EJB / EE :: Classpath Requirements For Facelets And CDI On Glassfish
Oct 29, 2014I don't understand the classpath requirements for facelets and CDI on glassfish. I'm using Netbeans, and have the following:
thufir@dur:~/NetBeansProjects/EntAppWeb$ jar -tf dist/EntAppWeb.ear
META-INF/
META-INF/MANIFEST.MF
lib/
EntAppWeb-ejb.jar
EntAppWeb-war.war
lib/javaee-api-7.0.jar
thufir@dur:~/NetBeansProjects/EntAppWeb$
when I look at javaee-api it has javax.enterprise.context.ApplicationScoped and javax.inject.Named which are the particular imports being used in the bean. The facelets part is working, the template navigates correctly. It deploys to Glassfish and runs, except...there's no output from the @Named bean:
package dur.beans;
import javax.enterprise.context.ApplicationScoped;
import javax.inject.Named;
@Named("nextClient")
@ApplicationScoped
public class NextClient implements NextClientLocal {
[code]...
Now it's working. I can't figure what I did for the life of me...that's the desired output, each time the page is accessed the counter increments.Now it works. Is this on the right track? Way off base? I have an entity class from a database which I'd like to link up to this, and output the class.I can inject the entity into NextClient? I'm trying to do the "R" for Read in a CRUD application with CDI and facelets (using templates).
I've found much reference material on EJB, but it seems a mishmash. I just want to use CDI. What am I doing right/wrong, or, besides the PDF from Oracle on Java EE 7, what are good CDI reference material's?

The System Cannot Find The Path Specified
Feb 25, 2015I have the Java Development Kit downloaded in my C file and my book tells me to compile the program I need to open command windowand change the directory where the program is stored. I tried the command cd to change directory and received this message "The system cannot find the path specified."
I checked the Environment Variables on Windows 7 and the Path says: C:Program Files (x86)Javajre1.8.0_31in
This is after many tries and i still can't change directory and i keep getting the same message.
Stock System In Java
Jan 6, 2015I'm making a stock system for the heck of it,so everything was going great until I hit the loop I am trying to use a for loop to add stock to the stock system,any way the question is maily about loops.How come I cannot declare a variable outside a loop and assign a value to it,for example I can declare as follows and I will not get an error,
for(int i=0;i<10;i++){
System.out.println("example");
}
but in my code(and yes its the only error I get I tested it) I get an error and can only declare and assign a value inside the loop,the reason for this is because I wanted to get the value from another class and use it in the loop ok so heres the code from both classes.
public class mainn{
public static void main(String [] args){
stock first = new stock();
int internal;
internal = first.wanted;

Building A Registration System
Jan 18, 2015I'm assigned along with two others to make this program for a project.
We need to store data to the program by adding them such as user_id among the 5 criterias that are needed. Lets say I want a new user, I need the program to give me that option and then I would type in the user id and the program would store that data information
As far as I'm aware, boolean, screentokenizer and scanner is involved in the making of this program.

90-Point Version Specifics: The 90-point version requires that you write both the fromHexToBin and fromBinToDec methods.
90-Point Version Output
95-Point Version Specifics {The 95-point version requires everything from the 90-point version and adds the fromBinToHex method. For this version, you may assume that the binary number will have a multiple of 4 bits.
95-Point Version Output
100-Point Version Specifics: The 100-point version requires the same methods as the 95-point version; however, the fromBinToHex method needs to be improved so it can convert regardless of the number of bits.
100-Point Version Output
105-Point Version Specifics: The 105-point version requires everything from the 100-point version and adds the fromDecToAny method. For this version, the method needs to be able to convert from decimal to any base between 2 and 10. Base 16 is not required for this version.

Digital Signage System
Jul 1, 2014I am going to try and write a server-client based system.The server will be the design of what I want (e.g: daily advertisements that will be displayed on big monitors connected to the client, with like a slideshow looping). The client will just be receiving information from the server and not doing anything with it except displaying it and perhaps a networking element of the client reporting back to the server if the connection is dropped etc. The administrator can use the server to change the look of the advertisement.
I need the server to PUSH OUT to the client computers.I am on a networking degree so there has to be some elements to networking connections going on and programming is not my strong point. Would I write the server and clients in Java or another program? Will there need to be a "middle" program such as a web server?

if (stuAverage > stuAverage2 ){
System.out.println(student + " has the highest grade of all students entered!");

Java Dicing System With Currency
Jul 31, 2014I have been working on making a Java application for the Game RuneScape. My goal is to make an Application to where you register on the application and it saves the information in a file. I am also looking to make it so you can transfer money from Runescape to your Account on my Application by submitting a ticket. When you submit a ticket you get assisted by one of the moderators, they trade you in the game and take the money, and then they take that money out of their current account. Admins are allowed to give moderators money via their account or another method. My issue is creating the ticket system. I want to be able to do this all via the application. So basically what i have currently for the application is a chat room, with different rooms available to go into by the users. So I need to make the tickets show up only to Moderators and Admins in the general chat room.
View Replies View RelatedListing System Properties With A Linebreak
Apr 6, 2014I am quite new to java and trying to print all the system properties with the following
code:System.out.println(System.getProperties());
This prints all the properties as expected but I am wanting to put each property on a new line and am struggling a bit. Obviously I will need some sort of for loop etc but im just not sure how to do it. Is it something along the lines of:
for (int i = 0; i < System.getProperties().size(); i++){
What my understanding of what the above is doing is checking how many properties there are an looping round for each property that exists, so all I need to do is get the property 1 at a time however I am not sure where to get the property value to input into the System.getProperty(); method.
Roots Of Nonlinear System Of Equations
Oct 10, 2014I am in search of a library that has been created in JAVA that can be utilized to solve for roots of a nonlinear system of equations. Each equation has 2 variables, x and y, and will need a library that uses higher calculus equations. No ones that just solve for x.
Most of the libraries that have been created to solve nonlinear equations are either in Fortran, C, or Python. There are a few libraries such minpack/scipy. The only libraries that I have been able to find or programming solutions that are in JAVA either require additional programs such as Matlab or are commercial products
I did find one library put together by a professor in Colorado State, but am unsure how to use it. There does not seem to be a way to enter your functions in the code.

How to use this library or find a library that can be used in an android application would be amazing.
Audio-system Can't Find Any Mixers
May 13, 2014I've moved working code over to a different computer, a 32 bit Dell PC running Win7 under Netbeans and Java 8. I can't get it to play or synthesize any sounds because it can't get any Mixers. I tried adding the standard provider entries to the sound.properties file (they aren't needed in my other computer, but I had to try), and it made no difference. I've tracked down the problem farther by getting the source code for these classes and stepping through.
The system seems to have the Mixer providers, but in java.util.ServiceLoader.LazyIterator$nextService() it is looping through a set of javax.sound.sampled.spi.MixerProviders and it hits the following error:
try {
S p = service.cast(c.newInstance());
providers.put(cn, p);
return p;
} catch (Throwable x) {
fail(service,
"Provider " + cn + " could not be instantiated",
x);
}
why this is happening?

Also, I would like a tilt similar to Clash of Clans. How do I do this?
