Data mapping

Before coding a custom BP Server adapter, review the dataslots mapping to Java data types. The following data types are defined in Business Process Server: CHARACTER, INTEGER (containing Double, and Decimal), INT64, LOGICAL, DATETIME-TZ, LIST, Map, Object, and Business Object. The LOGICAL, INT64, INTEGER, and CHARACTER have one-to-one mapping to Java data types, as listed in the following table:

Table 10. Business Process Server dataslots to java data types mapping
Business Process Server dataslot type	Java data type	Notes
LOGICAL	com.progress.lang.Logical	None
DATE, DATETIME, DATETIME-TZ	com.progress.lang.DateTimeTZ	None
Document	java.lang.String	The Document dataslot, however, is actually a URL pointing to a document which resides on the Web server. Do not keep a document on the workflow engine, especially when it is large (as it becomes inefficient). However, only this URL is necessary to retrieve the actual document from the Web server.
LIST	java.util.Vector	None
Map	java.util.LinkedHashMap	None
DECIMAL	com.progress.lang.Decimal	None
INTEGER	com.progress.lang.Integer	None
INT64	com.progress.lang.Int64	None
Object	java.lang.Object	Your set() method must assign the object to the proper java class type. BP Server assigns the object, retrieved in the get() method to java.lang.Object.An example of how to use the Object dataslot is provided in the following section.
CHARACTER	com.progress.lang.Character	None
