How do you set the content transfer mode to http or ucf for WDK/Webtop 5.3?

In WDK and Webtop version 5.3 applications you have the option to choose which content transfer mode the application uses.

per the Documentum 5.3 System Migration Guide:

Specifying Which Content Transfer Mode Your Application Uses

You can choose to continue using the 5.2.x content transfer mechanism, or you can
specify that your application use the new UCF content transfer mechanism. To set the
application-wide content transfer mechanism and compression for content transfer
operations on the client, use the and . elements in
the WDK application configuration file, app.xml.

The element sets the content transfer mechanism for the
application. Valid values for this element are: http (pre-5.3 applications) or ucf
(5.3 applications). If one or more of your custom components extend pre-5.3 applet
components, specify ucf.

For information about the app.xml file, see the section named "Configuring an
Application," in the Web Development Kit and Client Applications Development Guide
For a detailed description of the content transfer-related elements, see Chapter 8, Content
Transfer, in the Web Development Kit and Client Applications Development Guide.



For example you would update the WDK application's app.xml to change the content transfer mode:

For a default Webtop 5.3 install on a default Tomcat install, you would update the file:
C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\webtop\wdk\app.xml.
It is a good practice to make a backup before making any changes.

Update the element to your choice of http or ucf.


http



ucf

You will need to restart your application server.

With the 5.3 release, WDK now supports three modes of content transfer:
- HTTP (Zero footprint) -- This mode of content transfer requires no applets downloaded to your Web browser.
- UCF (Unified Client Facilities) -- This is the recommended mode of content transfer in WDK 5.3
- Content Transfer Applets (included for backwards compatibility with previous releases)


Notes on http mode:
- HTTP 1.1 needs to be enabled in IE (Tools-->Internet Options-->Advanced,. Use HTTP 1.1)
- What browser OS is used? If running on XP, the pop-up blocker needs to be disabled for the WDK/Webtop host for this to work.
You can add the WDK/Webtop host to the list of trusted sites.
