I am looking to develop a program that does the following:
User selects Microsoft Excel xlsx, xlsm files.Program copies worksheets, userforms and modules from a template excel file into the user files.Program changes the XML schema of the files..I am looking for MAC compatibility too. Is Java suitable for this exact requirements I am asking?
I have an xml schema.. I need to display it as JSF datatable.This is my xml schema
XML FILE
<?xml version="1.0" encoding="UTF-8"?>
<shiporder orderid="889923" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="Shiporder.xsd">

A method in Java returns a schema. In .net, we use DataTable to get the data from the schema. How to write the following code in Java:
/* Result r = method();
r.DataSchema; */
using (DataTable tbl = new DataTable())
{
using (MemoryStream ms = new MemoryStream())
using (StreamWriter sr = new StreamWriter(ms))
[code]....
javax.xml.parsers.DocumentBuilder can build a document from a single stream which is the XML file. However, I can't find any way to also give it a schema file.
Is there a way to do this so that my XPath queries can perform type aware queries and return typed data?
We presently use dom4j/jaxen and it does this fine but I figure we should switch to the standard Java runtime if this has been added.
I need to create dynamic Layouts that are created from java source code, using JAXB. As FXML does not have a schema, this gets me in trouble.
Scene Builder cannot be used for dynamic Layouts, but if there really is no schema I could use, maybe someone knows how Scene Builder generates the fxml files.
We currently have an application which uses JDBC to connect to the backend database (DB version - 11.2.0.3 ). The application uses a properties file in which the password for the db schema is hardcoded in plain text format. Due to security restrictions we have been asked to make sure the password is encrypted in the file and no direct access is made to the schema using the plain text password. Best options we can use to make this password encrypted both at Oracle DB side and Java side.

I wanted to build an mp3 player as a Java project. One crucial part of the project involves being able to play an mp3 fie. I am not able to find the right api (if one exists) and am not able to find a suitable answer when searching on the web. A simple code snippet illustrating the playing of mp3 file using Java program. Also, I am using Eclipse IDE and how to import files if any importing of files is required.

I am downloading around 50 PDF files programmatically using Java program(like a servlet service) one after another in for loop. I am observing that , i'm getting timeout error after few files are downloaded itself. How to solve this problem and download more files programmatically using java? The files are in my server at different location.
View Replies View RelatedI am quite new to Java. I have downloaded a tictac example Java applet code and I run it on Eclipse with no problems. But when I try to test it outside Eclipse by doing the following:
I copy the .class file and two gif-images to another location and call the Java from html code:
<applet code="hello/HelloWorld.class" WIDTH="300" HEIGHT="300">
And I put the two gif-files to hello/images folder. I get and an error:
AccessControlException
access denied ("java.io.FilePermission")
"I:ImportantProgrammingWebProgramminghelloim ages
ot.gif" "read")
The path seems to be correct. I load the pictures from the Java code by:
notImage = getImage(getCodeBase(), "http://www.javaprogrammingforums.com/images/not.gif");
If I draw (drawLine) the X and O instead of using gif, then it works.... so its really the gif-loading which is the problem.

I have a program that is a XML-parser, and it works fine when I'm running it from NetBeans. But when I create a JAR-file and run the very same program, it cannot find the xml file. Consider this small program that addresses my problem:

import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;

I am trying to compile multiple jar files into one jar file from inside a java program. I know how to do this with shell scripts but I would rather have a universal application than one that will only run on Mac, Windows, or Linux. This is my current compiler code:
if(System.getProperty() == "Mac OS X"){
Runtime.getRuntime().exec("javac -classpath jar1.jar; jar2.jar");
}
I would then continue this on for Linux and Windows, but this limits my application.
I'm supposed to write a computer based testing program using files. I have started writing however, I am stuck. I am to prompt the user to enter the file name 'test.dat" and if something different is entered then a error message should be displayed. Also the file will create an input stream for the data using the file. I am to have the user enter other information about an employee and then write the record to the file.
The program should be created so when the user enters "quit" the loop is terminated and the file is closed. I'm not asking for code. I was just giving a brief synopsis of the project. Where I am stuck is I wrote the first part of the program that creates the file; however when I enter a wrong file name the exception error message does not display. The code is below:
import java.io.*;
import java.lang.*;
import java.util.*;
public class Project5Write

private Formatter x;
public void openFile(){

I'm creating ftp program which server will send not existing files on client to him.
There is method responsible for creating connection and sending list of files on client written by me.
Java Code:

System.out.print("Rozpoczęto działanie klienta");
strIP = jtfIP.getText();
intPort = Integer.parseInt(jtfNrPortu.getText());
clientPath= "C:/serweris/";
sck = new Socket(strIP, intPort);

Program is to find the most frequently used words across all the input files, where each word must appear at least once in each file.
View Replies View RelatedSo I am trying to write the output of two different java class files to one txt file while the program runs. The file name is determined before the program is ran, through the command prompt as arguments. How can I get the second class file to edit the same txt file without running into compile errors.
For right now I'm just going to send everything that the second file outputs to a message String variable, so that the Main class outputs to the the text file. I still want to learn how to write to the same text file directly from the second class file.
import java.io.*;
public class Test{
public static void main(String[] args) throws IOException{
int x;

File doc = new File(args[0]);

The program runs fine in netbeans project but once the jar is created it does not corporate with the text file. ("null" is returned) How can I attach text files to jar and exe?
I need to transformation the txt files into xml files, but each row txt files don't have same elements, for example the first book is composite one author
<books>
<book>Title</book>
<price>price</price>
<author>Author</author>
</books>
but the second book is composite two author
<books>
<book>Title</book>
<price>price</price>
<author>Author</author>
<author>Author2</author>
</books>
I would have the xml files with the number of authors variables, I can use JAXB for my problem?or not?

I'm reading from one file and writing it into another.I then want to delete the first file and use the second (it will get the first files name) .My sample java file works completely fine but it doesn't work on my actual file -it looks like it populates my test file like it should but it does not delete the original. Occasionally DMap.xml won't delete either - I try and rename it and normally I get the error of 'the file is open in Java platform SE binary' so the files is open somewhere - but I thought I had closed it correctly so have I done that wrong? I have put the basic code :
public class DeleteEnvironmentsWindow extends JDialog {
String xmlFile = "c:DMap.xml";
String fromFile =xmlFile
public void removeEnvironment(){
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
Document doc = null;
[code]....
know my code sample file of renaming a file and deleting an original file will work fine but when I use the code within my main java file - it appears to populate the file that I want populating fine but wont delete the origional. I have everything on my c drive so I can very easily keep track of what files I do and don't have.
Can using the same files in different methods cause problems? (Beginning Java forum at JavaRanch)
What is wrong with my code? System.out.println prints the correct name, but it fails when i try to rename the files in a directory.
