✔ JSF mit EJB3 verwursten ...

[acronym]

Hallo Leute ...

ich schreibe ein kleines Testprogramm. Möchte eigentlich nur per knopfdruck Daten in eine DB packe und dann auf einer JSF_JSP-Seite auslesen.
Bekomme javax.ejb.EJBException: java.lang.ClassCastException: [Ljava.lang.String; im JBoss.

JSP

<h:commandButton action="#{navigationBean.getAlleRechner}" id="bitte"></h:commandButton>

BackingBean

public String getAlleRechner() {	
		
			try {				 
				InitialContext ctx = new InitialContext();
				FuellLocal dbfull = (FuellLocal) ctx.
				lookup("FuellBean");
				dbfull.erzeugeEntity();
				ctx.close();								
				
			} catch (NamingException e) {
				e.printStackTrace();
			}		
		return "success";
	}

StatelessBean

public void erzeugeEntity (){
		String[] string1 = {"a","b","c"};
		ControlEntity2 entity = new ControlEntity2();
		entity.setRechnername("Bla1");
		entity.setNewProcesses(string1);
		entity.setPolicy("stop");
		entity.setTimestamp(TimeHandler.getTime());
		
		String[] string2 = {"d","e","f"};
		ControlEntity2 entity2 = new ControlEntity2();
		entity2.setRechnername("Bla2");
		entity2.setNewProcesses(string2);
		entity2.setPolicy("stop");
		entity2.setTimestamp(TimeHandler.getTime());
		
		em.persist(entity);
		em.persist(entity2);
		em.close();
		
	}

Fehlermeldung JBoss

Es wäre eine schöne Sache, wenn da jemand einen Tip hätte, falls ich mich dumm anstelle sagt es bitte durch die Blume

...
der Fehler lag an der Methode im Stateless...weiß aber nicht wirklich warum.

jetzt habe ich

javax.servlet.ServletException: #{navigationBean.getAlleRechner}: javax.ejb.EJBException: java.lang.IllegalStateException: Illegal to call this method from injected, managed EntityManager
