You can edit EJB 2.X
component credential mappings.
If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
In the left pane, select
Deployments.
In the right
pane, expand the application that contains the EJB component for which
you want to edit credential mappings; to expand an application, click
+ next to the application name.
Within the
expanded application, locate and click the name of the EJB component
for which you want to edit credential mappings.
Click Security > Credential
Mappings.
In the EJB Component Credential Mappings
table, click the credential mapping you want to edit.
Edit the information in the Edit EJB Component
Credential Mapping page as desired.
Click
Save.
To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
