Hi,
I think you're in big trouble.
You have changed all your permissions.
Do not change anything in the directory of /bin
Just re-install

About Java 2 opaque font color question, help needed!

About Java 2 opaque font color question, help needed!
I was trying to test opaque font (the string has a foreground color and a background color), but i can't find the method for doing that.
i can change foreground by Graphics2D.setPaint(Color.black).
Anybody know how to change the background of the string?
Thanks!

Hi. The way I'd do it would be to use the font metrics to find the length of a string and draw a rectangle and then drawstring over the rectangle. If you want an example, I can post it although I suspect theres a better way.

NO NEED TO A WANKA !!
I feel a bann comming up.
Have you tryed Google ? really.. your question is inrelevant. No need to reply indeed.
Why do you come here asking this question anyway ? is it becouse you have a MSI gfx card ? and the adapter has nothing to do with this ?
You think you can come in here yelling.. thinking we have to put up with it and accept your style of posting. This is not a MSI tech center.. it's a user to user center.. Your question has nothing to do with MSI relavant things anyway's.
Google = your friend.

Help needed with Vista 64 Ultimate

"Help needed with Vista 64 UltimateI I need some help in getting XFI Dolby digital to work
Okay so i went out and I bought a yamaha 630BL reciever, a digital coaxial s/pdif, and a 3.5mm phono plug to fit perfectly to my XFI Extreme Music
-The audio plays fine and reports as a PCM stream when I play it normally, but I can't get dolby digital or DTS to enable for some reason eventhough I bought the DDL & DTS Connect Pack for $4.72
When I click dolby digital li've in DDL it jumps back up to off and has this [The operation was unsuccessful. Please try again or reinstall the application].
Message Edited by Fuzion64 on 03-06-2009 05:33 AMS/PDIF I/O was enabled under speakers in control panel/sound, but S/PDIF Out function was totally disabled
once I set this to enabled Dolby and DTS went acti've.
I also have a question on 5. and Vista 64
-When I game I normally use headphones in game mode or 2. with my headphones, the reason for this is if I set it on 5. I get sounds coming out of all of the wrong channels.
Now when I watch movies or listen to music I switch to 5. sound in entertainment mode, but to make this work properly I have to open CMSS-3D. I then change it from xpand to stereo and put the slider at even center for 50%. If I use the default xpand mode the audio is way off coming out of all of the wrong channels.
How do I make 5. render properly on vista

We ended up getting iTunes cleanly uninstalled and were able to re-install without issue. All is now mostly well.
Peace...

Help needed for using BASIC authentication through JDBCRealm

Help needed.
Hello,
I am doing a degree project, so far it works fine in my local machine, I need to try it on my virtual hosting (as it is a live server).
My project requires JDBCRealm, that is BASIC authentication loading access data from mysql database. Normally this setup can be done in Server.xml file, because my Tomcat hosting is a virtual one, I only have permission to access the web.xml file.
My question is: is it possible to get it done in an alternative way? In web.xml? Some properties file maybe?
Thank you very much.

You can set this up for your context using META-INF/context.xml instead of working with server.xml.
Make a directory called META-INF under your webapp ( it'll be at the same level as WEB-INF ). Under this, add a context.xml with all your context specific configuration including the realm. A sample is below
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/myApp" reloadable="true">
    <Realm
        className="org.apache.catalina.realm.JDBCRealm"
        driverName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
        connectionURL="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=myDB;SelectMethod=Cursor;"
        connectionName="username" connectionPassword="password"
        digest="MD5" userTable="users" userNameCol="userid" userCredCol="userpassword"
        userRoleTable="user_roles" roleNameCol="rolename"
    />
</Context>Hope this helps.

Hi everyone
Programming help needed here. Any advice would be greatly appreciated!!!
I have been assigned some work for a program called Processing 1.0 availale at http://processing.org/download
I was give the 9 individual programs I needed to make however they were converted to Java files from .pde files. The program is based on Java but only runs .pde files and NOTHING else!
I decompiled the files and got the source code, but it is a slight variation of the original someone made in processing, and needs some tidying to get it to run.
I think the programs are very simple for a programmer, although I AM NOT.

HELP NEEDED PLEASEShouting is a good way ensure you don't get help. Also you should give a meaningful subject.
Any advice would be greatly appreciated!!!I suggest you ask a question after providing enough information to be able to answer it.
Also use CODE tags when posting code as it make the code more readable.
We are more likely to help people who are trying to learn Java rather than someone who might be looking for an easy way out of doing an assignment.

Help needed to run JSTL 1.1 in Tomcat 6.0.16

Hi All,Help needed to run JSTL 1.1 in Tomcat 6.0.16. I am trying to run the example given in http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html The example tries to connect to MySQL database from JSP using JSTL and JNDI Datasource.I am running the example using Eclipse 3.4.2 using Sysdeo plugin to start and stop Tomcat server from Eclipse IDE.
My web.xml file has <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
</web-app>
and test.jsp has proper taglib directives
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I have placed the jstl.jar and standard.jarof the jakarta-taglibs-standard-1.1.2.zip under E:\Deepa\workspace\DBTest\WebContent\WEB-INF\lib directory also placedcontext.xml file under E:\Deepa\workspace\DBTest\WebContent\META-INF and the content of context.xml is as below
<Context path="/DBTest" docBase="DBTest"
debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"

username="deepa" password="mysql" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>
</Context>
Now while running the example, Eclipse creates one DBTest.xml file under C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\Catalina\localhost
which has the following line:
<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest" workDir="E:\Deepa\workspace\DBTest\work" />
I am getting the following error when running http://localhost/DBTest/WebContent/test.jsp

what is the problem with my code?
When running the same example, by creating a local server in Eclipse(creating new Server connection pointing to same Tomcat 6.0 installation) it runs fine without any error.

Hi evnafets,
Wow, very helpful information, great insight into working of Eclipse. Thanks a lot.
I have one more question. I have a context.xml file under {color:#0000ff}E:\Deepa\workspace\DBTest\WebContent\META-INF{color} folder and that has the Resource element to connect to MySQL database:
{code{color:#000000}}{color}<Context path="/DBTest" docBase="DBTest" debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" username="deepa" password="mysql" driverClassName="com.mysql.jdbc.Driver"
{color:#0000ff}url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>{color}
{color:#0000ff}</Context>{color}As usual when running application in local Tomcat server of Eclipse, this data source works fine. But when I run the application on Tomcat, by starting Sysdeo plugin from Eclipse, the DBTest.xml file created in C:\Tomcat 6.0\conf\Catalina\localhost has the context entry as<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest\WebContent" workDir="E:\Deepa\workspace\DBTest\work">
</Context>The<Resource> element I have specified in the context.xml of \WebContent\META-INF folder is not taken into account by Tomcat and it gives the following error:May 21, 2009 5:20:04 AM org.apache.catalina.core.StandardWrapperValve invoke

Help needed with header and upload onto business catalyst

Can someone help with a problem over a header please?
I have inserted a rectangle with a jpeg image in background, in the 'header' section, underneath the menu. It comes up fine on most pages when previsualised, going right to the side of the screen, but stops just before the edge on certain pages. I have double checked that I have placed it in the right place in relation to the guides on the page.
That's one problem.
The second problem is that I tried to upload onto business catalyst, which got to 60% and refused to go any further, saying it couldn't find the header picture, giving the title and then u4833-3.fr.png. The picture is in the right folder I have double checked. And it isn't a png. Does it have to be ?
And the third problem is that I got an email following my upload from business catalyst in Swedish. I am living in France.
Can anyone help ? Thanks.

Thanks for replying,
How can I check the preview in other browsers before I publish a provisional site with BC?
The rectangle width issue happens on certain pages but not others. The Welecom page is fine when the menu is active, also the contact page, but others are slightly too narrow. Changing the menu spacing doesn’t help - I was already on uniform but tried changing to regular and back.
In design mode the rectangle is set to the edge of the browser, that’s 100%browser width right?
Re BC I have about 200 images on 24 different pages and it seems to be having difficulty uploading some of them. But it has managed a couple I named with spaces but not others I named with just one name.
Is there an issue on size of pictures ? If I need to replace is there a quick way to rename and relink or do I have to insert the photos all over again?
I’m a novice with Muse with an ambitious site !
Thanks for your help.

Hi
Answering the questions :
- Have you checked the preview in Muse and also in other browsers ?
- Does the rectangle width issue happens when menu is active , or in any specific state , Try to change the menu with uniform spacing and then check.
- In design view the rectangle is set to 100% browser width ?
With publishing :
- Please try to rename the image file and then relink
- If it happens with other images as well , see if all the image names includes strange characters or spaces.
- Try again to publish
With e-mail from BC :
- Under preferences , please check the country selected.
- If you have previously created partner account in BC and selected country and language then it would follow that, please check that.
Thanks,
Sanjit

Help Needed for T42 Start-up Problem

Urgent help need!!!
I have a ThinkPad T42 with Windows XP installed. It works perfectly for a while without ever have any problem or error message. Then suddenly it won’t work anymore. The symptom is following:
After power on the laptop the Microsoft window would show up and it prompt me for window logon password. After I type in the password it then shows “window is loading your personal setting”. After a long while nothing would show up on the screen other than the background of the normal screen. There is no window bar at the bottom or any icon on the screen. If I start in safe mode then everything would show up. I don’t know what is going on.
This happened two months ago and I ended up restoring a backup image to get it work again. It happens again today with the same symptom. I am really tired of having to restore image backup every 2 months.
I would really appreciate it if any of your experts can offer me some insight into this problem. I am desperate in need of help.
Thanks very much!

wangy26, welcome to the forum,
Have a look at this thread to see if my post there helps. The problem seems to mostly occur at the start of a month, why I don't know. Unfortunately the member didin't report back whether or not this was a viable solution for them.

Hi,
Welcome to the forum!
Don't say things like "urgent" or "asap" (as in your title, "error messages help need asap!!!!"). It's rude.

Also, you store a number in my_val, but never use that number, and you have a variable called tasktotal that's never defined. Should my_val and tasktotal be the same variable?
Perhaps this is what you want:
CREATE OR REPLACE FUNCTION
       no_of_task_types (x NUMBER)
RETURN NUMBER IS
    tasktotal   NUMBER;
BEGIN
    SELECT COUNT(distinct t.task_type_no)

    AND     t.task_id        = a.task_id;          -- ; at end is important
    RETURN tasktotal;

Help needed with java

Hello everyone
I'm a Student and new to java and I have been given a question which I have to go through. I have come across a problem with one of the questions and am stuck, so I was wondering if you guys could help me out.
here is my code so far:
A Class that maintains Information about a book
This might form part of a larger application such
as a library system, for example.
@author (your name)
*@version (a version number or a date)*
public class Book
// instance variables or fields
private String author;
private String title;
Set the author and title when the book object is constructed
public Book(String bookAuthor, String bookTitle)
author = bookAuthor;
title = bookTitle;
Return The name of the author.
public String getAuthor()
return author;
Return The name of the title.
public String getTitle()
return title;
and below are the questions that I need to complete. they just want me to add codes to my current one, but the problem is I don't know where to put them and how I should word them, if that makes sense.
Add a further instance variable/field pages to the Book class to store the number of pages in the book.
This should be of type int and should be set to 0 in the Constructor.
Add a second Constructor with signature
public Book(String bookAuthor, String bookTitle, int noPages) so it has a third parameter passed to it as well as the author and title;
this parameter is used - obviously?? - to initialise the number of pages.
Note: This is easiest done by making a copy of the existing Constructor and adding the parameter.
Add a getPages() accessor method that returns the number of pages in the book.
Add a method printDetails() to your Book class. This should print out the Author title and number of pages to the Terminal Window. It is your choice as to how the data is formatted, perhaps all on one line, perhaps on three, and with or without explanatory text. For instance you could print out in the format:
Title: Robinson Crusoe, Author: Daniel Defoe, Pages:226
Add a further instance variable/field refNumber() to your Book class. This stores the Library's reference number. It should be of type String and be initialised to the empty String "" in the constructor, as its initial value is not passed in as a parameter. Instead a public mutator method with the signature:
public void setRefNumber(String ref) should be created. The body of this method should assign the value of the method parameter ref to the refNumber.
Add a corresponding getRefNumber() accessor method to your class so you can check that the mutator works correctly
Modify your printDetails() method to include printing the reference number of the book.
However the method should print the reference number only if it has been set - that is the refNumber has a non-zero length.
If it has not been set, print "ZZZ" instead.
Hint Use a conditional statement whose test calls the length() method of the refNumber String and gives a result like:
Title: Jane Eyre, Author: Charlotte Bronte, Pages:226, RefNo: CB479 or, if the reference number is not set:
Title: Robinson Crusoe, Author: Daniel Defoe, Pages:347, RefNo: ZZZ
Modify your setRefNumber() method so that it sets the refNumber field only if the parameter is a string of at least three characters. If it is less than three, then print an error message (which must contain the word error) and leave the field unchanged
Add a further integer variable/field borrowed to the Book class, to keep a count of the number of times a book has been borrowed. It should (obviously??) be set to 0 in the constructor.
Add a mutator method borrow() to the class. This should increment (add 1 to) the value of borrowed each time it is called.
Include an accessor method getBorrowed() that returns the value of borrowed
Modify Print Details so that it includes the value of the borrowed field along with some explanatory text
PS. sorry it looks so messey

1. In the future, please use a more meaningful subject. "Help needed with java" contains no information. The very fact that you're posting here tells us you need help with Java. The point of the subject is to give the forum an idea of what kind of problem you're having, so that individuals can decide if they're interested and qualified to help.
2. You need to ask a specific question. If you have no idea where to start, then start here: [http://home.earthlink.net/~patricia_shanahan/beginner.html]
3. When you post code, use code tags. Copy the code from the original source in your editor (NOT from an earlier post here, where it will already have lost all formatting), paste it in here, highlight it, and click the CODE button.

JCmboBox setSelectedIndex help needed !!!!!!!!!!!!

hi,
I hope it's a trivial question but I am not able to solve it so need your help plz. I have a demo program if you run it you will see what I mean. Actually I am adding items to my JComboBox dynamically. My problem is that if I add the items with the same name and then explicitly set them selected my first item with same name is always highlighted and selected even though I say to select the last item which I add. But when I pull down the comboBox my first item with the same name is selected and highlighted not the last one. Please run the program and see. How can I solve this problem help needed.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class ComboBoxDemo extends JPanel {
JButton picture;
public ComboBoxDemo() {
String[] petStrings = { "Bird", "Cat", "Dog", "Rabbit", "Pig" };
// Create the combo box, select the pig
final JComboBox petList = new JComboBox(petStrings);
picture = new JButton("ADD");
picture.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
petList.addItem("TEST ");
int nodeTotal = petList.getItemCount();
petList.setSelectedIndex(nodeTotal-1);
setLayout(new BorderLayout());
add(petList, BorderLayout.NORTH);
add(picture, BorderLayout.SOUTH);
setBorder(BorderFactory.createEmptyBorder(20,20,20,20));
public static void main(String s[]) {
JFrame frame = new JFrame("ComboBoxDemo");
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
frame.setContentPane(new ComboBoxDemo());
frame.pack();
frame.setVisible(true);
I want to select the last item I add even if there exists an item with same name.
Any help is greatly appreciated.
Thanks.

never mind I got the answer.

Quicktime help needed - I have an Imac 800Mhz PPC G4 with OSX 4.11 installed , Quicktime help needed? - I have an Imac 800Mhz PPC G4 with OSX 4.11 installed?

I have an Imac 800Mhz PPC G4 with OSX 4.11 installed, THANKS! Quicktime help needed?

Thanks for your kind reply Quicktime Kirk! Thanks in advance to anyone who replies to this as well. I have heard that what I need is an older Quicktime Version that allows for saving files, etc. But apple does not support it & I should look elsewhere - hence my appeal on this forum. Also, for some reason, when I try to upgrade to Quicktime Pro my browser (both Safari & Firefox) quits as I am about to complete my purchase. In any event, the real question is this: would the Quicktime Pro upgrade be compatible with my current system?

Help needed in Connecting to SAP From Eclipse

Hi All,
Currently, we have a requirement where we need to retrieve data from SAP System and need to upload the same in a Third Party Application (Java based system).
We are able to create an account in Java Application using Eclipse IDE by hard coding the Account details. We are stuck up in establishing the SAP connection and retrieving the details and then creating the extracted account details in Java application from Eclipse.
Any pointers on this will be of great help.
Regards,
Eureka

Hi Eureka,
Please refrain from creating cross-posts in parallel forums, moreover this question is JCo-related and is not directly connected with Java EE 5. The Help needed in Connecting to SAP From Eclipse in the Java Programming forum would be enough. Please continue the discussion there.
Regards,
Vladimir
