How To Escape unwanted Special Characters In String Data While Converting Into XML Data
Mar 7, 2014
I'am trying to converting string data into xml data using xml beans and StringEscapeUtils.This is work fine but in one case it if the data contains special characters.
Code snippet
--------------------
import org.apache.commons.lang3.StringEscapeUtils;
import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlObject;
public class ParseXMLData {
public static XmlObject parseXML(String stringXML) {
XmlObject xmlObject = null;
[Code] ....
success case
---------------------------
i/p------<aaa><bbb>This converts string to xml</bbb></aaa>
o/p---<aaa><bbb>This converts string to xml</bbb></aaa>
Failer case
-----------------
i/p----<aaa><bbb>This fails if it contains < symbols</bbb></aaa>
expected o/p----<aaa><bbb>This fails if it contains < symbols</bbb></aaa>
Observed that it converts < to '<' but as per xml rules, if data contains '< ' it fails. I want to convert staring and end tags to xml format and if data in b/w middle of starting and ending tags do'n need to convert it. How to do it.
<esi:assign name="searchfor">'''someval like < or >'''</esi:assign> . Now on the basic of request param i want these tags should render with value < or > on the basis of what is inside tags. I applied the below code but didn't work. Any Idea. <c:if test="${testval}" > <jsp:text><![CDATA[<xmp>]]></jsp:text> </c:if> <esi:assign name="searchfor">'''>'''</esi:assign> <c:if test="${testval}" > <jsp:text><![CDATA[</xmp>]]></jsp:text> </c:if>
This is my textbox can i include in my tetxbox that it will no accept special characters?
Can i configure it there? like maxlength="20" w/c is character limit is set to 20, not allowing special characters be configure like that , character="speical is not allowed" something like that?
import java.util.Scanner; public class PassCode { public static final String SPECIAL_CHARACTERS = "$,#"; public static void main(String[] args)
[Code] ....
I'm having trouble with the code using char[]c, for the special characters. Every thing else seems to work correctly, expect for the special characters.
first row abc has width as 6 and FLof as 2 in file A, so it occupies position 2,3,4,5,6,7 accounting to 6 position so represented as abc_7_2 in file B
Now row three of file A has duplicate of abc so now the new offset will be previous offset plus one ie. position will start from 8 and it goes as follows 8,9,10,11 so represented as abc_11_8
This will create unique and informative names, the same goes with other rows :
I get an error when I try to divide 500 miles by 25.5 gallons
Exception in thread "main" java.lang.NumberFormatException: For input string: "25.5" at java.lang.NumberFormatException.forInputString(Num berFormatException.java:65) at java.lang.Integer.parseInt(Integer.java:580) at java.lang.Integer.parseInt(Integer.java:615) at Mileage.main(Mileage.java:42) Java Result: 1
public class Lab07 { public static void main (String[] args) { System.out.println(convertToInt("123")); } public static int convertToInt(String str) { int conversion = 0; int i;
[Code] ....
The only methods I am aloud to use is length and charAt, which I have done. I see why it is returning a 0 at the end of the value returned, its because I set my int conversion = 0. If I just declare it I get a compiler error that it must be initialized.
I would like to understand how does multipart/form-data works during file upload scenario's, Does it chunks the data from client to server while transferring the files ?
Is there a way to inform the Entity Manager or force the JPA provider to reload data from the database? The scenario could be data being updated by a store procedure or direct SQLPlus maintenance, without restarting the Application Server, the JPA need to load the newly updated data from the database.
I think the current JPA API is not enough. The void refresh(java.lang.Object entity) from EntityManager need to pass in the Entity object, I will like to know how to refresh the entire JPA Entity data after the physical table data being update from backend.
By using FileReader, FileWriter and their constituents, I am creating a file to contain employee information ( name, age, hours, etc. ). The user is to input all of the data on a single line and we were asked to implement StringTokenizer to assign that data to the file. I have never used the StringTokenizer before, but I have a rough idea how it is to function. I used pw.println to test what I have so far, now I would like to let the user build the initial file with the "first employees" of the company, and then view the file, and then go back and append new employee data to that same file. My question is, how can I take the user input as a StringTokenizer and add that to the file?
In the for loop below, I thought I would see if it would work, but it does not. The loop only executes once and does not allow me to enter data.
public class Records { public static void main(String [] args) throws IOException { Scanner input = new Scanner(System.in); FileWriter fw = new FileWriter("dbs3.java"); BufferedWriter bw = new BufferedWriter(fw); PrintWriter pw = new PrintWriter(bw); System.out.println("NEW EMPLOYEE DATA SHEET"); System.out.print("Number of new employees: "); int number = input.nextInt();
I am able to upload the file to the server, but I am not able to get the value of text1 in the servlet (I am getting null value of text1 in the servlet), I need this textfield in the form to submit some additional information while uploading it to the server.
--> Is enctype="multipart/form-data" option of form doesn't allow other form data to be submited? if it doesn't allow it then what are the other options I have to send this additional textfield to the server.
I have written several simple data classes that I serialized manually by converting to text. At this point I need to serialize a more complex data structure. which will include lists of the simpler elements. Can serialize store and reconstitute this type of structure automatically or do I need to do this one manually as well? Consider the pseudocode below for a clarification of my question;
Class Recipie{ String Name; CList HopList; CList MaltList; };
CList RecipieList; mh_sh_highlight_all('java');
I read the article on Serialization presented at tutorial point, but the example only showed a simple class, not lists of class members. What I want to do is serialize RecipieList, which consists of a CList of Recipies, which in turn consist of CLists of various ingredients.
I have a program which consist of several classes. The program reads a pom file and parses the data and then writes the data to a static table. The issue I'm having is with writing my LIB file data to my table. In the HtmlDataTable Class Im trying to write the files that are read in the lib directory to the table. My table currently consist of 3 columns (missing jar files,Lib Directory files, and POM file data) currently Im only able to write the missing jar files data to my table. In the HtmlDataTable class there is a for statement where I write the missing jar file data to my table. Im also trying to write the contents of the Lib directory within this statement as well. This is where I'm having my issue. My other classes consist of a SAX parser which parses the xml file, a class that creates my static table and a class that compares the jar files in my lib directory to the jar files in my pom file. . Theres a lot of code so I included the parts I felt were useful. If needed I can include the other classes as well.
public class ReadPomFile extends DefaultHandler { public static void main(String[] args) { try { // obtain a SAX based parser to parse XML document
I am creating a program where it reads the data inside a file and then places this data into arrays. The file I created has numbers 1-30 in it, file named, testing1.txt .
This program accepts Student ID numbers, Name, and grade point average. The problem I am having is with the if else statement that compares id to studentID[x]. I have tried to compare using if(id.equals(studentID[x])) and also I have tried using if(id == (studentID[x])) as shown in the code below. I keep getting incorrect results though.
//FILE: StudentIDArray.java import javax.swing.*; //Used for the JOption dialog boxes import java.util.*; //Used for Scanner input
A group of my classmates and I were discussing strings. We were asked, "What circumstances would you want to convert a text string to numerical data?" but we couldn't think of any answers outside of counting characters within the string for various applications.
I have a double primitive and gave it a huge value. I am curious if valueOf could ever potentially cause data loss. I tried a simple test and it seems it never loses any data:
Java Code:
public class DoubleStringTest { public static void main(String[] args) { double val = 1029.129348558634; System.out.println(val); System.out.println(String.valueOf(val)); } } mh_sh_highlight_all('java');
I'm just trying to append new employee information to a previously created file. When I type yes to add new employee and enter a string, the data does not appear in the file.
Java Code:
public class Records { public static void main(String [] args) throws IOException { Scanner input = new Scanner(System.in); FileWriter fw = new FileWriter("dbs3.java", true); BufferedWriter bw = new BufferedWriter(fw); PrintWriter pw = new PrintWriter(bw);
I have table data I'm trying to read . However one column is populated with the word "null". I guess java does not like dealing with the word null and throws errors.
When I try a block like : if ( rsrow.getString(insCol) = "null") {
I get and error .
If I try :
cmp = rsrow.getString(insCol);If I try:If I try: if (cmp = "null") {
I get an error
If I try to use a replace function like:
System.out.println(cmp.replace("null", "0"));
Just to see if replace works I get and error.
What is the BEST way to replace this string value with something like "0" when I come across it with out jave throwing an error? I want it such that every time I come across the word "null" I can repalce it with "0".
I'm getting a Base64 encoded String of raw PDF data from a web service. I have to use this data display the PDF in a PDF viewer (I happen to be using the included 'ThinkFree PDF Viewer' since I'm working on an Android application, but the Android forum doesn't seem to get much traffic, so lets generalize and say any PDF viewer will do).
My code:
File file; FileOutputStream outputStream;
public void createFile() { try { File path = new File(getFilesDir(), "PDFs"); if (!path.exists()) { path.mkdirs();
[code]....
The error: Error opening file. It does not exist or cannot be read.

I have created an enumerated data type that represents months. In my program I have asked the user for the month. I hold the month entered by user into a string variable. From that string variable I'm trying to display the month using my enumerated data type. I know I can use if statements, but is there another simple way to do it?
import java.util.Scanner; public class demo { //Enum class called month that has constants in it representing months enum month{january,february,march,april,may,june, july,august,september, october,november, december};
I am writing a code in which a user inputs data as a string and that data must be verified as a valid number. A valid number is anything from 0-100. Then all valid numbers are converted into double numbers.
I am having trouble in how to write the validation part of the code.
Is it suppose to be an if, else statement? And if so how is it suppose to be validated?
I am currently trying to make a calculator in Java. I want to use the String split method to tokenize the string of characters inputted. I thought I was using the String split method wrongly, because I had surrounded the characters I wanted to delimit with square brackets. However, when I removed the square brackets, the code threw an exception when I pressed the equal button. The exception was a PatternSyntaxException exception. Am I using the String split method wrongly? And why is the exception thrown? Here is my code:
import javax.swing.*;//import the packages needed for gui import java.awt.*; import java.awt.event.*; import java.util.Arrays; import java.util.List; import static java.lang.Math.*; public class CalculatorCopy { public static void main(String[] args) {
I'm trying to loop through a string and depending on the character, add a JLabel to a game. The problem is the character 'L' represents a lantern but is also used in the reply the game gives which is "LOOKREPLY". I've tried to use some code to ignore the LOOKREPLY bit but it's not working. Here's what I've tried.
But the first image on all of the JLabels is always a lantern, which is what L represents. As it's only 1 lantern this leads me to believe that it's ignoring the first 'L' but for some reason it's not ignoring the 'L' at the end of LOOKREPLY.
