Servlet client unable to access SessionBean method

[Beatriz Campo González]

Hello,
I've deployed a simple SessionBean with jndi name="Libro"
I've written a servlet, the client of the EJB, which tries to access to "saluda()", the method of the EJB. I get the following error when I compile the client:

cannot find symbol
symbol: variable sal
location: myServlet
sal.saluda();

Here is the code for the servlet:

res.setContentType("text/html");
PrintWriter out = res.getWriter();

out.println("");
out.println("");
out.println("");

try
{
Context contexto = new InitialContext();
Object ref = contexto.lookup("Libro");
LibroHome home =
(LibroHome) PortableRemoteObject.narrow(ref,Beans.LibroHome.class);
Libro sal = home.create();
}

catch (Exception e)
{
e.printStackTrace();
}


sal.saluda();//<---------HERE IS THE ERROR
out.println("");
out.close();

The "saluda()" method only prints a greeting, it's quite simple.

I don't know what is wrong? maybe the package?? I'm really confused

Any help will be welcome?:|

try blocks define scopes in java.

so:

try {
String foo = "Rob":
} catch () ...

foo = "me";

will give you a compilation error.


Either

String foo = "Rob";

try {
foo = "me";
} catch () ...

foo = "you";

is correct:

or

try {
String foo = "Rob";
foo = "you";
} catch ()...

-- Rob
