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?

Modify the Improved Fibonacci application to store its sequence in an array. Do this by creating a new class to hold both the value and a boolean value that says whether the value is even, and then having an array of object references to objects of that class.
Did I just need to declaring the variable in other class (for boolean value and the value itself) or else ?
Here is the code for ImprovedFibonacci.java
Java Code:
class ImprovedFibonacci {
static final int MAX_INDEX = 9;
/**
* Print out the first few Fibonacci numbers,
* marking evens with a '*'
*/
public static void main(String[] args) {
int lo = 1;
int hi = 1;
String mark;
[Code] ....

I have an html form with 200 input fields of type text. The first input field contains the name of a book author and the remaining 199 fields hold each a title of a book that he or she has written. I also have a servlet that processes the form data and sends it to a file. The entered data is restricted to a combination of the characters "a...z A...Z". how do i go about with creating my html page. The input fields are just too many, how to retrieve the 200 values in servlet.
<html>
<head>
<script>
var k;
function testField(Expression){
k=1;
var str1="abcdefghijklmnopqrstuvwxyz ";
var sor=Expression;

I have a java query like this
query ="Select major_career.Major_Title, career.ISCOTitle,career.FS.... " //only partial,
// I swear the query is correct
resultSet = statement.executeQuery(query); //this executes it
relArr = new ArrayList<String>(); //don't worry it is intialized
In the code below I tried to store the resultset components into the arraylist
int j = 1;
while (resultSet.next()) {
while(j<=numberOfColumns){
relArr.add(resultSet.getObject(j).toString());
j++;
}
} // end while
I am not sure whether the arraylist is able to store the result set because when i try to display it like show below it only shows some rows and only the first column
Iterator it = relArr.iterator();
while (it.hasNext())
{
System.out.println(it.next());
I want to manipulate the resultset results in my program by copying the resultset values to other datastructures.

I am making a program to read data from excel files and store them in tables by their IDs. I have managed to read all the data from excel files as a string and store them in a table. But my project is to store them in table by ascending IDs. I have created the comparator in another class but when i call it in the main class nothing happened. The data that I have to store is like the below:
ID Name Salary
50 christine 2349000
43 paulina 1245874
54 laura 4587894
23 efi 3456457

The codes are below:
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;

I have a very simple HTML form with a textField for a name, and add button to add the name to a MySQL database, and a sort button to sort the names in the database and display them. I almost have it working, however when I hit the "sort" button; I get the message that appears after a user clicks the add button along with the sorted list of names. It looks like this:
Please go back and add a name or sort.
Bill Jones
David G
Debbie Downer
Jane Doe
Joe Smith
John Doe
Mike Jones
Paul Smith
Susan Jones
What I have to change on my code to make just the list show up by itself when the user clicks sort?
My servlet code:
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.sql.*;

I tried something like that:

matrix [i][j]=textFile.get(i).split(" ");
//System.out.println(matrix[i][j]);

I written java code in JSP to display data. I know it is bad practice. Actually my Business-service communicates with DB and returning data in the form of MAP. I don't have beans Because the fields in DB is dynamically changing. So, for now I'm retrieving Data by writing Java code in JSP. Is there any other way to display data without writing java code in JSP?

public class InputFileData {
/**
* @param inputFile a file giving the data for an electronic
* equipment supplier’s product range
* @return an array of product details
* @throws IOException
*/
public static Product [] readProductDataFile(File inputFile)
throws IOException{
// YOUR CODE HERE
}
This code is meant to be used to read a text file and store the data in an array of type Product[]. I know how to read in a text file and have it sort it into an array, but I've never seen code laid out in this fashion before (specifically "public static Product[]", and I'm unsure how to work with "(File inputfile)". I've looked all over the place but can't find any examples of anything like this.
Also, the code given cannot be changed, as it's that code I have to work with.
I still don't understand how to use it as a whole. For example, do I read the file in the main and have this method read that in and output to the Product class? Do I read the file in this method? I can't work out how to make this work when I have to use this method.

I'm getting ready to code a program that takes record of items loaned and return in a table. I want more than one user to access the program to be able to update the data in the table. For instance, if one user added 5 new items to the table, all other users would be able open the program to see a modified table with 5 new items. Was looking for some advice and was wondering if implementing a database would work best.

How i can get the data from a file, for a key that have multiple values without using split method and i want to store that data in an array
file name:"new.txt"[contains below data]
Name=google.com, yahoo.com,facebook.com
Attachment=abc1,abc2,abc3
I am successfully able to do this using following code
Properties props = new Properties();
String configFilePath = (Cjava_confignew.txt);
props.load(new FileReader(configFilePath));
String TestName = props.getProperty(Name);
String test[] = TestName.split(,);
Now i just want to store the values for key "Name" in array without using TestName.split(,); but i am not able to do this.

I am currently working on a module where huge amount of data needs to be sent to the weblogic server. The limit on Weblogic-> Server - > Protocols is 10MB.
The huge data is coming when i try to add more than 20 rows to the Ajax request.
There are possible two solutions for this
1) Increase the limit on Weblogic server to 1Gb which might lead to server crash when two or more users are trying to add 100 records at the same time.
2) Send memory in the form of chunks of (length of a row) every time I add a row. Store this in session and upon form submission retrieve from session. This cannot work if there are more than 20 users doing load testing as increase in session data decrease performance gradually.
I need that data passed to my server without any performance or errors.Currently its showing weblogic.socket.MaxMesssageSizeExceededException and RequestURI too long errors.
