    running jboss with -Djava.security.manager

    Brad Rust Newbie

      I have the need to make an RMI call originating from inside the jboss container (a StatelessSessionBean) to a remote jboss instance. My first attempt failed because there is no SecurityManager installed so I couldn't do any RMI classloading. So, I'm on the track of running with a security manager installed.

      running a default jboss instance with

      JAVA_OPTS="-Djava.security.manager -Djava.security.policy=server/default/conf/server.policy" bin/run.sh
      appears to startup fine. (BTW, installing a Security Manager programmatically seems to give me all the same results)

      When I get to the RMI logic, the calls succeed when a SecurityManager is installed.

      However, when I try to do *any* JDBC (via a configured Oracle *or* MSSQL Datasource), I get weird and apparently unsolvable exceptions.

      The first exception received when using either MSSQL or Oracle JDBC datasources, is a ClassNotFoundException on
      . So, looking in some jars and jboss-3.2.4 distros, I notice that the particular class is compiled but not in any distro jars. So, as a hack, I jar up two proxy related classes and stick them in my server/default/lib directory.

      The next levels of exceptions differ.

      Under Oracle (jar ojdbc14.jar), I get this...
      RuntimeErrorException: java.lang.IllegalAccessError: class oracle.jdbc.driver.$Proxy147 cannot access its superinterface oracle.jdbc.driver.ScrollRsetStatement
      Cause: java.lang.IllegalAccessError: class oracle.jdbc.driver.$Proxy147 cannot access its superinterface oracle.jdbc.driver.ScrollRsetStatement

      Under MSSQL (not sure which JDBC driver, sorry), I get this...
      Throwable while attempting to get a new connection: null
      org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (java.sql.SQLException: Failed to create Connection proxynull)
      at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.createManagedConnection(LocalManagedConnectionFactory.java:168)
      at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.createConnectionEventListener(InternalManagedConnectionPool.java:504)

      My round about point is,... what am I doing wrong with Security Manager with regard to JDBC. I am assuming that somewhere out there, someone has done what I am trying to do. It doesn't appear that unique.

      Any help would be greatly appreciated.

          What does adding -Djava.security.debug=domain,failure show around this exception? I did testing of a security manager with the hsqldb driver, but no external databases. I'll try pointbase for th 3.2.5 release.

            running with

            JAVA_OPTS='-Xmx700m -Djava.security.manager -Djava.security.debug=domain,failure -Djava.security.policy=server/default/conf/server.policy' bin/run.sh
            doesn't appear to give me any more debugging information near the exception.

            Only tested your suggested system property with an Oracle driver. Here is a clip of the stacktrace

            I can try a couple others tonight (perhaps) like mysql or postgres.

            Would you like me to turn up logging to TRACE?

            Thanks for the reply!

              It appears that firebird and mysql JDBC drivers operate correctly which running with a Security Manager.

              As you can probably tell from the stacktraces above, it fails when actually executing the statement. So, you would need an (valid?) Oracle instance/listenter to test this.
