Unable to locate the audio cache. Check that the VXML DTPlayURLPlugIn is defined in the configuration database
The system appears to have started normally (dtjstart was successful), but the error written to Node1.out indicates that a cache has not been created (cache is a key prerequisite for successful system functioning). Ensure that you have defined the cache plug-in as part of the TTSService entry, and ensure you have referenced the cache plug-in the NodeName entry, in the default.cff configuration file.
To solve this problem for all speech browsers, edit the TTSService entry or NodeName entry, or both, run dtjconf and restart the node with dtjstart.
