call ejb from war via JNDI problem
Hi,
I met a problem when I call ejb in a war.
Firstly, I create a EJB project, and deploy it to JBoss AS7.1.1,it's successful
code:
1)UsersDao.java
@Stateless
@Remote(UsersDaoRemote.class)
public class UsersDao implements UsersDaoRemote{
@PersistenceContext //这里应用EJB3的IOC,得到EntityManager
private EntityManager em; //相当于Hibernate的Session
/**
* Default constructor.
*/
public UsersDao() {
// TODO Auto-generated constructor stub
}
public String getForUsername(String username)
{
xxxx
}
2)UsersDaoRemote.java
@Remote
public interface UsersDaoRemote{
public String getForUsername(String username);
}
secondly, I create a dynamic web project, and deploy it to JBossAs7.1.1 server successful
code:
public void loginIn() throws NamingException
{
InitialContext ctx = new InitialContext();
//String ejbname = "ejb:sms_ejb/UsersDao!com.hxchn.sms.UsersDaoRemote";
String ejbname = "java:global/sms_ejb/UsersDao!com.hxchn.sms.UsersDaoRemote";
UsersDaoRemote usersDaoRemote=(UsersDaoRemote)ctx.lookup(ejbname);
}
but when the jsf call the loginIn function it failed, the log below
