anonymous wrote : java.lang.ClassNotFoundException: org.jboss.ejb.plugins.keygenerator.hilo.HiLoKeyGeneratorFactory (no security manager: RMI class loader disabled)] All you have to do is, make sure that the standalone client has the appropriate JBoss jar file(s) in its classpath. You dont have to do anything related to the security manager. I usually place the jbossall-client.jar (present in %JBOSS_HOME%/client folder) file in a standalone client's classpath. I am not sure which jar file this org.jboss.ejb.plugins.keygenerator.hilo.HiLoKeyGeneratorFactory class belongs to. You might have to search through the jboss jar files and find the appropriate one.
