Iview development - best way forward

[Former Member]

Hi,

I am currently working on EP 6 installation. The SAP backend is 6.20.

I wish to write an iview that accesses the backend, can launch other iviews and also read the UWL XML configuration file on the portal.

What is the best means of developing this. I assume a Java iview using the JCo- if so what developer tool do I need (Eclipse with the portal plugins? NWDS? ).

I'm comfortable in ABAP,BSP,Java and C# but I just need to know the best way forward for this scenario.

Regards,

Dan

Netweaver using portal perspective, do you have Java Developer access in the portal?

IF you need any clarification or help with the java side let me know it is very easy to set up and follow some of the examples they have

My suggestion is to write a BSP application -just because you are familiar with it-, integrate it into EP and use the EPCF for eventing.

If you decide to develope a Java IView you do this in the NWDS in the EP perspective, you're right. All plugins you need are already inside the NWDS.

An other and easy way to create an IView is the Visual Composer - you can connect to R/3 with BABIs by VC.

By the way take a look at WebDynpro, a very important UI technology also for the EP with great advantages...

Hope this helps...

Thanks very much all for your help.

If I use BSP, will I be able to read the UWL config file?

As for web dynpro - what are the requirements - can I develop just for the portal with web dynpro - i.e. I don't need a 6.40 back end?

Correct WD would not be an option. I actually use Java with JSP's instead of BSP's also you can access UWL config

If you have Java Developement installed on your portal click on Java Development then User Interface Development - HTMLB then getting started. JCA is a way to access SAP R/3 something Java has had for a very long time. Meaning it's kinda like a datasource you can call. There is code to get the users credentials within the portal letting the portal map the R3 login credentials. Hope this helps

JCA is the recommended way to access SAP Systems if you are thinking abt Java Iview inside your portal!

Search SDN for docs on JCA, You wud find code samples..

If you have PDK installed in your portal, you could also check out the documentation on JCA!!

Post back for specifics!!
