My webapp complains about not being able to find: com.tridion.smarttarget.ambientdata.session.SessionProcessor.

Where is this located? I cannot find any com.tridion.smarttarget.ambientdata. I looked in jars such as:

  • cd_ambient.jar
  • smarttarget_core.jar
  • smarttarge_cartridge.jar

It's on SDL Tridion 2011 SP1 (probably HR1)

Full error:

  • I got this error when I enabled session_cartrigde_conf.xml in the cd_ambient_conf.xml. I did not expect to that to use any SmartTarget stuff. I did not investigate this, so there might be something else which causes this error to occur at the moment when I enable session_cartridge_conf.xml.

1 Answer 1


It is the session_cartridge.jar which is part of SmartTarget

It is located in the Ambient Data Framework\cartridges folder on the cd layout
