I simply want to develop a portlet with a JSON service using Liferay IDE (Eclips Helios) and the Liferay Plugins SDK. See source below. I run "build servies" in Liferay IDE (Build Successful). Calling a page containing the portlet returns a NullPointerException (via JavaScript alert from view.jsp). What is wrong here?
service.xml:<!--?xml version="1.0"?-->
<service-builder package-path="de.company.liferay.portlet.test">
<namespace>TestNamespace</namespace>
<entity name="Test" local-service="true" remote-service="true" />
</service-builder>
view.jsp<script src="/test-portlet/js/service.js" language="JavaScript"> </script>
<script src="http://localhost:8080/html/js/jquery/jquery.js" language="JavaScript"> </script>
<script language="javascript">
function invokeService() {
Liferay.Service.TestNamespace.Test.test(
{
msg: "Invoking a Liferay service via JavaScript",
},
function(message) {
var exception = message.exception;
if (!exception) {
alert("No Exception");
}
else {
alert(exception);
}
}
);
}
invokeService();
</script>
TestServiceBaseImpl.java:package de.company.liferay.portlet.test.service.impl;
public class TestServiceImpl extends TestServiceBaseImpl {
public String test(String message) {
System.out.println("### REMOTE SERVICE CALLED: " + message);
return "success";
}
}
