Strategy To Change File Extension And Read Library
Sep 19, 2014
I need to be able to select a file (compressed), change its file extension (to zip) and load all its content, preferably as objects. If it makes things easier one can assume all these files to be of the same type.
The content of the zip file are placed in folders, known Beforehand which might make things easier.
I am trying to write a webservice class which actually handles multipart requests. T client will try to upload zip or tar.gz files which may be upto 1GB in size.
I dont want to validate the extension i client side.
I want to validate the file extension in server side and discard the request before the file is uploaded.
I am trying to make a Library that will read some Input Files from a File . Like When We Enter Nuber from a System.in
1 2 45 667
77 34
and then store these values in int[] array
What I want is I Save all these values in a File and at Run time pass path of that file to command line arguments and then int[] array will be initialize using that
I want to programmatically change the default program which an extension is opened in. So .resantic extensions for example to run in my jar file when I double-click on it. I know i need a bat file or exe file because i can't directly run the jar file. But i was wondering if its possible to run it if its an executable jar file. Else i can just make a bat file that runs my program. Also how can i on double click send the path to the file that was clicked in the args[] array so i can open the actual file aswell instead of just opening the program?
I'm getting an IllegalArgumentException returned when I try to get a file using guava library.
I previously had the function working when the file was in a different location, before I switched to running JBehave, my steps run but it fails to find the resource, even after I've moved it.
The code being executed is (this worked previously before using JBehave):
The file I'm looking for is in the root folder for src/main/resources and also src/test/resources, previously I had it within a completely different location before I switched over to JBehave. I've tried it within a subdirectory in the same locations too.
I've recently updated the pom.xml to try to include the location required.
I have a program that allows the user to select what type (i.e. tif, jpg, sid) of file they have to load. I use a JCombo box for the selection type. I send this JCombo box string to my ElevationConvert class. What I want to do is check to see if that extension the user selected exists prior to converting it. If the file extension does not exist, I want to pop up a window (JOptionPane) stating is does not exit. I have tried suggestions found on this site, but does not seem to work for my application. The program works with (Process cN = Runtime), if I try not to check for the extension. But when I add the check for (If, else), it bombs. This executable runs in the main folder. The file extensions are in a subfolder called Ned.

i want to find an embedded file extension i.e suppose if word file is there in that excel is also included then is should detect both file types word n excel and is is it possible to find an embedded file type.
I am currently working on an application with java and I want to do is upload and download details in .xlsx file. Uploading process is successfully worked but the problem is that when I download the file .xlsx with details at opening the file it gives me the following message :
Excel cannot open the file '(filename)'.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.
I'm trying to make a search engine that will search my computer given a path with any options i decide. So if i decides to look for the file name "resume" with extension "pdf", it will give me the files in the directory, including subfiles.
import java.io.*; import java.util.*; import java.text.*; public class mySearch { private final static int path = 0; private final static int name = 1;
This is a summary of our front-end development process:
- designers create PNG mockups - UXers create HTML mockups - developers create final JSF
Now, these HTML mockups are pretty complete. They use all our in-house JavaScript widgets, production CSS files, responsive design, accesibility requirements, SEO-friendly code, proper semantics etc. So basically the final HTML we need from the JSFs has to nail these mockups, otherwise widgets might not work, styles might not appear correctly, accesibility errors might crop in and SEO might suffer. The developers tend to have limited experience in HTML/JavaScript/CSS/accesibility, especially compared to the UXers, so the less they can do to screw up the HTML the better.
I am using Spring to develop a web application.I have used JQuery ui in HTML page it is working fine a Dialog box appear with JQuery effect.But When I use the same procedure in jsp it is not working.Here is my code of jsp file
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Login Page</title> <style>
Finding a strategy that allow process 12 millions of records in less than 1 hour. Each record can be modified by business rules. In this process are performed insert, update and select in other 3 tables.
The end result of this process is update monetary fields (for the calculations is used BigDecimal) of records in another table.
This process is part of the migration of Cobol to Java/Oracle. In cobol this process takes approximately one hour. Is it possible?
I am working on some enhancement on application. I have a requirement. The flow is as below
In a jsp file one selection dropdown exists and a body. Selection dropdown is written as custom tag library and is included in jsp file eg tag.tld whose code exists in tag.java code for other parts of jsp are written in that *.jsp file itself. eg test.jsp
i.e test.jsp calls tag.tld to include selection dropdown
I now want a hashmap created in tag.java to be available in jsp file and I want to use it in one of the javascript function available in same jsp file for validation
I want to work on a project related to MMO real-time strategy social game as a college project but i dont have enough knowledge on it starting from 3d object coding to server.
Also i would like to know what are things to be cosidered as its an online game whether the camera angel affect what are problems that might occur and how to outrun it. How to split the server so that in one server depending upon the geo-location some number of users will be connected and will be splitted in different servers depending on the location
I want the actions to be cloud based but the actions of the characters will be coded within the game and in every server maximum of 100 users can connect.
I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...
The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data.
Here is the base Product class that must be used to create the objects for the array.
public class Product { public String pName; public String stringName; public double price; public int quanity;
[Code] .....
And then here is the data from the text file that i must extract to use to create product objects.
These continue for about 40-50 entries, they are not separated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name separated with spaces, then price after a comma, then quantity after the second comma.....
New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows
(1) The original list of N numbers from the input file, (2) The original list of N numbers printed in reverse order of how they appear in the input file. (3) The sum and average of these numbers, (4) The minimum of all the numbers, (5) The maximum of all the numbers.
Well my code is supposed to ask for an input file and then (ex: input.txt), read the input file and create an output.txt file with the anagram for the words in the file. Also it should be displayed on the screen. However my code doesn't display the anagram on screen or the output file!
/* This program will read a file given by the user, read the words within the file and determine anagrams of the given words. If the file that the user inputs is empty, then the program will output "The input file is empty." * The program will read the file line by line, counting the total number of words read. If there are more than 50 words, "There are more than 50 words." * will be printed, and the program will terminate. After each line is read, the words in the line will be separated,punctuation characters will be removed, and upper case characters will be switched to lower case. * If any word is larger than 12 characters, that word will not be considered in the total amount of words in the file and it will not be sorted. * After each word is read, the letters will be sorted and stored into an array containing each * word's 'signature'. After all the words have been read, words will be printed to the output file on the same line based upon their signature. */
public class Anagram { //Creating constants for maximum words in file and maximum chars in word public static final int MAX_CHARS = 12; public static final int MAX_WORDS = 50;
I am trying to create a file browse option in my jsp and later after browsing, all i want to do is to read that file in my jsp without saving it into that database so that i can perform encryption for it and save that encrypted file later into my database. please provide reference link so that i can refer to some applications and and move ahead with my work.
I am working in JSF and I've forgot few of the basics :'I use eclipse IDE to develope JSF projects. When I used to create a JSF file, it's extension is basically .jsp and when I ran that file in server .jsf extension used to be displayed in url. But recently, when I did the same thing I got .jsp extension in browser. in web.xml
when url-pattern is the following, .jsp extension is shown, eg: FileName.jsp
even if I change the url-pattern to abc or xyz, the webpage url is shown in that format. eg: FileName.abc this is the actual scenario to specify extension of a jsf page, or is this an error.
I am trying to write to a file but everything I have tried doesn't seem to work. What I want to do is read a file and then output back to the same file on a new line. The text file contains the sentence "Java is a programming language".
import java.util.Scanner; import java.io.*; class HW1B { public static void main(String[] args) { Scanner fileIn = null; try { fileIn = new Scanner (new FileInputStream("text.txt"));
[Code] ....
These are the errors :
HW1B.java:19: error: no suitable constructor found for Scanner(FileOutputStream) fileOut = new Scanner (new FileOutputStream("text.txt")); ^ constructor Scanner.Scanner(Readable) is not applicable (argument mismatch; FileOutputStream cannot be converted to Readable) constructor Scanner.Scanner(InputStream) is not applicable
[Code] ....
Note: Some messages have been simplified; recompile with -Xdiags:verbose to get full output 2 errors
I am trying to read a file and input each line of the file into an array. I have not set the array size as I was hoping to fill the array using a while loop. Unfortunately the scope of the array does to work inside the while loop so I am being told that the array 'students' has not been initialised even though it has just outside of the while loop. Is it possible to do what I am trying to without having the array initialised in the while loop as surely the array will be reset every time if it was in the while loop? Here is my code:
public static void students(String file) throws FileNotFoundException { try { File studentInfo = new File(file); Scanner input = new Scanner(studentInfo); String[] students;
recently I noticed that most of the Sun site pages have the extension .jspa, some even have .xml.So just curious about it because I don't know about jspa but as far as I know of xml, it is not rendered by browser like the way we see on Sun site.
