Hi,
This is not actually solved yet. When I try to compile my bean class, I get
an error that says:
HelloBean.java:7: cannot find symbol
symbol: class Resource
@Resource(name = "PostgreSQL Database", type = "javax.sql.DataSource")
^
1 error
My source files look like this
// Remote interface
import javax.ejb.Remote;
import java.util.List;
@Remote
public interface Hello
{
public String sayHello();
}
// Bean class
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.*;
@Resource(name = "PostgreSQL Database", type = "javax.sql.DataSource")
@Stateless
public class HelloBean implements Hello
{
public String sayHello()
{
return "Hello from EJB world!";
}
}
There's no database operations yet, because I'm first trying to get it
through the compiler with the Resource annotation. The PersistenceContext
annotation does not cause any errors.
My classpath is
.:/opt/apache-tomcat-6.0.10/lib/servlet-api.jar:
/opt/apache-tomcat-6.0.10/lib/jsp-api.jar:
/usr/share/java/postgresql-jdbc3-8.1.jar:/opt/junit/junit-4.4.jar:
/opt/openejb-3.0-beta-1/lib/geronimo-ejb_3.0_spec-1.0.jar:
/opt/openejb-3.0-beta-1/lib/openejb-client-3.0-beta-1.jar:
/opt/openejb-3.0-beta-1/lib/geronimo-jpa_3.0_spec-1.1.jar
Is there something missing?
Java is version 1.5.0_08.
