Dear orion users, I am faced in problems with rmi-client, in web container I have a rmi client that perform a lookup in an rmi-server (a simple application, where the rmi-client will lookup to rmi-server and the object in rmi-server, just execute a external native application), the simple app, just has a method doLogin (), and nothing more, the problem is in getting SecurityExceptions, in line where I am performing the Naming.lookup ("rmi://rmi-server/myReference"), before the lookup I am setting the System.setSecurityManager (new RMISecurityManager ()); (but before this I am verifying if orion has a System.getSecurityManager==null, and doesn't has one). When I perfom this rmi-client from a single dos prompt (in same server machine), all works fine, and this perform good from J2EE 1.2.1 RI too. So, if anyone known anything, please response to list. very thanks 4 all Claudio Miranda
