Exception message not thrown back to the page

Hello All,
I have a servlet that listens for some data. Everything works perfectly if the data is intact. I do a whole bunch of processing on the data and verify its integrity etc...
HOwever if something is wrong, my app throws an exception and I could see from the system outs that the exception message I want to send back to the browser is being printed. But the browser does not completly load the page. In internet explorer, the page status still reads "opening page ........ "
If I see the trace it is past the out.print) line where the error message has already been printed out.
Is this a browser issue? Any suggestions are welcomed.
Thanks,
Praveen.

The response of the servlet should go back to the mainframe system from which I receive the data. But for testing purposes I am sending the data through a url's get parameter. So I really do not want to make a error page.
What is bothering me though is that the response gets printed in the command window and still not shown in the page giving you the impression that the request was never fully completed.
Any ideas ?
Thanks,
Praveen.

A new tab opens by default as a blank tab (about:blank).
If that isn't the case then an extension has changed that behavior.

If I am using pages and deleted my page by mistake how do I go back? I have not saved or deleted the page.

You have deleted your page, but you have not deleted your page?
Which is it?
If you never saved it it is gone. If you saved it in Lion (OSX 10.7) with Pages 09 v4.1, there should be versions available when you mouse overv the document name at the top of the window.

What's the fix for this CS4 message: One or more of the pages specified are not valid page names

I'm trying to export two pages (a spread) as a PDF. I've tried a number of times, using various techniques, including exporting first to a .imx file. Each time I get this message: One or more of the pages specified are not valid page names.
How can I get this to work?
I can't attach the file because it is 11MB.
Thanks,

Are you using sections in your document? That may mess up your pagenumbering while exporting pages as spreads. Try to put + to front of page numbers... like +12-+13 (into Export dialog´s page range field)
Another option is go to Preferences > General and change pagenumbering view method from Section Numbering to Absolute Numbering.

Exception Message=Unable to connect to the VMM database because the database is in an inconsistent state.

Hello,
I have a problem with SCVMM 2012 R2, it always gives error when tries to "Run the dynamic optimizer" process. The process starts automatically every 30mins. When I analyzed report.txt file I found error message:Exception Message=Unable
to connect to the VMM database because the database is in an inconsistent state.Contact an experienced SQL administrator whenever this error occurs. In some cases, it may be necessary to restore the VMM database. If the problem persists, contact
Microsoft Help and Support.
NOTE: If I start the process manually, it completes without any errors.
Any help would be appreciated

I'm led to believe this is a bug in UR5 and I think it was a bug in VMM 2012 SP1 RTM.
Our TAM says this will be fixed in UR6. We had to turn off Dynamic optimizer or we could have rolled back to UR4 but there were other bugs in UR4 which hurt us more.

If the menu bar is hidden then press the F10 key or hold down the Alt key, that should make the menu bar appear.
Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"
* If items are missing then open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout"
* If a missing item is in the toolbar palette then drag it back from the Customize window on the toolbar
* If you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar set up.

The most resent alarm is

Hi,
Can you access the URL using a browser? Does it work with the credentials used for the RunAs account?
Strange error message though - are the account you are running the console with, present in the SCSM CMDB?

Exception is not thrown immediately in Hibernate 3. Why??

I am using Hibernate 3.
If I execute "session.update" and the update is not successful (e.g. value too large), the exception is not thrown immediately.
For example,
System.out.println ("pass 1");
session.update(dataBean) ;
System.out.println ("pass 2");
session.getTransaction().commit();
System.out.println ("pass 3");
I find if session.update(dataBean) fails, "pass 1" and "pass 2" are printed but "pass 3" is not printed. That meams Hibernate will not throw exception until I execute "commit". Can I force it to throw immediately (i.e. only "pass 1" will be printed) ?
Thanks in advance.

O/R mappers such as Hibernate and JDO generally defer communications with the database for as long as possible; for an insert or update transaction that will be until commit().
This is for several reasons:
1) general efficiency - a series of update() calls may modify the same attribute of an object multiple times; it's substantially more efficient to update the database just once
2) database efficiency - when a transaction is in progress, even when nothing is occuring in that transaction, more resources are consumed inthe database than when no transaction is active. For example, if a transaction updates a row and then 10 minutes later commits, then during that interval the database has to keep track of 2 different versions of that row and know which connections see which version of the row.
3) connection management - DB connections are expensive resources and once a transaction has started updating the DB, it has to tie up a connection for the duration.
In other words, no matter how long it takes to set up your transaction in Java, a good O/R mapper is not going to begin a database transaction until the last possible moment, which is at commit().
Can I force it to throw immediatelyYou can call commit() any time you want.
It sounds like you want the database to do your input data validation for you. That's wrong. You need to validate input (for size, length, whatever) before you attempt to put it in the database.

I have created PDF from hardcopy by using my scanner. After I run OCR option for my PDF by using Acrobat Pro 9. But "Text-to-speech" functionality of the PDF says that an error message comes up that says the page is empty when I turns on the read out loud

I have created PDF from hardcopy by using my scanner. After I run OCR option for my PDF by using Acrobat Pro 9. But "Text-to-speech" functionality of the PDF says that an error message comes up that says the page is empty when I turns on the read out loud option in Acrobat. Kindly help me to sortout this problems?

So I tried generating the same PDFs on two other computers that have Acrobat 9 Pro. Results were reproduced. The verdict is:
- complex PDF files (that is, containing cross-references, tables of contents, and bookmarks) generated by Acrobat 9.x Pro are roughly 2-5x larger than the identical file generated with Acrobat 8.x Pro.
- different PDF conversion settings make a negligable difference (less than 10% rather than 70-80%).
- using the "Reduce File Size" or "Optimize PDF" option cuts the file size roughly in half, almost always resulting in a "image downsampling mask" warning message, which requires acknowledgement (that is a problem for batch processing or automation).
- adding an Acrobat watermark to the file cuts the file size roughly in half.
- just using Save As to another filename has no effect on file size.
- generating the PDF in Acrobat 9 with links but no PDF bookmarks still results in the inflated file size.
- generating the PDF in Acrobat 9 without any links or bookmarks results in approximately the same file size as the Acrobat 8 PDF with full links and bookmarks.
It appears that Acrobat 9's manner of adding links is what's bloating the files, and in my case it's probably not related to images or image resolution/print quality. It's a shame, because Acrobat 9 seems to have made some improvements to the Review Tracker interface, and a few other bells and whistles which I haven't really gotten around to exporing yet. But unless I find a way to keep my links and the PDF file sizes comparable to what I was getting with Acrobat 8 Pro, it looks like I'm going to stay with Acrobat 8.

My hp 100 mobile printer will only print one page then quits. will not print all of the pages.

my hp 100 mobile printer will only print one page then quits. will not print all of the pages. i have rebooted, new install, and reset. still the same thing. when i look it shows that it is printing but there is nothing happing. i use this with my lap top.

Hello colt1,
Are you using Bluetooth or USB cable to connect to the printer? Did you install from the disc, or from the online program? When it sits there and doesn't print, does it eventually give error messages, lights flashing, etc.?
Thanks,

Hi,

If you disconnect the cable going to the serial device, do you still get the echo? If so you have something going on in the port setup. If disconnecting the cable stops the echo then the device you're talking to is doing it - which would be my bet. One thing to check is whether this might not be normal operation. I have seen devices that if a command was successful, it simply echo'd back the command string you had sent. Also many serial devices have setting for specifying whether they are to echo commands.

There is nothing wrong with the OS update.
Delete ALL your email accounts.
Restart Playbook
Put the accounts back and ensure they are all set with PUSH ON. Manual (push off) will burn battery.
Similarly delete your wifi connections and add back when required.
Turn off wifi is not connected to wifi.
Any "hunting for connection" in email or wifi will burn up battery.
