My xml file is look like this how to get data from this file through tag name.
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 ?

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.
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 using apache-commons-fileupload to get file from client to the server.(using JSP and Servlet).
JSP/HTML
<form method="POST" action="GetFile" enctype="multipart/form-data">
<input type="file" name="datafile">
<input type="text" name="text1">
<input type="submit" value="Next">
</form>
Servlet: GetFile
System.out.println(request.getParameter("text1"));
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.
--> Or is there any other problem in my code?
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;
Java Code:
Class Hops{
String Name;
float Alpha Acid;
float Beta Acid;
};
Class Malt{
String Name;
float extract;
};
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 .

My issue is that the 'str' value is not initialized, but if I initialize it, it ruins the code. I'm not sure what to do in the situation.
write a program that will take in a URL as input and then search through the text on that webpage to pull out relevant data.Essentially, my plan was to have the program search the webpage on certain strings and then find and record the numbers on the same line to compile into another file. Luckily, all of the data I need are in tables on the webpage so I assumed that would make it easier to get the data.
The problem that I am facing is that I do not know where to start. I have been searching the web for answers to this but, unfortunately, the only thing people tend to recommend is using an HTML parser. This would not work since HTML code is not what I am looking for and does not include the data I seek.
I am new to Java programming and how to store data in Java.....Here is a example:Unique number, description, qty in box, price...There are thousands of these in my list. What would be the best way to store them.

I've created a method to calculate the ratio of one vowel to another, but I was hoping to get some feedback on another way I could approach the problem. The first bit of code is to find the vowels and assign them to an array ( for me, it seemed the easier thing to do in order to easily access the data). In the other bit of code, I have a method with two arguments (the vowels) to calculate the ratio.
public void findVowels(StringBuilder message, String delimiter) {
subString = message.toString().toLowerCase().split(delimiter);
vowelCounter = new int[5][subString.length];
// Remove all whitespace
for (int index = 0; index < subString.length; index++) {
subString[index] = subString[index].replaceAll("s", "");

My professor like us to make a salary, taxes and etc exercise. which we should type the name first then, input salary. then if we input the amount 8000 or higher. the system will ask another question about the marital status. and that is it.
My real problem is when we input 5000-7999 the system should ask a different question, stating do you want to pay for your premiums and a follow up of yes and no choices. if we input 0-4999 the system will just state that it is your current salary.... etc..

I have a class which connects with database and fills object with data. Method looks like this:
//in database class
void getData(anObject a, int id){
//connects with database
a.field1=get...
a.field2=get...

//disconnects
}
Now I want to use this method in anObject class, but I can't call it because I don't have created object jet. Is there any way to call this method?
I was wondering, for both a web based application and a normal Java program, should I just open up an I/O every time I need certain data, or am I better off just loading all the information into my program at start up?
View Replies View RelatedWrite a program that allows the user to enter students names followed by their test scores and outputs the following information(assume that the maximum nmber of students in the class is 50; if the number of students is less than 50, to indicate the end of input data, after entering the last students data, on a line by itself, hold the ctrl key/press z and then press the Enter key):
a) Class average
b) Names of all the students whose test scores are below the class average, with an appropriate message( youre below class average)
c) Highest test score and the names of all the students having the highest score.

I need to generate a bar chart given the data that is in main. The relative performance of each sorting algorithm with respect to time, number of comparisons, and number of swaps for each data set (e.g., 50,000 –400,000 random integers). Each algorithm will have 5 bars corresponding to the 5 data sets. The height of these bars will depend on the performance of the algorithm for that data set.
I know how to write a bar with normal values like integers but for this I'm not sure because the values for instance comparisons and swaps are not given they are calculated. I just need to know what steps to go about doing that, you can even express them in pseudocode or even just explaining it I don't need the code, I think. Here is the main
public class Main {
public static void main(String[] args){
int t= 50000;
int t2=100000;
int t3=200000;
int t4=300000;

View Replies View RelatedI'm having an issue returning data from a constructor. This is an assignment, and the specifications were that two classes are to be used, one for the variables and assigning methods, and one for the main method and the printing. This app compiles, but returns "0" for the isbn number, and I'm sure it's because I'm not doing something right with my constructors. My code is below

I want to define this data structure , I show you an example
"first street",{{1,40},{43,45},{34,26}},
"second street",{{14,41},{42,5},{3,46}},

I wrote in this way but it doesnt work :
Map<String,ArrayList<int[]>> Street=new HashMap<String, ArrayList<int[2]>>();
how can I extract data from two different files but produce one output. For example, the first three columns are from text_file_1 and the last column (the last foruth column of the output) is from text_file_2.
