I'm trying to export a runnable jar file that requires lwjgl. Everything works in eclipse as I'm using
-Djava.library.path=nativewindows
as a VM Argument for the jinput .dll files.
After exporting & launching the jar it doesn't work of course! I get this error:
java.lang.UnsatisfiedLinkError: no junput-dx8 in java.library.path
I'm not sure how to make it work outside of eclipse....
My app uses docx4J, XStream, and also uses an image on the start page. I placed all of this external libraries in Java Buid Path and in Eclipse it all works well but when I export all data to runnable jar file it doesn't work.

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'm looking for a working example of shadow mapping with java code using shaders. There are so many c++ or c tutorials out there but i haven't managed to rewrite them since I'm too bad in c/c++. I've been trying to implement this a long time but can't get the hang of it. Any example out there? Preferably as sstripped down as possible except for the shadow mapping.
View Replies View RelatedI want to render a specific region of an image in LWJGL,
View Replies View RelatedI've recently started programming with lwjgl, playing around with some 3D graphics. I've built a house and now I'm trying to render a view looking straight onto the center of the roof, but with current configuration it's slightly off.
As you can see in the image the edges on the roof aren't perfetly straight which would be the case if I was looking straight to the center from a point on the roof normal vector. I'm using gluLookAt to get the view, using the following code:
gluLookAt(house.getRoofCenter().x + house.getRoofNormal().x * 0.25f,
house.getRoofCenter().y + house.getRoofNormal().y * 0.25f,
house.getRoofCenter().z + house.getRoofNormal().z * 0.25f,
house.getRoofCenter().x, house.getRoofCenter().y, house.getRoofCenter().z, 0.0f, 1.0f, 0.0f);
And for the normals:
Vector3f.sub(p2, p1, a);
Vector3f.sub(p3, p1, B)/>/>/>;
Vector3f.cross(a, b, c);
roofNormal = new Vector3f(-c.x, -c.y, -c.z);
and center:
roofCenter = new Vector3f((p3.x + p1.x) / 2, (p3.y + p1.y) / 2, (p3.z + p1.z) / 2);
My question is: Is this due to errors in the rendering methods or is my math off?
Im trying to do this
if( 2/2 ) {
system.out.println( "number is not event" );
} else {
system.out.println( "number is event" );
}
However if statement requires a return of type boolean. So im forced to this instead
if( (2/2) != 0 ) {
system.out.println( "number is not event" );
} else {
system.out.println( "number is event" );
}
Is there a way to achieve the former method, without typecasting, if you had to typecast how do you do it?
I am doing a homework assignment and I am clueless as to what I did wrong or supposed to do in terms of placement of coding. If someone could dumb down their response and tell me what I did wrong
This is what I supposed to do:
1.) Type the following shell for the class:
public class ParadiseInfo
{
}
2.) Between curly braces of the class, indent a few spaces and create the shell for the main() method:
public static void main(String[] args)
{
}
3.) Between the braces of the main()Method, insert a call to the displayInfo() method:
displayInfo();
4.) Place the displayInfo() method outside of the main() method, just before the closing curly brace for the ParadiseInfo class:
public static void displayInfo()
{
system.out.println ("Paradise Day Spa wants to pamper you.");
system.out.println ("We will make you look good.");
}
This is what I attempted to do: I know it is wrong I am just clueless on where to put the code and why
public class ParadiseInfo
{
displayInfo();
public static void main(String[] args)
{
public static void displayInfo();
}
system.out.println("Paradise Day Spa wants to pamper you.");
system.out.println("We will make you look good.");
}
--- Update ---
I have also tried this:
public class ParadiseInfo
{
displayInfo();
public static void main(String[] args)
{
}
public static void displayInfo();
{
[Code]...
The very last attempt I only ended up with one error which is:

Java is very new to me and I have no clue on what I am doing wrong.
I am currently working on a Minecraft clone (called "Build"), and I'm trying draw just ONE simple dirt block, but it will only draw a square!
Here is the main class:

And the Block class ( the one that all Block Types are based off of):
package game;

And that is the code, I'll make updates as needed.
I want to make several classes which extend different objects and add additional functions to simplify them and make their purpose in my projects more narrow and make their instances easier to use. So an example, Image class which extends BufferedImage and the constructor in Image class directly loads the file without having to create it first and then have to use Try Catch and all that additional code. Now, here is where my question comes in. Can I make an class, an abstract class or something which can be IMPLEMENTED into these several classes such as the Image class, and in doing so those several classes will have to have (like unimplemented methods) a HashMap<String key, ChildClass instance_as_value>, child class being the Image class as an example.
So I would have something like public class Image extends BufferedImage implements Library, and this class, because it implements Library will have a HashMap<String key, Image value> in it or it's parent class.

I have a JFrame with a button called "Start". The code behind the "Start" button triggers a function (startwork() ) that traverses through log files and then inserts rows into my JTable. If I call the startwork() function from the Start button action performed event, then when it inserts the rows to the JTable it is not immediately shown...
The code has to finish before the JTable is refreshed. However, if I run the startwork() function as soon as the JFrame is displayed (from the main() function) then I can see the Jtable being populated dynamically as it is inserting the rows.
How to allow the user to click on the START button and yet behave correctly to where the JTable is updated properly so that I can see the rows being inserted as it progresses.
I have a superclass used for all the other entity

@Temporal(TemporalType.TIMESTAMP)

When i try to read some data with a JPA controller, this error is raised:
Persistent class "com.bss.libbssabstract.database.entity.BssStandardEntityLaravel" has no table in the database, but the operation requires it. Please check the specification of the MetaData for this class.

It requires BssStandardEntityLaravel table like a normal entity. I used the same entity package in other applications and it works perfectly. Why this error is raised?
I use jpa2.1.0 and datanucleus to enhance classes

I'm making an import/export of xml - I have the import of xml sorted I'm just trying to finish off the export. My export class is called XmlWriter.java. Inside the class I have an updateFile method to update an xml file as such:
public void updateFile(Environment environment,Document doc)
{
// code
}
I then in my main method have
public static void main(String argv[]){
//declare new object of class
XmlWriter xmlWriter = new XmlWriter();
//test testUpdate method
// xmlWriter.testUpdate();
Environment environment = ;

I don't know what to make my variables equal to - eclipse keeps trying to use null but obviously that won't work. The Environment is another class that just contains getters and setters for the 3 different databases (that are in the xml file) and the getter/setter for the environment ID (also in xml file).

for (int i=0;i<ColumnCount;i++) {
System.out.println("Inside for");
Label label=new Label(i,0,rsmd.getColumnName(i+1),cellFormat);
sheet.addCell(label);
WritableCell cell = sheet.getWritableCell(i+1, 0);
System.out.println("Column " + rsmd.getColumnName(i+1)+ " inserted");
