Help required in understanding the flow of control in working with EJB 3.0
*1. Can anyone help me in understanding the flow after getting an object of InitialContext in using Stateless/Stateful in EJB 3.0 from client i.e. what we are getting in the step Object ref=jndiContext.lookup("CalculateBean/Remote) .*
*2. What is the use of INITIAL_CONTEXT_FACTORY*
*3. PROVIDER_URL*
*4. Java.naimg.factory.url.pkgs*
*5. why org.jboss.naming and org.jnp.interfaces separated by semi colon.*
*6. Why we dont require INITIAL_CONTEXT_FACTORY, PROVIDER_URL and Java.naming.factory.url.pkgs if the client is a web client.*
Properties p=new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.PROVIDER_URL,"jnp://localhost:1099");
p.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
Context jndiContext = new InitialContext(p);
Object ref = jndiContext.lookup("CalculateBean/Remote");
Calculate c = (Calculate)ref;
int sum=c.add(3,4);
System.out.println(sum);
Thanx in advance........Annotations can also be processed at run time using the core reflection API (java.lang.Class & java.lang.reflect.*), so you might want to explore down that path. I have no idea how JBoss actually does it, but annotation processing at build time and core reflection at runtime are the two most obvious possibilities.

Help required to understand the concepts for data files in tablespace
Hi Guys!
Conceptual understanding for data files.
A tablespace is having 2 datafiles.
What once the data files will get full? I know we can create data files but what if there is no space on the server for any additional file to be created?
Do we require to make the oldest file offline and move outside the environment?

ThanksIf the datafiles are full, there is not much that you would get from the "defragmentation" of the datafiles. It would be sort of like this in the start,
FFFFFFFFFFFFFFFFFFFFFFFFFF
Then it will be ,
FFFFFFFUUUUUFFFFFUUUUUU
So what you are going to get is something like this, (if would be done),
FFFFFFFFFFFFFUUUUUUUUUU
So that's how the datafile would like. But that won't give you much of the space anyways still. The option to add a storage must be there with you. The file being offline wont take away the space that it has already allocated. And moreover, doing so, would also impact the access to the data that it would be storing within it.

Help required to understand the configuration parameteres set in Ora JDBC
Hello Support,
Client is connected through Oracle JDBC and folllowing values is assigned in the configuration.
(FAILOVER=on)(LOAD_BALANCE=off)
I would like to know what is the meaning of above values please ? specially Load_balance = OFF
ThanksI don't know if this will help or not, but with an executable jar file, the classpath is handled differently. All classes are expected to be contained in the jar and external classpath info is ignored. This may also be true in your case if the files are being accessed in that manner. You could try it out quickly by moving the policy and conf files into the jar and dropping the path info.
If that works, you can decide whether or not you want it packaged that way.
If it doesn't work, try unpacking the jar file and running it that way, instead of the executable jar. Again, if that works, you can decide how you want to package your app based on that information. -
Could you please help me understand the logic behind certain things in OSX?
Ok, so I try to be an open-minded guy, and I bear no particular allegiance to either OS. I own a Sony TZ and a Mac mini, and my wife has a MacBook Pro. I use both Oses.
There are certain things I have trouble understanding in th Mac OS, so what I'd really like to understand the logic behind certain design decisions in the OS, and why these might be better ways of accomplishing things. I know how to get around all of the things I mention, so I'm not looking for instructions; rather I'm looking for well-thought out explanations for why these features are the way they are.
*1. Programs don't quit when you close the window.*
- This totally puzzles me. Why design it so that program windows are independent are from the running program itself? There must be a reason, cold someone explain how this is more efficient? To me, it's simpler to click an X on the window you are working on to completely shut down a program, rather than to either mouse through menus to select quit, or be obligated to using Command Q keyboard shortcut.
*2. Menu bars are on the desktop.*
- Related to the first point, why make the main thing framing your desktop be something which is always changing depending on the program? Why have file menus outside the main window of the program. Having the menu bar on the desktop then necessitates an additional area, the dock, which has to be used as a launch bar and to tell you what programs are currently running. That obligates you to having 3 different areas of screen: 1 for program menus, 1 for running programs, and the program window itself. This seems very inefficient to me. Not to mention all the messy-looking floating palettes all over the place, again because everything is separated and not nicely contained in a single program window.
- Really, having a changing menu bar that frames the desktop isn't even consistent wth the whole desktop metaphor, which is that you place things on a desktop, like programs, files, etc. Are you changing the whole desk everytime you load a new program, yet the wallpaper stays the same? Doesn't seem to be logically consistent to me.
*3. No delete key.*
- This one really gets me. Why make such a commonly used key be a function key (Fn + Backspace)? Why make the user press a secondary key for a major function?
*4. No Cut command.*
- I read something about how Cut doesn't actually make sense when moving files around, but I obviously didn't fully understand it. Why make the user command drag, when you can just do Ctrl X??.
*5. Launching Apps from the Finder.*
- This seems weird to me, that you find and launch applications from the same thing you use to view files. Program icons in the finder are placeholders for the entire program, not files, yet they are found in the file viewer. Again, to me this seems logically mixed. I really dislike scrolling through Finder to look for apps. I know there is Spotlight and the dock (used as a quicklauncher), but these are really just workarounds for a setup which seems inherently illogical. To me at least, a menu of applications make more sense, ie, the start menu.
Anyway, those are all I can think of now, although there are other things aout OSX that don't make sense to me.
Thanks in advance! If I can understand Apple's reasoning and it is convincingly better, that will go a long way towards making me more comfortable with this OS.1. Programs don't quit when you close the window.
That's really more a matter of what you're used to. It comes down to a programming decision as to what Apple and Microsoft considered to make sense. MS thinks that if there are no open windows, you're done using the app. Apple thinks you aren't necessarily done yet, as others have mentioned. I certainly wouldn't want Photoshop to quit every time I closed the last open image I was working on. Would be nice though if Safari would quit when I close the last open browser window. It's quick to relaunch if you really weren't done with it, so wouldn't be much of a bother to have it shut down with the last window.
2. Menu bars are on the desktop.
Makes way more sense the Microsoft's approach of repeating the same file menu on every open document in a program. How many places do you need to see File, Options and other common menu headings?
2. Menu bars are on the desktop.
Related to number two. The forward app is the only one you can directly work in, so why not have the menu bar change to reflect the choices for that application? When you go back to the previous app you were in, the menu bar changes back. So what loss of functionality is there? It comes back to not having menu bars on every single open window. There's no need or purpose for it.
3. No delete key.
Backspace does the same thing.
4. No Cut command.
Command+X, not Ctrl+X. This is Mac, not Windows. There's also very little need to ever do this from the keyboard. If you're moving files that are on the same drive/partition, then just drag and drop from the target folder window to the source. It's automatically a move. If going from one physical drive or partition to another, it's automatically a copy. Press and hold the Command key during the drag to make it a move.
Besides, you don't really think Windows cuts the entire folder or file contents into RAM, do you? If your computer has 4 GB of RAM, and you cut 12 GB of data, it of course can't possibly fit in the clipboard. All Windows does when you do a cut is visually remove the files and folders from the screen. If the items are going to a location on the same drive/partition, it does the same thing as if you did a drag and drop move. The file table is simply updated to reflect the new file or folder locations. If it's to a different drive/partition, it then performs a copy then delete action, same as OS X.
5. Launching Apps from the Finder.
A program is just as much a file as any other file. It takes up space on the drive. The OS of course knows what to do with it when you double click an app. Same as it knows what to do when you double click a document related to an app. Windows is no different. An .exe file is also just as much a file as a .doc file. The .exe extension tells Windows to try and treat it as a program to load into RAM. It's not just a simple placeholder. The program has to be made up of something. -
Help required in understanding of static blocks in java
Hi ,
Can some one help me in understanding the difference between static blocks in java....also what is the difference in declaring some static variables in a class and and declaring some variables in a static block? From an architecture viewpoint when should one use static blocks in Java?Static blocks are piece of code that can beexecuted
before creating an instance of a class.static blocks are executed once, when the class
itself is loaded by the JVM. They are not executed
before creating each instance of a class.
For example whatever you include in the mainn method will be
executed without you having to create the instanceof
the class using the new operator. So you can saythe
main method is a static block.main is not a static initialisation block but a
static method. a special case static method at that -
it is only executed when the containing class is
specified as a parameter to the JVM. (unless you
specifcally call it elsewhere in code - but that
would be bad form).
in answer to the original post, static variables
belong to the class. each instance of the class share
the same static variables. Public static vars can be
accessed by prefixing them with the class name. A
static initialisation block can be used to
initialise static variables. Variables declared
within the static initialisation block exist only
within the scope of the block.
e.g.
public class Foo {
static Bar bar; // static member variable
// static initialisation block
static {
// variable declared in static block...
String barInfo =
arInfo = System.getParameter("barInfo");
// ... used to initialise the static var
bar = new Bar(barInfo);
So is the only purpose of static initialization blocks is to initialize static variables? Does the initialization of static variables inside a static block make any difference in performance? If yes , then how ? -

What is the rationale behind the "Adobe Standard" color calibration profile?
Hi! I'm trying to figure out how to make the most of the various color calibration profiles Adobe offers for my cameras with Lightroom 5. I do understand the purpose of the camera-specific options--they're designed to help approach camera JPEG processing mode colors. And they work wonderfully--they're very helpful!
But I don't really understand the purpose of the "Adobe Standard" calibration option. What is it for? Why does it look the way it looks? Has it been designed to ease certain processing goals? To enhance certain colors or tonal combinations? Is it designed to be more accurate than the manufacturer profiles in some way? What can I do with "Adobe Standard" that I can't do with one of the camera-specific calibration options?
I would find it *extremely* helpful if someone who's involved with the engineering behind Lightroom's color (or anyone else who's especially knowledgeable about Lightroom's design) might talk a little bit about why "Adobe Standard" looks the way it looks. What's it for? To what purposes can I leverage it?
Thanks so much!MarkJoseph wrote:

Adobe Stadnard is the name for the individual profiles Adobe builds for each camera it receives. A new camera ships, Adobe gets their hands on one and builds a profile with that sample. It isn't suppose to mimic the in-camera JPEG settings, I don't believe it's supposed to mimic anything but instead produce what is (and quotes are super important in this context) the most 'accurate' color response from the target they use to create the profile. But here's the rub. Not all cameras from the same make and model behave identically. Adobe simply can't get piles of the same body and build then average that response. So they provide a means for you to build your own custom DNG camera profile and for differing illuminates. So if you want to leverage it, you'd get a target (MacBeth 24 patch, X-rite Passport) and build your own custom profile. It can really help depending on how your sensor deviates from the sensor Adobe got to build their profiles.

gets executed, its calling some other class. Not sure what is being called, but i can see the log messages that its executing some other class which actually does the calls to DB APIs and inserting data into main tables.
Can you please explain me what is being called to make DB API calls. I would greatly appreciate your help.
Thanks in Advance!

As soon as the transaction is commited the methods in the VORowImpl Class are called.
You can check in the VORowImpl class and search for the log messages.

Help Required in Migrating the Dev to Test Instance
Hi
Am very new to SOA platform, i developed one project in dev instance. now i would like to move this project to test instance.
can any one help me to migrating the project.
So I Need sample document with step by step instruction. i have 5 days only to migrate, i gone through so many blogs and post in metalink, but i didn't understand the concept exactly.
Santhosh Kumar. KHi K,
There are many ways to do it, it will all depend on your environment.
The way that works for me is:
1. Deploy your project to SAR (it will actually generate a jar file)
2. Copy the generated file to the environment where it will be deployed
3. Use the ant-sca-deploy.xml to deploy it
ant-sca-deploy.xml will be located at $BEA_HOME/Oracle_SOA1/bin
and you can call it from your own ant build.xml like this:
<target name="deploy-app">
<ant
antfile="${beaHome}/Oracle_SOA1/bin/ant-sca-deploy.xml"
target="deploy"
dir="${beaHome}/Oracle_SOA1/bin"
>
<property name="serverURL" value="${scaDeployUrl}"/>
<property name="sarLocation" value="${appEarDestDir}/${sca.jar}"/>
<property name="overwrite" value="true"/>
<property name="user" value="${domainUser}"/>
<property name="password" value="${domainPwd}"/>
<property name="failOnError" value="true"/>
<property name="partition" value="${partition}"/>
</ant>
</target>

Help required in implementing the algorithm
Actually I am brand new to the java programming, and i need some help to implement the algorithm below in java.
I have the dataset required for the execution,
Can any body please help me?
Input: (1) a source database D,
(2) a min support,
(3) a min confidence,
(4) a set of recommended items Y
Output: a transformed database D, where rules containing
Y on RHS will be hidden
1. Find large 1-item sets from D;
2. For each hidden item y �� Y
3. If y is not a large 1-itemset, then Y := Y − {y};
4. If Y is empty, then EXIT;// no AR contains Y in RHS
5. Find large 2-itemsets containing items in Y from D;
6. For each y �� Y {
7. For each large 2-itemset containing y {
8. Compute confidence of rule U, where U is a rule likex �� y;
9. If confidence(U) �� min conf, then { //Calculate # of transactions required to lower the confidence of U
10. Calculate iterNumConf = _|D|∗(supp(xy) − minconf ∗supp(x))_;
//Calculate # of transactions required to lower the support of U
11. Calcualte iterNumSupp = _|D|∗(supp(xy)− min supp)_;
12. Calculate k = minimum (iterNumConf, iterNumSupp);
13. Calculate |TR| = |xy|; //|TR|: # of transactions inTR
14. if k > |TR|
15. Can not hide U;
16. else {
17. Find T kR = first k transactions that contain xy;
18. Sort T kR in ascending order by the number of items;
19. for i = 1 to iterNum do { 20. Choose the first transaction t from T kR ;
21. Modify t so that y is not supported, the RHS(U);
22. |xy| = |xy| − 1; // update support count of xy
23. confidence(U) = |xy|/|x|; // update confidence
24. Remove and save the first transaction t from T kR ;
25. }; // end for iterNum
26. }; // end if confidence(U)
27. }; // end of each large 2-itemset
28. Remove y from Y;
29. } // end of for each y
30. Output updated D, as the transformed D;The way you post that, it looks very much like "Do my work for me". Nobody around here likes that kind of post, they consider it lazy and selfish. But perhaps you didn't mean it that way? Why don't you explain what you have done and what parts of it you are having problems with. Explain those problems in detail.

Help needed in understanding the Java code.
Hi All,
I have recently started learning the Java language. I came across this example and had a problem in understanding the output of the program. I could follow that if the continue statement is present in the below program the output is "Found 9 p's in the string" . But if the continue statement is removed I could not understand why the output would be "Found 35 p's in the string" .Is it because of the spaces and characters other than p... (eter ier icked a eck of ickled eers)
Example-----------------------
The continue statement skips the current iteration of a for, while , or do-while loop. The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop. The following program, ContinueDemo , steps through a String, counting the occurences of the letter "p". If the current character is not a p, the continue statement skips the rest of the loop and proceeds to the next character. If it is a "p", the program increments the letter count.
class ContinueDemo {
public static void main(String[] args) {
String searchMe
= "peter piper picked a " +
"peck of pickled peppers";
int max = searchMe.length();
int numPs = 0;
for (int i = 0; i < max; i++) {
// interested only in p's
if (searchMe.charAt(i) != 'p')
continue;
// process p's
numPs++;
System.out.println("Found " +
numPs + " p's in the string.");
Here is the output of this program:
Found 9 p's in the string.
To see this effect more clearly, try removing the continue statement and recompiling. When you run the program again, the count will be wrong, saying that it found 35 p's instead of 9.The answer is already in your example - "The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop."
It unloads the current loop iteration when condition is matching. Loop is again starting from boolean expression inside loop declaration.

Help required in understanding when to use encodeChildren() method
I am new to Java Server Faces. I am a little bit confused in understanding the uselfulness of encodeChildren() method in renderers? Can any one explain how a datatable component gets rendered?how is it that that row by row processing takes place?
TableRenderer.encodeChildren() is something you can easily imagine:while(there is the next row) {
UIData.setRowIndex(++rowIndex);
write("<tr>");
while(there is the next column) {
write("<td>");
while(there is the next component in the column) {
nextComponent.encodeBegin();
nextComponent.encodeChildren();
nextComponent.encodeEnd();
write("</td>");

Please help me in understanding the following code.
public static void main(String args[]){
int x=0,c=0;
for(int i=0;i<3;i++)
x = x + x++;
System.out.println(x);
why this program always prints zero(0) as output. I am not able to understand the execution sequence of it.bkyadav wrote:

(x++) should be treated as x = x+1; but that is not happening.Here's the rule : you have to proceed the expression from left to right.
For example :
int x = 8;
x = x + ++x; // x = 8 + 9 = 17
int x = 8;
x = x + x++; // x = 8 + 8 = 16
int x = 8;
x = x + --x; // x = 8 + 7 = 15Also, in the for statement of your example :
for(int i=0;i<3;i++)the value of i+ is first tested before being incremented for the next iteration otherwise the test on value of i+ = 0 would have been skipped.
