}

 
Running Methods/Accessing View
a. Edit Web Pages/index.xhtml
b. Add xmlns:f=http://java.sun.com/jsf/core
c.














Debugging
1. Helpful to run server from console using glassfish\bin\startserv so you can see stacktraces in terminal window.
Database
Example of how to create a table with autoincremented primary key
CREATE TABLE film (
filmId INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(255) ,
description VARCHAR(1000)
);

What to plan before starting development on a project?

[someone asked this on Programmers.stackexchange.com - my response]

Most important thing to do: review the specs, interact with customer to get more refined specs.

The requirements are undoubtedly incomplete, vague, or incorrect. The biggest waste of time is doing the wrong thing. Customers are not professional software engineeers, and cannot be expected to be good at developing a good set of requirements.

So, you should review the specs, interview the customer and find out if this is what he/she really needs and wants, and can afford, etc.

Develop test/use cases and review with customer. If a requirement isn't testable, throw it out.

Develop the design and make sure if all the pieces function correctly that it would in theory do what you need.

Develop an architecture prototype that tests all of the technology to be used in every layer but ignore functionality. You are testing the architecture, not the functional specification. Having the wrong architecture will mean you have to rewrite everything, so getting the right architecture is important. Make sure it can meet your requiremenets for speed, efficiency, security, etc.

How to delete a windows service

1. Run Regedit or Regedt32

2. Find the registry entry "HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services"

3. Look for the service there and delete it. You can look at the keys to know what files the service was using and delete them as well (if necessary).

Glassfish no free port available port value out of range

You may get this error when trying to start the Glassfish server. I believe this occurs because it's trying to use a port already in use.

My glassfish was set up with default ports 8080, and I had a Default Web Site and Team Foundation server running using port 8080. When I shut these off, this error disppeared.

When I have time I'll just change the ports.

Kamikaze Java

Sun's Java initiative reminds me of the Kamikaze in WWII. A gutsy move against an overwhelmingly powerful enemy, but they had to know its close to the end when they're that desperate.

Zune - No installation Media

This fix worked for me
