a jira plugin and I’ve encountered some problems even with a very simple one. Currently I’m trying to get a response from a simple java class i wrote. Following code is located in my gadget.xml:

        Hello Gadget<br />

    #requireResource("com.atlassian.gadgets.publisher:ajs-gadgets")
    #requireResource("com.tngtech.gadgets.jira-complain-gadget-plugin:web-resources")

    #includeResources() 

    #oauth

    <script type="text/javascript">(function () {
var gadget = AJS.Gadget({
    baseUrl: "__ATLASSIAN_BASE_URL__",
    view: {
        onResizeAdjustHeight: true,
        enableReload: true,
        template: function(args) {

            var gadget = this;

            window.alert("1");

            gadget.getView().html(args.hello);

            window.alert("2");

        },
        args: [{
            key: "hello",
            ajaxOptions: function () {
                return {
                    url: "/rest/jira-rest/1.0/ComplainChart/HelloWorld"
                };
            }
        }]
    }
});
})();
    </script>

]]></Content>

The Java class i adress looks like this:

@Path("/ComplainChart")
@AnonymousAllowed
@Produces(MediaType.TEXT_HTML)
public class ComplainChart {

public ComplainChart() {
}

@GET
@Path("/HelloWorld")
@Produces(MediaType.TEXT_HTML)
public Response getVersionsForProject() {
    return Response.ok("Hello Java<br/>").build();
}
}

The URL is probably correct, the firebug output for the get Request looks like this:

throw 1; < don't be evil' >{"http://localhost:1990/jira/rest/jira-rest/1.0/complainChart/HelloWorld?cacheBuster=1308293636385":{"headers":{"set-cookie":["JSESSIONID=5652167D4DADE39719C4FED0C7174A03;Path=/","atlassian.xsrf.token=BV8N-OK2J-IQUQ-YNNK|b52c0f4b28944d7d11561aed079093f767448aca|lin; Path=/jira"]},"body":"Hello Java<br/>","rc":200}}

Even without the gadget.getView part, the alerts aren’t executed (they are without the args part) and I get a huge Stack Trace in my atlas-run terminal

[INFO] [talledLocalContainer] com.atlassian.util.concurrent.LazyReference$InitializationException: com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes.

Can anyone help me please?

Found the solution: You need to return an Object of an own class with annotations like these:

    @XmlRootElement
public static class HelloClass {
    @XmlElement
    String output;

    HelloClass() {
        output = "Hello";
    }

    HelloClass(String who) {
        output = "Hello " + who;
    }
}
