????Why can?t I lookup the complex object in JBOSS? ????
I have code one small program. It can run successfully in main() method. Then I want to access it through servlet/jsp, but it always throw the Exception:
javax.naming.CommunicationException [Root exception is java.net.MalformedURLException: no protocol: Files/Apache]
the server which I use is ?jboss-4.0.3SP1?
the BEAN which I define is :
package com.mycompany;
import java.io.Serializable;
import java.rmi.Remote;
import java.util.Hashtable;
import javax.naming.InitialContext;
public class MyBean implements Serializable,Remote{
private static String foo ="";
private static int bar=100000;
public String getFoo() {
return (this.foo);
}
public void setFoo(String foo) {
this.foo = foo;
}
public int getBar() {
return (this.bar);
}
public void setBar(int bar) {
this.bar = bar;
}
public static void main(String[] args) {
try {
Hashtable ht = new Hashtable();
ht.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
ht.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
ht.put("java.naming.provider.url", "jnp://localhost:1099");
InitialContext ic = new InitialContext(ht);
ic.bind("jndiname", "----hello--jndi----");
String obj = (String) ic.lookup("jndiname");
System.out.println("-----------------212-the result of lookup is--:" + obj+"");
ic.unbind("jndiname");
MyBean mybean=new MyBean();
ic.bind("jndiname2", mybean);
MyBean bean=(MyBean)ic.lookup("jndiname2");
System.out.println("------11------the result of lookup is--:" + bean.getBar()+"");
ic.unbind("jndiname2");
} catch (Exception e) {
e.printStackTrace();
}
}
}
It can run very well in this main() method, but can not run in the servlet, the servlet code is:
try {
Hashtable ht = new Hashtable();
ht.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
ht.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
ht.put("java.naming.provider.url", "jnp://localhost:1099");
InitialContext ic = new InitialContext(ht);
ic.bind("jndiname", "----hello--jndi----");
String obj = (String) ic.lookup("jndiname");
out.println("-----------------212-the result of lookup is--:" + obj+"");
ic.unbind("jndiname");
MyBean mybean=new MyBean();
ic.bind("jndiname2", mybean);
MyBean bean=(MyBean)ic.lookup("jndiname2");
out.println("------11------the result of lookup is--:" + bean.getBar()+"");
ic.unbind("jndiname2");
} catch (Exception e) {
e.printStackTrace();
}
