How to pass parameter to the method in EJB session bean from Managed Bean

Question

Hi,
I need some guidance in accessing the EJB session bean methods from one of my backing Bean. I use EJB 3.0 Entity Beans and EJB Session Beans. I have to get value from my page and pass it thro the backing bean to the respective EJB session bean. I have no clue of how to do this,
When i click a command link on the page, in its backing bean click method, i am able to get a value and store in a variable under its click action. But from there i am not knowing of how to pass it as a variable to the EJB session bean and hence execute the query(this is where we have to pass the variable as a parameter in its where clause) in the entity bean.
I wanna know how to make a call to the EJB session bean and from there execute the Enitity bean.
Guide me regarding this....
Thanks
ri

Unfortunately dependency injection doesn't work for jsf backing beans, so you have to use a normal jndi lookup to find your session bean. The following example shows you how to find a session bean and call a method:
public void commandButton_actionListener(ActionEvent actionEvent) {
Context ctx;
try {
ctx = new InitialContext();
helloWorldEjb = (HelloWorldEJB)ctx.lookup("HelloWorldEJB");
hello = helloWorldEjb.sayHello(name);
System.out.println(hello);
} catch (NamingException e) {
e.printStackTrace();
}
