can't figure out namingException

I get the error shown below. It is repeated twice more for lines 27 and 28. I use these exact same three lines of code in various other places in my jsp pages. The only difference is these particular lines are include in a subroutine (<%! ... %>) whereas the others are in-line in the jsp page. What is my problem??!! I'm so confused!

An error occurred at line: 26 in the jsp file: /include/email.inc
Unhandled exception type NamingException
23:    
24:     if ((from == null) || (from.length() == 0))
25:     {
26:           Context ctx = new javax.naming.InitialContext();
27:           Context env = (Context) ctx.lookup("java:comp/env");
28:       replyAddr = (String) env.lookup("webUser");
29:

you need to put it ina  try/catch block

try
{
           Context ctx = new javax.naming.InitialContext();
           Context env = (Context) ctx.lookup("java:comp/env");
       replyAddr = (String) env.lookup("webUser");
}
catch (NamingException ex)
{
   // handle exception
}

So, explain why I need a try/catch block in a subroutine, but not in the "main" program? Is there an implied try/catch on the main page?

yes. though its not really implied. the generated method is defined to handle the exception.
