java webdynpro communication

[Former Member]

Hallo to the forum,

I'm a java web dynpro newbie, I need to know if it is possible for two java web dynpros to communicate.

Is it possible to call a java web dynpro from another web dynpro, passing some parameters? Alternatively, does exist another direct communication strategy?

Otherwhise maybe it is possible to implement an undirect comunication, using cookies or putting information in local files (server side or client side)..

Can someone give me an hint? Any help is appreciated, a doc reference could be useful too.

Thank you very much.

Hi

The Communication Can be Achieved through by DC (Development Components) and making that DC as public and by that you can access that DC in some other Web Dynpro Applications

Check This and you will get solutions

HI Angelo,

If your purpose is just to access data/information from another Web Dynpro,define dependency to the other DC which you wish to access.

You can specify dependency by adding the entities you wish to expose by adding them as public parts.

However,what purpose you wish to do this for...could help.

To communicate between different Web Dynpro applications (running as Web Dynpro iViews located on one page) or any non-Web Dynpro portal content, you can use portal eventing provided by SAP NetWeaver Portal.

As it is not possible to add JavaScript coding to a Web Dynpro application, Java wrappers must be used to get access to the portal eventing.

Hi,

Please have a look into this pdf... will help u to get a clear view...of what you are looking for..<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d48eaa90-0201-0010-58a8-887fc8632c3c">How To… Program Portal Eventing</a>

The SAP Enterprise Portal 6.0 supports client-side eventing. This not only allows different Web Dynpro applications to communicate with one another but also with any iView with portal content (BSP, ITS). Although you cannot write Java Script code in a Web Dynpro application, a Java wrapper enables you to implement client-side eventing and so use portal eventing.

Hope it helps...
