Included JSPs not displaying anything

Hi there
I'm using the JSP directive to include a small JSP into the main one, using
<jsp:include page="/Summary.jsp">
Everything was working fine until I did a change in the Summary.jsp and the included page just stopped generating the HTML. I have a feeling that it is a compilation error, but I just don't get anything in the screen or in the console window for catalina.
I tried using the <%@ page errorPage="/DisplayException.jsp"%> in the included jsp (Summary.jsp) but the redirection does not happen at all.
Do I have to turn some kind of flag in Tomcat to see the errors (either compilation or runtime) that happen in the included JSPs?
I'm using Tomcat 5.0.27 and JDK 1.5 running on Windows.
Thanks in advance for your time and help
Leo.

The problem is that you are getting an error after
the response is already committed (HTML is already
written to the client machine). That means that the
server can not redirect to the error page.
Your option are to make sure that you do not flush
the output buffer when you do the include:
<jsp:include page="..." flush="false"/>
and make sure that the page that is doing the include
has a big enough buffer:
<%@page buffer="20kb" %> (at the top of the page)
Setting this high enough should make sure that your
response is not committed before your error occurs,
and so you should get redirected to the error page.
The higher it is set, though, the more memory your
r server will eat up, so remember to turn it back
down when debugging is done.Hi Steve
I did that and I could finally see the exception. Thanks a lot for your help
Leo.

  • HT5429 maps on iphone 5 do not display anything

    Hi everyone. I recently bought a new iPhone 5 and I have a serious problem with my maps app. It does not display anything I search except the grid lines and pins. please help how can I fix it.  pls send the instructions at [email protected] Thank you in advance.

    It is not a good idea to put any kind of personal contact information in such a public forum.
    First, close the maps app. Double click the home button.  At the bottom, press and hold any app until a red circle appears on the top of each.  Tap the red circle on the Maps app.  Next, reset the phone:  press and hold the power and home buttons at the same time until the Apple logo appears.  Ignore the red slider if it appears.

  • Adf region is not displaying anything

    Hi,
    I am using adf region to display the data.For this I have created one bounded task flow with page fragments.
    In the page fragment I created one output tag to display something.this page fragment is dropped in task flow.
    Then I made one JSP page and drag the task flow and drop it as the region.The problem is it not displaying any data.
    I am using jdev 12. Can you please tell me whether I am doing anything wrong.
    Thanks,
    Harsh

    What do you mean by
    Then I made one JSP page and drag the task flow and drop it as the region.
    Did you create a jspx page or a jsf page. Depending on the fragment type it only works on a jsf page (jsf 2.0 page). 12c default is create fragments as 'Facelets' which only work in jsf Pages. If you want to use a jspy page you have to create the fragment as 'JSP xml'.

  • Onboard Graphics Card Not Displaying Anything

    I got a free MS-7613 (Iona-GL8E) motherboard from my friend 's friend which was fully working, he upgraded his motherboard and no longer wanted/needed it. This is the first PC I have ever started to build, I've worked on the, before and know a reasonable amount about them, but the problem I have with this is, the onboard graphics card doesn't display anything. I tried via VGA and HDMI on a monitor and TV, both outputted nothing. The wire and monitor definitely work. The motherboards seems to work fine, it used to beep when it had no RAM, since then I bought RAM and it's been fine. I had a graphics card in but removed it as it also displayed nothing. All the USB drives work and it turns on fine, it just display nothing. Could it be because it had a graphics card in perviously and doesn't display anything because of that? Any help would be great!

    Hey everybody! I was trying to hard reset my phone when all of a sudden it got bricked. It got stuck on the spinning cog wheels for a good two hours, so I decided that I might as well try to unbrick it with this guide: Tip: How to fix a bricked Nokia Lumia 920 | Windows Phone Central Well, that didn't go all that great. It turns out now my phone won't even display anything. It's just a black screen, a plain black screen. When I plug into the computer it still makes the noise but other than that nothing will else will work. Is there anything I could try for now or is a complete goner? Someone else had the same issue and I'll quote him, as it's a bit more descriptive: "Hi guys,
    I've a Nokia Lumia 820 who is bricked and have nothing displayed on screen, no spinning gears, no lighting... So I've tried the step here and the Nokia is detected by Windows (tried on 7 x64, 8 x64, and a XP VM), but strangely detected and no detected (like plug-in and plug-out) and then the Volume Down + Power don't do anything.
    Some one have idea to make my Nokia working again... (i've an old iPhone for now... help me please ! )
    Etienne"
    That was a comment made at the very bottom of the guide. I'm having that same issue. Thanks for any help that I can get.

    The only solution left seems to be a visit to Nokia Care. Be informed that you have already voided Warranty by following unauthorised process mentioned in the link pasted by you ..BTW, there are quite a few suggestions on THIS Forum (to resolve your original problem) that you would have tried without voiding the Warranty.

  • Macbook pro does not display anything

    Model is Macbook Pro 15" Mid 2009 Unibody
    Mountain Lion
    Modifications:
    CD drive replaced with additional 500 GB Hard Drive
    One of the 2 GB RAM chips replaced with a 4 GB chip
    Earlier today I was browsing the internet on my MBP and suddenly the laptop froze, the screen froze, the mouse and keyboard were not responding at all, which eventually led me to have to force shut it down (by holding the power button). When I tried to turn the laptop back on it started up (as in I could hear the fan and the white light came on) but there was no display and then 4-5 seconds after it turned off and then started up again by itself and stayed on, still no display on the screen at all, its off and the keyboard doesn't seem to be responding either which I figured by trying to press the caps lock button to see if the green light comes on in which it didn't.
    I have tried pressing the Ctrl+Shift+Alt+Power button and then turning the laptop on but the same problem still persists. The laptop starts up, turns off and then starts up again and then stays on with nothing displayed on the screen and no response from the keyboard. The start up chime also doesn't occur. I am unable to start the laptop in Safe mode or any other mode that requires me to hold a button when powering up as the laptop turns off after 4-5 seconds and then starts up again. I have looked online to find anyone with a similar problem but can't seem to find any posts regarding this.
    The laptop has not been dropped or anything, neither had it experienced any liquid damage. It has been running smoothly before the problem that occured earlier. I am in desperate need of my Macbook Pro and there doesn't seem to be any Genius Bar appointments available in the next 7 days in any Apple store near to me (Central London).
    Any help or advise will greatly appreciated.
    Khal

    Make that genius bar appointment and wait those seven days.  That is your best option to get it diagnosed properly (for Free).
    Ciao.

  • Account Details page transaction link do not display anything

    Hi,
    I extended the TransactionTableVO to include new columns. Initially, whenever I click on the transaction link, I get an exception error. But I fixed it by commenting out functions that seem to overrride the original one (like setIrSalesOrder, setAmountDueRemainingFormatted etc). It worked for Payment transaction type but not for the other types like Credit Memo, Chargeback, Invoice, Debit Memo, etc.
    This Transaction link displays different pages according to the transaction type. I don't have any clue why it worked for Payment transaction type but did not work for the rest. There is no error just blank content.
    I opened the original TransactionTableVORowImpl.class and found the following code possibly related to this issue:
    public static String getStaticTransactionDetailsRegionCode(InvoiceTableVORowImpl invoicetablevorowimpl, String s)
    String s1 = null;
    if("INV".equals(s) || "GUAR".equals(s) || "CB".equals(s) || "DM".equals(s) || "DEP".equals(s))
    s1 = "ARITRANSACTIONDETAILSPAGE";
    } else
    if("CM".equals(s))
    s1 = "ARITEMPCMDETAILSPAGE";
    } else
    if("PMT".equals(s))
    s1 = "ARI_PAYMENT_DETAILS_PAGE";
    } else
    if("REQ".equals(s))
    s1 = "ARITEMPCMREQUESTDETAILSPAGE";
    return s1;
    public void setTransactionDetailsRegionCode(String s)
    setAttributeInternal("TransactionDetailsRegionCode", s);
    I checked the URL and it does contain the correct name of the page i.e. if it's an Invoice transaction type, it includes ARITRANSACTIONDETAILSPAGE in the URL. So it is getting the correct page to redirect to. The window title, however, contains the following:
    Message not found. Application: AR, Message Name: nullTitle
    Any assistance is greatly appreciated!

    I think I'm not passing the correct paramaters. I checked the URL and it's not passing any &Irtransactiontype. How can I check where this parameter is coming from??

  • Dbms_output.put_line not displaying anything

    I am running the below code (ssn_run.sql) using sqlplus 10.2.0.1.0 on my windows XP professional client PC.
    The database is a Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit running on Solaris
    I cracked my head for about one hour but couldn't figure out this :

    The SELECT statement that comes in the for loop should return data as v_personid has a value. (I tested this by a select statement)
    However, I am just not able to display the line which comes in the inner loop :
    dbms_output.put_line('i.person_other is : '||i.person_other);
    The result of this dbms output put_line neither shows up on the screen, nor it gets written to the spool file...I am stumped with this...
    The other dbms_output put_lines that display error displays okay, but not the one in the inner loop.... Can someone help me out if you see any obvious issues here........
    Also my UPDATE MEMBER statement inside the for loop doesn't do anything whereas it was supposed to update a row !!
    Thanks

    You could display the number the query return by adding;
    v_count number;After you assign v_personid;
    dbms_output.put_line('v_personid  is : '||v_personid );
    (select count(*)
    into v_count
    from person_relation
    where relpersonid in(
       select personid
       from person
       where PERSONID = v_personid)).
    dbms_output.put_line('v_count  is : '||v_count );

  • Included JSPs not compiling

    I have some JSP code which does not compile in JDeveloper but works fine when deployed in a web server (Websphere).
    There is a page called main.jsp with code like:
    Map clientDataList = (Map) request.getAttribute("clientDataList");
    <%@ include file="standard1Page.jsp" %>
    clientDataList is set in a servlet which forwards to main.jsp. On standard1Page.jsp I want to access the clientDataList object:
    <%= clientDataList.get("sitealignment") %>
    But standard1Page.jsp does not compile in JDeveloper because clientDataList is not defined on that page:
    Error(2,75): variable clientDataList not found in class _standard1Page
    Is this a fundamental problem with JDeveloper not following through the "includes" when doing the project compile, or is there something I can set to make this stuff compile. If not I'm going to have to edit my JSPs in a text editor so I can compile my project.

    Francis The problem is that "standard1page.jsp" is not a JSP page, it is just a text fragment to be included in a real JSP page. As it's just a fragment, it won't compile correctly as a JSP page. If you add it to your project as ".jsp", JDeveloper tries to compile it.
    A common convention for JSP included fragments is to name them with a".jspf" suffix, so it's relatively clear what they are, and to make the IDE not compile them as JSP pages.

  • Finder not displaying anything

    Recently the finder on my macbook air has quit displaying all programs, the only files that appear in finder are the ones in desktop, but when opened they also appear to be empty. I know that the software hasn't been deleted or anything because i can find it using spotlight. Any help?

    Not sure how you did the SMC reset however here is the correct way, try that first. It's OK to do 2-3 of them.
    SMC RESET
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    If that still doesn't work re-start the compute in Safe Mode, it's possible a cache may have become corrupted. A Safe Mode reset will clear some caches.
    If the SMC reset and Safe Mode restart don't help then reinstall OS X using the Intall USB drive that shipped withe computer. Don't worry it won't affect your data at all.
