Prepare file
Required software: JDK1.3 (for win), J2EE_1_2_1_SDK, JBoss2.0 (www.jboss.org)
Required documents: J2EE_1_2_1_SDK_DOC, DevGuide1_2_1
2. Prepare the environment
Install JDK1.3 (support JBoss), check the environment variables after installation, you can compile a small program to try it.
Install jboss2.0, run bin / run.bat after completion. JNDI port is 1099, the web port is 8080, you can try it with the browser, 1099 port will return a garbled, 8080 port returns empty.
3. Compile and package
According to the compilation example of the Getting Started in JavaTM 2 Enterprise Edition Developer's Guide (V1.2.1), CONVERTERAPP.EAR is generated with Deploy Tool package.
EjB-JAR-IC.jar from Jar -xvf Convertrapp.ear This is the three files and tools related to BEA-related files and tools to generate meta-info / *. XML files (so-called deployment descriptor).
Then run the jboss's deploy Tool Open EJB-JAR-IC.JAR, set JNDI Name to MyConverter. Then save. (This tool automatically generates JBoss Deployment Descriptor)
On the jboss / deploy directory, JBOSS will automatically release the bean in the JBoss / Deploy directory.
4. Run the client program test
Modify ConverterClient.java according to JBoss teaching documentation
Import javax.naming. *;
Import java.util.hashtable;
Import javax.rmi.portableremoteObject;
Import java.util.properties;
Import java.io.fileinputstream;
Import javax.rmi.portableremoteObject;
Import converter;
Import converterhome;
Public class convertern {
Public static void main (String [] args) {
Try {
Properties PROPS = New Properties ();
Properties sysprops = system.getproperties ();
Try {
ProPs.Load (New FileInputStream ("Test.properties"));
sysprops.putall (prOPs);
} Catch (Exception E)
{
System.err.Println ("Can't Read` Test.proprties');
System.exit (-1);
}
System.SetProperties (sysprops);
Context initial = new initialcontext ();
Object objref = initial.lookup ("myconverter");
Converterhome Home =
(Converterhome) PortableRemoteObject.narrow (Objref,
Converterhome.class;
Converter currencyconverter = home.create ();
Double amount = currencyconverter.dollartoyen (200.00);
System.out.println (String.Valueof (Amount)); Amount = CurrencyConverter.yentoeuro (200.00);
System.out.println (String.Valueof (Amount));
} catch (exception ex) {
System.err.Println ("Caught An Unexpected Exception!");
EX.PrintStackTrace ();
}
}
}
Test.properties file content is as follows
Java.naming.Factory.initial = org.jnp.interfaces.namingcontextFactory java.naming.provider.URL = xxx.xxx.xxx.xxx: 1099 (IP on the machine where jboss is located)
Then run CompileClient.bat and TestClient.bat, you can enjoy the joy of success.
