JSP Programming model for MI application development

Hi All,
While we are using JSP programming model for developing MI applications, there are some Pros and Cons for it.
one of the Cons is :-
1. JSP requires more system resources ( local web server)
Any idea what exactly does it means ?
2. When we use AWT as the programming model, do we need any additional resources to run this application ?
Thanks and Regards
Neha Mahanty

Hi Neha,
there are two different runtime options in MI - JSP and AWT - that you already mentioned corredtly.
Depending what dev model you choose, you have to install the related runtime. That is a logical step. Well, if you are aware, JSP pages are displayed in a browser and are hosted on a server. In our case MI client JSP runtime is that server and especially if you run the application on a small device like a PDA, you will see significant performance issues. The screen response time is something around 2-5seconds. this is due to the messages and the processing time of the different components.
If you use AWT on the other hand, you are running it in the MI AWT client runtime and so all runs as a single application. This has a better screen response time.
So from this perspective the decision should clearly be the AWT component. BUT!!!
If you ever have developed an AWT app, you have noticed, that it is not that easy to develop tables for example in AWT. It is possible, but it is getting complex and slow soon. So depending on the complexity of your screens it can be soon, that JSP itself has a faster rendering time then an AWT application. And because JSP screen development is taht simple, most apps are JSP apps at the moment.
With MI7.1 this will change. You have the possibility to use eSWT and WebDynpro for UI development as well, and so the development of MI applicartions that use les system performance for the runtime itself will be more easy.
Hope this helps!
Regards,
Oliver

  • Devleoper Studio and Workplace for Java application development

    1. Can someone please help me know what is netweaver developer studio and developer workplace ?
    2. I came across EP master guide that says :
    You install an AS Java centrally and the developer workplace on each developer host.
    This option is recommended for large development projects with a need for local and central testing. Developers can test their developments locally using the developer workplace. For integration tests, they deploy their changes on the central AS Java.Ûê.® |
    You install an AS Java centrally and Developer Studio instances on each developer host.
    This option requires fewer hardware resources per developer host. In this landscape scenario you can set up an AS Java in development mode centrally and connect to it from the other hosts in the landscape using the Developer Studio.
    How does Java application development take place ? Does this say that we need Developer Studio instances installed on every developer's host (suppose I have 3 developers) or do I need one server setup for Dev Studio and developers using some client program to connect to it ?
    I suppose developers create programs on their local pc's, port them to Dev studio for testing and transfer them to EP Dev server ? Is that correct.. ? Thereby, we need CTS+ to promote developments to Qlty and Prod ?

  • Performance Tuning Certification for Application Developer

    Hi,
    Can you please advise if there is any Oracle Performance Tuning certification for an Application Developer and Oracle 9i to 10G migration certification? If yes, can you please let me know its Oracle examination number?
    I have already passed 1Z0-007 and 1Z0-147 in Oct 2008.
    Thanks in advance,
    Sandeep Kumar

    ... if there is any Oracle Performance Tuning certification for an Application Developer ...There is no performance tuning related certification for application developers. There is one for the DBA track.
    Also -- to answer your question in the other thread:
    So to clear this certification do I need to re-appear all the 3 exams as they were given in 2008 or just 1Z0-146 is enough.Having passed 1Z0-007 and 1Z0-147, if you pass 1Z0-046, you will gain the certification: Oracle Advanced PL/SQL Developer Certified Professional
