Re: Best way to add user records to EJBUserManager...
Instead of coding to EJBUserManager directly, I would highly recommend you check out OpenSymphony's OSUser module. It is an abstracted user management layer that works with Orion, Jboss, and Resin, and soon Weblogic, Websphere, and JRun. Using OSUser will truly make your application work on any J2EE application. -Pat - Original Message - From: Alex Paransky [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Sent: Monday, January 07, 2002 9:43 PM Subject: Best way to add user records to EJBUserManager...

RE: JMS hangs on TopicSession.createSubscriber
I found several references to this bug in the mailing list archives but it still seems to be a problem (in 1.5.2). The workaround suggested was to stop the TopicConnection associated with the TopicSession and then do the createSubscriber and then restart the connection but when I do that, it hangs in the TopicConnection.start() call. Does anyone have a fix or workaround for this? Thanks
Follow-up: Deploying Orion1.5.2 App on WebLogic6.1
Sent an email a while ago about migrating an app developed on Orion 1.5.2 to WebLogic 6.1 and as requested amletting you know about the 'quirks' I encountered! As its an intranet app and aint gonna have that many hits I didn't opt for using Apache to server static content, but my impression is that if you are gonna get a lot of hits they recommend using Apache. Setting this up didn't look that complicated and there are plenty info on doing this. If you are using Oracle and the type4 JDBC drivers, there are quite a few issues WebLogic has. For example, if you do a select for update and autocommit is on, it messes up. Cant list them all, but had to do quite a few tweaks to the code to get it to work. There is a lot of information on these issues and I recommend reading it thoroughly before (which I didn't :) Its understandable why Oracle are using Orion for their app server. In terms of Deployment, Weblogic 6.1 is really designed for EJB 2.0 and deploying appsas ear, war, and jar files via the gui console. But as I built mine exploded and EJB1.1 it was a bit fiddly to get it to work, but not impossible. The biggest prob I encountered was that it doesn't automatically generate its version of orion-ejb-jar.xml (weblogic-ejb-jar.xml). You have to create this yourself but its not complicated. I had problems with the servers mime-types. If you have any odd mime-types (and by odd I mean a ms word file) you need to specify mime mappings in your WEB-INF/web.xml . There is no mime list like the file mime.types in Orion. Overall, most of the problems I had was really figuring out how WebLogic works. It is way more complicated then Orion, which I think is intentional on BEA's part, and really really expensive. After using WebLogic, I have become an even bigger fan of Orion! Hope you find this info useful. If you have any questions let me know!

Orion dies to java.lang.VerifyError

jms problem
hi !
i am trying to subscribe to topics from my java standalone client
application. everything works fine if i use OpenJMS with Orion Application
server. when using orion's JMS server i run into the following problem:
the client successfully subscribes to the first topic, but hangs when
subscribung to the second topic while calling createSubscriber in
TopicSession.
here is a code snippet:
public OrionJMSSubscriberWrapper(Context context,
TopicConnection connection,
String topicName) throws JMSException,
NamingException {
subscriberSession = connection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
topic = (Topic)context.lookup(topicName);
Trace.mar(create subscriber);
subscriber = subscriberSession.createSubscriber(topic, null, true);
Trace.mar(created subscriber);
}
as i said, the first topic works fine, the second hangs at the
createSubscriber line. i changed the order of the topics, it is always just
one that is subscribed successfully.
anyone ever had this problem?
thanks for your help!

question about ip allocation
Hi I'm sorry if this is a newbie question, but I haven't found the answer in the archive. My machine has two IP addresses. In my web-site.xml I have specifically set Orion to use one of those ip addresses. It only answers on that specific ip address. However, when another server (IIS) tries to use the other IP adress on the same port number (80), IIS refuses to start as it replies (Address already in use) Does anyone have a solution?

Passing Interface as an EJB parameter?
Hi: Is it legal to pass an interface like List as a parameter to a remote interface of an EJB? Conversely, how about returning an interace like List as the return type? Since List is an interface and not serializable, I wonder if it would be marshalled/unmarshalled correctly. Thanks, keith

Re: Passing Interface as an EJB parameter?
Legally You can declare return types any Interface though the interface may not be extending from Serializable. The marshalling and UnMarshalling happens on the object at runtime the object which you are returning must be serializable.

user manager, principals shutdown
I need some help fixing something I broke. I stepped through the user manager tutorial on orionsupport ( http://uk.orionsupport.com/articles/usermanager.html ) and managed to put BASIC authentication on a certain directory on my site. But since then, it seems I deleted the information that allows the shutdown command java -jar admin.jar ormi://localhost admin x -shutdown this command looks up the username/password in the custom UserManager and always returns Security error: Invalid username/password for default (admin) I would prefer that the server admin the users in the custom UserManager be kept separate. is my principals.xml meant to have two different groups? can the server admin user remain in the xml config as it is when first running orion? user username=admin password=x deactivated=false my application.xml: user-manager class=com.orionsupport.security.MyUserManager / should there be two different entries here??? one for the BASIC authen, and one for server admin ? my web.xml: security-role role-nameadministrators/role-name /security-role login-config auth-methodBASIC/auth-method realm-nameadmin tool/realm-name /login-config security-constraint web-resource-collection url-pattern/admin//url-pattern /web-resource-collection auth-constraint role-nameadministrators/role-name /auth-constraint /security-constraint my principals.xml: (however the user is just ignored, and the MyUserManager is always used to validate both users) principals groups group name=administrators descriptionadmin tool users/description permission name=administration / permission name=com.evermind.server.AdministrationPermission / /group /groups users user username=admin password=admin deactivated=false descriptionThe default administrator/description group-membership group=administrators / /user /users /principals I hope all that made sense thanks tim
RE: OrionRemoteException: Error (de-)serializing object:
Yeah you have to return an arraylist or a vector, i.e something that is
serializable. It is never a good idea to pass ResultSet objects around.
Although it is attractive in terms of changeability (eg adding more fields
etc) to use a ResultSet, it can become a nightmare when there are network
problems and you can leak connections if you don't handle the exceptions
properly.
If you are using ejb's then the whole idea is that the EJB is an object
version of the data so that you can work directly with the object. If you
want to use a ResultSet directly in the jsp (useful for reporting etc), just
open the connection to the database directly in the JSP and do your query
and close it again. If you are doing something more invovled you might want
to user a few beans/taglibs (there are some nice jdbc ones around) just to
stop your jsp pages from becomming a spiderweb.
Your DBManagerBean looks dangerous - there is a pretty good chance you are
going to leak connections. Rather use just a normal bean that you can
instatiate locally at the jsp side or the ejb side. Thus there is no need to
use an ejb to control connections.

Manuel
