DITA-OT 1.2 offers new error handling and logging system. If you invoke your transformation by using java command line where new error handling and logging system is mandatory, you need to set the CLASSPATH Environment Variable for dost.jar. If you invoke your transformation by using an ant script, you need to do one more step after the setting above. That is adding a parameter in your command to invoke an ant script. For example, use ant -f ant\sample_xhtml.xml -logger org.dita.dost.log.DITAOTBuildLogger instead of ant -f ant\sample_xhtml.xml to start a transformation defined in ant script file ant\sample_xhtml.xml.
