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

    Perhaps you should look at the documentation which comes with JDK 1.4.2_08.
    It has the bugs fixed listed.

  • JRE, JDK, SDK, IDE, J2????

    What is the disctinction between all these acronyms and when would they come in handy?
    JRE
    JDK
    SDK
    IDE
    Java2 versus JDK1.4 (what's the difference)

    JRE = Java Runtime Environment. Let's you run java apps/applets by interpreting the compiled java code supplied to you.
    JDK/SDK = Java Development Kit/Software Development Kit = One in the same...has both the JRE and tools (compiler, etc) to actually compile your own java code.
    IDE = Integrated Development Environment - Usually consists of an editor, project manager, graphical development tools to speed up development of code. This is not necessarily java - there are IDE's for C/C++, etc....
    Java2 - Post java 1.1 version of java ... components usually start with a J...like JPanel, JButton, JList. A layer built over the original AWT (abstract window toolkit) that was java 1.1. Java 2 is not supported by most browsers by default without the plugin (the JRE)...Netscape 6 has it tho it's buggy.
    JDK 1.4 is the latest version of Java2.

  • Differences between CTI OS Server and CTI Server ?

    Hello community,
    I've been working with CTI Desktop for a while but I'm not clear about the differences between CTI OS Server and CTI Server?
    If you go to http://docwiki.cisco.com/wiki/Unified_CCE_Software_Compatibility_Matrix_for_8.5(x) and read note 10, they make diffrences between both products.
    Thanks in advance,
    Alejandro

    CTI Server was the original CTI interface into ICM.  It uses a network communication protocol, GED-188 I believe, for communication between the client and server.  This is relatively difficult to program against.  CTIOS and it's related SDKs were developed to provide an easier method of developing desktops and integrating desktop applications.  CTI Server communicates with ICM, CTIOS Server communicates with CTI Server, and desktop applications using the various SDKs communicate with CTIOS Server.  Cisco may be looking to get away from CTIOS Server in the future because of their decision to integrate Finesse with CTI Server rather than CTIOS Server.  Hope that helps.

  • Difference between Wsus 3.0 and Wsus 4.0

    Hi all,
    I would like to know what are differences between Wsus 3.0 and Wsus 4.0.
    I have already notice that for Local Publishing, the method IPublisher.PublishPackage(sourcePath,
    additionalSourcePath, packageDirectoryName), totally ignore the "additionalSourcePath" parameter.
    Are there any documentation or web site where I can find differences between Wsus 3.0 and 4.0 ?
    Thanks.

    I would like to know what are differences between Wsus 3.0 and Wsus 4.0.
    The differences between WSUS v3 and WSUS v6 (please note the correct version number) are documented ... somewhere ... but at the moment I can't find them. (Presumably it would be in the Release Notes for Win2012, but that idea is a bust.)
    In short, these are the notable distinctions:
    WSUS v6 is compiled with the .NET Framework v4
    WSUS v6 provides an extended interface for management via PowerShell
    WSUS v6 supports SHA256 hashes (which were implemented by the WUAgent v7.8 and rolled back to the WUAgent v7.6 in KB2720211 and WSUS v3.2 in KB2734608)
    I have already notice that for Local Publishing, the method IPublisher.PublishPackage(sourcePath, additionalSourcePath, packageDirectoryName), totally ignore the "additionalSourcePath" parameter.
    Changes to the API should be reflected in the
    SDK.
    Also worth of note.. publishing TO a WSUS v6 server must be performed from a Windows Server 2012 system or a Windows 8 system with RSAT. Publishing to a WSUS v6 server from a WSUS v3.2 console cannot be done due to internal dependencies in the Local
    Publishing API on the build number of the console and server involved in the publishing process.

  • Difference between Web Service Developer and Web Compononent Developer?

    What's the difference between Web services Developer and Web Component Developer? What's their job description. I'm aiming to be a web application developer. Which track should I follow?

    Here is another article on J2SE vs JEE:
    http://www.velocityrevies.com/forums/t151124-what-is-j2se-vs-j2ee.html
    I believe the people who said JSE is only for desktop development are not correct, as well as their saying their are 2 kinds of developer (web service and component).
    As I understand it, web service developers provide a way to expose the data and functionality of a program written in a particular language (such as Java or C#) as XML documents to anyone subscribing to the service over the internet. The remote applications subscribing to the service therefore can be written in any other language. For example, imagine a Cobol program trying to get data from a program written in Java. Since both cobol and Java should have ways to parse XML documents, they don't have to know each other's syntax. There are many programs written in many many languages in the web and XML is a standard way for them to communicate. Web Services are an advanced topic and you shouldn't worry about it until you master web applications and/or desktop applications.
    As I understand it, a web component developer creates java widgets that produce some visual image with basic functionality associated with it. For example, an html button. These widgets are used by other developers for the presentation layer when creating a web application or desktop application. I'm not sure about this definition since I never messed with web component development. I suggest you keep way from this specialized area on concentrate on web applications and/or desktop applications.
    You can consider application development as devided into two general categories. Web development and Desktop development (there are others). Web development is further broken down into browser based applications and mobile device applications. I suspect their are more jobs in web development than desktop development. I therefore suggest you concentrate on browder based web development (just my opinion). However, each has their advantages and disadvantages over each other, depending on the task at hand(http://stackoverflow.com/questions/905365/desktop-development-versus-web-development)

  • The difference between AIR-ANT5135D-R and AIR-ANT5135DB-R

    Hi,
    Anyone know what is the difference between AIR-ANT5135D-R and  AIR-ANT5135DB-R ?
    From the dynamic configuration tools for 1252 and 1242, AIR-ANT2422DB-R is inside one of the antenna option.
    However, I can't find it in the "Cisco Aironet Antennas and Accessories Reference  Guide"
    http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.html
    Inside the document there is only AIR-ANT5135D-R.
    likewise for the 2.4 GHz,  AIR-ANT2422DB-R is inside the dynamic configuration tools and not inside "Cisco Aironet Antennas and Accessories Reference  Guide"
    Any help would be appreciated
    Thanks,

    Found the difference, AIR-ANT5135DB-R and       AIR-ANT2422DB-R are  non-articulating antennas.

  • The difference between Telepresence Content Server and MSE 3500

    Good day! Could someone explain me what's the difference between Telepresence Content Server and MSE 3500? Why do I need to obtain two these devices for sorting out my tasks? I want to understand gist of the first and the second devices.

    In addition to what Jonathan posted above, here is a Capture Transform Share Solution Guide that goes over a little bit of what the TCS and MXE are and some possible deployment scenarios.
    In short, TCS is used to record video conferences or lectures that can be streamed on demand or live using various streaming or distribution methods.  One such distribution method is using the MXE 3500 to ingest the recordings from TCS and convert them to different media types and add in-video content such as logos etc.  However, from the MXE, you can't send the video back to the TCS for viewing, you'd need to send that off to another viewing portal such as Show and Share.

  • What is difference between  Service map iview and Workset Map iview

    Hi Experts,
                        Can anyone tell me the difference between  service map iView and Workset Map iView.
    When I am creating these iViews, its seams both are same. I canu2019t find difference still, can anyone help me out of this
    Thanks in Advance
    Janardhan

    Hi,
    Service Map Iview:The Service Map iView is an ERP-specific variant of the portal Workset Map iView. It serves as a central point of entry and guided access to the services of SAP service modules such as the Manager Self Service (MSS) module, or the Employee Self Service (ESS) module.
    Workset Map iview:A Workset Map is the equivalent of a site map, providing users with explicit information on the functionality that is available in a given workset. It is based on an iView, and serves as a central point of entry and guided access to the contents of a workset.
    if you want to more info pls go thr the below thread
    Workset Map iView
    i hope it will help you
    Thanks,

  • What is difference between ADF Task Flow and Faces-Config - when delpoy ?

    What is difference between ADF Task Flow and Faces-Config? When I create navigation between pages with ADF task flow then the navigation don't work when I deploy my application to Weblogic 10.3. When I use default server then navigation works fine. With Faces_config in both situations all works ok - on Stanalone server and default.
    Where is the problem?
    Best regards!

    Shay, I don't use both faces-config and adf task flow! When I failed with task flow I tried faces-config.
    I have active on my weblogic - adf.oracle.domain(1.0,11.1.1.0.0). This is the right ADF? If yes then where is the problem?
    Best regards!

  • What's the difference between a web site and a web application?

    I'm stumped trying to come up to a difference between a web site and a web application for myself. As I see it, a web site points to a specific page and a web application is more of some sort of 'portal' to content and information.
    But where I'm stuck is that a web application is still viewed through a browser (is it not?) and a web site can still view content dynamically, making the line between web site and application prety gray.
    For instance, does a web site using ASP.NET or AJAX (I assume ASP.NET is AJAX's proprietary sibling, if not, ignore ASP.NET AND concentrate on the AJAX), becomes a web application because it can retrieve data dynamically and asynchronously or would a website
    using PHP and a CMS be more of a web application because it forms the pages on request, based on the request of the client and its content in its databse?
    Or maybe I'm totally wrong here - what differenciates between a web application and a website?

    This is totally personal and subjective, but I'd say that a website is defined by its content, while a webapplication is
    defined by its interaction with the user. That is, a website can plausibly consist of a static content repository that's dealt out to all visitors, while a web application depends on interaction and requires programmatic user input and data processing.
    For example, a news site would be a "website", but a spreadsheet or a collaborative calendar would be web "applications". The news site shows essentially the same information to all visitors, while the calendar processes individual data.
    Practically, most websites with quickly changing content will also rely on a sophisticated programmatic (and/or database) backend, but at least in principle they're only defined by their output. The web application on the other hand is essentially a program that
    runs remotely, and it depends fundamentally on a processing and a data storage backend.

    There is no real "difference". Web site is a more anachronistic term that exists from the early days of
    the internet where the notion of a dynamic application that can respond to user input was much more limited and much less common. Commercial websites started out largely as interactive brochures (with the notable exception of hotel/airline reservation sites).
    Over time their functionality (and the supporting technologies) became more and more responsive and the line between an application that you install on your computer and one that exists in the cloud became more and more blurred.
    If you're just looking to express yourself clearly when speaking about what you're building, I would continue to describe something that is an interactive brochure or business card as a "web site" and something that actually *does something that feels
    more like an application as a web app.
    The most basic distinction would be if a website has a supporting database that stores user data and modifies what the user sees based on some user specified criteria, then it's probably an app of some sort (although I would be reluctant to describe Amazon.com
    as a web app, even though it has a lot of very user-specific functionality). If, on the other hand, it is mostly static .html files that link to one another, I would call that a web site.
    Most often, these days, a web app will have a large portion of its functionality written in something that runs on the client (doing much of the processing in either javascript or actionscript, depending on how its implemented) and reaches back through some
    http process to the server for supporting data. The user doesn't move from page to page as much and experiences whatever they're going to experience on a single "page" that creates the app experience for them.
