You can give each virtual portal a different look and feel by modifying the aggregator policies, or policy sets, that it uses.
The modified policy sets are placed in individual directories. The directory name can reflect the virtual portal name, but it cannot have spaces and must only contain the characters 0-9, A-Z, and a-z. The actual policy names cannot be modified between the virtual portals. For example, the policy wp_main.mlyt cannot be renamed.
Virtual portals are associated with the appropriate policy set in the mwp.properties file. Multiple virtual portals can use the same policy set. If a unique look and feel is not needed, the virtual portals can use the default policy set. The default policy set is created from the initial portal's policy set.
When working with the Mobile Portal Toolkit you will find the default policy set in the following directory: wp_profile_root/PortalServer/wp.mobile/wp.mobile.mwp/policies/aggregator/.
The following instructions describe the steps needed to configure a virtual portal to use a unique policy set. An example virtual portal, vp2, is used to illustrate the process.
