How to export Java JOGL GlueGen project in BlueJ?

I want to export my Java project to a standalone Jar or exe file. I use blueJ as an IDE and I use following libraries: GLOOP, JOGL and GlueGen (aswell as pi4j). Running the program in the IDE itself works flawlessly, however when I export the program as a .jar file and wrap it into an exe with Launch4j I get following error:
Catched IllegalArgumentException: No Jar name in <jar:file:/C:/Users/neche/Desktop/UfoSpiel.exe!/com/jogamp/common/os/Platform.class>, got <UfoSpiel.exe>, while TempJarCache.bootstrapNativeLib() of null (null + null)

I have googled a lot but never found someone who had the same problem or used the same OS or IDE.
It would be amazing if anyone of you could help.
Here is the main thread code:
import GLOOP.*;
public class UfoSzene
{
public static void main(String[] args)
{
GLKamera kamera;
GLLicht licht;
GLBoden weltall;
UfoSpiel ufoSpiel = new UfoSpiel();
Punkte punkteStand = new Punkte();
weltall = new GLBoden("Weltall.jpg");
kamera = new GLKamera(800,800);
kamera.setzePosition(2000,3001,20);
kamera.setzeBlickpunkt(2000,0,0);
licht = new GLLicht();
ufoSpiel.start();
punkteStand.start();
}
}
Thanks in advance!

Tess4J InvocationTargetException

I have a problem running the below java code outside of the eclipse compiler. Inside the compiler it works fine, but after exporting as a runnable jar I get an InvocationTargetException. I believe it is relevant to the dll files but after reading other solutions here and tryinging to implement them the problem remained unresolved. So my question is it possible to configure eclipse, through code or settings, to export the program correctly?

In case anyone has a similar issue what I did was copy the 3 .dll files into my System32 folder. I then got an issue with image.io, which the site had plenty of answers for. My personal solution was exporting the jar as my code and a separate folder for the libraries.

Error when trying to execute a command in java [duplicate]

This question already has answers here:
How to use "cd" command using Java runtime?
(8 answers)
Closed 9 years ago.
I am trying to run a java file using the terminal but from java. Meaning, I'll run the command using java.
I am trying to execute the command 'cd /Users/apple/Documents/Documents/workspace/UserTesting/src ' that redirects to the following directory and then execute the command 'ls' that lists all the files in the current directory
I am using this method to run the Java file 'NewFile.java'
try {
String line;
Process p = Runtime.getRuntime().exec( "cd /Users/apple/Documents/Documents/workspace/UserTesting/src" );
Process p2 = Runtime.getRuntime().exec( "ls" );
BufferedReader in = new BufferedReader(
new InputStreamReader(p2.getInputStream()) );
while ((line = in.readLine()) != null) {
System.out.println(line);
}
in.close();
}
catch (Exception e) {
// ...
}
The output
Directly using the terminal -> It gives 'NewFile.java'
Using this method using Java -> It always give 'bin' and 'src' for whatever command given to p2
Here are several trials

So, it seems the problem you're having is that you don't understand why you get different results when you invoke the program in different ways.
Here's what's going on: Runtime.geRuntime().exec() creates a new process, which is a child of the parent. Every process has its own working directory; when you fork a new process, it inherits the working directory of the parent. Invoking cd will then change the working directory of the current process (and this is a shell builtin, but ignore that for now and I'll get to it later).
So what you're doing is this:
Parent
-> create child 1 -> change working directory of child 1
-> create child 2 -> invoke "ls"
Note that child 2 will inherit the working directory of its parent. It won't know anything about the working directory of child 1. So depending on the working directory of the process that is invoking this method (in your case, either the terminal or...I don't know, your JDK install?) you will get different results.
If you want the same results every time, you could do something like this:
Process p = Runtime.getRuntime().exec( "ls /Users/apple/Documents/Documents/workspace/UserTesting/src" );
And if you want to be able to exec your program from anywhere, just use the full path:
Process p = Runtime.getRuntime().exec( "java /Users/apple/Documents/Documents/workspace/UserTesting/NewFile" );
(assuming, of course, that you have already used javac to build NewFile.class in that directory, and that you have the right permissions to execute it.)
Re: cd, as I mentioned before this is a command that's built into your shell. When you invoke the command using exec in this way, it is likely failing. You can check on that by reading standard error using the getErrorStream() method of Process.

writing a udf in pig kind of like tutorial

I am new to pig.. and am trying to write a udf function.
So basically here is the problem statement.
I have a dummy data like this..
user_id, movie_id, date_time_stamp
So what I am trying to do is this.
if the transaction is between
9 am and 11 am --> breakfast
and so on
So here is my pig script
REGISTER path/myudfs.jar
in = LOAD 'path/input' USING
PigStorage('\\u001') AS (user:long,movie:long, time:chararray);
result = foreach in GENERATE myudfs.time(time);
STORE result INTO 'path/output/time' using PigStorage(',');
Now myudf.jar java code is like this
public class time extends EvalFunc<String>{
public String exec(Tuple input) throws IOException {
if ((input == null) || (input.size() == 0))
return null;
try{
String time = (String) input.get(0) ;
DateFormat df = new SimpleDateFormat("hh:mm:ss.000");
Date date = df.parse(time);
String timeOfDay = getTimeOfDay(date);
return timeOfDay;
} catch (ParseException e) {
//how will I handle when df.parse(time) fails and throws ParseException?
//maybe:
return null;
}
}
So it takes in the tuple and returns a string... (I am new to java also..)
After this i try to run this script as
pig -f time.pig
It returns an error

Some one posted on pig mailing list is that my PIG_CLASSPATH is not set and that i should point it to /path/hadoop/conf
I did that.. so now $echo PIG_CLASSPATH --> /path/hadoop/conf
But i get the same error
Please advise.
Thanks

is this like a java issue?

To find the jar version, open the jar using winzip (or similar) and look for manifest.mf. There should be a line in there that says 'Created-By' and this will give the version of java that was used to build the jar.
This needs to be older or equal to the version of java you are using to build your app. If you are doing this at the command line type:
java -version
or in eclipse go to
project(menu) > properties (menu item) > java build path (in list) > libraries (tab)
and take a look at the version that you are using for the JDK/JRE (you may be able to tell this from the directory, if not then go to that directory and do java -version).
Chances are you'll need to update the version of java you have in eclipse.

How to Use External Class Files in an Eclipse Project

My lecturer didn't provide us with the .java files for a tutorial. My question is, how would i use his class files in my eclipse project, and defeat the following error?
Error:
Exception in thread "main" java.lang.NoClassDefFoundError: lec/utils/InputReader
at randomIt.main(randomIt.java:17)
Caused by: java.lang.ClassNotFoundException: lec.utils.InputReader

Here is my code:
import java.util.Random;
import lec/utils.InputReader;
public class randomIt {
public static void main(String[] args) {
Random generator = new Random();
InputReader myReader = new InputReader();
//Pick a number randomly between 1 and 10!
int number = generator.nextInt(10)+1;
//Ask user to guess...!
System.out.println("Take a guess (1 to 10)");
if (number == myReader.readInt()){
System.out.println("You win");
}
else {
System.out.println("It was " + number + ", tough Luck");
}
}
And here is my Folder Structure:
Random /
*/ bin
* / lec / utils /InputReader
* / src / randomIt.java
Note: his class file is "InputReader.class"

I've had a play with Eclipse to work this one out. Give the following a go:
Create the following directory structure (your desktop will do) classes/lec/utils
Place the InputReader class file in the utils directory.
Remove any references you have to InputReader you currently have in your build path.
Using (right click on project) Properties->Java Build Path->Libraries select the 'Add external class folder' and select the 'classes' folder you created on your desktop and click OK.
Now in the 'Referenced Libraries' in the project folder you should have one called 'classes' and a package path under that called 'lec.utils' which contains the InputReader class.
You can use that class using 'import lec.utils.InputReader' in you own class.
Hope that Helps.

In the project configuration menu, there is a "Build Path->Configure Build Path" menu item. Within that, there is an option to add an "external class folder". Put all the provided class files in a folder, and add that folder to the build path.

You should make the following changes
Modify your randomIt class to have following include line (no lecs/ )
import utils.InputReader
Modify the filename as rnadmIt.java (and not randomit.java) . The class name and fie name has to be exactly same. Also per Sun convention the class should start with a capital letter
$ cd Random
$ javac -classpath ./lec src/randomIt.java
