I have a jsp form that has a drop down option for a user to select. I would like to know how to have a pre-selected option that has been retrieved from my database or provide a default option if none has been selected by the user. My form allows a user to update a record in my database and what I need to achieve is when a user is updating an existing record they do not have to touch the drop down box if the do not need to change that option.
Here is my current form below form method
="POST" action='UserController?action=edit&albumId=${album.albumId}' name="frmAddAlbum">
<label for="album id">Format : </label>
<select name="action" selected=<c:out value="${album.format}" /> >
<option value="listUser">CD</option>
<option value="listUser">Tape</option>
<option value="listUser">MP3</option>
<option value="listUser">VINYL</option>
</select>

I would like to know what is the best way to upload & download files using Servlets/Jsp's . In some websites I have seen example using third party API(by oreilly). Is it better to follow any third party or can we do it just by using I/O streams. What are the steps of uploading files. And where do we need to store files once the user uploads ,Database or server??

Most of the answers I found on the internet either dont meet this requirement or load all file names into an array which can consume too much memory when no. of files = 20,000+. how I can do this. Is there also a way to keep track of new files that were added during the execution of the loop in this code ?

I have to be able to read files that have been serialized in VB. 2 things, 1 they are serialized in Binary, and I tried to look up on how to serialize/deserialize in Binary, but didn't have much support...
Also in the VB code they talk about "TYPES" which seems to be to just be a class full of stuff...

View Replies View RelatedMy application depends on eight default user roles (or account types). They can be renamed or disabled, but should not be deleted. I want to protect them from deletion using their uuid value from the db. How can I pass their uuids into a single variable so I can use that single variable in my conditional statement? If I should use an array, any example of how I might do this?
View Replies View RelatedThis particular program is supposed to prompt the user to input either an uppercase or lowercase Y to process a phone number, they are then prompted to enter the character representation of a phone number (like CALL HOME would be 225-5466), this repeats until the user enters something other than the letter Y. All of the words entered are to be stored into a single array. The program is then to convert these words in the array to actual phone numbers. Here is what I have so far.
import java.util.*;
public class Program1 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String begin;
int phoneNumber = number.convertNum();
[Code] ....
I realize that the second method doesn't have anything to return yet, I just wanted to put that in there while I was doing things that I actually know how to do ha. The convertNum() method is supposed to be the method with which the array of characters is converted to phone numbers.
I'm still trying to think my way through this. I would think it'd be easier to store the inputs from the user as individual letters rather than words for the sake of converting to phone numbers.
Also, we are only supposed to recognize the first 7 letters of each word that is entered, like the CALL HOME example, there are 8 letters but it's still a seven digit phone number, so I'm not sure how that would work.
Also, when printing the phone numbers after they've been converted, we're supposed to print the hyphen after the third number, I have no clue how that would be done from an array.

I have got a pretty good framework working for my hangman game so far, however I am quite stumped on how to find multiple instances of the same letter in a single string. I am using indexOf to find the instance of a character in a string, but it only returns the first instance. So if the words(s) contain(s) multiple instances it doesn't register the rest.

I need to write out multiple BufferedImages to a single tiff file. Each image represents a seismic time slice which can be several megabytes in size. I have used the TIFFEncodeParam.setExtraImages method and saved all my BufferedImages to a vector but my since I create so many BIs I keep running out of memory. Is there a way to create a BI, write it out to a TIFF file, then discard the BI and create the next one?
