You may use the constructor to set values at point of instantiation. However, an object may have many attributes that 1) you may not know at the point of instantiating or 2) may need to be changed after instantiating.
For this you need setters.

Hi Eric,

This is expected.
If you type javac -help you will see that -d is to specify the directory of the generated class files. And since "src\com\example\web\BeerSelect.java" is not a directory, it is stating that.

Cheers,
Code On!

Hi Nolan,

Firstly, - do as Greg has mentioned.

Then you need to figure out if the username and password is correct or not. For this you will need to access your Database, and query for the user entered username and password. I cannot give you any more detail here before you mention what technology you will be using for DB access.

Another thing is you mention calling getPassword and printing on the screen. This is not a done thing in any app - ever!

for the final step you have mentioned you just need a loop that would return when login is successful. Something like this (note I have not used your KeyboardReader class as that must be a proprietary thing you are using)

Hey Cathy,

Not sure what you are trying to do with the 'Arithmetic ' class, but in order to show a list of results in your JTextArea you need to create a string containing the list before you set it to it.

Try the following

Do you see javac in your jdk1.6.0_30/bin ? How are you trying to compile? Command Line?
Please post more details on your execution environment and any error messages.

Yep tomcat does get accessed according to the log, it doesnt log anything about the completion of the task. (Not sure if it's supposed to)

INFO: Undeploying context [/simple]

I have added the following target to my build.xml, and when invoked, it results with the success message (below)

<target name="undeploy">
<undeploy url="${tomcat.manager}"
username="${tomcat.username}"
password="${tomcat.password}"
path="/${app.name}" />
</target>

--------------------------------------------------------------
undeploy:
[undeploy] OK - Undeployed application at context path /simple

BUILD SUCCESSFUL
Total time: 0 seconds
--------------------------------------------------------------------

However, the app doesnt get properly undeployed, as it still shows as 'running' in the tomcat manager.

Any ideas?
