Attempting to configure the Web Portal Manager 5.1 in native mode, an error occurs: The Access Manager Java Runtime installed within the WebSphere JRE is outdated. Please upgrade the Access Manager Java Runtime."

Cause
PD.jar not updated

Answer
When attempting to configure the IBM Tivoli Access Manager for e-Business 5.1 Web Portal Manager in native mode, an error occurs:

"C:\Program Files\Tivoli\Policy Director\sbin>amwpmcfg -action config -interactive

The Access Manager Java Runtime installed within the WebSphere JRE is
outdated. Please upgrade the Access Manager Java Runtime."

Checking the java version in IBM WebSphere, it shows the version as 1.3.1.

What seems to be the problem?
Doing a search of the PD.jar file on the system, this information is displayed:

File Name
Location
Size

PD.jar
C:\Program Files\Tivoli\Policy Director\java\export\pdjrte
1,213 KB

PD.jar
C:\Program Files\Tivoli\Policy Director\java\export\pdwpm
1,213 KB

PD.jar
C;\Program Files\WebSphere\AppServer\java\jre\lib\ext
717 KB
As seen in the table above, the size of the PD.jar file is a different size than the other two files of the same name. This older PD.jar file is the one shipped within IBM WebSphere which was built for Web Portal Manager 4.1.
To solve this problem, copy the larger PD.jar file from the directory:
C:\Program Files\Tivoli\Policy Director\java\export\pdwpm
and overwrite the PD.jar file in this directory:
C;\Program Files\WebSphere\AppServer\java\jre\lib\ext
Reconfigure WPM.
