Creating OpenEdge SOAP Web Services : Building Clients for OpenEdge SOAP Web services : Defining and passing Web service method parameters
 

Defining and passing Web service method parameters

Most parameters are defined and passed in SOAP messages as XML Schema data types. OpenEdge Web services expose ABL parameter data types as XML data types in the WSDL based on the "2001 XML Schema: Data types" (referred to as xsd in Table 18).
The following table lists the data type mappings for parameters between ABL and XML data types. Most of these parameters can also be passed as arrays.

TABLE (static temp-table)

DATASET (static ProDataSet)3

DATASET-HANDLE (dynamic ProDataSet)4

1 LONGCHAR and MEMPTR data types are designed to support very large "strings" of data. Use of these data types as parameters in Web services can result in a serious performance impact.

2 TABLE, TABLE-HANDLE, DATASET, and DATASET-HANDLE data types cannot be passed as arrays. For more information on passing arrays, see Array parameters.

3 TABLE, TABLE-HANDLE, DATASET, and DATASET-HANDLE data types cannot be passed as arrays. For more information on passing arrays, see Array parameters.

4 TABLE, TABLE-HANDLE, DATASET, and DATASET-HANDLE data types cannot be passed as arrays. For more information on passing arrays, see Array parameters.

Note: ABL object type (class or interface) parameters and ABL BUFFER parameters are not supported.
