Is that what this thread code safe?
I've been seeing some information that makes me think that some servlet code that I have that I thought is thread-safe is not really. I have a servlet that takes a POST request and calls a stored procedure on a database to do a few inserts.public void doPost(HttpServletRequest request, HttpServletResponse response)
{
// Check validity of request then proceed.
if (valid) { postPayment(request); }
}
synchronized private void postPayment(HttpServletRequest request)
{
/* Take some parameters from the request and call the stored procedure */
}
What I'm trying to do, is make sure 2 queries containing the same data trying to insert to the database at the same time. I did that or do I need a different approach?
Meatwad says:
Yes, I say an EJB.
This isn't something that I can help you. There is here a forum EJB (Enterprise JavaBeans which can be a more appropriate place for this question.
For the logical database are simply referring to the lock table/row?
No, I mean no transactions. Google for something like java transaction database examples for more details. While you cannot end up using such things directly if the EJB ends up handling for you (and I really don't know how they do it), it is probably that you should know the basic principles.
And can you point me in the right direction to find more information on how do this using the EJB?
Google for the EJB tutorials and examples, for EJB transactions maybe, the link to the forum above.

Satellite C650D - 10K does not start, that means this beep code?
Hello
My friend spilled tea on his cell phone, after dry at first, it worked, but now at startup it sounds right: 3 long, 2 short, 3 long and short 2.
I can't find beep codes documented anywhere, but if someone can tell me what this code is that I can at least decide whether it is worth trying to recover or clean the motherboard with isopropyl alcohol!
I tested the memory on another laptop and it's good but I can't really test the CPU, or anything else.
Thanks in advance
Hello
The beep code appears especially if the POSITION cannot be passed correctly.
If the problem is detected until the BIOS initialize the video card and the code cannot be displayed on the screen of the BIOS will play several beeps.Each BIOS supports the meanings of the own beep codes.
For example BIOS Toshiba beep code is not the same thing as "beep code" Phoenix BIOS.As far as I know the Satellite C650 supports a Phoenix BIOS.
But the BIOS is changed by laptop manufacturer so it would be possible that the beep code are different.
However, you can try to search in the internet for a description of the code.
I found this site:
http://www.bioscentral.com/beepcodes/phoenixbeep.htmBut in general these problems can be solved easily.
I recommend you contact a technician with experience huge book to analyze the material in terms of fault possible. -
Is that what this text is important in my Code?
Hey all,.
I've been busy creating my website using Dreamweaver CS5 when I noticed something in my code and did not know what it meant.
Well, then this is my query:
I my meta description tag that will say something like this within my < head > tags < name meta = "Description" content = "a free tutorial on how do this...." ' / > This is perfect so far.
However, when scrolling to the bottom of my page, almost every time I use the "ordered list" tool to add numbers in a new paragraph, copy the following code appears before: content p = 'a free tutorial on how do this... ". ">.
That's the problem, almost every time I do a new 'ordered list' code is the same that my Meta Tag Description appear in the code.
Is this a problem? This means that the search engines think that my site is spam and will not me place very?
Thank you very much
hunterguest1
It is certainly not fair, DW should not add a content attribute to a
Tag, never, let alone when you add a list.
I would defintiely remove the content = "text here" of anything other than the original meta tag.
After having cleaned out, I'd go delete the DW Cache file according to the instructions here: http://forums.adobe.com/thread/494811 and see if that isn't clear until the strange behavior.
If it isn't, perhaps an uninstall, clean and reinstall is in order. You can get the tool here: http://www.adobe.com/support/contact/cscleanertool.html
EDIT:
is the invalid code. As it is not valid, the search engines would probably ignore it, but they "could" see it as an attempt to spam/cramming.

HP 450: Is that what this laptop contains chart AMD?
Hello
I recently bought a laptop which the model has been specified as a simple "450 HP".
So my question is, my computer contains AMD graphics?
I tried to install the AMD driver available on the HP site, but it has not been successful. (only intel HD4000 is displayed in Device Manager)
its basic configuration is the following:
3230 M I5
HARD DRIVE 500 GB
4 GB OF RAM
It seems to be this one: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03315510
But the processor does not match. one installed in the present is an i5, whereas the above specifications refer without exceeding i3.
While the specs mention chart AMD, and drivers are available on the website of official drivers HP450, all my attempts to install the supplied driver (downloaded from HP) failed.
(he never mentioned material missing. it says ' warnings occurred during installation. ") (please see newspaper"but does not have the button"view log")
The intel driver installed fine.
In the device, under 'graphics adapters' Manager, is shown only the hd4000 intel.
Thanks in advance.

I found the following infromation.
http://PartSurfer.HP.com/search.aspx?SearchText=E9L71PP
If your laptop has an AMD graphics card included there should be written here.
Unfortunately, your laptop does not use an AMD graphics card.
If I'm right you have this processor:
http://Ark.Intel.com/products/72164/Intel-Core-i5-3230M-processor-3M-cache-up-to-3_20-GHz-rPGA
It is a chip Intel® HD Graphics 4000.
There is another option to determine if you have a graphics chip AMD!
You might find if available, the ID of the grahpics chip AMD hardware.
(Use as reference only)

That the "View card" menu offers you more as a non-unique hardware?

Change the screen resolution
Screen resolution refers to the clarity of the text and images on your screen. At higher resolutions, items appear sharper. They appear also smaller, so more items adapted to the screen. At lower resolutions, fewer items adapted to the screen, but they are larger and easier to see. At very low resolutions, however, images may have serrated edges.

Error code: 0x80070426. -What this means and how can it be solved?
I have Dell laptop and I'm having a difficult time with a lot of things about Microsoft. I keep trying Windows Update 10 and it won't let me. I also tried to install applications or games store, and every time I put in my Microsoft account, it says
"Something happened and your purchase could not be completed. "Error code: 0x80070426.
I got this error again when I tried to change my Microsoft account and he said
"We're sorry, but something went wrong. Your account has not been changed to this account from Microsoft. "Code: 0x80070426.
Ive tried to do a new account of Microsoft and everything but nothing works and I don't know if it's making my computer and does not allow upgrade to Windows 10. Ive restarted, it, did a factory reset, wiped out all of the computer and still no luck.
I guess my main question is: what is this error code 0x80070426 and how can I solve this problem?
After that, how can I go do the update of Windows 10 completely rather than go through the whole process just to have a window pop up after a half hour saying 'Windows 10 update could not be completed.
Hello
You could try to create media to win 10 since a different website...
Then just run Windows...
You can try to install from the site... it does not require a Microsoft Account...
If you are creating media, you have it and not need to mess with downloading more...
