| DESCRIPTION OF ENHANCEMENTS |
This build contains TCP/IP transport functionality that enable synchronous
The VISTALINK package contains two native request handlers. One handles
system type requests, like client heartbeats and close socket requests.
The other handler processes RPC requests.
Other packages can also supply handlers. For example, the VISTALINK
SECURITY (XOBS) supplies a handler used the process VistA security
related requests.
VISTALINK allows request formats to be in (a) XML and conform to a XML
communication 1) from non-M based systems to M based VistA servers and 2)
Schema, (b) a proprietary format (package must supply proprietary parser)
or 3) both a and b.
VISTALINK also supplies a Java/J2EE side component that allows developers
of Java applications to make these synchronous requests on the M server
and for M applications to make synchronous requests of Java/J2EE
application servers. The Java/J2EE side implements the J2EE Connector
Architecture v1.0 framework (JCA).
(Note: As of 7/2003, VISTALINK only supports Java to M communication.)
from M Vista servers to non-M systems (typically Java/J2EE based systems).
Finally, the VISTALINK contains a number of library calls available to
other packages for developing a request handler if needed. (Currently,
only VISTALINK SECURITY is allowed to use these calls.)
Build: 1.0.0.124
The communications are in the form of requests.
For request received by the M based system, the VISTALINK package
contains a Request Manager to manage these requests. Requests are
forwarded to the appropriate Request Handler.
