Confusion over J2SE and J2SE SDK

Hi,
I understand that J2SE (Java2 Platform, Standard Edition) is an abstract specification from Sun and J2SE SDK is Sun's implementation of J2SE platform.
If Sun is releasing a new version of their J2SE platform, what are the things from the below list that can be changed and how.
1. The Java Virtual Machine Specification
2. Java API
3. The Java Language Specification
For example, I notice that for every new release, only the API version is changed where as the The Java Languge and JVM specifications remained the same since very long. Let us say that a new keyword is added, shouldn't the JVM spec and the Java Language Spec change??
Where can I get the release notes of J2SE (not J2SE SDK)?
Thanks,
Suresh

Confused over photostream and I cloud, how to move my pictures

Hi,
I have an iPhone 4S and an iPad 2. Apple store sold me cloud storage over a year ago as my phone needed to be replaced under warranty and I had to back up. I paid to continue after the year was up.
I am horribly confused however as I apparently have 15GB storage I have paid for with 10.6GB available and yet I cannot change to iOS 7 as there isn't enough memory in my phone.
I have synced to iTunes and can't get to my photos which are in photo-stream. Ideally I would like to take all of my photos in photostream and save them onto my PC but I don't know where they are in order to do this.
Any help much appreciated as I'm about to throw the lot out of the window having read what feels like the entire apple support community and getting more and more confused.
Many thanks
Lisa

As I think you have realised, you need space on your phone for the update.

Confusion over user and schema

hi all i am new to oracle
as far as my understanding goes in oracle for every user by default an schema
is created where tables and other objects are granted to the user please correct me if i am wrong
now my problem is that i created user but its not getting reflected in the schema
shouldnt the schema get created automatically
i am confused what should i check for
thanks in advance

hello,
First of all you should know the terminology.
Schema -> Collection of objects (Tables, Views, Indexes, Sequences etc.,)
Example: Scott/tiger (Is a sample oracle user) In database terminology it is named as Scott's Schema.
When you create a new user in oracle the user would be empty with no objects. Unless you have previleges to create objects.

Confusion over script and how to make video play

Hi folks,
I have created a SWF file that includes video, audio and
text. All three parts work fine when I play the SWF file, although
I would like to know what code I should put to be able to stop the
audio from playing.
But my main problem is once I have the SWF file uploaded to
my site. The audio and text part works fine, but the video of a
robot comedy performance will not play. I am not sure why this is,
but when I uploaded the file to Dreamweaver there was a Script file
called AC_RunActiveContent.js that automatically downloaded along
with a file called .htaccess. I uploaded both these files too, but
the video part of the SWF file still would not play. I have tried
the SWF file in Mozilla, IE7 and Flock, but no luck. I also tried
pasting the AC_RunActiveContent.js into my Dreamweaver page and
uploaded that, but that did not work either. I just got all the
code showing. For those who want to see the SWF file for themselves
the link is
http://www.marykingmedia.com/manga2/index.htm
For those curious about the AC_RunActiveContent.js code, I
will paste below. I am not sure if this is Actionscript or not. If
it is, I do not know which Actionscript it is.
But I have absolutely no idea what the problem is, or what I
am supposed to do here. I would be grateful for any help you can
give me. Keep explanation as simple as you can because I am not
terribly tech savvy.
Thanking you all.
Mary
p.s./ I am using Dreamweaver CS3, if that means anything

If you're playing the video from Videos and TV application then it should work.
640K Should be enough for everybody

J2EE SDK and J2SE SDK

Considering only the development tools & APIs from J2SE SDK (taking out the JRE), are those components (java, security, JPDA, etc) also part of the J2EE SDK?

How can I go about using java.util.regex? Can/Would
this regex
support be packaged into some extended javax packages
for JDK 1.3?No, the jre/jdk license prohibit taking its parts alone.
If I use J2SE SDK 1.4 and download all javax packges
that are
in J2EE but not J2SE, and compile my application,
wouldn't it end up with
run-time exceptions...?Hm..dunno.
Take a look at http://jregex.sourceforge.net

Difference between, jre, jdk, sdk and j2se

Dear Sir/Madam,
I want to do some java and j2ee development and run these applications in a java application server environment. Can anyone give me some advices on what should i need to download? Moreover, what is the difference between, jre, jdk, sdk and j2se? Should i need to download all of jre, jdk, sdk and j2se?
thanks and regards,
david

JRE is the 'java runtime environment'. It is responsible for creating a Java Virtual Machine to execute Java class files (e.g., run Java programs)
JDK is the 'java development kit'. It is the same as the 'SDK' (at least in my mind). It normally comes bundled with a JRE and also allows you to compile Java source files into Java class files. The JDK allows you to both write and run programs.
J2SE is "Java 2 Standard Edition". It can refer to either a JDK or JRE. This is 'core' Java. There is also J2EE "Java 2 Enterprise Edition" which allows you to write middleware or server code more easily.
Your final choice will be which version. If you want the current, most common implementation:
J2SE 1.4.2, J2EE 1.3
If you want to skip ahead to the next generation, the latest releases would be:
J2SE 1.5 (also called J2SE 5.0) and J2EE 1.4

System error after installing 10.4.6 Update and J2SE 5.0 Release 4

Hi,
I just installed OS X 10.4.6 update and J2SE 5.o Release 4 and the system doesn't start any more. I get a black screen which says:
[date] [my computer name] getty:/dev/console: Operation not supported by device
Any suggestions?
I will try to start from CD (when I am home later), but first I need to eject the DVD, which is still in the drive. How to do this when the system does not start?
Thanks,
Ulrike

Hi Ulrike,
I will try to start from CD (when I am home later),
but first I need to eject the DVD, which is still in
the drive. How to do this when the system does not
start?
All CD/DVD drives that come installed in a Mac should allow you to eject the CD/DVD tray. Check your owner's manual--the instructions on how to eject the tray are usually given there. For example, on some PowerBook models you had to gently insert a paper clip into one side of the loading slot and push. On the DVD drive in my PowerMac there is a small hole through which I can instert a paper clip.
As for what is causing your problems, I don't know. From what I've gathered, however, installing the combo update (~140 megs) is more reliable than the incremental one (~60 megs). Booting from an external drive helps, too. You might try that.

Difference between J2SE and J2EE...

Hi all. I was wondering what the difference between J2SE and J2EE were. I mean in the code structure. Are the packages the same, like Swing, IO, things like that. I'm a bit of a beginner in Java, only been messing around with it for about 6 months now kind of in my spare time, and I know I'm in now way ready for J2EE, but it's something I think I'd like to maybe look into. I know it's for Enterprise Applications, much bigger scale than I'm used to, but fundamentally, how is it different? Different coding conventions? New packages not in J2SE? I hope what I want is coming across okay. Thanks for all the input.
James

J2EE defines a large number of specifications, in addition to J2SE. Examples are the Servlet, JSP, JMS, and EJB specifications. Most of those specifications are designed to have implementations running inside an Application Server. There are free implementations available such as JBoss (combined with for example Tomcat), and I think youre best bet to learn is to download one of those and go from there. Servlets and JSP are a good beginning, and then maybe move on to EJB and the rest.

JSP with J2SE and J2EE

I am learning JSP from a book that is a year old. Can you tell me if the JSP for J2EE is different from that for J2SE ?

J2SE stands for Java2 Standard Edition which is supposed to define Java standards (and API) to run day-to-day application (single user applications).
J2EE on other hand is Java2 Enterprise Edition. Its supposed to define standards (and API) to be used to create server application that service multiple clients.
One does not succeed the other, rather they target diffenet segments and are complementary. J2EE is more of extension of J2SE capabilities (A J2EE application will requires API defined in J2SE packages).
JSP is part of the J2EE specification (other part being Servlets, EJB, JavaMail, JMS etc) and its supposed to have nothing to do with J2SE excepct using the latter's API in its implementation.
What others have been trying to tell you is that JSP is part of J2EE specification but you need not know the other components of the specification to use JSP.

J2SE and J2EE

what are the differences of J2SE and J2EE in terms of programming? I have used J2SE in developing java applets and standalone applications and now, I want to explore more with J2EE. I am reading articles and site regarding J2EE. But for you what is J2EE all about?.
Thanks!

To be frank, if you have to ask you don't need it. Learn most of what Java SE has and can do; then you'll have a sufficient knowledge base to understand and use Java EE as it's intended, on enterprise-level applications.
If you want more information read the documentation, as I don't care to digest it for you.

J2SE and J2EE Which with what ?

I am running Windows NT 4.0 server, with SP6a & Windows NT 4.0 work station, with SP6a. On reading the various combinations of J2Se and J2EE, which do I need to match. Also I am using ant 1.5.3 and looking at some CORBA 3 work using JacORB 1.4.1. I have been using J2SDK 1.4.1_02 for general jave work.
From what I have been reading it looks as if I need J2SE 1.3.1_02 with J2EE 1.3.1.
What is the real combinations of J2SE and J2EE needed for such a asystem ?
Also at present I do not particularly wish to move to a Win2000 Server/workstation combintion as yet.
Thanks
Omegaall

You may now download J2EE 1.4 which will be compatible with your existing installation of J2SE 1.4.1_02.
However, J2EE consists of the application server and additional tools. They are not required, nor are they recommended for heavy duty enterprise work; J2EE is simply a basic "reference" platform for you to get your feet wet on.
Other alternatives do exist, and if you've tracked down Ant, you probably already know about Tomcat, JBoss, WebSphere and a number of commercial engines. All of these packages essentially take J2EE and extend them further (or are faster, or are more reliable, etc etc).
If you have been asked to develop COBRA objects - as opposed to, and I stress this, as opposed to - merely being interested in the technology, then I strongly strongly strongly suggest you find out what your customer is using and set up a scheme similar to theirs. By developing to the same platform, you can save yourself a lot of deployment and packaging headaches, and essentially develop the objects "the right way" for that system.

JDK1.5.0 and J2SE 5.0

Hi Friends,
I'm trying to download jdk from sun website...I got a doubt like is JDK1.5.0 and J2SE both are same...if not...wht is the difference....
thanks
keshav

JDK (Java Developpment Kit) is the old name.
J2SE (Java2 Standard Edition) is the new name for standard JDK (versus J2EE, Java2 Enterprise Edition)
So JDK1.5.0 == J2SE 1.5.0 == J2SE 5.0 (for marketing concerns, Sun crunched the "1." before the "5". "1.5.0" is developpers language, "5.0" is end-user langauge)

Confused between JDK and SDK

Hello, everyone,
I am really confused about JDK and SDK. I have tried to find something online which can make it clear. But unfortunately, I am still confused on their relationship? It seems that they are the same thing?
Thank you for any help.

Hi there,
If I'm not mistaken, JDK no longer exists.It used to be the same thing as JSDK nowadays. It's just a matter of names, and shouldn't worry you.
See you !

Differences between GUI in j2se and cdc+pp

hello guys and girls,
is there many differences between the GUI in j2se and cdc+pp? I only know that cdc+pp does not support swing. anyone who has such experience in my question, please give me a hand. thanks!

Hi,
What I know about it is that PP implements j2se 1.3 AWT components, and, as for all classes, without deprecated methods.
There is not too much secret about it. I work on a project for Pocket PCs and all the screens I've designed on NetBeans, with it's Form Editor, and then copied and paste the generated code into my project, which I develop using Websphsere Studio Device Developer.
Unfortunately NetBeans Mobility Pack doesn't implement CDC/PP, only CLDC/MIDP.
I hope it can help you a little.

Still confused over fup changes to Total BB option...

There still seems to be confusion over the planned changes for Total BB Option 1 customers.
Although KerryG has informed us that the monthly allowance will remain at 10Gb and the charge for additional use will be changing to £5 per 5Gb, BT customer services seem to think the extra usage charge remains the same as it is now.
Please see posts from KerryG and bobm here -
http://community.bt.com/t5/BB-in-Home/WHERE-IS-OUR-USAGE-MONITOR-BT/m-p/41085#M24680
Does anyone have any further info please ?

Hi Del
I can confirm that the info I provided on the earlier thread was correct. I am sorry if people have received other information when calling in. I have fed this back to the relevant teams to make sure all advisors are aware of these recent changes.
To clarify, the position for BT Total Broadband Option 1 is:
Usage allowance – will remain at 10GB
Additional usage charges – they will be charged at 5GB for £5 (rather than 1GB for £1) as from November 1st 2010.
As mentioned before, there are a couple of links that may be useful for those who think they may be likely to incur additional usage charges and wish to review which broadband option is best for them:
Details of usage allowances for each option
Details of options for upgrading your broadband package
Thx
