ComponentUI - How-To differences between Java 6u22 and later?

Hello,
i've implemented some special-paint-methods using ComponentUI-classes.
I've only tested this against java 6u22 on Windows.
Now my first user showed me that it doesn't work with java 6u25.
After installing 6u25 on my computer, I get the same result.
Mostly the frame and its children isn't repainted correct and the menubar isn't painted.
I tried to debug this with Eclipse hoping to get some exceptions, but none occurred.
Then I goggled to find any readme/changes/howto-modifications.
But again, I found nothing!
Can someone point me to that documentation please?
Thanks in advance

Sorry if my english was not correct enough!

Thus I wanted to know, where I can find the "readme changes from java 6u22 to 6u25"! Any help with the link would be much appreciated! I wasn't able to find that myself so far!

Difference between Java class and JavaBean?

What is the difference between a Java class and a JavaBean?
A class has variables which hold state.
A class has methods which can do things (like change state).
And if I understand a JavaBean it is rather like a BIG class...
i.e.
A JavaBean has variables which hold state.
A JavaBean has methods which can do things (like change state).
So, what's the difference between the two?
And in case it helps...What is the crossover point between the two? Is there a minimalist type JavaBean which is the same as a class? What is the difference between Java beans and Enterprise Java Beans?
Thanks.

Introspection, as I understand it is a bunch of
methods which allows me to ask what a class can do
etc. right? So, if I implement a bunch of
introspection methods for my class then my class
becomes a JavaBean?Introspection allows a builder tool to discover a Bean's properties, methods, and events, either by:
Following design patterns when naming Bean features which the Introspector class examines for these design patterns to discover Bean features.
By explicitly providing the information with a related Bean Information class (which implements the BeanInfo interface).
I understand now they are completely different.
Thanks. Very clear.
I do not understand how they are completely different.
In fact I don't have a clue what the differences are
other than to quote what you have written. In your
own words, what is the difference? This is the "New
to Java Technology" forum ;-) and I'm new to these
things.In that case ejbs are way too advanced for you, so don't worry about it.

Whats is difference between Java JRE and Java SDK

Hi,
what is the difference between Java JRE and Java SDK...
i think both of them have the same set of files to be installed...
I am not able to understand where they differ

The JRE (Java runtime Environment) contains just the stuff necessary to run Java and the SDK (System Development Kit) contains the extra stuff necessary (and also helpful) to develop in Java.

What's the difference between Java SDK and the Enterprise Edition?

What's the difference between Java SDK and the Enterprise Edition? Are they both free?

both r free but they are used in diffrent applications. sdk are used for simple apps that run on your computer while j2e (enterprise edition) are ment for large distributed computer systems that include servers and such. if you don't know the diffrence you probably wont need the the j2e, only the sdk.

Difference between Java applet and JavaFX

Hello, all!
I am studying javaFX in general. As far as I understand there is no main difference between java applet and javafx, except javafx has different syntax and library simple to use. Is it right?

Basically, yes. But as you point out, it is supposed to be faster to develop in JavaFX...
For example, Processing allows to export to applet, and is strong on doing graphics, but to see if user has clicked on a circle, you have to check the mouse coordinates against the circle coordinates, or create your own Circle class: it is at a much lower level.
Likewise, you can use gaming frameworks like Slick2D or PulpCore, but they might be lacking on GUI (but perhaps faster). Or use Apache's Pivot, strong on GUI, but perhaps lacking a bit on graphics and animation.
It depends on your needs, if you prefer to stick to Java, etc.

can some one tell me the difference between
java.exe under bin directory of jdk and
java.dll under bin directory of jre under jdk.java.dll is the library containing the Java Virtual Machine. java.exe is the
program you execute to run Java. It uses java.dll. The java.dll can also be used
to invoke Java classes from other languages using the Java Native Interface (JNI), see

Question about main difference between Java bean and Java class in JSP

Hi All,
I am new to Java Bean and wonder what is the main difference to use a Bean or an Object in the jsp. I have search on the forum and find some post also asking the question but still answer my doubt. Indeed, what is the real advantage of using bean in jsp.
Let me give an example to illustrate my question:
<code>
<%@ page errorPage="errorpage.jsp" %>
<%@ page import="ShoppingCart" %>

<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
<html>
<head><title>Shopping Cart</title></head>
<body bgcolor="#FFFFFF">
Your cart's ID is: <%=cart.getId()%>.
</body>
<html>
</code>
In the above code, I can also create a object of ShoppingCart by new operator then get the id at the following way.
<code>
<%
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
%>
</code>
Now my question is what is the difference between the two method? As in my mind, a normal class can also have it setter and getter methods for its properties. But someone may say that, there is a scope="session", which can be declared in an normal object. It may be a point but it can be easily solved but putting the object in session by "session.setAttribute("cart", cart)".
I have been searching on this issue on the internet for a long time and most of them just say someting like "persistance of state", "bean follow some conventions of naming", "bean must implement ser" and so on. All of above can be solved by other means, for example, a normal class can also follow the convention. I am really get confused with it, and really want to know what is the main point(s) of using the java bean.
Any help will be highly apprecaited. Thanks!!!
Best Regards,
Alex

Hi All,
I am new to Java Bean and wonder what is the main
difference to use a Bean or an Object in the jsp. The first thing to realize is that JavaBeans are just Plain Old Java Objects (POJOs) that follow a specific set of semantics (get/set methods, etc...). So what is the difference between a Bean and an Object? Nothing.
<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
In the above code, I can also create a object of
ShoppingCart by new operator then get the id at the
following way.
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
...Sure you could. And if the Cart was in a package (it has to be) you also need to put an import statement in. Oh, and to make sure the object is accessable in the same scope, you have to put it into the PageContext scope. And to totally equal, you first check to see if that object already exists in scope. So to get the equivalant of this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart"/>Then your scriptlet looks like this:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = pageContext.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    pageContext.setAttribute("cart", cart);
%>So it is a lot more work.
As in my mind, a normal class can also
have it setter and getter methods for its properties.True ... See below.
But someone may say that, there is a scope="session",
which can be declared in an normal object.As long as the object is serializeable, yes.
It may be
a point but it can be easily solved but putting the
object in session by "session.setAttribute("cart",
cart)".Possible, but if the object isn't serializable it can be unsafe. As the point I mentioned above, the useBean tag allows you to check if the bean exists already, and use that, or make a new one if it does not yet exist in one line. A lot easier than the code you need to use otherwise.
I have been searching on this issue on the internet
for a long time and most of them just say someting
like "persistance of state", "bean follow some
conventions of naming", "bean must implement ser" and
so on. Right, that would go along the lines of the definition of what a JavaBean is.
All of above can be solved by other means, for
example, a normal class can also follow the
convention. And if it does - then it is a JavaBean! A JavaBean is any Object whose class definition would include all of the following:
1) A public, no-argument constructor
2) Implements Serializeable
3) Properties are revealed through public mutator methods (void return type, start with 'set' have a single Object parameter list) and public accessor methods (Object return type, void parameter list, begin with 'get').
4) Contain any necessary event handling methods. Depending on the purpose of the bean, you may include event handlers for when the properties change.
I am really get confused with it, and
really want to know what is the main point(s) of
using the java bean.JavaBeans are normal objects that follow these conventions. Because they do, then you can access them through simplified means. For example, One way of having an object in session that contains data I want to print our might be:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    session.setAttribute("cart", cart);
%>Then later where I want to print a total:
<% out.print(cart.getTotal() %>Or, if the cart is a JavaBean I could do this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session"/>
Then later on:
<jsp:getProperty name="cart" property="total"/>
Or perhaps I want to set some properties on the object that I get off of the URL's parameter group. I could do this:
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    cart.setCreditCard(request.getParameter("creditCard"));
    cart.setFirstName(request.getParameter("firstName"));
    cart.setLastName(request.getParameter("lastName"));
    cart.setBillingAddress1(request.getParameter("billingAddress1"));
    cart.setBillingAddress2(request.getParameter("billingAddress2"));
    cart.setZipCode(request.getParameter("zipCode"));
    cart.setRegion(request.getParameter("region"));
    cart.setCountry(request.getParameter("country"));
    pageContext.setAttribute("cart", cart);
    session.setAttribute("cart", cart);
}Or you could use:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session">
<jsp:setProperty name="cart" property="*"/>
</jsp:useBean>The second seems easier to me.
It also allows you to use your objects in more varied cases - for example, JSTL (the standard tag libraries) and EL (expression language) only work with JavaBeans (objects that follow the JavaBeans conventions) because they expect objects to have the no-arg constuctor, and properties accessed/changed via getXXX and setXXX methods.

Differences between Java Servlet and Portlets

Hello,
May anyone let me know the differences between Java Servlet, JavaBeans and Portlets? It seems quite similar to each other... By the way, what are differences between a servlet container and portlet container? Thank you.
Charoite

JavaBeans are totally different from servlets or portlets. JavaBeans can be used in just about any environment. A JavaBean is basically a java class with a no-arg constructor which follows certain naming conventions for its get and set methods.
Servlets can only function in an "web containers" which are provided by application servers which support servlets. The main function of servlets is to process requests (usually http requests) and generate output (usually web pages). They usually perform validation and other processing and then delegate the web page generation to a jsp.
Portlets are similar to servlets but rather than generating an entire web page, their output is relegated to a portion of a page. A single web page may contain the output of several portlets. These portlets can communicate with each other. The portlet container provides the functionality to merge the output of the various portlets and the infastructure required to support the portlets.

How much difference between Premier Elements and PS VII?

How much difference is there between Premiere Elenebts and Photoshop Elements VII? Considereing upgrading, but need to know how much time I will have to spend in training?

It’s certainly worth considering the bundle PSE10 & PRE10 which is very favorably priced. The two applications seamlessly integrate. There are some interesting new video features - even for bringing your stills to life.
New color correction tools make it possible to enhance video clips, just like photos.
It’s also possible to burn HD quality movies to both Blu-ray disc and onto standard DVD’s. PRE10 is Adobe’s first consumer package with 64 bit support for enhanced performance (Windows 7 only)
Mac users were first introduced to PRE9 and can now use SmartSound® to add a variety of royalty free music soundtracks that automatically adjust to perfectly match the length of their movies.

Difference between Java Method and a java function

what is the difference between a method in java and a function
in java ?
( i have seen that main() is called a function but the others
are method )
is it for main can only be called by JVM ?
please help if u can...

Though Ceci isn't a programmer, his answer is closer: strictly speaking, Java has no functions.
The Java Language Specification, 2nd Ed, mentions the word "function" thrice: in the sense "to function as something", when talking about a C function, and in the index as "mathematical function". (Get the spec under "documentation" on the left hand side of your screen.)
So, officially, no functions.
Informally, many people use "function" and "method" as synonyms. You may even find some that calls a void-returning method "procedure" and value methods "function" (perhaps Pascal background?). And a Lisp programmer might call Runnable.run() a "thunk", but he'd just be pulling your leg.

Difference between java -jar and click ?

Hi everyone,
What is the difference between :
- doing : java -jar myAp.jar
and
- doing double click on on the file "myAp.jar"
I thought I was the same thing, but it seems that it's not ...
Thanks for your help

Thanks a lot for this information ... but it makes me much more confused ;-) !
myAp.jar is a graphical application. When I run it with doing "java -jar myAp.jar" or "javaw -jar myAp.jar" everything works fine.
But I double-click on the file, the application stops everytime it there is a line of code specific to the Jre 1.4.
For example, it stops at :
JWindow window = new JWindow();
window.setLocationRelativeTo(window.getParent());
If I put these lines into coments... the application goes well and then stops at the line :
String name = getJarName();
name = name.replaceAll(".jar", "");
which is specific to version 1.4 as well.
What is confusing is that I have Jre 1.4.2_05 installed on the computer.
C:\>java -version
java version "1.4.2_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode)
I asked the question in the forum "Java Archive (JAR) Files", I did not get answer and anyway I am not quite sure it's a jar issue ....
Has anybody an idea about that ?
thanks in advance

Is there any difference between java Beans and general class library?

Hello,
I know a Java Bean is just a java object. But also a general class instance is also a java object. So can you tell me difference between a java bean and a general class instance? Or are the two just the same?
I assume a certain class is ("abc.class")
Second question is is it correct that we must only use the tag <jsp:useBean id="obj" class="abc.class" scope="page" /> when we are writng jsp program which engage in using a class?Any other way to use a class( create object)? such as use the java keyword "new" inside jsp program?

a bean is a Java class, but a Java class does not have to be a bean. In other words a bean in a specific Java class and has rules that have to be followed before you have a bean--like a no argument constructor. There are many other features of beans that you may implement if you so choose, but read over the bean tutorial and you'll see, there is a lot to a bean that is just not there for many of the Java classes.
Second question: I'll defer to someone else, I do way to little JSP's to be able to say "must only[\b]".
