What is Sun referering to in the following?

Hi,
I was looking through the Sun tutorial for firewall related material (i'm having problems getting my applet to talk to a servlet on the other side of a firewall) and came accross this:
"Point the browser at the applets linked to by this page. You should be able to see at least the first applet. The second one might not show up, or might show up without images, due to firewall issues with the way it's packaged. "
This is at the following url:
http://java.sun.com/docs/books/tutorial/uiswing/start/swingApplet.html
Near the bottom of the page. What are they talking about?
Thanks
Andre

They simply mean that you should see two applets on that page, this shows you have successfully installed the java plug-in.

HT3275 What if my error message is the following: The backup disk image "/Volumes/********'s Time Capsul/****'s MacBook Pro.sparsebundle" is already in use. (I have redacted the name of the computer with asterixes)

What if my error message is the following: The backup disk image “/Volumes/********'s Time Capsul/****’s MacBook Pro.sparsebundle” is already in use. (I have redacted the name of the computer with asterixes)

This is a complex procedure.
Pull the power cord from the back of the Time Capsule
Wait a minute or two
Plug the power cord back in to the back of the Time Capsule
This will fix the issue 98% of the time. If you are in the unlucky 2% category, more help is here from Pondini, the Time Machine guru:

Thank youHi Frank,
in this example the Customer is the Java class of objects which are put into a cache and is not Coherence specific at all. This is just the return type similarly to how a (stored) function in Oracle may return a row-type containing multiple values.
The return is a Java keyword which in a non-void method instructs the JVM to return the value of the expression following it from the method as the method return value if an expression follows it, and in a void method it simply returns from the method (no return value in this case, similarly to stored procedures).
Sorry for my saying so, really no offense intended, but judging from your questions you might want to attend at least a beginners Java course.
Best regards,
Robert

I am unable to find the Firefox button referred to in the following: At the top of the Firefox window, click on the Firefox button and then select Options

Every instruction Mozilla offers to find or to do something contains a term or a phrase that is indeciphrable.
I have been trying to change "Cookie Settings" so of course Mozilla advises me to click the Mozilla button at the top of the page. And of course there is no Mozilla button at the top of the page. Then after wading through Mozilla's arcane and moronic help sections I end up at the following:
Display the Firefox button menu instead of the menu toolbar.
Why don't I see it? (the Firefox button)
Apparently the Firefox button is a new feature added in Firefox 4 to replace the Menu Bar. The menu bar is displayed instead of the Firefox button to make Firefox look like other Windows XP programs. Windows XP? Are you kidding me? Windows XP. Earth to Mozilla: Have you heard of Windows 8 or Windows 8.1?
Then your instructions go on to refer to Windows Vista and Windows 7. JFC!
Then, under "How to get it?" Mozilla offers the following gem:
Right click on an empty section of the "Tab Strip" and uncheck "Menu Bar" om the pop-up menu.
WHAT IS A TAB STRIP; and WHERE IS THE TAB STRIP? Again, JFC!
Since these instructions refer to Windows XP, Windows Vista, and Windows 7, apparently these instructions haven't been upgraded for more than 2 years. No wonder Mozilla is a non-profit organization. There is no way that this organization could ever be profitable under any other structure.

What does this name mean in the following form

Hi guys,
Can anyone please tell me abt the name field and also other field onSubmit does in the following form
<form method="post" action="IAFDispatcher" name="mainForm2" onSubmit="return checkCustomer()">
Thanks in advance.

Hi guys,
Can anyone please tell me abt the name
abt the name field and also other field onSubmit does
in the following form
<form method="post" action="IAFDispatcher"
name="mainForm2" onSubmit="return checkCustomer()">
Thanks in advance.The name field is used for identifying this form on the client side, such as through javascript DOM operations (like document.forms.mainForm2 would locate the form in question).
The onSubmit attribute defines a javascript function that will occur when the 'onsubmit' event of the form is given. The 'onsubmit' event occurs when a submit button is pushed or when a javascript .submit() method is called on the form. The function called my the onsubmit event should return a boolean value: "true" means that submission should continue, and "false" means that the form should not be submitted.

What result would I get for the following?

Assume we have Image object, width and height already.
public int[][] getRedArray()
int values[] = new int[imageWidth * imageHeight];
PixelGrabber grabber = new PixelGrabber(imageobj.getSource(), 0, 0, imageWidth, imageHeight, values, 0, imageWidth);
try
if(grabber.grabPixels() != true)
try
throw new AWTException("Grabber returned false: " + grabber.status());
catch (Exception e) {};
catch (InterruptedException e) {};
int r[][] = new int[imageWidth][imageHeight];
int index = 0;
for (int y = 0; y < imageHeight; ++y)
for (int x = 0; x < imageWidth; ++x)
r[x][y] = ((values[index] & 0x00ff0000) >> 16);
index++;
return r;
Could you please please explain how this code works? brief step-by-step explaination would be satisfied.
Please explain explicitly how "r[x][y] = ((values[index] & 0x00ff0000) >> 16);" this works.
Thank you so much!! :)

Consider the following :
In this case a color is stored as 4 bytes. Each byte holds a color component, namely Alpha, Red, Green and Blue. In that order.
Now, 4 bytes = 1 int. The color is stored in an int, so bits 16-23 hold the red component. If you want to isolate that byte you'll need to do two things :
1) Isolate the "red" bits
2) Move them from bits 16-23 to 0-7
So, if we take the color value in bits, where A, R G and B signify a single bit reserved for an alpha, red, green or blue color component respectively :
AAAAAAAARRRRRRRRGGGGGGGGBBBBBBBBStep 1) is isolating the red :
00000000RRRRRRRR0000000000000000You do this by doing a bitwise AND with operand 1 being the color int, and operands 2 being an integer whose 16-23 bits are set :
color & 0x00ff0000Step 2) is moving the red bits to 0-7 :
(color & 0x00ff0000) >> 16
000000000000000000000000RRRRRRRRNow it's a valid integer value ranging from 0-255 and you can use it, as done in your code snippet.

What solutions would be needed for the following scenario

I have a client who operates two companies.
One company manufactures a specific piece of equipment.
The other company rents, sells and services this piece of equipment. This equipment consists of three major interchangeable components.
They need to track:
Customer information u2013 company name, contact person, start date, end date, sold or rental unit, service schedule on the three major components.
Equipment information u2013 where it is, which components it consists of, service records, forecast of service requirement, data on each specific component.
Job information u2013 field tickets, work orders, distance traveled for installations and service work, how long units have been running.
Revenue information u2013 all pertinent information as well as what was billed and when.
Inventory information u2013 all pertinent information as well as which parts have been used by manufacturing and which parts have been used to maintain the rental assets or service on sold equipment.
They also want to automatically contact operators and client about upcoming service dates.
My expertise is in SAP HR. Which SAP modules would they need to accomplish this? Is there another solution they should consider?

Importing - Exporting Tables, What is best to do with the following;

This is purely down to my general interest, I can do both but just wondered which is best to do?
Export a table / import table / drop table
Export table (truncated)/ import table
Any adverse effects?
To Truncate or not Truncate?
Any advice or comments gratefully received.

Hi,
If your table is going to be the same, you may go for the TRUNCATE approach.
Pros: all blocks assigned to the segment/table are not released (DROP releases space)
that will free the DB of that activity when loading data.
Cons: importing data reorganizes data, usually defragmenting space allocated...therefore you may get some empty extents (that may be used later), this is not preciselly a minus if your table is going to grow: you'll have space preallocated.

Hashtables: What on earth is wrong with the following code!?

I'm loosing my mind here:
[jdk1.4.2]
//random code...
        Hashtable threads = new Hashtable(20);
        threads.put(portNum, ipThread); //portNum is of type int
                                        //ipThread is of type ThreadX, ThreadX extends Thread
//other code...
        ThreadX t;
        t = (ThreadX)threads.get(packet.getPort()); //packet.getPort() returns an INTAnd the compiler returns this:
path>javac *.java
IPServer.java:58: cannot resolve symbol
symbol : method put (int,ThreadX)
location: class java.util.Hashtable
threads.put(destinationPort, ipThread);
^
IPServer.java:67: cannot resolve symbol
symbol : method get (int)
location: class java.util.Hashtable
t = (ThreadX)threads.get(packet.getPort());
^
2 errors
Thanks ahead of time.

From the JDK 1.4.2 documentation
"This class implements a hashtable, which maps keys to values. Any non-null object can be used as a key or as a value.
To successfully store and retrieve objects from a hashtable, the objects used as keys must implement the hashCode method and the equals method. "
I assumed from that an int or double or any other primitive, which implements both the hashCode and equals method, would work.

Ojc will compile the following class. A bug?

I thought that in Java classes cannot be declared protected. ojc will however compile the following class:
protected class aclass
The Sun java compiler prints the following error:
aclass.java:1: modifier protected not allowed here
protected class aclass
Is this a known bug in the Oracle Java compiler?

Yes, it seems we have a little bug in OJC, the protected access modifier should only be allowed for member classes. I filed a bug report and I'll fix it.
Thanks!

Wuc-15 form must contain the following bean

hi
i am trying to use the client_text_io api's in a form but i keep getting the wuc-15 error (your form must contain the following bean for this function to be available - oracle.forms.webutil.file.FileFunctions). i do have the webutil object group in the form, i added it after attaching the library but i did go back and recompile all the pl/sql code just in case. forms90_path does include webutil/forms.
the only thing that i can see that might be a problem is that because of utf8 issues i have to use the sun jdk. i have the following block in my formsweb.cfg file to force the form to use the sun jdk instead of jinitiator
[jdk_plugin]
basehtmljinitiator=basejpi.htm
basehtmlie=basejpi.htm
baseHTMLjpi=basejpi.htm
jpi_download_page=http://java.sun.com/j2se/1.4.2/download.html
jpi_classid=clsid:CAFEEFAC-0014-0002-0004-ABCDEFFEDCBA
jpi_codebase=http://java.sun.com/products/plugin/autodl/jinstall-142-windows-i586.cab#Version=1,4,2,0
jpi_mimetype=application/x-java-applet;version=1.4.2
i have left it this way since when i change the basehtml entries to use the webutil templates i get thrown back into jinitiator. is this causing the wuc-15 error? if it is how do i use the webutil templates with the sun jdk?
thanks
penny svetlik

the forms90_path variable contains less than 100 characters.
i ran the form with increased trace level but did not get anything additional in the way of errors (just the usual 'unable to attach library' error in the alert box). here is the trace information. by the way why do the findlocalhost and getipaddress calles repeat 8 times?
