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 Stringname;
public longgetCode() { 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: Deploy war file
Although it describes adding a war and not an ear, this documentation may be of help: http://kb.atlassian.com/content/orionsupport/articles/addwebapp.html Just change application=default to application=Metricas in you default-web-site.xml file.

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
client and server.

Simple WAR file and JSP access?
Created the following directory/file structure | -| || WEB-INF test.jsp | -| || classes web.xml | Servlets | TestServlet.class Created a WAR file and dropped the WAR file in orion_home\applications. Shutdown then started orion. The WAR WAR file was unpacked and created the unpacked directory structure as per the above. The entry: web-module id=WARTest path=../../home/applications/wartest.war / was made in application.xml I can execute the servlet - no problems there. BUT the problem - how to get to the JSP. When it is executed I get a message saying ...\j2ee\home\default-web-app\wartest\test.jsp (The system cannot find the path specified) I am wanting to create a simple WAR file to deploy that may contain only servlets and JSPs and would like to not have to create an EAR file. How do I Access the JSP file?

ORMI with RMIInitialContextFactory fails when server shutdowns
Title: ORMI with RMIInitialContextFactory fails when server shutdowns Hi, I am trying to lookup a ejb running on a remote app server, and I am using the following settings which are posted at the end of the page, PROBLEM : when the remote server is running everything works fine, but when the remote server is down, the application/client fetches the local instance, though I am using the ormi and specifying to connect to the remote server, I face this problem when I work with a same EJB which is deployed in the two different servers and with the same application name. one more thing is I do not want to use the remote=true as the same ejb is needed in the local machine for another applications and pages so I want to know how to stop the server to pick the local instance when the remote server is not running. Properties p = new Properties(); p.put(Context.INITIAL_CONTEXT_FACTORY, com.evermind.server.rmi.RMIInitialContextFactory); p.put(Context.PROVIDER_URL, ormi://208.28.177.97:23791/hello-planet); p.put(Context.SECURITY_PRINCIPAL, admin); p.put(Context.SECURITY_CREDENTIALS, 123); Context ctx = new InitialContext(p); Object obj = ctx.lookup(hello.ejb.Hello); Regards Shravan
