  Get the primary key field specified for a given class. This is given by the `primkey-field` parameter on the `ejb.bean` tag, although this may be inherited from a superclass.

  Parameters:
    `clazz` - The class to look into
  Returns:
    The value of the ejb.bean primkey-field parameter
  Throws:
    `XDocletException`

### isMethodPrimkeyField

    public static boolean isMethodPrimkeyField(xjavadoc.XClass clazz,

  Parameters:
    `clazz` - The class to look into
    `method` - The method to check for primkey-field
  Returns:
    true if the method is a getter or setter for the primkey-field
  Throws:
    `XDocletException`
  See Also:
    `getPrimkeyFieldFor(XClass)`

  Parameters:
    `clazz` - The class to look into
  Returns:
    The name of the ejb.bean primkey-field parameter's getter method, or null if there isn't one
