Persistence and hibernate (and maybe XFire)

Sorry didnt know in which forum to post this.
I have a very weird problem. We are using Springframework with XFire and Hibernate. All Database rows are implemented as Persistence Objects for Hibernate. So far it works well.
We transfer this persistent objects over XFire between several Services which works too. But as soon as there is "Boolean" (NOT boolean) type involved the value stored in Boolean variable ist lost after transferring over XFire. So at the target service always null arrives as variable value.
It's important to note that this strange behaviour only applies to persistence objects, but not to normal objects transferred over XFire.
Maybe someone encountered this problem too and has a solution for it :(

as mentioned already: difference between 2.6.35.6 and 2.6.35.7 in one patch for Xen:

Xen: fix typo in previous patch
Correctly name the irq_chip structure to fix an immediate failure when booting
as a xen pv_ops guest with a NULL pointer exception. The missing 'x' was
introduced in commit [fb412a178502dc498430723b082a932f797e4763] applied to
2.6.3[25]-stable trees. The commit to mainline was
[aaca49642b92c8a57d3ca5029a5a94019c7af69f] which did not have the problem.

so you may as well stay with 2.6.35.6 if you have less problems with it but your is not related to a bug introduced to 2.6.35.7
also I don't have any issues with 2.6.35.7 so maybe there is something about your config?

Java framework/toolkit for POJO, database persistence and XML

Hi all,
I've been wondering if there's a toolkit or framework for developing Java program (could be standalone Java program, EJBs etc.)
I surfed around casually and found some but there isn't any detailed description of what and how each framework/toolkit does. So I hope to ask around if you've anything that you have used before and would like to point to me to look further.
Given the huge number of open source toolkits, libraries and frameworks out there, it can be quite confusing as to which one is more suitable for me. Also with Sun's move into JDO and Java Persistence API, things become more messy and complicated - there isn't any clear leader in this area and things are starting to change with the inclusion of JDO which seems to be the future standard persistence API to use.
So far, I've only worked with Hibernate for database persistence before. So I'm wondering if there're other options such as Hibernate with XDoclet, Castor and Spring framework etc. that can easily transform Plain Old Java Objects (POJO) -- hopefully using Java Reflection w/o using mapping XML files like in Hibernate -- into SQL for database persistence and XML text data and vice-versa. The current problem is that I've been spending tons of time writing code to transform data in Java objects into XML (using my own format) and also doing mapping files for Hibernate.
I am hoping for something simple like:
Object o = new Object();
o.setProperty = "something";
String xml = o.toXML(); // Convert object to XML text.
o.save(); // Save to database.
// The reverse: Parse XML into object and load from database
Object o = new Object();
o.fromXML(xml);
o.load();
// Properties should be initialized from database or XML.
Anything similar to this out there?

Hi,
Just to share what I've found after surfing a bit more on this issue to promote more discussion on this area.
For mapping of Java objects to XML, we can try looking more at Castor and JAXB.
For database persistence to/from Java objects, look at Hibernate and JDO.
There is this Hydrate project (hydrate.sourceforge.net) that I do not know where it fits in still. But it is supposed to do data transformation and mapping between Java objects, XML and database representation.
Fyi.

Can I carry out the persistence and ORM tasks using EclipseLink?

Can I carry out the persistence and ORM tasks using EclipseLink (without TopLink or Hibernate) ?
Is the EclipseLink a free tool and no license fee?
How about TopLink Essentials?

However, Oracle does redistribute EclipseLink as part of the Oracle TopLink product and therefore customers are able to access support for EclipseLink through Oracle support.

I seem to have at least two, and maybe four, iCloud accounts, across my iPhone, my iPad and my MacBook Pro. Can I combine them into one iCloud account? I have been able to log into what appears to be three of the four iCloud accounts I have. Two of them seem to be remarkably similar, and one appears to be only for my MacBook.I think I know which one my iPhone is backing up to, as I successfully restored from a back-up last week. The fourth iCloud account I can't access via password or security questions. Any advice would be much appreciated.
Thanks.

I am trying to use the trial creative cloud software on a PC windows 8.1 - I've downloaded and removed Photoshop CC 2014 two times - every time I open the file it says there is a problem and it shuts down and closes. I can open indesign and maybe other apps but photoshop no. Any ideas?

I don't think I can access the crash report? Excuse the ignorant questions I'm about to make am a relative tech novice.
Soo - as mentioned every time I open photoshop it crashes - it just says there's an error and the program will shut down and if there's a solution windows will notify me. Then nothing...
I've tried to look in photoshop files for the detailed crash report & the system event viewer but cannot find a file with those names. I've also looked in the windows files for files with those names but cannot find them either - so I don't know where to look.
Any guidance would be great.

Spry security (and maybe ajax security)?

Hi there,
I've been used Spry for several sites until now, later i
realized that we can easily request the XML (if use XMLDataSet) by
parsing variable to url directly which would be like this:
http://www.example.com/data_generator.php?var1=x&var2=y
This way was too vulnerable, but in other hand it handy for
developer to ensure their request was acceptable and XML can be
generated.
Is there any way to prevent this? At present i use a session
authentication method for securing XML request, so only user who
have privileges can do the request, otherwise else would fall into
front page (and maybe login page)
That was case if we use dynamic XML (server-side XML
generation), how if we use static XML and no server-side
programming language at all?
Thanks,
Dels

Personally I would use a .php extension for static XML files
too,
leveraging the existing session authentication mechanism. The
overhead,
compared to use a .xml extension is very, very small.

If you used icloud for your contacts and calendar then you should have no problem. They will all come back on the phone once you put the icloud user name and password in. Itunes does not store the contact information except in a backup file and if you were backing up using icloud you can use that backup to restore with.

Hi Mehmet,
thank you. I could not answer on friday, was not at office.
I tried according to the instructions of oracle ( http://docs.oracle.com/cd/E17236_01/epm.1112/pr_studio/frameset.htm?data_connection.html ). See comments:
To create an Essbase data source connection:
1. OK
Select Connection on the main SQR Production Reporting Studio screen.
The Create Data Connection wizard is displayed.
2. OK
On the first page, enter a name to identify the data connection.
For example, you could enter Essbase to identify a connection to an Essbase data source.
3. OK
On the second page, select DDO to identify the data source provider.
4. NOT OK. The messages shown: "Unable to start the JVM. Ensure that the JRE section of the SQR.INI file contains the correct directory. (4)"
"Unable to erad DDo Registry.Properties file. Check location and accessibility, an that the sqr.ini DDO pathvariable settings are correct (DDO.3)."
On the third page, select an Essbase data source.
The wizard displays the available registries and data sources.
Seems some setting problems. We would check that. Any suggestions to that error??

Css11501 Whats the difference in persistence and stickiness

css11501 Whats the difference in persistence and stickiness

persistence is an HTTP concept.
With HTTP 1.1 you can now have 1 TCP connection for all your HTTP requests.
With this solution you reduce time by not having to open and close TCP connections for every request.
It is sometimes needed to break persistence to guarantee a better load sharing between the servers.
This is the case when multiplie users use the same proxy server.
The proxy would generally open a persistent connection and use it for all the requests from all the users.
Stickyness is a loadbalancing mechanism to guarantee that every TCP connections are sent to the same server.
You can do stickyness based on source ip, or SSLID, or a cookie, or ...
Stickyness is required when you have a website saving information about a user session [ie: a shopping basket].

Plugins usually are installed externally to Firefox. However, you can disable them in Firefox so that Firefox does not use them.
SearchReset is supposed to automate the task of resetting certain preferences, but you still can edit them manually if necessary.
'''''Address Bar Search'''''
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''keyword''' and pause while the list is filtered
(3) Right-click '''keyword.URL''' and choose Reset. This should restore Google as the default for address bar search.
Does that work?
'''''Search Box'''''
Usually it works to choose your preferred search engine from the drop-down. To remove an unwanted search engine plugin, usually the Manage Search Engines... choice at the bottom of the drop-down takes care of it.
Do either of those work?
There might be another way to hijack that search box; I think some of the other frequent responders probably are more familiar with it than I am.

Hm, it seems the new website has obscured the option for purchasing the smaller monthly accounts. You can purchase it here. Adobe Connect | Meetings.
If you need more than the 25 per meeting limit, you can reach out to a reseller of your choice that covers your area, Adobe Connect | Strategic Partners.

I am officially through the roof. And maybe halfway to the moon.

So, more than two months ago, I downloaded 7.5, hoping that I would once and for all be able to access the store again (because of 7.4.3's 11333 error), only to discover that it corrupted my sound card. As soon as I restarted my computer after I installed my iTunes 7.5, the "Found New Hardware" box popped up, trying to install something for my NVIDIA Audio Device. It said it could not be installed properly. I didn't think anything of it, until I opened my iTunes and it said it detected a problem with my audio configuration. I realized that my computer no longer produced any sound. Nothing. I was pretty confused at this point. I asked for help online, but nothing helped. I tried uninstalling and re-installing quicktime but that did not work.
However I COULD connect to the store, which made me sort of happy. I redeemed an iTunes card but decided not to buy anything right then and there.
I quick-restored to before I downloaded 7.5, and this time my computer said it could not detect my sound device AT ALL. After some quick research I tried the quicktime reinstall and it fixed everything -- but, I was back to old 7.4.3, not able to access the store.
So, I waited and waited and waited, over two months, hoping to finally be able to access the store again and listen to songs from my computer at the same time. I was overjoyed to find out that they had finally come out with iTunes 7.6. It was a miracle! I set a quick restore point in case it corruped my audio card again, and, hoping they had resolved the problem, downloaded and installed 7.6. I restarted my computer...and...dun dun dun....
The "Found New Hardware" thign popped up again. I was instantly suspicious. I clicked "next" and once I saw the "NVIDIA" word I knew that it must not be a coincidence. Once I opened my iTunes and saw the "Detected a problem with your audio configuration" error smoke was pouring from my ears.
I told myself, self, calm down, just download your songs now, revert back to iTunes 7.4.3 by quick-restoring, and listen to them happily....even thoguh I was so not up for doing that.
So, I went to the iTunes store, it was working! I redeemed yet another iTunes card, which I got for Christmas (which need I say was about a month ago), I type in the name of a song I want to download...click "buy song"...then this new user agreement thing popped up. A little interruption in my moment of shining joy (just imagine a little halo over my head with a harp playing in the background, then the record player making a sudden stop...). I click 'OK" and then clicked "buy song" again...
"Windows could not complete your iTunes store request. An unknown error occurred (5002). Please try again later."
I shot straight up through the roof. Ears steaming, face red, temper hot as lava. Words cannot express my sheer and utter disappointment.
Can someone. Please. Help me. I have officially lost all of my patience with Apple. Two months I have been waiting and still no fix for the sound card problem. And now, another error to be overjoyed by. I don't know what to say.
I'll be back after I quick restore and re install iTunes. In the mean time, please help.

Suggestion:
When i downloaded 7.6 it completely froze my computer. I had to go to add/remove programs and complete uninstall itunes, quicktime, the bujoir service, apple update, and portable device manager- and then rebooted.
I then reinstalled 7.6; however, then it would not play any audio with video). I uninstalled quicktime version 7.4 and reinstalled version 7.31 and then my audio worked with my videos.
I am unsure if the version of quicktime is related to your audio problem; but the above is something you could try as many users using version 7.6 cannot use the newer version of quicktime with version 7.6. the newer version of quicktime (7.4) does mess up audio (at least with videos- unsure about audio tracks) --- maybe its cause; maybe not; but something to think about.
I must say itunes 7.6 as well as even previous versions are very buggy (but 7.6 is worst i have seen so far). I share your frustration.

HT201303 My iPod was stolen the police suggest we get a hold of apple and maybe they could find it but how do I do this I am not that great with these electronics

My iPod was stolen and the police suggested I get a hold of apple to maybe track it.. Were do I go to find that?

lost/stolen
No app on the iPod is required.
- If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected, on a computer browser go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone. If the iPod has been restored it will never show up.
- You can also wipe/erase the iPod and have the iPod play a sound via iCloud.
- If not shown, then you will have to use the old fashioned way, like if you lost a wallet or purse.
- Change the passwords for all accounts used on the iPod and report to police
- There is no way to prevent someone from restoring the iPod (it erases it) using it unless you had iOS 7 on the device. With iOS 7, one has to enter the Apple ID and password to restore the device.

O helpful souls of .mac-BBSland:
I have a just-past-AppleCare PB that has been perfectly reliable for 3 years. It's running up-to-latest-rev Panther 10.3.9 with several apps -- Eudora, FireFox, iTunes, iPodderX, notepad were running when the problem appeared. HD was only ~85% full.
Tonite Eudora claimed some strange errormsg, NotePad was unable to write to disk. Force Quit behaved erratically, so I thought the only thing for it was to force power-down. Twice after that time, the PB was able to power-up (from a black screen, give the "startup-chord" sound, go to a light-gray screen, then to the darker apple superimposed on that, then the spinning spoke under that). No further. After about 20 minutes in that state I decided that Further Action was necessary (and natch, AppleCare was closed)
I reset the PRAM per http://docs.info.apple.com/article.html?artnum=2238 -- no joy. Following instructions, I held down the CTRL-APPLE-P-R keys just after pressing the PWR key, waited until I heard the startup-chord twice and then released the 4 keys. The second startup-ding was perceptibly softer.
From what I could glean from http://docs.info.apple.com/article.html?artnum=14449 , resetting the PMU might be the wrong next step, so I didn't do that. The computer did in fact start up its HD, give the chord-beep indicating that the HW is somewhat OK...
Next when I started up, there was a long period where the spoke spins. Then, after many minutes, the screen went blue and the touch-pad actually became capable of moving a default-shape cursor around the screen. (I use "Mighty Mouse" to change cursor shape in my normal setup, as I recall, but things don't get that far)...
After MANY (~15?) minutes of blue-screen-with-movable-cursor, things began to move forward... buttt verrrryyyy slowly... I saw some of the normal startup screens (including a new one, "Waiting for crash reporter"). At the moment, there's a white rectangle in the center of the screen, a progress bar that's about 95% to the right, with the legend "Waiting for Printing Services"... when the cursor was outside that rectangle, it's an arrow; when it was inside, it was a spinning multicolored beachball.
I just rechecked. The screen is now black, in character-mode. White chars on black screen, atop left:
Darwin/BSD (DrDans-Computer.local)(console)
Login:
for awhile there I saw the occasional errormsg
IOATAController device blocking bus.
After a few of these, I thought I should maybe blow out any dust around the kbd, so I detached it and did so. Those errormsgs disappeared.
Since I have no idea what login and pwd I should have used, I entered FOO to login, and BAR to password. I thought I was cooked.
But to my utter surprise, the screen reverted to the small cursor ATOP MY NORMAL BACKGROUND PATTERN -- snow drifts, as I recall its name.
Upon rechecking, I see the cursor has shifted to BUSY mode (one of the MightyMouse shapes specific to my login) and the top bar is beginning to SLLLOOOOWWWWWLLLYY reappear, claiming that it's DrDan's, (I have DrDan set as the auto-boot on this laptop) the time, the battery status... but as yet it hadn't turned into the expected white bar with that info in it.
Rechecking again: White bar, all normal contents (except for Airport signal status), BUSY cursor, nothing of desktop showing... Whatta cliffhanger!
And now I gots to turn in... busy workday tmw... so this is where I need to ask you folks...
As they say in the trade, *** do I do now?
If the system appears close to OK by morning, will it reboot smoothly and as quickly as before all this crap? Yeh, I understand I better back things up ASAP...
I hear normal HD sounds, and possibly a CPU fan (if there is one in this CPU). The CPU has been physically undisturbed; I use it on a cookie-sheet on my lap, so the only stresses it has been subjected to are small torsional ones.
I have my original bought Panther disks, DiskWarrior and such. No other actual MEDIA backup (natch, I was on the point of ordering a new 17" PB or at least an external backup HD, but that never happens in time, does it.)...
I'd appreciate any Words of wisdom or pointers to where such WoWs can be found... TIA folks.
PowerBook G4 Mac OS X (10.3.9)

Welll... here's something from the Good News / Very Bad News department:
When I got home about 1:30 PM, DW reported to my delight that after 400,000-odd comparisons, it had come up with a replacement directory structure, and did I want to inspect it? I said yes, it looked file-for-file identical with the old stuff. I asked for details of the discrepancies and I could see there was a list of about 100 files, deep in the guts of obscure stuff, and media stuff,that were detected as damaged and repaired. Yayy, I said, deliverance is at hand...
So I told DW to start replacing the old with the repaired dir. About 30 minutes thereafter, the replacement process stopped. A red stop-sign alert was displayed, with this legend: "DW encountered an unexpected error while writing the replacement dir of the disk "Macintosh HD". Rebuild this disk again, preview the disk, and back up all files from the previewed disk (2164, 2659)."
I returned to the main DW display, and saw a green-checkmarked line containing the text "Rebuilding was stopped because of an error (2164)."
I looked under "ADVANCED" and read:
DEVICE id disk0S5
SECTORS 117,208,826
sector size 512 BYTES
Filesystem type: HFS (extended, jounalled)
Model: Toshiba mk6021gas
Looked to see what the GRAPH display might be... but after about 10 min, graphing stopped; errormsg "the disk named Macintosh HD could not be graphed, an unexpected error occurred (2403, 2658)" so I hit OK.
I came back and began the disk rebuild process once more. I figure that will be another long slog that will take another day while it starts from scratch.
Can anyone shed any light on those DW errormsg codes? Are they reliably bad enough such that after the next rebuilt dir is proposed, that I shouldn't even bother attempting to replace the old with the new dir? In other words, is this HD/PB hardware hosed as far as repairable until bootability is concerned? I fear so.
Sooo... said he, hope for this HD flagging (and the entire PB, therefore) ...
The rest of this msg is just speculation. Feel free to comment or correct!
Do you think it'd be worth it to ship the PB back to Apple for a HD transfer/fix? Probably expensive,since I just dropped out of AppleCare's 3-year max...
Foo. I'm wondering whether it's worth the candle to back up 60-ish gigabytes of data to CD, or even to DVD's. Many of the files are larger, I bet, than even a single DVD... And would some one of you gurus tell me how it's supposed to be possible, given no Airport/WiFi connection between this Mac (booted via DW CD) and my LAN, to backup stuff to CD or DVD? Is it possible to eject the DW disk that I'm currently booted off of (how?) and then insert a CD or DVD and then somehow burn media? I wonder where I can find out such info, if not from you kind folks (pointers more than welcome of course!)
Perhaps it'd be better to simply suck the data outta my dead PB wholesale...
Given that I was soon gonna buy a new PB with a larger HD than 60, and hopefully an external HD for backup use... Perhaps, since DW was able to see the disk and since I got a listing of my desktop contents during the slow-boot process, my files are in there, but the thing just won't boot (and there is probably a bad sector where there must not be one, to make the system bootable?).
I've heard of "Target Mode" where another Mac (that is undamaged and able to do boot) comes up, and then (somehow using target mode) makes a connection via a FW or USB connection between it and an old, bad Mac like mine with an unbootable internal HD but with data that need saving. Would it work if I just bought a new PB and then via target mode sucked all my data files (iTunes, email etc. going back years) onto the new PB's HD? If my understanding of Target Mode is correct, it would be useless with an external HD that was not bootable on its own.
Where do I learn more about Target Mode? If I were to use Target Mode between two FW 400 PB's (or a PB with an HD?), do I need a cable with standard FW-400 male plugs on both ends?
Speaking of new PB's, has anyone heard anything good about the new Intel-based "core duo" PB? I hear it's got a brighter screen, runs real fast, but has only FireWire 400 (which is what my current PB has, so perhaps that's not an issue). How compatible is it, in other words how good is "Rosetta?" I imagine I could pay a lot less for a 17" PB G4 in aluminum, with nice fast FW. But the screen's the older technology. Any thoughts?
And what's a good source of big cheap external HD's?
Tnx for your patience with all this info.
