How To Fetch Values Inside Tag / Node Of XML File
Mar 25, 2015
I need to fetch the values inside the tag/node of an XML file.
The xml.file looks like this,
<numeric_values>
<data cc="100" ln="58">2291</data>
<data cc="100" ln="59">2291</data>
<data cc="105" ln="58">2389</data>
<data cc="105" ln="59">2389</data>
<data cc="110" ln="59">1</data>
<data cc="110" ln="57">1</data>
[Code]...
I need the value of cc and ln.
For example the first line contains cc = 100 and i need to fetch 100 and ln = 58 and i need the value 58.

I am generating textfields dynamically using JSTL forEach. Here is the code ..
<c:forEach var="underlyingTickers" items="${underlyingTickersList}" >
<tr>
<td ><input name="underlyingTickers" type="text" id = "underlyingTickers" value="<c:out value='${underlyingTickers}' />">
</td>
</tr>
</c:forEach>
If there are 4 values in underlyingTickersList A, B C, D and E ... I am getting those values correctly displayed in each text field.
However if I submit the form with all these value how can I get it in the bean? I guess I need to have dynamic id or name for each text field. How can generate it?
Note** I dont have Struts framework.. I am using request.getParameter to fetch the values and set into the bean variable.

I am getting errors when I try setting left and right values (which are String types) for my tree.I tried doing something like:
Node node = new Node("Is it human?", null, null);
node.getLeft().setNode("Is it Zelda?");//the first left Q
node.getRight().setNode("Is it Kirby?");//the first right Q
but that gives me a runtime error of "java.lang.NullPointerException" which points to the line 2. I also tried this:
Node node = new Node("Is it human?", null, null);
node.setLeft(setNode("Is it Zelda?"));//the first left Q
node.setRight(setNode("Is it Kirby?"));//the first right Q
but that gives me another error, pointing to the setNode for both lines 2 and 3,plus it wouldnt make sense since both setLeft and setRight takes in Node types, not String types.
Here is my Node class:
public class Node {
private Node leftPt, rightPt;//left and right pointers for Node
private String node, left, right;
public Node(String node, Node leftPt, Node rightPt){
this.node = node;
this.leftPt = leftPt;
this.rightPt = rightPt;
[code]....

Recently we got an issue about file download. We are using below code to fetch the data from backend(DB2) and export to excel.
Before Jan 15 it use to take 2 minutes to download the file (2 MB size). But now its taking half an hour to download.
response.setContentType("application/vnd.ms-excel");
response.setHeader("content-disposition","attachment; filename=Attendance_Report.xls");
We have restarted server, system but still problem exists. We found that there is no code level or data base level or network level issues.
Now we have to see server level issue. What are the factors which effects the file downloading at server level.
We are using websphere 6.1 ,java1.4

I have used netbeans to build my app. So there creating jTable is out of my control as that part was inside auto-generated code. I have just used the jTable.setValue().
My problem is, above method is inside a button click event. Updated values not displaying until the loops ends.

When you select a node in a JTree can you then populate a JPanel based on more information about that node from a file?

I have an issue with variables/attributes scope inside a jsp tag file.
In short, I have a tag with an attribute named "id". If the page using my tag has a variable called "id" (maybe coming from the spring model) and I call my tag WITHOUT specifying the id attribute, inside my tag I still can acces to the "id" attribute that was defined in the page but I don't want this behavior; if the tag is called without the "id" attribute then it should defaults to empty/null.
Example:
print.tag
<%@ attribute name="id" required="false" type="java.lang.String" %>
id=${id}
site.jsp
(...)
The id is: ${id} // <- Prints 'X'
<my:print /> <- Prints 'X' ! I want it to not print anything in that case
<my:print id="Y"/> <- Prints 'Y'
(...)
What I want is to have the tag attributes live only in the tag, without having any knowledge of any variable outside of the tag itself. Is it possible?
My current workaround is to remove the "id" attribute, enable dynamic attributes and with a scriptlet search in the dynamic attributes map for the "id" and save it in a variable with a different name (e.g. "__id").

Below is current process :
We have an application running successfully where we fetch the weight of product currently on Production Line using Java.
All the products on line belong to same order and are of same type.
User at beginning enter the type of product and starts the production line.
Proposed new process: Now client want that multiple type of product can belong to same production order. i.e. on a production line different type of products can come one after other. So we should now fetch the type of product also.
The Question : what are different possibilities in which we can find the type of product. Can java fetch color of a box ? If we use scanner on line that scans the product and sends the color information to Java.
Above is just a possibility. Can there be any other parameters that Java can use to differentiate in type of product ?
Currently we are clueless. What ever are the possibilities in Java we can propose the same to client. Even if that requires additional hardware.

I have a source code here that counts the frequency of alphabetic characters and non-alphabetic characters (see the source code below).
import java.io.*;
public class letterfrequency {
public static void main (String [] args) throws IOException {
File file1 = new File ("letternumberfrequency.txt");
BufferedReader in = new BufferedReader (new FileReader (file1));
[Code] ....
But, let's just say that now I have the following characters in the text file, "letternumberfrequency.txt":
71 geese - 83 cars - 58 cows- 64 mooses- 100 ants- 69 bangles- 90 molehills - 87 noses
The numbers inside that text file would be considered as strings, am I right? But I want to extract the numbers so that I can also be able to count their frequency - not as individual digits but as whole numbers (that is how many "71", "83", "58", "64", etc. are there...). Would using "Double.parseDouble ()" work?

I need to read a csv file from the disk and manipulate the data inside. My problem is that if the csv (excel format) contains "" in any of it's values the whole string line gets saved/displayed incorrectly . For example for the line in the csv file :
1,393275,57319 57321 57323 57325 57327,5_5,200000,393277,57329 57331 57333 57335 57337,3_3,200000,400000,"gi,gi",,,,,,BASS/2.4,,1
it gets read in java as :
"1,393275,57319 57321 57323 57325 57327,5_5,200000,393277,57329 57331 57333 57335 57337,3_3,200000,400000,""gi,gi"",,,,,,BASS/2.4,,1";;;;
instead as :
1,393275,57319 57321 57323 57325 57327,5_5,200000,393277,57329 57331 57333 57335 57337,3_3,200000,400000,"gi,gi",,,,,,BASS/2.4,,1
My code is :
String csvFile = "resources/testcsxs.csv" ;
String l = "";
try {
BufferedReader cz = new BufferedReader(new FileReader(csvFile));
while ((l = cz.readLine()) != null ){
System.out.println(l);
}
What am i doing wrong , how can i read a csv file (excel saved) without getting "" added incorrectly ?

I am trying to display a list fetched from DB in a JSP.
My servlet mapping is:
<servlet>
<description></description>
<display-name>DocumentsServlet</display-name>
<servlet-name>DocumentsServlet</servlet-name>
<servlet-class>com.xyz.servlet.DocumentsServlet</servlet-class>
[Code] ...
The code in the servlet is:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
List<Doc> docs = null;
Connection con = null;
[Code] ....
The code in JSP is:
<%
List<WWDoc> completedDocsList = (List)request.getAttribute("completedDocs");
System.out.println("In JSP == "+completedDocsList.size());
%>
The request is not coming back to the JSP page.
If I change the servlet and have "request.getRequestDispatcher("/pages/ViewCompletedWWDocs.jsp").forward(request, response);" un commented, I get exception "java.lang.IllegalStateException: Cannot forward a response that is already committed".

I am developing my college's project in JSP using jquery to open a magnific popup when user clicks on a link and the in the magnific Popup must be fetched from Mysql and i tried two approaches for this:
1. magnific Popup type is ajax here i passed the variable value in the link of href (after '?') to another JSP page where connection to database is created and queries are written in JSTL to fetch data and show this in magnific Popup .. But i failed in this approach, don't know in another JSP page the data without having database connection is loaded in the magnific Popup easily but not database data..
2. magnific Popup type inline here i need to pass the variable value in the same page between different tags..

I have an assignment on sorting, i kno i can get the sorting down but im having an issue with inputing the 512 ints in a file into an array. the instructor provided us with a file with 4 equal sets of ints. i tried to make my array of size [scan.nextInt()] and it cuts off the last 21 ints. and skips the first int. how can i get all of the integers in the text file into my array? this is what i have so far. if i hard code the array to size 50000 and then try to print the array it compiles but errors out when running it.
System.out.println("Please Enter text file in this format, XXXXX.txt :");
String file =fileName.nextLine();
Scanner scan = new Scanner(new File(file));
int [] data = new int[scan.nextInt()]; <-------here it skips first int
int count= data.length;
for (int i=0; i<data.length-1;i++) {
data[i]=scan.nextInt();
}
System.out.print(Arrays.toString(data));
rst 4 ints in output are: 501, 257, 390, 478...., supposed to be 492,501,390....and last ints are: ....88, 83, 79, 0 and supposed to be :88 83 79 77 76 72 71 71 66 57 56 48 48 41 33 30 23 23 18 17 15 13 9....it replace last ints with 0. why ? and how do i fix this. attached it the text file

I'm having an issue, I have a scanner (Scan.nextLine();) that scans the console for input to fetch the string "word". Then I want to fetch a character using Scan.findInLine(word).charAt(number);. The problem is that the console requires me to write 2 lines in order for the program to move on. I only want the program to scan for a word, and then move on with what it has instead of requiring 2 inputs.

Sample XML:
XML Code:
<Books>
<Book id="1" Name="C#">
<URL>http://localhost/download/M1.xml</URL>
</Book>
<Book id="2" Name="Oracle">
<URL>http://localhost/download/M2.xml</URL>
</Book>
<Book id="3" Name="Archius">
<URL>http://localhost/download/M3.xml</URL>
<URL>http://localhost/download/M4.xml</URL>
</Book>
</Books> mh_sh_highlight_all('xml');
I have to fetch only the book name attribute and use it for display .However say for example ,I have got the list of Books ie(C#,Oracle,Archius) ,passing this value to a method should return me an array of URL nodes value within it.
The idea is to display the book names in a list and then on user selection , corresponding URL needs to be fetched.
Was able to get the loop for traversing the nodes
[java=code]
NodeList nodeList = document.getDocumentElement().getElementsByTagName ("Book");
for (int i = 0; i < nodeList.getLength(); i++) {...
[java=code]
So
a) Display the BookNames
b) Get the corresponding URL's for the particular book if I pass the Bookname

I'm trying to change the value of bricks in my save file and for some reason it can't read the information.
public void addRecords(int brick, int log, int stone, int house){
x.format("%s%s
%s%s
%s%s
%s%s", "brick", " "+brick, "log", " " +log, "stone", " "+stone, "house", " "+house);
}
This writes information to my files. ^
public void addResource(String resource, int amount){
openFile();
readfile check = new readfile();
switch(resource){
case "brick":
[Code] .....
In my case "brick", It doesn't set the value when I try to read it. Here is the readResource method.
public int readResource(String resource){
System.out.println("Looking for " + resource);
String res = resource;
openFile();
while(x.hasNext()){
[Code] ....
Short version:
brick = check.readResource("brick");
This doesn't set brick to any value.
