Help with java. Please ASAP I have to submit this in a few HOURS
I just downloaded the new java and I can't compile a test program that I need to complete for class. I was told to save a simple program in the "bin" folder and there isn't one in the "java6 update 2". When I try to compile the program is says "'javac' is not recognized as an internal or external command, operable program, or batch file."
What do I do?
if u use download jdk1.6.0
go to bin folder to compile from command prompt..
or u can use some compiler..
u downloaded it but did u install??

Hi, I'am new to these forums just wondering if someone can help me, my problem is I have a txt file on a web server I have read in using a 'StreamConnection' and 'StringBuffer' converting the data in the txt file to String.
what I am stuck on though is the data holds user names and passwords which I need to validate for login.. I have set up a login form with textfield for userName and Password. If the user name and password match I then need to print out the relevent data from that users field.
Can anyone assist me with this? the fields look like this:
1|johnsmith|js|50|40|67|77|�
.etc. .
cheers,
Andrew.

I got a JAVA is unavailable error message on a site I've been to thousands of times and never had a problem. I went through the discussions and saw an archived post dealing with a similar issue and the person was told to remove all the JAVA files then do the software update to reinstall the JAVA. I followed the advice except now that I have removed all the JAVA files my software update is not recognizing that anything needs updating. Do you guys think that I just missed some files or what could it be? I am not very tech-savvy so detailed answers would help me out a whole lot.
Thanks for your time, I appreciate it a lot!Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find nothing has changed after you complete it.

Help with payments please. I have been charged 4 times.
I bought a monthly Skype package which I have now used all the minutes for. When I tried to add more minutes (the same package as the original) it has charged me 4 times and has not provided with with any minutes. Please help. Thanks
Same thing happen to me yesterday and today. I have been trying to buy because I cannot afford to keep doing the $10 and I call overseas a lot.
PayPal shows that it charged me that one yesterday and today but it did not show in my bank yet (thank God) but I hope it won't charge me all at once.
The customer service is too hard to approach here. It hurts as appropriate supporter.
I think they might have approved technical issues since yesterday. -
PI File adapter has a processing option u2018Empty-Message Handlingu2019 to ignore or Write Empty Files. In case there is no data created after mapping on target side then this option determines whether to write an empty file or not. But there is a catch to this option when it comes to using it with File Content Conversion which is described in SAP Note u2018821267u2019. It states following:
I configure the receiver channel with File content conversion mode and I set the 'Empty Message Handling' option to ignore. Input payload to the receiver channel is generated out of mapping and it does not have any record sets. However, this payload has a root element. Why does file receiver create empty output file with zero byte size in the target directory? Example of such a payload generated from mapping is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<ns1:test xmlns:ns1="http://abcd.com/ab"></ns1:test>
solution :
If the message payload is empty (i.e., zero bytes in size), then File adapter's empty message handling feature does NOT write files into the target directory. On the other hand, if the payload is a valid XML document (as shown in example) that is generated from mapping with just a root element in it, the File Adapter does not treat it as an empty message and accordingly it writes to the target directory. To achieve your objective of not writing files (that have just a single root element) into the target directory, following could be done:
Using a Java or ABAP Mapping in order to restrict the creation of node itself during mapping. (This cannot be achieved via Message Mapping)
Using standard adapter modules to do content conversion first and then write file.
can someone help with java mapping that can be used in this case?Hi,
You have not mentioned the version of PI you are working in. In case you are working with PI 7.1 or above then here is the java mapping code you need to add after message mapping in the same interface mapping

The code for PI 7.0 should also work for PI 7.1 provided you use the right jar files for compilation, but vice-versa is not true.
Could you please let us know if this code was useful to you or not?

I would really appreciate some help with my search & results page that is now throwing up the following error:
Warning: mysql_free_result() expects parameter 1 to be resource, null given in...... line (the line number refers to the following code:
mysql_free_result($RSsearchforsale);
mysql_free_result($RsSearchForSale2);
mysql_free_result($RsSearchForSale3);
mysql_free_result($RsSearchForSale4);
I am new to php and am setting up a dynamic site in Dreamweaver (thanks to the Missing Manual – very helpful). I apologise in advanced for my lengthy description of the problem (perhaps get yourself a drink before continuing!)
I have a Search page with 4 list menus where the user can select an option from ANY or ALL of the menus, if a menu is not selected the value posted to the results page will be 'zzz'.
On the results page I have 4 recordsets, all getting the correct results, only one recordset is required to run depending on how many of the menus from the search page have been selected and a test is run before executing the sql using a SWITCH statement checking how many of the menus had passed the 'zzz' values from the Search page if you see what I mean. The results page has Repeating Regions, Recordset Paging and Display Record Count. The exact result that I require are generated by this method.
THE PROBLEM, when a user makes a selection the first page of 10 results is fine, but the error message above is shown at the bottom of the page, AND when the user clicks NEXT to go to the next page of results THERE ARE NO RESULTS.
This is exactly what happens depending on how many menus selected and which recordset is used:
4 menus selected from Search: runs RSsearchforsale, results correct but 3 error messages on 1st page relating to mysql_free_result($RsSearchForSale2),mysql_free_result($RsSearchForSale3), & mysql_free_result($RsSearchForSale4). The display record count shows correct results found. NEXT page is empty of results and still shows the correct display record count as if it should be displaying the records, also has the same 3 error messages.
3 menus selected from Search: runs RsSearchForSale2, results correct but 3 error messages on 1st page relating to mysql_free_result($RSsearchforsale),mysql_free_result($RsSearchForSale3), & mysql_free_result($RsSearchForSale4). The display record count shows correct number of results. NEXT page shows results from the DEFAULT setting of the recordset and the Display record count reflects this new set of results. Also still shows the 3 mysql_free_results for RsSearchForSale2, 3 and 4.
2 menus selected from Search: runs RsSearchForSale3, results correct but 2 error messages on 1st page relating to mysql_free_result($RSsearchforsale) & mysql_free_result (RsSearchForSale4). The display record count is correct. NEXT page does exactly the same as described in above 3 menus selected.
1 menu selected from search: runs RsSearchForSale4, results correct but 1 error meaasge on 1st page, mysql_free_result($RSsearchforsale). Display record count is correct and again when NEXT page is selected does as described in above where 2 or 3 menus selected.
If you have gotten this far without falling asleep then thank you and well done! I have pasted my code below and I know its a lot to ask but please please can you give me an idea as to where or why I have gone wrong. I felt I was so close at perfecting this search and have been working on it for weeks now. I feel sure the problem is because I have 4 recordsets on the page but I could find no other way to get the exact results I wanted from the menus.
Looking forward to any help.

}?>Hi David,
Thank you for your reply and patience, we are getting closer in spite of me!
Of course i needed to change the name of the recordset, i did that the first time i did it (when i got the error), the when i re did it i forgot, in my defense i was also trying to get a full understanding of the code using the W3Schools php reference and writing by the side of the code on a piece of paper what it meant in English.
Anyway after re doing the code correctly it still displayed all the records of my database but i realised that was because i was POSTING from the search form and when i changed it to the GET method I now get results when all 4 list menus are selected from and the paging works. After reading about the POST / GET method i chose the POST option, is the GET method a better option in my circumstance?
On my site now if the user selects from 1,2 or 3 of the menus rather than selecting the relevant records it displays the NO RESULT page, I would like my users to be able to select from all of the menus or ANY combination of the menus and find exact results for their search, for example if they only select a location and a price i want it display all records that match that location and price with any number of bedrooms and any Type of property: Perhaps this is due to how my list menus are set up, for each menu the first Item label is Location (or Beds or Type or Price) and the value i have left blank which i believe means that it will use the item label as the value, the second Item label for all menus is Any and again the value has been left blank. All other item labels have values relevant to database records.
I do look forward to your reply and cannot thank you enough for following this through with me, please continue to bare with me just a little more,
best regards
Tessimon

You're not adding the WHERE clause to the SQL query. My example code uses $query_search. You need to change that variable to match the name of your recordset, i.e. $query_RSsearchforsale.
Moreover, the WHERE clause needs to go before ORDER BY.
$query_RSsearchforsale = "SELECT trueprice,`desc`, `propid`, `bathrooms`, `location`, `type`, `price`, `beds`, `photo1`, locationtable.loc, typetable.style, bedtable.`number` FROM detailstable JOIN locationtable ON detailstable.location=locationtable.locid JOIN typetable ON detailstable.type=typetable.typeid JOIN pricetable ON detailstable.price=pricetable.priceid JOIN bedtable ON detailstable.beds=bedtable.bedid ";
// Set a flag to indicate whether the query has a WHERE clause
$where = false;
// Loop through the associatiave array of expected search values
foreach ($expected as $var => $type) {
if (isset($_GET[$var])) {
$value = trim(urldecode($_GET[$var]));
if (!empty($value)) {
// Check if the value begins with > or <
// If so, use it as the operator, and extract the value
if ($value[0] == '>' || $value[0] == '<') {
$operator = $value[0];
$value = ltrim(substr($value, 1));
} elseif (strtolower($type) != 'like') {
$operator = '=';
// Check if the WHERE clause has been added yet
if ($where) {
$query_RSsearchforsale .= ' AND ';
} else {
$query_RSsearchforsale .= ' WHERE ';
$where = true;
// Build the SQL query using the right operator and data type
$type = strtolower($type);
switch($type) {
case 'like':
$query_RSsearchforsale .= "`$var` LIKE " . GetSQLValueString('%' .
$value . '%', "text");
break;
case 'int':
case 'double':
case 'date':
$query_RSsearchforsale .= "`$var` $operator " .
GetSQLValueString($value, "$type");
break;
default:
$query_RSsearchforsale .= "`$var` = " . GetSQLValueString($value,
"$type");
$query_RSsearchforsale .= ' ORDER BY detailstable.trueprice ASC';

Be grateful for your help with Photoshop Elements which I have been using for several years.
Be grateful for your help with Photoshop Elements which I have been using for several years. Does Elements need to have access to ‘My Pictures’ on Windows as when I remove Photos from ‘My Pictures’, Elements later, when backing up, gives a message that it is unable to ‘reconnect’ to the same picture on elements. On other occasions when removing a photo from Elements catalogue I also get a similar message when backing up saying ‘unable to reconnect’. 1. Is there a relationship between Elements and My Pictures and is Elements dependant on the Windows ‘My Pictures’? 2. Why does some photos in Elements in some cases cause them to multiply e.g. double; triple; quadruple; and on occasions even more? Is there something I need to do to stop this or an easy way I can remove the multiples without spending hours doing it manually one by one? Am I doing something wrong? My O/S is Windows XP SP2 and windows Vista on my Laptop. I have been using Elements 5 and have just purchased Photoshop Elements 8.0. (Upgrade) and about to install it. Be grateful for any advice as I do enjoy using the program if only I can resolve this issue. I am not a PC wiz and mainly use Elements to catalogue photos from which I compile collections and from them slide shows with music. Any advice appreciated Sonny.t PS Have tried to post this previously but without success so hoping to see message appear and a +response
The organizer doesn't care where you send your photos when you download them via the downloader or where they happen to be when you first bring them in if you use the Get Photos command, but once your pics are in the Organizer, you *must* move them from within organizer or it can't find them. You don't have to use My Pictures at all if you don't want to, but regardless of the folder where you put your photos, if you want them someplace else, you use organizer to do it.

Urgent help. I have upgraded my phone but every few hours the apple appears and stays for 15 min an hour or more?
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
If the issue persists, take the device to Apple for evaluation. -
When i'm trying to send an application as gift using "send gift via email" option, it is not allowing me to buy the app. A pop up appears with message "Please contact itunes support to complete this purchase"
Okay, so do as it says, contact iTunes customer support.

Need help with Java, have a few questions about my Applet
Purpose of the program: To create a mortgage calculator that will allow the user to input the loan principal then select 1 of 3 choices from a combo-box (7 years @ 5.35%, 15 years @ 5.50%, 30 years @ 5.75%).
Problem: My program was working properly (so I thought). I can get the program to properly compile and run through TextPad. However, I noticed that when the user clicks the calculate more than once (with the same input), it slightly alters the output calculations. So that is my first question, Why is it doing that? How can I get it only calculate that information once unless the user changes it etc?
My next question is regarding my exit button. I was told by my instructor (who has already stated he won't help any of us) that my exit button does not work for an applet and only for an application. So, how can I create an exit button that will work with an applet? I thought I did it right but I can't find any resources online for this.
Next question, why isn't my program properly validating invalid input? My program should only allow numeric input and nothing more.
And last question, when invalid input is entered and the user clicks calculate, why isn't my JOptionPane window for error messages not displaying?
I know my code is a little long so I have to post this in two messages. Please don't criticize me for what I am doing, that is why I am learning and have come to this forum for help. Thanks

The assignment is:
Create a Java program to read in an unknown number of lines from a data file. You will need to create the data file. The contents of the file can be found at the bottom of this document. This file contains a football team's name, the number of games they have won, and the number of games they have lost.
Your program should accomplish the following tasks:
1. Process all data until it reaches the end-of-file. Calculate the win percentage for each team.
2. Output to a file ("top.txt") a listing of all teams with a win percentage greater than .500. This file should contain the team name and the win percentage.
3. Output to a file ("bottom.txt") a listing of all teams with a win percentage of .500 or lower. This file should contain the team name and the win percentage.
4. Count and print to the screen the number of teams with a record greater then .500 and the number of teams with a record of .500 and below, each appropriately labeled.
5. Output in a message box: the team with the highest win percentage and the team with the lowest win percentage, each appropriately labeled. If there is a tie for the highest win percentage or a tie for the lowest win percentage, you must output all of the teams.

Help with java translator...PLEASE!!!

i am having real problems tackling a question about programming a translator, can anyone help with this question?
- Write a Java class 'German' to model the german dictionary(using only a few phrases, say 4-5). You will need to choose an appropriate representation for the constant dictionary(ignore accents etc), and to provide a method 'Translate' that, given an English phrase, returns the corresponding German phrase. You must also deal with phrases that are not available.
I hope someone can help...

Sreaming at the top of my lungs for HELP with Java Script problem!
Hello,
I have this strange problem that no one seems to know why or how to fix it.Whenever I encounter a web site that has java scripting for anything pop ups or redirects to url's anything that says java script when I mouse over the link my browsers do nothing.That is for explorer 6.0 beta netscape 4.7 and netscape version 6.I have tried in another forum some suggestions but nothing changed even though I am told nothing is wrong with the java scripting.I used to be able to click java script's with all of these browsers but no longer.That was a few months ago.Now to try something new I tried to see if a new browser would work.I now have the latest version of Opera.It did work but using Opera on some sites limits what I can do so it doesn't solve my problem.Then I tried the Sun JavaHot browser it also worked but limits what I can do on some site's.I have Windows 98 & updated most of my dll's etc & my java is version 2 1.3.1.My java script is enabled in Explorer & netscape's & the security is at a minimum level.Please help me figure out why these other browsers work but the other's do not.I want to edit a web site of mine but I can't because of this problem.I am very frustrated by this and need as detailed help as I can get.Anything of a suggestion would be very much appreciated.But I am also not an expert on the working's of a computer so bear with me.
BrianHi,
Well I am thinking that if anyone could know something about Java script it would be java developers.But anyways I had the previous version of explorer 5.0 & the java didn't work in it either.Now how weird is this,I opened netscape 4.7 today & the java scripts are suddenly working.This has me scratching my head wondering if my computer is possesed by some force beyond my capability to know...????Weird as it seems though the explorer still will not respond to a java script.
