Java program Compiling using Maven

Hi,
I am upgrading 1.4 to 1.5 java. And in my local pc i have compiled programs and able to eploy the application. But the problem is in server when i try to compile using maven it gives a compilation error.
If you are saying that it is an issue of maven then also i wanted to discuss this strange issue here.
/usr/build/Application/java/com/sql/DataStoreInterface.java:686: warning: unmappable character for encoding UTF8
    [javac] ï¿½* Inserts a blank row at the specified position of the DataStore's result set buffer. Returns the number of the row added.The statement is commented but the compiler is not identified the same. When i checked encoding type using file --mime {filename} i got it like text/x-java; charset=iso-8859-1. This is not the case for all some java file types are text/x-c++; charset=us-ascii but that is not giving error.
One more issue is elicited below.
] cast to java.lang.Object for a varargs call
    [javac] cast to java.lang.Object[] for a non-varargs call and to suppress this warning
    [javac]                     meth.invoke(comp, n);
    [javac]                                       ^Can any one suggest how can i solve this two issues.
Thanks
Rasa.

[javac] ï¿½ ...ï¿½ above might be a broken copyright #) symbol. In java code comments, I'd replace it with word *(copyright)*
#) broken copyright symbol -- I've seen it broken that way in one project. I remembered this because one of colleagues made a funny remark on it. There was something like:
...it's not a bug, these are sacral signs with a very special meaning.
Let me explain:
- i with two dots means we spotted all i's and some more
- reverted question sign means there are no questions left anymore
- "1/2" is a math symbol for square root meaning we've got to the roots of the Universe with our product

Java programming language uses call by reference for objects?

Is Java programming language uses call by reference for objects?

Yes. You make calls to an object via itsreference.
No.Yes, you're referring to passing a reference into a
method in which case the value of the
reference is passed.I believe the OP is using the term "call by reference" to mean "pass by reference." The two are interchangable, AFAIK. So, while "making calls to an object via its reference" is correct, I don't believe it's germane to the question.

Writing java program that uses UMTS service

Hi
I wonder if it is possible to write java programs that use UMTS services. Is there any class-package in java related with UMTS services?

you can call a batch file using NT service. the batch file executes the java program. and you can also send an email thru that java program.

Is it possible to run a java program without using the command prompt?

Hi,
I was wondering whether it is possible to run a Java program (not an applet) without using a command line in the command prompt?
Basically I want to run a program that will be continually running in the background and hence I don't want to have a command prompt screen loaded up as well - I just want the program to be running in the task bar.
I know how to run the program in the task bar - but I still need to launch the program from the command prompt - is there anyway I can get a program running without having to start it from the command prompt?
Cheers

Or create a desktop shortcut (in Windows) or an application launcher ( in Linux GUI).

Steps to read PDF using Java Program that uses LifecycleES Jboss server

Can anyone please mention the steps to setup the Jboss server in Lifecycle ES suite....
i have program to read PDF that has following contents --and it Fails to connect to LiveCycle server via RMI. Please help me out.....
Properties connectionProps = new Properties();

Vinay,
i dont think that any body can read and write pdf files by java program.b'coz pdf files will have its own proprietery encoding format.
Here is something u gotto remember when u post an answer to somebody's question. Never ever answer until u r very sure about something or u r a nerd in that area. Don't give a trivial or a insensible answer.
Hope u learn the forum etiquette.

How can I make a Java program pyramid using for loops??

Hi guys, so I'm stuck with my program here... I don't know how to make it work, and i've been trying really hard.. So now i give up and need some guidance.. Please help me here.
Your job in this assignment is to write programs to solve each of these six problems.
1. Write a GraphicsProgram subclass that draws a pyramid consisting of bricks
arranged in horizontal rows, so that the number of bricks in each row decreases by
one as you move up the pyramid, as shown in the following sample run:
The pyramid should be centered at the bottom of the window and should use
constants for the following parameters:
BRICK_WIDTH The width of each brick (30 pixels)
BRICK_HEIGHT The height of each brick (12 pixels)
BRICKS_IN_BASE The number of bricks in the base (14)
The numbers in parentheses show the values for this diagram, but you must be able
to change those values in your program.
* File: Pyramid.java
* Name:
* Section Leader:
* This file is the starter file for the Pyramid problem.
* It includes definitions of the constants that match the
* sample run in the assignment, but you should make sure
* that changing these values causes the generated display
* to change accordingly.
import acm.graphics.*;
import acm.program.*;
import java.awt.*;
public class Pyramid extends GraphicsProgram {
/** Width of each brick in pixels */
     private static final int BRICK_WIDTH = 30;
/** Width of each brick in pixels */
     private static final int BRICK_HEIGHT = 12;
/** Number of bricks in the base of the pyramid */
     private static final int BRICKS_IN_BASE = 14;
     public void run() {
}That's my problem.

yo, so i figure out my for loop. my code is very very very very ugly, so dont laugh i know its ugly! just wanna ask for some tips
public void run() {
          int initBrick = 30;
          int initPlacement = (getWidth() - BRICK_WIDTH) / 2;
          for (int i = 0; i < initBrick; i += 30)
               int initX = i;
               int x = initX + initPlacement;
               GRect brick = new GRect(x, 0, BRICK_WIDTH, BRICK_HEIGHT);
               add(brick);
          for (int i = 0; i < 60; i += 30)
               int initX = i;

     }So yeah, it's very ugly. not general. BUT now; I know the logic of the program..
I need to change 3 variables here.
the Y var, the X variable, and the size of the loop test..
so I need to make a one compact for loop that will change those 3 for every time the loop finish, or for every row the variable will change...
Ill try to think again, ill head to the balcony, and squeeze my brain. YEAH it took me this long to figure this out, anyway im a noob YET. But i was working a while ago.
ANYWAY, leave some tips please.. I NEED TIPS NOT SOLUTION

Java program compiles but failes to run

WHAT IS WRONG WITH THIS PROGRAM? It compiles;
however, when I try to run it, I get the message"
static void main not define in class car. Please help!
class Car {
int passanger;
int mpg;
int gas;
void range() {
System.out.println("Distance of =:" + mpg*gas);
class Models {
public static void main(String args[]) {
Car Toyata=new Car();
Car Mazada=new Car();
Toyata.passanger=8;
Mazada.passanger=6;
Toyata.mpg=30;
Mazada.mpg=25;
Toyata.gas=16;
Mazada.gas=17;
System.out.println("Toyata can carry" +Toyata.passanger);
Toyata.range();

The program gets compiled into two classes: Car.class & Models.class.
class Car {
int passanger;
int mpg;
int gas;
void range() {
System.out.println("Distance of =:" + mpg*gas);
class Models {
public static void main(String args[]) {
Car Toyata=new Car();
Car Mazada=new Car();
Toyata.passanger=8;
Mazada.passanger=6;
Toyata.mpg=30;
Mazada.mpg=25;
Toyata.gas=16;
Mazada.gas=17;
System.out.println("Toyata can carry" +Toyata.passanger);
Toyata.range();
java Car does not produce output because the main method is in the Models.class.
java Modelsproduces output
Toyaota can carry 8
Distance of :=480

Trying to get my first java program compile.

I just iinstalled j2sdk1.4.2_05 on Wind 98 and I have set the path variable in autoexec.bat and ran the .bat.
So, now the system recognizes the javac compiler but I am still not able to run a program Welcome.java
I created a Welcome.java file and stored it in C:\java\Welcome.java
I also set the sourcepath to sourcepath=c:\java; in my autoexec.bat file.
When I compile the following way, I get the following error:
c:\javac Welcome.java
Error: Cannot read: Welcome.java
Can anybody please tell me what I am doing wrong. Do i need to set any thing else.
Radhika.

I got it to compile and run....successfully.
Problem was- When I created the file Welcome.java in Notepad, it created with the following extension-
Welcome.java.txt. I renamed it to Welcome.java and it compiled and ran fine.
Thanks,
Radhika.

You find examples and code by searching the internet, not by using forums.
Start with The Java Tutorials - it has trails for the bulk of the Java functionality.
See the trail 'How to Write an Undoable Edit Listener'
http://docs.oracle.com/javase/tutorial/uiswing/events/undoableeditlistener.html
You learn by DOING - not by reading. Actually DO the tutorial example and try to understand WHAT it does and HOW it does it.
Then search for other tutorial trails that are of interest.

Need to change the directory using the java program

hi,
can anyone give me the code to change the directory in the java program by using the system command.
as in C where we use the system call system("cd");
the same way how to do that in java. please help me with that!!!

Please search the forums for "runtime.exec", there are dozens of examples posted.
Although this may not do you any good, since changing the os's directory is not likely to change anything you're using in Java. What are you trying to do?

Java programming

I am new to Java programming and using the compiler "javac" from the command prompt. When I get morethan 6 or 7 errors the screen scrolls so fast I cannot read the first error message. Is there a way I can use to pause the screen or redirect the error messages to a text file?
My second question is how do you convert a double value to an integer value. I tried "intValue" but it's not working. Please reply as soon as possible.

If its WIN 2000 or NT first execute your programs from batch files. last line of batch file should be "pause". while the window is still open, right click on the top left corner and increase the buffer size.
If that doesent work you can try
javac classfile > outputfile
That might work on windows systems
