    JBossCache with Firebird (using Jaybird driver)

    Ryan LeCompte Newbie

      Hello,

      I am trying to JBoss Cache working with a Firebird database using the Jaybird JDBC driver. However, when I start up my example I get the following exception (see below). I am sure this is because of the BLOB type size limitations, however I'm not entirely sure. I know there is a workaround for Mysql to use "longblob" instead of "blob" in the configuration file. Is there something similar for Firebird? Any help is greatly appreciated.

      Thanks,
      Ryan
