Thank you,sharkura,I've solve the IO problem myself

finally, I figure it out
if you try to use FileReader to read the java program you are writing ,you will get in trouble.
as I mentioned before,I get confused when I use FilreReader to read sth written by FileOutputStream(which should write binary file) and it also works, but actually when I use fileOutputStream to write, the input content have already defined as int or some specific data type by me before, and the data type has already encoding it ,thus it is not pure binary file, when we input it , it can be decoded into the primitive type again . However it looks like that FileOutputStream has done the encoding to it.

FileInputStream obtains input bytes from a file in a file system
FileReader is a Convenience class for reading character files.
So you can use FileInputStream to load any file, in any format - txt, jpg, gif
FileReader should only be used on plain text files. It won't work trying to read in image data :-)

HI ,We would like to ask you to help us with the following problem

We would like to ask you to help us with the following problem. As usual we tried to post unmatched received advance payment which is subject to output VAT via transaction SM35. Normally we post the payment to account 501020 (Advances Received from Operating Activities), we generate output VAT by clicking on u201CSimulate Taxu201D. Then we simulate the document and four lines are automatically generated (please see the attached scan of such document posted recently):
40           510000 (Trade Receivables - Receive from Bank)
19           501020 (Advances Received from Operating Activities)
50           400000 (Output Tax (Sales Tax Payable))
40           405033 (Customer Advances VAT)
However when we tried to post it today it is not possible and an error message u201CTax clearing account 405033 may not have open item managementu201D appears u2013 please see the scanned printscreen. This did not happen in the past.
We would appreciate if you could solve it as soon as possible as we still need to post it to period 12.

Hello
You execute the t/code FS00 for G/l 405033 and go the control tab select tick in open item mgt under act mgt in co.code.

How to solve the setColor() problem with multithreading?

My fractal program uses a custom number of threads to draw the complete image. If I use just 1 thread, the image looks clean, if I use more threads some pixels of the image gets other colors. The problem ist the painting code:
g2d.setColor(col);
g2d.drawLine(x, y, x, y);as it is necessary to first set the color of the graphics object and then draw the line. I can solve this pixel color problem by synchronizing the Graphics2D object:
synchronized (g2d) {
g2d.setColor(col);
g2d.drawLine(x, y, x, y);
}but this slows the code down to times where just 1 thread is calculating the image. Unfortunately, I can't find a draw() method that has a color parameter.
I tried to divide the panel into multiple BufferedImages (1 for each thread) which solves the pixel problem but only the first BufferedImage get's drawn.

I solved my problem now. My solution is to use a separate BufferedImage for each Thread. I still had a bug where i didn't transformed the x/y coordinates of the complete image to the shifted x/y coordinates of the single BufferedImages, so that the threads draw the image out of the visible area which looked like all threads after the first only had a black image. After adjusting teh coordinates, the fractal now gets drawn correctly. And boy it's much faster with multiple threads - even on single core systems. On a dual core system, using 10-20 threads about doubles the performance as both cores have work almost all the time until the fractal is finished. :-)

When apple will solve the wifi problem ?

when apple will solve the wifi problem ?

They keep trying, but haven't yet in all the time OS X has existed. Every version of OS X has had some WiFi issue with some group of users. The normal pattern is they release a fix for one group, and another group develops a new WiFi problem.

TS1559 WIFI solutions proposed by Apple are not working. Does oneone how to solve the WIFI problems?

Dear Apple.
I was really happy with my iphone4s, IOS 6.0, great product amazing quality and posibilities BUT.......
I updated from IOS 6.0 to 6.1.1. and the WIFI nightmare started.
I waited for a new update to fix the WIFI problems and I updated my iphone 4s from 6.1.1. to 6.1.2. in order to solve these problems related with WIFI connections.
But IOS 6.1.2. is even worst:
- WIFI is not working at all. So I cannot download apps greater than 50MB.
- Battery life is shorter than ever.
- 3G goes in and out every minute.
- When you operate the iphone4s you can realize that is hotter than before.
These problems are unnaceptable and inconsistent with a high quality standard product.
You can read a lot of blogs, I am not the only one.
Please give us a solution as soon as possible.
Best Regards

Trying to solve the hashtable problem;

this is a test of a part of my programming, trying to solve the hashtable
i took out the erronous part and change some of it.i'm trying to print out a table of data with 4 column
import java.util.*;
public class test {
     // creating a global hashtable name "b" its
     //static just for the convieniet of it
static Hashtable b = new Hashtable();
public static void addItem(String keyid, String t, double p, int q){
// array size of 4 for my value in hashtable "b"
String [] array = new String [4];
// puting all my variables into string array
//including my keyid as the first in array[0]
     array[0]=keyid;
     array[1]=t;
     array[2]= String.valueOf(p);//casting of double type to string
     array[3]= String.valueOf(q);//casting of int type to string
     b.put(id,array);//setting key = id and value = my array[]
public static void main (String args[]) throws Exception {
     String numb = "009", piss="theone";
     double cost = 19.50;
     int a = 1;
     String [] testItem;
     addItem(numb,piss,cost,a); //call of method additem;
     Enumeration e = b.keys();
// Get all values
while ( e.hasMoreElements())
{            tempItem = (String [])e.nextElement(); **// error msg here**
     System.out.println("array element 1"+tempItem[1]);
     System.out.println("array element 2"+tempItem[2]);
     System.out.println("array element 3"+tempItem[3]);
this is my error msg "ClassCastException: java.lang.String cannot be cast to [Ljava.lang.String;"
1 =====>cannot find symbol
symbol : variable id
location: class test
        b.put(id,array);//setting key = id and value = my array[]
2 ===>cannot find symbol
symbol : variable tempItem
location: class test
tempItem = (String [])e.nextElement();
3 ====>cannot find symbol
symbol : variable tempItem
location: class test
System.out.println("array element 1"+tempItem[1]);
is there anyway to solve this or anyone can provide me with an alternative way of printing a table with 4 col?

you should learn to post your code inside code tags

here you are iterating through the keys of the hash table ("b.keys()"), and your key is a String, not a String[; perhaps you want the value instead?

How to solve the certificate problems in Java Web Start

Hi, All,
I encounted these two problems recently:
(1) I have an application which is supposed to be started by Java Web Start. I have written my own code which calls other .jar files from other companies. Since for web start, you need to sign all .jar files if you want more permssions. Now I got the following problem:
'=================================
An error occurred while launching/running the application.
Title: My stuff
Vendor: UCLA
Category: Launch File Error
JAR resources in JNLP file are not signed by same certificate
=================================
How to go around this? It seems that the .jar files from that company has been signed already. Then I tried to uncompress those jars and re-archieve again, then sign it again using the keystore I used to sign my own .jar files. It still does not work. Any help on this will be appreciated!
(2) Afterr I signed a .jar file, when I want to run it again, using command: java -jar abc.jar
It does not work any more, I am not sure whether it will become a problem if loaded by Web start.
Thanks a lot!
David

In another forum answer, a user named Dietz suggested the following:
If you have a library signed by another signer, you need to factor it out into a seperate extension jnlp file.
