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 of the Console, select
Deployments.
In the
Deployments table, expand the application that
contains the EJB component for which you want to edit credential
mappings.
Select the
name of the EJB component for which you want to edit credential
mappings.
Select Security > Credential
Mappings.
In the EJB Component Credential Mappings
table, select 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).
