Jboss-seam EJB 3.0 "not bound" error.....

[Brian Oleksa]

I get this error when I try to persist/query data from DB using Jboss seam EJB 3.0 technologies.

Caused by: javax.naming.NameNotFoundException:GenerateChartFromDBDataAction not bound.

Here is my code:

Here is my bean:

package org.jboss.priscus;

import static org.jboss.seam.ScopeType.SESSION;

import java.io.Serializable;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;

@Entity
@Name("databean")
@Scope(SESSION)
@Table(name="sarecord")
public class DataBean implements Serializable {

private long id;

private int time;

private int node;

public DataBean(){}

@Id
public long getId() {
return id;
}

public void setId(long id) {
this.id = id;
}

public int getNode() {
return node;
}

public void setNode(int node) {
this.node = node;
}

public int getTime() {
return time;
}

public void setTime(int time) {
this.time = time;
}

}


Here is my action class

package org.jboss.priscus;

import static org.jboss.seam.ScopeType.SESSION;

import java.util.List;

import javax.ejb.Remove;
import javax.ejb.Stateful;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.jboss.seam.annotations.Create;
import org.jboss.seam.annotations.Destroy;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Out;
import org.jboss.seam.annotations.Scope;

@Stateful
@Name("genchartfromdb")
@Scope(SESSION)
public class GenerateChartFromDBDataAction implements GenerateChartFromDBData {

@In @Out
private DataBean databean;

private List<DataBean> listOfBeans;

@PersistenceContext
private EntityManager em;

public String getSomeData() {

try {

em.persist(databean);
find();
}

catch (Exception e) {
e.printStackTrace();
System.out.println("Problem in the GenerateChartFromDBActionclass....");
}
return "chartoutcomefromdbusingejb";

}

@Create
public void find () {
System.out.println("Find called");
listOfBeans = em.createQuery("select * from public.SARECORD")
.getResultList();
}

@Destroy @Remove
public void destroy() {}

}

Here is my interface

package org.jboss.priscus;

import javax.ejb.Local;

@Local
public interface GenerateChartFromDBData {

public String getSomeData();

}

What could I be possible missing...???

Thanks

Sorry....

I forgot to mention that this is a j2EE web app.

I invoke the action class from my JSF page.

<s:link action="#{genchartfromdb.getSomeData}" value="Get Data" disabled="false"/>

Once I click the above link, I get the NOT BOUND error...

Please check your jndi-pattern declaration, in the Seam example I see the following:
<components xmlns="http://jboss.com/products/seam/components"
xmlns:core="http://jboss.com/products/seam/core">
<core:init jndi-pattern="@jndiPattern@"/>
</components>
