Cannot run EE client

[mirik]

Hi all.

I created a simple stateless EE EJB3 and its client.
I succeed the execute the client with appclient:
C:\j2ee-projects>appclient -client testclient.jar

But I have a problem when running it with jar name:
C:\j2ee-projects>java -jar testclient.jar
Exception in thread "main" java.lang.NullPointerException
at testclient.main(testclient.java:9)

And also when running it with class name:
C:\j2ee-projects>java -cp chapter1-ejb.jar;testbeans.jar testclient
Exception in thread "main" java.lang.NoClassDefFoundError: testclient
Caused by: java.lang.ClassNotFoundException: testclient
at java.net.URLClassLoader$1.run(URLClassLoader.java: 200)
at java.security.AccessController.doPrivileged(Native Method)

at java.lang.ClassLoader.loadClass(ClassLoader.java:2 52)
at java.lang.ClassLoader.loadClassInternal(ClassLoade r.java:320)
Could not find the main class: testclient. Program will exit.


This is the manifest file inside testclient.jar:
Manifest-Version: 1.0
Class-Path: chapter1-ejb.jar testbeans.jar
Main-Class: testclient

Could someone tell what is the problem there?

When you run it as a jar file, there is something required at line 9 of testclient which you are not providing and causing the null pointer.
When you run it as a class, add the folder containing the testclient.class to the classpath as well. If it is the current directory then add dot, ie .

P.S Better put your classes in packages and name then according to Java naming conventions.

Thanks for response r035198x.

Here is the correct answer:
The @EJB annotation can be used only inside another EE container or by appclient.
In order to call it from POJO utility class you should write:
try{
Context ctx = new InitialContext();
testint cls = (testint)ctx.lookup("testint");
}catch(Exception ex) { ex.printStackTrace(); }
