RE: getClass().getClassLoader().getResource(fileName) problem
I Believe the Orion directory is the root for File access.
Or at least it was for me as I started the server up from there.
Hope this helps.

Hi,
I tried to open a property file from within my
custom UserManager program, however, Orion was unable
to find my file. I just don't know where should I put
my property file so it can be located by the following
command:
props_ = new Properties();
try {
URL aURL =
getClass().getClassLoader().getResource(fileName);
InputStream in = (InputStream)aURL.openStream();
props_.load(in);
Thanks a lot.

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:
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.

This might seem like a stupid suggestion but try changing the order you pass the parameters in so the number of records you are retrieving is first and the id is second.

RE: OC4J datasource / server crash problem
When you get the connection you will need to put it in a try and catch.
At the end use a finally to return the connection.
e.g.
try
{
Connection c = YourClass.getConnection();
}
catch (SQLException ex)
{
//Do something with the exception
}
finally
{
YourClass.returnJDBCConnection(c);

Subject: OC4J datasource / server crash problem
Hi,
I am currently part of a project developing a servlet/stateless EJB
solution to be run on the Orion platform. We are experiencing some
problems using our datasource connection to our Oracle 9i database. The
server will on occasion leak connections, which eventually results in
both the Orion server and the database crashing.
I include our data-sources.xml file to indicate how things are set up.
We currently only use the ejb-location for database access from our EJBs
and servlets.
?xml version=1.0?

Our code for retrieval of the database connection:
private static Connection getConnection( String provider, String
prefix )
throws InitializerException {
try {
if (ic==null) ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(prefix+provider);
Connection conn = ds.getConnection();
conn.setAutoCommit(false);
return conn;
} catch (NamingException cfe) {
throw new InitializerException(Unable to lookup Datasource );
} catch (SQLException se) {
throw new InitializerException(Unable to get DB connection);
}
}
Returning the connection:
public static void returnJDBCConnection(Connection conn)
throws InitializerException {
try {
conn.close();
} catch (SQLException se) {
throw new InitializerException(Unable to return DB connection);
}
}
The exception we are getting is:

RE: Debugging with Orion/Kawa Pro 5.0
I remember seeing something about orion not working in Kawa Enterprise. We had a problem where if you install Enterprise the uninstalled. Then installed Kawa Pro you could not run orion from inside. Can't remember if this was orion but there where issues with changing Kawa'a (if think kawa released a patch to fix it). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of DENNIS STRAIGHT Sent: 07 September 2001 06:48 To: Orion-Interest Subject: Debugging with Orion/Kawa Pro 5.0 I appreciate Dave Smith's write-up on debugging with Orion/Kawa but, unfortunately, I think I'm missing something and need more info. Here is what I did: Created a new project with all of my java files (servlets, EJBs, and regular Java). Added Orion.jar to the Kawa classpath. Set the class to run to com.evermind.server.ApplicationServer Made sure JVMDI was turned off Added breakpoints, hit F5 and... nothing happens, I don't see orion starting in Kawa's output pane... I don't see anything. Next, I open a web browser set to a localhost url that works fine when I run Orion from DOS and, of course, the page is not found. Because Orion hasn't started, I'm sure. Does anybody know what I'm doing wrong (Why Kawa isn't starting Orion)? Below I'll print Dave Smith's debugging tips, if anybody can tell me anything that is missing I would greatly appreciate it. Thanks, Dennis Dave Smith adds: Debugging with Orion and Kawa is a pleasure. Get Kawa Pro (not the enterprise version) from Tek-Tools and install it. Configure your JDK as required when you first run Kawa. (Note that Kawa is a Win32 application, which is one of the reasons I don't use it.) Create a new project for your servlets or EJBs. Add orion.jar, any additional jars required by the application, and the deployed class directory (i.e., c:\applications\myApp\myApp-web\WEB-INF\classes or c:\applications\myApp\myApp-ejb, or both). From the Project/Interpreter menu, set the Java class to run to com.evermind.server.ApplicationServer and remember to tell it to use this class (as this image, given me by Chris Miller, shows). Turn off JVMDI debugger from the Customize/Options/Advanced Paths form, which is for performance only and is not vital. Add the breakpoints to your servlets and/or EJBs. F5 starts debugging, and Dave adds to Relax, sit back and enjoy the ride. The speed kills NetBeans dead. Also from Dave: For a real screamer, use Jikes: Customize/Options/Advanced Paths/Compiler = D:\jikes\jikes.exe +E And set Orion to use jikes from $ORION/server.xml.

RE: External EJB Client
You need the application-client.xml file on the client machine.
If you place it in a META-INF directory below the location where your
program is running it should be able to find it.
In the application-client.xml you need to define the resource you are trying
to look up.
If you get it working could you post the step you went through as i have
gone through the examples proved with orion and i still can not get a client
to use an ejb.
Hope this helps.
