You will also get this alert if your certificate doesn't exactly match your url with domain name that you used to get the certificate... https://secure.mycompany.com will work if that is the domain name registered with the certificate. But if you are on a intranet, and the server name (mycomputer, for example) doesn't match the domain name, you will get this error.

RE: Session cookie and https. PLEASE HELP!!!!
basically, cookies are URL spec (as per the spec, check it out in Netscape Central) URL dependant; if you send a cookie for a URL http://www.yahoo.com then that cookie is valid for that URL only; that cookie won't show up for URL https://www.yahoo.com (note the different protocol, https, instead of http); there's a way to make a cookie public for all URL's, but of course, that might compromise security; that's what orion does when you set 'shared="true"'.

Re: EJB Clustering
william, look for the clustering guide on www.orionserver.com in the documentation section, then maybe post some more questions once you've given it a try. it works like you describe, in that starting the load balancer takes all requests and redirects to instances of orion. cheers, greg. - Original Message - From: William Jones To: Orion-Interest Sent: Friday, March 09, 2001 7:32 PM Subject: EJB Clustering I would like to find out if anybody out there has done much with clustering EJB (or RMI) servers using Orion. We will be running an operation that will need to be large, scalable and have a failsafe level of availability. In other words there should be no single point of failure. Obviously running a single EJB server will lead to a single point of failure in the infrastructure (and obviously limits scalability also). What we sould like to do is have the ability to run several clustered EJB servers so as to provide the ability to scale (add more servers to the cluster) and failover (if one falls the others pick up the slack). The classic solution to this sort of clustering (e.g. when done with web servers) is to place a local director in front of the cluster. Then all requests are sent the the IP of the local director which just routes them through to one of the machines in the cluster. The obvious problem when doing this with RMI/EJB is that when the remote interfaces (well, stubs really) do a bind() into JNDI the IP address of the machine is bound in with it. This means that requests made through that stub will go back to the machine doing the registering and not the local director, which defeats the local director. Weblogic supports clustering by providing its own (proprietry, yuk) version of rmic (c.f. http://www.weblogic.com/docs51/classdocs/API_rmi.html#compiler), but I am not aware of anything similar in Orion. (By the way, please can no-one interpret this comment as being anything of the "WL is better than Orion" sort... it is clear most of us that Orion is superior in most aspects). For RMI we have implemented a solution that invloves binding different instances of the same RMI service as different entries in the same JNDI directory and using a central service (or array of them) to pass out the stubs from the JNDI tree in a round robin fashion to clients that request them. (e.g. two services to implement logging bind to "rmi/com/amc/system/logging/LoggingService/bart" and "rmi/com/amc/system/logging/LoggingService/homer", clients make a request for com.amc.system.logging.LoggingService.class and receive back a stub for one or there of the services). I can't see that this approach will work with EJBs as you don't seem to have control over to where in the JNDI tree the stubs are bound (the mapping of JNDI name to remote interface is done in the application-client.xml!) Can anyone give me any insights on other ways to approach clustering of EJB services using Orion? Thanks in advance... William Jones asset-management.com
mime types for .js
There seems to be a *feature* of NS browsers that requires a server mime-type for any javascript which is referenced in a web page.

RE: UserManager
The easiest way is to use the EJBUser usermanager. You will need to refer to the ejb in your ejb-jar.xml. There is an orion security adapter available for the petstore example, and this works well with the EJBUser usermanager as long as you have the entity bean reference as noted below. Of course, you will need to specify your security roles in the web.xml document. We use this entity reference in our ejb-jar.xml: EJBUser EJBUser management com.evermind.ejb.EJBUser com.evermind.ejb.EJBUserHome com.evermind.ejb.EJBUser com.evermind.ejb.EJBUserBean Container java.lang.String False username password description locale certificateIssuerDN certificateSerial groups username -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Sergei Batiuk Sent: Sunday, March 11, 2001 10:51 AM To: Orion-Interest Subject: UserManager Could anyone please explain how to create a custom user manager for Orion?

Re: JDom and Orion
Well, David Kinnvall, did you ever get into any trouble from replacing the versions of Xerces and Xalan in Orion? Randahl Hi Mark, and the list, I ran into this as well, just two days ago. I tried putting the new xerces.jar in WEB-INF/lib as well as in orion/lib, with no effect. Finally I simply replaced the $ORION_DIR/xerces.jar with the new one as you are thinking about. It worked nicely, and I have not seen any ill effects from it yet. JDOM is very nice! I guess your question is still valid though: Are there any bad effects from doing this that will surface along the road that I haven't seen yet? Something that is not triggered by my current code? Or is Orion compatible with newer versions of Xerces? Oh, almost forgot, I took the opportunity to replace the old Xalan with the latest one as well... Regards, David.

EJB encapsulation (data hiding) pattern... Is there such a thing?
I am trying to model a Person having many Phones with two Entity beans. Person and Phone are both entity beans. But I do not want to allow anyone to manipulate the Phone directly. I only want Person to be able to: Person.addPhone(PhoneValue) Person.removePhone(PhoneKey) Person.updatePhone(PhoneKey, PhoneValue) Person.getPhones(). In other words, Phone is treated like a dependent (except on advice of others, I have stopped using dependent objects). Is there a way I can enforce this? In other words, how can I stop any one except Person, from using the PhoneHome/PhoneBean directly? The reason I need to do this, is because Person performs additional logic when phones are added or removed or changed. This logic, must always be performed, so I do not want someone to use the PhoneHome to find the Phone and change it without the person knowing. -AP_ www: http://www.standardset.com resume: http://www.standardset.com/resume_body.jsp home: (818) 541-0029
Implementing CMP finders with non-native argument types...
I am creating a finder which takes a type of Target object to find. So, my home interface looks like this: Collection findByTarget(Target o) The SQL I want to ultimately generate should look something like this: select * from myTable where id = ?1.getId(); Please note, that what's stored in the table is something called id, but I need to extract that id from the Target by using the Target.getId() API before using it in the SQL. Is there a way to do this, or are CMP finders always doomed to accept only primitive types? Thanks. -AP_
