Chapter 7 Selecting an EAServer Component for Your Web Service

Supported datatypes

This section describes the datatypes supported in Web Services Toolkit. The datatype must belong to a supported component type for it to be available as a Web Service. Supported datatypes include:

Java with IDL datatypes - the component's method declarations use the datatype mappings that are specified by the CORBA document, IDL to Java Language Mapping Specification (formal/99-07-53).
CORBA C++ with IDL datatypes - The component's method declarations use the OMG standard for translating CORBA IDL to C++, more specifically, refer to C++ Language Mapping Specification (formal/99-07-41). You can download this document from the OMG Web site . C++ datatype mappings are the same as Java/IDL component datatype mappings that are listed in Table 7-1.

Datatype mappings

The following table lists the datatypes displayed in Jaguar Manager and supported in Web Services Toolkit, the Java datatypes used in Java/IDL component methods, and the equivalent CORBA IDL types. CORBA C++ use the same mappings as Java/IDL component datatype mappings.

Table 7-1: Jaguar Manager, Java datatype equivalence, and CORBA IDL
Java primitive datatypes	java.lang object datatypes	org.omg CORBA holder datatypes
boolean	java.lang.Boolean	org.omg.CORBA.BooleanHolder
byte	java.lang.Byte	org.omg.CORBA.ByteHolder
double	java.lang.Double	org.omg.CORBA.DoubleHolder
float	java.lang.Float	org.omg.CORBA.FloatHolder
int	java.lang.Integer	org.omg.CORBA.IntHolder
long	java.lang.Long	org.omg.CORBA.LongHolder
short	java.lang.Short	org.omg.CORBA.ShortHolder
string	java.lang.String	org.omg.CORBA.StringHolder

The supported EAServer datatypes are:

BCD.BinaryHolder
BCD.Decimal
BCD.DecimalHolder
BCD.Money
BCD.MoneyHolder
MJD.Date
MJD.Time
MJD.Timestamp

Additionally, Web Services Toolkit supports:

Arrays of known datatypes, encoded as SOAP arrays by datatype, including support of arrays of arrays of any depth, but not including user-defined arrays.
java.util.Vector, encoded as ur-type arrays. Elements must be of a known datatype.
JavaBeans are not automatically supported. You have to perform datatype registration for them to work. See the "BeanSerializer class" for more information.
