Need help in netweaver(java)
Hi everyone,
I'm currently, i'm currently working on java, i want to lean SAP net weaver. probly application development -java.
so can you help regarding this by suggesting books and links so that i can go through and lean it!
Regards
rohith
Hi rohith,
Areas of JAVA in SAP.
1. WebDynpro JAVA.
2. Portal Development.
3. JCo ( JAVA Connector: To connect SAP and JAVA Applications)
But only java in SAP is not sufficient.
You need to know ABAP Programming Language which is a very basic in SAP. It is a back bone of SAP.
For Books i recommend the SAP Books for the relevant topics. For a eagle eye view go search and read the documents in http://help.sap.com
Hope it helps.
Regards,

Need help to handle java FX stuffs...........??
i am very much new to Java FX i want to do a login acceptance and rejection operation.like ::
client will click on the button it will open up the window of created by java FX which will give the login screen*(in this case i would like to mention one thing i all ready have a page like usercheck.jsp which is checking if the user is already loged in or not so need to call this JAVA FX window from that page.)*.This java FX window should have a text field and a password field to match with database.it will show a progressber while it is matching the user name password with database.If the login is correct it will give the user the session stuff and allow him to access**(ie.it will be forworded to the page say,cart.jsp)** otherwise it will give a alert message "login faild".any idea about it..............what should i do now???my database is in access and it connected to my program by DA.java.please guide me what should i do,step by step?and consulting with [http://jfx.wikia.com/wiki/SwingComponents]
now guide me.............
i have just created a swing button say "click me to login" on a UNDECORATED window............so what next.........

Need help writing a Java rule in PDF Forms
I have created an invoice for my contractors via "forms", and in turn made each cell either a drop down list or "read only" field so they cannot change the rate of pay, etc. Here is my issue...My first drop down cell is titled "Job Description". When the contractor selects one of the 8 dropdown options within the Job Description field, I would like it to automatically fill in the hourly rate that is associated with that particular job description (or skill). I currently have my "rate" cell as a drop down, and I want to make that a read only, and when you select the A1 position from Job Description, it will populate the "rate" field with the appropriate amount for that A1 rate. I believe this can be done with writing some Java script, but I have never played with Java and I don't really have the time to teach myself. If anyone can help with me a quick tutorial, or even the formula I should use, so that I can just plug and play, that would be super helpful. If this is a time consuming issue, I would be interested in paying someone to do it for me. Thank you!
Hi George,
I was able to copy my data over to a fresh document, and now it works just fine....thank you so much for your insight and help!
I have another question if you have a moment.
I am trying to do a simple calculation of start time and end time for my employees. Do I need to do this via a javascript, and if so, what area in properties of the result field should I copy it to? for the purpose of the script, the fields are as follows:
DataField1 = start time
DataField2 = end time
DataField3 = total time
I would like to use the h:MM tt format for my time fields if possible.
I've attached a link to the file through my dropbox account, and you'll notice that I created three new fields at the top of the invoice just to test the time calculations before i mock up the whole document.

Any help you can give me would awesome!
Thank you!! -
Need Help with a JAVA programming assignment
How do I write a JAVA program that could be used as the start of an MS-DOS/Windows simulation of the IEEE 802.3 protocol? I am to only code the parts necessary to build the 802.3 frame. For the initial implementation, the Checksum function need not be a CRC function, and the Destination and Source addresses wil be in input, stored, and output, and in dotted-decimal format.
I need:
1. A record to describe the frame, with each field being a (byte-) string of the required size, except that the Data field is of variable size. Although the "Source address" and "Destination address" would be 6 bytes for a real implementation, for this first implementation you can either assume they'll be text strings in the usual "dotted decimal" form (e.g. "14.04.05.18.01.25" as a typical example--from Tanenbaum, p. 429), or 6 hex digits.
2. Suitable constant declarations for values such as the standard "Preamble" and "Start of Frame" values.
3. Suitable functions to Get the three variable values "Destination address", "Source address", and "Data" from the standard input device.
4. A suitable function to display each of the fields of a given frame in a format such as:
Preamble: ...
StartofFrame: ...
Destination: ...
etc.
5. A suitable function to generate a "Pad" field if necessary.
6. A "dummy" Checksum-generating function which just takes the first 32 bits (4 bytes) of the Data (or Data+Pad, if necessary) rather than an actual CRC algorithm.
I have no experience with Java. Can you help me or start me in the right direction?
Thanks...........TKIf you have no experience with Java, then it seems to me your first step should be to start learning the language. But it's difficult to advise how, since we don't know anything about your background. There are many good books available on Java, some are for beginners and some are for advanced programmers, so I'd suggest you go somewhere that has a large selection and start looking for something that doesn't seem completely over your head.

Need help for downloading java at mac book retina
i want to download java at my mac book pro retina but everytime we downloaded its not working..i need this because im going to use it to open my bank account...everytime i gonna check my bank account i need to use another computer not this my mac.why?? can you help me please.
Banks do NOT use Java-in-a-Browser for anything, at all. If you have received a suggestion to conduct banking with JAVA enabled in your Browser, someone is attempting to commit a crime, with you as the intended victim. You are being scammed and should report it to the Police.

I want to control a Vrml Model through Java applet or Java 3D,I try some methods,but none of them work well.
I edited my source code in UltraEdit,and compiled it under command line,in my classpath,I had added the vrml97.jar,so I compiled it successful,but when I run it,it cause a exception"NoClassDefException",what should I do?
So I changed my method,I used another "jar" file provided by cosmoplayer,a Vrml Browser,to control my model,as example in the web,I complied it successful,but when I run it through IE,it still cause some exceptions,even when I try the example provided by cosmoplayer itself,it also give me some wrong information just like this:
Loading Script Node class http://foo.co.jp/Example1.class
# Could not load the script class http://foo.co.jp/Example1.class.
# Please make sure the class is declared PUBLIC or the class file exists.
but this class file is on that path properly! I was puzzled
with this for a long time.by the way,all the document in the web only write the source file like this:
import vrml.*;but I can't found this package,so I renamed the nocosmop21.jar into vrml.jar.and put it in the classpath,but I think this is not the correct way,it must cause a lot of trouble.So if I want use the jar provided with cosmoplayer,what should I do?Did you install Vrml97.jar in your JRE's ext folder (so it will be used in running your applet) as well as you SDK's folder (so that it can be used in the compile)?
Check out the link shown below where I've worked with another person who had similar problem -- while I was able to finally helped that person, it turned out that I wasn't too succesful myself simply because I was using SDK1.3.1.
http://forum.java.sun.com/thread.jsp?forum=37&thread=231662
The problem with using vrml in an applet is that if you need to read a .wrl file from the local disk with the vrml class loader, you run into two security violations: runtime permission to use the class loader and i/o permission to read the local disk file. The URL that I posted in the link shown above is still active and you can try to run this self-signed applet to see if it works for you.

Need help in interfacing Java and MSMQ.
Dear Java Guru,
I am migrating my application from Microsoft Visual Basic to Sun's Java. All the presentation, logic and data layers are already done in Java but we need to retain MSMQ feature as our application server and browsers are using Microsoft OS.
I have check with Microsoft newsgroups and the sample program and libraries they provide requires the use of VJ++. But I do not want to use VJ++ as I am using pure Java. I would be grateful if you can provide me some sample program and the libraries that I need to include in my classpath. Please advise how to interface Sun's Java to MSMQ in this context and any documentation will be helpful.
URGENT !
Regards,
yckok.Hi,
to use MSMQ in java you should embed MSMQ ActiveX in your java application, which gets messages from one queue type and transfer to another type. If you get my freeware API njawin (njawin11.zip) at http://www.simtel.net/pub/winnt/java/ you will find there an example with MSMQ COM control.

I'm just learning java and my teacer likes giving us tests on stuff he never taught us... I'm not asking for you to give me ther answers but just at least explain what this stuff means
he gave us a program then 16 questions about it
All I know is that the prgram is a class that takes students names and test scores and finds there averges and studd like that
ok heres the program
// Solution 5.1
/* Student.java
Manage a student's name and three test scores.
public class Student {
//Instance variables
//Each student object has a name and three test scores
private String name; //Student name
private int test1; //Score on test 1
private int test2; //Score on test 2
private int test3; //Score on test 3
// Default constructor -- initialize name to the empty string and
// the test scores to zero
public Student() {
name = "";
test1 = 0;
test2 = 0;
test3 = 0;
//Aditional constructor -- initialize the name and test scores
//to the values provided
public Student(String nm, int t1, int t2, int t3){
name = nm;
test1 = t1;
test2 = t2;
test3 = t3;
//Aditional constructor -- initialize the name and test scores
//to match those in perameter s.
public Student(Student s){
name = s.name;
test1 = s.test1;
test2 = s.test2;
test3 = s.test3;
//Other Methods
public void setName (String nm){
//Set a students name
name = nm;
public String getName(){
//Get a students name
return name;
public void setScore (int i, int score){
//Set test i to score
if (i == 1) test1 = score;
else if (i == 2) test2 = score;
else test3 = score;
public int getScore (int i){
//retrieve score i
if (i == 1) return test1;
else if (i == 2) return test2;
else return tes3;
public int getAverage(){
//compute and return the average
int average;
average = (int) Math.round((test1 + test2 + test3) / 3.0);
return average
public int getHighscore(){
//determine and return the highest score
int highScore;
highscore = test1;
if (test2 > highscore) highscore = test 2;
if (test3 > highscore) highscore = test 3;
return highscore;
public String toString(){
//Construct and return a string representation of the student
string str;
str = "Name: " + name + "\n" + // "\n" denotes a newline
"Test 1: " + test1 + "\n" +
"Test 2: " + test2 + "\n" +
"Test 3: " + test3 + "\n" +
"Average: " + getAverage();
return string;
Ok so theres the prgram the Questions are:
1. Identify the four structural elements of the student class prgram
2. Why did I omit the clause extends <some class> in my program
3. Explain Class hierarchy
4. Why are instance variables always declared to be private
5. What would happen if I declared them public
6. What happens if I omit it completely
7. Identify the instance variables in student class program
8. What does the constructor method do in the student class
9. Why didn't I declare and intalize my variables at the same time
10. Why do I use so many comments in this program
(I actually know the answer to this one)
11. Why do I need a default constructor
(what the crap is a constructor?)
12. Why did I provide additional constructors
13. In Additional constructor section, explain the following code:
name = "";
name = nm;
14. Explain Chaining and where did I place it in the student class program
15. List 2 visibility modifiers in this program
16 Rewrite the student class to exclude the "\n" in t the toString section
And that is it. I seriously don't know what any of those questions mean PLEASE HELP!A duplicate of this is here http://forum.java.sun.com/thread.jspa?threadID=5141024

Need help with error java.lang.IllegalArgumentException: timestamp on bar b
My company uses Java based applications for real time streaming stock market information and I have come across 2 users that are generating the same error:
Bar.addBar failed adding com.abwg.bar.BasicBar 20071210-08:27:00.000 104.34 104.35 104.25 104.25 950 to com.abwg.bar.BasicBar 20071210-09:30:00.000 104.11 104.38 104.11 104.38 436 :java.lang.IllegalArgumentException: timestamp on bar being combined older than original bar
I have had no luck trying to determine what the cause of this error is, however both users experience very laggy performance shortly after launching the application. I have not been able to duplicate the problem, and the developers have not been able to provide any response or possible causes yet.
I'd be very appreciative if anyone could help me make some sense of what this error type might mean. It's got something to do with the computer that the application is being run on. One user is on a Mac 10.3 using J2SE 1.4.2_12 and the other is on Win XP using Java 1.6_3Thank you Frank and Carole for your response. The stated issue/error is resolved. It had to do with the upgrade somehow which lead to multiple certs for the same agent. Anyway, I had to delete ADS and all attached Agents, re-create ADS, re-create all Agents and re-register with the new ADS. I then manually re-registered the Directory Server instances on both the Primary and Secondary Servers with the new ADS. Voila, the DSCC Web console no longer prompts for server credentials.
But importing the Wild card cert issue still remains. I added the issuing CA chain to the ldap instance CA store and I see the certs listed. But when I try to import the P12 cert/key combo, I get an error which says something like: "The certificate is already in the database". But it is not, verified using certutil.
Yes internal CA or Self-signed Certs are fine. If I add the internal CA and Root CA to the cert store on my LDAP clients, then I am fine. No SSL errors. But want to avoid using such as we do have quite a few clients which would be connecting to the store. Hence want to use our enterprise wild card Cert. I am not sure if it is an issue importing a wild card pkcs12 format.
As mentioned above I did add the CA chain (which issued the wild card) to the actual instance, not the ADS. I can try that. But are you sure we need to add the Root CA to Tomcat ks.
And while we are at it, the Self-signed certs generated using the Console is only valid for 2 years. Is it possible to change the term ?
Thanks again. -
Help me please need help on my java applet
hi there i have started a final year project on java.
it is a simple drawing applet however i need to be able to
save my drawings to a local hard disk. i have tried going through the tutorial but i dnt get it. please can any1 out there help me. my email address is [email protected] if you give me your email address i will mail you my program and maybe you could help me
AjIf you want an applet to write to user's local hard drive, there are many securiy issues that need to be resolved. How to resolve these issues depend on whether the applet uses a plugin (swing) or the browser's native JVM (no plugin, uses AWT only). In any event, the applet will probably need to be signed and the user's browser must be correctly configured. The following link gives you some detail on how to sign an applet that doesn't use swing:
http://home.attbi.com/~aokabc/FileIO/FileIOdemo.htm
The instructions on the first two links should point you to the right direction...

Need help with basic Java programming
I'm having a little bit of trouble with my code. For the sake of argument, I've removed the code I'm having trouble with, because I know it was inaccurate. I'm trying to create a loop so that this program will keep going through and through until the user enters an invalid variable. I thought the default after the case statements was supposed to make the system exit and output my message. Those two problems, the loop and the default, are what I'm really having problems with. My code is posted below.
import javax.swing.JOptionPane;
import java.util.Locale;
import java.text.NumberFormat;
public class Retail
public static void main(String args[])
String firstNum;
String secondNum;
String result;
int prodNum; //first number to input
double quantity; //second number to input
double total = 0.0; //total of Prod * Quantity Sold for all items
// To use American Dollar
NumberFormat moneyFormat = NumberFormat.getCurrencyInstance( Locale.US );
// first number entered as string
firstNum = JOptionPane.showInputDialog( "Enter product number 1-5" );
// second number entered as string
secondNum = JOptionPane.showInputDialog( " Enter quantity of items sold" );
// convert values to type double or int from type string
prodNum = Integer.parseInt( firstNum );
quantity = Double.parseDouble( secondNum);
result="";
if ( prodNum >=1 && prodNum <=5 ) {
switch (prodNum)
case 1: // 1st product
total = 2.98 * quantity;
break;
case 2: // 2nd product
total = 4.50 * quantity;
break;
case 3: // 3rd product
total = 9.98 * quantity;
break;
case 4: //4th product
total = 4.49 * quantity;
break;
case 5:
total = 6.87 * quantity;
break;
default: JOptionPane.showMessageDialog( null, "Wrong product number entered" );
JOptionPane.showMessageDialog( null, moneyFormat.format(total), "Total Price of Items Purchased", JOptionPane.INFORMATION_MESSAGE );
System.exit(0);
***I know I need to put something in the user input message to state that any value other than 1-5 entered will cause the program to skip to the output, I'll put that in later.***When you post code, please use [code] and [/code] tags as described in Formatting Help on the message entry page. It makes it much easier to read and prevents accidental markup from array indices like [i].
