Problems Scanning classpath in the embedded-tutorial/simple-
Hi all and Hi Bill,
since yesterday I try to solve the problem in a standalone application. First I do not use JBoss-4.0.4RC1 AS to run my application. I use JBoss-EJB-3.0_Embeddable_ALPHA_5 and thus my error in the console of eclipse look like this:
DEBUG 22-03 08:45:57,203 (KernelFactory.java:assembleNewKernel:86) -Starting JBoss Kernel construction...

-----------------------
In the Classpath i have
- resources/META-INF/persistence.xml
and it looks like this
<?xml version="1.0" encoding="UTF-8"?>
<persistence-unit name="custdb">
<jta-data-source>java:/DefaultDS</jta-data-source>
</persistence-unit>
- and all config-files in conf/
+ embedded-jboss-beans.xml
+ jboss-jms-beans.xml
+ ejb3-interceptors-aop.xml
+ default.persistence.properties
+ log4j.xml
and then thus my pojos, bean and interfaces look like this
- Customer.java
@Entity
@Table (name="CUSTOMER_")
public class Customer {
private int id;
private String name;
public Customer(){}
@Id @GeneratedValue(strategy=GenerationType.AUTO)
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
- CustomerDAOBean.java
@Stateless
public class CustomerDAOBean implements CustomerDAOLocal, CustomerDAORemote {
@PersistenceContext (unitName="custdb")
private EntityManager em;
public int createCustomer(String name) {
Customer cust = new Customer();
cust.setName(name);
em.persist(cust);
return cust.getId();
}
public Customer findCustomer(int id) {
return em.find(Customer.class, id);
}
}
- Local & Remote Interfaces
@Local
public interface CustomerDAOLocal {
int createCustomer(String name);
Customer findCustomer(int id);
}
@Remote
public interface CustomerDAORemote {
int createCustomer(String name);
Customer findCustomer(int id);
}
- Main.java
public class Main {
public static void main(String[] args) throws Exception
{
EJB3StandaloneBootstrap.boot(null);
EJB3StandaloneBootstrap.scanClasspath();
InitialContext ctx = getInitialContext();
CustomerDAOLocal local = (CustomerDAOLocal)ctx.lookup("CustomerDAOBean/local");
CustomerDAORemote remote = (CustomerDAORemote)ctx.lookup("CustomerDAOBean/remote");
System.out.println("----------------------------------------------------------");
System.out.println("This test scans the System Property java.class.path for all annotated EJB3 classes");
System.out.print(" ");
int id = local.createCustomer("Gavin");
Customer cust = local.findCustomer(id);
System.out.println("Successfully created and found Gavin from @Local interface");
id = remote.createCustomer("Emmanuel");
cust = remote.findCustomer(id);
System.out.println("Successfully created and found Emmanuel from @Remote interface");
System.out.println("----------------------------------------------------------");
}
public static InitialContext getInitialContext() throws Exception
{
Hashtable props = getInitialContextProperties();
return new InitialContext(props);
}
private static Hashtable getInitialContextProperties()
{
Hashtable props = new Hashtable();
props.put("java.naming.factory.initial", "org.jnp.interfaces.LocalOnlyContextFactory");
props.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
return props;
}
}
If somebody have or know the solution of this issue please suggestion or send maill because I do not know where is the probleme in
my configs or in my classes
Thanks
