I am using Netbeans and am experimenting with EJBs.

I have two projects (2 separate applications)

1- A J2EE Project called EnterpriseApp

2- A standard J2SE Project called Test

Now Here is what I did - in EnterpriseApp I generated a stateless EJB called TestEJB with both local and remote interfaces. For the remote project selection I selected the Test App. In short the bean code looks like this


And in the J2SE client Project here is my main class through which i am trying to access the bean



This is the contents of JNDI.properties file

java.naming.factory.initial = com.sun.enterprise.naming.SerialInitContextFactory
java.naming.factory.url.pkgs = com.sun.enterprise.naming
java.naming.factory.state = com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl
#optional. Defaults to localhost. Only needed if web server is running
#on a different host than the appserver
org.omg.CORBA.ORBInitialHost = localhost
#optional. Defaults to 3700. Only needed if target orb port is not 3700.
org.omg.CORBA.ORBInitialPort = 3700

And I get this error at
TestEjbRemote testEJB = (TestEjbRemote) ctx.lookup("stateless.TestEjbRemote");




Any suggestions on how i may resolve this issue ?

I ran my first struts2 example from http://www.vaannila.com/struts-2/struts-2-example/object-backed-java-beans-example-1.html which just displayed a form and echoed the contents back and I had a pretty basic question , I dont see the program attaching anything to the request object at the same time I read that using httpRequest object in struts2 is not a good practice.What I want to know is how is the object being attached and to what is it being attached to since its being accessed by the result page?


The struts.xml is


The form submitted calls the UserAction which is



and the echo form is

I am completely new to struts and I am trying to integrate it into my project.

I created an action called LoginAction and inserted it into the web.xml as follows:


I then placed struts-config.xml next to my web.xml with the following content


But when I submit a form with action="login.do"
I get the following:

Any suggestions what might be going wrong ?

JSP

The behavior of the above code regarding mixing of CSS with generated HTML is confusing me. According to my understanding no matter what condition is accepted (ConditionA or ConditionB) the generated HTML in both cases should be inside the class "msg" however I am getting different results. ConditionB only gets enclosed in the class msg whereas condition A in which a table is generated is placed below the class "msg" (i.e the class is closed and then the table starts) Could anyone tell me whats going on?

The following bind command works if the source files are next to bind.xml

java -jar C:\jibx\lib\jibx-bind.jar example24\binding.xml

How would i make the above command work if the generated java files were created say in a folder called "example" thus having a "package example" on top of them ?
Hi is there a way by which i can generate a random no between a specific range.
I read that the class allows you to generate no between 0-n ie.(0-65) what if i want to generate random nos between 55-65 ??
