What Do You Put In A Wedding Scroll

Servlet + JDBC

This code is based on what is created automatically by choosing as NetBeans 6.8 Web application project type are reported
:
1. the code of the HTML page launcher (Actually JSP code)
2. the code of a servlet to be placed in the file MHS.java.
Note that: a.
you must install the JDBC driver for ODBC on Windows XP with MySql.
b. SQL syntax is tested on MySQL.
c. need to define a DSN called prova3.
d. prova3 must allow access to a database named test that contains the tables and pet pal whose fields may be inferred from a reading of the SQL string and SQL1.
e. Is done use the "?" that allows you to 'condense' an if then else.
f. In the folder should be added to the package source code (Manzione on top of the file. Java)
g. given the constraints of reporting on a blog some html tags in as arguments to out.print () are not reported, ie the html produced by the servlet should be adjusted




/ / place the file index.jsp


/ / write html
\u0026lt;form action = "http://localhost:8080/Quinta/MHS" method = "GET">;
/ / put at least one submit button






/ / define the package code in your source code package
