Importing Apache Commons?

Feb 18, 2014

I've got this annoying error message when trying to import:

import org.apache.commons.codec.binary.Hex.encodeHex;

"Import org.apache.commons.codec cannot be resolved", which after searching seems to be a somewhat common problem. The solution being to go to: FileUpload - Home and download some jar file and add it to the /web-inf/lib folder. yet the error persists even after adding the jar file in "add external jar files" and restarting eclipse.

The jar file I added is called "commons-fileupload-1.3.1.jar" which is the only one I could find in the zip file. I've searched around looking at numerous threads about the issue, several of them sadly several years old, with no success.Surely installing a library to eclipse shouldn't be this complicated?

Importing External Libraries Such As Apache Commons?

Dec 10, 2014

I'm currently using TextPad or command prompt to compile and run my programs, and as usual I am not having any luck importing external libraries, in particular apache commons.

I couldn't see any particularly obvious settings in TextPad to set a library or class path (which is annoying as I really like the program), so I jumped back to cmd prompt to run it from there. Aaaaaand i don't understand .

This is my file structure at present:

/mainProject //includes .java and .class files, and where I've successfully placed .jar files before.

The apache commons zip file was extracted here, making:

/mainProject/commons-lang3/apidocs/orgs/apache/commons/<folders> //the commons-lang3 folder contains the jars I'm navigating to the /mainProject folder in cmd prompt and typing (amongst many other things) javac -cp /mainProject/commons-lang3 MonsterGame.java //with the -cp being pointed at the folder the .jar is in i've tried pointing it at the root folder where the import statement begins in the code (ie mainProject/commons-lang3/apidocs), tried moving the .jar files to the mainProject folder (pointing -cp at it) and more. No luck.

it seems everytime i try to import a new library something goes wrong..... its become a bit of a stumbling block to be honest. I seem to spend most of my time dealing with the 'administrative' side of coding (that was the politest way i could put it ), am I not doing it right?

I've read I'm supposed to include the .jar in the classpath, not just the directory. is this correct? (it still doesn't work...!)

Does Importing Whole Package Use More Memory Than Only Importing Specific Package Parts?

May 22, 2014

Let's say hypothetically you're making a huge program and use a lot of imports (ex import java.util). If you only need a few specific things from java.util, will it use more memory importing java.util.* compared to only importing lets say java.util.Scanner, java.util.ArrayList, etc. Basically does importing a whole package use more (if any at all) memory than only importing specific package parts?

Servlets :: Dojo Progressbar Not Working Properly With Commons FileUpload

Sep 22, 2014

I have been trying different examples on showing progress bar for file upload progress for couple of days.

Some of the different example were using libraries like Dojo,jQuery and just using plain AJAX with iframe method.

But unfortunately, however i try i'm not able to show the progressbar thingy at all although the upload part is working good.

Following is the example with Dojo[dojo-release-1.0.3]

I'm using Servlet 2.5,commons fileupload libs, TomEE-plus-1.7. 0 & ant for building tool in ubuntu 12.04 as the platform with firefox 32.

Here is the code (as it was in the site)

build.xml
<?xml version="1.0" encoding="UTF-8"?>
<project name="upldEx6" basedir="." default="clean">
<!-- Properties start-->

[Code]....

If i choose a file of size 68MB, on page load the progressbar is seen but stays at 0% all the time even after submttting the form.

On debugging, cant find error/bug here.

P.S This code can be seen CodeGuru: FileUpload Example

Cannot Find File Apache POI

Sep 2, 2014

I'm trying to read a .xlsx file using Apache Poi on Eclipse and store the data into an ArrayList.

My code :

import org.apache.poi.ss.usermodel.*;
import java.io.*;
import java.util.*; 
public class parseReadFiles
{
public static void main(String[] args) {

[Code] ....

I keep getting a FileNotFoundException: Users/Divjot/Desktop/first.xlsx (No such file or directory). I've tried different combinations of file names and paths but can't get the program to find it. Should the file be stored in a special place or should the class path be different?

Apache POI Method Returning Wrong Value

May 20, 2014

I'm using apache POI to input data from a excel database. I have a method that is supposed to count the number of rows containing data so I can use that number to initialize an object array. It's returning one more than the actual number of rows and I can't figure out why.

public int getDataRange() throws IOException{
int rowCount = 0;
Iterator<Row> rows = sheet.rowIterator();
while(rows.hasNext()){
HSSFRow row = (HSSFRow) rows.next();
rowCount++;

[Code] .....

I get an array index out of bounds exception at the highlighted line.

Java Program Using Apache POI Giving Exceptions

May 13, 2015

I am having some serious difficulty getting my project off the ground. I have the following code:

FileInputStream file = new FileInputStream(new File("src/retestchecker/test_sheet.xlsx"));
//Get the workbook instance for XLS file
XSSFWorkbook workbook = new XSSFWorkbook(file);
//Get first sheet from the workbook
XSSFSheet sheet = workbook.getSheetAt(0);
Row row = sheet.getRow(0);
Cell x = row.getCell(3);
System.out.println(x);

Everything is properly imported, etc etc.. But I am getting this error and I am not sure what it means:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/xmlbeans/XmlException
at retestchecker.RetestChecker.main(RetestChecker.java:23)
Caused by: java.lang.ClassNotFoundException: org.apache.xmlbeans.XmlException
at java.net.URLClassLoader$1.run(URLClassLoader.java:372)

[Code] .....

Java Result: 1

I am using Netbeans and the latest version of Apache POI that was released May 11, 2015.

The line 23 that the error refers to is this line:

XSSFWorkbook workbook = new XSSFWorkbook(file);

Apache Poi To Create Excel File From JTable

Sep 17, 2014

I'm using Apache Poi to create an Excel file from a JTable.

I want to open the file directly in Excel, rather than first write it to disk and then open it from the disk.

FileOutputStream output = new FileOutputStream( StolleExcel.xls" );
workBook.write( output );
Desktop dt = Desktop.getDesktop();
dt.open( new File( "StolleExcel.xls" ) );

output.close();

Is there a temporary way of saving the Excel object then just opening it with Excel, so the user can save or edit whatever they want?

Importing CSV / Reading Data And Have A Count Using Queries

Oct 11, 2014

Ok so I know how to import a csv using java. What I'm curious about doing is importing a csv using file chooser, reading the data, sorting the data out by certain parameters, and then outputting a count of each parameter I chose. Say for example I have columns 1,2 and 3. Column 1 has the name, column 2 has the percentage, column 3 has an o'clock time. I want to use queries to sort through the parameters and have a count of each parameter I choose...

Importing And Creating Objects From The Text Files?

May 25, 2014

I've been trying to write a program for some time now, but im encountering problems while trying to complete it. The program has a student class and a course class (set up with some info about the class, like #, professor name, course title, course time). Now, i have a text file in the workspace, and i have to import the data from the textfile, and thats just what i did, but then there is an option which allows the user to delete a course only by inputing the course number, and when he does that, the program outputs the course's name, and confirms the deletion of the course (From the student's record, i created a vector for that and imported all the courses from the text file). But how can i let the program know what's the name of the course when the user inputs the course number ???

When the data is read from the file, objects should be created and added to the student's course record. <- i think here's where i messed up ? i imported the data, but how can i actually make them objects before adding them into the vector ?

PHP Code:

public static void main(String[] args) throws IOException
{
Scanner scan = new Scanner(System.in);
Vector Record = new Vector();
try {FileReader filereader = new FileReader("CLASSES.txt");
BufferedReader bufferedreader = new BufferedReader(filereader);
String test = "";
while(test != null)
{
Record.addElement(test);
test = bufferedreader.readLine();
} mh_sh_highlight_all('php');

Swing/AWT/SWT :: Extending Classes And Importing Libraries Basics?

Mar 12, 2015

1. Tried to use setLayout() but it wouldn't let me. Have imported libs

import javax.swing.*;
import java.awt.*;

but it doesn't work. It only worked when I extended a class with JFrame. Why do I have to do it? I already have a JFrame instance:

public test(){
JFrame frame = new JFrame();
frame.setTitle("Workshop");
frame.setBounds(500,300,400,300);
frame.setVisible(true);
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
....
}

This code runs smooth, so it's confusing for me that it lets me create a JFrame object, and put buttons onto it, but it wants me to extend the class onto JFrame class in order to use a method.

2. I've read somewhere that AWT is old and should not be used anymore. Is there a diagram or a list with objects and properties that are manipulated only by Swing so that I could concentrate only on those? For example (made up list):

JPaper -

- width, setWidth(x)
- height, setHeight(x)
- position, setPosition(x,y)
- color, setBackground(RGBa)
- acquire, add(subordinate component)
- deprive, remove( subordinate comopnent)
- etc...

JSticker -

- width ...
- height ...
- write, setText(String)
- etc...

JavaWs - Importing Two JNLP Files Into System Cache

May 8, 2014

Have an issue with deploying our application, which comes in two parts, with javaws . In our installer (which is coded in NSIS) we call javaws twice, each time referencing a different jnlp file. It looks like this:

javaws -wait -shortcut -import -system http://192.168.1.82/launch?[params]

javaws -wait -shortcut -import -system http://192.168.1.82/launch?[slightly different params]

Whichever jnlp file is second gets imported into System Applications. My guess is that it is overwriting the first imported application.
