RE: Orion Team Needs New List Software
Someone desperately needs to replace the list software currently hosting the Orion-Interest mailing list. This is really getting out of hand. It's bad enough that everyone who posts gets messages like this from natch.se... but now they're echoing to the list as well. Isn't that a problem with the natch.se setup, rather than the list software though? If the only reason this hasn't been done is lack of suggestions, I've found use (no idea about administration) of Mailman lists to be pleasant. http://www.list.org. Is majordomo still popular? Used to be the software of choice a few years back and I never had trouble with lists that use it - nice and flexible too. Somebody said that the Orion list runs under Orion though, so I guess the Orion people have an interest in keeping it that way :-) cheers Jules
How to use CMP to find by custom types...
I am trying to implement Collection
findByTarget(Target t) throws FinderException, RemoteException, method using
Orion's CMP. My target is defined as follows:
public class Target implements java.io.Serializable
{
private long id;
private String for;
...
public long getId() {return
id;}
public String getFor() {return
for;}
};
How can I tell Orion in orion-ejb-jar.xml to
execute $1.getId() or $1.getFor() on the argument before using it in the
query? The "spirit" of the query I really want to be generated
is:
select * from myTable where myTable.i = (value of
$1.getId()) and myTable.b = (value of $1.getFor())
Thanks.

RE: Inconsistent EJB JNDI Locations
Title: RE: Inconsistent EJB JNDI Locations
A related point? (I'm new to this and a bit confused)
Purely as an academic exercise I tried to access my EJB from an external application.
The Orion documentation on this is sparse to non-existant :(
What ended up working for me is the following:
1. Write an application-client.xml (undocumented, but I figured it out from another example)
application-client
display-namePLJB User/display-name
ejb-ref
ejb-ref-namePLJB_User/ejb-ref-name
ejb-ref-typeEntity/ejb-ref-type
homecom.hotjobs.entity.UserHome/home
remotecom.hotjobs.entity.User/remote
/ejb-ref
/application-client
note: i used the full classnames for my home and remote interfaces
2. put the application-client.xml in the META-INF directory for my ejb.jar
3. redeploy my .ear
4. write the client
5. write my own getInitialContext() for this client
public static Context getInitialContext() throws NamingException
{
Properties p = new Properties();
p.put(java.naming.factory.initial,com.evermind.server.ApplicationClientInitialContextFactory);
p.put(java.naming.provider.url,ormi://localhost/PLJB);
p.put(java.naming.security.principal,admin);
p.put(java.naming.security.credentials,whatever);
return new javax.naming.InitialContext(p);
}
6. use the getInitialContext and then call lookup() using the _bean class name_(!?!?!)
Then narrowing works.
Context jndiContext = getInitialContext();
Object ref = jndiContext.lookup(UserBean);
UserHome home = (UserHome) PortableRemoteObject.narrow(ref,UserHome.class);
My questions are:
Why do I have to lookup() using the Bean class name?
Why can't i lookup on either PLJB_User or UserHome?
Am I hopelessly overcomplicating this?

Hello Manne,
That's right, that is the way we recommend it to be done. Just want to clarify
something though. It is possible to lookup EJBs in another application. To do
so, use the parent attribute when defining the application in server.xml and the
children application's local context will extend the one of the parent, making
it possible to use EJBs from another application.

Recently I was looking at the spec while trying to figure out why

out that the java:comp/env/{jms,ejb,...} locations are 'recommended',
not mandatory. Given that the non-Context contents of the env/
directory must be String objects, it doesn't surprise me that the
Orion folks decided it was tacky to put objects underneath a
directory that's supposed to hold strings. Also, I noticed when
attempting to create objects below the env/ directory using the
JNDI api, they somehow get turned into strings! I'm a little unclear
on whether this really happened or if I was doing something stupid,

RE: Why is Hypersonic SQL still being integrated
I'm willing to take over maintenance/development on this. Are people interested in keeping it alive (I know I am)? Well I'm interested in it being kept alive for all the obvious reasons stated on the list - small, free, relatively fast (for small projects anyway by the sounds of it), portable etc. It badly needs a command-line admin utility ala Oracle's SQLPlus though as Unix servers typically won't have a graphical display for any graphical management tool to hook up to. The applet - although a nice feature - which was on the Hypersonic site before it died is really out of the question - certainly having to fire up a browser just to work on the DB is too darn painful! Someone in this thread mentioned that it isn't sensible to use Hypersonic in production environments - why not? What's so wrong with it that it wouldn't work, just out of curiousity? cheers Jules

So I am dealing with iPlanet issues. But I try to keep up with Orion, even if my knowledge of it is no longer leading-edge (which is why I rarely say anything about it). I was objecting to the tone of the email that I saw. I think there is one person on a mailing-list who can and should "warn" people, and that's the owner. Period.

Common access method for homes...
I am trying to create a class than can be used to access the home of a
particular bean. For example, if I have an EJB called UserEntity, I would
create a special class called UserEntityHomeFinder which can be used to
easily obtain a home:
public class UserEntityHomeFinder {
private static final HomeFinder
homeFinder =
new HomeFinder("com.indnet.model.User", UserEntityHome.class);
public static UserEntityHome getHome() throws NamingException {
return
(UserEntityHome) homeFinder.getHome();
}
};
As you can see, this class defines the name of the home interface. I used
to use java:comp/env, however, the exception I got was that java:comp/env
was not available from a standalone client application.
So my question is this, is there a way to setup the naming conventions, so
that the CLIENT and SERVER can use uniform naming conventions to access the
homes of the bean?
Thanks.

Removal of SBs from expiring HTTP sessions ...
I posted this msg this morning, but I haven't seen it appear on the list yet. I'm reposting in case it was lost ... Session beans (SBs) must have their remove() methods called in order to "clean up" and return to an app server's object pool. I believe one common use of SBs is to create them and then bind them to HTTP sessions so that they can be reused by clients on subsequent requests. There's no standard way to tell when an HTTP session expires. How, then, is it possible for the remove() method to be called to release a SB? Does this not cause "memory leaks" to occur in two ways: 1) resources created by the SB are not released, and 2) the SB itself is not recycled?

When I have multiple web applications running on the one server - I'm having problems referencing files in other directories. eg - I can't use "/images/anImage.gif" because that references the document root. I can use "%= request.getContextPath() %/images/anImage.gif" ,but that gets tedious. Is there a better way to do it?

Empty Cookies dont work in Orion 1.4.5
Cookies set as either empty or null as in the
following:
cookie1 = new Cookie("Name1",null);
cookie2 = new Cookie("Name2","");
... both fail in Orion 1.4.5. I'm not sure if this
is fixed in 1.4.7 or not but it seemed serious
enough to report on. Orion correctly SENDS the
cookies to the browser but can't handle them
when they are returned in subsequent accesses.
RE: offtopic: Path issues
Mr Farquhar, You must always use rcp (or %= request.getContextPath() %) in front of every path to make your web app fully portable. It may be tedious but there's no other way around it besides making every path relative (which is sometimes not possible with include files etc) In stylesheets and JS files, use relative paths, this is the only way I can see to do this effectively. It shouldn't be too much of a problem though. %@ include % and jsp:include are always relative to the web app root. NOTE: All JSP commands are relative to the web app root EXCEPT response.sendRedirect() which is relative to the host (stupid spec bug!) so you need to put an rcp in front of that. -mike -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of SCOTT FARQUHAR Sent: Friday, March 16, 2001 10:17 AM To: Orion-Interest Subject: offtopic: Path issues When I have multiple web applications running on the one server - I'm having problems referencing files in other directories. eg - I can't use "/images/anImage.gif" because that references the document root.

Re: Removal of SBs from expiring HTTP sessions ...
Hello Gerald,
You can create an object that implements HttpSessionListener
interface and override the valueUnbound method to call the
remove method or whatever you need to to with the SB.
Put it in the session, and when the session expires the
valueUnbound method is invoked. Be sure to implement the
java.io.Serializable interfaz to allow session persistence across
server restarts.
We use this technique for our Shopping Cart, and it has worked
pretty well so far.
Here is the class we use:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import com.enkamino.cart.*;
/**
*
* @author Rafael Alvarez
* @version 1.1
*/
public class ControlSesion implements HttpSessionBindingListener,java.io.Serializable{
ShoppingCart cart; // This hold the reference to the SB, becuse
// you can't access to the session to retrieve
//it.
/** Creates new ControlSesion */
public ControlSesion(ShoppingCart cart) throws java.rmi.RemoteException{
this.cart = cart;
}
public void valueUnbound(final javax.servlet.http.HttpSessionBindingEvent be) {
try {
this.cart.clear();
} catch (Exception e) {
java.rmi.RemoteException re = new
java.rmi.RemoteException("Error clearing the Cart ",e);
re.printStackTrace();
}
}
public void valueBound(final javax.servlet.http.HttpSessionBindingEvent be) {
}
}

Re: Can I use InterBase's DataSource instead of Orion's?
You should not be instantiating DataSource's directly. You should define
the DataSource in Orion's configuration file, and then access the DataSource
by name via your InitialContext.

Custom UserManager.
Server : Orion-1.4.5 I've created a custom UserManager and referenced it in application.xml, I've taken out the principal tags in all the other files. Here is my problem: my custom user manager loads up and the init method gets called but that's it. The server never calls getUser on my user manager. I'm very sure I'm missing something really silly and simple but I can't find it due to the complete lack of adequate documentation. Thanks in advance. Michael L. Gantz
Re[4]: Removal of SBs from expiring HTTP sessions ...
Hello Mike,
I have to thank you. I wasn't sure of that, so I check it. I write
something like:
public interface test extends java.io.Serializable, javax.ejb.EJBObject {
void dummy();
}
And the compiler throwed and error (fastjavac from Forte CE 2.0). So I stated that it
couldn't be done.
But now, after a crash and hour ago or so, I checked again and voila!,
it compiled OK.
I want to apologize.
Thank again,
