This Problem is solved. I removed PortalIdentity.jar and download SEAM 2.1.2.CR1 with this version I can use the old login of SEAM..........
First of all the PortalIdentity bridgelet is added to the booking demo using a profile, so you remove it by commenting out the following in the pom.xml:
<id>sso</id> <activation> <activeByDefault>true</activeByDefault> </activation>
Both CR2 and B4 have same functionality as far as integration of components.
the cargo error occured because you were not in the right directory, cd to the child directory "ear"
The newer CR2 PortalIdentity only works for newer seam versions, so yes you have to use it.
