Problem in loading the library through Servlet

Hello,
When i wrote an application which accesses my java component that has native methods and it loads the library that has the implementation of these methods, it works perfectly fine.
But now when i am trying to access the same component through a servlet it is giving an error saying : "no library xyzDLL (xyzDLL.dll) in java.library.path" . When i have my component, servlet code and the DLL in the same directory.
The code that is there in the component is :
public class MyComponent {
     public native int create(double id, int a) ;
     static {
          System.out.println("loading the Library ...." ) ;
          System.loadLibrary("xyzDLL") ;
          System.out.println("Library Loaded successfully") ;
And when i try to access the method in the servlet like :
MyComponent com = new MyComponent() ;
com.create(12.5,4) ;
Can anyone please help me out how this can be solved. I feel like i have to keep the components and the DLL at a proper directory location. Can anybody help me out where should i keep these.
I am using IBM Websphere Standard edition.
Thanks in advance,
patro

Hi,
The DLL needs to accessible in the environment of the server. I have not used websphere, but if there is a bat file that is used to start it, then put the directory where the DLL is in your PATH. Or change the system settings to have the directory in the PATH env variable. This will enable websphere to get at the DLL.

DBD: Error while trying to load the transport provider for odbc. Failed to load the library. System error: The specified module could not be found.

Hello Everyone,
We are getting an error while trying to create an Universe via Microsoft -> MS Analysis Services 2014 -> OLEDB for OLAP Provider under Connection in UDT -"DBD: Error while trying to load the transport provider for odbc. Failed to load the library. System error: The specified module could not be found." We have installed BI 4.1 SP05 in our system. As per earlier posts in scn in BO XI 3.x this issue used to be for improper installation of Integration KIT but in our scenarion Integration KIT is within the BO 4.1 package so no seperate installation is required. Moreover I have checked whether all the driver is present under file: "C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\dataAccess\connectionServer\drivers" and seems everything is fine. But still I am getting this error. One important point is we could use IDT because in IDT still we don't have option to connect with 'Microsoft Analysis Services - 2014 (XMLA)' as we are using Microsoft Analysis Services 2014 version.
Kindly help if anyone has faced the same problem with SAP BO 4.1.
Thanks and Best Regards,

Hello Everybody,
The problem is solved now after installing "OLEDB drivers from SQL Server 2012 Feature Pack". We had OLEDB drivers that comes directly from SQL Server but that did not worked out in our case.
Thanks for your support.

Slow to load the library for streaming - any NAS option that can help?

Hi
I've been using PC and recently got a MacBook. I have a NAS (QNAP) with 250Gb of music (as my iTunes library) and only want to use streaming and not store the music on my AppleTV. The problem is that every time I start up AppleTV and my Mac it takes quite long time to load the library before I can start playing music. Is there any solution to this? Is it possible to have either LAN cable or USB cable directly between my NAS and Apple TV and access the server from my MacBook this way? I had the same problem previously when using PC with the NAS connected directly to the PC and then streaming to the AppleTV.
I'm not sure whether this problem is caused by lack of memory/performance on the AppleTV when you have a large library or whether it is a problem with the wireless connectivity. Or if it is something that I haven't set up properly.
Thanks in advance

"Is it possible to have either LAN cable or USB cable directly between my NAS and Apple TV and access the server from my MacBook this way?'
I have my files on a TC but did have them on an external drive connected usb to either a TC or Extreme. I used ethernet from either router to ATV for a much faster connection than N wireless. You'll still have to wait a little bit but its worth it.

I don't own a MAC. I can probably use one at the library. I am trying to publish my book with Apple's ibooks, etc. Since my files are in Word.doc or html; how can I format my book so as to publish it?

Is anyone having problems syncing iPhoto to iPad 2 after iOS 7.0.3 update? when I click on photos tab, I get a circular dashed loading icon that is perpetually there. It never loads the library

When I click on photos tab, I get a circular dashed loading icon that is perpetually there. It never loads the library. i dont even see the iphoto content! thx for your help!

I am certain too that it is possibly the 7.0.3 update. Have you tried restoring from backup? I am uncertain that might work but its worth a try.
If that doesn't work I suggest that you give feedback to Apple directly. The more about this problem, the quicker it will get resolved.
Here's the link: http://www.apple.com/feedback/ipodtouch.html

Why Class.forName is used to load the driver ?

Hi all,
Why Class.forName() is used to load the driver ?. Can I use any other method to load the driver safely ?.

That's still redundant. Sure, it works. Here are some equivalent forms:
    new MySqlDriver();
    DriverManager.registerDriver(new MySqlDriver());
    New LinkedList().add(new MySqlDriver());
    if (new MySqlDriver() == new MySqlDriver())
        System.out.println("department of redundancy department");
    Driver unusedVariable[] = new Driver[] { new MySqlDriver() };
    Class anotherUnusedVariable = MySqlDriver.class; // I'm not 100% sure this works
    new File(new MySqlDriver().toString());
    while (new MySqlDriver() == null)
    new Double(Math.sqrt(new MySqlDriver().toString().length()) / 42);

Issue while loading the library files(".so" or ".sl") using JNI

Hi,
We are loading the c library files using system.load during the init phase of servlet.
While loading the application for the first time everything goes smooth and application behaves as expected.
We are facing the below issue when we try restarting the application through admin console in case of WAS (web sphere) for any patch deployment in the application.
java.lang.UnsatisfiedLinkError: Native Library /users/test1/siva/jnilib.so already loaded in another classloader.
If we restart the complete WAS every thing works fine.
There is no specific System.unload function available in java to remove the loaded library in JVM.
Is there any alternate way to unload the library which is loaded in class loader to resolve this issue which can be called in the destroy phase of servlet?
Any help here is highly apreciated.
TIA,
Siva.

You mean a shared library, not C files (which would be source.)
However I am not sure that loading it in a servlet is a good idea. But that is a different issue.
Is there any alternate way to unload the library which is loaded in class loader to resolve this issue which can be called in the destroy phase of servlet?This is how it works on the Sun VM back to about 1.2. And as far as I know there is no other way for it to work on any other VM.
You have a class with native methods that relies on the shared library. The class and the shared library are loaded into a class loader. If the class loader is unloaded by the GC then the native library will be unloaded as well.
A class loader can be collected by the GC if if the classes loaded by it are no longer actively references. So ALL class instances can be collected.
If the above is true then by running System.gc() twice it will collect the classloader and thus the native library.
So in your situation it might work if your app server allows you do GC (full GC is better if that is an option). You could try unloading the app, then doing the GC option several times, then do a load. Try the GC option about 6 times and the reduce it down to see if 2 work.
If that doesn't work then there could be some programmatic solutions using the same idiom.

HT1420 After updating to 11 for itunes and ios 7 for phone - I lost over 3500 songs from my itunes. My ipod still has 4100 songs on it less the most recent ones I have purchased. Can't my ipod be used to recreate the library in itunes?

After updating itunes to 11.1 and phone to ios7, I lost more than 3500 songs from my library. My ipod has 4185 songs less the most recent I purchased.
Is there no way an ipod can be used to restore the lost music? Yes, some of it was from cds but were done a long time ago. Obviously it was acceptable for me to compile this music then, now they want to say since it all wasn't purchased, I can't have what was already mine? Plus I do not use nor want to use the cloud, but it keeps creeping up even though I don't want or use it. HELP!

I recently restored my i-pod nano but it will not automatically load the library from i-tunes. I've checked

I recently restored my i-pod nano version 1.1.3, Model MA426LL. When I open I-tunes on windows 8 the library doesn't automatically download. @witsend

When I open I-tunes on windows 8 the library doesn't automatically download.
When you say "download," you are referring to your iTunes library syncing to the iPod, correct? Not something downloading from the Interent to your computer...
If you want to use automatic syncing, you need to set it up in iTunes. First, if the iTunes sidebar (along left side of window) is hidden, from the menu bar, under View, select Show Sidebar. The iPod appears under DEVICES in the sidebar, when connected.
Select the iPod in the sidebar. The iPod's Summary screen appears to the right. Toward the top, there is a bar of buttons, starting with Summary; click on Music next toSummary. This Music screen is where you tell iTunes how to sync songs to your iPod.
Check the box for Sync Music. This setting enables automatic syncing. If your iTunes music library is small enough to fit on the iPod's storage, you can choose the option to sync Entire music library. That syncs everything that is music. Otherwise, choose the option to sync Selected playlists, artists, albums, and genres. Then, select (checkmark) what you want on the iPod from the lists below. One convenient way to set this up is to create one or more playlists in your iTunes library, and put ALL of the songs you want on the iPod on those playlists. (Or you can use existing playlists.) Back on the iPod's Music screen, select the playlists under Playlists.
When you click Apply, the songs in your selection(s) sync to the iPod. Going forward, to update songs on the iPod, update those playlists in your iTunes library (add/remove songs). The iPod does not need to be connected. The next time you connect the iPod (or click Sync if already connected), iTunes updates the iPod with the same changes automatically.

Erasing unused, (never-to-be-used) images from the Library. How, please?

Is there a way to Globally-Delete a subset of, or all of, the images in the Library? I want to erase all images that are NOT being used in a Album, Slideshow, or Book.
I take many near-duplicate shots and later select only one or two for use. The accumulated never-to-be used images are becoming overwhelming. doing it manually will take many hours and there is no way to be sure that a Library image is not used in a Album, Slideshow or Book...at least that I am aware of.
I really do not need to keep 8445+ images in the Library
Many thanks,
Fred

Make a smart album - album is not any
and delete from there in groups of 100 or so emptying the iPhoto trash for each group - command-option-delete deletes photos from the library while you are in an album -- or you can flag 100 or so and control-option-delete deletes flagged photos

Use Home sharing, the library is exported, but

Using the Home sharing between my new computer and the old one, I was able to export the library from the old computer to the new computer. But it stays in the library on the new computer, what should I do next to move to the approriate place such as Music?

Go to the Advanced tab in iTunes' Preferences. Is the location specified for the iTunes Media folder the same as the location where you exported the library? Change the the location in iTunes Preferences accordingly.
