Chapter 4. Using Web Express Logon with HATS portlets 297
4.3.2 Creating a HATS portlet project to use Web Express Logon
To create a HATS portlet project, follow the instructions and steps in 3.4.4,
“Creating the HATS credential integration portlet” on page 238. We name the
project HATS_WEL. After we create the project, we see the HATS Studio project
view as shown in Figure 4-2.

4.3.3 Configuring Web Express Logon in a HATS project
In this section, we enable and configure Web Express Logon for our HATS_WEL
project. This differs from the normal Web Express Logon process, when using
WEL together with portal server credential service. We need to configure only
the credential mapper plug-in for Web Express Logon. We do
not need to
configure a network security provider plug-in.

6. Under Details (Figure 4-8), set the SLOT_ID and SLOT_TYPE initialization
parameters. Credential mapper uses these values and other parameters to
assemble the credential slot name in the portal server. For our scenario, for
SLOT-ID, we specify the value myHATSVault. For SLOT_TYPE, we leave a
default value of 2.
