For some reason while unmarshalling something you get this error
Solution is:
Instead of

javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance("oasis.names.specification.ubl.schema.xsd.invoice_2");
or
JAXBContext context = JAXBContext.newInstance(inv.getClass().getPackage().getName());

Use a notation like this

javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance(oasis.names.specification.ubl.schema.xsd.invoice_2.InvoiceType.class);

Where InvoiceType will be the thing you [...]

After initializing xsd with JAXB Binding on Netbeans, you can use a method like this.
Both JAXB binding and schema are same but as far as i see, JAXB unmarshalling doesn’t validate XML, it just transforms it.

package unmarshallertest;

import java.io.*;
import javax.xml.bind.*;
import javax.xml.validation.*;
import oasis.names.specification.ubl.schema.xsd.invoice_2.*;

public class Main {
public static void main(String[] args) {

Trying to write multi-user applications, the need of a server always disturbs me
It would be good to achieve a connection between two peers without openning a port, for example in web applications, without going through server
For this reason i searched about P2P a little bit
The best solution seems to be JXTA
I thought maybe it may [...]

My first post describes how to deploy a JavaFX application to Facebook but I realized that it gives some errors on most computers, and it is not very practical
Here I will give a more clear example
My application is a Sudoku Solver, you can see it from the Pages of my site
One major problem that i [...]

Here is another chat program, using JavaFX for GUI and Java on the background for SQL transactions.
One thing I realized is that you can’t bind to variables from JavaFX to Java Threads.
Using timelines instead of threads are better.
Code is pretty self explanatory:
( You should add mysql-connector-java-5.1.7-bin.jar (or newer) mysql library in order to connect mysql [...]

It is probably the worst code I have written but it is the first time i use SQL.
The program just inserts messages into a table than updates the textarea by querying for all the messages.
There is an ID option in table for the use of session. If modified a program can only see the messages [...]

The task was to search for a tag including a given string

<something> stringtofind </something>

if we are searching for “stringtofind”, “something” is an answer
Here is the code:
Main.java:

package xerxes;

public class Main {

public static void main(String[] args) {
getTagname outp=new getTagname("http://kaansoral.com/deneme.xml","abidin");

There is no operation precedence on generated expression, number at any state can’t be

Problem Statement
Some of the input outputs in raw form
Inputs:

a=(new 10)

c=insert ((2,3),(8,9)) (new 10)
d=delete ((5,5),(5,5)) (delete ((8,1),(9,8)) (negate (new 10)))

The task is to implement dynamic binding for function calls.
Returning error outputs is a little bit tricky.
Other than that, fullfilling requirements is not so hard with functional programming.
When a new function call (CallFunc) comes, the scopes list is updated with that functions own declerations.
When that function call ends, our own scope list is [...]
