Getting the entire dataTableEx contents

Hi,
I am working on hx:dataTableEx to get some records from the db and display on the page. This works fine.
I also wanted to create an Excel when one clicks the excel button on the page with the tabledata in it.
The problem is , though i am able to generate the excel, its always contain blanks. I binded the datatable to a backing bean. It works fine when displaying it.
But when i try to retreive the same values from the backing bean getter methods while generating excel.. i get nothing.
Can anyone please help me what the problem is.
Thanks in advance!!

The standard parsers don't seem to do a very good job with DTDs. I've used a package at
http://www.wutka.com/dtdparser.html
to build DTDs. I haven't found a better way to get an internal DTD into an XML document than to separately convert both to String and manually insert the DTD (with appropriate DOCTYPE, etc.) into the XML.

  • How do I get the table of contents to toggle? I opened it while reading one book I had checked out from my library, but it is still open when I start another book. I am using Adobe 4 and Windows 8.1 on my PC.

    How do I get the table of contents to toggle? It has remained open since I opened it while reading two books ago. Thanks for the help.

    Thank you for your advice. I followed your directions, but came up with the same results. However, I did discover that whenever I open up the iPhoto Library that is already existing on my MacBook a certain set of pictures shows up. But then when I open up the iPhoto Library from the Hard drive another set of pictures shows up. BUT not ALL of my pictures are showing up on the iPhoto Library from the hard drive. At least the last two years of pictures are not showing up?! Actually, it appears that all the pictures are there from when I started using iPhoto about 5 years ago up until around the time that I got my iMac desktop computer and started using that (2 years ago). I have noticed that more recent videos I have made are showing up in a folder on the hard drive, but will not appear when I open up iMovie?! Any ideas on how to access my pictures from the last 2 years off of the hard drive???

  • Can you get just your rear camera lens replaced or do you have to get the entire back screen replaced?

    I recently dropped my phone for the first time, and neither of my screens cracked but my rear camera lens did get scratched badly. I can't use it at all to take picture. It just shows up as a fuzy screen when I open my rear camera. My iPhone isn't even a year old yet. Now, I need to know if I can get just the rear lens replaced or if I have to get the entire back screen replaced? I also need to know if anyone knows how much either of these would cost? Or is it free with the one year warrenty?

    You would have to get the rear glass panel replaced, it is one part. Normal warranty does not cover accidential damage. You can do it yourself for 50$:

  • How to get the cropped page content

    Consider an A4 size pdf is cropped in Bottom and Right edges.
    If the user wants to open the pdf as A4 size then we are passing the rectangle size A4 to PDPage.DrawEx() method to get the page content.
    When we use like this, we are getting the full page content but our requirement is to get the cropped page content.
    Is there any way to get the cropped portion alone by passing the rectangle size as A4 to PDPage.DrawEx() method.
    But it is working fine for Left and Top edge cropping

    Have a look at this document:
    http://partners.adobe.com/public/developer/en/acrobat/sdk/AcroJSGuide.pdf
    go to the index and search for the term "Crop" or "Cropping" which has a hyperlink for page 70.  There you will find some JavaScript options for cropping the page from all sides which can then be saved using some other methods in the document.  I'm not sure, though, if JavaScript is what you're looking for.

  • Best way to get the entire history of User Activities

    Hi,
    We have a requirement to track the history (at least 1 year) of all the user activities. Currently we are using user stat which gives just 3 months history. Is there any other way to get the entire history?
    Heard about RBE.
    Can some one suggest on how to implement RBE? Can we use SAP database and GUI for RBE?
    Is there any other alternative?
    Thanks in advance,

    Switch on the Audit Log.  Lots of info here if you search on SM18/19/20
    Alternatively ask the Basis team to increase the retention of the log files so you can use ST03 for longer

    What “draining issue”?
    The iPhone 5 has a battery replacement program but it does not include the 5S.

    See this -> Find the serial number and other information for your iPhone, iPad, and iPod touch - Apple Support
    "On most iOS devices, you can tap Settings > General > About to see your device's serial number, IMEI/MEID, and ICCID. If you're using iOS 6 or later, you can tap and hold on the number to use the copy option, then paste this information into Apple registration or support forms."

  • I can't get the entire update file to download, 995mb then stops.

    995mb then stops. I can't get the entire file to download and this is a fast connection, says 23 minutes to download the file, but stops short. I have tried about 15 times over the last 7 hours, yet it always stops at 995mb.
    I've tried over wireless and wired, and wired is very fast, as I mentioned, it shows only 23 minutes to download the entire 5.3gb file. but it never gets that far. I'd wonder if we have a data cap on the network (work), but it allows me to download the same 995mb over and over.
    if anyone has experienced this, I'd like to know what you did to get it to download. thanks

    Downloading Mavericks requires a high speed broandband connection.
    Check your download speed here > Speedtest.net - The Global Broadband Speed Test
    Anything less than 15Mbps is too slow to download the 5GB file which may why it's timing out at 995Mbps.
    You may need to contact your ISP for upgrade options.

  • How to get the entire database from remote server to my server

    Hi,
    I am running a web application with sample data. Now i need to access the original data through this application. But the original data is located in the other server which is located in Mumbai.
    Now i need the copy of that database to my system(Chennai). with minimum effort.
    It is very urgent...
    Thanks in advance...
    Chaitanya.

    Hi
    Nicolas is right. You can also take advantage of exp/imp utility. That would not only get the entire db in one file but also the size will be a fraction of the entire db size.You can search for DataPump (that uses expdp and impdp) utility to expedite the export/import process.
    For simple exp/imp you can do the following.
    From Remote site(MUMBAI) issue
    ORACLE_HOME\BIN\exp file=c:\fulldbexp09sept05.dmp log=c:\fulldbexp09sept05log.log FULL=Y userid=system/pwd@connectstringOfyourdb
    Get a copy of fulldbexp09sept05.dmp and place it on your local drive in Chennai
    On Local Site (Chennai)
    ORACLE_HOME\BIN\imp file=fulldbexp09sept05.dmp log=fulldbimp09sept05 FULL=Y userid=system/pwd@connectstringOfyourlocaldb
    By this you can take advantage of having a different db name on remote and local sites. This is a fairly easy exercise. You just need to be sure that in your TNSNAMES.ORA you have correctly defined the connectString for your db.
    PS: Create a database on local server with default settings.
    Make use of following to create appropriate tablespaces and users if you desire ie.
    1. On Remote Site open SQLPLUS session and issue this command to find out the tablespaces, datafiles and their sizes
    SQL>SELECT SUBSTR(file_name,1,60) FILE_NAME, tablespace_name, bytes
    FROM dba_data_files
    GROUP BY tablespace_name, file_name;
    Now create the tablespaces on local sites using the result of the above query.
    2. On Remote Site open SQLPLUS session and issue this command to spool user creation script.
    SQL>spool c:\createuserscript.lst
    SQL> SELECT 'CREATE USER ||' IDENTIFIED BY VALUES '||'"'||PASSWORD||'"'||' DEFAULT TABLESPACE '||DEFAULT_TABLESPACE||' TEMPORARY TABLESPACE '||TEMPORARY_TABLESPACE||';'
    FROM dba_users
    WHERE username NOT IN ('SYS','SYSTEM')
    ORDER BY username;
    SQL>spool off
    Now edit this createuserscript using any editor and replace " with '. Copy this file to the local server and run it using @. This will create appropriate users.
    Let me know if you have any problems.
    Regards
    Adnan Mashhadi
    Nicolas I am not sure as how to eliminate the " in my script. Any comment will be appreciated.

  • In spool to pdf format i am not getting the entire recod

  • How to get the entire trace with dbms_utility.format_error_backtrace

    Hi,
    I made 35 procedures where test35 is
    calling test34 and test34 is calling test33 etc.
    division-by-zero is in test1 and format_error_backtrace shows the trace up to test31.
    Just curious, is it possible to get the entire trace?
    Thanks
    An example
    SQL> BEGIN
      2  EXECUTE IMMEDIATE 'create or replace procedure test1 as a number; begin a:=1/0; end;';
      3  FOR i IN 2..35 LOOP

    ORA-06512: at line 2                                   

    Out of interest, do you get any further back if each error message is shorter (e.g. a shorter procedure name)? From a quick test, SQLERRM is limited to 510 characters (doubtless documented somewhere though I can't find it just now) - the documentation says FORMAT_ERROR_BACKTRACE is not subject to the same size limitation, but that doesn't mean there is no size limitation.
