As far as the folder structure is concerned, it has a project that creates an ear file, and has one for project for web and another project for EJBs. there is one more project that holds some property file.
I am trying to mavenize this this application, so that I am able to create an ear of application containing the war of web project, jars of property project and ejb project and I am badly stuck.

I have completed an assignment for my university in which I had to make a Java NetBeans project. My project is now completed but now I have to make a setup of my NetBeans project and give the university the setup file, only.
My question is, the software I made has a database attached to it, meaning the purpose of the software is to be used with the database. Values must be saved in the database, deleted from the database etc.. I have used MySQL database connections with the JDBC driver
I have used exe4j to make the .exe file and Setup Factory to make the exe file and setup file respectively. Once I make the setup and run the setup, the application works, ON MY COMPUTER. The computer which made the software. But once I take it to a computer in which MySQL was not installed, the setup installed, but the software did not work.

DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("config");

This code is working properly but i have use path like this
File configFile= new File("srcconfig.xml");
Instead of system directory path i have to use path inside of project but i am getting an error-cannot find the specified file...

I tried many times to return a string from java project to an android project But it keeps sending incorrect values as in 2 as it should be 1 here is an example.
Java Project:
boolean somethingboolean = false;
if(something.equals("1")){
somethingboolean = true;
}
public static String getString(){
if(somethingboolean == true){
[Code]...
Android project:
System.out.println(JavaProject.getString())
and in the android project it prints "FALSE"
So what should i do?

When reading RT-38432 I see that Danno mentions the possibility to use:
com.sun.javafx.application.LauncherImpl.launchApplication(YourMainClass.class, Preloader.class, args);
I've never used the javafx-packager and have always used the above instead. However, I assumed I was missing out on some optimization related to example 9-5 and example 9-6 of Deploying JavaFX Applications: Preloaders | JavaFX 2 Tutorials and Documentation. I always assumed the supported packaging:
1) Loads only the JARs / resources needed to launch the Preloader.
2) Launches the Preloader.
3) Loads all other application JARs / resources.
4) Launches the application.
Now I'm thinking that's only the case for Web Start deployments. For standalone deployments is it the same as a normal Java application where all of the application JARs are included as part of the classpath?

I done a small application with Javafx that start an Embedded Jetty. All works fine in Windows also with native package. Instead in Mac it works only before native packaging. Seems that the problem is how relative path are considered.
The tree of the content is this:
myfile.jar
webapp (folder)
libs (folder)
Look at this code:
String webAppDir = "webapp";
File f = new File(webAppDir);
log.debug("Path webapp folder: " + f.getAbsolutePath());
if (!f.exists())
throw new Exception("The folder " + f.getAbsolutePath() + " doesn't exist");
[Code] ....
The problem is that before the packaging in Mac the relative path is that where the main .jar is located an so the code works because the webapp folder is found. Instead after the bundle the path became /Users/MyUser/webapp and of course the folder is not found because it is bundled inside the file.app near the libs folder.

After some attempts I seen that my preloader is not shown using native package (Windows and Mac).
Running the jar that is run from the file.exe instead I can see the splash screen.
This is the relevant part of my build.xml
<fx:application id="fxApplication" name="app" version="3.0" mainClass="it.app.Main" preloaderclass="it.app.preloader.SplashScreenUi" toolkit="fx" />
As said, running the jar file instead of exe file the splash screen is displayed.
I printed some logs into splash screen class: when I run the app from the jar this logs are printed, instead when I run the app from .exe file these logs are not present.

I need to build an application that can preform measurements. So I have a measuring device that can be connected through USB (with a rs232 converter aka VCP).The manufacturer provided me with two libraries:
C++ : a library (.lib) file and a header (.h) file
VB6 : a DLL (.dll) file and a list (.txt) with all the available functions
And also some demo code. Can't get the C++ code running with my Borland C++ 5.5 compiler but the VB6 code is working.What can I use to integrate into my java code.

I've been trying this for hours but it's not working. I'm trying to add the sea glass look and feel library to my project but I still get the error:
Exception in thread "main" java.lang.NoClassDefFoundError: List (wrong name: list)
What should I do? I've added the library to "project settings >Required Libraries" and did not forget to check the box. I've also imported the L&F so it can't be that.

I'm researching the viability of a project. One of the requirements is that a "play slip" will be used to read input. I've searched for open source Java libraries that utilize OMR's (optical mark reader) but to no avail. I have located a C library that fulfills the task- is there a way in Java to access/use non-native language libraries?

I am responsible for an application which the developer did not build with ANT and also, he had the libraries sitting on his local machine.
Do you have any recommendations on what I should do with these libraries, knowing they were parcelled out and sitting on his local machine instead of in the project itself (Eclipse IDE workspace)?
I am building a script in ANT but don't really know what to do with his libraries. I did get a bunch of compilation errors earlier when I did not have the libraries, but now that I have them, I don't really know where to put them.

I have an XML doc that looks like this:
Java Code:
<?xml version="1.0" encoding="UTF-8"?>
<model>
<id>_1</id>
<nodes>
<id>_2</id>
<stencil>TASK</stencil>
</nodes>
<nodes>
<id>_3</id>
<stencil>TASK</stencil>
</nodes>
</model> mh_sh_highlight_all('java');
I have to create another xml doc with the properties of nodes from the first doc. For the new doc I have to create a parent node called "definitions". Instead of the "model" node in the first doc I have to create a "process" node in the new doc that has an attribute "id" which value is the same as the content of the "id" child node of model. For each "nodes" node in the first doc if their "stencil" child node content equals "TASK" I create a "task" node in the new xml doc.
Java Code: <?xml version="1.0" encoding="UTF-8"?>
<definitions>
<process id="_1">
<task id="_2">
</task>
<task id="_3">
</task>
</process>
</definitions> mh_sh_highlight_all('java');
[code]....
I just wanted to know if this is the correct way to define the respective classes.any way to create and fill the nodes for the new doc using this classes? I am used with DOM parser and I know how to create nodes and fill attribute values, but I have always done this job in a single class, not using different classes for the elements.

I'm trying to make my first servlet, however since I have only installed the Java SE, the javac compiler is complaining about missing packages (javax.servlet.http...)
I've realized now that I need javax.servlet jar or class files from Java EE, but after downloading java_ee_sdk-7u1.zip from Oracle here I'm not seeing any .sh or java_ee_sdk-7-jdk7-macosx-x64.sh installer (which I saw mentioned elsewhere). The oracle page only instructs to unzip the downloaded file, and searching for javax.servlet only reveals a few files which I'm not sure what to do with:
javax.servlet-api.jar,
javax.servlet.jsp.jar,
javax.servlet.jsp-api.jar,
javax.servlet.jsp.jstl.jar,
javax.servlet.jsp.jstl-api.jar,
javax.servlet.ServletContainerInitializer,
How do I go about installing the Java EE libraries I need? I am on a mac, and I'd like to do this without IDE, using the command prompt if necessary.

I am not necessarily 'new' to java, however I have always used NetBeans so I am not entirely sure how to do what I need with the terminal commands. I am trying to execute a java jar file(which works perfectly on windows) on the Raspberri Pi, essentially debian linux.
As I mentioned previously, I have a java jar file which I can execute on windows, but it depends on three other libraries, namely RXTX, MySQL, and JSON. I am not positive how to compile this into a jar, or execute it in debian.
This was how I attempted to load two of those libraries, however the last line is the error I received.
Direct copy from the terminal:
pi@raspberrypi ~/Desktop $ java -Djava.library.path=/usr/lib/jni -cp /usr/share/java/RXTXcomm.jar:/usr/share/java/mysql-connector-java-5.1.10.jar:. Automation_System.core.HAS
Error: Could not find or load main class Automation_System.core.HAS
Specifically, the problem seems to be that I cannot use the -cp flag to indicate classpaths, and the -jar flag indicating I am executing a jar in the same command. I am not sure how to point the compiler to my main class HAS in the core package of the jar, and also to the libraries referenced.

I wrote my own class to represent univariate polynomials and it works fine, but I was quite sure I was reinventing the wheel, and should obviously like to extend my program's functionality using other kinds of mathematical object.
I've been looking and there are of course open source libraries available which contain everything I'd want to do myself, and more, and probably better, saving me a lot of work.
However the usefulness of this kind of library extends far beyond simple practice and would be invaluable in developing more complex applications.
If I were to plan to write an application that I would at some point in the future like to compile into an executable and sell, would I need to take care about any open source libraries used that the compiler relies on? If so, would it be possible at that stage to use just the API and write my own classes replicating the functionality to avoid breaking license agreements?
The library I'm looking at right now is distributed under the Apache license.

My task is to implement a B-Tree data structure in Java using no libraries.
My current problem is inserting when the root is full, thus the middle key goes to root.keys[0] and then it get the left and right side which are new Nodes separating and inserting their keys. My problem is that for some reason there is a random second number when in the root and secondly my boolean leaf is always false meaning it never detects that the Tree is deeper than root.
The coding makes sense to me and I have tried printing everywhere but still can't seem to find the problem.
public class BTree {
/*
1. You may not modify the public interface of this class. You may however add any additional methods and/or field which you may require to aid you in the completion of this assignment.
2. You will have to design and implement a Node class. The BTree should house Integer objects.
3. You will notice that there are some overloaded methods, some of which work for Integer objects and some with primitive type int. You have to find a way to implement the methods to work with both types.
*/
class BTreeNode {
boolean leaf = true;
int numKeys = 1;
int mOrder;
Integer keys[];
[Code] ....
