Basic Data Types

  • Artikel

Microsoft BizTalk Adapter for JD Edwards OneWorld provides access only to JD Edwards OneWorld business functions. Business function metadata is read using a business function interface and used to find a list of business functions and associated data structures. Metadata is strongly typed in all cases for all business function methods.

All business function methods have the same calling convention: three parameters that are system derived, and a pointer to a data structure. The following table shows how the business function data types are represented.

Business function data types

JD Edwards OneWorld Data Type Description WDSL Conversion
char Character string. xsd:string of 1
int Short integer. xsd:short
long Long integer. xsd:short
String See Handling String Values. xsd:string
JDEDATE Special implementation of dates. xsd:date
MATH_NUMERIC Special implementation of floating point numbers, including currency values. xsd:string of 32
Byte Single unsigned character. xsd:string of 1

The following table contains the list of basic types in JD Edwards OneWorld and how they map to the Microsoft .NET Framework.

Note

If there is only one argument, and the return argument is void, the holder is replaced by the class, and the out portion becomes the return value. For example:

org.apache.axis.holders.DateHolder becomes a java.util.Date.

The following is an example of method signatures:

void testDate1(org.apache.axis.holders.DateHolder date1  
        org.apache.axis.holders.DateHolder date2);  
  
java.util.Date testDate2(java.util.Date date);

Character-Limited Strings

In JD Edwards OneWorld, some strings are character-limited. Any extra character causes an error. To see the limit of characters in the strings, you can use the Microsoft Adapter Wizard.
