Re: Serialization from Orion back to Client via Session EJB
I've had some problems with client 1.4 and server 1.3.1.
Can't remember wich errors, but I think you have to use the same jdk on

Subject: Serialization from Orion back to Client via Session EJB
I have a number of code tables in the database, that will only ever be
read only. Rather than creating the infrastructure of an Entity EJB for
these tables I would like to simply call a session bean to return read only
versions of these codes.
A typical class has the form
public class CodeClass
implements Serializable
{
private long code;
private String name;
public long getCode() { return code;}
public String getName() { return name;}
}
I've created a Session EJB that accesses the database using JDBC to return
the entries to the bean.
This bean uses these entries to construct instances of CodeClass and
inserts them into a Vector.
This vector is then returned as the result of the method call on the
Session EJB.
The client receives an error from the server indicating that the CodeClass
indicating the class could not be (de-)serialized.
The Client is 1.4.0, orion is 1.3.1 (Oracle extended version), I've
tested to ensure that this simple CodeClass can be read/written between
1.3.1 and 1.4.0 and there appears to be no problem there.
I'm a little stumped at this point, as the code seems to be very simple,
compiles and doesn't run. Is it the fact that I'm returning a Vector? Or
am I missing a step, or

Re: No influence on CMP 2.0 getter setter methods - a feature or a bug?
Hi Randahl,
Why don't you just leave the method setBalance(float b)
out of the remote interface and put
public void setBalanceAndDoWhatHasToBeDoneWhenYouSetBalance(Float balance)
in the remote interface. So no other objects can call setBalance but only
setBalanceAndDoWhatHasToBeDoneWhenYouSetBalance(Float balance).
Greetings Wim Veninga.

Subject: No influence on CMP 2.0 getter setter methods - a feature or a bug?
I have been reading the CMP 2.0 specification and I think it is simply
great! Still, I am a bit surprised that the bean developer has no control
over what happens when a field is set. Imagine an AccountBean, for
instance:
public abstract class AccountBean extends EntityBean {
//implemented by the persistence manager
public abstract Float getBalance();
//implemented by the persistence manager
public abstract void setBalance(Float balance);
}
What if I wanted to do something useful when the balance was set? Say, I
wanted to add the account to a list of surveilled accounts if a negative
balance was set... it seems I cannot do that because the container
implements the setBalance() method for me. And I cannot just declare a
setBalance() method myself because I need the container's implementation
or
I will not be able to store the balance. H... it seems this is going
to
leave me with something like
public abstract class AccountBean extends EntityBean {
public abstract Float getBalance();
public abstract void setBalance(Float balance);
public void setBalanceAndDoWhatHasToBeDoneWhenYouSetBalance(Float balance)
{
//check if balance is negative and take action
...
setBalance(balance);
}
}
Now I have _no_ guarantee that nobody will accidently call the original
setBalance() method, thereby circumventing my little security system,
which
was supposed to check for a negative balance. But, hey, I thought, then I
will just declare the original setBalance() as protected - unfortunately
that is not allowed by the specification.
I would r e a l l y like to hear from anybody who knows a solution to
this.
Any comments would be most welcomed.

Re: HARDWARE FOR J2EE apps
Hi Kevin, Do you create the database in IBConsole ? Because the ibconsole has an bug when creating databases. If so, you probably have to get the newer version of IBConsole : URL : http://www.interbase.com/open/downloads/ib_download.html goto the miscellaneous section (at the bottumn of the page) and download IBConsole - build 308.

Nobody ever said it was cheap! ;) I used to think $25,000 could easily set up a website from front to back, software, hardware, etc..but not even close these days. If you are just starting out, I would use Orion for front-end and ejb-logic tiers in a clustered environment (for developing/testing), with a single server running mySQL or Interbase for the database. Once you get some funding and move beyond the concept phase, you should put a sizeable chunk to invest in co-locating your site and doing the full load-balancing setup. I would estimate a cheap setup with 2 front-end web/servlet servers failed over, 2 ejb servers, and a database cluster will still run around $100,000, to co-lo it..which is probably the best thing to do to make sure its up 24/7.
Re: hi all
Hi myth, Answer on Q1 : The variable out is an static variable, this means that for all instances of System there is only one out variable (all instances of System have a pointer to the same adress in memory on wich out is stored). You can thus call System.out.println() and it will print a message to the screen. Answer to Q2 : When you call getAppletContext you will get an implementation of the AppletContext wich is an actual object. For example if you have a List of Person objects but the persons can be Students, Teachers and SupportingEmpoyees you can create an interface Person wich defines all the methods a person should have. And then let Student, Teacher and SupportingEmployee implement this interface and give each class a different implementation of the methods listed in Person. You can then add different objects(Teachers,Students and SupportingEmployees) to the PersonList class and operate on them with the methods defined in Person.

Hi Jeff, This is because the stack trace is transient. So it is not send over the network (even in local rmi calls). For example if you have a session that call's an entity, and you catch an entity exception in the session, the stack trace doesn't hold state.

Help: Mapping roles to users.
Hi all, I have created an set of Enterprise beans and in the assembly descriptor I have defined a set of roles that have some permissions to run methods ( in ejb-jar.xml). When I deploy the application and the modify orion-ejb-jar.xml to map the roles to different groups in the assembly descriptor and than re-start or re-deploy the application (using orionconsole.jar) orion overwrites the changes I've made in orion-ejb-jar.xml (see below for the deployment descriptors ejb-jar.xml, orion-ejb-jar.xml and orion-ejb-jar.xml after re-starting/re-deploying). Has anybody done this in orion (with ejb 2.0 on orion 1.2.0) ? If so can you sent me the deployment descriptors ? Have I made an error ? (The groups are defined in principals.xml and the role-mappings aren't being overwritten in orion-application.xml). Does the default-method-acces tag in orion-ejb-jar.xml means that all the methods that aren't tied to a method permission in ejb-jar.xml can be called by the group/user and that all the methods that are can't be called ?

Re: Orion and Cloudscape
Hi Ishpal, Thanks for the help. I'll try it out later (already have interbase working with orion and interbase is free(opensource since version 6), so the choice is obvious.) Workaround for your error: Use cloudscape with rmijdbc or cloudconnector so you have to start and shutdown the database server and not orion.

Re: EJB CLIENT
Hi David,
I suppose you have given your application (on the server side)
a name in application.xml.
For instance :
application
display-nameYour_Name/display-name
module ... etc
/application
So then in your jndi.properties file it has to say
java.naming.factory.initial=com.evermind.server.ApplicationClientInitialCont
extFactory
java.naming.provider.url=ormi://localhost/Your_Name {--- The name of
your application}
java.naming.security.principal=admin
Hope this helps,

Re: POSTGRES AND ORION NEWBIE QUESTION
Hi Robert,
Your first question:
Orion emulates the jdbc 2.0 functionality for you if you use
class="com.evermind.sql.ConnectionDataSource"
in data-sources.xml.
So you will get something like this :
data-source
name="postgresql" {link to the database-schemas\postgresql.xml}
class="com.evermind.sql.ConnectionDataSource" {Orion jdbc2.0
emulator}
location="jdbc/postgreDS"
pooled-location="jdbc/postgrePooledDS"
xa-location="jdbc/xa/postgreXADS"
ejb-location="jdbc/postgreEJBDS"
url="jdbc:postgre:yourDB"
connection-driver="" {location (class and package of postgre
driver}
username="your_username"
password="your_password"
/
Your second question:
Don't use getPooledConnection but use getConnection() because Datasource
doesn't have a method
getPooledConnection()
Hope this helps.

Subject: POSTGRES AND ORION NEWBIE QUESTION
Hello,
I just want to make sure I'm on the right track. I am trying to use Orion
and Postgres SQL database together.
Postgres does not have the JDBC 2.0 driver available so I am wondering how
to configure the data-source.xml so ORION will take care of creating a
connection pool for me.
Secondly, I am unsure as to how to which method to call to obtain a
connection from the connection pool from my program. getConnection() or
getPooledConnection()??
Any help would be greatly appreciated..
Thank-you,

Re: application-client.xml, initial context

There are (at least) two factorys provided by orion, the com.evermind.server.ApplicationClientInitialContextFactory and the com.evermind.server.rmi.RMIInitialContextFactory. Up to version 1.1.21 orion automatically put a jndi binding with the beans name specified in the ejb-jar.xml in the context which one got via the RMIInitialContextFactory - a very handy thing, only that it seems not to be covered by any spec... and the newest version does not offer these bindings any more, so that clients relying on RMIInitialContextFactory will fail in the future it seems (i discovered this, because i used this feature, too). Now i'm trying out to use the ApplicationClientInitialContextFactory, and found that documentation about the application-client.xml is rare - not regarding the contents but regarding the place, where to put it. I have for example an application with two modules, which reside _unpacked_ in the application directory, like appname - META-INF - application.xml - module1 - de (classes, this is actual a link to my classes dir) - META-INF - ejb-jar.xml - module2 - de (classes, this is actual a link to my classes dir) - META-INF - ejb-jar.xml each of these modules containing some beans, which are deployed correctly, it seems. I tried to put two application-client.xml files in the META-INFs of the two modules (on the server side), but the ApplicationClientInitialContextFactory still complains, that it can't find the META-INF/application-client.xml. So i suspected, i'll have to put it somewhere on the client side - but where? Or do i have to specify some magic words in the application.xml? I do not want to pack my classes into a client jar, if possible, but leave them unpacked in my CVS tree (within Netbeans/forte) while developing. Could someone please shed some light on the application-client.xml and how it's intended to be used?

Corba clients accessing orion ejb, is it possible?
Hi, I want to know if it is possible to acces a ejb (session bean) running in orion from corba. And if so: 1 How to do it? 2 What orb do you need, i think it is possible with sun jdk1.3 but can you also do it with for instance visibroker for c++ , and if so what version omg corba spec compliant orb do i need( i heard 2.3 but i don't know for sure) ? 3 If it is possible to acces the ejb with c++ do i have to implement the complete javax.ejb package in c++ or does somebody know's about an implementation of this?
