  • Cannot Acccess Applet Object from Java Script

    Hi,
    I am using jRE1.5, and Kava Chart Applets. Those applet jars are compiled in jdk 1.5 version. I have created one jsp where I used ,<applet> tag. The problem is when ever I am going to access the applet object from java script it is not returning the actual java applet object, when put an alert message it shows [object]. So i am not able to access the methods or the applet class.and also the screen gets hung, nothing is coming.It get stuck at the point where i tried to access the applet method like document.getElementById(applet_id).<<<some method of the applet class>>.Also it is not showing any kind of javascript error or Applet class exceptions.
    But the strange thing is, when i use jdk 1.6, the page is running fine.Also when i try to print the applet object from javascript it is showing the proper class name.
    Please help me solving the problem.

    A number of changes and improvements were made between 1.5 and 1.6 - the entire plugin is new. You need to change to 1.6, as 1.5 goes EOL about November this year and future changes to this area in 1.5 are unlikely.

  • How to get the parameter from Java Script into the Parameter crystal Report

    Hi All,
    Crystal Report is integrated with Oracle 10g. I created the base SQL query for col1, col2, col3 and col4. Java Script pass parameter value (185) to Col1.
    My question is how to create crystal report to make Col1 as parameter and how to get the parameter value 185(Col1) from Java Script. Is there any additional code I need to include in the crystal report?
    FYI.
    Java script sends the right parameter value.There is no issue in java script.
    This is an automatic scheduled process when batch runs, Java script should pass the parameter value and the crystal report should get the value and produce the output report.

    Not sure if this is an application question or if you are trying to hook into Crystal Reports parameter UI? If the later then no option other than report design. If an application then I can move this to the Java Forums.
    If you are asking how to alter the parameters I suggest you remove the Java reference and post a new question so it's not confusing the issue.
    Please clarify?

  • I just downloaded and instaled firefox 4. Now, everytime I institute a command I get a po[p-up from Java script that tells me to uninstal set. I cannot go on untin I press ok and then I am good for one more command and it starts with the pop-up again.

    I'm not even sure if this is an extension or plug-in and all I can tell you is what I have already stated. I can only make one command at a time and after each one I get a pop-up from Java script that says uninstal set. I must depress ok to move on, but only for one more command and it starts over again. This also happened when I tried to instal firefox 4 a couple months ago and I deleted the program and went back to an earlier version.

  • Opening ADF page from java script

    I am trying to use window.open(url, winName) to open an ADF page from java script.
    I have set the same winName but when i call the window.open method every time it opens up a new window.
    The code is as below:
    <html>
    <head>
    </head>
    <body>
    <script>
    function openwin() {
    window.open("about:blank", "winDocPrint", "width=800,height=600,location=no");
    </script>

    <input type="submit" value="Print Comments Call ADF">
    </form>
    </body>
    </html>
    when I click the button first time, it opens a new window, and keeps opening a new windows on clicking the button again.
    I want it to use the same window that was opened first time.
    Any help would be appreciated.
    Thanks,

    Hi,
    you need to keep the window handle reference so you can access the same window

  • Flexible graphs from java script

    Hi,
    Can anybody help me to find flexible graphs with java script?. I am using Oracle 9i as my database, jsp and ejbs...
    Thank you.

    Can anybody help me to find flexible graphs with java script?. "Flexible graphs"? If you mean a graphing package in Java, just google for it. Plenty of commercial, shareware and freeware choices available (though some are obviously a lot better than others :-).

  • Combine JSP with Java Script!

    Hi,
    I am writing a .jsp file. I am able to put value of jsp into my java script code like..
    var i = <%= k %>
    but, now my requirement is reverse. I need to put the value of java script variable i into jsp variable k.
    Someone told me that it is possible using eval function.
    Now, using eval function , I can do the following ...
    function xyz() //java script function
    eval(<% int k = 5; %>);
    but, I need to put the value of java script variable i into k.
    I tried eval(<% int k = %> + i);
    but it is not working that way.
    Can anyone tell me how can I achieve this? Please reply as soon as possible.
    Thanks

    Just came across this, and even though it's old, I thought Id add something to it since I know a lot got problems combining javascript and jsp; and that most usually don't provide enough info to get someone started.
    To be able to "use" Java variables inside a javascript, you need to pass them in the function call:
    <%
        String aVariableToPass = "tadaaaaa";
    %>
    <form onSubmit="myFunction(this,'<%=aVariableToPass %>')" method="post" name="myForm" action="">
       <table>
         <tr>
              <td>
                   <input type="submit" value=HitMe" name="submit"/>
              </td>
         </tr>
       </table>
    </form>The function:
    function myFunction(form, theVariablePassedIn)
             var accessToTheVariable = theVariablePassedIn;
    }Now use accessToTheVariable inside the javascript, or theVariablePassedIn directly if you please.
    Cincerely. P

  • Trigger Backing Bean Action from Java script

    Hello
    I'm quite new to JSF, Would like to know how we can trigger a bcaking bean action method using java script as part of form submit.
    Already I added one commandbutton with an action method defined in backing bean, But our requiremnt is to trigger the same action even if the user submits form by pressing Enter key.
    Targeted device is Windows Mobile IE ( In IE Mobile, we can't track onkeydown, onkeyup, onkeypress, onmousemove, onmousedown and onmouseup event. )
    1. How the JSF binds a backing bean method with JSF commandButton control on runtime. I didn't find any hidden value corresponding to this commandButton.

    But one question, just because of curiosity
    1. How the JSF binds a backing bean method with JSF commandButton control on runtime. I didn't find any hidden value/or any other flag corresponding to this commandButton from the genarted html for the correspondant jsf soure.

  • How to trigger a trigger in a Web Forms 6i from Java script

    Hi,
    I have an applicatin that has two frames. One displays a map, the other one the Oracle Forms 6i web forms. I display the datasheet of various map objects in the second frame when the user clicks on a map object in the first frame.
    My problem is that since each Forms has a different link, JInitiator reloads each time, thus making it the form a bit slow to display.
    Any tips? Thanks in advance.

    Hi,
    this kind of inter-region communication requires the use of contextual events in which the producer region sends a notification to the receiving region, which then uses a method to launch the popup. You don't use the showPopupBehavior for this but JavaScript from Java
