RE: How to get the RoleManager

Re: Multiple data sources for each application
Hi Atul. Sorry, no I do not know, although I suspect so. We are using BMP Enity Beans, due to the unusual database design (CMP won't handle it). However, our BMP EJB's do automatically deploy, and successfully create and register their own connection pools in JNDI on demand. Otherwise, our entire security and database access framework would be non-functional. You would have to look up the exact sequence of events, but there are a number of function calls made on the EJB during load and activation before any attempt is made to access the database. The exact sequence of calls is specified in the EJB specification. If you were to intercept one of these earlier calls to create your connection, I suspect that would work. We are doing something similiar. -Steve Setlur, Atul (MED) wrote: Steve, Do you know if CMP Entity Beans deploy if the connection pool is established programatically?

RE: Problem implementing Custom User Management using SimpleUserM anager
It sounds like some of you may be forgetting to create an initial account in the database ... You can't have a user in principals.xml and expect orion to know where to fetch the authentication information. I have an EJB user manager and to make things easy for my self. I protected a minimal administration site with the xml user manager.

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:
GUIServiceSBHome_StatelessSessionHomeWrapper215 was not an instance of
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
...GUIServiceSBHome but an instance of ...GUIServiceSBHome? For me the two
interface classe names look the same.
And hint why the bean is not working on the server is greatly appreciated.

Re: Multiple data sources for each application
Hi Jeff. Multiple versions of the same application at the same time? I did not mean to imply that! We only deploy one version of each application, and then let the application decide which database to connect during runtime, based on which user is accessing it at that time. If there is some way for CMP to determine which database it is supposed to connect to at any given time, based on which user is making the call, I would be interested in hearing about it. -Steve J.D. Bertron wrote: I don't think that's weird at all. I've always had applications select the database they connect to at run time, not deployment time. This seems like a major problem to me, with consequences on regression testing etc... It makes no sense to have two identical applications deployed with different datasources.xml, just so the end user can decide which DB to connect to. I can see why it's easier to have it that way from the server end, because you don't have to worry about switching a datasource on an active bean, but that's short sighted.

Re: Date conversion problem ??
Hi Eddie, The code that Fredrick Lindgren sent to this list looks like the right way of obtaining a java.util.Date from a java.sql.Timestamp. As for your question of why, part of the answer may be that three java classes are somewhat confusing: - java.util.Date (not used by JDBC) contains a date and time down to millisecond precision - java.sql.Date (used by JDBC) contains a date, and inherits from java.util.Date - java.sql.Timestamp (used by JDBC) contains a date and time down to nanosecond precision, and inherits from java.util.Date The javadoc for java.sql.Timestamp explains exactly where it stores the milliseconds (actually nanoseconds). Another question is why Sun decided to write such strange code. I'm afraid I don't have an answer for that! Nick At 10:04 AM 10/8/01 +0200, you wrote: Thanks Frederik, But what I don't understand is why Date only contains the second part and not the millisecond part and when it does ? That is, when I create a Date object and print the millisecond part with the getTime() method, I do see the millisecond part but when I receive something from the database, the millisecond part is zero. Does this mean that is only zero when the date field is handled by the JDBC part ?? Eddie snip

That won't help - I think shared sessions only work between two WARs in the same app. 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.

error serializing bean
Does anyone know what this error means?
My guess is that it's happening when Orion tries to passivate one of my
ejbs. My EJB has, as one of it's instance variables, a jndi Context:
public class MyEJB implements SessionBean{
javax.naming.Context namingContext;
}
The javax.naming.Context type is not Serializable and Orion may be crashing
on that. However, according to the ejb spec (6.4.1) it jndi Context should
be passivatable.

Synchronized session bean?
Hi everyone... I thought there was a way to synchonize a session bean such that I suppose you could say that only one user or servlet could use it at a time. 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. How to do it kinda escapes me, but let me know if there was something I missed. It would be most appreciated. No need to write volumes of code if you know of a good web site reference for example.

Jeff 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. 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. 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. Does that help any? Gary
