Plese help! Stuck on some basic Java homework...

I am taking this introduction to java class and we were given 3 homework assignments and I am really stuck on 2 of them.
One of the assignments asks to make a index.html page that will connect to a mysql database for coffee/suppliers.
The first part says:
Create the index.html to create the following web page. After a user selects
Espresso and 5 pounds, and clicks �Submit Order� button, he/she is going to see the
following URL:
http://localhost:8080/hmwk09/coffee_processing.jsp?name=Espresso&pounds=5&Submit=Submit+Order
(which I sort of completed physically with dreamweaver. im not sure if i need to embed some java into that page.)
The second part which I am really stuck on says:
Create the coffee_processing.jsp that queries coffees and suppliers table (you created in homework 08) to display the following page:
This part is where it queries the mysql database that I did. The page is basically supposed to look like this (in a webpage format):
Here is the information about your order:
| Name | Supplier | Price |
| Espresso | The High Ground| 9.99 |
Number of Pounds: 5
Total Price: $49.95
(I really confused on what I need to do to create a jsp to do this. Thanks so much in advance!)

well, first create a jsp page that defines how the page will look. Then make use of a <jsp:useBean..> in combination with <jsp:getProperty....>
and <jsp:setProperty....> to access a bean that does the database fetching.

Need to talk through some basic Java principles

I know this is asking a lot, but I need to talk to someone about Java basics. I have an interview coming up. I am studying, but really need to talk through some things with someone who is familiar with Java programming. My email address is [email protected] If someone could send me a telephone number and perhaps spend 30 minutes on the phone, I would be very greatful. Thanks!

I don't know if there are any forums where they help you fake your way through interviews.

1041N-A-K9 help in doing some basic setup

Hi,
I'm new with setting up CISCO AP, I'm used to GUI and that's what I'm using to set this AP. How my network set is :
ISP Modem/Router (disable radio and set it where DHCP start at 192.168.15) ----> CISCO SG300-28P (Set static IP, upgrade fimware) ----> CISCO 1041N AP (Set static IP, 12.4 firmware).
I have 50mbps down and 25mbps upload speed from ISP, when using their router radio...speedtest.net showed just exactly that...but when using the 1041, I get half of it. It also seems that the GUI is rather slow and stubborn, often it doesnt save settings I selected and rather confusing to use, as the express setup is nothing like "express", you need to go to many different setting to get the radio up. Like it wont allow me to use WPA encryption without RADIUS...I dont have any RADIUS server (I can set up RADIUS with my Synology NAS...but is it really neccesary?)
...also the DNS....DHCP is controlled by the ISP router.
Anyway my question :
1) I've been looking for tutorial to set this AP through GUI and mostly is in CLI...how do you enable WMM for one?
2) This AP doesnt seems to perform as well as the integrated radio, what is so special about this AP beside the CLI for advanced config?
3) I'm planning to use another bran AP in conjuction with this AP, planning to use the same SSID and password...do I need to set them using different channels? I have 2.4ghz phone also, which channels should I choose?
4) I set the AP with static IP, the router provide DHCP service....is there any setting where I should be disable the DHCP service on the AP?
My plan is to get a secure, fast and stable service...that is why I choose this setup...but it's been a time consuming just to set this AP to do basic stuff. The Ubiquiti AP I've set before, just took me 15-30 min to set....this?It's been 6-12 hours with medicore performance...

Hi Scott,
I'm still no where with the CLI atm, tried to upgrade the firmware through HTTP and the pop up just saying :
This window is polling the system for upgrade status
Current status is:
IDLE: Restart completed.
Copyright (c) 1992-2009 by Cisco Systems, Inc.
3
Please wait...
The system is upgrading the software and restarting. This should take between 5 and 15 minutes depending on your network speed. Do not interrupt the upgrade or attempt to access other web pages on the AP during this process.
time elapsed been leaving it all night....the firmware is not updated yet....am I doing something wrong? (disable radio, access the AP with IE and system software, upgrade...find the new firmware and hit install)

Some basic java Questions

class overload
void test (long a)
System.out.print("\n\t\t Inside Integer..."+a);
class usetest
public static void main(String args[])
overload ob=new overload();
double i=88;
int j=54;
//ob.test(i); this do not work
ob.test(j); // works
The one that do not work when typecasted works why? When method having same parameter is not present what java compiler do?

The compiler will automatically perform a "widening" cast for you, i.e.
a cast from one type to another where no precision is lost. If you supply
an int and a long is wanted, the int will be cast to a long type.
Not so from double to long because that isn't a widening cast, it's a
"narrowing" cast because bits might get lost after casting. You have
to cast that double to a long explicitly, thereby telling the compiler that
you know what you're doing.
kind regards,
Jos

Storage rules for an editing rig. Some basics.

How do you set up your editing machine in terms of disks for maximum performance and reliability? (SSD's are left out here.)
This is a question that often arises and all too often one sees that initial settings are really suboptimal. These rules are intended to help you decide how to setup your disks to get the best response times. Of course the only disks in an editing machine must be 7200 RPM types or faster. No GREEN disks at all.
Rule 1: NEVER partition a disk. You may ask why? First of all, it does not increase disk space, it just allocates the space differently. However, the major drawback is that for a partitioned disk the OS must first access a partition table at the beginning of the disk for all accesses to the disk, thus requiring the heads to move to the beginning of the disk, then when it has gotten the partition info move to the designated area on the disk and perform the requested action. This means much more wear-and-tear on the mechanics of the disk, slower speeds and more overhead for the OS, all reducing efficiency.
Rule 2: Avoid using USB drives, since they are the slowest on the market. Do not be tricked by the alleged bandwidth of USB 2.0 advertisements, because is just is not true and remember that the alleged bandwidth is shared by all USB devices, so if you have a USB mouse, keyboard, printer, card reader or whatever, they all share the bandwidth. Stick to SCSI or SATA disks or e-SATA. If needed, you can use Firewire-800 or even Firewire-400 disks, but they are really more suited for backups than for editing.
Rule 3: Use at least 3 different physical disks on an editing machine, one for OS/programs, one for media and one for pagefile/scratch/renders. Even on a notebook with one internal drive it is easy to accomplish this by using a dual e-SATA to Express card connector. That gives you an additional two e-SATA connections for external disks.
Rule 4: Spread disk access across as many disks as you have. If you have OS & programs on disk C:, set your pagefile on another disk. Also set your pagefile to a fixed size, preferably somewhere around 1.5 times your physical memory.
Rule 5: Turn off index search and compression. Both will cause severe performance hits if you leave them on.
Rule 6: If the fill rate on any of your SATA disks goes over 60-70% it is time to get a larger or an additional disk.
Rule 7: Perform regular defrags on all of your disks. For instance, you can schedule this daily during your lunch break.
Rule 8: Keep your disks cool by using adequate airflow by means of additional fans if needed. You can use SMART to monitor disk temperatures, which should be under 35 degrees C at all times and normally hover around 20-24 C, at least in a properly cooled system.
Rule 9: If people want raid, the cheapest way is to use the on-board IHCR or Marvell chip, but it places a relatively high burden on the CPU. The best way is a hardware controller card, preferably based on the IOP348 chip. Areca ARC and ADAPTEC come to mind. 3Ware uses it's own chipset and though not bad, they are not in the same league as the other two. Promise and the like in the budget range are no good and a complete waste of money. Expect to spend around $ 800 plus for a good controller with 12 connectors internally and 4 e-SATA connectors. Important to consider in a purchasing decision is whether the on-board cache memory can be expanded from the regular 256/512 MB to 2 or even 4 GB. Be aware that 2 GB cache can be relatively cheap, but the 4 GB version extremely costly ($ 30 versus $ 300). For safety reasons it is advisable to include a battery backup module (BBM).
Rule 10: If you can easily replace the data in case of disk failure (like rendered files), go ahead and use raid0, but if you want any protection against data loss, use raid 3/5/6/10/30/50. For further protection you can use hot spares, diminishing downtime and performance degradation.
In general when you get a new disk, pay close attention to any rattling noise, do perform regular disk checks, and in case of doubt about reliability, exchange the disk under guarantee. Often a new disk will fail in the first three months. If they survive that period, most of the disks will survive for the next couple of years. If you use a lot of internal disks like I do (17), set staggered spin-up to around 1 second to lessen the burden on the PSU and improve stability.
Hope this helps to answer some basic questions. If not, let me know. Further enhancements and suggestions are welcome.

...well, it is a northern D - they call us often "Fischköpfe" because we love to eat fish here in Hamburg!
I just have summarized a bit the storage configuration I am thinking of
RAID Type
Objective
System requirements
RAID level
Offline Storage
store a whole video project (1h of 4k material requires about 128 GB)
needs to be highly reliable (redundancy is a must);
doesn't need to be extremely fast;
discs can be cheap because they don't have a high burden (just upload & download) to the video RAID.
10
Video RAID
store material for a day work
fast and reliable
10
Installation RAID
just to install Windows XP with CS4 Master Collection
redundant but speed isn't critical here
1
Working RAID
for page-file/scratch/renders
as fast as possible
disc failure isn't a big problem
0
In order to realize this, I am thinking of the following configuration
RAID Type
number of discs
Type
GB/disc
tot. storage [GB]
usable storage [GB]
cost [€]
Offline Storage
8
SATA
1500
6000
4800
900
Video RAID
6
SCSI/SAS
300
900
720
2100
Installation RAID
2
SCSI/SAS
36
36
30
200
Working RAID
4
SCSI/SAS
147
580
470
1000
Here are my assumptions and constraints:
I only have 6 bays for the Installation - and working RAID;
For the video RAID I also would like to reuse an enclosure, which just has 6 bays;
I would need to buy a NAS enclosure - so here I am open minded and just assumed 8 bays;
the usable storrage I estimated as 80% of the total storage;
discs, which are used heavily should be SCSI or SAS - I am thinking of the Cheetah 15K
Looking into the cost associated, I hit 4000€ easily just for discs. Ok, I can reuse some discs and enclosures, which I have here - but since I need to purchase the NAS enclosure (with 8 bays), which will also cost 1000€ additional, I will use 25% of my foreseen budget for storage.

Doubts in XI basics..help me with some practical examples

hi friends,
I am new to SAP XI have some basic doubts. Answer my questions with some practical examples.
1. what is meant by "Business System" and what is difference between client,customer,Business partner,3rd party
2.If a small company already using some systems like Oracle or peopleSoft,if it wants to use SAP products then what steps it has to follow.
3. SAP system means a SERVER?
4.SAPWebAs means a server software?
5.R/3 system comes under SAP system?
6.XI is also one of the SAP module..how it relates to other modules.
7.In one organization which is using SAP modules,each module will be load in separate servers?
8.PO(purchase order) means just looks like one HTML file..customer will fill the form and give it.like this,Combination of many files like this is one SAP module.Is it right assumption..?if so,then what is speciality SAP?
I have an theoretical knowledge about IR and ID and SLD.what are general business transactions happens in any business ?(like who will send cotation,PO) give some practical example for what actually happens in business?..who will do what?and what XI will do?

Hi Murali,
 1.Business System
Business systems are logical systems that function as senders or receivers within the SAP Exchange Infrastructure(XI).
Before starting with any XI interface,the Business systems involved has to be configured in SLD(The SLD acts as the central information provider for all installed system components in your system landscape.)
business system and technical system in XI
2.Third Party
http://help.sap.com/saphelp_nw04/helpdata/en/09/6beb170d324216aaf1fe2feb8ed374/frameset.htm
eg.For the SAP system a Bank would be a third-party which would be involved in interfaces involving exchange of data(Bill Payment by customer).
3.XI(Exchange Infrastructure)
It enables you to connect systems from different vendors (non-SAP and SAP) in different versions and implemented in different programming languages (Java, ABAP, and so on) to each other.
Eg.If an interface involves Purchase Order sent from SAP system to the vendor(Non-SAP system)then,the vendor might expect a file.But the Data is in the IDOC(intermediate document) form with the SAP system.Here XI does the work of mapping the IDOC fields and the File fields and sends it to the vendor in the form of a file.
In short,always the scene is Sender-XI-Receiver.
The Sender and the Receiver depends upon the Business you are dealing with.
4.Business Partner
A person, organization, group of persons, or group of organizations in which a company has a business interest.
This can also be a person, organization or group within this company.
Examples:
Mrs. Lisa Miller
Maier Electricals Inc.
Purchasing department of Maier Electricals Inc.

Need Help with Java Homework

This is my first post here, seeking some help with my java homework. I am required to create a program to write out a receipt for a pizza company: name of company, total number of pizzas, costs (including tax etc), and print out the receipt after taking an order from the customer.
This is a beginner's java class and my book isn't very good at explaining (mainly because it says "will be discussed in ch 14" when we're in ch 1-3 and it's an essential part of the program).
But anyways, if anyone is up right now, would be helpful for some help. I have a general idea of what I wanna do, but the program so far is very messy and incomplete and having trouble getting it to look nice and proper.

well there were two ways of doing this, im only 2 weeks new in java so bear with me.....I was gonna set 3 classes, one appclass, one order form, and one receipt. I was told you can combine the order and receipt in 1 class, but I thought doing 3 woudl be better to help me learn more...anyways, I haven't worked on the appclass yet, but for the order I have a very messy set of codes. I know that it's wrong but it's a start, im looking for any input cause the book does not explain very much.
For the order class, I will be doing showinputdialog boxes for how many pizzas, the sizes, and the toppings. Here is what I have so far ( i know it is VERY messy and disorganized but I am a bit lost in where I should go next):
* @author AlexNguyen
* To take the order with number of pizzas and toppings
package project2;
import javax.swing.JOptionPane;
public class Order {
     public int NumberOfPizzas;
     public char Pepperoni;
     public char Sausage;
     public char Cheese;
     public Order(int n) {
     NumberOfPizzas = n;
     JOptionPane.showInputDialog("Enter Number of Pizzas"));
String ptype; {
     public void start();
     public void takeOrder();
     public void writeReceipt();
          public void takeOrder();
          ptype = Topping
public String selectPizza(char P, char S, char C) {
     Pepperoni = P;
     Sausage = S;
     Cheese = C;
public void numPizza(int numberOfPizzas) {
     num = numberOfPizzas;
JOptionPane.showInputDialog("Topping for Pizza?");
JOptionPane.showInputDialog("Pizza Size?");
JOptionPane.showInputDialog("Number of Pizzas?");
}

Some basic questions: Help defining Real World Classes

I am trying to write a small applet using proper OO concempts and Java technique and I'm confused on the proper way to do this. I think I know several ways that work and have all the peices I need such as JMail and JDBC drivers, but would appreciate help on understanding how to properly structure my classes and objects.
The application will simply do the following: I have a database table that receives a new entry when a truck is late for its delivery. When this new record is created, I need to send an email to the driver manager who will then decide (via a jsp page) whether the customer should receive an email about the late delivery. For each truck, there will only be one driver manager and one client to be notified.
What I'm confused about is what classes and objects to create (and why). My first thought is to create a LateTruck class, a DriverManager class and a Customer class and have the LateTruck class call up the DriverManager to send an email then have the JSP page reinstantiate the LateTruck and instantiate the Customer class to send the email to the client.
If I do it this way, is there a proper way to send the email? Do I send the email as a method in LateTruck which gets the email address from DriverManager such as
LateTruck.Order1234.SendEmail(DriverManager.JoeBlow.Email)
or do I use LateTruck to write the email message which I then pass to DriverManager such as
DriverManager.JoeBlow.SendEmail(message)
Should I even break up the applet into three classes and objects? Since each LateTruck only needs one DriverManager and one Client, is the proper way to do this to create only one class called LateTruck which has DriverManager, DriverManagerEmail, ClientName and ClientEmail all as properties of LateTruck?
Thanks for any help in understanding the basics here.

Is that the story of Static Write and the Seven Classes and the evil stepmother Wilma Gates who kept asking "Mirror Site, Mirror Site on the web, who's got the buggiest InterDev?

Some basic help in Threads

Hi all,
I have some basic problem regarding use of thread.I have a class A (with main method )which creates 5 instance of class B say b1,b2,b3,b4,b5.This class B extends thread.
Now within main of A i spawn 5 thread by calling b1.start(),b2.start(),b3.start(), b4.start(),b5.start().
Now contraint is at any time A can spawn only 5 threads.For this there is another class C that has private variable count and 3 synchronised method one which increments count , second one decrements count,third one returns count and same instance of this class is pass to each of the thread.
Before terminating each thread calls decrement method of this object .
After spawning 5 thread main thread sleeps for some defined time and whenever it wakes up it checks if count is less than 5 if yes then it spawns new thread and call increment method.
Now i want to avoid the logic of main thread sleeping for some defined time than waking up checking value of count and rather want a logic in which main thread sleeps and wakes up only when one of the thread terminates.Thus unnecessary checking of value of count is avoided.
There must be way for this because this is very common problem which many of you might have faced.I have simplified by problem because this is one of the concept on which design of my application depends.If any one has found some tutorial or code example which describes similar problem then kindly let me know.
Regards,
beginner83.

Hi all,
I have some basic problem regarding use of thread.I
have a class A (with main method )which creates 5
instance of class B say b1,b2,b3,b4,b5.This class B
extends thread.Well, that's not a good start. It's generally not a good idea to extend Thread, instead the class with the Thread's execution run method should implement Runnable and be attatched to a Thread object when the Thread object is created.
Now within main of A i spawn 5 thread by calling
b1.start(),b2.start(),b3.start(),
b4.start(),b5.start().
Now contraint is at any time A can spawn only 5
threads.For this there is another class C that has
private variable count and 3 synchronised method one
which increments count , second one decrements
count,third one returns countSo how about a method to the class which causes the calling thread to wait while the thread count is five or more. Then your main method can include this in it's thread-starting loop.
See Object.wait and Object.notifyAll().

Knight tour programming with only basic java

i had this assignment from school which ask us to create a program to calculate how many posssibilities to complete knight's tour from a position using basic java and not using applet. So far i can only create an incomplete program which can only go a speccific way and is also incomplete. i am trying to understand the jaava applet type of knight tour program but got too confused as i have just started learning this. Please help me with this.
here's my code:
public class uk16638_a3{
 public static void main(String[] args){
 int horizontal[] = {2,1,-1,-2,-2,-1,1,2};
 int vertical[] = {-1,-2,-2,-1,1,2,2,1};
 int chessBoard[][]=new int[8][8];
 int move, currentRow = 0, currentCol= 0, move_count = 0, new_vert, new_horz;
for(int i=0; i<8; i++)
 for(int j =0; j<8; j++)
 chessBoard[i][j] = 0;
chessBoard[0][0] = 1;
do{
for(move=0;move<8;move++){
new_vert = currentRow + vertical[move];
new_horz = currentCol + horizontal[move];
if ( (new_vert>=0) && (new_vert < 8) )
if( (new_horz>=0) && (new_horz < 8) )
if( chessBoard[new_horz][new_vert]==0 ) {
chessBoard[new_horz][new_vert] = 1;
move_count++;
currentRow = new_vert;
currentCol = new_horz;
}}}while(move<8);}}

Sorry with the inconvenience cause i am new with this forum so i am causing many problems to all of you. here's the full code i put but i would really like to ask someone to teach me on creating a backtrack and let the knight moves following a different sequence from the one i already set.
public class uk16638_a3{
public static void main(String[] args){
//the movements of a knight horizontally and vertically
int horizontal[] = {2,1,-1,-2,-2,-1,1,2};
int vertical[] = {-1,-2,-2,-1,1,2,2,1};
int chessBoard[][]=new int[8][8];
int move, currentRow = 0, currentCol= 0, move_count = 0, new_vert, new_horz;
//setting all elements in the array to 0
for(int i=0; i<8; i++)
for(int j =0; j<8; j++)
chessBoard[i][j] = 0;
//the knight starts here
chessBoard[0][0] = 1;
//using do while loop, i try to move the knight following the sequence i had already set in the array above. But because its moving at the same direction all the time, it gets stuck.
do{
for(move=0;move<8;move++){
//setting the new coordinates for it to move to
new_vert = currentRow + vertical[move];
new_horz = currentCol + horizontal[move];
if ( (new_vert>=0) && (new_vert < 8) )
if( (new_horz>=0) && (new_horz < 8) )
//new position check if its already occupied or not, if occupied it will move on to the next part of the move sequence i set
if( chessBoard[new_horz][new_vert]==0 ) {
chessBoard[new_horz][new_vert] = 1;
move_count++;
//current coordinate of the new knight position
currentRow = new_vert;
currentCol = new_horz;
}}}while(move<8);}}

Missing some basic functionality

I seem to be missing some basic functionality, like switching to tty1-n using Ctrl+Alt+F1-n. I can't begin to guess what this is related to, as after several installs I've never experienced that to be missing. Can anyone point me in the right directions? Thanks.

Hm. I don't actually have that file in the policy directory.

HELP NEeded in creating tis java program

what do do??

so can some 1 help me"Help" as in provide workable code? They might - you did all right in your last
thread. Personally, though, I doubt you're much helped by this.
Start by reading the description of what your code must do. Make sure you
understand the description - perhaps by explaining it in your own words to someone
else. If they don't understand then you don't understand: not in any sense
that matters.
Then proceed to write some code. The first sentence of the description you posted
makes a good starting point. Write some code that compiles and does this.
Make sure you understand what each line does before moving on.
If you get stuck post some code and an actual question. If there is a compiler error,
copy paste and post the actual error you can't understand and say which line it refers
to. If your code compiles but has unwanted, unexpected or mysterious results,
say what it does and what you were expecting, or wanting.
Hope that helps.
(My apologies if your native language is not English, but really. Use a
dictionary - online or, better, in paper form. Eschew abbreviations. Read what you
post aloud or, as above, to someone else who can tell you if it makes no sense.)

Plese help! Stuck on some basic Java homework...
