我正在使用Jboss-6.1.0。我正在尝试创建一个EJB来打印Hello world。我有三个classess。 1。
package remoteif;
import java.rmi.*;
import javax.ejb.*;
public interface HelloWorld extends EJBObject{
public String sayHello() throws RemoteException;
}
2
package homeif;
import remoteif.HelloWorld;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
import java.rmi.RemoteException;
public interface HelloWorldHome extends EJBHome {
public HelloWorld create() throws
CreateException, RemoteException;
}
和 3。 package beanimpl;
import remoteif.HelloWorld;
import javax.ejb.*;
import java.rmi.RemoteException;
public class HelloWorldBean implements SessionBean {
// Methods of Remote interface
public String sayHello() {
return "Hello, world !";
}
// Methods of Home interface
public void ejbCreate() {}
protected SessionContext ctx;
public void setSessionContext(SessionContext ctx) {
this.ctx = ctx;
}
@Override
public void ejbRemove() throws EJBException, RemoteException {
//To change body of implemented methods use File | Settings | File Templates.
}
@Override
public void ejbActivate() throws EJBException, RemoteException {
//To change body of implemented methods use File | Settings | File Templates.
}
@Override
public void ejbPassivate() throws EJBException, RemoteException {
//To change body of implemented methods use File | Settings | File Templates.
}
}
我在META-INF目录中使用两个xml文件ejb-jat.xml＆amp; jonas-ejb-jar.xml。我已创建此应用程序的jar文件（包括类文件和xml文件）和包含此jar文件和application.xml文件的ear文件。我已将其复制到JBOSS服务器中。但是当我启动服务器时，我收到以下错误。

我该怎么做才能清除此错误？
