JWS can't find dependent native library

Hi,
my JNLP file contains the following snippet
<resources os="Windows">
<nativelib href="lib/windows/corelib.jar"/>
</resources>
where corelib.jar contains several DLL files. The first DLL depends on others contained in the same jar file. Lauching the program under Windows via JWS, the first DLL is loaded, but it can't resolve the depencies. It seems to me, that Windows searches in the PATH, but there is no corresponding entry. (I also tried to put every DLL in a separate jar file, but that doesn't work either.)
Any suggestions who to solve this problem?

Try loading each dependent DLL from the Jar File individually, in reverse order( First load the DLL which not dependent on any other, then next level and so on). It might work this way.

Dll on Tomcat 6 got UnsatisfiedLinkError ... Can't find dependent libraries

I created a dll file and it ran with no errors on the command line. But when i deployed it together with the java class file over to Tomcat 6.0\lib and ran it with a web application, Tomcat's log file reported:

Step 4: Copied Binless.dll and Binless.class in a jar file (Binless.dll NOT in the jar file) to Tomcat 6.0\lib, and then ran a web application that called the Binless class.
Got UnsatisfiedLinkError (see above) in Tomcat's log file.
Am I missing something? Any help is greatly appreciated. Thank you.

Problem:- Hi i was trying to gererate a dll through make file using CL command using visual studio 2005 on windows 2008 (64 bit) machine. Although i was able to generate DLL file but while using this DLL file by JNI it was throwing can't find dependent libraries.
1. I used Dependency walker to check for dependent dll's(error on msvcr80.dll and etc).
2. On visual studio 2005 there are certain things: Visit link http://msdn.microsoft.com/en-us/library/ms235342(v=vs.80).aspx
Solution:- I have added mt.exe -manifest ../../generated/MyLibrary.dll.manifest - outputresource:"../../generated/MyLibrary.dll;2" just after CL command ends. it runs successfully....

Problem with "Unreferenced Symbol", phase 3, Can't find dependent libraries

now that I got every thing to work on Solaris, see my previous thread,
I'm bound to move on to Windows.
I can compile and link my C++ code but when it comes to execution I get an {color:#ff0000}<strong>UnsatisfiedLinkError</strong>{color}, complaining that it {color:#ff0000}<strong>Can't find dependent libraries</strong>{color}.
I am printing out the java.library.path property before loading my lib and it has the necessary path to all my libs in it.
Here my 2 questions:
1.what do I need to do to get this to work on Windows?
2.is it mandatory that dependent libraries are also .dll's on Windows (the library my native code needs is a .lib)?

unfortunately, the exception does not say, what is missing:

Java.lang.UnsatisfiedLinkError.Can't find dependent libraries

Hello,
I call in an applet a library "ezmodJava.dll" in order to execute a native method. It works very well in my computer (Windows 98). I've put "ezmodJava.dll" and a dependent library "ezmod.dll" in directory C:\Windows. That works very well.
Now , i try to run the applet in a station(Windows XP) (in a network). I've installed the libraries "ezmodJava.dll" and "ezmod.dll" in C:\windows, but it doesn't work. I've put them in C:\windows\system and in C:\windows\system32 but no way. The last error i had IS :

Any help will be appreciated. Thank you too much.

on your computer you might have multiple copies of the dll. try temporarily renaming the dll...then run the program. if it runs, you know you have another copy somewhere. do a search and find the extra copy...rename it and run your program. your program should fail then and you will find which directory your program is looking in for the dll.

Please help...Can't find dependent libraries.

I've searched and read, and tried several things but every time I run my application I get this:
java.lang.UnsatisfiedLinkError: C:\JBuilderX\Projects\AlwaysOnTop\AlwaysOnTop.dll: Can't find dependent libraries
     at java.lang.ClassLoader$NativeLibrary.load(Native Method)
     at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1560)
     at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1485)

     at alwaysontop.AlwaysOnTopApp.<init>(AlwaysOnTopApp.java:22)
     at alwaysontop.AlwaysOnTopApp.main(AlwaysOnTopApp.java:68)
Exception in thread "main"
Here is exactly what I did, maybe someone can spot what I did wong:
1) Created AlwaysOnTop like this:
package alwaysontop;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.awt.event.*;
public class MainFrame extends JFrame
static
   System.loadLibrary("AlwaysOnTop");
   //Runtime.getRuntime().loadLibrary("AlwaysOnTop"); //Tried this too...same thing
public static native void setWindowAlwaysOnTop(String title, boolean flag);
...2) I then built the application
3) I opened a command prompt and went to the classes directory just on top of alwaysontop directory. It looks like this:
C:\Projects\AlwaysOnTop\classes\alwaysontop
So, I was in the C:\Projects\AlwaysOnTop\classes level
3) Next I generated the header file like this:
javah -jni -classpath alwaysontop MainFrame
4) Copied MainFrame.h over to the CPP project area.
5) Created a C file (not a C++, tried that first, then tried C style after reading something that recomended it). This file looks like this:
#include "jni.h"
#include "MainFrame.h"
#include <stdio.h>
#include <windows.h>
#pragma argsused
int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void* lpReserved)
        return 1;
JNIEXPORT void JNICALL Java_Win32Native_setWindowAlwaysOnTop(JNIEnv *env, jclass obj, jstring strWindowTitle, jboolean bAlwaysOnTop)
        HWND hwnd = NULL;
        const char *str = (*env)->GetStringUTFChars(strWindowTitle,0);
        hwnd = ::FindWindow(NULL,str);
        (*env)->ReleaseStringUTFChars(strWindowTitle,str);
        if (bAlwaysOnTop)
          SetWindowPos((HWND) hwnd,HWND_TOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
        else
          SetWindowPos((HWND) hwnd,HWND_NOTOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
        return;
}6) Copied the DLL that got generated to thw Windows\System32 directory.
7) Ran the application from JBuilder.
8) Got the error...banged head into wall for umteenth time.
Note that the java.library.path looks like this:
C:\JBuilderX\jdk1.4\bin;.;C:\WINDOWS\System32;C:\WINDOWS;C:\WINDOWS\SYSTEM32;C:\WINDOWS;C:\WINDOWS\SYSTEM32\WBEM;C:\DMI\WIN32\BIN;C:\Program Files\Microsoft SDK\Bin\.;C:\Program Files\Microsoft SDK\Bin\WinNT\.;C:\JavaSDKs\j2sdk1.4.2_01\bin;C:\Ant\bin; ...
So the C:\Windows\System32 is there!
What do I need to do for Java to be able to find the dependant libraries?
THANKS!

Make sure your DLL exports a function named exactly
Java_alwaysontop_MainFrame_setWindowAlwaysOnTop
without any C++ name mangling or other mismatch. You
can use a tool like dumpbin for this.
-slj-
You might be on to something. I couldn't get dumpbin working (no output...tried several options) so I used another tool and it showed the following as exports:
Entry Point = 004020F8h
Ordinal = 1
Name = __CPPdebugHook
That is all! The imports look correct, so I think there really is nothing else being exported.
Here is what my AlwaysOnTop.c file looks like:
#include "jni.h"
#include "alwaysontop_MainFrame.h"
#include <stdio.h>
#include <windows.h>
#pragma argsused
int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void* lpReserved)
        return 1;
JNIEXPORT void JNICALL Java_alwaysontop_MainFrame_setWindowAlwaysOnTop(JNIEnv *env, jclass obj, jstring strWindowTitle, jboolean bAlwaysOnTop)
        HWND hwnd = NULL;
        const char *str = (*env)->GetStringUTFChars(strWindowTitle,0);
        hwnd = ::FindWindow(NULL,str);
        (*env)->ReleaseStringUTFChars(strWindowTitle,str);
        if (bAlwaysOnTop)
          SetWindowPos((HWND) hwnd,HWND_TOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
        else
          SetWindowPos((HWND) hwnd,HWND_NOTOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
        return;

UnsatisfiedLinkError: Can't find dependent libraries

Hello,
Am currently developing an application based on JNI. I have, after linking required libraries in c and compiling it, created a dll file 'hidapi.dll', which i load in java program via System.loadLibrary("hidapi") and compile it. When i run it in my machine (after of course, putting the dll file in System32 folder - Am using Wn 7 for your info.. ), the code runs perfectly fine. So far so good.
But when i put the dll file in another machine the dll file is not getting loaded... My code gives an exception java.lang.UnsatisfiedLinkError: C:\Windows\System32\hidapi.dll: Can't find dependent libraries... When i tried to have the verbose messages through -verbose:jni , I get the following message.

hidsignalapi.UsbPctoolJni is the class where i load the dll file, and line 46 is exactly the line where i wrote 'System.loadLibrary("hidapi");'
I saw in a few forums to ensure the class names are correct... But if that is the case, it must not run in my system too right? The only linked files are jni.h and a custom library hidapi.h. Should the hidapi.h too must be put in classpath? Has any body has any idea about this..?
Thanks,
Sreram

It is technically possible to create a C/C++ application without using compiler libraries but it that is an esoteric subject that has nothing to do with anything you might be doing with JNI.That is exactly, being a java programmer, where am stuck.
I am rather certain that the missing component, hidapi.dll, has nothing to do with C/C++ compiler libraries. Yes. I, in my Java code, am loading the hidapi.dll dynamically, to perform some communication with the USB device, which is a JNI C dll, I created using VS2010 and the C code uses the static library setupapi.lib (for communicating directly with the OS).
And unless you have a static library for that, which is not the same as the dll, there is no way you are going to link to that statically.I have MS SDK V7.0A pre-installed (along with Visual Studio - VS2010) in my system which has the library. So it works in my System (Windows 7). Problem arises only when i try to run the same code in another system, which has no VS.
Realistically what it really comes done to is that you must understand what dependencies your own application has first before you explore the options for delivering it.That is exactly what i am trying to do here.
Now i have a few questions here.
One: Do i need to install SDK in every system for the static linking and in tun my code to work? Or will it suffice if i put the setupapi.lib in path? Or should i convert the static linking to dynamic linking? (I realize i am asking more of C related questions in a Java forum, but I am sure your answers will help me in creating a working code.)
Two: After pathetically failing to create a working dll with VS2010, I tried to compile the code using Mingw gcc compiler and my code (C & JNI code) compiles successfully, but I do not know how to create a dll file by properly linking with the library files.
After compiling the code with the -c option, creating hid.o for the hid class and hidapi_wrap.o for the JNI wrapper, I tried to create a dll with the following command.
D:\Sreram>gcc -Wl,-kill-at -o hidapi.dll hidapi_wrap.o hid.o
hid.o: In function `hid_enumerate':
D:\Sreram/hid.c:286: undefined reference to `_imp__SetupDiGetClassDevsA@16'

C:\MinGW\msys\1.0\src\mingwrt/../mingw/main.c:73: undefined reference to `WinMain@16'
collect2: ld returned 1 exit status
Obvious that the linker has no clue about these functions which are defined in external library 'Setupapi.lib' & setupapi.dll and hence I tried linking the file by adding the command '-lsetupapi.lib' (without 's), '-llibsetupapi.a' and -l'setupapi.dll' in vain. The compiler says
c:/mingw/bin/../lib/gcc/mingw32/4.6.1/../../../../mingw32/bin/ld.exe: cannot find -llibsetupapi.a (with whatever linker option i give)
collect2: ld returned 1 exit status
What am i doing wrong here?
And three: Even if i succeed in creating a working dll, will it work in other Windows operating systems - I know i had to create a separate library file (.so) in linux and whatever in mac - like Windows XP, Windows Server 2003, etc.?
Thanks for your patient replies and excuse me for such a long reply.

Can't find dependent libraries

Hi,
I try to load a DLL, but I get an exception.
public class JNIExportToX {
// load library JNIExportToX into JVM
static {
System.loadLibrary( "JNIEXTERNAL" );
public native boolean EXTERNAL_ParametersChange(String param1);

at java.lang.System.loadLibrary(System.java:1030)
what can be the problem?
Thanks,

Hi,
Your dll is trying to load another dll that is not in the path.
You may call System.load("F:\\ull\\Path\\Of\\The\\Dependant.DLL"); to workaround this problem.

"Can't find dependent libraries" Query

I created a sample.dll using VC++ which inturn uses java libraries. I
was getting 'file.obj : error LNK2001: unresolved external symbol
__imp__JAWT_GetAWT@8' link error while creating sample.dll even after
providing jawt.dll path. So used jre/lib/jawt.lib to create the
sample.dll. I am using this sample.dll to run a java program. While
running the java program, I am getting the error 'Exception in thread
"main" ava.lang.UnsatisfiedLinkError: sample.dll: Can't find dependent
libraries'. If I don't use jawt.lib (by commenting relevant code) to
create sample.dll, my java program runs fine.
But I need to use the code relevant to jawt.lib. Any idea how to over
come Can't find dependent libraries error?

You need to link against "jawt.lib"
E.g.
In VC++ goto
Projects -> Settings ->Link Tab
Add jawt.lib to the Object/Library modules and Project Options.

Single Sign On - SAPSSOEXT - Can't find Dependant Libraries

HI
I am trying to implrement SSO to another server running in IBM Websphere 5.1
In my java code System.LoadLibrary fails for SAPSSOEXT and error message is "Can't find Dependant Libraries"
concerned java code is
public static String SSO2TICKETLIBRARY = "sapssoext";
try {
System.loadLibrary(SSO2TICKETLIBRARY);
} catch (Throwable e) {
System.out.println ("Error during initialization of SSO2TICKET:\n" + e.getMessage());
Both of sapssoext.dll and sapsecu.dll are in c:\windows\system32 folder and I have downloaded the files relevant to my OS from SAP service marketplace.
Version of sapsecu.dll 6400.243.0.0
and version of sapssoext 5.4.28.5
I have used SAPSECULIB54_3-10002911.SAR
and SAPSSOEXT_4-10002921.SAR for those files
OS where IBM websphere is run is Windows 2000
c:\windows\system32 is very much in the path and undoutably it finds sapssoext.dll. Probably it requires some other dependant dll.
How can I trace to find which library is missing
Regards
Saurav

Java.lang.UnsatisfiedLinkError: ocijdbc9.dll: Can't find dependent librarie

Hi all,
I have written a simple code to connect to Oracle9i in WindowsXP.
Oracle is installed and running on Linux machne on the Intranet.
I have set 'classes12.jar' in classpath and placed following dlls in "C:\WINDOWS\system32" path
ocijdbc9.dll
ocijdbc9_g.dll
heteroxa9.dll
heteroxa9_g.dll
Following is the part of code:
public String dbName = new String("jdbc:oracle:oci8:username/password@sid_192.168.0.128");
public String dbClassName = new String("oracle.jdbc.driver.OracleDriver");
Class.forName(dbClassName);
conection = DriverManager.getConnection(dbName);
statement = conection.createStatement();
When I run this code got following errors:

There are only a very very few and rare good reasons to use the oci8 driver with Java (and I can't remember any of them at the moment). Performance is not one of them. If at all possible, you should use the Type IV (thin) driver instead.
The classes12.jar (or zip) is for use with Java 1.2 and 1.3. There are different versions of this jar for each version of the database, but they're fundamentally cross-compatible; all the post-8i drivers are supposed to work with all the post-8i databases (and the 8i stuff also mostly works too). There's been a succession of bug fixes and minor functional changes, as well as some very substantial perfromance improvements. If you are developing brand-new code, I very stongly encourage you to use the very latest driver (currently 10.2.0.1, I think). If you are using a Java version greater than 1.3, then you should use the ojdbc14.jar instead (and don't try to use both classes12.jar and ojdbc14.jar, they have the sameclasses in them). I think the 10.2.0.1 ojdb14.jar was the first one certified for Java 1.5, and it's significantly faster than the 9i drivers. Anyone considering an upgrade of drivers should plan to do a good regression test; as mentioned before, there are some very small functional differences. You can download the latest drivers here:
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
If you insist on using oci, then you probably need to do an Oracle client installation on your Windows box. If you stay with the 9i driver, the full client install is huge; however, you can almost certainly use the 10g "Instant Client", which is a pared-down version, with just the minimal stuff to support an application. That's available here:
http://www.oracle.com/technology/tech/oci/instantclient/instantclient.html

Creating one, but that may not by what you wantand

May by I made mistake used dllwrap, what this feedback means for me?
So, when I did everything what I wrote abow I got:
HelloNative.class
HelloNative.h
HelloNative.o
HelloNative.dll
and I run
HelloNativeTest.class and I got above Error
I use j2sdk1.4.2 and Windows XP
Could anybody tell me what I did wrong???
I will be appreciate

How can I transfer my stickienotes data to a new computer? I can't find it in Library as I should

How can I transfer my stickienotes data from my imac to a new macbook air computer? I can't find it in Library as I should.

You can download CS4 here. Download CS4 products
Most comments I've seen say CS4 needs to be run in compatibility mode on Win 8.1. Windows 8.1 compatibility for Adobe Photoshop CS4 version 11
But the only way to know for sure is to try it.

Hi,
Where are you getting the error from ? what product
You should have a directory :- \Hyperion\common\ADM\9.3.1\Essbase\9.3.1\bin
which contains HssJNIDriver931.dll and others.

ITunes can't find my music library. Pleas help!

I just upgraded my iTunes. Next time I tried opening it a window appeared that read: "Can't find your iTunes Library..."
I tried searching by opening start/computer/iTunes but the file that has all my music was renamed to: bd4765ae206e5a7a782a28f08509 and when I tried opening it all I found was a list of 4 files that I can't open.
I know all my music is still there because the file still uses 125 GB in my computer, but I can't seem to run iTunes or I can't seem to point iTunes into finding my music.
Please anyone help!!!

If you did not rename that file, then I am a little worried there might be a larger problem looming (malware, etc.). If this is so, then finding the file might not even help.
I recommend restoring from a backup. If the backup was made before this file changed, then you should be fine.
If you would like to stick with what you've got, then this Apple Support article should provide you with the instructions you need: http://support.apple.com/kb/HT1391
Best!
