Need material on Java Internals
Hi,
I need to learn how the JVM works and how a java program is executed in a JVM.
Can anyone provide me reading material on this topic.
Thanks

Need Information About Java Platform Overview For Manager (WJTB-310)
Hi, My name is Jeffry. I need information about Java Platform Overview For Manager (WJTB-310).
I need Information about table of contents, how long it takes to study that training (approximately), how many chapters are in that training, minimum Internet connection speed to access that training, and everything you know about WJTB-310.
Is there a synchronized audio in WJTB-310 ?
Is there a video streaming in WJTB-310 ?
Can I receive a certificate for any web-based training ? especially in WJTB-310 ?
Is there a programming language material in WJTB-310 or just an overview ?
Sorry for asking to many question
Thanks
Jeffry Kristianto YanuarI thought I'd give you a response even if I can't answer your question completely. (I think we ought to start a separate thread entitled "How do you get any replies on this forum???") Here is what I have been forced to do. I introduced some JavaScript on the web page that contains the applet I want to be run. The sole purpose of the JavaScript is to detect which platform the client is on. If it's not MacIntosh, then I have JavaScript write the <object><embed> tag used by the Java plug-in. It it is MachIntosh, then I have JavaScript write the regular <applet> tag and let the Mac browsers do as best they can. With mixed and disappointing results. Netscape 6.2 crashes with a lot of applets. IE 5 brings up the applet okay but certain Swing components aren't displaying properly. The MacIntosh I've been testing on is version 9.1. I'm trying OS X tomorrow.
Why don't you send a reply to my query under the Java Plug-in Forum--from aronsz, dated 06/11/02--if you have some more info by now. I sure would appreciate it. -

Can anyone suggest me a good book on Java Internals.
If my explanation is too lengthy,I apologise for that.
1)If I say Iam instanciating an Object
2)or using Collections,I need to know how these are exactly happening inside the JVM.
Though I have 1 year of experience in Java,I need to know more elaborate on that.Can anyone suggest me a good book or link on this.
Regds,
VidhyaCan anyone suggest me a good book on Java Internals.You mean VM specifications?
http://java.sun.com/docs/books/vmspec/2nd-edition/html/VMSpecTOC.doc.html
If my explanation is too lengthy,I apologise for
that.What if it is too short? :p -
Please tell me which is the best book for learning Java Internals -
JVM
Java Class File details
Execution details of Java Program, etcThis was all the info I needed to write a disassembler.... but it's far from easy reading... more of a reference than a developers guide.
http://java.sun.com/docs/books/vmspec/2nd-edition/html/VMSpecTOC.doc.html
But there seems to be a few books out there if you do a google search of
"java virtual machine book"

Explicit cast needed to convert java.* to to oracle.*
Hello,
I am trying to compile and run the following JSP but keep getting the "Incompatible type for = Explicit cast needed ..." error. The JSP and oracle procedure code are as follows:

cstmt = con.prepareCall("call eaicl_p_requirement.open_rule_dtl(?,?)");
^
I'm not sure how to fix it. I also need to pass the p_product_id parameter to the procedure.
Hope someone can point me in the right direction. Thanks.Here's how you do an explicit cast:cstmt = (OracleCallableStatement)con.prepareCall("call eaicl_p_requirement.open_rule_dtl(?,?)");

plugin-container crashes and hangs many times daily all my time eaten up by upgrading too frequently to new Ffox versions, only to find that I must then spend a whole day jumping thru hoops upgrading almost all of my add-ons too.
I now find, to my horror, that the hideous virus-magnet IE 8 is needed if I want to surf at a reasonable speed and not spend all day dealing with Ffox new versions' Known Issues. Only good thing I have seen about ver. 3.6.15 is slightly better launch-times. Since 3.6 cane out, I must spend 10 minutes just waiting for Firefox to load and give me a browser screen. Help! I love you guys, but your core browser developers need to have better comms with the Javaa/flash/Adobe and other must-have add-on people! And PLEASE fix all these "plugin-container" crashes and hangs I get, that lock my machine for 10-15 min at a time. Not everybody has 16 gigs of RAM, you know! I think the "plugin-container" running as a separate process idea might need to be COMPLETELY re-engineered! YOU CAN DO IT! LET'S GET BACK TO LEAN AND MEAN, and not bloat ourselves off our hard-won User Preference / great security pedestal with the kind of feature-creep that IS DEMOLISHING IE's slave-userbase with the hard-won advanced-user preference for Firefox
and our core values. FAST-LEAN-SECURE.
Where have they gone? I LOVE Firefox
and all it stands for! Let's not trip
over our own features here. Already I
see SeaMonkey and leaner, faster
browsers hot on our heels, THIN and
FAST! Firefox doesn't need to integrate
with EVERY thru-the-browser media tool
on the planet! I've been writing code
since 1968, and I can't imagine how a
lesser-experienced user (that code
should be written for) could possibly
have navigated all the side-upgrades
and Known Issues to make Firefox run as
sweetly as it used to! He'd just give
up when he finds he has to separately
find and install the EXACT 3rd-party
version that Firefox needs for its
newest release: things like a new Java
runtime environment, and hunt down and
correctly install ALL the Flaming-Phox-
compatible buggy plugins from half the
browser-media warezmakers on the
PLANET! He'd give up halfway thru trying to navigate to, D/L, and install
what he needs from Oracle Java, Adobe,
Flash, media players and their codecs,
etc etc.... WRITE FOR THE NOOBS! As it
is, I have invested 2 full workdays in
just keeping your last 2 quick releases
happy. And having another release spaced only 3-4 days apart from the
last- well, that just doesn't fly.
Better to release a hotfix or patch that a user can set FFox to automatically D/L and self-install on
schedule. Just look! Now you've got me
talking like that lawbreaking swine
Gates! We want to keep on absorbing
the average-user center and take it ALL
away from him, not go on feature,
plugin, and upgrade-bloating the best
browser EVER!
You're facing choices that can kill
us! PLEASE DONT BLOAT! AND PLEASE ONLY
RELEASE A NEW VER WHEN YOU CAN REALLY
GET RID OF SERIOUS PROBLEMS AND MAKE
HER FASTER AND LEANER AND BETTER UNDER
THE HOOD! Already the Noobs are getting
mindlessly scared when you talk about
"fixing a Security problem"- really a
minor issue that SHOULD be taken care
of by their antimalware solution- in
the Release Notes splash screen they
get on install of a new ver! Thanks, my
friends, for all your work, and YES I
WILL sit here all day trying to find
the add-ons that need to be selected,
downloaded, and upgraded from 10
different 3rd-party sites who are
fighting our browser, not dancing with
it! DON'T EVEN LOOK Evil! But I have
to confess that at this point, Gates-hate is all that keeps me on
these all-day new-release tasks. Even
my best techs are starting to advise me
to install SeaMonkey or another of the
newer, thinner browsers... or just stop
upgrading Firefox and roll it back to
when it was sharp, fast, and lean! Look
at all the users wanting to go back to
3.6.13 or earlier and looking for archives of old versions. THANKS AND
GOOD LUCK! I'LL DIE BEFORE I GIVE UP ON
MY BELOVED FIREFOX!
-The CRASHMAN, ATTORNEY AT LAWThanks! I've already used the built-in plugin checker but it gives very vague answers like (research this" and update this" all of which I did, starting with Java and Flash, Adobe Reader, Shockwave, 100% reinstall of Java newest ver. TWICE- but FFox keeps reporting that I only have the FORMER version installed, although when I go to Java console or Check the Flash executable at the MFR's site, there is NO doubt that the updates were successful!
But the browser just seems to refuse to acknowledge the update!
And I don't HAVE 6 hrs/day at the 'puter just to play with add-ons
and plugups. So I'm going down the line now, ripping out extension
programs and replacing/reinstalling/updating the plugins one by
one- even went to M$ to get advice on THEIR For-Firefox ActiveX
stuff. No dice so far. And yeah, The plugin-container WAS made so
that a plugin, add-on or I guess extension app failure wouldn't take
the whole FF browser down with it if the 3rd-party ware crashed. It's supposed to shake it off and go on, kinda like how XP sometimes
restarts Explorer (not the IE browser) so I don't have to reboot the
whole sys.
That was the foundation of my remark about stepping back and
re-engineering the whole "Plugin-container" idea, because it seems
to do more harm than good. Maybe that's why the Firefox core
engine won't recognize my upgrades- for example I TWICE installed the Flash update to 10.2.xx (latest ) and the Flash Mfr's
site verifies my upgrade as a successful 10.2, but Firefox plugins
check say I have a 10.1, the old one. What gives here? The sneaky
PLUGIN CONTAINER, METHINKS!
Now I'm disabling things on the Extensions Apps list, thinking
that might help, like disabling my video downloader and other
download helpers/managers... and I notice that there is a LOT of
Java stuff in there too as well as in the blue Lego Plugins List... and
in the past the FFox always told me if a new version of Ffox was
incompatible with any older 3rd-party app Extensions and notified
me QUICKLY if something I had in there was Outdated. I'm big on
using the neat-o "find updates" button at the bottom if that happens, and usually get a newer version right away. The prob
really lies in the Blue Lego Plugins and their new Container, I
believe.
So Ill still keep Plugin-innin' away! Will post here what success I have! (OR maybe M$ is deliberately sabotaging our ActiveX-cripple
mess as it loads!) Thanks for the suggestions a37271!
FIND UPDATE...FIND UPDATE.. ALL OK..ALL OK.....
"Open the Plugin Container Bay Doors, HAL! That's an Order!"
"I'm sorry Dave.... but I can't do that...."

ASA 5505
ASA Version 9.0.(2)
Suddently on the webvpn Interface when i click on my web bookmarks (and java launches in browser) i get this fail in Chrome and FF 'It has take a while for SSL VPN Relay til load. You need to verify Java is enabled in your browser' and nothing happens...
Java IS enabled and running. Tried this in both 7.45 and 7.51
No problem in IE 11 and java 7.45 and 7.51
I've googled alot but have not been able to find any suggetions
Hope you have a solution
Best Regards.Any resolution on this? Firefox/Chrome my cifs work but smart tunnel RDP doesn't, and in IE my shares don't work but RDP smart tunnel does....
Cisco, if you're not going to do something good, just don't do it. The SSL VPN is a hack job. -
I have a brand new iMac, Retina 5K, Yosemite 10.10.1, with Java Version 8, Update 25, however, I still get a window when I open Adobe Photoshop CS5, that indicates that I need to install Java SE 6 Runtime. Any suggestions?
Java should be downloaded directly from Apple:
Java for OS X 2014-001 -
....desperating trying to install itunes 10.7, but it asked me to install Mac OS X 10.6.8. I did, but then it said that I needed to install Java for Mac OS x 10.6. I did that and now it keeps saying 'this update requires Mac OS X version 10.6??
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
Snow Leopard General Requirements
1. Mac computer with an Intel processor
2. 1GB of memory
3. 5GB of available disk space
4. DVD drive for installation
5. Some features require a compatible Internet service provider;
fees may apply.
6. Some features require Apple’s MobileMe service; fees and
terms apply.
Actually, you cannot download Snow Leopard. You downloaded a Snow Leopard updater. -
Keep getting an error message that I need to download Java Runtime Environment
I have a one year old iMac and just downloaded OS 10.10 (Yosemite). Since doing this 2 weeks ago, I keep getting the same error message telling me that I need to download Java Runtime Environment in order for the webpage to run properly. I have downloaded, installed and checked the installation 3x already. The message goes away for a day or two and then returns.
Any idea on what I have not done correctly or need to do further?
Thanks for your he1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Bug: BLZ-152-lcds custom Date serialization issue - need to add java.io.Externalizable as the first type tested in AMF writeObject() functions
QA: Yes - please check that the fix is working with AMF3 and AMFX and you can turn on/off the fix with the config option.
Doc: No
Checkintests: Pass
Details: The problem in this case was that MyDate.as was serialized to MyDate.java on the server but on the way back, MyDate.java was serialized back to Date.as. As the bug suggests, added an Externalizable check in AMF writeObject functions. However, I didn't do this for AMF0Output as AMF0 does not support Externalizable. To be on the safe side, I also added legacy-externalizable option which is false by default but when it's true, it restores the current behavior.
