  • Open web browser from java application to specific page

    Hi,
    I used the code from http://www.javaworld.com/javaworld/javatips/jw-javatip66.html to open a web browser to a specific URL. That worked great! However, I run into a problem if the URL targets a specific page, for example, "http://www.yahoo.com/news.html" would give me an problem with the shortcut problem. Any ideas how to get around that?
    The command rundll32 url.dll,FileProtocolHandler http://www.yahoo.com/news/ would work fine, except anything ends with .htm or .html.
    Thanks,
    David

    It looks like url.dll doesnt like .htm or .html files. For more info look here: http://www.jsiinc.com/SUBI/tip4100/rh4162.htm
    For some reason it is confused by the 'm' character in .html which is odd considering it has no problems with .com
    So if you want to keep using url.dll, do something like this:
    replace ".htm" with ".ht%6D"

  • Opening a URL from an application

    Hi everyone, am not quiet skilled with java but i would really appreciate your help with this, as i couldn't find a solution which made me doubt my whole basic knowledge of java. Now am doing this for my school project, it's a speech recognition application that will convert speech to text, there are 2 buttons in my interface, one "start" where you start speaking , the other one "stop" which would allow the engine to start processing the speech and converts it to text, it will then open a web page which in my case is a search engine(say google or yahoo) and searches for the matching documents of what has been spoken.
    my problem is that i need to open that certain URL ( predefined) from a running application and not an applet, it hasn't worked for me, This is the only problem. is it possible ? please i need your help with this , i'd really appreciate it if someone would help ... thanks a lot for your time.

    hii guys am really sorry for the confusion ,the problem was actually with the java security poilcy not with the code as i thought.. i thought my code was wrong but it turned out to be correct.. here it is for anyone who's interested... but thanks anyway for everything... tc

  • How to call webservice from Java application

    Hi XI gurus
    Pls let me know how to call a webservice from Java application.
    I wanted to build synchronous interface from Java Application to SAP using SAP XI
    For example, i need to create Material master from Java application and the return message from SAP, should be seen in Java application
    Regards
    MD

    Hi,
    If your  JAVA Application is Web based application, you can expose it as Webservice.
    JAVA People will pick the data from Dbase using their application and will send the data to XI by using our XI Details like Message Interface and Data type structure and all.
    So we can Use SOAP Adapter or HTTP in XI..
    If you use HTTP for sending the data to XI means there is no need of Adapter also. why because HTTP sits on ABAP Stack and can directly communicate with the XI Integration Server Directly
    If you are dealing with the Webservice and SAP Applications means check this
    Walkthrough - SOAP  XI  RFC/BAPI

  • Open URL from Java in a new browser tab

    Hi OTN,
    Surprisingly can't find the implimintation.
    In an ADF managed bean I retrieve String url. I need to open a new browser tab with this url.
    Found this thread Open a url in a new window in the backing bean which shows using javascript "service.addScript(facesContext, "window.open(http://www.google.coml)");".
    But in my case in doesn't work. The code is executed, but nothing happens. Maybe because the bean is called from a taskflow inline popup.
    ADF 11.1.1.4
    Thanks.

    Well, I'm afraid that is not an option.
    The goButton is in a table row. There are lots of rows so if I use EL for Destination attribute the URL would be retrieved for each of rows.
    The method of URL retreiving is heavyweight operation which includes calling plsql functions, working with strings and others. So if I do it for each table row my application hungs and then I receive an exception of CPU usage.
    That's why I switched to normal commandButton witch actionListener which retrieves url on click - only once. So I need to open URL from Java.

  • How to open an PDF file from Java Application

    Hi
    I am developing a GUI application in java swing.
    on clicking one button, I want to open PDF file from my swing application.
    Is there any API through which I can achieve this?
    Tapan Maru

    Here's a way to do it (if I understand you
    correctly). Just let explorer.exe do it for you.
    import java.awt.*;
    public class openPDF
         Desktop desktop = Desktop.getDesktop();
         public openPDF()
              open("test.pdf");
         public void open(String path)
              try
                   Runtime.getRuntime().exec("explorer.exe "+path);
    } catch(Exception e) { System.out.println("NAI!
    I! ERROR!\n"+e); }
         public static void main(String[] args)
              openPDF myApplication = new openPDF();
    Why do you have a Desktop object as a member but instead of using it, you execute a command with Runtime (which is not platform independent!)???

    Try creating a page called launcher.html (for example). That does this:
    <html>
    <head>
    <script language="javascript">
    windowHandle=window.open("http://www.javasoft.com", "", "height=700,width=1000,status=no,scrollbars=yes,resizable=yes,toolbar=no,menubar=no,location=no,top=5,left=5");
    </script>
    </head>
    </html>Now you launch IE (or whatever) with this page using the Runtime class. After x seconds (after the second window has been launched) try killing the process. Hopefully it will kill the original window you opened and not the window you popup (the one without toolbars etc)
    It might kill both windows but I can't be bothered to test it. If it does you'll have to try and find a workaround.

  • Open OBIEE report from web application

    Experts, I want to open OBIEE report from a web application. I have a question regarding the security here. Say I login as 'USER1' in web application, I would have to pass 'USER1' in nquser parameter. Correct? Also, this report has access to 'Sales Group' users only. So, does 'USER1' in web application need to be assigned to 'Sales Group'? Or, any user in the web application can open this report as long as I pass nquser in the GOURL.
    thx,
    parag

    You don't need to specify group details.
    When the report hits OBIEE, it will determine the permissions based on the nquser.
    Hope it helps.
