    MySQL & JBOSS licensing question

    null null Newbie

      If one were to write a commercial J2EE app that is deployed to a JBOSS server configured to use the MySQL Connector-J JDBC driver (which is licensed under the GPL), would the application have to be GPL'd as well? Or does the application server provide enough of a seperation that this is not the case? Or is this just a stupid question...

      Thanks,

      Matt Tucker

          Correct it is a stupid question on two counts:

          1) You should ask a lawyer!!!!!!!!!!! I cannot stress this enough.
          2) Your question is better targetted at the MySQL licensing department.

          IANAL (I am not a lawyer) and you haven't paid me for legal advice
          so you should not depend on the rest of this comment.

          NOT LEGAL ADVISE

          The LGPL/GPL is about linking and distribution.
          There are no restrictions if you just use the software.
          JBoss is LGPL and is designed to work with many databases.
          The default distribution of JBoss only includes HSQLDB which has a sort of BSD style
          license.
          If *you* link GPL code with LGPL and *distribute* it, the whole distribution becomes GPL.

          If you want to distribute your application, JBoss and the MySQL driver
          the whole thing MUST be GPL, including your application.

          If you want to distribute your application and JBoss and get your customer
          to link/choose to run it with MySQL, JBoss is still LGPL and you
          can choose whatever license you like for your application.
