Does the logging API provide "Asynchronous File Handler", like log4j ?

Hi,
One more question about java.util.logging:
Does sun provide a standard "Asynchronous File Handler", equivalent to log4j AsyncFileAppender ?
The idea is, logging requests are placed into a queue, which is being consumed by a dedicated logging-IO thread.
Thanks.

it's a shame, really. the Logging API was blatantly inspired by Log4J, but it's just such a poor cousin in so many ways...

Log API: daily roling file appender?

my task is to replace Log4J with the JDK 1.4 logging API. how can i configure the logging to have a FileHandler that does daily rolling (like Log4J DailyRollingFileAppender) and offer a a date pattern for the file name (like Log4J DatePattern)?
the result should be that each day, a new log file is created with the old files having a datepattern in the file names.

Well, i wrote my own now, that supports time rolling (day, week, month, year) and later additional rollings. here's a start:
import java.io.*;
import java.text.SimpleDateFormat;
import java.util.*;
import java.util.logging.*;
* File handler that supports different kind of rolling than java.util.logging.FileHandler.
* Supported rolling methods are: by date (day).
* <p>
* Example of entries in the logging file (system property "java.util.logging.config.file"):
* <p>
<table align="center" bgcolor="#ddddff" border=1 cellpadding="10" cellspacing="0"><tr><td><pre>
logging.RollingFileHandler.level = FINEST
logging.RollingFileHandler.prefix = MyApp_
logging.RollingFileHandler.dateFormat = yyyyMMdd
logging.RollingFileHandler.suffix = .log
logging.RollingFileHanlder.cycle=day
logging.RollingFileHandler.formatter = java.util.logging.SimpleFormatter

Where does the logging in RDBMSRealm go --and-- are some JavaDocs missing?

I see that a LogOutputStream is created in the example
class RDBMSRealm, but where do all of the log
statements go. The LogOutputStream is created as:
log = new LogOutputStream("RDBMSRealm");
but I do not see and file called RDBMSRealm and/or
I do not see the log statements on stdout.
BTW, I do have logging set to the most detailed
level (Info) from the console if this matters.
Also, are there some JavaDocs missing from
Weblogic's Reference website at
http://edocs.bea.com/wls/docs60/javadocs/index.html
LogOutputStream is an example. I do not see the
class when I select the package
weblogic.logging.
Where is it?
Much Thanks
Bill Ralenkotter.

Thanks Terry,
Sorry, I should have mentioned that I am using WL6.0.
Does anyone know what I need to do to get the RDBMS Realm log to start on
WL6.0.
About the missing JavaDocs: Also, if I am doing development using these
classes I still do not
understand why they are not on the 6.0 refernce site!
About the missing JavaDocs,
I see java docs for a lot of classes, but what document do I use that
helps me to understand the entire framework? The Programming
Weblogic Security does give this information.
Example question: how do I get a reference to the realm to create
users? Should I even be doing this?
Thanks for your help.
Bill.

If you are using WLS5.1 you much set the property
weblogic.security.realm.debug=true
then this information will be sent to stdout. This is set to false by
default, as there is a lot of information, and it is a big performance
hit.
I think weblogic likes to avoid some of its APIs being public, which is
annoying at times, but probably reasonable

Does the iMessage protocol provide for "online status" indication?

In iChat, I could set the online status of my AIM account ("Available", "Away", etc.).
Does the iMessage protocol provide for "online status" indication?

HI,
Messages Beta can do the same indications for the older style iChat Buddy List the same as iChat does/did.
The iMessage Login (the "Account" in the Messages Menu > Preferences > Accounts that deals with sending iMessages to iPhones and iPads) does not have the same indicators.
What it does do is indicate the options in the "To" spot for the Name that is currently shown there.
To explain that a bit further.
When you click New Message the Blue Plus icon appears
You can select Contacts from this list and navigate to a Contact in the Address Book
Once you select a Contact their Name is in the "To" spot
If you now click this it becomes a Drop down and the iMessage details they have are marked with a blue Speech bubble.
IF you select an iMessage Contact this way and they are Off Line the name will go red.

Does the iPod nano support MP4 files?

Does the ipod nano support mp4 files?????

Hi uptight,
Yes, the iPod Nano does support MP4 files.
You can find more information about the files the iPod supports here: http://www.apple.com/ipodnano/specs.html
You can convert many videos right from iTunes. This article: http://support.apple.com/kb/HT1211 will walk you through the process with sample files.

Does the Ipad2 support .epub (ebook) files?

Does the Ipad2 support .epub (ebook) files?
And: does it support websites built with flash?

Epub boooks are supported. There are a number of different ebook apps, and generally books are locked (due to digital rights management systems) to the app/retailer that they were bought from e.g. iBooks (Apple), Kindle (Amazon), Barns & Noble, Nook - so won't be able, for example, buy a book from Amazon and read it it iBooks, you'll have to use the Kindle app.
Flash is not supported on any iOS device (iPad, iPhone, iPod Touch). Some apps claim to (e.g. Skyfire) but judging from the reviews the results are varied. More info on why it's not supported here http://www.apple.com/hotnews/thoughts-on-flash/

Hi
We are looking for a software which converts SWF to MP4, we found many software which does the job but issue is file size is not optimize.
We found Adobe captivate 6 which gives optimum quality with good output but thing is we do not have batch process in captivate 6. so we request you to create a plugin or give a best option which have batch render quality and optimize in file size,

Captivate is e-learning development software not a dedicated video convertor, you are better off trying something like Adobe Media Encoder or Super.

Why does the Java API use int instead of short or byte?

Why does the Java API use int if short or even byte would be sufficient?
Example: The DAY_OF_WEEK field in Calendar uses int.

One of the point is, on the benchmark tests on Java performance, int does far better than short and byte data types.
Please follow the below blog talks about the same.

What Does The Log Message "Rejecting update: Lease..." Mean?

I use RelicatedCache and TransactionMap on Coherence 3.4.2.
I saw "Rejecting update: Lease..." message.

I found a Note 1065352.1, but the message is little differnt...
Note 1065352.1
"What Does The Log Message "Rejected update: Lease..." Mean?"I'd like to know following 2 points..
- What does "Rejecting update: Lease..." message mean?
Do thsese messages have same meaning?
- My application didn't catch any exceptions, and
"CacheFactory.commitTransactionCollection" returned true.
So this "Rejecting update: Lease..." is not a error message, right?
(Does the transaction commited successfully?)
Thanks in advance.

Does the latest version of Numbers have anything like Excel's goal seek?

Does the latest version of Numbers have anything like Excel's goal seek? I frequently use goal seek to solve non-algebraic equasions for an unknown. Thanks.

I went through the installation where the bar shows the percentages downloaded and installed. Once it shows 100% it asks me to click Finish. I do. Then I go to yahoo to check and it continues to show that the plugin is missing and that I need to download Adobe Flash which I thought that I just did. Am I missing something in terms of installing??

Apple isnt here. this is a user based forum for technical questions. The solution is to restart, reset, and restore as new which is in the manual after that get it replaced for hard ware failure. if your within your one year warranty its replaced if it is out of the warranty then it is 199$

Does the Communications API work with Studio 4

I just installed Studio 4 along with the JDK. The Java version that I am running now is:
java version "1.4.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_02-b06)
Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)
Running on MS XP.
The Communications API seemed to work just fine on JDK 1.3 with Forte 1.0.
I installed the Comm API as instructed and set my ClassPath:
CLASSPATH=D:\PROGRA~1\s1studio_jdk\j2sdk1.4.1_02\lib\comm.jar;D:\MyProjects\java\GarxFace
A call to:
Enumeration portList;
portList = CommPortIdentifier.getPortIdentifiers();
does not yield any ports at all.
Stranger yet, if I use the auto complete feature in the editor. For example if I type: m_PortID. then no members of PortID show up.
But the code compiles just fine.
Any idea what is going on?

First I found the reason that the auto complete was not working. I had to mount the comm.jar file (you did not have to do this in Forte 1,0, just set the classpath). I thought that I had done that. That is the problem when you work late. ;)
Here is a eexcerpt that I found on a search in another post:
Copy javax.comm.properties to your <JDK>\lib directory.
C:\>copy c:\commapi\javax.comm.properties c:\jdk1.1.6\lib
The javax.comm.properties file must be installed. If it is not, no ports will be found by the system.
Notice it says that "javax.comm.properties file must be installed"
javax.comm.properties is indeed installed in my JDK lib subrirectory, but it is almost like it is not being found.

Why does the Palm Centro save my files as .php files?

Okay so I've been trying to download files from the internet and save them on my Centro. When I click on the link to download it, it shows the file as a .doc file which is good because it's a microsoft word file. but then when I actually click "Save", the file changes to "download.php" and I can't open the .php file on my Centro. So my question is, Why does the .doc file change to the .php file? And more importantly, how can I save the .doc file without it changing to .php?

Hi.. Welcome to the Palm forums. Any Palm device is going to convert any file saved to it to the format it needs to be able to read it. For .doc files, word documents, you need docs to go which comes with your centro for free. Docs to go 10 is required for office 2007 and is available free for a centro, go to www.palm.com/us/support select downloads under support & downloads then select a centro and you will see a link for bonus software on your cd. Find docs to go, download it to your computer and install. Then sync which will update and/or install docs to go 10 on your computer and your centro. Once that is accomplished if you want to put a office file on you centro you open docs to go on your computer, add in the office file and sync. After that if you update the file either on the centro or on the computer then sync both files will end up the same after the sync.

How does the ActionScript API, Eclipse IDE, Flex SDK, Cygwin & Flex Builder all communicate??

Whats up Everyone! As you might've immediately recognized from the title of this thread I'm new to developing apps with Flex.....
If I've succesfully set up my development environment (Flex SDK, Eclipse IDE, JAVA SDK, Apache Ant, Flash Player, etc.....) & checked out the source code using Subversion, can I start developing my app using the ActionScript 3 API using Eclipse? & how do those different SDK's & programs communicate? How should they be setup?

If you're willing to buy into the FlexBuilder way of doing things, that's probably the way to go. In this case, you don't really need to worry about anything except FlexBuilder (at least for a while). I don't really have any experience in setting up a project with a server component (I always set 'server type' to 'None' and configure this manually), but other than that, the experience has been (fairly) smooth, and I'm someone who's pretty heavily biased towards the command line. FlexBuilder takes care of most of the Flex compiler options, tracking different SDK versions (I have three different ones installed), offers code completion and navigation tools, etc.
To get some of the terms straight (I'm not sure how familiar you are with these, since you just threw them out there--pardon me if I'm being patronizing):
* the ActionScript API: the function and class definitions built into Flash Player (fl.*) and the Flex standard library (mx.*)
* Eclipse: a Java IDE, the core of FlexBuilder
* Flex SDK: the Flex standard library, the mxml and compc flex compilers, some ant tasks for build automation, etc.
* Cygwin: this does not really have anything to do with Flex specifically, as far as I'm aware--it's a *nix emulation layer for Windows
* FlexBuilder: the Flex IDE from Adobe, built as a plug-in to Eclipse
FlexBuilder is available in standalone (i.e., pre-bundled with Eclipse) and plug-in versions. Both versions include the SDK. If you're just starting out, I would suggest a FlexBuilder standalone trial, and follows some tutorials out there (or, really, just chose "new Flex project" and explore). In this case, you don't really have to worry about installing or configuring anything else to get started.
Note also that for the upcoming Flex 4, FlexBuilder has been renamed Flash Builder (but I would stick with Flex 3.4 or 3.2 right now unless you really likethe bleeding edge).
