To edit an existing Web application configuration file or Web services consumer configuration file
Select the Open command from the Web Runtime Configurator File menu.
In the common File Open dialog that is then displayed, select the configuration file that you want to edit. The pane at the right of the Web Runtime Configurator window is then populated with the appropriate information, as shown in the example in the following image in which a file called e:\temp\webappconfig.xml was selected.
Expand the node in the pane at the left of each configuration file entity whose values you want to display in the pane at the right of the window.
To edit the configuration file, click in the appropriate row in the pane at the right of the window and maintain the value in that row to meet your requirements.
Repeat step 4 of this instruction for each value that you want to maintain.
Save the file.
