javascript is not a type of java. It is a separate language. What do you mean by "making websites". A website in its simplest form is just an HTML page. If you want to learn what's called a "server side web programming language", which will allow you to do things like retrieve data that a user entered into a form on an HTML page and store it in a database, then first you need to learn basic java, and then you need to learn basic HTML(and it would be beneficial to learn basic javascript although that's not mandatory), and then you need to learn "servlets+jsp"--which is the java version of a "server side web programming language". The easiest "server side web programming language" to learn and the one that is most popular is php.
Some books you might consider:
beginning Java: "Java2: A Beginner's Guide"
beginning servlets+jsp: "Murach's Java servlets and JSP(2008 edition)" -- includes an introduction to HTML
Im new in using java applet, threading and stuff like that :).OK. You don't need know applets or threading to learn servlets+jsp.
And maybe I can make management systems in java language is this possible?
Sure.

  • How can i use AME for the new OAF page.

    Dear all,
    I have developed a new OAF page and registered under Employee Self Service.
    How can i use AME for the approval process.
    Appreciate your ideas?
    zamora

    I will try to answer based on my experience of working with iProcurement and AME. It depends on how you want to make a call to AME , directly from OAF Page or from Workflow and your requirement. You didn't specify what you want to show the users on OAF Page and your business requirement.
    Before calling AME Engine from the OAF page or workflow, I guess you did already setup AME Transaction Type and it's Approval Groups, Conditions, Action Types and Rules. Do some testing from AME Business Analyst Test Workbench. Please note that, AME provides lot of PL/SQL API's that you have to call from your programs (java or workflow pl/sql)
    Let's look at the workflow and putting an OAF Page as notification.
    As Sameer said, you have kick-off workflow process from PR of CO and with in the workflow function, you make a call to AME Engine API's with the AME Transaction ID. This transactionId belongs to the AME Transsaction Type that you setup. Based on the rules setup, AME Engine generates list of approvers/approver and stores them AME Tables for that transactionId. Then, it sends a notification to the approver.
    In the workflow, where that notification is defined, in the message body you have to put an attribute(&XX_WF_FWK_RN) of type document/send. And this attribute will have the constant JSP:/OA_HTML/OA.jsp?OAFunc=XX_FUNC&paramId=-&DOCUMENT_ID-. This function is SSWA Jsp function that makes a web html call to your OAF Region.
    If your requirement is to just show the list of approvers on the OAF Page, you may have to call AME API diectly passing your AME TrasnactionId with other parameters. Then AME generates list of approvers and stores them in AME tables with each approver status. You can pickup those approvers using VO and show them on OAF Page.
    Hope this gives some idea.

  • How can we  use java variable in javascript code on JSP page?

    How can we use java variable in javascript code on JSP page?
    Pls help

    Think about it:
    JSP/Java is executed on the Server and produces HTML+JavaScript.
    Then that HTML+JavaScript is transfered to the client. The client now interpretes the HTML+JavaScript.
    Obviously there's no way to access a Java variable directly from JavaScript.
    What you can do, however, is write out some JavaScript that creates a JavaScript variable containing the value of your Java variable.

    Would it be possible for me to download iTunes in Parallels and get the files into that and then onto my iPod?
    Yes, you can download iTunes for Windows using Parallels. If planning on making purchases here and/or authorizing already purchased tracks (from your Mac iTunes library), you are permitted to authorize five (5) computers as per iTunes Store terms of use, regardless of computing platform. No need to create a separate new iTunes Store account.
    However, judging from what you would like to do, your best bet would be to convert the WMAs to AAC/MP3 in iTunes-Windows (iTunes-Mac cannot import WMA files), and drag the files from the Parallels window to your desktop to add to the iTunes-Mac library. (as the iPod itself is currently linked to your iTunes-Mac library)
    Hope this helps,

    It sounds like you are talking about the cloning tool?
    Tool looks like this:
    Then when selected you can change the size of the brush and using Alt (windows) and Command (Mac) to select your region you want to copy then start to create you cloned image.

  • I got an iPhone 4 while I was living in Japan. How can I use it in the states now that I live here?

    I was using an iPhone 4 while I was living in Japan. How can I use it in the states now that I live here? It is a perfectly good phone and I don't want to use it only as an iPod and camera.

    That's one option. The other is to sell it (you can probably get close to what you paid for it) or trade it in and get a new unlocked phone directly from an Apple store. That way you can use it in the US, and also in Japan when you return there.

  • How can i use or embed  the ' C'  language in java

    thanks a lot friends for your suggestion on using 'c' language to implement the control of the keyboard ie. to prevent a key stroke of : ctrl+alt+delete keys from closing a running java application. i was advised that it won't be possible to implement this with java language, the use of 'C' language was suggested. i then wish to ask the following:
    1. how can i use 'C'language in a java program and be able to compile to program so that the resultant program can help me prevent the closing of my java-application when the user of the application presses the following keys : ctrl+alt+delete. i don't even know the c language at all. how can i start and how can i combine the resultant code with java.
    2. i'm thinking of creating an application that retrieves information from a database, like microsoft sql or oracle, and displays the resultant data from a table, say STUDENT TABLE, in a java application using the JTable class. i don't even know how to use this JTable but i've seen it used and know it will suit what i have in mind.
    3. how can i make the table dynamic, ie. how can i make the table to immediately register / show the result of an update to the 'STUDENT' table in the database.
    4. THANKS FOR YOUR HELP IN ADVANCE. i will most appreciate it if you can give me a sample code or a site where i download one. once again thanks.

    Good luck disabling Ctrl+Alt+Del! I've read quite a bit about it, and at least on Windows 2000 (not sure about NT) or higher, disabling it is next to impossible. Problem is CAD is a system command, and the OS doesn't even send the keys to the active program. Ctrl+Alt+Del is handled by the GINA (Graphical Identification and Authentication) DLL installed on the system. You'll have to write and export the functions you need and change the GINA DLL used by the system to your own. Bear in mind that any small mistake in the dll can cause you to lose access to your computer if you haven't taken precautions!
    On Windows 95/98, disabling Ctrl+Alt+Del is fairly easy as you just have to write some simple native code to fool the system that a password protected screensaver is running.
    I've provided a link regarding winlogon and GINA here, but you've been forewarned!

  • How can I use XMLBeans in a Web Services client?

    How can I use XMLBeans in a standalone Java client with a Web Service?
    I posted the message below earlier in the year, but have not yet been successful
    in my
    attempts.
    regards
    Eddie
    Hi,
    I'm trying to using XMLBeans to send a document to a web service from a standalone
    Java client. I'm using the PurchaseOrder (easypo) example document, and the service
    expects a parameter of type PurchaseOrderDocument. The client proxy class generated
    by WebLogic Workshop, however, expects to send a parameter of type PurchaseOrder.
    In the client, I can instantiate a PurchaseOrderDocument, and then obtain a PurchaseOrder
    (e.g. pod.getPurchaseOrder() ), but the returned class is not compatible with
    the PurchaseOrder type that the client proxy expects.
    In a previous attempt (not using Workshop), the client would not compile because
    it expected to send a non-abstract class with a public default constructor (presumably
    a JAX-RPC requirement), and XMLBeans had generated an interface.
    Any help would be greatly appreciated!
    thanks & regards
    Eddie

    I have been experiencing similar problems with the HTML Editor and have managed to find an answer that should start to answer some of my questions. The Apex HTML Editor Standard is actually an HTML editor called FCKeditor. The FCKeditor has a Javascript API that can be found at http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/JavaScript_API. Unfortuately this doesn't seem to give the whole answer and I found more at http://www.houseoffusion.com/groups/cf-talk/thread.cfm/threadid:49607.
    I needed to get the text entered within my html editor standard (e.g. P1_MYTEXT) and use it within my javascript function. I did this by using the following script
    <script language="JavaScript" type="text/javascript">
    function showtext(){
    var oEditor = FCKeditorAPI.GetInstance('P1_MYTEXT');
    var editortext = escape(oEditor.GetXHTML(oEditor.FormatOutput));
    alert(editortext);
    </script>
    Hope this helps.

    Not that I could find.
    The easiest workaround that I could find is a trimmed piece of Black Construction Paper taped over the Mac's display.
    Alternatively, you could use an external Mac Compatible Web Cameras and then close the lid, but that is a higher cost option.

  • How can I use comma in the return values of a static list of values

    Hi all,
    I want to create a select list (static LOV) like the following:
    Display Value / Return Value
    both are "Y" / 'YY'
    one is "Y" / 'YN','NY'
    I write the List of values definition is like this:
    STATIC:both are "Y"; 'YY',one is "Y";'YN', 'NY'
    However, it is explain by htmldb like this:
    Display Value / Return Value
    both are "Y" / 'YY'
    one is "Y" / 'YN'
    / 'NY'
    I tried using "\" before the ",", or using single or double quote, but all these do not work:(
    How can I use a comma in the return values?
    Thanks very much!

    "Better still, why not process the code of both Y with 2Y and one is Y with 1Y? "
    Could you please explain in detail? thanks! I am quite new to htmldb
    In fact I have a table which has too columns "a1" and "a2", both the values of these two columns are "Y" or "N". AndI want to choose the records that both a1 and a2 are "Y", or just one of a1, a2 is "Y".
    So I write the report sql like this:
    "select * from t1 where a1 || a2 in(:MYSELECTLIST) "
    Thus, I need to use "," in the LOV, since expression list in IN(,,,) using ",".
    Any other way to implement this?

    How can i use javabeans in forms?

    You need to Create your JavaBean.
    Then you need to run the "Oracle Forms PJC" Wizard which can be found at File | New .../Beans tab.
    This wizard generates the correct adapters to allow JavaBean properties/events to be propogated to / from the Forms environment.

  • How can I download videos from the web using Firefox?

    I have used Cometbird as my internet browser for almost a year, but a few friends told me that Firefox is better, so I downloaded Firefox to give it a try. Unfortunately, I am experiencing a problem -> I can find no option that allows me to download videos from websites, using Firefox. With Cometbird, when I'm on a website page that offers videos, all I have to do is right click and Cometbird automatically finds any available media and allows me to download it. With Firefox, when I right click, the only viable option is to, "save the page", which doesn't allow playback of the video after saving it. Confused, I went to a Firefox page that explained to me about "add-ons", and, after looking through some of the add-ons available, I downloaded one labeled, "download helper" and followed the tutorial exactly, yet still, I was not able to download any videos. This forces me to ask two questions -> #1) Why would Firefox make available an add-on labeled, "download helper" that doesn't download anything? ....... #2) Why would Firefox not include the option to download videos from websites? ------- The internet was invented for the sole purpose of sharing information; The only way to retrieve this information is to download it; The most popular form of information downloaded is videos; Yet, with Firefox, the ability to perform the most widely used method, of the most popular form of entertainment, is not included with its internet browser. This would be comparable to a grocery store not selling bread, milk or eggs. Please explain.......

    Some videos will allow downloading.
    I use Safari, and when I right-mouse click on some videos, there will be an option to download.

  • (how) can I access Java APIs from web-page-hosted JavaScript?

    Can I access Java APIs from a web-page via JavaScript if I have a JRE installed on the client machine? And if so, how?
    Thanks in advance for your time and consideration.

    John L. wrote:

And if so, how?As far as I can remember that was actually possible in the very first versions of Netscape because Netscape really wanted to pretend Javascript and Java were meant to be used together. But they soon removed that functionality. Can you guess why?
    Because people were using the File/IO classes to easily steal or remove files on the harddrive, among other such niceties. You do NOT want to have such control from a web application. People will abuse it.

  • How can I use java.util.Date and change display format.

    Hello All,
    I want to use java.util.Date in View Context and in Custom Control Context of Web dynpro java. When i mapped of a Input Field to the java.util.Date then message shows that its not supported. Plz suggest me how to handle Date with different formats ??

    If you always want the user to enter the date in dd/MM/yyyy, you can do the following.
    Goto Local Dictonary -> Simple types in your project and create a type known as "InputDate" (or whatever you feel) of built-in type 'Date'.
    Now specifiy its format in the 'Representation' tab as "dd/MM/yyyy" (case-senstive).
    Now declare a value attribute say "inputdate" in your context with this type and bind the inputfield to this context value attribute.
    This will solve your problem.
    But if you want the user to input date depending on the region he belongs, change the default locale date in Control Panel->Regional and Language Options->Change to English(UK) -> Customize -> Date Tab -> Sort Date Format to dd/MM/yyyy.
    Now clear the cache, delete temporary files and restart the machine. This should solve the problem.
