Hi,

If you need to maintain your own configuration file then search in NW help for <i>IWDConfiguration</i> will be a good start (there are references for smple usage and API docs).

Hi all,

Let me explain the scenario.

i have a Webdynpro project with a serach and a list view.

At the list view i have a LinkToUrl UI Element in a table with a dynamic url. If i work on the development system the línk may is http://192.168.1.10/TestMich/index.html, but if i at the Productionsystem the url must http://120.0.1.57/Product/index.html.

How can i trigger the system ip and port from outside, like a ApplicationConfig-Properties File with a key-value pair ?

I tested it at the moment with a local file, but i got a FileNotFound-exception. Do you hava a example for a path-description from Project root ?

I test the file-location in that way:

"temp

webdynpro

web

local

ProjectName

Temp

AppConfig.properties"

Can i trigger my application in that way ?

I have seen, that i can configure my WebDynpro-Application at DeveloperStudio over

- WebDynpro - Applications - ApplicationName - Properties - ApplicationProperties - New (Property).

At the moment, i dont know, what is the right way to configure or administrate the application.

Tahnks for help

What about creating two Web Dynpro applications which differ only in their application properties?

Or, if these URLs can be completely derived from the runtime environment, the application could construct them programmatically using the WDURLGenerator class.

Hi Jurgen,

If you are using the WDConfiguration API, you need to create a property file in the configuration directory of your web dynpro project.

Something along the lines of what they do here

http://help.sap.com/saphelp_erp2004/helpdata/en/b8/aa343e32ff1033e10000000a114084/content.htm

WebAS provides a built in tool to manage your application configuration properties as part of the j2ee visual administrator. This is under server>services>configuration adapter

The drawback of this method is that it requires a cluster restart every time you modify the property.

For our project, we have one method that takes the property from the WDConfiguration API, but also checks first if the property is overwritten in the application url using the WDWebContextAdapter.getWebContextAdapter().getRequestParameter() method. This allows us to change the value at runtime without having to go to the server and restarting all the time.
