  1. Iris Application Server 1.0.1 Released (4 messages)

    Accendia is pleased to announce the release of Iris Application Server 1.0.1. The ideal use for Iris is to implement Java distributed applications where low memory footprint or communication performance are important. The implementation offers synchronous, asynchrounous and client callback communication models as well as integrated application security and communication security.

    An Iris hosted application is comprised of arbitrary Java objects called commands that are associated an external name. Clients connect to the server and invoke the application commands through proxies created at runtime. A client proxy
    implements all the interfaces implemented by the corresponding command object and delegates the invocation of any
    method in any interface to the remote server object.

    Asynchronous method invocation is implemented by declaring the return type of the method void. If the return
    type of a method is not void the call is synchronous.

    Client callbacks are implemented by declaring a set of callback interfaces. The client provides callback handler objects that implement these interfaces. The server obtains a client proxy that implements all the callback interfaces and invokes one of
    the interfaces. The invocation will be delegated to the callback handler registered on the client side for the corresponding callback interface.

    The client-server communication relies on an efficient binary protocol and a Java NIO based implementation. Iris is using a configurable number of worker threads to process the client requests and a few threads to process socket events.
    This means the server can handle thousands of simultaneously connected clients using a limited number of threads.

    The application security is implemented defining user roles and execution grants for these roles with application, command or interface granularity. After application deployment the administrator creates users and grants application roles to the users. The server loads the user roles at user login and performs execution privilege verifications on each invocations using only a few CPU cycles.

    To enable secure communication the administrator must install a SSL certificate on the server side. The client can then specify the secure flag when connecting.

    The JavaDoc for the (tiny) Iris API is available online as well as a tutorial that explains how we developed the datasynch sample application that is part of the distribution package. We believe the learning curve for Iris is small and we are waiting for your feedback.

  2. Cool entry but too late!!! There are already lot of matured app servers in the market targeting different segments. Another new app server does'nt make sense.

    But one cannot forget "There is always room at the top"

  3. This sounds very encouraging. I didn't expect the announcement to be "cool".

    There are some excellent products on the market but Iris is different than anything else.

    We are targeting Java projects that would otherwise design their custom wire protocol over TCP/IP sockets rather than using an existing solution.

    I made a search on Google for "There is always room at the top" and look what I found:
  4. Anyone used it ?[ Go to top ]

    Sounds interesting ...

    I would be interested in hearing from anyone who has used Iris in production, why they chose it over other remoting technology options and what the overall experience was (i.e. ease of development, performance, etc).

  5. Anyone used it ?[ Go to top ]

    We are looking for developers to review us. We initiated an Accendia Forum where users can get help. We are interested about their experience so far with the product.

    It's too early for the "Success Stories" webpage as we are only 2 months new.
