RE: Error Accessing an EJB through a Bean
Don't know if this is the problem but its possible.
When you use the client the classes you reference are the ones on the server
with ejb.
When you use the other server you are referencing old version of the classes
and so you get a class cast exception.
Make sure the classes are the same.
Hope this helps.

Subject: Error Accessing an EJB through a Bean
We created a Bean to access an EJB from JSPs. First we tested the Bean from
a Java Client and everything worked fine. Then we copied the Bean to the
Orion server and tried to acces the EJB by using a JSP that instanciates the
Bean that accesses the EJB. But we can not get it to work. The test with the
Java client still works properly. But using the Bean from JSP always creates
a ClassCastException.
Here's the sniplet from the Bean where the lookup is performed.
private static GUIServiceSBHome getHome(){
GUIServiceSBHome toReturn = null;
try
{
Hashtable env = new Hashtable();
//ToDO if this bean runs inside a container this Env property will not
be
//necessary
env.put(Context.INITIAL_CONTEXT_FACTORY,
com.evermind.server.rmi.RMIInitialContextFactory);
env.put(Context.SECURITY_PRINCIPAL, admin);
env.put(Context.SECURITY_CREDENTIALS, xyz);
env.put(Context.PROVIDER_URL,
ormi://164.139.33.191:23791/bizDataNew);
// Replace EJB ModuleName below with the EJB module name identified
// in your deployment profile
Context ctx = new InitialContext(env);
Object ref = ctx.lookup(GUIServiceSB);
logger.debug(Got an Object.. Class = +
ref.getClass());
toReturn = (GUIServiceSBHome)PortableRemoteObject.narrow(ref,
GUIServiceSBHome.class);
logger.debug(Lookup5);
}
catch(Throwable ex){
logger.error( Unable to perform lookup for GUIServiceBean Home
interface\nException = + ex.toString() );
}
return toReturn;
}
The logger.debug statements create the following output.
From the Client:
de.mgi.frontend.GUIServiceProxyBean: Got an Object..
Class = class __Proxy0
de.mgi.frontend.GUIServiceProxyBean: Lookup5
On the Server (Bean used by JSP):
de.mgi.frontend.GUIServiceProxyBean: Got an Object..
Class = class GUIServiceSBHome_StatelessSessionHomeWrapper215
de.mgi.frontend.GUIServiceProxyBean: Unable to perform lookup for
GUIServiceBean Home interface Exception = java.lang.ClassCastException:

interface de.mgi.orca.business_data.ejb.session.gui.GUIServiceSBHome, the
interface it implements is
de.mgi.orca.business_data.ejb.session.gui.GUIServiceSBHome
Next to the relevant question why does the Bean get an exception when it is
executed on the server, there are also two more questions that I have when I
look at the ouput.
1. Why is the return value of ref.getClass() different? The client and the
JSP are accessing the same EJB on the same Orion server.
2. Why does it says the retrieved object is not an instance of the interface

Ok. I had the same problem. It was, that I had one and the same class
(the Home Interface) in two places. Both classes, though identical these
classes were not compatible :(.
It is possible (like in my case) that you have the home interface both in
the ejb-jar and the web-app. Try removing it from the web-app.

RE: Synchronized session bean?
Simply put if there's $5 left in the bank, you wouldn't want to have a user withdraw $5 with two different web browsers if they hit submit at the same time... so we kinda want it to be like there's only one teller window, and the servlets have to wait their turn. A poster already mentioned that simplistic solutions might not work in a clustered environment. I agree that designs that work due to timing or happen stance that may not remain constant are weak designs bound to have problems in deployment. This problem is the the classic stale update scenario. Multiple clients show $5 available to with draw. They all hit submit at once. How to guard against an over draft in a robust and repeatable in all scenarios way?? The most offered solution that I've heard and I've implemented uses optimistic concurrancy guarded with a row version number; - add a version number or modification date to your data base tables. I use a sequence number that trigger auto-increaments on update. - Your Model class (represents a data base table row) returned by DAO's and Entities include the sequence number. - Your presentation tier has a reference of the model (including the row version number) and all display $5 and internally held in the session is an instance of the Model used to generate the dynamic data by your View (MVC) component. - All users hit submit. - The Controller (MVC) processing this event fetches the Model from the session and calls the setter to modify withdraw ammount, passes this Model to the Business Deligate to access your transactional layer (mediated by a Session bean calling Entities). - The Model instance is serialized and passed as an argument to the layers of business components down to the Entity responsible for updating the AccountBalance table row for this account. - I used BMP and DAO objects to package the SQL logic. My DAO fetches the sequence number from the Model and account new balance from the model and builds the SQL prepared statement: UPDATE account set balance = ? where column_version_num = ? ; I call stment.setString (1, model.getNewBalance()); stment.setString (2, model.getVersionNumber()); If I get a SQLException on this update, then I know that someone else beat me to the $5. The key concept is the WHERE clause will only update the row IFF the sequence number has not been changed by someone else (meaning I had stale data). This will work in clustered environments at all times and does not depend on synchronized business delegate methods or any other design that is likely to be defeated by appserver servlet or object pooling or use of multiple VMs to host your application. Good luck, curt
Re: Synchronized session bean?
** Okay guys, I've updated this email with a decent example I hope ** Access to each session bean instance is serialized, but the spec doesn't specifically allow you to say there may only be one instance of a particular session bean class. ** so in otherwords, pretty much it achieves the effect I wanted with little effort... that's kinda nice... and it does this no matter what isolation/transaction level I request or would you recommend a few settings? Access to entity beans is also serialized and you can be certain that, in a a given app server instance (neglecting clustering issues), there's only one instance of a particular entity bean class + primary key. okay, so if I have two servlets, if I change the value of say foo of an entity, the other servlet upon say reading the value foo will see the new value automagically? Even if I don't do another finder call? It sounds to me like your talking about something much more like an entity. You can still get the guarantee you're looking for if you access the entity through a session bean, but the guarantee comes from the properties of the entity bean, not the session bean. Well I thought of using the session bean because I'm kinda trying to perform an action that has three steps: 1) check balance 2) deduct from account 3) credit new account But the problem comes not from making sure there's only one copy, but the (I think you call it) a race condition. Say $5 in bank account A, and we want to pay account B $4 and account C $3. Servlet 1: Task: Pay Account B $4 from Account A Servlet 2: Task: Pay Account C $3 from Account A Servlet 1: 1) Check account balance Yup $5 is more than $4 Servlet 2: 1) Check account balance Yup $5 is more than 3 Servlet 1: 2) Deduct $4 from Acct A Servlet 2: 2) Deduct $3 from Account A (must be okay since the check was okay in step 1) Servlet 1: 3) Credit Acct B $4 Servlet 2: 3) Credit Acct C $3 End result, balance on Acct A is -$2 even though we checked to make sure the entity had the correct balance. Yes the ending balance is correct too! But the end result is _undesirable_ since we should have prevented Servlet 2 from completing execution and throw an exception. So I hope to make the task Synchronized such that Servlet 2 is Blocked until Servlet 1's transfer task is complete such that the following is observed Servlet 1: Task: $4 from A to B Servlet 2: Task: $3 From A to C Servlet 1: Call Session Bean to Xfer funds stuff happens 1) ... ok Servlet 2: Call Session Bean to Xfer Funds 1) ... can't check yet, the Session bean is busy with session 1's request -- Blocked -- Servlet 1: .. more stuff happens... 2) ... deduct 3) ... deposit -- Finish -- Servlet 2: -- Unblocked -- 1) .. continue... check... too little money ** Throw Exception -- Finish -- So yes in both cases the Entity reacts as programmed, but it's the Session Bean I hope to change the behavior of. Is the desired behavior the default way of execution or do I have to do something special? Does that help any? yes it does, and don't get me wrong, I trust what you're saying, but I just ask a little more to make sure I understand all the little unsaid details ;) Thanks again!

Orion on Linux, Follow-up Question
My previous problem, starting Orion on linux, was due to the fact that I was calling upon the wrong JVM (even though I thought I had my path set correctly). That is resolved. Now I have another problem that seems more linux-related than Orion-related, but perhaps some of you know the solution. I have Orion running on linux, and from that machine I can access Orion-served pages. But I cannot do so from outside that machine. What's more, I am unable to run it on a user account. For now, I'm running under root. But like I said, I cannot connect to it from another machine. Upon doing some investigating, I have discoverd that when I try to connect from another machine, Orion is sending the HTTP headers only and then freezes without sending anything else. The page never loads, it just hangs indefinitely. I strongly suspect this has something to do with linux and not Orion. I cannot run Orion on a user account because it tells me I don't have permission to run an HTTP server. I don't get that message as root, but I wonder if there is some linux mechanism at work blocking my attempts to transmit data via HTTP.

RE: Error Accessing an EJB through a Bean
We got it to work, thanks to the help of Simon Knott and Lachezar Dobrev.
The reason was that the class file of the EJB was in multiple archive files.
Simon also added a - in my opinion - good explanation why it didn't work to
his reply. I will post here now with his permission, as he replied directly
to me.
Simon wrote:
If this is the case [having the class in multiple archives], then what is
likely to be happening is the following:
1) JSP class loader loads the EJB class into memory, from the WAR file.
2) JSP does a lookup for the EJB object.
3) EJB container class loader loads the EJB class into memory, from the
JAR
file.
4) EJB container returns its loaded class to the JSP
5) Class cast exception is thrown.
Now the key point here is that different class loaders are used for both
the
JSP and the EJB container. When one class is loaded by two different
class
loaders, they are essentially different classes, with different class
signatures.
What happens with the class loader is that it takes the quickest route to
loading a class - in the case of the JSP it will get it from the WAR, in
the
case of the EJB container it will get it from the JAR. What you really
need
to do is to create one archive, which is then placed in either the
webapp/lib directory or the orion/lib directory, and exclude the EJB
classes
from the WAR and JAR files. This means that the classes in this one
central
JAR file will only be loaded by one class loader, removing the problem.
This does not occur on the standalone client, because it uses only the
system class loader, no others.

FW: How to get the RoleManager (resend)
-Original Message- From: David Potts Sent: 11 October 2001 10:02 To: 'Orion-Interest' Subject: RE: How to get the RoleManager inline -Original Message- From: Mike Cannon-Brookes [mailto:[EMAIL PROTECTED]] That won't help - I think shared sessions only work between two WARs in the same app. We could probably live with merging the two apps into WARs in the same EAR file. However, we've just tried that with a test app and with the shared flag set to be true in both of the web-app tags in default-web-site.xml (and also in default-web-app for good measure!) and we have the same problem: the second app again goes to the login form. Any ideas of what config we might have go wrong? Juan Lorandi in this thread mentioned putting shared=true in orion-web.xml but we can't find that in the docs. What tag attribute do we apply this to? Juan also mentions the same realm name, but this is just for BASIC authentication I believe, and we unfortunately have to use FORM based authentication. Is that right? The only thing I can suggest is using some sort of cookie based system where you track via session ID who is logged in (stored in a hashmap or something), then from each app lookup that hashmap (via JNDI) and log in the user programmatically before they are shown the login page. Very fugly though. SSO is one of J2EE's problems. So the flow of that solution would look like: (1) User logs into app1 (2) Store user info in JNDI somewhere that app2 can see it (3) The user clicks a link that would take them into app2 (4) Intercept the login-request and use the stored info to log the user into app2 The problem with this flow is that we don't know how to intercept at step (4) *before* the user is shown the login form by the container. Is this possible? If not, our idea similar to this would be: (1) User logs into app1 (2) Convince the app2 security (RoleManager?) that the user is logged in using the values passed to app1 (3) The user clicks a link that would take them into app2 and is already logged in Hence the original question in this thread: how from app1 do we get hold of app2's RoleManager? Thanks for all the help. Dave.

Greg, In your *web-site.xml files, you will need to set shared=true in your default-web-app and web-app tags. The bug you have encountered is an IE bug.

problem using primary key class with orion
I am having some difficulty getting orion to use my primary key class during deployment. I have an EJB AnyPerson with which I use a primary key class AnyPersonKey that has a public java.lang.String primaryKey field. During deployment, I get a compilation error that looks like the CMP isn't being generated properly. The orion-ejb-jar.xml file looks fine, as does the ejb-jar file. I get this error on deploy: Auto-deploying kwu-ejb.jar (Classes were updated)... Error compiling C:\orion\applications\kwu-phase-2\kwu-ejb.jar: Incompatible type for prim-key-class and type of the specified primkey-field: Cannot convert from class com.kw.kwu.model.AnyPerson.AnyPersonKey to class java.lang.String It doesn't seem to recognize that I'm using a primary key class at all, even though it is mapped in the orion-ejb-jar.xml file. Has anyone got a working example of this? I'm tired of tweaking the orion-ejb-jar to try and get it working.

Re: WebLogic To Orion
Greg, This has been covered in previous postings. Here's a quote from one of them (start quote) This is a configuration problem... at least it was in earlier versions. You must make sure to include the attribute 'secure=true' in the web-site tag of your secure-web-site.xml file. Also, make sure that the attribute 'shared=true' appears in each web-app tag in this same file. This cleared up the problem for me.

Re: WebLogic To Orion
Why Orion? Because from day-to-day, no matter how many CPUs, no matter what the BEA Sales Executive's outstanding Mercedes lease payment, no matter what...Orion is USD$1500 / physical server license for deployed applications and every developer seat is free...because IT management need never again sweat out BEA 'Assistance' shakedowns and audits... http://www.orionserver.com/purchase.html compared to no stated pricing (it averaged USD$35K/CPU last year as an average quoted price at 7 of my clients) on the BEA website with developer seats requiring additional license and support fees... In addition, to quote David Jones' Review of the freeware JBoss in the serverside.com (link: http://www.theserverside.com/reviews/thread.jsp?thread_id=6215 ) Application development, which is what people do with app servers, is a very technical thing. It requires experience and knowledge. Support services do not help in any way with this. If you want this, you pay for a class with BEA or JBoss. BEA has a newsgroup to help out, so does JBoss. If you want more you can talk to someone at BEA, that's more difficult at JBoss. But do you want to know what they will tell you at BEA if you ask a tough question? The same thing that JBoss tells you without getting you on the phone: pay us consulting fees and we will help you fix it. By the way, that's what Orion and its partners will tell you, too...for a lot less than the BEAst, and with a lot less stress on your IT and corporate management. Michael J.
