How To Write ID3 Tags Using MP3agic Library
Apr 22, 2014
I am trying to write the id3 tags using mp3agic library. The problem is it does not update the id3 tags for the mp3 files which already contains id3 tags but it only updates the file that have id3 tags which are empty.
When i look at the newly created files, they contains the older tags. Then i wrote a script to access id3 tags through mp3agic
id3v1Tag.getArtist()
then it was showing updated tags.
Why it is showing updated tags even if they are not really updated in folder where i visits ?

Is there anything wrong with writing JSP tags in psuedo-HTML? I've been writing tags in XHTML, but it would seem that XHTML could not be compliant with both an XHTML standard and the HTML5 standard.

My jsp page needs to have a dropdown box. on selecting one/more than one values from this list, the same values get populated in another one.. we have a delete button too , it allows to populate the second box again.
The thing is i am to avoid scripts and use custom tags as much as i can...

I know jspf is a jsp fragment, but can't a tag also serve as a jsp fragment?

I have some XML tags in jsp like.
<esi:assign name="searchfor">'''someval like < or >'''</esi:assign> . Now on the basic of request param i want these tags should render with value < or > on the basis of what is inside tags. I applied the below code but didn't work. Any Idea.
<c:if test="${testval}" >
<jsp:text><![CDATA[<xmp>]]></jsp:text>
</c:if>
<esi:assign name="searchfor">'''>'''</esi:assign>
<c:if test="${testval}" >
<jsp:text><![CDATA[</xmp>]]></jsp:text>
</c:if>

how to use SAX Parsers. I've looked at a few tutorials and have the generals down. I have an xml file that the parser is trying to read. As you see below, at the start of each element, I add the tag to an arrayList of the tags. I create a stringBuilder to capture the text between tags, this won't work unless it occurs at the end of an element. If it occurs at the start, it never gets the chance to read the text.
This is where the problem occurs. For nested tags, like project, it reads the last nested tags' text and stores it in the text arrayList. Project may be the first indexed tag in the tags arrayList, but project's text is the fourth indexed element of the text arrayList. So when my test print the arrayLists by index, it gets thrown off. I want over tags to store a blank space in the text array, and at the same index of the tag its associated with. How would I do this?
I've tried overwriting the text arrayList, but couldn't get my logic thought out for how to determine if a tag was nested. I always ended up overwriting blank space to each element.

I am familiar with php, but I don't know Java. We need a program, that will be able to scrape large amount of title tags from large sites, fast. I've been trying Seo Spider by Screaming Frog, and Xenu's Link Sleuth, but these programs are not good enough. They hang up, they save all the data in RAM, I think, and after a relatively short period of scraping, they stop working, become unresponsive, and so on.
Somebody recommended me getting a custom made program in Java, which would be able to scrape title tags only, from large sites (I am talking 25 - 50 million pages or more). I was told that it would not have a graphic interface, or anything like that. Nothing like this is needed too, we just need to have title tags.

In order to create an xhtml view:
1. All jsf tags like datatable, form, etc.. will generate UIComponents in server side, right?
2. All non JSF tags will not generate UIComponents in server side, right?
3. If you want something in a view that will be the same across users and requests, I mean, It will not change like a label tag, it doesn't make any sense to create it with a JSF tag in order to save memory in server side, right?

I know that the simple deployment using only applet tags inside HTML causes severe security restriction for the applet on the client side. but can this simple HTML file contains .jar files inside the applet tags instead of .class files.

I see you can import in 2 ways:
import java.util.*;
or
import java.util.Scanner/Random/etc;
if I used the first one it imports all the librarys within that (directory?). If so would that add to a bigger file size?

My perfect idea is to have a Hashmap that would increase size each Key & value added, it's almost like a self-increasing array. I mean I could just create a very large Hashmap for me to add objects to anytime I want with a key to be able to find the object. Is this the most efficient way, because I'm trying to make my Object Library compatible with any amount of Objects, however, I know there's a limit to how many values you can have in an array, but it's larger than I'll ever need.
Let's say I'm making a number storage program, and I may need from 3 to 8 numbers to be stored with a key to find them easily using a Hashmap, rarely I may need below 3 or above 8. So is it efficient for me to create a Hashmap that has 10 placeholders? Or can I make this more efficient. Note, my Library is static.

I'm just a java beginner. I've spent a lot of time installing and configuring software. I'm using Netbeans 7.3 on Windows 7, 64 bit. Recently, I downloaded opencsv from sourceforge.
With no previous experience adding libraries, I read a blog post on adding the library. I think that I then:
Start a new project.
Right click on libraries
Add jar/folder
Gave the temporary path to the .jar file
After, I read the blog post again, and realized I'd missed it. This time I did:
Right click library, Add library, Create library
However, I kept getting a message that the same library already existed. If I do the first process above, I will find the same library.
However, I see no way in Netbeans to remove it. I've deleted the test projects. And started a new one. But the library now exists for all projects it seems.
I've grepped all the files under the Netbean directory, searching for "opencsv", but found nothing. The only things in the Windows registry were locations of files.
How can I delete this library permanently from Netbeans? Short of, uninstall, then reinstall? Is there a way to list all the libraries that Netbeans has?

So I'd like to make like a library of tiles, and it isn't too big, which I could just call using a method, and I would specificy what information I need to get, and it would return that information.
For example, a small section of the tiles library is grass_tile, I call this library and specify what I need, and in this case let's say I need the width, or can the character enter it from north? or can the character just stand on it? So it's like a library or array, with sections of it being named by tiles, and by mentioning these tiles I can information about them.
gTile("grass","walkon") will return true, first because I specifiy grass, and yes the character can walk on grass, so it returns a boolean value of true.
gTile("stone","width") will return 16, first because I specify stone, and the stone's png image size is 16.
What I'm asking is not for how to work out if the character can walk on the tile, or read the width of a tile, but can I create like a library from which I can obtain information by giving the name of the tile, and then telling it what info I need.
If up key pressed && gTile((yTILE + 1).name(),"walkon") == true then moveChar("up")

i have been given a homework assignment where I have to get rid of a stack object I wrote for a program and replace it with the Stack<E> library java offers ie:
public class Stack<E> extends Vector<E> {
public Stack(); // constructor
public Boolean empty();
public E peek();
public E pop();
public E push(E item);
}
my question is do i have to actually write all these methods? Or can i just construct a stack and use the methods?

On the first run, everything loads perfectly. The second run, I get the "Could not locate OpenAL library." error. I have the most updated version of slick/lwjgl. I have no clue why this is happening.I should also say, this error only happens if I get a message in the console saying "1 device not closed.." message for OpenAL. Here's the error message:
