Web Deployment for Java Swing Clients
|
JNetStart 2.2
JNetStart facilitates launching Java Swing applications deployed on a remote server
without installing or downloading the application component files. The technology narrows
the gap between the web browser and Swing by making large client applications
instantly available to the user and providing a web style experience in the startup process.
Key Facts
- JNetStart is comprised of a server where Swing applications are deployed
and a client stub that loads the application classes and resources on demand;
- The application code is downloaded from the server and runs on the client computer;
- An API is provided that allows the client to invoke Java objects deployed on the server over
the same socket connection used for downloading the code. This feature limits the number of sockets opened
for each client to one reducing initialization time and keeping the number of sockets opened on the server to
minimum;
- The application runs in a secure environment similar to Java Applets and unsigned applications
in WebStart. A secure API is provided for developing applications that read and write local files
and print documents under strict user control.

Iris Application Server 2.2
Iris is a complete solution for developing Java client/server applications.
The technology provides a binary communication protocol that facilitates
the invocation of objects deployed on the server or client,
integrated application security through access
control lists and communication security based on public key infrastructure
and Java standards cryptography.
Key Facts
- Iris implements client/server communication through remote procedure call;
the method invoked and parameters are serialized and deserialized by client side
proxies and server skeletons generated automatically at server startup;
- Synchronous, asynchronous and client callback invocations are performed over
the same socket connection;
- The server memory footprint is minimal (<15Mb);
- The server uses Java NIO selectors to process connection events and a fixed number
of worker threads to service client requests;
- The application developer defines application roles and asigns roles to server users;
privileges verification is performed by the server on every remote invocation using
only a few CPU cycles;
- Communication security is enabled installing a CA certificate on the server.
