How Java Finds Jar Contents Imported In A Source File

Feb 10, 2015

how java imports libraries from a jar file inside a source. Let's say I have the following code on Something.java file,

import com.mycomanyA.*;
import com.mycomanyB.*;
public class Something{
public static void main(String ... args){
// code goes here...
}
}

And the Something.java is inside the following structure...

A.jar
com/
mycompanyA/
A.class
Another.class
B.jar
com/
mycompanyB/
B.class
neededImage.gif
bin-folder/
org/
apache/
Something.java

To compile this code(Something.java) from command line I want to use the following command,

javac org/apache/Something.class

And for the compilation to be successful, I'll have to be just above bin-folder because...

- > Only then my default class path will be (.) and java would automatically include A.jar and B.jar(the other way is to add the jar files using -cp argument, which I want to avoid in this scenario)

- > And for the import org.mycompanyX to work I'll have to be in the (.) directory.

Are my assumptions correct about how java find jar contents imported in a source file?

Jasper Report Is Only Showing Code (source View) Instead Of Design View

Mar 23, 2014

I am building a room management system in Java (Netbeans) and Ms Access. The jasper report is only showing code (source view) instead of design view.

File I/O - How To Process Contents From Input File

Mar 22, 2014

So my assignment is to read these values from an input file which I previously created. The 10 values represent miles traveled and I convert them using some formula my prof gave me to get the total cost, and output both values to an output file.

My programming question is the first number on the input file isnt a mileage value its the number 10, which is the number of values to be processed, which we're supposed to use in order to control a for or while loop which we'll use to process the contents of the input file. How would I create a while or for loop and get it to skip the first value of the input file?

We're not allowed to use arrays for this assignment.

Also here's my code so far, and it says its not being able to find the file, I made sure the file name is exactly as saved, and its saved in the same directory as the java class that i created for this assignment so I don't see what the problem could be?

Here's my the class with the main method

import java.util.*;
import java.io.*;
 public class QudratullahMommandi_3_07 {
 public static void main (String[]args)

[Code] ....

This is the error message I get

----jGRASP exec: javac -g QudratullahMommandi_3_07.java

QudratullahMommandi_3_07.java:17: error: unreported exception FileNotFoundException; must be caught or declared to be thrown
Scanner input = new Scanner(inputSource);
^
1 error

----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.

Validating The Contents Of A File?

Oct 21, 2014

I have the assignment of making an application that reads a file and then validates the contents to create a statistical report.

I have managed to have the application read the contents but im completely puzzled on how the validating works.

Is there coding in the file that put the numbers and words into the correct data types or is that also done in the application?

The application is to read the file of rugby scores and the produce the report with the amount of goals scored.

Swing/AWT/SWT :: Writing Out Contents Of JFrame To A File?

Aug 20, 2014

I obtained the following code online which purports to get the content of the JFrame:

public BufferedImage getScreenShot(
Component component) {
BufferedImage image = new BufferedImage(
winWidth,

[Code] .....

Then I write out the image with the following code:

BufferedImage screenShot = getScreenShot(c);
try{
File outputfile = new File(

When I double-click on the resulting file, all the images show up as black rectangles in Windows Photo Viewer. Yet the associated buffered image displays correctly in the window. I've tried 'jpg, 'png', and 'bmp' extensions, with matching formats in the write. I am using Win-7 64-bit. and jdk8 with matching jre.

Swing/AWT/SWT :: How To Generate PDF File Of The Contents In AWT Frame

Sep 25, 2014

I have been doing a project of ERP solution using JAVA AWT FRAMES and MYSQL(for database purpose). Here there is an ADMIN portion, who has the authority to make PAYROLLS of individual employees. There is a Frame where individual employee details will be shown(like basic salary, HRA, no.of leaves, other allowances...etc) in text boxes.

Now what i want is to make a PDF file of that payroll, so that I can make a hardcopy of it. The idea is just like anyother online form fill-up, where at the end you submit and save (or export) as a PDF (or text file) document. But I mention that it is a stanalone project, not an online one (i think it doesn't matter though).

So the basic idea is how to make a PDF file by extracting the text field or choice contents from a frame in JAVA AWT.

Read XML File And Delete Its Contents - Boolean Doesn't Appear To Work

Oct 17, 2014

I'm trying to read a xml file and delete it's contents. I do this by reading the file,writing it to a temp and then overwriting the original with the temp by renaming it

//overwrite original xml file with new file
boolean successful = outputFile.renameTo(inputFile);
System.out.println("success");

It does say the value of the local variable is not used however. I've debugged to ensure it hits the code it always prints out the line after too.It just does not overwrite my original xml file with the temp one.

It's had votes on stack so I thought that would of been reputableStack - overwrite but the second one got voted as a good answer. But still I would like to know if my code can work or not.

Display Contents Of File In Reverse Order - Output To Console

Jun 24, 2014

Create a class that allows the user to select a file and output the contents of the file to the console. Recommend using a text file to display, java files are text files. You may want to put this code in a method to allow you to complete the remainder of this assignment without overwriting your code.

- You should ask the user to enter the full path to your file to make certain you are processing the correct file.

- Modify your code/add a method to display the contents of the file in reverse order. You do not need to reverse the characters on each line but simply output the lines of the file in reverse order.

Hint: read the content of the file into an ArrayList and then traverse the ArrayList.

this is what i go so far.

package classActivity;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;
public class Select
{
public static String enterFilePath()

[Code] ....

Output Contents Of Input File In Alphabetical Order One Word Per Line

Jun 22, 2014

I am having a lot of trouble with this lab. basically I have to make a text processor to read in code put it into a file and output the contents of the input file in alphabetical order one word per line. I have to reference the string varaibles input_filename and output_filename.

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Scanner;
import java.io.File;
public class TextProcessor {

[Code] ....

these are the guidelines to said lab:

1. In the main method define two Strings called input_filename and output_filename. I will be setting these Strings to my own file names for testing your code, so make sure you get these variable names correct, and that you use them properly in the following steps.
2. Read in the text contents of the file referenced by input_filename.
3. Split the contents of the input text into separate tokens, using whitespace as a delimiter.
4. Lower case the tokens.
5. OPTIONAL: remove punctuation
6. Alphabetize the tokens.
7. Using output_filename, write the alphabetized tokens to an output file, one token per line.
8. Be sure to close file streams - no resource leaks!
9. Use methods to separate functionality in your program where possible

How To Print Contents Of Java Bean

I'm trying to debug a program and I need to see the values in a Bean. I tried

" system.out.println("OrderManager.java: packagePricing, packBean= "+packBean);"

but that just gives me

"OrderManager.java: packagePricing, packBean=com.voxportal.web.device.PackageBean@73dde7ae"

which I think is a reference to the bean but not the actual contents of the Bean.

How To Display Contents In Parallel Array Using Java

Feb 21, 2015

I have to write a program that calculates the average temperature for a month using parallel arrays (it is mandatory to use a parallel array). I'm new to Java (I'm more familiar with C++) so I get confused with the use of methods. I know how to compute the averages already, I just setting up the parallel arrays. This is what I have so far:

Java Code:

import javax.swing.*;
import java.util.Scanner;
public class Temperature {
public static void main(String[] args) {
String[] day = {"Monday", "Tuesday", "Wednesday",
"Thursday", "Friday", "Saturday", "Sunday"};
int[] temp = new int [7];

[Code] .....

For now I just want to show the contents in my array before I start computing averages.

JSF :: Updating View From AJAX

Sep 26, 2014

I have two images. I want to be able to click them and kick off a call to a listener in Java to change a value in the bean. I also want the view to update my dropdown (labeled "menuModel") to either be rendered or not, depending on which image I click. Alternatively, I would be fine with the dropdown simply being disabled and enabled for the same criteria.

So far, the listener kicks off fine, and the value gets updated correctly in the bean. However, the view never gets updated. I have tried this a hundred different ways, but nothing seems to work. If I hit refresh on my browser, the view updates. But I want it to do it automatically.

I am using standard JSF 2.1.

<div style="font-family: Verdana; font-size: 10pt; color: #FFFFFF">
<h2>Calibrations</h2>
<h:form id="tunerSelectionForm" style="color: #000000">
<h:commandLink>

JSF :: Possible To Map URL With Independent View Dir Structure?

Feb 16, 2015

Is it possible to map URL's with independent view dir structure? If so how?

My goal is to simply point an url to a specific view file:

i.e.

[URL] ....

to
not/default/path/views/main/index.xhtml
and
www.myserver.com/application/admin/
to
not/default/path/views/admin/index.xhtml

A couple solutions I found so far where:

Solution 1

PrettyFaces

I just didn't wanted to use a third party solution. This is my best solution so far.

Solution 2(a JSF solution):

navigation rule entries in the faces-config.xml file.

A bean is required, not a bad thing in above example but not great in combination with static navigation like:<h:commandButton action="index"/>

Solution 3 (another JSF solution)

Resource Library Contracts
This forces me to work in the contracts file.

None of the solutions gave me a clear solution except prettyfaces.

Are there some elegant native JSF solutions ? Something flexible and reusable? Something like a mvc controller i used to use in php applications. In this controller I was able to add a template file in the constructor and an content file in specific function. Custom paths where no problem. I didn't want to use mvc nor the php language in this project.
