Can't retrieve list of defined trigger types from FH

Question

In a SDL SmartTarget 2011 SP2 on SDL Tridion 2011 SP1 HR1 implementation I get this error in the cd_smarttarget log and cd_core log. It mentions a NoClassDefFoundError and says can't retrieve list of defined trigger types from FH. Which JAR am I missing?

Answer 1

The NoClassDefFoundError: com/sun/jersey/core/util/FeaturesAndProperties indicates jersey-core.jar is missing.

You need to copy those JARs from the SDL Tridion SP1 installation media:

• Tridion 2011 SP1\roles\webservice\java\third-party-lib\jersey-core.jar
• Tridion 2011 SP1\roles\webservice\java\third-party-lib\jsr311-api.jar

Without those JARs the errors mentioned above will occur and the taf:claim:ambientdata:definedtriggertypes will not be set in the ADF claimstore. SmartTarget needs this information in the claimstore and will complain by logging ERROR AmbientDataHelper - can't find defined trigger-types in claim store (check if your smarttarget cartridge is up and running).

Without the definedtriggertypes claim the SmartTarget will work, but the queries to SDL Fredhopper are not optimized.
