  • Not getting the Exception_.toString in Forms

    Hi,
    I hope someone can help me.
    I have a java jar file. The jar file executes properly from the command prompt. The functionality in this java method is to call a HELLO WORLD service of a hosted webservice. So on its own the jar works fine, I know this because I get a successful response from the service.
    Now I followed steps from this link
    http://www.oracle.com/webfolder/technetwork/tutorials/obe/forms/webservicefromforms/ws_10_1_3_from_forms.html to import this webservice jar into Forms and call the methods exposed from the jar.
    Now I have two methods a simple multiply(a, b) which accepts two numbers and returns back the value. This works fine.
    I have a second method callWebservice() where I call the webservice method and return a successful message.
    When I call this method from Forms, I must be getting an error because it goes into the exception
    1.EXCEPTION
    2. WHEN ORA_JAVA.EXCEPTION_THROWN then
    3. SHOW_MESSAGE('VAL_ALERT','444');
    4. SHOW_MESSAGE('VAL_ALERT',Exception_.toString(ex));.................
    I get the alert on line 3, but I don't get the next alert Exception_.toString().
    Any help? please....

    You did not mention what Forms version you are using so I will assume 10.1.2 based on your comments.
    The server side jre/jdk has nothing to do with the client. Forms 10.1.2.3 is certified to use JRE 1.6.0 on the client side. You cannot update the server side jdk beyond 1.4.2 as it can damage the installation. As mentioned, the server side jdk has nothing to do with client side anyway.
    The only restrictions to using JRE 1.6 on the client is that you are using 10.1.2.3 and IE7 or IE8. You could also use FF3. Refer to the certification matrix for Forms 10.1.2 to see the details:

    Chrome uses a different and separate plug-in.
    There are things about IE you need to know, especially 11. Specifically:
    "User-Agent Strings"
    That doesn't mean a lot, I'm sure, but it's the root of your problems, and Flash Player has nothing to do with it.
    Microsoft "rewrote" the User-Agent Strings for the abomination they call their latest and greatest browser. User-Agent Strings are what websites use to identify the browser you're using and provide the proper content for it's browser engine, like ActiveX stuff, and Flash or HTML5 video. Thanks to the geniuses in Redmond, WA, the User-Agent Strings for IE11 (which has a Trident engine), ID it as either "Gecko" (Firefox) or "Webkit" (Chrome). Problem is: when the site the directs to the content for one of these two engines, the Trident engine in IE can't intepret it and the site then sees IE as an "unidentified" browser.
    The problem with an unidentified browser is that the plug-ins in that browser aren't recognized either, so even though you're up to date, it says you need the latest Flash Player when you use IE11. YouTube... has converted to HTML5 video so if it doesn't detect Flash Player, it can display HTML5 (MP4) video which requires no plug-in to play. Facebook can't do that, because HTML5 doesn't apply to games... only video.
    Microsoft has no plans to "fix" the mess they've created because they think it's a great idea to block you out of the websites you visit.
    They recommend using "Compatibility View" and pretending that you're using an older verison of IE... Problem with that is that it's seen limited success, and you have to enable it for EVERY page that has problems... individually.
    I'm not big on "pretending" so I recommend actually using another browser.
    Firefox (from Mozilla)
    Opera (from Opera)
    Safari (from Apple)
    Chrome (from Google)
    ANY of those will work where IE11 won't, with the Flash Player Plug-in (For all other browsers), and Chrome doesn't even need that because it has its own Flash Player plugin built in.

  • Can not get the parameter?

    I use a form to upload files,
    like this:
    <form name="gdform10" action="upload.jsp" ENCTYPE="multipart/form-data" method="post">
    <input type="hidden" name="picName" value="wxds.jpg">
    <input type="file" name="file">
    <input type="submit" name="savePic" value="modify">
    </form>
    but I can not get the parameter picName in the upload.jsp,
    like :
    String pname = request.getParameter("picName");
    but pname is null.

    Hello,
    In Jsp, if you want to upload file, you can't directly use "request.getParameter()".
    There're two company provide components for you and it's free.
    First is jspsmart company, it offer jspsmartUpload component and link is
    http://www.jspsmart.com
    Second is o'reilly, it offer MultipartRequest component and links is http://www.servlets.com/cos/javadoc/com/oreilly/servlet/MultipartRequest.html
    for example, you use oreilly component.
    <%@ page import="com.oreilly.servlet.MultipartRequest" %>
    String saveDirectory = "c:\\Upload\\";
    int maxPostSize = 5 * 1024*1024;
    MultipartRequest multi= new MultipartRequest(request,saveDirectory,maxPostSize );
    Enumeration filesname = multi.getFileNames();
    while(filesname.hasMoreElements()){
    String name = (String)filesname.nextElement();
    FileName = multi.getFilesystemName(name);
    File f = multi.getFile(name);
    String ContentType = multi.getContentType(name);

  • Can not get the Cisco TSP to show UP - 2003 64bit

    Can not get the Cisco TSP to show up on the list of Providers in Phone and Modem Options- Advance tab. Installed ver. 4.1, it seems to install correctly, with no errors but when I restart the server, there is no Cisco TSP001.tsp in the providers list. It works perfectly on my Windows 2003 servers, but will not work on this new Windows 2003 64 bit server. Any tricks to getting this to load?
    Thanks
    Keith

    Hi
    There is no 64-bit TSP yet. Whilst 32-bit apps will work OK for the most part on 64-bit via the WoW function, drivers tend to not be so flexible, and that's what TSP is...
    You'll have to bother your Cisco accounts folks to get this prioritised, it is upsetting a lot of people...

  • PAYABLES NOT GETTING THE REPORT OUTPUT IN PDF AFTER APPLYING RUP5 R12

    Hi All,
    RDBMS:10.2.0.3.0
    Oracle Apps :12.0.4
    OS:AIX 5.3
    Problem Description:
    We are presently facing an issue in Payables not getting the report output in PDF esp for the reports "Invoice Register", Invoice Hold Report and also other reports. We were able to generate the reports till our last test performed on last Thursday. This instance was cloned over the last weekend and probably the new upgrade to RUP5 R12,would have impacted it.
    Concurrent Programs submitted are completed normal but on clicking "view output" results in Blank PDF output.
    The error message what was shown is as below:
    "Adobe Reader could not open 'AcrC.tmp' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)".
    Where could we locate ther above 'AcrC.tmp' of Adobe Reader..
    could anyone please share such an experience encountered for resolution..
    Would appreciate an early response..
    Thanks for your time!
    Regards,

    I suggest you speak to your DBA/sysadmin. This is not likely to be a reports problem.
    Check that you can see the output from apps through the viewer (the report may not hav output anything)
    Check whether you can print anything on that printer from apps.
    May also be worth checking to see if you can print to another printer from this report.

  • I have an iPad 2 and the newest apple tv. I do not get the option on my iPad to mirror on AirPlay. I've tried all the suggestions I've seen. Does anyone have a new idea?

    I have an iPad 2 and the newest apple tv. I do not get the option to turn mirroring on in the AirPlay function. I have tried the suggestions I've seen on here so far, but nothing has worked. Has anyone come up with a fix to this problem?

    Your Apple TV and iOS device (iPad) need to be on the same network subnet.  If they are you can verify when playing that the ATV is set as the output device by clicking the icon to the the right of the fast-forwrd button.  Or you can double-click the home button and swipe left twice to see this.

  • When I go into More 4 Catch up TV I do not get the bar that allows you to pause, enlarge, scoll forward when I click onto a programme is this Firefow or More 4? Can you help me fix?

    When I go into Channel 4 website to catch up on tv programmes on any of their channels I do not get the task bar to be able to pause, select point in programme to start from etc. Happens in both play and play in pop up. So if I play I can not make large screen.
    Don't know where problem lies but others in house who acces same web site do not have this problem and I am the only one that uses firefox.

    That file might have moved to a different location on the server. I think you'll need to check with RefWorks support or your local IT department on why the install page links do not work.

    I Just received the update to iTunes, when I I look at the screen I do not see the normal icons.  When I select movies I do not get the new downloads unless I select the list in the sub file. How do I get back to the old method of seeing and using iTunes??

    I can tell you that this is some of the absolutely worst customer service I have ever dealt with. I found out from a store employee that when they are really busy with calls, they have third party companies taking overflow calls. One of those companies is Xerox. What can a Xerox call center rep possibly be able to authorize on a Verizon account?  I'm Sure there is a ton of misinformation out there due to this. They don't note the accounts properly or so everyone can see them. I have been transferred before and have asked if they work for Verizon or a third party also and was refused an answer so, apparently they aren't required to disclose that information. I spent a long time in the store on my last visit and it's not just customers that get the runaround. It happens to the store employees as well and it's beyond frustrating.
