Using List Class in java.awt / java.util ?
have a program that:
import java.util.*;
List list = new LinkedList();
list = new ArrayList();
... read a file and add elements to array
use a static setter
StaticGettersSetters.setArray(list);
next program:
import java.awt.*;
public static java.util.List queryArray =
StaticGettersSetters.getArray();
If I don't define queryArray with the package and class, the compiler
gives an error that the List class in java.awt is invalid for queryArray.
If I import the util package, import java.util.*; , the compiler
gives an error that the list class is ambiguous.
Question:
If you using a class that exists in multiple packages, is the above declaration of queryArray the only way to declare it ?
Just curious...
Thanks for your help,
YAM-SSM
So what you have to do is explicitly tell the compiler which one you really want by spelling out the fully-resolved class name:
import java.awt.*;
import java.sql.*;
import java.util.*;
public class ClashTest
public static void main(String [] args)
java.util.Date today = new java.util.Date();
java.util.List argsList = Arrays.asList(args);
System.out.println(today);
System.out.println(argsList);
}No problems here. - MOD

How to use URL class to execute a java class/app on a remote machine?
I am a beginner in Java networking and have a question about URL programming.
How do I pass parameters to a java class/application over the web and then cause it to execute ? I then want to get the result back from the clas/app. The class/app resides on a remote machine and the protocol used is "http" protocol. OR all this is not possible through the URL and related classes ?How do I pass parameters to a java class/application over the web and then cause it to execute ? Using the HTTP protocl you can either perform a GET where the parameters are in the URL or a POST where the data is sent to the server with the request.
The server must be setup as a web server to execute code based ojn a HTTP request. Using a web server with a JSP which contains the code to execute is the simplest way to do this.
I then want to get the result back from the clas/app. The output of the JSP becomes in the data returned by the HTTP request.
I would suggest looking for example on google.

Another option is to use RMI. The integration is tighter but it does not use the HTTP protocol. -
How to use inner class in axis2 in java?
Hi,
Iam very new in axis2. My language is java. What iam trying to do is, i need to create a xml format for the clients to send data to server using axis2 service.
My demo xml format is,
<test1>
<test2>
<test3>
<test4></test4>
<test5></test5>
</test3>
<test3>
<test4></test4>
<test5></test5>
</test3>
</test2>
</test1>
Iam trying to use nested inner class to generate this xml. Below is my demo java class. But unfortunately, or may be lac of knowledge, iam unable to create sub trees.
public class EchoService{
public MyInnerClass retMyInnerClass(MyInnerClass test1) {
return test1;
public class MyInnerClass {
private String test2;
public MyInnerClass() { }
public void setTest2(String test2) {
this.test2 = test2;
public String getTest2() {
return this.test2;
Please help me to generate the web service for client.
Thanks in advance.847897 wrote:

Cannot find package java.awt
hi,
i am trying to compile my project code and i keep on getting the following two errors " package java.awt does not exist " and " package java.awt.events does not exist " why is this happening? Is there any special classpath that needs to be set? Or any other thing? please help....Are you importing using import java.awt.*; or import java.awt;
java.awt.events does not exist. Try java.awt.event instead.
Please post your import statements. -
Using text in a GUI without using .swing classes
In a Java application, is there any way to create a text object that can be positioned in a GUI like an ImageIcon (using a class from the standard Java API)? For example, when using ImageIcon, you feed the x and y-coordinates, whereas with .swing, you'd have to create a new panel, position the panel, and re-position the panel using BorderLayout.(direction).
Ex. (with ImageIcon, you'd place it like so):
//construct ImageIcon w/ URL
ImageIcon myImage = new ImageIcon(new URL("http://..."));
//x and y are pixels to the right and to the bottom from the top left corner
myImage.paintIcon( (Component), (Graphics), x, y);
//I'm looking for one that does the same, like this (without using an image, preferrably), TextMessage is what the class might be:
TextMessage myText = new TextMessage("Here is some string to print out");
myText.printText( (Component), (Graphics), x, y)or you can paint a string, like this
public void paint(Graphics g) {
super.paint(g);
g.drawString("Hello World!", x,y); // replace x, y with your own coordinates
}hope that helps -
How to create a tree structure using list items(tlist)
HI every one,
As we know how to create a tree structure using Hierarchy item type.
We have a requirement to create The same tree like structure using List Item(Tlist)
I would be so appreciated If you send with an example
Thanks
RangaReddyHi all
Any one help me please
Actually our client requirement is creation of tree structure using list item,similar to what we used in oracle Application(FNDSCSGN) form.We did the tree structure using hierarchy tree using Htree and Ftree.It working excelently.For client requirement, we want to use list item.How PJC(Pluggable Java Components) is useful for using list item(Tlist).I can't understand how it is useful.
Do you have any example please help me.
Thanks

I can't use Math.class although I import java.lang.*.
plz help me.and tell us what you mean by "can't use"My father began to work a PC as he was already
retired. He has been fighting with it ever since.
Sometimes he calls me for help crying "everthying has
disappeared!"
I ask him: "What is 'everything' and what does it
mean 'disappeared'?"you could then go on to throw a further spanner in the works by asking what "has" means :) -
Problems changing colour using Graphics class in java.awt
Hi,
The problem only happens when more than two images are on a panel. In this case, I have to strings that are drawn. The first drawn string is called "A" the second drawn string is called "B". However, when i change the colour of "B" to let's say Red, the panel erases the letter "B" and insteads changes "A" to red. How can I fix this so that when the user chooses the colour red it changes the colour of the latest drawn string and not the first one. please help!!!!
import java.awt.*;
public class StringPanel extends GBPanel
private String shape = "clear", str;
private int x, y;
private Color color = Color.black;
public void paintComponent(Graphics g)
super.paintComponent(g);
g.setColor (color);
if(shape.equalsIgnoreCase("draw string"))
g.setColor(color);
g.drawString(str, x, y);
else if (shape.equalsIgnoreCase("exit"))
System.exit(0);
public void drawCurve(Color color)
this.color = color;
repaint();
public void drawString(String shape, String str, int x, int y)
this.shape = shape;
this.str = str;
this.x = x;
this.y = y;
repaint();
public void drawString1(String shape, String str, int x, int y)
Graphics g = getGraphics();
g.setColor(color);
if (shape.equalsIgnoreCase("draw string"))
g.setColor(color);
g.drawString(str, x, y);
else
repaint();
}well, as I said, I can't remember what the update method thing was for... I think it was related to not clearing the screen first.
Anyway, if you maintain a list of objects that should be drawn and then in the paintComponent method, loop thru the list of objects and redraw them, it will work. Then you change the state of an object and call repaint. When you are going to change color, you need to, in effect, redraw the entire affected area. Now this can be done partially with clipping, but it's complicated to deal with that. So the simplest way is just redraw everything on repaint. -
Can't find class when i use java.awt.Panel
I got a Pocket PC with CE 3.0
I made my first PJava application just a few hours ago. And it works fine. But when i introduce a Panel to improve the interface then application fails on the Pocket PC with the error message "could not find class application". When i remove the Panel it works fine again.
I thought that java.awt.* is part of PJava. And even if not i should be able to introduce even a java.lang.* class to the PJava application if i use the JAR.
Any suggestion?you should provide more detail about your deployment procedures.
There are many ways to get this message. AWT in fact is part of pJava and works fine for most of us. So I assume the deployment is the problem. Have you checked the actual content of the JAR? Have you provided a path statement? How do you call your app (shortcut?) -
Problem with Horizontal Scroll on java.awt.List
I use the same code for a General Application as a CDC Application.
I have no problem at all with the General Application but on the CDC I can't scroll to the right (horizontal).

I use the PP-1.0 Profile for the CDC application. Does it not support horizontal scroll on java.awt.List?

Import the classes in the package java.util
I haven't taken a class in two years so I have ideas but am unsure of myself, and I most likely am way off base, but is this how you import the classes in the package java.util
import java.util.*;
I would appreciate anyone's help. I have a lot of questions.
Thanks,
rpMy assignment is below so that you will know exactly what I am asking. I am being asked to create an instance of LinkedList. I know that this is a part of the java.util. So when you create an instance of LinkedList would that be similar to instance variables? or am I misunderstanding something. I have several ideas, so I will start with the first one.
LinkList();
I really appreciate your taking the time to answer my questions to help me to rebuild my confidence in doing this.

Why are Java files always listed as needing repair in Disk Utility?

Baltwo, bull's eye, as always!
X423424X's question is pertinent too: you usually need to repair permissions after some major upgrade or update, not on a regular basis. Is there a particular reason why you'd often try to repair permissions? Here's more on the subject.
Repairing permissions after an update or upgrade is harmless, but I would question the need to do it even there. The Apple update itself should set the correct Permissions. I still do this, really as a hangover from Tiger days -- not certain it was really ever needed there either -- and because it's a habit that's hard to kick, but it's never found anything to repair...but for one buggy exception, which was the 10.5.8 Combo update. Running it once and then repairing Permissions created a real error. It was discovered the Combo needed to be run twice back to back and then Permissions repair. In fact, one would have been better off not running Permissions for that update to begin with. There it wasn't harnless.
https://discussions.apple.com/message/9968141#9968141
BTW, even Flash updates, which always used to set incorrect Permissions, are coming in clean these days.
