Long.parseLong("2") returned 6001
I ran into a really strange issue where Long.parseLong("2") started returning 6001. Here is what happened:
- This happened on windows 7 - 64 bit OS and in an application running on the weblogic server - v10.3.2. Weblogic was set to use jdk160_14_R27.6.5-32 that comes along with it.
- When this started happening, I debugged the server using eclipse and entered the expression Long.parseLong("2") in the eclipse-debug expression window. This itself was returning 6001.
- Even Long.valueOf("2") returned 6001.
- Other values - like Long.parseLong("1"), Long.parseLong("3"), Long.parseLong("4"), Long.parseLong("8"), etc were fine.
- I tried giving a radix of 10, etc but nothing helped
I suspect there was some corruption in the JVM due to which the representation of 2 got screwed.
Do note 1 thing, this started happening on a morning when I had resumed the machine from a hibernation that I had done the previous night.
It so happened that when I had hibernated the machine the previous night, the debugger was attached to the JVM and thats the state the machine was hibernated in.
I have done this many times on previous occasions but never came across any issues. I am not sure if this could be the cause of the issue.
I restarted the server and all was well after that.
Anyone having any clue what could have happened here ?

Well an application couldn't actually do that without a hardware fault.Not sure what scenario you are referring to.
But one application can certainly mess with the application space of another on any modern desktop OS.
For example the following windows method.

And if it does it incorrectly then it would cause some really odd error in the target app.

How does this work: Long.parseLong(String)
I am passing a string: "MM/DD/YYYY HH:MM:SS:MM" into the method Long.parseLong and it correctly gives me the epoch time as a long. Is this suppose to do this, or is this a freak thing? Does parseLong know that this is formatted as a date and correctly translates it to epoch? I searched api and cannot find anything.
Thanks!Sorry, I am apparently an idiot. I am using a servlet. When the user clicks on a link it sends the time to a servlet which retrieves it from a database. The link is formatted as a date, but the actual href sends the epoch time. So it is a simple conversion to a long. Thanks anyways!

Problem with a ColdFusion (Queries spend a long time to return)
Hy guys
My team have a problem with a Coldfusion (version 8,0,0,176276). Apparently this issue has a relation with queries that spend a long time to return some result, making the poll to open more connexions with the database until stop the application.
Actually the high number of connexions is a reflex of this issue, a consequence and the same way that is the fail on the application.
I would like to know if exist a way to debug the calls to database? this information will help my team a lot.
Thank you.

How long before user returns chart in azure preview portal
Hi,
I am trying to figure out how to add "How long before user returns" chart from VS Online AI dashboard to the azure preview portal. Any advice how to do that?
Thanks,
PVTry out these steps on Azure Preview Portal:
1. On Application Overview blade select Users chart
2. On opened Metrics Explorer blade select grid under charts
4. In "Group by" combobox select a property by which to group the average time before user returns.
3. In chart details select metric "Time between sessions (Avg)"

Long delay before returning to menu
I've made several movies and burned them using iDVD in the past, but I've never had this problem. After the movie is done playing, it takes at least a good minute to two minutes for the main menu to come back up. Any idea what is wrong or how to fix it?
It sounds like you miight have some extra space at the end of your movie. Sometimes a stray fragment of audio or video left over from editing gets located down the time line from the end of your movie. They can be tiny and hard to see. The movie will then play out with a dark screen until it reaches the "end" at that stray fragment, before returning to the menu. Expand your time line as wide as it will go and do a careful search for any such fragments and delete them.
Also, if you have music that has been muted but extends out past the end of your movie, the dark screen will play out until the end of the muted song before switching back to the menu.
Although unlikely, for some reason you may have left an extra long black clip at the end of your movie. (It happened to me once,)
If none of the above resolves your problem, try using the search function of this forum. I have seen your issue come up a lot. -

Long run report returns a empty page?
Hi,
My report takes about 10 minute to run, it worked on report developer (local pc), but return a empty report if run from URL against the report server (on Unix box). What might be the problem and how to fix it?
Thankshello,
what desformat did you use ? does that reproduce with all desformats ?
sometimes, if you use PDF as the desformat, Adobe Acrobat Reader is not invoked correctly, which results in an empty page.

For some reason this stopped working on firefox a week or so ago. I have tried to uninstall and install firefox again but the problem still persists. I've tried both chrome and explorer and they don't seem to have this problem.
I'd hate to stop using firefox but this so annoying that in less i can fix it, i'll have to change my browser!Hi larryhall,
I'd try starting Firefox in [[Safe Mode]]. If you don't have the issue while all of your add-ons, extensions, and themes are disabled, you can try adding them back in one by one until you find the culprit. You should look at the [https://support.mozilla.org/en-US/kb/Troubleshooting-extensions-themes Extensions and Themes troubleshooting guide ] and the [[Troubleshooting plugins]] article as well.
Hopefully this helps! -
Downloads take to long, had to return it.
Well I was really hoping that my new TV would allow me to not have to rent movies from Com?????ast, But, i went online (via TV) and rented and HD movie. 5 hours later, it was at 23% downloaded and what is odd is that I have rather fast broadband. Anyway, I have no idea what make me think that I could actually see the movie right after I rented it. Well perhaps I'll just save the money and wait for a MBP refresh.
Unfortunately I see both sides of this issue. I wish I could view the movie sooner but at the same time I want high quality audio and video. I guess in most cases the two can't go together,
I just rented The Brave One and it appears it will take a total of six hours via my T1 (my connection is the bottleneck not their servers). I can live with the download speed but movie renting certainly won't be an impulse purchase.
I do wish they would increase the viewing time from 24 hours to at least 48 hours and also offer a monthly subscription.
This would provide two benefits. Hopefully I could watch more movies at a reduced rate and would allow me to download movies that I think I might want to watch. This way I wouldn't have to wait on the download if I decide I want to watch the movie.
If possible being able to download the movie before purchasing and only paying if you decide to view it would be great (I think DirecTV or someone else is doing something similar). This way I could always have three or four movies ready for viewing. Just like tonight if we could have sat down and watched a movie they would have gotten an additional rental. One my wife wanted to watch plus the one I was willing to wait on.
It's still early in the online movie rental game and I'm sure there will be a lot of changes. Hopefully a subscription plan (perhaps two or three) and pre-purchase downloading will get a turn at bat. -
Personalization Scheduling Engine does not start -- Bug?
Hi there. I don't know if it's the correct forum to post my question. If I'm wrong I ask you to redirect to
the correct one.

environment :

My problem focuses on Personalization. I advise that in my developing environment I've not got any problem.
So , I've installed Oracle AS Personalization without wornings. I've created RE,MOR and MTR schemas as the
procedure dictates. Problem's that Personalization Scheduling Engine does not start. It should start
automatically but It didn't. So I tried to start it by hand following "Oracle Application Server Hi there.

Personalization Administrator's Guide 10g(9.0.4)". Specifically , when I try to start the scheduling engine
with the command "execute OP_START_ENGINE" in the MOR schema I obtain an error linked to DBMS_JOB.run()
method. Digging deep into the Oracle alert log file I found this brief linked to the error executin the
script :
Thu Apr 14 17:57:28 2005
Errors in file E:\MetadataRepositoryHome\admin\asdb\udump\ORA01860.TRC:

ORA-06512: at line 1
So as the main error is "NumberFormatException" , I executed reverse engineering decompiling two Oracle
classes , just to know the origin of the error :
oracle.dmt.op.util.messagelog.MessageLog and
oracle.dmt.op.workflow.SchedulerWorkflowClass
After simple tracing I think I reached the origin and I shocked myself to see it!! The problem starts in the
main_method of oracle.dmt.op.workflow.SchedulerWorkflowClass, i.e. :
private void main_method()
throws Exception
String event_msg_args[];
traceMsg += "Start";
moduleID = "SchedulerWorkflowClass.main_method";
traceMsg += "-executionContextID";
executionContextID = MessageLog.getExecutionContextID();
The problem resides in the getExectiongContextID() method of oracle.dmt.op.util.messagelog.MessageLog class.
Code of this method is this :
public static long getExecutionContextID()
String hostIP = null;
try
InetAddress host = InetAddress.getLocalHost();
hostIP = host.getHostAddress();
catch(UnknownHostException ex) { }
StringBuffer buf = new StringBuffer(20);
if(hostIP != null)
for(StringTokenizer st = new StringTokenizer(hostIP, "."); st.hasMoreTokens(); buf.append
(st.nextToken()));
buf.append((new Date()).getTime());
String tmpString = buf.toString();
String idString = tmpString.replace('?', ' ');
idString = idString.trim();
int len = idString.length();
if(len > 19)
idString = idString.substring(len - 19);
long id = Long.parseLong(idString);
return id;
Simply , code obtains IP address of the Host , concats it with the current time and if the length of the
result string is longer than 19 it obtains substring of (len -19) length!! I think , Oracle programmer
thought to prevent NumberFormatException with the control "if(len > 19)
idString = idString.substring(len - 19);"
but that's strange , very strange!! In fact , in my case(with my IP Address 160.97.*.*) , method outputs
NumberFormatExceptio 'couse long "id = Long.parseLong(idString);" is not able to convert the String
"9756161113494248343" to java.lang.Long!!! 'couse it exceedes maximum value ( 2EXP(63)-1)!! So , I think
it's bug but I don't know how to solve it!! Problem's in method's semantic. It should control that the
String it creates is lower that the maximum value allowed for a long , not its length lower or equal 19!!!
I mean , I cannot modify Oracle Java Class file.
With kind regards,

Can no longer return to iOS app in AIR 4.0 Beta
Is it me or is it no longer possible to return to an iOS app in AIR 4.0 beta? An app I just compiled restarts every time you launch it. No such problem in AIR 3.9.
Just yesterday I saw a problem where going to the home screen and back would either crash the app or would leave it in a frozen state. It only happened if by that time I had been via a part of the app that played an animation that used stream audio.
Might you be seeing the same kind of thing, where you can go in and out of your first screen, but get crashes or hangs when going from another screen?
I didn’t log a bug yet because it’s a hard problem to narrow down, because the crashing happens when you return to the app, and so doing a debug session won’t help, the session closes when you go to the home screen. -
Return arrow no longer available
I no longer have a return arrow showing on any of my displays. I used to have it and it no longer shows up. It's very inconvenient. Why is this and how can I get it back?
In the Safari menu at the very top of the screen,
choose View > Customize Menu Bar.
Pick the back arrow, and drag it onto your menu bar.
Hope this helps. -
Warning this is very long code but i need help to see if I am on right trac
I have done all the following code myself and it is the buisiness layer for my application. I have tried to follow recommendations on previous posts and I would like to be told where I can clean up my code and how? This is not complete and it looks very long to me but I need help in order to be better. There are 4 button vlivks and I have not completed them all. The criteria for application is that phonebook will accept new entries if they have names surnames and phone numbers that are not longer than 10 characters for display purposes but can change this. No duplicates are allowed. No editing of a existing entry must lead to a duplicate entry either. No new entry or edit may result in a new contact having no phone numbers.

Hi,
Im formatting a Date using a SimpleDateFormatter and it always add 19:00h to the time....
SimpleDateFormat sdf = new SimpleDateFormat("h:mm:ss", getLocale());
Date d = new Date(0);
sdf.format(d);it gives me 19:00:00 instead of 00:00:00
I think this is a matter of time zone... like if the hours added to adjust time to my time zone were always added to the time! What i want to do is simply display a number of miliseconds in h:mm:ss
thanksThanks i used a similar formula and it does the job
// The method i use

long ss = (milliseconds-(hh*(1000L*60*60))-(mm*(1000L*60))) / 1000L;
return leftZeroFillInteger(""+hh, 2)+":"+leftZeroFillInteger(""+mm, 2)+":"+leftZeroFillInteger(""+ss, 2);
// I also put here other methods i already have and i used to format the final string

PageDef operatingBinding is not visible or returning null
Hi,
I have an ADF application with taskflow which contains a page fragement which has some methodAction bindings in its pageDef.
I dragged this taskflow as a region in a Webcenter Portal application project page which has a pageTemplate. When that page opens, it opens fine by initializing the page which involves invoking some methodAction bindings.
After the page got loaded, I click on a button, this again requires methodAction bindings but this time that operationBinding is returning null. so, I am not able to invoke the method.
I am getting the operatingBinding in my managed bean as below. operatingBinding is fine while loading the page (init method) but it is giving null when I click on any button in the page after page load.
OperationBinding operationBinding = getBindings().getOperationBinding("getPersonId")
public BindingContainer getBindings() {
if(this.bindings == null){
FacesContext fc = FacesContext.getCurrentInstance();
this.bindings = (BindingContainer)fc.getApplication().evaluateExpressionGet(fc, "#{bindings}", BindingContainer.class);
return bindings;
I dragged the same taskflow to an other ADF application and it worked fine before and after loading the page. I do not understand why it is not working in portal application. But it is nothing to do with Webcenter I believe. I just wanted to know if anyone faced this issue before. Please give some pointers if you have any.
