JSF :: Some RowSet Info Not Being Displayed?
Apr 22, 2015
I am reading from a database(SQL Server 2012) and storing that information in a ResultSet. I am then trying to display that information using a DataTable.
Here is my managed bean
/*

package clientspage;
import java.io.Serializable;
[Code].....
The ID and the commandLinks are being displayed but the Client is not.

I am new to java and attempting to write a method that will insert data from a cachedrowset into an MS Access 2010 database table. My goal is to use this code that will accept any kind of Oracle SQL table size with different kinds of values and insert them into MS Access.
After I ran the code I get an error message below. By process of elimination i was able to find the issue is coming from the method called "insertAccessTable" somewhere in the while loop area "while (CRS_insertAccess.next())", but I am stumped on how to resolve this issue.
java.sql.SQLException: Parameter-Set has missing values.
Below is my Oracle SQL test table that I used for this exercise.
create table book (
TITLE_ID CHAR(3 BYTE)
TITLE_NAME VARCHAR2(40 BYTE)
TYPE VARCHAR2(10 BYTE)
PUB_ID CHAR(3 BYTE)
[Code].....

I am using CachedRowSet returning it from a parameterised select statement and it works fine.
If I put the same select statement into a simple read-only stored procedure then I get this exception: "A result set was generated for update".
I am not trying to update the rowset in my code.
I tried to make the CachedRowSet to be read-only but it does not work, same error.
Question 1 : can a stored procedure returning a single result-set be called to populate a read-only CachedRowSet? (in a similar fashion to a CallableStatement prepareCall method with input/output parameters).
Question 2: in general is using CachedRowSet, WebRowSet, FilteredRowSet (disconnected) and JDBCRowSet (connected) something to be encouraged for future develpment or are they deprecated, or replaced by something else/better??

I'd like to know how to,
1. Connect to Google,
2. Search for something,
3. Return a SCREEN SHOT of the results.
I'm assuming this involves loading the webpage into a JFrame, or is there an easy workaround?

I want to ask that, when a server listen to A port and it accepts a request from a client then the server accepts the request using accept method,but how does the server get the info about the client like wat is the port no and ip address of the client,I read a answer regarding this that Server never gets the port no of client only the ip address and it connects to client using a connection stream but as far I know from networking, a device must have the ip address and port no of the device it wants to connect to.

Suppose there're two classes: Exam and MainExam (contains a main method). class Exam has a constructor public Exam(String firstName, String lastName, int ID). Class MainExam reads data from a textfile. For example, the data can be: John Douglas 57. How can one pass data to the constructor from a textfile?

Let's say I'd like to print out something as a prompt without end with a new line char, so the standard System.out.println() is not an option and I'd like to find something else inplace of println().
Where to find that? I googled about that and learned printf() is the one I want, but how to get it from java api documentation.

I was trying to make a UDP voice chat but i couldn't make the receive method work! so i just move on to work with TCP. I found a simple code that i found it pretty easy to understand,but i couldn't make it work, always stuck within exception.
Here is the output I got:
Available mixers:
Java Sound Audio Engine
Microsoft Sound Mapper
WinOS,waveOut,multi threaded
java.lang.IllegalArgumentException: Line unsupported: interface TargetDataLine supporting format PCM_SIGNED, 8000.0 Hz, 16 bit, mono, little-endian, audio data
And here is the code
sender:
Java Code:
package sender;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import javax.sound.sampled.AudioFormat;
[Code] ....
I tried to play with the index of mixerInfo array in the line
Java Code:
Mixer mixer = AudioSystem.getMixer(mixerInfo[1]); mh_sh_highlight_all('java');
But nothing happened. How I can fix that?

I am trying to invoke some methods in a for loop in order to print some info stored in a List. But for some reason, compiler pops a message saying "cannot find symbol - method getEmpID(). You are using a symbol here (a name for a variable, method or class) that has not been declared in any visible scope." But I am pretty sure that method getEmpID (as also getName(), getAfm(), and payment() ) have been declared as public.
Note: My List contains objects of different type (SalariedEmployee, HourlyEmployee). I hope this is not the factor causing this problem.
Java Code:
import java.util.*;
abstract class Employee{
private String name = "";
private String afm = "";
private long EmpID;
static long count=0;

I've got a nasty nullpointer that I have tried to resolve to no avail as of yet. The program should prompt for a listings.txt file and take its info and write to a report file. Here's the stacktrace:
run:
Input file: listings
Exception in thread "main" java.lang.NullPointerException
at java.io.Writer.<init>(Writer.java:88)
at java.io.PrintWriter.<init>(PrintWriter.java:113)

at kettask2b.PropertyListingsReport.main(PropertyListingsReport.java:34)
Java Result: 1
Some adjustments that I have attempted are:
BufferedWriter pwfo = null;
for (int i = 0; i < args.length; i++) {
String string = args[i];
pwfo = null;
[Code] ....
Here's the code:
package kettask2b;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;

I am writing this program for my Java level 1 class. I am able to get it to compile and run, however nothing is outputted. Below are the instructions and the code that I have written.
Instructions:
Write an application that calculates and displays the amount of money a user would have if his or her money could be invested at 5 percent interest for one year. Create a method that prompts the user for the starting value of the investment and returns it to the calling program. Call a separate method to do the calculation, and return the result to be displayed.
Below is the code that I have written
import java.util.Scanner;
public class Interest
{
//main method
public static void main(String[] args)
{
originalAmount();
Scanner input = new Scanner(System.in);
[code]....

I have a empty JList in which I hit a button LOAD DATA which should load all the data. but once I load data i try to fill in the List but I keep getting errors.
String[] aos = new String[itrList.size()];
itrList.toArray(aos);
//JList listFAIL = new JList(aos);
//list = new JList(itrList.toArray());
//list.removeAll();
list.setListData(aos);
JScrollPane s = new JScrollPane(list);
I have tried doing setListData and i get a error;
And if i do new Jlist it doesn't change the data.
The List does fill as i have a checker for that.

Trying to get an image to display in a GUI.
try {
ByteArrayInputStream in = new ByteArrayInputStream(
transferWorker.bOutput
.toByteArray());
BufferedImage bufferedImage = ImageIO
.read(in);
[Code] ....
But nothing is happening in the GUI. I have stepped through and bufferedimage contains the data, but its not being displayed. Whats happening is, an image is being transmitted to serial port of laptop, so i'm taking it in and storing it in a BufferOutputStream and then trying to open it in my GUI class.

Basically I want to align the AM traffic incidents under the heading "AM" but am not sure how to accomplish this. I am using separate arrays for all three of these types of information and need the info to line up with their respective titles.

I am trying to get items to display that would display in a command prompt now into a GUI. I am freaking lost at the moment, probably because I've been staring at this code for over a week now. I have included all the files that are necessary to run the program as an attachment for your own testing purposes. Should I be using a TextField to display the data from the CSV files? How do I get the data to be displayed? How would I get it to be displayed based on the different files Staples (newSTPL.csv), Apple (newAPPL.csv), and Microsoft (newMSFT.csv)?
Java Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
/**
* DataAnalyzer Class
* This class instantiates the methods from the ReadFiles Class and Calculations Class.

Just some sample code:
Java Code:
mainPanel.add(background, new Integer(10));
cards.add(king[0] = new Card(200, 200, TILE_SIZE, TILE_SIZE, 0, 0)); mh_sh_highlight_all('java');
Then, when a card is created, it calls:
Java Code: Main.mainPanel.add(this, new Integer(1)); mh_sh_highlight_all('java');
Yet for some reason, the background is always painted OVER the card UNLESS I set the background to -1.
