I try to create a new xml file with DOM parser and i get this error in line 73.

I've recently tried to write a file parser for the .x3d file type as it's one of the few 3d model types I can find written in easy to understand (and interpret) English. While it technically does work (or what I have so far), the issue is that it takes far too long (17 minutes) to parse just a part of the file (the vertices of the model).This is the code for the object itself:
import java.io.*;
import com.sun.j3d.utils.geometry.*;
import javax.media.j3d.*;
import javax.vecmath.*;
public class ModelLoader {
BranchGroup object = new BranchGroup();
BufferedReader reader;
String line = "start";
[code]....
Anyway, here are some observations I've made about the file:
-The line in the file itself that contains all the vertices is all one giant string according to the file.
-There are apparently 18,000 vertices in all (according to the command at line 18).
-Unless Netbeans automatically terminates infinite loops after a certain amount of time, it is most definitely NOT an infinite loop as I have seen the program terminate on its own (after 17 minutes, though).
I had a theory that maybe organizing each vertex into its own line and then having the program switch to the next line when it's done reading that vertex might make the program run faster, but I'm not sure why it would, so I thought I'd come here in case that theory turned out to be a dead end.
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.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import javax.xml.parsers.DocumentBuilder;

There is JAVA Sql parser which supports all ASCII characters in my project. This parser fails when the query contains multi byte characters.We have used UTF8 encoding. How to handle multi byte chars.
View Replies View Relatedi am having a below piece of code in my worker thread. In my output i am getting xml records from the database. I'm sending this output to a input stream & finally to a sax parser.My query is, before sending to the parser i need to store the input stream in buffer. The buffer should store 1000 records. For every 1000 records the parser should be called from buffer.
while (orset.next()) {
output = orset.getString("xmlrecord");
writeCount++;
InputStream in = new ByteArrayInputStream(output.getBytes("UTF-8"));
InputStream inputStream = new ByteArrayInputStream(output.getBytes("UTF-8"));
Reader reader = new InputStreamReader(inputStream,"UTF-8");

how to use SAX Parsers. I've looked at a few tutorials and have the generals down. I have an xml file that the parser is trying to read. As you see below, at the start of each element, I add the tag to an arrayList of the tags. I create a stringBuilder to capture the text between tags, this won't work unless it occurs at the end of an element. If it occurs at the start, it never gets the chance to read the text.
This is where the problem occurs. For nested tags, like project, it reads the last nested tags' text and stores it in the text arrayList. Project may be the first indexed tag in the tags arrayList, but project's text is the fourth indexed element of the text arrayList. So when my test print the arrayLists by index, it gets thrown off. I want over tags to store a blank space in the text array, and at the same index of the tag its associated with. How would I do this?
I've tried overwriting the text arrayList, but couldn't get my logic thought out for how to determine if a tag was nested. I always ended up overwriting blank space to each element.

I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...
The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data. Here is the base Product class that must be used to create the objects for the array.
public class Product
{
public String pName;
public String stringName;
public double price;
public int quanity;
[Code]...
these continue for about 40-50 entries, they are not seperated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name seperated with spaces, then price after a comma, then quanity after the second comma.....

I am new to java and I am creating a system that will ask the user to create a file that will store to a text file, Once the user created the file I have a class that will let the user input the subject name that has been created, However, I keep on getting this java.util.nosuchelementexception.Here's my code:
public void display_by_name()
{
String id, name,total;
String key[]=new String[30];
String value[]=new String[30];
int i=0;

Well my code is supposed to ask for an input file and then (ex: input.txt), read the input file and create an output.txt file with the anagram for the words in the file. Also it should be displayed on the screen. However my code doesn't display the anagram on screen or the output file!
Heres is the code:
import java.io.*;
import java.lang.*;
import java.util.*;
/* This program will read a file given by the user, read the words within the file and determine anagrams of the given words. If the file that the user inputs is empty, then the program will output "The input file is empty."
* The program will read the file line by line, counting the total number of words read. If there are more than 50 words, "There are more than 50 words."
* will be printed, and the program will terminate. After each line is read, the words in the line will be separated,punctuation characters will be removed, and upper case characters will be switched to lower case.
* If any word is larger than 12 characters, that word will not be considered in the total amount of words in the file and it will not be sorted.
* After each word is read, the letters will be sorted and stored into an array containing each
* word's 'signature'. After all the words have been read, words will be printed to the output file on the same line based upon their signature.
*/
public class Anagram {
//Creating constants for maximum words in file and maximum chars in word
public static final int MAX_CHARS = 12;

it compiled fine, can be executed as:
java connectURL
it does not have 'Package' specified

how to create a JAR File I have been watching you tube and it seems like the manifest needs to be remade. I go to the CMD and find my project folder class. I think I need to use do the same for all the classes correct. Well I type jar -cf TictacToeGUIGame.jar *java then I get no such directory. I can see the it worked thought. So do i do this to all my classes and then I will have my JAR program?

View Replies View RelatedActually I use MyEclise to develop and deploy a enterprise project(EAR file). I use Java Build Path to add some other projects and link sources, and added several jar files (as external jar and user library) to my project. (I used J2EE technology and there are some default jar of course )
By myeclise deploying manager I deployed my project on weblogic base_domain and then by weblogic console I deploy it on weblogic. All is set and there is no problem in all steps.
Now I wanna to create EAR file manually, first I created WAR file which included some jsf files and web-inf directory contains classes, lib directories and some important file like web.xml , facec-config.xml and etc.
In classes folder I have .class files which build correctly from .java files, and on lib directory**I copied all jar file from web-inf/lib directory** which created automatically by myeclipse deploying manager on weblogic base domain folder.
I added this War file into EAR file along APP-INF directory which contains all jar files from APP-INF/lib directory on weblogic base domain folder and META-INF directory what contains application.xml file.
When I deploy this ear file on weblogic there is so many error and problems. What is the correct way to create that EAR file.
Lets say this txt file contains 2 lines.
---------
hello
bye
---------
What would i have to do to insert a a piece of text in between hello and bye? I would like for the it to search for "hello", then add a line after it so it would look like :
-------
hello
newtext
bye

I have these 2 methods that work as intended, but i just cannot seem to do what i've stated above.
Java Code: /**
* @param location
* Location of the .txt file.
* @param text
* The String to search for in the .txt file.
