Could somebody help about :System.SetProperty
I use JSP to call a java class in which System.SetProperty is used to set the truststore and password for connecting to LDAP server by TLS connection .
in the java class there are following statements
System.setProperty("javax.net.ssl.trustStore",".truststore");
System.setProperty("javax.net.ssl.trustStorePassword","ldapserver");
//to set the property to access to the LDAP with TLS connection.
The java class works well when I call it by a java file .
But when I call this java class in JSP , there are some errors as following.
Who can give me some suggestions ? thanks

The java class works well when I call it by a java file .
But when I call this java class in JSP , there are some errors as following.By default, unless you are running applet or java plug-in, there is no security manager. Then all your code has all permissions. However, it is clear that your tomcat(?) instance is using a security manager.
The first thing you want to know is why or how you started your tomcat instance with a security manager. There are two directions to resolve your problem. You can start your tomcat without a security manager. Or you can add the permission for your class to change that property into the policy file for the security manager.
Lastly, of course, this problem has nothing particular to do with JSP.

Its me again with that loading problem.
Thanks for all the respond.Even after all the help I got from some of you, I couldn't figure-out what the problem is. I am still stuck with the below given issue, because of this I am unable to step further. Please help.
<u>Issue</u>:
I am trying to Load a Masterdata(flatfile) in a infoobject.
This is what i did:
I created a infoobject name 'EMPNAM' with some attributes, like [soc_sec, 0city,0country].
I created and activated communication struct , and Transfer struct.
Created my own flatfile(.csv) with some fake datas.
created infopackage and loaded the flatfile, system generated as loading successful. I checked the datas in PSA and i was able to see all the fields ['EMPNAM, soc_sec, 0city,0country] been loaded.
When i try to see the loaded data in the datatarget i.e the infoobject, i could only see the 'EMPNAM' been loaded, not the attributes[soc_sec,0city,0country].
Why is that, could anyone help me with this please.Hello Ranjani naga,
How r u ?
Just check the data in Transaction - SE11
In the Option "Table" enter "/BIC/PEMPNAM" and "Display"
Press CTRLSHIFTF10 or Contents icon
Then Execute.
Could u see the data there ?
Best Regards....

Could somebody help me improve my program
Hi i have created a program that calculates specific properties of a scanned image and uses them to create a better image cropped and angled appropriatley.
But i am having a few problems and would like to improve it. Sometimes the code will crop the image and cut out text or not angle the image properly.
Most of the time it works but i want to improve it so that it will work with any image.
Could somebody possibly look at my code and see if they can see any improvements that can be made. I would really appreciate it.
My program consists of 4 java files and 2 .bat files. I cannot use attachments on here so if u are interested in looking at the code leave a reply and i could send u the files.
Thank you
MarkHere is the PageProcess.java file. There are two versions in this piece of code one has been commented out. I haven't taken out all my comments in my code so if u do not like the comments just say and i'll take them out

Could somebody help me to get rid of mackeeper?
Advertisements everywhere. Can somebody make my day?
There is no need to download anything to solve this problem.
You may have installed the "Downlite" or "VSearch" ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
Back up all data before making any changes.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, then you may have an adware variant not covered by the support article. Ask for instructions in that case.
The problem may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
This malware is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates
if it's not already checked. -
This new "Search Web" box/bar has a magnifying glass on the left side and on the right, just outside of the box, there is "-or-". I am unable to remove it or even just move it around the toolbars, and it is unresponsive to any left or right clicks. When it first appeared, it showed up with shortcut icons for Facebook and Twitter. It would be really appreciated if someone could help me with permanently removing the above. I had already tried deleting Firefox from my Mac OS but when I re-install a new one, all plug-ins, bookmarks, etc. are retained. Alternatively could someone advise me how to do a clean uninstall of Firefox?

im using iphone 4s and windows vista. thanks.
also when i plug my phone in i no longer get asked if i want to explore files. how do i enable that? thanksHello iMuppet2,
Thanks for visiting Apple Support Communities.
It appears that your PC is not recognizing your iPhone 4s as a camera when you connect it.
You may find the troubleshooting steps in the "Windows Vista, Windows 7, and Windows 8" section of this article helpful with getting your PC to recognize the iPhone:
iOS: Unable to import photos to computer - Apple Support
Sincerely,
Jeremy -
I am running the latest OS version and uploaded the latest version of Aperture 3.1.2 all successfully installed. I have all my photos (say 12000 files) stored on a RAID WD (MyBook) external hard-drive and I assume that that has the latest software update Wd 2.25. I have previously had problems with Aperture's external referencing - which drops out frustratingly, I was in the middle of a major import of photos when the spinning rainbow ball appeared. I am now unable to open Aperture.
I have tried rebooting to no change.
Help please?Colin-
Thanks for the detailed info. One additional question, how full is each hard drive? The internal and external drives' % full.
Step one is to change the import workflow. Even though lots of manuals inappropriately lead folks in that direction, one should never import directly into Aperture or any other images management app. Instead, in this exact order:
• Restart the Mini (to clear possible memory leaks of the limiting 2-GB of RAM).
• Create a folder ("abc") for the incoming images. Since you are on a Mini you will want to be referencing Masters with the Library on the Mini's hard drive and the Masters on your external RAID array. The abc folder should be created on the RAID.
• Connect a card reader with the camera card in it. The camera card should show on the desktop. If it does not show, restart the Mini with the reader and card still plugged in. You can of course use the camera directly in this step, but I do not recommend it. Obviously cameras like the iPad do require direct camera-to-computer uploading.
• Drag the contents of the card's image folder(s) to the abc folder that you previously created on the hard drive.
• Review the abc folder contents to be sure they all copied properly.
• Software-eject the camera card.
• Physically disconnect the camera card reader from the Mini. This step is important to help avoid all-too-common human error.
• Again review the abc folder contents to be sure they are indeed all there (because stuff happens sometimes...).
• Back up the abc folder contents on to another drive.
• Review the files on the backup to be sure they all copied properly.
• At any time after but not before the previous step you can reformat the camera card in-camera. Do not delete images on the card using the computer.
• Start Aperture and only have Aperture running (due to your limited 2 GB RAM).
• Import the images from folder abc into Aperture, selecting "Store Files: In their current location" on the right-hand side of the import window.
Some generic advice I posted in another thread:
Aperture is a heavy pro graphics app that is very demanding of hardware. Your Mac's CPU, GPU, i/o and RAM are all limiting to Aperture so we need to do what we can to optimize. Some steps:
• Set Previews to only be built manually, and only tell Aperture to build Previews when you are not otherwise editing in Aperture. I suggest setting the size of Previews to be the pixel dimensions of your display.
• Keep the internal drive underfilled for speed, which sooner or later usually requires using a Referenced-Masters-Library with Masters on external drives. Back up originals before importing into Aperture or any other images app.
• The Aperture Library should be on an internal drive.
• Turn off Share Previews with iLife and iWork.
• Remember that HDs slow as they fill and keep the internal drive underfilled. Approx. 70% full _maximum_ is a good guideline.
• If page outs increase significantly during operation, max out RAM and/or try to run Aperture by itself. On my C2D MBP with its max of 3 GB RAM I always did a restart prior to a heavy Aperture session to clear any memory leaks and make sure no other apps were open. Browsers in particular will often suck RAM Aperture would otherwise be using.
IMO all Aperture users who can should routinely bump RAM to at least 8 GB.
• Some users have observed that it can take a new Aperture installation time (weeks) to stabilize on slow computers. So do not panic; and allow Aperture to continue background work by not fully shutting down the computer.

I feel like a bit of a dense idiot, I tried charging my ipod on my rents computer, came back and all my songs, playlists were gone. I don't have much of a clue with technical stuff nor if I'm posting in the right place. Any help with this would be really, really appreciated. Basically, what do I do?!?!
Thank you for your response, still a little confused, soz. I didn't do any updates on the rents comp, just plugged it into charge and left it. All my songs are still on my itunes. When I click to update it comes up with the msge songs on the ipod cannot be updated because all of the playlists selected for updating no longer exist.

Could somebody help in "how to Connect to database"
I'm trying to connect to database and there's a messege appearing tells " ORA-12154: TNS: could not resolve service name", so please if does anybody know how to solve this problem to send me a solution on my email address ( [email protected])........... Thanks
What client you are using to connect to the database??
If you are using the database's own client that the above solution works.
If you are using forms then you must set the tnsnames.ora of the forms that you are using, and not the database's.
Forms6: %ORACLE_HOME%/Net80/ADMIN/tnsnames.ora
Forms9 and above: %ORACLE_HOME%/NETWORK/ADMIN/tnsnames.ora
Or for both cases you can use the net Configuration Assistance provided by Oracle which is a GUI interface of defining TNS Names.
