| DESCRIPTION OF ENHANCEMENTS |
This build contains TCP/IP transport functionality that enables
Handler.
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, VISTALINK SECURITY
(XOBS) supplies a handler that is used to process VistA security-related
requests.
synchronous communication from the following:
VISTALINK allows the following request formats:
1) XML and conform to a XML Schema
2) a proprietary format (package must supply a proprietary parser)
3) both 1 and 2
VISTALINK also supplies a Java/J2EE component that allows developers of
Java applications to make 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 (J2CA).
1) from non-M based systems to M-based VistA servers
** NOTE: VISTALINK v1.5 only supports Java to M communication.
Finally, 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: 1.5.0.026]
2) from M VistA servers to non-M systems (typically Java/J2EE based
systems)
The communications are in the form of requests. For requests received by
the M-based system, the VISTALINK package contains a Request Manager to
manage these requests. Requests are forwarded to the appropriate Request
