I need help with File Object in Java

Hello Experts.
I am learning Java 2 now. I have trouble with reading a JTextField and save it to a file. I have some errors that I dont know what they are. I would like someone please help me to write a short sample program to see how it work. The code from the book I have dont execute at all. And I want to use FileOutputStream and ObjectOutputStream. Thank you very much
Quoc

import java.io.*;
public class FileTest {
public static void main(String[] arg) throws Exception{
    FileOutputStream fileOut = new FileOutputStream("test.txt");
    fileOut.write("Test file".getBytes());
    fileOut.close();

Need Help With File Matching Records

I need help with my file matching program.
Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
Here is my following program code:

Much help is appreciated. Please help.

From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do.

I need help with a Object Array

I am having trouble and this maybe really simple seeing that I am fairly new to java but I have text that is being broken down in to preset part with those parts stored in Object arrays.
Now I also have a object array inside my object array. Within the second object array are the broken down parts of the text and I want to compare this text with another string so for example this is what I am trying
boolean found = false;
for (int i = 0; i < FirstObjectArray.length ;i++)
     Object[] SecondObjectArray = (Object[]) FirstObjectArray;
     if(SecondObjectArray[0] == "string")
          found = true;
          break;
     else
          found = false;
}Help would be very appreciated.

sharkura said all the OP needs at the moment. I just wanted to clarify a bit why You don't use == 99.999% of the time with objects, and never with String.
I have argued elsewhere in these forums that it is inappropriate to tell anyone that you never use == to compare objects. This has not always been accepted. I have, on rare occasions, known experienced developers to blindly compare two objects with equals(), and cite the professor that taught them, 15 years iin the past, that object references are never compared using ==, but always with equals().
However, the cases where == is appropriate and equals() is not are indeed rare, but not, in my experience, non-existent. In my statement, I probably exaggerated. And String is a case where I can probably accept that you will probably never go wrong with equals(). If the String has been pooled (see String::intern()), you can actually use either. From the javadocs: "*It follows that for any two strings s and t, s.intern() == t.intern() is true if and only if s.equals(t) is true.*"

Need help with moving objects

Hello, i'm new to java and i'm building applets with eclipse. I'm stuck on how to move and object to the left of the screen i can move it right of the screen with the
blueTriangle.slowMoveXPosition(50);
but how do i move it back again say 50. I know this easy stuff for you guys.
Do i have to put something on negative positions in the triangle class file?
Any help is much appreciated.
Thanks.

I doubt it's a standard one which anyone here would know about. I bet it's something your school provided instead, or another 3rd-party. So ask them.

PHP disaster with entropy installation need help with file location

I have a mac mini snow leopard server running 10.6.5 ,and I was trying to resolve a mcrypt module issue so that I could install wordpress and magento on some of our sites.After doing what I thought was extensive research, I decided to download the entropy php 5.30-3pkg from Marc Liyanage since it was already compiled and had an automatic install.I had the xcode tools installed and was going to attempt to compile it myself,but did not quite understand the instructions on Michael Gracie's site.When I installed the entropy package it told me that i needed to first disable the existing module,and I attempted to uncheck the php5 module,with no luck,as every time I tried to save it it rechecked itself,which I later discovered was happening because of dependency issues, as I had the mail,wiki,etc services on the sites checked. So my problem is that I wasn't aware at the time of the dependency issue,and I just renamed the module and the file name by putting a # in front of both (Inside the server admin dialog box through the pop up window).I didn't think it would hurt since is was going to be disabled,but now i get blank pages when trying to connect,and can't even see a test.php file, nor can I even locate where they say:
software is supposed to be installed into a new directory /usr/local/php5 on my boot volume. If you ever want to get rid of the package, you only have to remove this directory and a symbolic link called +entropy-php.conf in either /etc/apache2/sites or /etc/apache2/other, depending on whether you run OS X Client or Server.
Any help would be appreciated !

Thank you so much, that works just like i wanted it to as it downloads the file but then i have the problem of the file being called firename.png (or whatever i put in there instead)
using this i changed the code and made it this instead which works 100%
set download to text returned of (display dialog "Enter IGN" default answer "" buttons {"Download", "Cancel"} default button 1)
set the destination to (choose folder)
do shell script "curl -L http://minecraft.net/skin/" & download & ".png" & " -o " & quoted form of ((POSIX path of the destination) & download & ".png")
so i used the input name again with download and added a .png for the extention and now it downloads the file to the locaiton i specify with the name of the user im entering with the correct exention, 100% awesome ^^
Thank you everyone who help me with that issue, grately appreshiated

Need help with Calling objects

I have created an object named "user" and I currently have 1 Frame in my program. The first frame is called "LogonFrame" and the second is called "UserDataFrame".
In the main method of the application I declare a "User" object as user and then call LogonFrame to retreive the logon_name and password from the user. The logon_name and password will be placed in the User object to be accessed throughout the application.
When I compile the application I receive the following error message:
Error: (85) variable user not found in class GL2.LogonFrame
*I know that 85 is the line number that the error is located
*GL2 is the name of the package.
Has anyone ever encountered this error before, and if so how can I fix this error.

Need help with File system creation fro Oracle DB installation

Hello,
I am new to Solaris/Unix system landscape. I have a Sun enterprise 450 with 18GB hard drive. It has Solaris 9 on it and no other software at this time. I am planning on adding 2 more hard drives 18gb and 36gb to accommodate Oracle DB.
Recently I went through the Solaris Intermediate Sys admin training, knows the basic stuff but not fully confident to carry out the task on my own.
I would appreciate some one can help me with the sequence of steps that I need perform to
1. recognize the new hard drives in the system,
2. format,
3. partition. What is the normal strategy for partitioning? My current thinking is to have 36+18gb drives as data drives. This is where I am little bit lost. Can I make a entire 36GB drive as 1 slice for data, I am not quite sure how this is done in the real life, need your help.
4. creating the file system to store the database files.
Any help would be appreciated.

Hello,
Here is the rough idea for HA from my experience.
The important thing is that the binaries required to run SAP
are to be accessible before and after switchover.
In terms of this file system doesn't matter.
But SAP may recommend certain filesystem on linux
please refer to SAP installation guide.
I always use reiserfs or ext3fs.
For soft link I recommend you to refer SAP installation guide.
In your configuration the files related to SCS and DB is the key.
Again those files are to be accessible both from hostA and from hostB.
Easiest way is to use share these files like NFS or other shared file system
so that both nodes can access to these files.
And let the clustering software do mount and unmount those directory.
DB binaries, data and log are to be placed in shared storage subsystem.
(ex. /oracle/*)
SAP binaries, profiles and so on to be placed in shared storage as well.
(ex. /sapmnt/*)
You may want to place the binaries into local disk to make sure the binaries
are always accessible on OS level, even in the connection to storage subsystem
losts.
In this case you have to sync the binaries on both nodes manually.
Easiest way is just put on shared storage and mount them!
Furthermore you can use sapcpe function to sync necessary binaries
from /sapmnt to /usr/sap/<SID>.
For your last question /sapmnt should be located in storage subsystem
and not let the storage down!

Need help with File to SOAP sync scenario: NO_BACK_SYSTEM_IN_HOPLIST

Hello,
I am setting up a new scenario where I get an XML file with PI, send that content via sync SOAP receiver call and direct the result of the web service response to SAP (just back to file as intermediate step).
So far I have the transaction working to the SOAP adapter receiver request / response. I see the correct approval response coming in my SOAP channel (RWB AE payload), but this message gets stuck there before routing back to my receiver interface and mappings.
General setup:
FILE Sender to SYNC OB SI.
OB SI Request is my source message type and Response is my final message output type.
OM Source is this Sync OB SI. Target is a SOAP Sync IB SI. Request Mapping program matches the source file message type and target SOAP layout. Response Mapping matches SOAP response and Target is my final file layout.
Routing for Sync OB SI ID uses this OM for Sync IB SI.
SYNC IB SI has Request and REsponse messages mapping the external SOAP call.
When I test the configuration I get success.
When I send messages through I get error in the adapter about this NO_BACK_SYSTEM_IN_HOPLIST (therefore the response message is not making it back into the IE so that it can be mapped again and forwarded).
Complete error message from RWB Adapter Log "Transmitting the message to endpoint http://[myhostname]:[myport]/sap/xi/engine?type=entry using connection SOAP_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: NO_BACK_SYSTEM_IN_HOPLIST:." and the next line is "Received XI System Error. ErrorCode: NO_BACK_SYSTEM_IN_HOPLIST ErrorText: null ErrorStack: Legacy system to which acknowledgment message is to be sent is missing in hoplist (with wasread=false)"
Any ideas for me? (fyi not using BPM).

Need help with file conversion

New to JMS. I want to take data which has been put into XML form, validate it, put it into a Topic (Oracle's AQ is the implementation), have a subscriber grab it and use XSL to map the elements to DB columns and insert all the data into the DB.
This way, I hope to reuse the same inserter, and just use a different mapping for each XML doc.
I am having trouble in the area of converting the files, and/or the Document objects you get from parsers, to and from Strings so that I can put them into, and get them out of, TextMessages.
What is the best way to go about this? Any and all advice would be appreciated.
-Erik

Need help with rounding numbers in Java

I finally have this program to where it needs to be except for one thing. The variable "freetime" isn't showing any kind of output in the applet. The variable sum and freetime are both called at the start of the program, and have equations to figure out the output for them, but only sum shows an output. I tried using brackets as opposed to multiple parentheses. What can I do to fix this so that there is an output? I was thinking of using something to round up the result, but I can't figure it out. Can anyone help?
import java.awt.*;
import javax.swing.*;
public class FinalLab extends JApplet{
String firstNum, secondNum, thirdNum, fourthNum, fifthNum;
int personal, family, school, work, sleep, sum, freetime;
public void init()
String firstNum, secondNum, thirdNum, fourthNum, fifthNum;
firstNum = JOptionPane.showInputDialog( "Enter total personal hours." );
secondNum = JOptionPane.showInputDialog( "Enter total family hours." );
thirdNum = JOptionPane.showInputDialog( "Enter total school hours." );
fourthNum = JOptionPane.showInputDialog( "Enter total work hours." );
fifthNum = JOptionPane.showInputDialog( "Enter total sleep hours." );
personal = Integer.parseInt( firstNum );
family = Integer.parseInt( secondNum );
school = Integer.parseInt( thirdNum );
work = Integer.parseInt( fourthNum );
sleep = Integer.parseInt( fifthNum );
sum = (personal + family + school + work + sleep);
freetime = ((168-sum)/168)*100;
public void paint(Graphics g) {
super.paint( g );
g.drawRect( 15, 10, 270, 20 );
g.drawRect( 15, 35, 270, 20 );
g.drawRect( 15, 60, 270, 20 );
g.drawRect( 15, 85, 270, 20 );
g.drawRect( 15, 110, 270, 20 );
g.drawRect( 15, 135, 270, 20 );
g.drawRect( 15, 160, 270, 20 );
g.drawString( "Personal hours: " + personal, 25, 25);
g.drawString( "Family hours: " + family, 25, 50);
g.drawString( "School hours: " + school, 25, 75);
g.drawString( "Work hours: " + work, 25, 100);
g.drawString( "Sleep hours: " + sleep, 25, 125);
g.drawString( "Total hours: " + sum, 25, 150);
g.drawString( "Free time: " + freetime, 25, 175);
}

I am guessing that you really meant that you are seeing "Free time: 0" instead of what you said, which was that it wasn't showing any kind of output. (Your whole terminology is weird, you don't "call a variable" just for example.) If that's the case, it's because you are using integer division. You'll find that 27/168, for example, gives zero. I don't know why you are multiplying by 100 in your calculation and doing the division, perhaps you meant to return the free time as a percentage (in which case your output should say that), but since you are doing that you could do it this way:((168-sum)*100/168)Then you are doing 2700/168, which produces a reasonable number.

I just upgraded to CP 5. Need help with drawing objects.

I am trying to put a simple drawing object around a word. Like a square. I can't figure out how to not have any fill, just the outline of the box. Any suggestions? I was able to do this in CP 4.

Hi there
Personally, I'd use a Highlight Box to accomplish this. But that's just me.
Here are the steps for a square drawing object. I'll assume you have already inserted the object and placed it and all you want are instructions for dealing with the fill.
Look inside the properties inspector at the Fill & Stroke section. Click the Fill color and configure Alpha to 0%.
Cheers... Rick

Need help with ABAP coding using java

Dear experts,
I have used ABAP to code many reports/function modules.However as i know java quite well,i want to achieve the same using java.I have utilized JCO to retrieve information from RFC in this mission.
However i realized that i had to code all things using ABAP and use java only as interface to connect to
SAP fetch that module and display information on console.It was not that fun.
I want that i should not Login to SAP but work only using java.
I heard SAP Netweaver is a good choice.But i dont know much about it.Will i be able to develop reports only by java and how ?
Plz suggest.

hi,
I hope that you already have the J2ME Toolkit and that your emulator works okay. In the toolkit you get several examples to show you how to program a MIDlet. One has to do with a HTTP client server connection. Also in the API documentation for the J2ME there is a Connector class that you used to set up this communication and in the description of this class it pretty thoroughly explains how to set up an HTTP protocol client.
However, if you want to do some other kind of networking then you are pretty much out of luck, as the TCPIP socket protocol has not been fully implemented and is optional to the J2ME specifications, only the HTTP protocol is certain to be available. This means that mobile phone companies can add other networking functionality to their phone's java virtual machine if they feel like it. This is a bummer I know.
I hope this helps.
Cheers,
Mark

Noob Needs Help with File Size

I created a simple form with no graphics, fonts are not embedded, and I selected the file to be filled out, printed, then mailed. The file size is 21MB. The form is to be emailed so it must be much smaller in size. Once received, the user will fill it out electronicly, print the form, then mail it back to me regular postal mail. Why is the file size so large and how can I make it smaller? Thanks in advance.
Kevin

OK. Here's what I did:
1. At the welcome screen I selected "New Form" and then "New Blank Form"
2. For the page size I left it at "Default" which is 8.5 x 11.
3. For Return Method I selected "Fill then Print".
4. At the last screen I just clicked "OK".
5. Then I built the form. I put in (9) Text boxes, (4) Text Fields that look like Sunken Boxes, (5) Numeric Fields that look like Sunken Boxes, and (3) Check Boxes that look like Sunken Boxes.
6. I then saved the file as a Static PDF Form File.
7. The file size is 22.5 MB.
That was my second attempt. The first attempt I had the fonts embedded and I had a Logo on the form. The file size for that one was 27.3 MB.
Thanks for the help.
Kevin

Need help with class object? Please somoen

hey guys,
It's been few days since i'm working on making a small bingogame program but i'm getting stuck frequantly.
I've different classes, in the main class i'm asking the user to input number of players who would like to play then i'm asking the player's name and how many bingoCards each player wants.
I'm stroing all that info in a BingoPlayer class's array object. But for some reason when i get out from the loop and try to retrive the info from that array it only gives me the last input entry (player's name & number of cards) at any index of the array.
Can please someone tell me how i can store the given information for each player in that object array on different indices of the array?
I'm providing the code where i've the problems:
public class BingoGame
    public static BingoPlayer players[] = new BingoPlayer[5];
    public static void main() throws IOException {
        int numPlayers = 0;
        int numCards [] = new int [5];
        String name [] = new String[4];
        BufferedReader input = new BufferedReader (new InputStreamReader(System.in)); //allows input
// ask for the number players who wants to play
        System.out.print("Please enter the number of players in this game (2-5): ");
        numPlayers = Integer.parseInt(input.readLine());
// make sure the entered value is within range
        while (numPlayers < 2 || numPlayers > 5) {
            System.out.println("Invalid number of players ");
            System.out.print("Please enter the number of players in this game (2-5): ");
            numPlayers = Integer.parseInt(input.readLine());
        System.out.println();
//ask for the names and numebr of cards for entered number of players
// and make sure the number of cards are within the range,
//and assign the players that many cards using the BingoPlayer object
        for (int i = 1; i <= numPlayers; i++) {
            System.out.print("Please enter name of player " + i + " : ");
            name[i] = input.readLine();
            System.out.println();
            System.out.print("Please enter the number of cards (1-5) for player " + i + " : ");
            numCards[i] = Integer.parseInt(input.readLine());
            while (numCards[i] < 1 || numCards[i] > 5) {
                System.out.println("Invalid number of cards for the player " + i);
                System.out.print("Please enter the number of cards (1-5) for player " + i + " : ");
                numCards[i] = Integer.parseInt(input.readLine());
            System.out.println();
            players[i] = new BingoPlayer(name, numCards[i]);
* here it only prints out the information for the last player, instead it should return the information for both of the player
for (int k = 1; k <= numPlayers; k ++) {
System.out.println(players[k]);
//players[k].genCards();
for example if i enter 2 players:
Player1: name: Jami, number of cards 1
Player2: name: Joey, number of cards 2
in the last loop it just prints out :"Joey, 2" 2 times instead of printing out: "Jami, 1" & "Joey, 2"
Please someone help! i really need to complete this within 2 days. Thanks in advance

Without seeing BingoPlayer's implementation, all it
would be would be a guess.
My guess: The name and numCards members of that class
are declared as static, so all instances share the
same values.Thanks it worked, declaring them static was the main probelm..thank you very much
