Help needed: testing webstart JavaHelp examples

Can you break my webstart JavaHelp examples?
<http://www.physci.org/jh/>
These pages (chase the links) represent an attempt to make an Ant based project that will build JWS based examples of JavaHelp, with a view to gaining hosting of the JavaHelp APIs as webstart extensions at the home site (javahelp.dev.java.net).
The deployment needs further refinement and testing, mostly detailed here.
<http://www.physci.org/jh/todo.html#test>
If you can answer any of those questions (them's the things that end with '?'), uncover any (new) bugs, or resolve any of the existing bugs, please speak up.

Help needed in web service example. Thank!!!

Hi,
I tested WebLogic 6.1 message-style web service example. For the
ProducerClient.java example, I tested successfully. But for
the ConsumerClient.java example, I kept getting error messages.
Can any expert offers some explanation or advice? Need to
show my boss the cool thing. Any help is highly appreciated.
Thanks.

Help needed with webstart

hi , I am sorry if i have posted this topic in a different forum,but my application has been done using java swings so i am posting this here..and coming to my problem....
I got a project which is developed with JSDK1.4.2 and using swings and awt.
Till today, if we want to install this application into a computer we are manually copying the JAR Files into the required directories.
Now I got a task to create a Setup equal to Java Web Start. My SE said that I have to create a setup which works like or with Java Web Start.
The idea that he gave is the following.
The source code should be in the server and when ever a user opens java web start it should copy the latest version of the program into the client and run the program to open the application.
As Java web start is installed with JSDK and If I open this I can see some applications which I can open and a desktop icon is being created for every application that I open.
I don't know whether I can include my application too to the Java Web Start or what to do to get the same facility for my project!!!!!
What are the tasks that I should do to realize this and where can I get some literature which is explaining the steps in creating such an automatic Java Web Start setup??????????????????? (These question marks are to say that am a beginning programmer and have so many question marks on this task.)
it could be a great help for me to start my programming life.
Thanks a lot in advance.
I am waiting for your reply.

Using Java Web Start is quite straightforward. However, you will need to understand how your application works, is configured and is deployed to successfully migrate it to JNLP.
The basic steps are as follows:
1) get a Servlet container and web server (e.g. Tomcat)
2) copy all your JARs/configuration for your application into a directory on your web server
3) create a JNLP file describing your application (i.e. name, url, main-class, classpath etc.)
4) tell your web server the correct MIME type mapping for JNLP files (should be already done in recent Tomcat versions)
5) access your JNLP file via a browser
That should be enough to get Java Web Start at least trying to start your application. You'll almost certainly be getting some errors at that point but you can then start addressing those specific issues one at a time.
You should search on the Java site (not just the forums) for Java Web Start and JNLP file syntax to ensure you've got the MIME type mapping setup for your application and have created a valid JNLP file describing your application. It might be a good idea to start by writing a "HelloWorld" application and getting that to download first.
Note that it's not the source code that you put on the web server, it's the binary resources (e.g. JARs) for your application.
Hope this helps.

Help needed to understand an example in livedoc

Hi,
Below is what I pasted from livedoc - an example of using
events. However, since I am new to flex, I don't understand how I
use this. How can I run this example? Thanks!
package {
import flash.display.Sprite;
import flash.display.DisplayObject;
import flash.events.*;
public class KeyBoardEventExample extends Sprite {
private var bgColor:uint = 0x00CCFF;
private var size:uint = 80;
public function KeyBoardEventExample() {
var child:Sprite = new Sprite();
child.graphics.beginFill(bgColor);
child.graphics.drawRect(0, 0, size, size);
child.graphics.endFill();
addChild(child);
stage.focus = child;
child.addEventListener(KeyboardEvent.KEY_DOWN,
keyDownHandler);
child.addEventListener(KeyboardEvent.KEY_UP, keyUpHandler);
private function keyDownHandler(event:KeyboardEvent):void {
trace("keyDownHandler: " + event.keyCode);
trace("ctrlKey: " + event.ctrlKey);
trace("keyLocation: " + event.keyLocation);
trace("shiftKey: " + event.shiftKey);
trace("altKey: " + event.altKey);
private function keyUpHandler(event:KeyboardEvent):void {
trace("keyUpHandler: " + event.keyCode);
}

I wanted to know how I can use these examples to learn. The
livedoc didn't tell how to use the examples. I did understand it is
a class.
So it seems that readers have to build something that import
this class to run and see the result of the example?

Help needed testing a free "killer application"

Applications which turn your phone into a remote control already exist; but they COST, and they only work on phones with IRDA port.
Maybe no more: it's really probable that ANY cellphone with audio play capability can be used as a remote, just spending 1$ to buy a couple of IR leds!
Take a look at this blog post:
http://jumpjack.wordpress.com/2008/05/20/worlds-cheapest-remote-control-replicator-just-1/
The method described there works fine for me using a PC: I connect one led to audio-in to sample the remote, I edit the waveform, then I play it through a couple of IR leds properly connected to audio-out, and I can control my devices!
There's apparently no reason for which same method can't work with a cellphone's audio-out port:

I'm currently having troubles playing WAV format on my phones: any clue about a free application for s60-2nd for this purpose?
Message Edited by jumpjack on 26-May-2008 12:33 PM

P.S.
if you think being able to control your device using your phone is "just a funny thing"... then try thinking that:
- any s60 phone can be easily programmed in python
- any s60 phone can receive SMS
- 160 GB (or more) Personal Video Recorders are available in the market
- an old s60 model costs around 50$
Sum these all together, and you'll get a ***remotely controllable (by SMS) PVR!!!*** ;-)

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">

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

EDI IDOC generation for interface with Vendor software help needed.

EDI IDOC help needed.
We are NOT an EDI shop, but have a project to output data to Sales Force.com
Sales Force requests IDOC output - eg. 810 Outbound Invoice.
We will need to do a historical load of Orders/Quotes/Invoices from the past 2 years.
Is there a function module or series of FM's that are used to generate the E2EDKxxxxx type segments?
I have been testing using the IDOC_OUTPUT_INVOIC and IDOC_OUTPUT_ORDRSP FM's, but they generate segments begining with E1EDKxxxxx.
Basicall we have a report program that the user enteres in the date range of Order/Quotes/Invoices they wish to extract, the the program needs to output a flat file (.txt) on the server which is then picked up by Sales Force.com.
Also, is there a way to have in the Partner Profile a generic Partner under the "Type KU" that can be used for all orders/invoices so I don't have to create a KU Partner Type for each and every Sold-To customer we have?
I am very new to EDI so any help would be greatly appreciated.
Thanks.
Scott.

Hi Scott,
We will need to do a historical load of Orders/Quotes/Invoices from the past 2 years.
I know it's very tempting to use an interface for such loads if you anyhow have to create one. However, often the volume alone speaks against interface usage for such scenarios.
Is there a function module or series of FM's that are used to generate the E2EDKxxxxx type segments? I have been testing using the IDOC_OUTPUT_INVOIC and IDOC_OUTPUT_ORDRSP FM's, but they generate segments begining with E1EDKxxxxx.
Well, the E2* segments basically reflect the external name of the IDoc segment, whereas the function modules you're referring to basically just create an internal version of the IDoc. Once the IDoc framework then passes the IDocs to the partner, the segment names usually (depends on how the IDocs are passed on) get converted to their external name. If there are multiple versions of a segment, then the version number will be appended to the segment name.
Note that IDoc segment definitions are only partially stored in the data dictionary. If you want to see all versions you should always use transaction WE31 to look at segments. There you can also see for example for E1EDK01 the several versions and when you then use in SE37 function module SEGMENT_EXTERNAL_NAME_GET you will see what SAP produces as the external name for segment E1EDK01. This function module is basically the one that handles the segment name translations.
Ignore the comments for subsystem, this is basically an option in SAP to possibly trigger further external tools (e.g. mapping etc.) for handling the outbound IDocs.
Again, the funny thing is that via the WE30 transaction, if i put in INVOIC02 as the Obj. name and see the segments, i can see that E2EDK01 there is a version 005, but if i go to SE11 and put in E2EDK01005 structure line and i get a "not found". We just have up to E2EDK01002.
In the old days SAP used to generate E1, E2 and E3* structures in the data dictionary (SE11). The E1* structure reflected the character type representation of an IDoc segment, whereas the other two (definition and documentation) contained actual references to data elements (e.g. if you used a quantity field). However, in newer releases those dictionary structures (E2* & E3*) are no longer generated, because they're superfluous (meta data defined via WE31 is sufficient).
Cheers, harald

Java Progrramming HELP, Needed Urgently, T hanks

hey guys,
I have this lab I need to be done tomorrow, its been weeks lol of thinking and figuring things out can someone make it work ? Pleaseeeee !
I feel like going out and yelling for help lol I have been trying to figure this out for weeks now.
I am pasting my Lab and My Codes I did so far, And Please I really need this done today at any rate, all help would be kindly appreciated.
A Java program is required that will produce a number of reports based on the data from the Product file. This file contains the product name, cost, quantity and UPC. The file name must be input. Valid data from the file will be loaded into an array.
A menu will provide the following options: (Note there are changes from previous assignment.)
1     Display of all valid product information including extended price and GST including totals sorted by name.
2     Display of all invalid records sorted by name.
3     Search and display a certain product by name.
4     Sort by UPC and use a binary search and display a certain product by UPC. (valid records)
9 Exit.
Processing requirements:
Input the data from a file and load the records into an object array. Use this object array to produce the above reports.
Code a class definition exactly as given in the following UML.
(For specific students: you may code the UPC as an integer but if not numeric throw an exception that is handled in main. Document your choice in your submission).
Product
? Name : String
? UPC : String
? Cost : Real
? Quantity : Integer
+ Product (Name : String, UPC : String, Cost : Real, Quantity : Integer)
+ Calculate Extended Cost() : Real
+ Calculate GST(): Real
Input Record:
Product name: String
UPC: String
Cost: real
Quantity: integer
Output Reports
1. Display of all product information including extended cost and GST including totals of these 3 fields.
Following is a sample of the output required:
************************ Product Cost REPORT ****************************
Product                    Cost Quantity Extended Cost     GST     Total Cost
Diamond Necklace 12345678901x 54,321.99 188 10,212,534.12 510,626.71 10,723,160.83

2. Display of all invalid records and the count.
Following is a sample of the output required:
Invalid UPC Records = 1
Count Record
1          Tiara Diamond, 12345678901x, 36020.00, 2
3. Search and display a certain product by name. Display appropriate message if not found.
Following is a sample of the output required:
Enter product name: CrownJewels
CrownJewels 99999999991x     100,000.00 1 100,000.00 5,000.00 $105,000.00
6. Display the product information sorted by name
Following is a sample of the output required:
************************ Product Cost REPORT ****************************

TOTALS          (complete these values)           xxx           xxx      xxx
Java coding requirements for this assignment
Main methods required
1.     Load array with all records. Display exception messages only for records that have invalid data in any of the fields. Return array of valid records and logical size.
2.     Validate the UPC. Display each report when requested from the menu.
3.     Justify the data in the columns. Right justify numeric fields; left justify the alpha fields.
4.     A method for each report required in the menu.
Class methods
5.     Use the object method for the extended cost.
6.     Use the object method for the GST.
You may use additional methods in the main program but do not add any methods in the class definition.
Use DecimalFormat for rounding.
Create an array to hold the objects. Assume that we only need to process a file of a maximum of 500 records but the file may be larger than 500 records.
A Universal Product Code consists of 12 digits. The first digit (from the left) is the UPC type. The next five digits are the Manufacturer code. The next five digits are the product code which is assigned by the manufacturer. The final digit is the check digit. A person can determine the check digit of a Universal Product Code by doing the following:
Step 1: Sum all of the digits in the odd positions together.
0+4+0+1+5+9 = 19
Step 2: Multiply the sum from Step 1 by 3.
3 * 19 = 57
Step 3: Sum all of the digits in the even positions together.
6+2+0+1+8 = 17
Step 4: Sum together the results from Step 2 and Step 3.
17 + 57 = 74
Step 5: Subtract the sum from the next highest multiple of 10.
80 - 74 = 6 [check digit]
TEST DATA:
Step 1: Create 5 or MORE additional records that will test all conditions. Include these in your documentation. Identify what field is tested in your test data. (Example: error in each field of the record, rounding up, rounding down, valid UPC, invalid UPC, formatting of report, file too large
Step 2: Use the file attached.
GODDDDDDDDDDDDDD lol pasting it made me go crazy,
these are my codes so far, HOwever the problem is ONLY DISPLAY MENU SHOWS, nothing else even though i have enough codes that it can show something,
My codes are as follows:

Any help would be great thanks !!
Take care,

1) It's your problem that you waited until the last minute before you went for help...not ours. We'll give your problem the same attention as anyone elses...therefore your problem isn't any more urgent than any other problem here.
2) I don't intend on doing your entire assignment. Nor do I intend on reading all of it. If you need help with a specific requirement, then post the information/code relevant to that requirement. I don't know how to help you when you bury the problem inside a 9 mile long essay.
3) Post code in tags so it's formatted and readable. (there's a *code* button up above that makes the tags for you).

Help needed with 'while' loop please

Problem: When a non-integer is entered, the console displays "Enter a wager > java.util.InputMismatchException" intermitentlly.
Here is the source codes
===================
import java.util.Scanner;
public class Test {
     private static int bankBalance = 1000;
     public static void main(String []args) {
          System.out.println("You entered: " + wager());
      Ask user for a wager, which must not be greater than 'bankBalance' and
      must be a valid Integer. Continue asking until a valid wager is entered.
     private static int wager() {
          Scanner scanner = new Scanner(System.in);
          int input = bankBalance + 1;
          boolean isValid = false;
          while( (input > 1000) || (isValid == false) ) {
               try {
                    System.out.print("Enter a wager > ");
                    input = scanner.nextInt();
                    isValid = true;
               } catch(java.util.InputMismatchException im_exc) {
                    System.out.println(im_exc.toString());
          return input;
}

It would help if you put aside your code, and wrote out some pseudo-code first so that you understand the steps you will need to take. for example
get input from user
set counter to first number entered
while counter less than/ equal to second number
      check if number is even
           if even, add to even_sum
           else output counter, along with its square
      increment counter by one
end while
output sum of evensthat block, when coded, will solve 3 of the problems, the other 2 will require separate loops
Good Luck

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

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.

Hi all help needed I have a canon 40D. I am thinking of buying a canon 6D.
But not sure that my lenses will work.
I have a 170mm/ 500mm APO Sigma.
A 10/20 ex Sigma HSM IF.
And a 180 APO Sigma Macro or do I have to scrap them and buy others.
ALL Help will be greatly received. Yours BRODIE

In short, I love it. I was going to buy the 5DMark III. After playing with it for a while at my local Fry's store where they put 5DMII, 5DMIII and 6D next to each other, using the same 24-105L lens, I decided to get the 6D and pocket the different for lens later.
I'm upgrading from the 30D. So I think you'll love it. It's a great camera. I have used 5DMII extensively before (borrowing from a close friend).
Funny thing is at first I don't really care about the GPS and Wifi much. I thought they're just marketing-gimmick. But once you have it, it is actually really fun and helpful. For example, I can place the 6D on a long "monopod", then use the app on the phone to control the camera to get some unique perspective on some scenes. It's fun and great. GPS is also nice for travel guy like me.

Urgent help needed on deployment facts

Hi
I had completed a Java Web based application using JApplet, which in turn uses Java Media Framework and Java Communications APIs. So when i deploy this application and let the clients use this application. I need to dump some jar files and properties files into the clients JRE so that all the APIs will work properly. Without any installations. I tried doing this manually by copying these files into client machines So is there a direct method for performing the task. Or i need to add some additional code to my applet so as to find the clients current JRE version and place the required files under using FTP? Can i write a setup routine or something which does all these operations once the client access the applet?
Help needed in the above issues
Thanks in advance

What you will want to do is look into JNLP and Java WebStart. They allow you to write a setup for your product that makes installation as easy as InstallShield™ does for the Windows™ platform (ie: it allows customers who cannot tell Java from Perl to install your product).

URGENT HELP NEEDED ... Tomcat Realm and JRE1.4 plug-in problem

I have tried the Security Realm of Tomcat. Since I do not have
an LDAP server, I decided to use the Tomcat-users.xml file in
Tomcat\conf directory.
I added the following lines of code in the web.xml file.
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>

<role-name>webviewer</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>Tomcat Manager Application</realm-name>
</login-config>
The <role-name> "webviewer" is added into "Tomcat-Users.xml" as the following:
<tomcat-users>
<user name="test" password="password" roles="webviewer" />
</tomcat-users>
So, now when we type the url: http://localhost:8080/adbpdbre/default.htm, TOMCAT shows a dialog box asking for UserName: and Password:Now, only when we give the username and password, it shows the page. This is exactly what we want.
But the problem now is, this default.htm page, has 5 links to 5 applets. The first time that I click on one of these links, the JRE plug of 1.4 shows a dialog again asking for the username and password. Till I dont provide the username and password the system doesnt go ahead and applet doesnt load. I do not want the JRE to ask me for the username/passwords again..How to avoid this ?
Can you give me some more information on this. Ultimately in the production usage, we will be using LDAP and not Tomcat's memory realm.
URGENT HELP NEEDED ... I need to get back to my client on this.
Help would be v. much appreciated.

In the config file, you 're essentially saying that you want Tomcat to prompt for usr/passw on every request (url-pattern = /*) made by a 'webviewer', and that's exactly what Tomcat is doing.
Consider using specific url-patterns & roles for resources to be protected. If for now, all you need is to protect the first page, use a more specific url-pattern.
Just an advice : if you'll be using LDAP in production, do not waste time with Tomcat's Security Realm and the BASIC authentication type, since the two have not much in common. Start reading doc on LDAP, and code a prototype, or even better, a vertical slice of the app (i.e a proof of concept).
