VB Programmer needs java help
I am a VB programmer and have started to learn Java a little bit. I need this program to be written anytime by Monday, but it must be written in java because they plan to use it on multiple platforms. Our java programmer quit and I don't know enough to write it in java. The program is to figure payroll. The user will input their name and remove the check in the hourly check box if they are salaried. If the employee is hourly, then any hours worked over 40 are time and a half. If they are salaried, they must choose what company level they are. I have included the three salary levels below. The program then needs to print to the screen in the bottom text box their yearly salary computed for a 40 hour work week. Can anyone help me and write the program? Whoever will do this for me, I will award 34 duke dollars. That is all I have.
Thank you so much for your help,
Kori

I am a VB programmer and have started to learn Java a
little bit. I need this program to be written anytime
by Monday, but it must be written in java because they
plan to use it on multiple platforms.Do this this little toy program in VB so you have a working solution on one platform by Monday. Show it to your boss and say you did a rapid prototype first for people to evaluate. Then take your time and convert it to Java.

Oracle developer needs Java help
I develop applications in Oracle 8i on NT4. As part of a trigger, I need to perform an update to an extremely large table which takes many minutes. Because it's tied to a web page, I can't wait for the update to complete. Oracle natively doesn't support system calls -- I use the Shell() command in VB -- but Oracle DOES support Java stored procedures. I'm hoping that a Java stored procedure will be able to spawn/execute a new process/program specified by a command line instruction (ie: "C:\SQLPLUS.EXE SCOTT/TIGER @update.sql") and return immediately - without waiting for the process to complete. There doesn't need to be any handle for or call back from the process - just fire and forget. Can anyone provide me some direction, or better some existing Java code that does this? THANKS!
Hi "todmcg",
I'm not sure that I have understood your question correctly, but here goes anyway...
Yes you can create a java stored procedure and have a trigger execute that procedure. In order to execute system commands in java, you usually use the "exec()" method of class "java.lang.Runtime". It is also easy to spawn new threads using java. So yes, you can have your java stored procedure execute a system command in a background thread.
In my opinion, the Oracle documentation explains very well how to create a java stored procedure. The documentation is available from:
http://tahiti.oracle.com
Also, examples of how to call system commands from java stored procedures are available at this Web site:
http://asktom.oracle.com
You may also find relevant information at:
http://metalink.oracle.com
and
http://technet.oracle.com
Of-course, you can also use JDBC from your java stored procedure to execute your "update.sql" script -- without the need to execute a system command.
Basic code skeleton:
[NOTE: Untested and may contain syntax errors.]
public class SystemCommand implements Runnable {
private static String cmd;
public void run() {
Runtime runtime = Runtime.getRuntime();
runtime.exec(cmd);
public static void execCommand(String cmd) {
this.cmd = cmd;
new Thread(new SystemCommand()).start();
}Hope this helps you.
Good Luck,

Ive never visited a Java forum other than this one and its been over 2 years now. Out of curiosity I just went to JavaRanch.
Ive seen a lot of heated flaming from both sides (on these forums)
but i figured id take a look today.
The FIRST post i look at someone asks what the purpose of an
interface is and one of the responses he gets is:
"Please revise your display name to meet the JavaRanch Naming Policy. To maintain the friendly atmosphere here at the ranch, we like folks to use real (or at least real-looking) names, with a first and a last name.
You can edit your display name here. Thank you for your prompt attention!"
i wish i could go to 33 pt font: WTF IS THAT?
WEIRD!
Thats just way to creepy for me and im out... as if the brown and the
meesen (brian regan joke) everywhere werent enough.
Anyone know any other good ones?
http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=33&t=019908JavaRanch scares me as well. Yea i think the ranch is making an army of cattle.
Ill check out devshed.

SO F*CKING SCARY:
"I understand that in some cultures there is no such thing as "first name and last name" - there is just one name. If you are one of these people, I WOULD LIKE TO HUMBLY ASK YOU TO SACRIFICE A PIECE OF YOUR CULTURE to help me build this culture."
apparently the cows love the policy though:

Hi,
I have used Captivate for a while, but have no idea where to
begin to insert JavaScript into Captivate. Everyone talks about it,
but I can't find a very basic beginner explanation for this. I
don't even know WHERE to put the JavaScript.Dear Altruistic
Thanks for the link to the Netbeans quickstart webpage sadly it does not contain any visual cues as to what proceedures are neccessary to implement the instructions.
For someone like me ( learning disability) this can cause difficulties I learn in a slightly different way to those who are able to assimilate written instructions.
The text might as well have been ancient Greek ...
I really need a discriptive walk through lets give an exampleso you will understand my needs ... say I wanted to open a Microsoft word document on the desktop of a windows PC (ok not a good choice but there you are ) here is how I would begin to write the proceedure
1. look at the bottom left hand side of your screen
can you see a windows symbol with start displayed ?
yes ..
Hold your mouse over the start icon and left click .. then use the cascading menu feature to select office 2003 ...
Do you get the general idea about what I need here ....?
So have a look at the link on my original post that points to David Eck's website where he lists some Java source code and if possible give me the proceedure of how to run this from within the Netbeans environment.
Once I can do this I will be able to teach myself ....
I guess in a nutshell what I am saying is why on earth is their not just a simple feature on the GUI that allows you to import some code and for Netbeans to run in Demo mode ! I know their is sample projects included within the application but here again this does not solve my problem of notbeing able to find a way to run source code from the application.
I hope this makes sense ! -
hi, i hope this is the right place to put this question. i have a optiplex gxi with a 3geg. hardrive. and 64mb of ram.with windows me. when i download java to play on pogo the games will load but they drag and freeze up. the only java download i can get is jre 5.0 update 16 i think i have uninstalled it compleatly.because i keep getting all kinds of errors one i get is ie6 will hang and i get a send to microsoft error report. when i try to update java i get an error number 1723 windows installer error. i can not update the windows installer or even download net framework. please can someone help. (i miss pogo) i have tried to install msjvm but that doesn't work either. sorry for my typeing skills i hope you can help thank you.

thank you for your reply however my computer is not compatable with ie7 i have windows me. whice is not supported. and i can not download java so therefore i have no java installed. any help would be gratefull.That ME based system is beyond it's life span at this point in time. You can use JRE's that were developed about that time--Up to 1.4x (I think, you may get away with early 5).
So basically you have to face reality--that OS, machine, and JVM's have fallen off the grid for the most current games.
If you have completely uninstalled Java, then run regclean several times and then load the last usable version of Java that you have had installed in the past--and realize, the newer stuff is not made for that era of machine. -

I'm lost when I try to figure out what exaclty is Java.... I need your help
Hi, I know that java is OOP, Multiplatform, etc, etc...
But when I try to look on google for jobs about java or "learn Java" what "Should I know in java"... I always found... whebshpere, oracle, linux, jboss, glassfish, opensolaris, struts, hibernate, spring, eclipse, netbeans, jidea, and so on!!!...
I'm lost... I will be sincere ...
I've started thank for a friend in a world of programming with .NET (ASP.NET SQL .NET Silverlight Windows Server) and was good BUT i feel inside that I prefer Java.
I don't know why but with java I feel free, i think will be a good technology for a long time.
But some things make my crazy.
I cant found a fast path or the right path without getting mess. Like I posted above.
So I need your help, if You are an advance programmer... tell what Should I learn ( essencially ) to get a good job. Oracle + Java ? linux + oracle + java? websphere + java? eclipse or netbeans?? all thouse things are awesome... but I am a HUMAN... I can't learn thouse all things and less in little time.... I just want to have a good preparation for to start to look a job in early time.
I look forward yours answers.

Urgent help needed(java frames)

MarinaHi,
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.

can someone pls help me with java on my macbook pro because after i download the mountain lion java has died and i need java to see streaming quotes from stock market
Java is no longer included in Mac OS X by default. If you want Java, you will have to install it.
However, note that you should think twice before installing Java for such a trivial need as looking at stock market quotes. There are other ways to get that information that don't involve Java, and using Java in your web browser is a HUGE security risk right now. Java has been vulnerable to attack almost constantly for the last year, and has become a very popular, frequently used method for getting malware installed via "drive-by downloads." You really, truly don't want to be using it. See:
Java is vulnerable… Again?!

Complete Java n00b...need some help
I'm very new to Java and I need some help writing a basic program.
I need to write a program that lets the user add up an infinite amount of floating point numbers. The program should compute the sum of all the numbers entered thus far. So for example if the user enters 2 and 3, it should give a number of 5. If the user then enters 4, I should give me 9 etc.
I'm not really sure how to get started on writing that. I can add up two numbers but I don't know how to tell the program to keep adding additional numbers to that sum. Can someone please help me out? thanksIt's ok... it can be hard to understand even the simplest concepts with only text and no help.
There needs to be an int variable outside (before) the loop initialized to 0.
float num = 0;Next, you need to have an infinite loop that requests floats to add onto the number.
Scanner input = new Scanner(System.in);
while (true) {
float toAdd = input.nextFloat();
num += toAdd;
System.out.println("Current sum " + num);
}Putting all this together and putting it into a main method will work, but we have a bit of an issue. The program won't stop! For that reason, we need to specify a number which can exit the program. I like to use 0 for this purpose.
Scanner input = new Scanner(System.in);
while (true) {
float toAdd = input.nextFloat();
if (toAdd == 0) { //test if toAdd is 0 so the program can break;
break;
num += toAdd;
System.out.println("Current sum " + num);
}So, this code will work:
import java.util.Scanner;
class AddNumbers {
public static void main(String[] args) {
float num = 0;
Scanner input = new Scanner(System.in);
while (true) {
float toAdd = input.nextFloat();
if (toAdd == 0) { //test if toAdd is 0 so the program can break;
break;
num += toAdd;
System.out.println("Current sum: " + num);

Beginner in java and need your help about DES
hello,
I m a new guy in java programming and learn from many books.I m making a website and portal right now and dying need your help about DES.my portal (using java) requires somebody to make a login name and a password.I m done with the server and client things and rite now stuck with this "DES" stuff.
so I make some conditions and algorithm below..
1. when a user login,the password is encrypted.at this point,cleartext(id) and encryption (M,N) are involve.
2. then the key is changed based on algorithm.
3.the key changed by key(id) is received and the original text should be encrypted.
the algorithm
1. the original text x1.x2.x3.x4.x5.x6.x7.x8 (64 bits)
2. encypt the password
a. Each character is changed into an int type by the ASCII code, and let the 1st bit be an odd number parity bit.
b.The 1st bit of the 1st character in (IP) is set to '1', and the 8th bit of the 8th character as '64'.
c.the rest (IP) is like this
1 2 3 4 5 6 7 8
0 # 58 50 42 34 26 18 10 2
8 # 60 52 44 36 28 20 12 4
16 # 62 54 46 38 30 22 14 6

e. key y1,y2,y3,y4,y5,y6,y7,y8 (64bit)
f. generate the key based on ID
a. Each character is changed into an int type by the ASCII code, and let the 1st bit be an even number parity bit.
b.the process is repeat again.
anybody has an idea to help me with the sample program?
thanks in advance...just ask about a simple program how to receive a
password from somebody and change it to a key..and
then confirm it with DES.Once again I have a problem understanding what you are asking.
Are you trying to use the password as a key to encrypt some 'standard thing' and place this encrypted value in a database? If so then look in the JCE for 'password based encryption' such as PBEWithMD5AndDes. This seems back to front to me but I can see nothing wrong with the approach since the 'standard thing' you would encrypt is in effect a key. If this is for a commercial application then I would find a security expert to evaluate your proposal!
In my experience it is more normal to encrypt the user's password with DES and store the result in the database. To do this just look in the JCE for DES encryption and consider using DES with CBC and PKCS5 padding. Also, consider encrypting the concatenation of the user's 'user name' with the password as this will (almost certainly) avoid having two encrypted values in the database that are the same even if two users have the same password.
For both of these you might consider using Base64 or Hex to turn you encrpted bytes into ASCII characters before trying to store them in your DB. -
Since installing Mac OS 10.10.1 photoshop will not run, it will not launch. A window indicates that it needs JAVA SE6 to run. JAVA SE6 is installed. I have re-installed and restarted but photoshop will not run and I get the same message window that I need to install JAVA SE6. How do I make this work?
Have you added any Photoshop Add-on that uses an external JavaScript. Photoshop itself has is own ScriptingSupport Plug-in and does not use an external java. Also Java SE6 is old and has security issues you should update to version SE8
Note the plug-in is system info

Java Error in RFC Lookup in XSLT Mapping usinf Java helper class
Hi All,
I am doing RFC Lookup in XSLT Mapping using Java Helper class.
The Lookup works fine when called one RFC at a time However my requirement is I want to do 2 Lookups.
Both Lookups works when done individually however when I call both lookups in one mapping I get following error "javax.xml.transform.TransformerException: DOMSource whose Node is null."
Following is the code I have written in XSLT for the lookup:
<xsl:template name="Lookup_1">
<xsl:param name="STDPN"/>
<rfc:RFC_READ_TABLE>
<QUERY_TABLE>KNA1</QUERY_TABLE>
<OPTIONS><item><TEXT>
<xsl:value-of select="$STDPN"/>
</TEXT></item>
</OPTIONS>
<FIELDS>
<item>
<FIELDNAME>KUNNR</FIELDNAME>
</item>
</FIELDS>
</rfc:RFC_READ_TABLE>
</xsl:variable>
<xsl:variable name="response" xmlns:lookup="java:urn.mt.pi" select="lookup:execute($request, 'BS_D, 'cc_RfcLookup', $inputparam)"/>
<xsl:element name="STDPN">
<xsl:value-of select="$response//DATA/item/WA"/>
</xsl:element>
</xsl:template>
<xsl:template name="Lookup_2">
<xsl:param name="BELNR"/>
<xsl:variable name="Query">AGMNT = '<xsl:value-of select="$BELNR"/>'</xsl:variable>
<xsl:variable name="request1">
<rfc:RFC_READ_TABLE>
<QUERY_TABLE>ZTABLE</QUERY_TABLE>
<OPTIONS><item><TEXT>
<xsl:value-of select="$Query"/>
</TEXT></item>
</OPTIONS>
<FIELDS>
<item>
<FIELDNAME>KUNAG</FIELDNAME>
</item>
</FIELDS>
</rfc:RFC_READ_TABLE>
</xsl:variable>
<xsl:variable name="response1" xmlns:lookup="java:urn.mt.pi" select="lookup:execute($request1, 'BS_D','cc_RfcLookup', $inputparam)"/>
<xsl:element name="BELNR">
<xsl:value-of select="$response1//DATA/item/WA"/>
</xsl:element>
</xsl:template>
My Question: Am I doing anything wrong? Or Is it possible to call multiple lookups in one XSLT?
Thanks and Regards,
AtulHi Atul,
I had the same problem like you had.
The main Problem is that with the example code the request variable is created as NodeList object. In XSLT a variable is somekind of a constant and can't be changed. As the request object is empty after the first request the programm fails at the following line:
Source source = new DOMSource(request.item(0));
So I've created a workaround for this problem.
In the call of the template I've put the request as a parameter object at the template call:
<xsl:with-param name="req">
<rfc:PLM_EXPLORE_BILL_OF_MATERIAL xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
<APPLICATION>Z001</APPLICATION>
<FLAG_NEW_EXPLOSION>X</FLAG_NEW_EXPLOSION>
<MATERIALNUMBER><xsl:value-of select="value"/></MATERIALNUMBER>
<PLANT>FSD0</PLANT>
<VALIDFROM><xsl:value-of select="//Recordset/Row[name='DTM-031']/value"/></VALIDFROM>
<BOMITEM_DATA/>
</rfc:PLM_EXPLORE_BILL_OF_MATERIAL>
</xsl:with-param>
With this change the request will be provided as a String object and not as a NodeList object.
Afterwards the RfcLookup.java has to be changed to the following:

Then you need to compile and upload this class and it should work.
I hope that this helps you.

and for these programs, also i want help for:
They have errors and i cant fix'em
the commands that i've leaned:
If statements, for loops, while loops,do while, strings, math classes, swithc statement, else if,logical operators,methods, one and two dimensional arrays.
Thanx in advance,

By the way im using Ready to program for the programming.You can't really believe that his brother did this
for him...I did miss that copyright line at the beginning when
I first looked it over, but you know, if it had been
his brother, I'd be kinda impressed. This wasn't a
25 line program. It actually would have required
SOME thought. I doubt my brother woulda done that
for me (notwithstanding the fact that I wouldn't need
help for that program, and my brother isn't a
programmer).I originally missed the comments at the top but when I saw the complexity of what was written then I knew that it was too advanced for a beginner and I relooked through the code and saw the comments.
