Java Sub string urgent help

Hi,
I need help with the sub string.
<fs> means field separator. (char)28.
I have a string like(This is a very big string): "0117<fs> A<fs> 0100 <fs> <fs> <fs>admin <fs>"
I need to get string like: "0117A0100 <fs>admin".
Fields in the string are fixed length but some fields may change like"admin" it can be "register".
Thanks in advance.
Bachi.

Sorry about that, its not home work I am working on message formatting now. Using regular expressions.
We get the message from the socket like
0117A0100 .admin.01010000FRAZEE.CA810FA1.admin.2 004030508342717836.1..0.0M1000030001000096..1000.
I need to spit that message in to fields and then process the message. We need to send the response back in the same format.
I want to split the string like this. there are some fields which are fixed length and other may change.
0117,A,0100, ,.,admin.,0101,0000,FRAZEE,.,CA810F,A,1,.,admin,.,2, 0040,30508342717836.1..0.0M1000030001000096..1000.
Thanks in advance.

Problems with the Strings Urgent Help needed

I have a unique problem. I have to retrieve a particular value from a String. I tried using String tokeniser but in vain. I cannot use java.util.regex package to match the expressions as the version of java on the client m/c is 1.1.8 and they are not ready to upgrade the same.
The string From which I have is a very long one running into more than 100 lines which can vary from case to case all I know is to retrieve the value which is just in front of "TestValue" which occur only once in the String Can Anybody suggest a bettter alternative.
Thanx.
ebistrio

StringTokenize on TestValueHow would you suggest that was done?
As I understand it StringTokenizer tokens = new StringTokenizer(string, "TestValue"); would not tokenize on the string "TestValue" but on any of the characters 'T', 'e', 's', 't', 'V', 'a', 'l' or 'u'. This is a common java pitfall in my opinion due to bady named parameters (I feel it should be called "delims" not "delim") or in other people's opinion due to bad parameter type (should be a char[] not a string).
A clearer explanation of the problem would help.

Excel from JAVA or C++ -- Urgent -- help

Hi
I know it might not be possible, but i want to use couple of Financial Functions which excel provides within itself.
Is there anyway i can use them from my JAVA or C++ code ?
In short, would it be possible to call excel functions from JAVA or C++ code
TIA
Vikram

Actually you can... In quite a few different ways. You can access any COM or OLE object in windows from within java by using the Java/COm bridge, or purchasing shrink wrapped products... The links are below:
These people provide some very cool solutions for java. This link is specifically for excel.

Urgent help needed(java frames)

I have written a piece of code for building a gui with some buttons, drawing some geometric shapes.The code consists of two files called Graph and Frame.

Hi,
You are very lucky that I'm currently boored. You should never tag a question as urgent. It might be urgent to you, but not to us who answer. And you should also use code formatting when you post code (see the formatting tips, or use the code-button).
I made some changes to your Graph class. The most important thing is the abstract draw method that I added to the GeomFigur class.

Urgent Help required! - Storing the XML as String instead as a file

Hi,
I need urgent help on this.
I have an XML file. I have used org.w3c.dom to build dom and manipulate the XML file.
I have updated the values for some of the nodes and I have deleted some of the unwanted nodes.
I am able to save the output of the DOM as another XML file using
either transform class or XMLSerializer with OutputFormatter class.
But my requirement is to save the output of the DOM into a String instead of a file.
When I save it in String, I need to have the following XML decalration and DOCTYPE declration also with it.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Test SYSTEM "Test.dtd">
Can anyone pls help me in this??
Thanks in Advance. Expecting some inpputs pls....!
Regards,
Gayathri.

hi,
i think this is what u want
 public static String getXmlString(Document d) {
 StringWriter strResponse = null;
 try {
 OutputFormat format = new OutputFormat(d);
 strResponse = new StringWriter();
 XMLSerializer serial = new XMLSerializer( strResponse, format );
 serial.asDOMSerializer();
 serial.serialize(d.getDocumentElement());
 catch (Exception e) {
 System.out.println(e.toString());
 return strResponse.toString();
}HTH

Help with StuckThread in java.lang.String.equals(String.java:619)

I periodically get a stuck Execute thread on my Weblogic 8.15 server
during a call to a Stateless Session Bean. When I do thread dumps, the
thread is always stuck in the same place (in
java.lang.String.equals(String.java:619) or in the call immediately above it
java.util.LinkedList.indexOf(LinkedList.java:397)). Even though the thread
dump indicates that the thread is in a runnable state, if I do multiple
thread dumps over a period of time, the stack trace always indicates that
the thread is in the same place. The thread remains stuck until Weblogic is
restarted. Other client applictions can make session bean calls, but each
stuck thread seems to still take up lots of CPU time. I have let the stuck
threads run overnight, and the stack trace from the thread dump always shows
them executing the same String/LinkedList code. In each case, our code is
trying to iterate over a collection
Does anybody know what could cause this problem, and how to fix it? I get
StuckThreadMaxTime errors in the log:

URGENT HELP NEEDED!!! (Almost a matter of life and death)

Well, it's more of a matter of failing a course or not...
Anyway, my Java professor gave us some labs to do. I know Java front and back, at least, whatever version I learned a few years back. This is my first tenure with the Scanner object, and it's messing me up.
I'm using Eclipse for my project. I have three files in the source folder, ABC_Manufacturing.java, mseast.dat and mswest.dat. Now, when I try to instanciate a new Scanner object, it won't find the files:
Scanner east = new Scanner(new FileReader("mseast.dat"));
Scanner west = new Scanner(new File("mswest.dat"));
I'm trying two seperate ways to do this. Neither are working, this is the error I get:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
     Unhandled exception type FileNotFoundException
     Unhandled exception type FileNotFoundException
     at ABC_Manufacturing.main(ABC_Manufacturing.java:38)
Now, I added these files OVER and OVER again. I added them. I created new files and pasted the contents in there. I used .txt files. All the same error. It's like it just won't take the time out to look for the files that are RIGHT IN THE DAMN PROJECT! Then I tried using a complete path, using C:\Java\whatever. SAME ERROR!!!!
Please, I need urgent help. This is due tomorrow at noon, and I have no idea what to do at this point. I can't really continue, because at this point its just looking at what prints out and formatting it, and I don't want to do that without testing to see if my code to convert the file data into arrays work. You dig? Thanks for any and all help, and I'm going to kill my professor...she spent a week going over parallel arrays but did nothing to show us how to import files into projects or use the scanner class. Also it doesn't help that at uni we have to use emacs, which I don't use at home.

This is the the main class, so far:

          int [] eastQuant = new int[13];
          int [] westParts = new int[17];
          int [] westQuant = new int[17];
          System.out.print(west.nextInt());
And I didn't ignore that one guy (sorry, don't remember your username) I tried you and the other guy's responce. Both didn't work. I dunno how to get around errors. Figures, you don't learn that in the course but she'll spend a week on parallel arrays...Ok, well that can't possibly be complaining with the same error message you got before, so now you need to be (more) specific about what "didn't work" means.

I am having problems implementing a username validaion bean for my login system. Every time I click my login icon on my main JSP page the login JSP page does not appear except one of the error JSP pages.
How can I correct this problem?
Does the code below look correct?

Urgent Help Required for Connect Four Game

Hi all,
I am a student and I have a project due 20th of this month, I mean May 20, 2007 after 8 days. The project is about creating a Connect Four Game. I have found some code examples on the internet which helped me little bit. But there are lot of problems I am facing developing the whole game. I have drawn the Board and the two players can play. The players numbers can fill the board, but I have problem implementing the winner for the game. I need to implement the hasWon() method for Horizontal win, Vertical win and Diagonal win. I also found some code examples on the net but I was unable to make it working. I have 5 classes and one interface which I m implementing. The main problem is how to implement the hasWon() method in the PlayGame class below with Horizontal, vertical and diagonal moves.
Sorry there is so much code.
This the interface I must implement, but now I am only implementing the int move() of this interface. I will implement the rest later after solving the winner problem with your help.

Hi,
Thanks for your help but I really don't understand the table lookup algorithm. Could you please send me some code to implement that.
I will send you the formatted code as well
Thanks for your help.

Getting Error:::oracle.jbo.domain.Date cannot be cast to java.lang.String

Hi Friends,
I have simple req'.
i have one date filed in OAF page...if user has change the date filed..means if he incresed by 2 days..then i need to call one procedure..if not no need to call....
first am picking that date field to by uusing prepared stmt and putting in to one variable..like below
try {
ps1 = am.getOADBTransaction().getJdbcConnection().prepareStatement("SELECT -------");
ResultSet rs2 = ps1.executeQuery();
while (rs2.next()) {
schDate = rs2.getString(1);//storing the value
} catch (Exception e) {
throw OAException.wrapperException(e);
Next..am picking the current value like this(user can change the value) like below...
OAViewObject viewObj = (OAViewObject)am.findViewObject("simpleVO");
String currSchDate = (String)viewObj.getCurrentRow().getAttribute("iDate");
java.text.SimpleDateFormat dtFormat = new java.text.SimpleDateFormat ("MM/dd/yyyy");
StringBuilder date = new StringBuilder(dtFormat.format(currSchDate));
Then am comparing the values like below..
if (schDate.equals(date)) {
String outParamValue = "";
String secondOutParamValue = "";
but am geting the below error
## Detail 0 ##
java.lang.ClassCastException: oracle.jbo.domain.Date cannot be cast to java.lang.String
at xxuss.oracle.apps.abc.webui.xxPGCO15.processFormRequest(xxGCO15.java:594)
Appriciate any help...its very urgent
Regards
Harry

Instead of :
String currSchDate = (String)viewObj.getCurrentRow().getAttribute("iDate");Try
String currSchDate = viewObj.getCurrentRow().getAttribute("iDate").toString();

If you need some help, be respectful of the forum rules and people will help. By using "urgent" in the title and bumping your message every 2 hours you're just asking to be ignored (which is what you ended up with).

Your urgent help will be very much appreciated
