How to make a simple getter via AIF in AX 2012?

Question

I have a simple getter Class in AX and would like to use it via an AIF webservice from an external program. The Class looks like this:

static Email getEMail(HcmWorkerRecId _hcmWorkerRecId)
{
    ;
    email = HcmWorker::find(_hcmWorkerRecId).Email();
    return email;
}

What do I need to get an AIF Webservice out of it?

Answer 1

I just needed to add SysEntryPointAttribute Metadata attribute and set the method to public:

[SysEntryPointAttribute]
public Email getEMailByItemValueId(HcmWorkerRecId _hcmWorkerRecId)
{
    ;
    email = HcmWorker::find(_hcmWorkerRecId).Email();
    return email;
}

Then I added an service and an service group and deployed it.
