Configuring the Web Dynpro Runtime
Environment 
Purpose
You can manipulate the behavior of the Web Dynpro system configuration using specific settings. The archive file WebDynpro.wda contains the system configuration, is part of EAR file sap.com/tc~wd~dispwda.ear and is automatically deployed to the J2EE Engine when the Web Dynpro runtime environment is installed.
You need to modify these settings for example when you use presentation graphics since you can define the Web address (URL) of the Internet Graphics Services (IGS) using the system configuration.
Process Flow
To configure some basic settings of the Web Dynpro runtime environment in file default.properties, the system administrator defines system configuration properties using the Visual Administrator.
Proceed as follows to start the Visual Administrator:
...
1.
Start the Visual
Administrator by double-clicking on file go.bat in file directory C:\usr\sap\C11\JC00\j2ee\admin, in which the J2EE Engine is installed.
You can find a description of the Visual Administrator in the SAP Library
under SAP
NetWeaver ® Application Platform (SAP Web Application
Server)
® J2EE Technology in the SAPWeb Application
Server® Administration Guide ® Server Administration ® SAP J2EE Engine Administration Tools
® Visual Administrator.
2. Navigate to directory Server 0 0_44939 ® Services ® Configuration Adapter ® webdynpro ® sap.com ® tc~wd~dispwda aus.
3.
Select file PropertySheetdefault by double-clicking.
4.
The Visual
Administrator opens so that you can edit the values. You can change or
redefine the parameters specified below.
5. Confirm your entry with OK.
These parameters are described below:
