Mar 22, 2015i have to save some particular info of a pdf file info into a database.there are lots of folders with tons of pdf files to be analized and then getting that info saved. make the process incremental? i need the program to stop at some point. and then continue to analize the resting files in the folders (i dont want the program to start all over again from 0 )my ideas are..sorting all the files using apache commons sort (by date) method (iv seen it somewhere) and saving the last file analized in the dabatase to then continue. OR just adding some extra character to the pdf file name that has been analized like for example xx-xxx.pdf to xx-xxxa.pdf.

Java Code To Grab All Files Located Under A Folder
Apr 25, 2014I am currently using the following Rally API Java code(below...in Java 1.7) to create an object and attach a file to it. This code works fine. But I need the code to be a little less specific and attach all files located under a folder (not just one file). How could one potentially rewrite this code (or use a different constructor/method) to accommodate such a thing? Also additional code how to narrow down results to all files with a creation date >= today.
Java Code:
import com.google.gson.JsonArray;
import com.google.gson.JsonElement;
import com.google.gson.JsonObject;
import com.rallydev.rest.RallyRestApi;
import com.rallydev.rest.request.CreateRequest;

How To Create Folder And Copy Documents From JAR File Into Folder With Code
Sep 8, 2014Where can I learn or how can I, being the most efficient way known to do so, create a folder outside my JAR file with the java source code, this then will copy YAML documents from my JAR file to that folder, then I need to read the YAML documents some way. I'm making an addon for a game, I am using an API that allows you to make a config.yml easily, and add and read entries from it, but I've read that I need to make my own methods to be able to create additional YAML documents.
I don't exactly know what to type in google to perhaps find such a page, but I did try to find a tutorial page about this or something and couldn't.
I've partially figured out how to create a folder, but I have a problem, how can I RETURN one directory to make the folder, I don't want to make the folder in the JAR file I want to make it just outside the Jar file in the same folder that the Jar file is at.

PrintWriter - Ask User For The Names Of Two Files
Jun 30, 2014Write a program that asks the user for the names of two files. The first file should be opened for reading and the second file should be opened for writing. Ihe program should read the contents of the first file, change all characters to uppercase, and store the results in the second file. The second file will be a copy of the first file, except that all the characters w ill be uppercase. Use Notepad or another text editor to create a simple file that can be used to test the program
Here is my code. I Also made two text document files that are located in the same directory as the .class file (the code file) that are named OriginalFile and UpperCase respectively. Please let me know what I need to do. Here is the code.

Copying Excel File Using Jxl API

import jxl.write.*;
public class MainProgram{
public static void main(String[]args){
try{
Workbook workbook = Workbook.getWorkbook(new File("myfile.xls"));
[Code]...
Not sure why this code isnt working for me, it makes an empty excel file called output, but never copies the contents in "myfile" to that output file. I have Excel 2010 but I saved both of them as 97-2003 workbooks. Am I missing something? Do you have to go cell by cell to copy an excel file with JXL?
Copying Objects Through Constructors?
Apr 4, 2014I have a class named Cash shown below
public class Cash
{
//Quanity Field and RetailItem Object field
private int total_units;
private Retail myRetail;
//Create first constructors
public Cash()
{
this(0,null);
[Code] ....
I'm seriously need to understand the concept of making shallow copies and deep copies. My book has shown me that its better to perform deep copies and I have followed that method. if you guys look in my constructor of the cash class
//Create a a constructor
public Cash(int total_units,Retail myRetail)
{
this.total_units=total_units;
this.myRetail=new Retail(myRetail);
Apparently I have field in Cash Class named
Retail myRetail
When I pass in an argument from my demo, I'm making a copy of that object from the demo class. In my retail class, I have the following copy constructor .
//Make a copy constructor
public Retail(Retail Object1)
{
Item_Name=Object1.Item_Name;
Item_Number=Object1.Item_Number;
// if I use this then my program would work//this.cost=Object1.cost;
//if I use this part of code below, my program won't work at all and I would get an error saying Exception in thread "main" java.lang.NullPointerException
this.cost.Item_Cost=Object1.cost.Item_Cost;
this.cost.Wholesale_Cost=Object1.cost.Wholesale_Cost;
}
My question is why can't I perform a deep copy there. I know if I do
this.myRetail=myRetail
in my cash constructor it would work, but then the book says its not a good method;
JSF :: Copying File From Server To Remote Machine
May 21, 2014I am developing a web application in java(JSF 2.0 - Prime Faces). I need to do below operation. My appllication is running on WLS server. WLS is deployed on a server(say Machine-X). In my application i have a requirement , where i have to copy file from Machine-X to another Machine-Y. The Machine-Y is access restricted.
When i tried to copy the file from my app, getting no access exception. I have full control over Machine-Y. We cannot use SFTP as SFTP cannot be installed on target machine(Machine-Y). Robocopy is failing for some use cases. Is there any other way we can copy/write file from one server to other by providing userid/password in java

Apr 7, 2014How do u copy all the elements in an array eg A into another array eg B? This is the question:

It is unknown at which point the numbers start to decrease. Write efficient code to code to copy the numbers in A to another array B so that B is sorted in ascending order. Your code must take advantage of the way the numbers are arranged in A.

Copying From One File (source) To Another File (destination)
Jul 5, 2014I have a file(source.txt) that contains some texts. Now, the java code is to run through each line in the source file and check if that line begins with a number and if true, copy that line to the destination file(destination.txt). I have the code but I am not sure why I can't loop through each line in the source.txt file. Below is my java code:
public static void copyFile(File source, File destination) {
BufferedReader br;
try {
FileWriter fw = new FileWriter(destination.getAbsoluteFile());
PrintWriter bw = new PrintWriter(fw);
br = new BufferedReader(new FileReader(source));
String line = new String();
[Code] ....
As shown in the source.txt file, there are 4 lines in the file but when the execution gets to while ((line = br.readLine()) != null) , it executes to false.. Why this is so?
below is the source.txt file
12 is a number
Green is bad
5 is not so cool
you are right
Copying Data Objects To Serializable Objects
Jul 27, 2014I am currently working on a project where I need to return data from a database over RMI to a client who requests it. Some of the fields in the Data Object can not be seen by the client so I need to create another object to send over the network instead. The method I use is this...
public static SerializableObject createSerializableObjectFromDataObject(DataObject dataObject){
SerializableObject serializableObject = new SerializableObject();
serializableObject.setField(dataObject.getField());
serializableObject.setAnotherField(dataObject.getAnotherField());
return serializableObject;
}
Is there a better way of doing this? I am creating many subclasses DataObject which all require this static method to be implemented and I can't push it into the superclass because each one needs custom behaviour.
