Java Convert String Of XML To Document Object Is Null All The Time
Apr 15, 2014
I am trying to parse a XML string into `org.w3c.dom.Document` object.
I have looked at solutions provided [here](xml - How to convert String to DOM Document object in java? - Stack Overflow), [here](How to create a XML object from String in Java? - Stack Overflow) and a few other blogs that give a variation of the same solution. But the `Document` object's #Document variable is always null and nothing gets parsed.
Here is the XML
Java Code:
XMLMappingValidator v = new XMLMappingValidator("<?xml version="1.0" encoding="utf-8"?>
" +
"<mapping>
" +
"<container>
" +
"<source-container>c:stem.csv</source-container>
[Code] .....
When I call Java Code: **v.getXML().toString()** mh_sh_highlight_all('java');
I get Java Code: `[#document: null]` mh_sh_highlight_all('java');
Clearly, the parse is failing. But I don't understand why.

Consider in a Document if a String " Hello" is Encoded and stored as "XYZAB"
I want to search the text on document for a word "Hello" and Replace the word with "HelloWorld"
The Program will encrypt the word "Hello" and Search the file then return the encrypted code as "XYZAB" Found
Now i have to replace the word "Hello" with "HelloWorld" in encrypted form so that the Letter "XYZABEFGHI" is replace in the place of Hello where "World" is encoded as "EFGHI"
Now the Problem is If there is more number of occurrence of the word "Helloworld" exist in the file... How can i Replace only one particular occurrence What can be done to select the particular occurrence.
I have attached my java program for Encryption along with this mail for your ease of use.
I am using a static method to convert a string to an Integer object. Next using a instance method to convert Integer object to an int.
Compiler is giving me two "cannot find symbol" errors:
One pointing to the dot operator between "Integer.valueOf(s)"
The other pointing to the dot operator between "obj.intValue()"
I have latest JDK installed: jdk-7u51-windows-x64.exe
Looks like JCL installed correctly with rt.jar file located in "lib" directory under "Program Files"
Following is source code:
Java Code:
public class StringToInt { public static void main (String args []) { String s = "125"; Integer obj = Integer.valueOf(s); int i = obj.intValue(); i += 10; System.out.println(i); } } mh_sh_highlight_all('java');
I am suppose to have a method called save() which should marshall the list of computer parts in the right panel to an XML file. In reverse, another method called load() that should unmarshall the saved XML file back into an object. So basically, the Save event will call save() method and save the list of parts in the right panel to an XML file. The Load event should clear the right panel, and call load() method. When load() is called, it should display the unmarshalled data in the right panel. I got "Exit" to work.
I'm having hard time figuring out the "Load" and "Save" parts though.
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class PCParts implements ActionListener{
I looked on other examples which have collection of object but I have this extra top level object "AvailableDeliveries" not sure how to handle that level.
I need a Java algorithm that converts a string of numbers into text. It is related to how a phone keypad works where pressing 2 three times creates the letter "c" or pressing 4 one time creates the letter "g". For example a string of numbers "44335557075557777" should decode where 0 equates to a space.
I have an input text file as file.txt where, it consists of only real values separated with commas, and arranged as rows as columns as mentioned below :
the number of rows is 100 and the number of columns are 9, that is they are fixed.Above is just an example, the file consists of decimal values.What I require is for each column of values I need to find out it's average or mean, that is in above example,
for 1st column:(1+1+2)/3 for 2nd column(2+4+4)/3 for 3rd column(3+7+5)/3,,,,,,,like this till the last column.
So I need to take the input from the .txt file, calculate the column average of each column and the average of each column must be displayed as output. I have done a bit of coding, but it is giving a run-time error as NullPointerException.I will forward my code as attachment, the reading of file, is done as string in java and then it must be converted to double values, also to read the comma separated input from a file I have used the split().
Explain anonymous objects with example clearly...i read some where anonymous objects advantage is saving memory...it is benificiable when there is only one time object usage in our program..i can't understand one time usage of object ....i know anonymous objects but i don't know in which context we use them in our programs...i did the anonymous object program with my own example but i can't differentiate this one with normal object..i'm providing my own example below
//anonymous object public class anonymous { int x=10; int y=25; void display() { System.out.println("anomymous");
I have a string value returned from a background tool that will range from 0 to possibly terabytes as a full number. I want to format that number to use commas and to reduce the character count using an appropriate size modifier (KiB, MiB, GiB, etc). I've tried converting the string number to a Double value using Double.parseDouble() and then performing the math based on the size of the value with this code:
I have a class of Date with a constructor with 3 parameters in it. Those 3 parameters are int data type just to enter month, year, day.
I have another class called Author which has a constructor of Date diedDate; as a parameter passing to the Author constructor.
I was asked to call the Date parameter is null, call the default constructor but I thought for the Date parameter I could only enter something like 0,0,0 instead of typing in null, null, null because null is for String data type isn't it?
I've been assigned to create a Black Jack game with a gui. In this game I've created a seperate Player and Dealer class, and both initiated them, however when I try to call a Player object in a certain way I get a null pointer reference. (It should be noted that the Player object is an array)
public void runGame(){ while(running){ while(dealer.getPoints() <=19){ int count=0;
[Code] .....
And this is how I've initilized the Player class in the constructor
Player[] players = new Player[numberofplayers]; for(int i=0; i<numberofplayers; i++){ players[i] = new Player(i); players[i].setDeck(d1); gui.add(players[i].getPanel()); }
What I don't get is if I change players[i] to dealer, it works fine.
I created the WSDL first in RSA and then created the java bean skelaton from the WSDL. There are a couple of dateTime fields in the WSDL that are created as GregorianCalendar objects.
When I test with SOAPui and the date fields are passed correctly, everything works great. But when there is an invalid date format or anything else in the SOAP request, instead of returning a Conversion exception or some other validation exception, the field is passed as a null to the request object in the SOAP IMPL. Should't this return an exception?
Sample requests inputs: <endTimeStamp>2014-01-28T01:30:14.474Z</endTimeStamp> - Date <endTimeStamp>06-FEB-14 01.51.00.000000000 AM</endTimeStamp> - Null <endTimeStamp>Any other string be it a date or not.</endTimeStamp> - Null
The question pretty much says it all, but I tasked myself with creating a program about lemurs. There are multiple class files in this program. In the below code snippet, I have my TreeLemur.class which extends to the Lemur.class which extends to the Mammal.class. However, when I create a Tree Lemur object in the main program, it is returning null consistently from certain methods. What am I doing wrong here?
TreeLemur.class :
public class TreeLemur extends Lemur { private String groupSize; private String diet; private String fur; public void setGroupSize() { groupSize = " Group Size: Large"; }
[Code]...
As of yet, I'm just trying to get Tree Lemur working properly to continue with creating the other if-branches within the main program.
My current calculator (currently available on my site) launches your default webbrowser with the CalculatorHistory file allowing you to print through your browser, but I been working on self contain the html page in a the JEditorPane which is great it does what i want, so I started working on the printing side and I am stuck...
The code I have was from a example (modified) but when I run the code I get the following error:
Exception in thread "main" java.lang.IllegalArgumentException: services must be non-null and non-empty at javax.print.ServiceUI.printDialog(Unknown Source) at gcclinux.co.uk.PrintReport.main(PrintReport.java:28)
The Line 28 equals to PrintService service = ServiceUI.printDialog(null, 200, 200,printService, defaultService, flavor, pras);
