I have tried to create this jsp page. I select from a HTML page a file. From
the page HTML I call the page JSP to show the path of the file. The path is
holden in a database. I have registered the database with ODBC.
When I try to start this page IE returns to me an error.
Here there are the first.htm e the first.jsp, where are the errors?
Thanks.

String final;

final is a keyword, give it another name.

I have modified the name of the string but now there's another error

Try setting a real charset, like utf-8 for example.
