Interesting!!! But, who's bug is this? JSP?

copy the following code and save it as jsp. then run this jsp page on either weblogic or tomcat servers, you can see the 'count' incremented twice. and I think this is not a browser problem, since this occurs on both netscape or IE. So, this may be a JSP or servlet bug? If anybody know the reason please reply to [email protected]
Listing: zenTest.jsp
<%
out.println("inside maze :)");
int i = 0;
if(session.getAttribute("iTmp")==null){
     session.setAttribute("iTmp", "1");
}else{
     i = Integer.parseInt((String)session.getAttribute("iTmp"));
     ++i;
     session.setAttribute("iTmp",""+i);
System.out.println("count is "+i);
%>
<HTML>
     <HEAD>
          <TITLE> Report </TITLE>
     </HEAD>
     <body>
          <table background="#FFDEFD">
               <tr>
                 <td>Hi</td>
               </tr>
          </table>
     </body>
</html>
<script>
     alert('1');
</script>

Not sure what you meant by "the 'count' incremented twice". When I tried the JSP page, I got 0 the first time, and 2,3,4... on subsequent refreshes. It behaved as expected.

I bought LR 5 on Oct 16, 2014. I just tried to export photos with watermark and it wont work. After reading tutorials and following directions, only a few photos out of 100 show up with watermark, but not everytime. Is this a bug and how does it get fixed

I bought LR 5 Oct 16 this year. Why doesn't my watermark work when I export photos? I followed tutorials and still it does not work. Once, a few photos out of about 100 exported with the watermark, but only once. Is this a bug? how to fix? Also, how to I get rid of unwanted presents?

Are you exporting as JPG or TIFF or PSD?
Any other format (including "Original") will not show a watermark.

Bug in viewCDZDocument.jsp?

When the 'refresh on open' option is clicked on, viewCDZDocument.jsp calls getPrompts.jsp. We modified getPrompts.jsp to access the document's data providers. This puts the system in some weird state where it doesn't think there is any data returned by the query, and it displays the "No Data Retreived" message. But when I change viewCDZDocument.jsp to call refreshDocument.jsp in the case where the 'refresh on open' option is clicked on, I don't get the message - everything works great. Makes sense too - why would it call anything other than refreshDocument.jsp in this situation. Therefore, I think there is a bug in viewCDZDocument.jsp.
Any opinions?

I want to update my current iOS from 4.2.1 to 5.0.1 for the Assistive Touch feature that allows you to have an on screen home button
I tried downloading the file myself (not through iTunes), making sure I got the iPod 4G file. Go into iTunes and install it and it says it cannot upgrade because the firmware is not compatible
iOS 4.2.1 - there's a clue. It begs the question about which model of iPod you have. Yes, I know you said: (and yes, I have a 4G) by which I assume you're saying that you have a 4th generation Touch, but are you sure? This has been claimed before by people who then discover that they do not have a 4th gen Touch. Which size Touch do you have and what is the model number on the back of your iPod? If it says model A1288, that's a 2nd generation iPod Touch. Check this page http://support.apple.com/kb/HT1353 for help in identifying your model of iPod.
The second clue - and the reason I've mentioned all this, is that you then say you have downloaded the file yourself but "it cannot upgrade because the firmware is not compatible." In other words, iOS 5.0 cannot be used with your iPod. That also suggests that you have 2nd gen Touch.
Persumbaly, you have tried connecting the Touch to iTunes and selecting "check for updates?" What does it say?

Is there anyone there? I hope there is someone who can you understand this problem and have the common sense to respond?
I open gmail. I want to save an email to one of my folders.
I position my cursor over the appropriate Folder icon or by choice, to the Trash.
The friendly finger pointing cursor icon changes to an arrow icon.
The hand icon allows me flawless access to opening and/or moving emails.
The arrow, however does not open the link.
On the Google menu bar the cursor hand with finger opens the links to Everett (my name), Search, Images, Maps and Play.
When I attempt to open the remaining links in the menu bar (YouTube, News, Gmail, Drive, Calendar and More) the arrow icon replaces the hand. The arrow icon does not work. It will not activate these links. Nor does it open email messages in the Inbox.
Usually I reset, even reboot Safire and sometimes the problem goes away, then reappears.
Can you imagine if this condition should it happen to a tech savvy Google Support person? Perhaps one can share and make my problem go away.
I am considering dropping Google as my mail source. Unfortunate!

I have uninstalled my Access Connection, but this problem seems to persist. IBM technician have changed the wireless card of my T60, the first few days after it was changed was very fine, no problem at all. About a week later, the problem occured again, and it happened quite frequently after that occurence. Now i really have no idea what is the cause and how to solve it. Will be greatful if there is anyone that can help me.

First call attempt fails with 12000; reason="Routes available for this request but no available gateway at this point"

We've installed a new Audiocodes Mediant 1000B gateway for our customer. They only have about 6 users enabled for Enterprise voice and using Lync for all calls. They have an intermittent problem whereby the first call attempt to a number on the
PSTN fails with 12000; reason="Routes available for this request but no available gateway at this point". There is only one PSTN gateway installed. All routes point to this gateway. What I found initially is that the calls
were failing after 10 seconds which is the default "failovertimeout" in the OutboundRouting.exe.config. I found this post http://voipnorm.blogspot.co.uk/2012/06/lync-2010-gateway-timeout-call-failures.html and
changed the value to 20 seconds. Subsequent failures failed after 20 seconds (the new value). The interesting thing is that the second attempt even a couple of seconds later succeeds. My Lync server event log has 46046 "A call to a PSTN
number failed due to non availability of gateways." for the failed call and 46047 "A PBX gateway is now responding to requests after some failures." for the successful call moments later.
My environment is Lync 2010. A single enterprise edition Front End with collocated mediation. The server is virtual and in a different physical location to the gateway. The two sites are connected via a LES1000. The RTT between the
sites is very low so it isn't necessarily networking.
In the Syslog output on the Audiocodes we don't see the call even reach the gateway. It's likely that Lync has simply marked the gateway as down and doesn't route the first call. Then it wakes up and marks it as up and routes the next call.
Update wise I'm on 4.0.7577.183, 199 and 217 for those that are up to date and the only components that are behind say that 223 is available. Those being Core Components, Lync Server, Conferencing Server and Web Components.
As I said, this is intermittent, apparently doesn't happen for every user (which I don't buy), but is easily replicated on request.
I definitely think changing the failovertimeout value has reduced the number of failures. But realistically I don't want users sitting there for 20 seconds before their call fails. Or 19 seconds for the call to route.
I've found a few posts on this and similar issues. I don't get the 25051 or 25052 errors.
Any help gratefully appreciated.

I have an iPhone, but cannot use it at this time. So Im trying to text off my iPod, but it only comes up as my email. How do I make it use my iPhone number?

I have an iPhone, but cannot use it at this time. So Im trying to text off my iPod, but it only comes up as my email. How do I make it use my iPhone number?

The iPod will only have a phone numnber for Messages and FaceTime if the same ID is currently being used with an iPhone with iOS 6 and and that ID is used for Messages and faceTime.
There is no way to add a phone number to an iPod otherwise.
Also, on the iPod yoo can only send and receive Messages from other users who use the Apple Messages app.

A small but very irritating bug in Mail: after pressing the spacebar after typing an apostrophe in a word such as "we're", the cursor moves to the left i.e. backwards, and not to the right, effectively deleting a space and not creating one.

When composing an email in Mac Mail I've noticed a small but very irritating bug: pressing the spacebar after typing an apostrophe in a word, e.g. "we're", the cursor moves to the left i.e. backwards, and not to the right, effectively deleting a space and not creating one.
Any ideas?

I just recreated this problem on my iMac (wired KB, no wireless KB) by changing Mail > Preferences > Composing > Spellcheck from "as I type" to "never". Then type a contraction ending in 're and the space bar causes the cursor to jump back as others have stated, to the spot 'r|e
Next, I went into System Preferences > Keyboard > Text, and turned off "use smart quotes" and the problem went away again.
From this point (smart quotes off, spell checking never), if I turn Smart Quotes ON, the problem returns.
The problem is dependent on the state of both settings.
The spacebar in Mail "works" if I have either of the following setting combinations:
Keyboard: smart quotes OFF, Mail: check spelling ANY SETTING
Keyboard: smart quotes ON, Mail: check spelling AS I TYPE
Other combinations FAIL
Keyboard: smart quotes ON, Mail: Check spelling NEVER
Keyboard: smart quotes ON, Mail: Check Spelling WHEN I CLICK SEND
Looks to me like there's a bug in Mail > Preferences > Check spelling > NEVER and WHEN I CLICK SEND that interacts badly with Keyboard > Smart quotes ON.
Thanks.

Annoying but not fatal bug uncovered in Aperture file size metadata.

The bug described below was found as a result of testing the relative print sharpness of the Aperture print routines. I printed an adjusted Canon 5D image with Aperture's print routine to a 4X6, 300ppi print output, then took the same image through P'shop, (as a PSD) downsized the file to the same dimensions and converted it to 8-bit color depth. Then printed the returned file through Aperture.
To my surprise when I was performing this comparison, I found that the file size shown in the metadata panel of the test file was not reduced, even though I had significantly downsized the file (from an "outbound" 72.2GB to an "inbound" file of slightly less than 7GB. So I repeated the round trip to P'shop, using the OSX Inspector to examine the relevant .approject size at three points in the workflow:
1) Before executing the "Open in External Editor" command;
2) After the PSD version had been created by Aperture; and
3) After re-sizing the file in P'Shop and saving it back to Aperture.
The net of the test was as follows:
1) The size of the base (pre-export) .approject increased by approximately 72.2GB when it created the 16-bit PSD file for export to P'shop - exactly what the metadata showed and what I expected for a 5D file at 16-bit color depth.
2) When the resized file was returned from P'shop, the base .approject file was now only 7.5GB larger, indicating the size of the returned file was in fact reduced by the downsizing.
So the problem is not creation of an abnormally large Aperture PSD file. The metadata file size is simply not updated when the downsized file is returned from P'shop.
I submitted a bug report to Apple on this, but I'm not sure what priority it will get. So this is an FYI in case others have observed a similar phenomenon and been concerned about it.
BTW: The file downsized via the P'Shop round trip was noticeably sharper on printing (from Aperture) than the print produced directly out of Aperture. So it appears the print output sharpening routines in Aperture still need considerable improvement. That's the improvement I'd rather have Apple spending their time on than an anoying but not fatal bug in file size metadata.

There is a possibility that you've bought a stolen iphone which has an iClould lock on it. The only way to remove an iCloud lock is to contact the previous owner of your phone and inform him of your problem. But you dont know who the previous owner is hence you cant unlock your phone. Do a fresh restore with itunes by connecting your iphone to your pc, opening up itunes and clicking restore. I'm not sure if that'll help, but it's worth a try. Hope I helped. Cheers

My husband shares my Apple ID but now I see that this causes problems so how can I take him off my account so he can get his own Apple ID ?

My husband shares my Apple ID but now I see that this causes problems. So how can he get his own Apple ID for his device?

I agree that having separate Apple IDs is a good idea. It helps keep things from getting confused between two user who might have different needs and wants on their devices.
You husband should save and backup to a computer all the files, photos and music that he wants to keep. He should also save any files created with the apps on his device. Once that is done he can use the Settings app to erase his device.

He can then set up his device as new and create an Apple ID for himself. Once the device is up and running he can purchase and/or download the apps he wants and sync with a computer to restore the photos, files, etc.
To make syncing easier, with two Apple IDs, I suggest that you each use a different computer to sync with OR you have separate accounts on one computer. This way there will be two separate iTunes libraries and syncing with each will be straightforward.

after deployment on J2EE 1.4 I can access the html page but when trying to get the jsp I get this error
org.apache.jasper.JasperException: Unable to compile class for JSP
No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
If using an alternate Java compiler, please check its installation and access path.

Have you done this?

Looks like you need to set the classpath for java on your system,
Try adding this to startup.bat (or sh on linux)
@echo off
set JAVA_HOME=c:\j2sdk1.4.2_01
if "%OS%" == "Windows_NT" setlocal
