    Any Suggestion to this


    MY company is looking to Re-engineer current client server application (Powerbuilder
    & Ms-SQLSERVER 7.0) to web based application. We are looking into EA-SERVER
    (Jagur & Power Dynamo) any suggestion regarding that or we should look into
    some think else. My company told me to do some research on it and to provide
    best solution for it. Thanks in advance.

    Liders on the market of app. servers:

    1. BEA
    2. Websphere
    3. Others [I-planet, Oracle, MS MTS, etc]

    If you go to web based, you need to consider going full java on development.

    Have a look at the WWW.techmetrix.com web site there are interesting studies
    and benchmarks on the subject

    Hi

    AS u said u above you can go for Power Dynamo and Jagur.If there is any Application
    Developed already with Power Dynamo or Jagur but as i understnd u r going
    new to web app so you can go for J2EE App Servers like iPlanet,WebShpere,Weblogic....they
    ahve good porablitiy.

    We also had the same problem and in case if you are planning ot use the existing
    business logic from the PowetBuilder Application, you have no other choice
    than EA Server. This will work only if you have used NVOs for the business
    logic. If you don't plan to re-write your applciation, then stay with Sybase
    tools as they will support it all the way or till PowerBuilder is alive.

    www.techmatrix.com is a good site to get the info on the various options
    but in the end with PowerBuilder objects, you really have no option other
    than either to use Jaguar CTS and Power Dynamo or re-write the application.

    You can also keep in touch with me on email rajeshranjan@consultant.com and
    we can discuss the various related issues....

    Ranjan is correct. Your options are limited if you do not plan on reengineering
    the entire application, but there is really no need. Besides, a complete
    overhall could cost millions. Most everyone seems to think JAVA is the silver-bullet,
    especially those that have no experience with anything else. As always, if
    there is not a multi-platform issue, Web.PB and the PowerBuilder browser
    plugins should do the job. If you don't have a middle-tier, you will have
    to build one. There is an excellent book which could assist you. It is in
    the Powerbuilder Developers Library series. The title is 'Internet and Intranet
    Applications with Powerbuilder 6' by Tom Cervenka. ISBN 1-884777-60-0. Also,
    check out PB verion 8. It is extremely web-enabled and may ease your effort
    quite a bit. I prefer Sybase tools to any of the others out there. IBM's
    Visual Age for Java is a nightmare. There is absolutely nothing RAD about
    it. I just came off a JAVA Application project which took 14 months with
    5 developers and I could have done it by myself with Powerbuilder in 3-4
    months. Also Websphere costs a fortune compared to EAServer.

    Picking the right tools usually requires being clairvoyant. You never know
    what the future holds for your application. Like your app.

    I'm not sure that any java tool could/should be considered RAD. There might
    be RAD features but they usually just get you into trouble and tie you to
    a certain vendor and usually make it not extendable. Creating good extendable
    systems takes time. If you want to just crank out code and get something
    working then Java (or any other language like it) may not be the best choice.
    That being said, tools like VAJ do provide the ability to generate code
    and crank stuff out. Usually, when java is chosen as the programming language
    the decision has already been made not to generate code. Now with JSPs it
    seems this is not as true. Alot of code that exists in JSPs architecturally
    doesn't belong there. I am currently working with a purchased app. It is
    a "web based" app and it performs as one wonderfully. But because of the
    way it was developed it is not extendable (obviously no one on the project
    moonlights as a medium). So I have to write custom data access code because,
    well, there are no objects. System architecture is very important.

    I feel that VAJ is a great tool for developing Java 'applications'. There
    are somethings I don't like (i.e. I can't use newer JVMs within the IDE)
    but they are being addressed. And Websphere is not that expensive (depends
    on edition and platform). Also when developing OO systems, it really helps
    having someone who can do OO design real well. That will really cut down
    on time.

    There are a lot of questions one needs to ask when designing a system and
    picking tools. Unfortunately the technology questions usually come first.
    The WHAT first then the HOW. So my question to you would be what are trying
    to accomplish with your system? How do you see your system being used in
    the future? Will your system need to inteface with other systems? How often
    will your system need to be modified/customized? etc.
