In version 12.6.6 of Identity Portal the endorsed folder was copied manually to the application server.
In 12.6.7 version, the installer was supposed to do this automatically so this step is not documented.
However, the installer is not performing this action and the manual step is still needed.
The relevant files are located in the endorsed folder under the installation of SIGMA:
SIGMA_BASE_FOLDER\SIGMA\jdk-endorsed-jars
Each application server deals with the files differently.
In JBoss copy the two JARs to the JDK endorsed folder (if it does not exist then create it).
After you complete this step, the JDK endorsed folder should have the following content:
c:\Program Files\Java\jdk1.6.0_45\jre\lib\endorsed\geronimo-jaxws_2.2_spec-1.1.jar
c:\Program Files\Java\jdk1.6.0_45\jre\lib\endorsed\jaxb-api-2.2.6.jar
In Tomcat, create a folder named "endorsed" under the Tomcat home folder:
c:\Tomcat 7.0\endorsed\
Copy the two JARs to the JDK endorsed folder.
After you complete this step, the JDK endorsed folder should have the following content:
c:\Tomcat 7.0\endorsed\geronimo-jaxws_2.2_spec-1.1.jar
c:\Tomcat 7.0\endorsed\jaxb-api-2.2.6.jar
Restart the Tomcat application server.
