Compilation Error

[Ravissant Markenday]

hi everyone!

im getting this error while compiling a servlet:

SessionLifeCycleServlet.java:88: setAttribute(java.lang.String,java.lang.Object
in javax.servlet.http.HttpSession cannot be applied to (java.lang.String)
session.setAttribute(fname);
^

Could anyone please tell me what it means and what i can do to fix it?

Thanks in advance,
Ravissant Markenday

I think you're missing a parameter. You have to provide a name/value pair to the setAttribute method.

session.setAttribute("First Name", fname);

Here's a tutorial on using the HttpSession object, along with some sample code:

Any setAttribute method will accept two parameters. both are of type Object.

But you are passing only one parameter. Make it two(both should of type Object).

Not entirely true.
The setAttribute method does take two arguments but the first is java.lang.String.
