How to get the hardware's product number via web service SDK?

Hi All,

    I need to get the host's serial/product numbers. I can get the serial number through,

    HostSystem: hardware.systemInfo.otherIdentifyInfo[].otherIdentifyInfo.identifierValue

    But it seemed like the product number is not anywhere from hardware's systeminfo.

    My question is: can the web service SDK API for java return the host's product number?

    Thanks in advance,

    Mike J.
