STEP1.8: Redirector Server -> Handler
To be able to work with VSAM data on another platform (ASCII), the most
important component is the Handler.
The handler is responsible for data manipulation and conversion. Therefore it
must know the structure (mapping) of the VSAM record.
The handler used in the workshop is the HtmlHandler.class
stored in directory: <redir>\com\ibm\vse\htmlhandler
The handler needs a map to split the record into fields. This map does not need
to be defined on the VSE system, but you can reuse a already defined map.
A map for a VSAM cluster can be defined with the Maptool, VSE Navigator or
IDCAMS RECMAP utility.
We work with the VSAM Cluster FLIGHT.ORDERING.ORDERS
The ORDERS_MAP is already defined.
In the used HTML handler <redir>com\ibm\vse\htmlhandler\HtmlHandler.java
the mapping is hard coded.
The Record Layout of the ORDERS Cluster is defined as follows:
Offset Length Type Key Field Name Description
----------------------------------------------------------
0 20 STRING no FIRST_NAME First Name
20 20 STRING no LAST_NAME Last Name
40 4 UNSIGNED no FLIGHT_NUMBER Flight Number
44 4 UNSIGNED no SEATS Seats
48 1 BINARY no NON_SMOKE Smoker 0=no
The Record length is 49 Bytes
The Record Layout is reflected in the Map ORDERS_MAP
