After running the setup script for the ssoadm utility, trying to run ssoadm returns a NoClassDefFoundError error. This problem occurs for an upgraded OpenSSO Enterprise instance.
Workaround. To use JSS, add jss4.jar to the classpath and set the LD_LIBRARY_PATH environment variable. (If you are using the default JCE, jss4.jar is not required to be in the classpath.)
