The application remains the same regardless of the way it is accessed. Local or remote access is just that: - an interface to an application. Your core application remains the same regardless of the view. The business objects should not be coded any differently.

I propose we leave different views in, gives an opportunity to work on some new technologies.

I made some modifications to the UML. I used DIA (Diagram editor supporting windows, mac and Linux) - http://dia-installer.de/. Change the extension of the png file to dia and use DIA to open the file. CSR- Customer Service Representative (Cashier)

Programming / Re: Help On How To Run A Servlet Http Program by wassolldas: 4:41pm On Jul 09, 2011
you need a container to deploy your servlet. Search for tomcat. Servlet is JEE/J2EE technology, so you should have some understanding of that.

Guys who have not done much documentation should take a stab at this. Creating documentation is now expected of developers.

Programming / Re: Connecting To A Remote Database(jdbc) by wassolldas: 3:41pm On Jul 04, 2011
proxy is probably less complicated. Don't know if your host supports java. To expose the interface through RMI, your host has to support java.
Programming / Re: Connecting To A Remote Database(jdbc) by wassolldas: 3:34pm On Jul 04, 2011
Just an idea, never had to do this before,

Use RMI to make access to the database available from your server. You need a port to use for the RMI registry.
Use RMI to obtain the access from your local machine,

Programming / Re: Urgent Help With Directories In Java. by wassolldas: 5:41pm On Jun 27, 2011
API: http://www.oracle.com/technetwork/java/javase/documentation/api-jsp-136079.html

For java 6 at http://download.oracle.com/javase/6/docs/api/
java.io.File
- isDirectory method tells you if the path is a directory or not.
- isFile method tells you if the path is a file.

- list method - Returns an array of strings naming the files and directories in the directory denoted by this abstract pathname.
- listFiles - Returns an array of abstract pathnames denoting the files in the directory denoted by this abstract pathname.


Refer to the API and write the code to do what you need.

The implementation of containsValue in HashMap:


public boolean containsValue(Object value) {
if (value == null)
return containsNullValue();

Entry[] tab = table;
for (int i = 0; i < tab.length ; i++)
for (Entry e = tab[i] ; e != null ; e = e.next)
if (value.equals(e.value))
return true;
return false;
}
Programming / Re: Java Cafe by wassolldas: 6:15pm On Jun 19, 2011
Does FileSys define an equals method? It should override

public boolean equals(Object obj) {
return (this == obj);
}


from Object

Programming / Re: Java Cafe by wassolldas: 6:00pm On Jun 19, 2011
you should use containsValue, and your check should be on the object not the name of the file
Programming / Re: Java Cafe by wassolldas: 5:50pm On Jun 19, 2011
Your code not not compile. A HashMap does not allow duplicate keys. To check if a value exists in a HashMap, use the method - HashMap.containsValue(Object value). Iterating through the set of keys is a performance killer.


containsValue

public boolean containsValue(Object value)

Returns true if this map maps one or more keys to the specified value.

Refer to the java API for more information.
Programming / Re: Critical Question For Programmer Gurus by wassolldas: 3:52pm On Jun 08, 2011
Remember that all entries on the path variable should be separated by ';' - So add C:\Sun\SDK\jdk\bin; in front of your path variable or ;C:\Sun\SDK\jdk\bin at the back.
Programming / Re: Critical Question For Programmer Gurus by wassolldas: 3:22am On Jun 08, 2011
** You should make sure the path you installed the jdk is correct as pointed out by omo_to_dun,

You have some invalid characters in your path. You pasted the following: C:\Program files/Java/jdk1.5.0/bin;"C:/Program Files/PC Connectivity Solution/;C:/Program Files/Common Files/Microsft Shared/Windows Live; C:/windows/system32;C:/windows;C:/System32/Wbem;C:/windows/System32/WindowsPowerShell/v1.0/;c:/Program Files/Common Files/Roxio Shared/DLLShrea/;c:/Program Files/Common Files/Roxio Shared/10.0/DLLShared/;C:/Program Files/Common Files/Ulead Systems/MPEG; "C:/Program Files/Java/jdk1.5.0/bin;".

But you should remove the quotes, so that it becomes the following:
C:\Program files/Java/jdk1.5.0/bin;C:/Program Files/PC Connectivity Solution/;C:/Program Files/Common Files/Microsft Shared/Windows Live; C:/windows/system32;C:/windows;C:/System32/Wbem;C:/windows/System32/WindowsPowerShell/v1.0/;c:/Program Files/Common Files/Roxio Shared/DLLShrea/;c:/Program Files/Common Files/Roxio Shared/10.0/DLLShared/;C:/Program Files/Common Files/Ulead Systems/MPEG;C:/Program Files/Java/jdk1.5.0/bin

Close all open command prompt windows after you change the path and open a new one to test. On older versions of Windows OS, autoexec.bat used to be executed to register changes to the path but I don't think that is needed for newer versions of the OS.

Windows Operating Systems use the forward slash (\), but backward slash (/) should work fine as well.

Change the all the / characters to \ if the java command still does not work.

Programming / Re: Abstract, Interface And Adapter Classes by wassolldas: 2:54pm On May 16, 2011
An Adapter is a design pattern. The simplest example I can think of at the moment is - Consider an electric outlet with the three outputs type used in Nigeria. if you buy an electrical component from a country that has a different input format from that used in Nigeria, you will need an Adapter to make sure the new device works with the existing outlet.

Similarly if you have an existing library that provides a correctly working implementation and you get a new class or library that needs to work together with what you have on ground, the Adapter design pattern comes in handy to provide an interface between the two libraries or classes.

ExistingClass - existingMethods  communicates with NewClass - newMethods by using an Adapter class. The Adapter class takes the method of the existing classes and modifies the output into the format understood by the new class.
Programming / Re: Post Your Ocpjp (scjp) Questions Here by wassolldas: 2:42pm On May 16, 2011
A class NEED not implement all the methods of an interface that it implements - A class that does not implement all the methods of an interface that it implements MUST be declared abstract. Choosing to use an interface or an abstract class is largely down to design reasons.

The following example is a bit simplistic but it is what I could come up with on the fly -

For example, let's say we have an abstract class Person - having the implemented methods - getName, getAge, getHeight etc. Logical subclasses could be Parent and Child.
Another abstract class Craft having the implemented methods -  start(), stop(), idle(). Logical subclasses could be Airplane, Submarine, Helicopter.

And we have an interface called Moveable - with the contract move(), increaseSpeed()

The classes Person and Craft could both implement Moveable and provide separate implementations. But Person and Craft do not follow a logical inheritance path.

I hope this helps to some extent.
Programming / Re: Abstract, Interface And Adapter Classes by wassolldas: 2:22pm On May 16, 2011
An interface is a contract that a class pledges to fulfill. A specification of methods that any implementing class promises to provide functionality for.
Programming / Re: why the unexpected $end by wassolldas: 4:39am On Jan 05, 2011
first thing: Don't ever write code like this! Even when learning, it breeds bad habits. Separate your business logic, user interface and data access codes. Put the JavaScript code in a different file.

Okay,
You have to recognize two things in the following order.

1. PHP code is parsed server side and then ,

2. JavaScript is executed on the client side (in the browser).


Put you JavaScript in a function and use DOM events handler to specify the event that triggers or calls the function.

Document.getElementByID(name) allows you to use the object in the JavaScript code. Use PHP _POST['HTMLelementName']  or _GET to get the form values,
