Browsing Metadata and Generating Schemas
This section explains how to use iWay Explorer to expose
and browse the objects within an EIS, and to generate schema for
those objects. iWay Explorer can connect to a variety of application
systems, each with their own information components, such as business
objects, database tables, or functions. See the adapter specific
user's guide for details on the components related to your adapter.

the object node of interest, and select Generate Schema from
the drop-down list. The following image shows an example of the
drop-down list.
The applicable schema
icons appear below the selected object. In the example shown in
the following image, the icons are for event, eventreply, request,
and response schema.
-
Select
the schema icon to view the schema in the right pane.

To save
the schema, right-click the schema and select either Save
As, Publish, or FTP Export from
the drop-down list. The following image shows this drop-down list
for the GetList request schema.
The following image

After
you generate the schemas, you can create an iWay Business Service
for the object you want to use with an adapter.
