Example :
Code Class
public class EFClient
    EFClientGUI gui;
    public EFClient(){
    public void dosomething(){
         gui = new EFClientGUI ();
         gui.Label1.getText(); ---> i get a nullpointexception here
}GUI CLASS :
public class EFClientGUI extends javax.swing.JFrame {
    public EFClient efClient;
    public EFClientGUI(String teste){
        efClient=new EFClient();---> this will call the "code"
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
     try{
        efClient.dologin("Duarte","Rui");---- calls code class
     }catch(Exception ex){
         System.out.println(ex);
}here a littel explanation :
I run EFClientGUI ..... it calls EFClient... and designs.... tem i click the button and i trie to do the login.... the te login writes something to GUI...
can someone help ?

My MacBook just has a white screen and a flashing file with a question mark. Please help:(

I don't really understand what's happening, but I tried to update the software. Then all these codes appeared on the screen so I help down alt, command and R and it then reset and now it's just a white screen with a flashing file and questionmark. Please help.

That is a sign that the MBA cannot locate the OSX. The storage drive may be damaged.

PLease help! GUI and Data Structure

Hey guys,
It's for my school project.
I have to write codes for GUI program for a order form.
I'm pretty much done with layout and stuff, but I couldn't figure out how to give some regulation(?) on some of the field.
For instantce, I have to regulate a user to type only two letter abbreviation on state(address) field and the Zip field has to be either 5 digit form or XXXXX-XXXX.
I Also have to include code to filter the user input and display error message if they enter wrong information.
Second, how to use actoinevent stuff?
There are three product type: a,b, and c. If "a" be chosen, then the product name associating the "a" product has to be shown on the product name field(I used ComboBox), and the price for that product(for instance a-1) has to be shown on the price field.
Third, It sounds stupid question, but how to display current date on the java program using API?
Fourth, I have to load some of the order from external files(maybe text files) and display into the screen.
Here is the code

Help with load and unload swf file.

hello, just now i try, to load my file using the code snippet 'load and unload' i manage to load the next file succesfully but why my recent file still appear in the background? how do i make it gone?

When you load another SWF you're loading it 'inside' the current SWF but it appears that you want to replace the current SWF entirely with the new SWF, is that correct?
If so you should make what's usually known as a 'stub' or a loader. Make an empty project that merely acts as a loader. It should load your first SWF and when you press a button on that first SWF to load a second SWF, it should signal the 'stub' it's loaded inside to unload the first SWF and then load the second.
e.g. a stub.swf (just coding out of memory, not error checked, just to give a general idea):
// make a new loader to do all the loading of SWFs
var loader:Loader = new Loader();
// and display
addChild(loader);
// a function to load a SWF into the loader (replacing any existing SWF)
function loadSWF(path:String):void
     // assure path is defined or do nothing
     if (!path) return;
     // load requested SWF
     loader.load(new URLRequest(path));
// load initial SWF
loadSWF('/path/to/1.swf');
For your 1.swf to use the function, you're currently inside the .content property of a Loader so I believe you can just run a command like: Object(this.parent.parent).loadSWF('/path/to/2.swf');
This example obviously lacks any error checking or transitions but you can add those and season to taste.

PLS help. Exract and use a file in rt.jar

Hi all,
On another thread I was told I might be able to do this. I have my rt.jar file (the class for the plugin). I need to able to allow my applet to use the hashmap and arraylist without the overhead of having to load the entire vm from SUN.
I can view the contents and finding arraylist is simple but not HashMap. Any 1 know its location?
Now if I do this I need to be able to package my own jar with them in. How do I define the imports for the java files? Do they need altering from:
import java.util.Hashmap?
Can someone pls help here im at my wits end :-(

Modularisation is critically important - good to see this being addressed.
I would approach the problem by creating a special utility package that provides the upgrade/rollback steps - with logging.
The package interface would look something as follows:
create or replace package PatchLib as
--// retrurns the version banner of the library
function Version return varchar2;
--// patch instructions
procedure AddColumn( tableName varchar2, columnName varchar2, dataType varchar2 );
procedure DropColumn( tableName varchar2, columnName varchar2 );
..procedure interfaces for adding/dropping constraints, indexes, etc - with all procedures
writing to a log table the parameters they are called with, where and when, the dynamic
DDL created, and the result of the DDL..
end;Each of the patch steps (procedures) will of course do the checks such as, does the table exists, can the column name be added (does it already exist) and so on.
Your SQL*Plus patch script will include the latest version of PatchLib to install, together with the actual patch instructions. Something along the following lines:
--// patch 5.4.3.2.1
--// patchlib must be successfully installed for patching to
--// happen, thus terminate script if there are errors
whenever SQLERROR exit failure
prompt Installing Patch Library
@@patchlib.pks
@@patchlib.pkb
--// this will fail if PatchLib failed to compile successfully
prompt Verifying PatchLib is okay..
select PatchLib.Version() as VERSION from dual;
--// whenever SQLERROR can now be turned off if needed
prompt Executing patch instructions..
begin
PatchLib.AddColumn( 'EMP', 'SUPERVISOR', 'NUMBER(6)' );
.. etc ..
end;
--// a select statement can now be used on the PatchLib log table to
--// to display what the patch did
select ...
--// optionally, remove patchlib
drop package PatchLib;
prompt Patch installed.
exitThe one issue to note is that a change to the PatchLib log table, will itself need to be done carefully - as changes to that table can invalidate PatchLib and cannot thus be done using PatchLib itself.

Hi can anyone help with a mac that had magnet put on it. I turned it on and then off but a white screen appears with a file with a question mark on it?

Hi can anyone help with a mac that had magnet put on it. I turned it on and then off but a white screen appears with a file with a question mark on it?

File icon with ? mark on it means it can't read from the hard drive. The hard drive is now wiped or bad. If just wiped then you will need to reinstall your operating system, OS X. If bad you will need to replace the drive.
Start with booting the computer from the OS X install DVD that came with your system. If the Mac came with Lion Pre-Installed then you use the Lion internet recovery system to reinstall (Hold down Command+r keys or Command+Option+r keys to boot the computer from over the internet to the Lion recovery HD system).
Good Luck.

HT3964 I just opened up my MacBook Pro after a few days of not using it and it was frozen. I turned it off and back on and all I see is a white screen, there was a file with a question mark flashing for a bit but I can't do anything, please help me!!

Jerricayoung,
you have a 13-inch Mid 2012 MacBook Pro. It’s modern enough that it supports booting into Recovery mode. To do so, hold down a Command key and the R key as you start up. It should eventually show a Mac OS X Utilities menu. Select Disk Utility from that menu; when the Disk Utility window appears, select the bootable volume from the left-hand side of the window. (It’s typically called “Macintosh HD”.) When the volume is selected, some buttons will appear on the right-hand side. If it’s not greyed out, press the Verify Disk button; if it is greyed out, or if it reports on errors that it found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu; that will restart your MacBook Pro in its normal mode. With luck, that will be enough to get you to your normal login screen, rather than the white screen.

(Urgent help needed) how to read txt file and store the data into 2D-array?

Hi, I have a GUI which allow to choose file from the file chooser, and when "Read file" button is pressed, I want to show the array data into the textarea.
The sample data is like this followed:
-0.0007     -0.0061     0.0006
-0.0002     0.0203     0.0066
0     0.2317     0.008
0.0017     0.5957     0.0008
0.0024     1.071     0.0029
0.0439     1.4873     -0.0003
I want my program to scan through and store these data into 2D array.
However for some reason, my source code issues errors, and I don't know what's wrong with it, seems to have a problem in StringTokenizer though. Can anybody help me?
Thanks in advance.

1) Next time use the CODE tags. this is way too much unreadable crap.
2) The problem is your String[][] data.... the only place I see you do anything approching initializing it is
data = new String[numLines][];I think you want to do this..
data = new String[numLines][3];anyway that's why it's blowing up on the line
data[row][col]=st.nextToken();

please help my for adjust my code, where is the errors?
i use tomcat 5.5

Likely because you are not setting the content length. The rest of the code doesn't look fine however.
At the bottom of this article you can find a valuable downloadFile() snippet which might give new insights: http://balusc.xs4all.nl/srv/dev-jep-pdf.html
By the way, please use normal topic titles. You don't need to put pressure. We don't care less if it is urgent or not. That is totally your own problem.

Java GUI and runtime().exec help

I have been working on a GUI that does an assortment of tasks. The final and last task is to make copies of a 3dModel conversion program and a script file that is required to make the converter run and convert. The converter and the script file are moved to a user specified directory. The user specified directory contains all of the models that will be converted. The problem is, I can't get the GUI to boot the converter with the script file. To make the converter work, you need to pass two window's cmd commands but the commands need to occur from the same directory as the converter and script file. This is what I have tried to do:
String[] commands = new String[]{"cmd ",
"/c ",
"cd ",
smdDirectory.getPath(),
"skmodel ",
"model_definition.txt "};
try{
Process child = Runtime.getRuntime().exec(commands);}
catch(IOException e){}The files have all ready copied to the correct directory. All I need is for the GUI to execute the "skmodel model_definition.txt" commands in the correct directory. What am I doing wrong?
Thanks for the help in advance.

String[] commands = new String[]{"cmd ",
"/c ",
"skmodel ",
"model_definition.txt "};
try{
Process child = Runtime.getRuntime().exec(commands, null, smdDirectory.getPath());}
catch(IOException e){}I will try that and see if I get the desired results.
EDIT:
I got it to make. Here is the code.
String[] commands = new String[]{"cmd ", "/c ", "skmodel",     "model_definition.txt "};
     try{
          Runtime runtime = Runtime.getRuntime();
          Process child = runtime.exec(commands, null, smdDirectory);

I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work. Help?

I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work.
^^ that's the main problem. Here's the full history.
I bought a new 13" i5 MBP, early 2011 edition. I had an old white Macbook 2.14 ghz core2duo on Snow Leopard. I attempted to port over my time machine backup, but encountered problems in that my User was inaccessible from the new computer after the import finished, and I had to go in and change the root password, etc, and for some reason or another, I couldn't install any programs at all from that administrator's account. By "couldn't" I mean I could install them, but upon installation they would never boot. So, I took it to the apple store and did a clean install from the most up to date Lion OSX. Then, I created a brand new admin account, instead of trying to import the old one, and things seemed great. Then, I just imported my old files from the TM backup, but not any system settings, permissions, or user data. Just my Docs, pics, vids, apps, and itunes stuff.
Here's where things get weird again. I imported this stuff under the name "old", but all of these folders have a red negative sign on them, marking them as restricted. So, from my main admin account, I cannot even peruse these folders. Since I didn't import user data, I can't sign in to the "old" account to change permissions. I already tried to change the permissions from system preferences, but that didn't change anything. And now, for whatever reason, of all the apps that were imported then, MS Office is the only set of apps that does not work. When I click on it, it just says there was a problem and asks if I'd like to send a report to apple. I tried reinstalling it to no avail. I'm an English student, so i really need access to Word. Can anyone help? The Apple store is a major detour for me and would like to fix this issue myself.

Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.)
