Help in translating JAVA code into CF

Hi all! I'm at the end of integrating an in-house calendar with Google calendars and all is working, however, I am stumped as to how implement callback functions. Here's what I'm trying to do as outlined on http://code.google.com/p/google-api-java-client/source/browse/Batch.wiki?repo=wiki
What I need to do is this section right here:
JsonBatchCallback<Calendar> callback = new JsonBatchCallback<Calendar>() {
public void onSuccess(Calendar calendar, HttpHeaders responseHeaders) {
    printCalendar(calendar);
    addedCalendarsUsingBatch.add(calendar);
public void onFailure(GoogleJsonError e, HttpHeaders responseHeaders) {
    System.out.println("Error Message: " + e.getMessage());
And then later pass it to:
client.calendars().insert(entry1).queue(batch, callback);
I believe I can pass one function by passing just the name of the function, but BatchCallback has two functions. Is this impossible to do in CF?
Thanks,
Ross.

1. In the future, please use a meaningful subject line, like "loop not performing last iteration." Just saying "Help in my java code" is useless. We know you need help with your Java code, else you wouldn't be posting here.

Run chm help file through java code

hello,
would you tell me how can i run a help.chm file using java code. i am trign this but no luck.
first try
Process pp=run.exec("C:/Program Files/Internet Explorer/IEXPLORE.exe ./res/bobftphelp.chm" );
Second try
Process pp=run.exec(" ./res/bobftphelp.chm" );
It run fine a help.doc file but not help.chm file.
please help me
Thanka in advance
Ravi Charan

The second address given to that function, does it relate to the class that its being called from? cause i've got
Runtime.getRuntime().exec("C:\\WINDOWS\\hh.exe .\\HelpFile_9_3.chm" );where HelpFile_9_3 is in the same folder as my class, but it won't work. Can anyone help?
Also, can you search within a chm file from Java? If I get that above code working, I presume it'll open the help file to the main page. I'd like to search within that document for a word or phrase - possible?
Thanks!

There are a lot of things to fix within your Program.
Why don't you try to fix your compiler errors by yourself before you ask others to do it for you ?
JOptionPane.showInputDialog returns a String and that can't be convertet to an int without parsing the String.
Some variables ar simply not declared and so on.
I've tried to fix the first switich case for you so you can see how it could possibly look like
int coal_qty, iron_qty, coal_price, iron_price, gold_qty, iron_input, coal_input, mythreal_input, mythreal_qty, adament_input, adament_qty, rune_input, rune_qty;
int selectId;
String select ;
double amount = 0.0;
double equation;
JOptionPane.showMessageDialog(null, "Created by:\n\tFinalFntsy3\n\nCopyright 2006", "Smelting Conversions", JOptionPane.PLAIN_MESSAGE);
select = JOptionPane.showInputDialog("Please type one of the following numbers: 1(Bronze), 2(Iron), 3(Steel), 4(Mythreal), 5(Adament), 6(Rune).");
selectId = Integer.parseInt(select);
switch(selectId)
   case 1:
       String gold_input;
       String tin_input;
       String copper_input;
       double tin_price = 1.0;
       double copper_price = 1.0;
     gold_input = JOptionPane.showInputDialog("Please enter the amount of gold available");
     tin_input = JOptionPane.showInputDialog("Please enter the price per piece of tin.");
     copper_input = JOptionPane.showInputDialog("Please enter the price per piece of copper.");
     tin_price = Double.parseDouble(tin_input);
     copper_price = Double.parseDouble(copper_input);
     gold_qty=Integer.parseInt(gold_input);
     equation = gold_qty/(tin_price + copper_price);

Help in using JAVA code in SAP XI

Hi,
I have some java and jar files, I want to use those files through SAP XI.
Scenario:
we need to do encryption of some data field which is coming as input to XI, Now here we have a readymade code for encryption in JAVA that we have to use. Now we have imported all the JAVA and jar files in the XI. and written a small code in XI editor which is calling some function of JAVA file. But we are getting error that system is not able to resolve the function name.
I think we need to define class path somewhere in XI.
Please help me to resolve this issue.
Thanks.

Hi Vin,
Here's all you should need to do:
1) Import the jar files into the IR as an Imported Archive.
2) You can then reference this from Message Maps (and XSLT maps). To do this in a Message Map:
a) Create a user-defined function.
b) Make sure to include the class in the import section. com.company.xi.MyClass for example.
The Imported Archive and the Message Map (or XSLT map) need to be in the same software component. If they're not, you'll need to setup dependencies in the SLD between the software components.
Thanks,
Jesse

Help needed on java code

Hi all,
In the below code, if condition is failing. what might be the reason.......??
String mAmtBaseStr = "-00000000000200.00";
          if (mAmtBaseStr.substring(0).equals("-"))
               //strip "-" from first char
               int len1 = mAmtBaseStr.length();
               mAmtBaseStr = mAmtBaseStr.substring((1 - 0),len1);
               //put the stripped "-" at last
               mAmtBaseStr = mAmtBaseStr + "-";
I tried other options like,
          if (mAmtBaseStr.substring(0,1).equals("-")) etc etc......

Hi,
        This code fails because of this reason
_problem1 _
String mAmtBaseStr = "-00000000000200.00";
mAmtBaseStr.substring(0)-------> -00000000000200.00 [as substring(0) returns entire string starting from index zero.]
when you are writing
if (mAmtBaseStr.substring(0).equals("-"))
     You are tryring to check if the value mAmtBaseStr.substring(0) [ "-00000000000200.00"] is equal to string "-" or not.
      As you can see the strings are not equal the if condition never returns you true value.
_Problem2_
you are nowhere checking whether the inbound string is null or empty. In case the string comes as null or empty java will throw an exception and your mapping will fail. So if input string does not begin with an hyphen you need to pass it as it is
Thus I would modify your code a little bit to make it work
public static String removeHyphen(String mAmtBaseStr)
          if (mAmtBaseStr!=null && mAmtBaseStr!="" && mAmtBaseStr.substring(0,1).equals("-"))
               //strip "-" from first char
               int len1 = mAmtBaseStr.length();
               mAmtBaseStr = mAmtBaseStr.substring((1 - 0),len1);
               //put the stripped "-" at last
               mAmtBaseStr = mAmtBaseStr + "-";
          return mAmtBaseStr;
This code works and produces required output
input: -00000000000200.00
output: 00000000000200.00-

Needed help with updating java code

Hello all,
Let me begin by let you know I am not a programmer and I have tried to solve this by reading on the net. I am a network admin so I tech knowledge but no programming.
I have a webcam sending a Jpg to an FTP site and there I have used an applet called view.class to refresh once a second.
site:http://70.154.170.253/webcamold.html
My problems is now that it refreshes the same image over and over. It refreshes the cached image not the new image.
From reading I suspect that it has to do with the newer version of java (it used to work fine).
I have tried using JavaCam but same issue it just refreshes cached image. Also image flickers, the applet I am trying to fix was really smooth.
I have also tried to compile code that I found on this forum but I got error dealing with deprecated code.
Any help would be greatly appreciated!!!
Code:
import java.applet.Applet;

public class View extends Applet

String s = getParameter("refresh");
if(s == null)
update = 30;
else
try
update = Integer.parseInt(s);
catch(Exception _ex)
update = 30;
filename = getParameter("picture");
if(filename == null)
System.out.println("No filename given as parameter.");
md = new MediaTracker(this);
off = createImage(size().width, size().height);
refreshImage();
public void paint(Graphics g)
g.drawImage(off, 0, 0, this);

paint(g);
public void refreshImage()
img = getImage(getDocumentBase(), filename);
md.addImage(img, 0);

catch(Exception exception)

Require help in my ABAP code

Hi All,
My design wont allow Delta loads because the transformation source is an InfoSet. To limit the data in these loads, I require a filter in the DTPs on fiscal year/period then only load I can load the current month and 2 prior months. Now we are updating manually for the DTPs.   To eliminate this monthly task a dynamic filter (routine) needs should be used rather than a static filter.
So I have written as follows But in the debugger mode am able to see the -3months to the current date but records are not filtered. Any help please

1. In the future, please use a meaningful subject line, like "loop not performing last iteration." Just saying "Help in my java code" is useless. We know you need help with your Java code, else you wouldn't be posting here.
2. Repost your code without those annoying superfluous asterisks, and with proper indentation in the section that they are currently polluting. It's too hard to read as-is.

How doest jdk docs help as in writing java code?

hi i wonder how does jdk docs help as in writing java code because if i google a java code the jdk docs always becomes the result of my search but in my experience jdk docs never helps me.
is there any one know how to use jdk docs? and how to get the code from there.
im telling about jdk docs from here http://download.oracle.com/javase/1.4.2/docs/api/
cross posted from http://www.thenewboston.com/forum/viewtopic.php?f=119&t=13778

Your question still does not make any sense, and you still haven't clarified what you're not understanding.
However, if you think that just by reading the API docs, with no other training or study, that you will be able to write that code, then you are seriously misunderstanding the purpose of the docs.
Obviously English is not your native language. You grew up speaking some other language at home and with your friends, and at some point in school or as private study, you started to learn English. You learned about the grammar and the alphabet and pronunciation, sentence structure, word order, etc. Now you have the basics of how the language works, and you know some words. When you want to learn new words to fit into the structure you have learned, you use a dictionary.
If you didn't study the grammar, sentence structure, etc., and just said, "I want to learn English. I will look at a dicationary," clearly that would not work.
Right?
So, since you now understand and agree with the English example, let me state something that I hope is obvious to you by now: The API docs are your dictionary. They are not a substitute for learning the language basics.
Furthermore, once you know the language basics in English and have your dictionary, you still won't know how to write a resume (which you may know as a CV). You will look at examples and perhaps take a course on resume (CV) writing. Just reading a dictionary won't help you write a resume(CV). Similarly, if you know some Java basics, you can't learn how to write a Swing app just by reading the Javadocs. You'll look at tutorials and examples. Then, once you know the basic structure of a Swing app, you'll look to the javadocs for more details about more kinds of GUI classes--different buttons and windows and panes and panels and layout managers, etc.

What is this Java-code doing?

I tried to find out what this part of a JAVA code is doing.
I think that there are the two Strings 'target' and 'phrase'
declared and initialized, however, what is the value of each
of these two Strings then respectively what is the return value??
Here youe see the code:
1:....
2: private String O00OoO0O0oOoo00O00oo(String target, String phrase)
3: {
4: for(; target.length() > phrase.length(); phrase += phrase);
5: String s1 = "";
6: for(int i = 0; i < target.length(); i++)
7: s1 = s1 + "" + (char)((phrase.charAt(i) + target.charAt 8: (i)) - i);
9:
10: return s1;
11: }
thx for help!

I wrote the following program :
public static void{
1: private String abcdefghabcdefgh(String target, String phrase)
2: {
3: for(; target.length() > phrase.length(); phrase += phrase);
4: String a = "";
5: for(int i = 0; i < target.length(); i++)
6: a = a + "" + (char)(target.charAt(i) - phrase.charAt(i) - i);
7: System.out.println(a);
8: return a;
9: }
10: String pass="xxxx";
11: String ssap="oooo";
12: String test = "";
13: test = abcdefghabcdefgh(pass, ssap);
14: System.out.println(test);
15:}
But I always got an error when I tried to compile it...
and i tried to find out for hours a de5cription for this function...
Actually I found the de5cription for String(String original) in the
API documentation, and I think this is what I wrote in line 1...
I tried so much versions so that this function would work...
but it didn't at all. (Actually I think that I importet all the java classes
I need). What the hell are I'm doing Wrong???!!!

Welcome to the forum. I think that George123 has your problem and its solution well in hand. Follow his good advice and you will have solved this problem. One other thing though just for future reference. If you post your code, here, you are going to want someone to be able to read it easily. Please use code tags when posting next time and your code will be much easier on the eye. You can find out about them here:

Can anybody help on sending mail through Java Code

I am trying to send the mail using the java code and I am unable to do it. My code is
import java.io.*;
import java.net.*;
import java.util.*;
import java.text.*;
public class EmailExample {
public static void main(String[] args)
Socket smtpSocket;
DataOutputStream os;
BufferedReader is;
Date dDate = new Date();
DateFormat dFormat = DateFormat.getDateInstance(DateFormat.FULL,Locale.US);
try
smtpSocket = new Socket("www.gmail.com",80);
os = new DataOutputStream(smtpSocket.getOutputStream());
is = new BufferedReader(new InputStreamReader(smtpSocket.getInputStream()));
System.out.println("Hi How is this?");
os.writeBytes("HELLO\r\n");
// You will add the email address that the server
// you are using know you as.
os.writeBytes("MAIL From: <[email protected]>\r\n");
// Who the email is going to.
os.writeBytes("RCPT To: <[email protected]>\r\n");
//IF you want to send a CC then you will have to add this
//os.writeBytes("RCPT Cc: <[email protected]>\r\n");
// Now we are ready to add the message and the
// header of the email to be sent out.
os.writeBytes("DATA\r\n");
os.writeBytes("X-Mailer: Via Java\r\n");
os.writeBytes("DATE: " + dFormat.format(dDate) + "\r\n");
System.out.println("DATE: " + dFormat.format(dDate) + "\r\n");
os.writeBytes("From: Me <[email protected]>\r\n");
os.writeBytes("To: YOU <[email protected]>\r\n");
//Again if you want to send a CC then add this.
//os.writeBytes("Cc: CCDUDE <[email protected]>\r\n");
//Here you can now add a BCC to the message as well
//os.writeBytes("RCPT Bcc: BCCDude<[email protected]>\r\n");
String sMessage = "Your subjectline here";
os.writeBytes("Subject: Your subjectline here\r\n");
os.writeBytes(sMessage + "\r\n");
os.writeBytes("\r\n.\r\n");
os.writeBytes("QUIT\r\n");
// Now send the email off and check the server reply.
// Was an OK is reached you are complete.
String responseline;
while((responseline = is.readLine())!=null)
{ System.out.println(responseline);
if(responseline.indexOf("Ok") != -1)
break;
} catch (IOException e) {
e.printStackTrace();
It is compiling and runnung properly. Please Help me on this.
Thanks.
Satya.

You're mishandling the responses. You terminate if you don't get an "Ok" string, but that's not how success is defined - you should get a 200 code back, typically with an "OK" (not caps) message.
It doesn't help that you're ignoring all of the server output after each command, so you never find out if anything goes wrong.
You're also reinventing a wheel. The JavaMail API exists for this: http://java.sun.com/products/javamail/

Java code to create a new .txt file in FTP server --- Help

Hi,
I wrote a standalone java app which creates a .txt file in my local machine and transfers it to FTP server. But my requirement now is to create a new .txt file with the same content in FTP server itself instead of creating locally with basic java code.
I'm aware of transfering file from local machine to the FTP server using STOR command of FTP. But i never tried creating a new file & writing content into that in FTP server.
So, if any one did this before please help me out with source code or any idea ???
Thank you.
Vj.

thanks for your reply. yes i've seen the Apache Commons NET API , but there is no method or class to create a new file in FTP server. I'm really worried how to solve this problem ???Sure there is.
There's a method where you can write data to a file on the server using an OutputStream, right? Well, instead of writing to a FileOutputStream, write to that OutputStream instead. Remember to close the OutputStream and call the method which says you're finished with the command (I forget what it's called).
