libgdx not initialized yet

I have been coding my libgdx application (for desktop only) for a while and after deciding to cleanup the code part by part iv'e gotten into a problem i cant seem to solve myself..
exception:
Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: java.lang.UnsatisfiedLinkError: com.badlogic.gdx.physics.box2d.PolygonShape.newPolygonShape()J

after googling for a while i figured my error is as mentioned in this thread
as in
Another problem might be that you instantiate a SpriteBatch (or something else which internally uses a SpriteBatch) too early (looked a bit like this in the stacktrace).
but as the answer mentions
Instead, create such things in the create/show methods of your game.
I cant seem to understand when libgdx is initialized and ready for use, and where to place my GameUtils.init() method to assure libgdx is initialized
My code is as follows: (i have taken out e-relevant methods)

Help is much appriciated! :D

As I've already wrote in the other linked answer, make sure that your project is correctly set up. Box2D is an extension and needs its own native libraries to be able to run.
It seems that it's a specific problem with the Box2D natives which are not loaded yet. They are not loaded automatically when LibGDX is initializing, but you have to trigger that yourself (see wiki).
The code you've posted looks correct, but before you can use anything Box2D related, you have to call Box2D.init(). Alternatively, creating a World object does the same, but isn't the nicest way to do it.

passing argument to WordCram code

I have the following question: I am trying to execute the usConstitution wordcram example (code follows) and if provided as is the code executes in eclipse, the applet starts and the word cloud is created. (code follows)
import processing.core.*;
//import processing.xml.*;
import wordcram.*;
import wordcram.text.*;
import java.applet.*;
import java.awt.Dimension;
import java.awt.Frame;
import java.awt.event.MouseEvent;
import java.awt.event.KeyEvent;
import java.awt.event.FocusEvent;
import java.awt.Image;
import java.io.*;
import java.net.*;
import java.text.*;
import java.util.*;
import java.util.zip.*;
import java.util.regex.*;
public class usConstitution extends PApplet {
/*
US Constitution text from http://www.usconstitution.net/const.txt
Liberation Serif font from RedHat: https://www.redhat.com/promo/fonts/
*/
WordCram wordCram;
public void setup() {
size(800, 600);
background(255);
colorMode(HSB);
initWordCram();
}
public void initWordCram() {
wordCram = new WordCram(this)
.fromTextFile("http://www.usconstitution.net/const.txt")
.withFont(createFont("https://www.redhat.com/promo/fonts/", 1))
.sizedByWeight(10, 90)
.withColors(color(0, 250, 200), color(30), color(170, 230, 200));
}
public void draw() {
if (wordCram.hasMore()) {
wordCram.drawNext();
}
}
public void mouseClicked() {
background(255);
initWordCram();
}
static public void main(String args[]) {
PApplet.main(new String[] { "--bgcolor=#ECE9D8", "usConstitution" });
}
}
My problem is the following:
I want to pass through main (which is the only static class) an argument so as to call the usConstitution.class from another class providing whichever valid filename I want in order to produce its word cloud. So how do I do that? I tried calling usConstitution.main providing some args but when I try to simply print the string I just passed to main (just to check if it is passed) I get nothing on the screen. So the question is How can I pass an argument to this code to customize .fromTextFile inside initWordCram ?
Thank you a lot!

You can’t pass command-line args directly to WordCram, because it has no executable.
But you can make an executable wrapper (base it on the IDE examples that come with WordCram), and it can read command-line args & pass them to WordCram as needed.
FYI, it’ll still pop up an Applet somewhere – AFAIK, you can’t really run Processing “headless.” But that’s usually only a concern if you’re trying to run on a server.

Passing an Enum to a method as a parameter in Java?

I am trying to call a docx4j method "setAlgn" in the interface CTTextParagraphProperties, which, per the docx4j jar I am using and the compiler takes an Enum type as a parameter. I am passing the actual argument STTextAlignType.CTR which I believe should resolve to the value 'ctr' (citation: http://grepcode.com/file/repo1.maven.org/maven2/org.docx4j/docx4j/3.0.1/org/docx4j/dml/STTextAlignType.java?av=f, I am running this same code).
Here is my code:
import java.lang.Enum;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;

public static XSSFTextBox createTextBox(XSSFSheet sh, String message, int row1, int col1, int row2, int col2, boolean is_bold, boolean is_italics, boolean is_underline, boolean centered, int fontSize){
//Various apache-poi stuff
XSSFWorkbook wb = sh.getWorkbook();
XSSFDrawing drawing = sh.createDrawingPatriarch();
XSSFClientAnchor clientanchor = new XSSFClientAnchor(0,0,0,0,(short)col1,row1,(short)col2,row2);
XSSFChildAnchor childanchor = new XSSFChildAnchor(0,0,0,0);
XSSFShapeGroup group = drawing.createGroup(clientanchor);
XSSFTextBox textbox = group.createTextbox(childanchor);
XSSFRichTextString richMessage = new XSSFRichTextString(message);
XSSFFont textFont = wb.createFont();
textFont.setFontHeightInPoints((short)fontSize);
textFont.setFontName("Verdana");
if(is_bold){
textFont.setBoldweight(XSSFFont.BOLDWEIGHT_BOLD);
}
textFont.setItalic(is_italics);
if(is_underline){
textFont.setUnderline(XSSFFont.U_SINGLE);
}
if(centered){
//Here is the code in question.
textbox.getCTShape().getTxBody().getPArray(0).getPPr().setAlgn(STTextAlignType.CTR);
}
richMessage.applyFont(textFont);
textbox.setText(richMessage);
return textbox;
}
My compiler returns the following error message:
com\tem\POIStuff.java:1105: error: method setAlgn in interface CTTextParagraphProperties cannot be applied to given types;
textbox.getCTShape().getTxBody().getPArray(0).getPPr().setAlgn(STTextAlignType.CTR);
Ultimately, my question is how can I get the "setAlgn" method to accept 'STTextAlignType.CTR' as an Enum and not as object type 'STTextAlignType'? Thank you in advance very much for your help!

The problem is actually on the first line of your code snippet! Your issue is with
import java.lang.Enum;
CTTextParagraphProperties.setAlgn does take a class of type Enum, but it's not that kind of Enum. It has to be a org.openxmlformats.schemas.drawingml.x2006.main.STTextAlignType.Enum
I'd suggest you switch your imports to be:
import org.openxmlformats.schemas.drawingml.x2006.main.STTextAlignType;
import org.openxmlformats.schemas.drawingml.x2006.main.STTextAlignType.Enum;
You can then set the alignment with things like STTextAlignType.L and it'll work fine

Error when using ProtocolLibrary PacketAdapter()

I am making a Craftbukkit plugin that has a message in the player count list, Like HIVE-MC or Omega Realm. I am coding in Ecplise and using ProtocolLib v3.2.0 and Craftbukkit 1.7.2 R0.3. I am new to java and don't understand it much. I do know that everything is imported.
So far, here are the imported methods, code, and the error
Methods:
import java.io.File;
import java.io.IOException;

new File(getDataFolder(),"RESET.FILE").createNewFile();

new PacketAdapter(
this,ListenerPriority.NORMAL,
Arrays.asList(new PacketType[] {PacketType.Status.Server.OUT_SERVER_INFO}),
new ListenerOptions[] { ListenerOptions.ASYNC })); {
}
}
Error:
Cannot instantiate the type PacketAdapter

As you will see in the Javadocs for PacketAdapeter, it is declared as:
public abstract class PacketAdapter implements PacketListener
abstract means the class is not a full class, and must be implemented as a full class or anonymous class, it cannot be instantiated. You need to find a subclass of PacketAdapter, or make one yourself.
For more information, see the Java Tutorial for Abstract Methods and Classes.

List items = new ArrayList() : it does not work

Is all in the title,
I do not understand the problem this time is a bit different, I used the same Object(List) for two different programs and it does not work in the second time, see :
private void jMenuItem23ActionPerformed(java.awt.event.ActionEvent evt) {
init_creer_client();
List items = new ArrayList();
items.add("mawren");
items.add("blabla");
items.add("Bonjour");
CL.show(cartes,"creer_client");
}
screenshot about the error :
by cons here its work smoothly :
import java.awt.Dimension;
import java.awt.HeadlessException;
import java.util.ArrayList;
import java.util.List;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import org.jdesktop.swingx.autocomplete.AutoCompleteDecorator;
public class Test_swingx extends JFrame {
public Test_swingx(String title) throws HeadlessException {
this.setTitle(title);
JPanel pan=new JPanel();
JTextField jtf=new JTextField();
jtf.setColumns(20);
List items = new ArrayList();
items.add("hello");
items.add("marwen");
items.add("allooo");
AutoCompleteDecorator.decorate(jtf, items,false);
pan.add(jtf);
this.setContentPane(pan);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
this.setBounds(280, 150, 500, 200);
}
public static void main(String[] args) {
Test_swingx tsx=new Test_swingx("helloo swingx");
}
}
can anyone explain to me ?

You have a java.awt.List import should be java.util.List

It's because the List on the left-hand side is a java.awt.List instead of a java.util.List.
Try changing the line to:
java.util.List items = new ArrayList();
This is probably happening because you're importing java.awt.* and java.util.List. If you can change how you import these classes, you can avoid namespacing the type inline.

Nope, compiles fine:
package cruft;
import java.util.ArrayList;
import java.util.List;
/**
* ListExample description here
* #author Michael
* #link
* #since 2/11/12 7:27 PM
*/
public class ListExample {
public static void main(String[] args) {
List items = new ArrayList();
for (String arg : args) {
items.add(arg);
}
System.out.println(items);
}
}
Runs fine:
"C:\Program Files\Java\jdk1.7.0_02\bin\java" -Didea.launcher.port=7536 "-Didea.launcher.bin.path=C:\Program Files (x86)\JetBrains\IntelliJ IDEA 111.255\bin" -Dfile.encoding=UTF-8 -classpath . com.intellij.rt.execution.application.AppMain cruft.ListExample foo bar baz bat
[foo, bar, baz, bat]
Process finished with exit code 0

Sanity check: Have you imported both import java.util.List and import java.util.ArrayList?

Check your imports, because java.awt.List is not the same as java.util.List.

I think the confusion comes from having two List types in different packages, as the error message says. You don't give all the code that generates the error, but I think a reasonable start to a fix would be to change the highlighted line to:
java.util.List items = new ArrayList();
and make sure you have imported java.util.*
