Servlet client unable to access SessionBean method

[bea]

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(" Cliente EJB ");
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 :S

Any help will be welcome

You have to declare Libro sal, outside the try,catch block. Otherwise it's not visible to the statements outside the block.

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

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


sal.saluda();
out.println("");
out.close();


Thanks,
Kalyan.
