what is the reason for this one....?
In my case, whenever the user has clicked the Identify button then the native method Identify should be called. That time it's working fine.
But once the user has clicked the Enroll button, then first the Identify native method should be called, based upon the result, the enroll() native method will be called. I am getting the error whenever i am clicking the Enroll button.
while clicking the Identify button i didn't get any such error....
What would be the reason?
someone pls clear my doubt.

You have a bug in your C code, and are attempting to access memory location 0.
Look for an unitialized pointer.

Unable to call a native method

Hi All,
I am trying to call a native method tapi3Init from tapi3.dll present in Windows\System32 folder. But I get an error as below.
Exception in thread "Main Thread" java.lang.UnsatisfiedLinkError: DLLCall.tapi3Init
at DLLCall.main(DLLCall.java:25)
I have verified my java.library.path and it has the path in it. I have cross verified by typing a wrong dll name and that gave a relevant error. So, please let me know what is going wrong?
Also, is it not possible to call a native method from a dll which is not formed by using the javah header file?
Thanks.

native method tapi3Init from tapi3.dllSo that would be your JNI method.
Exception in thread "Main Thread" java.lang.UnsatisfiedLinkError: DLLCall.tapi3Init And you are not calling it. Standard reasons apply.
- library not loaded
- Signatures are different.

Why I can't call my native method from my package?

it is fine if my java code didn't complied into a package.
But if I complied my java code as a package, and call its native method outside. It give me "UnsatisfiedLinkError". And can not find my method. It is indeed the method is inside.
Thank a lot any helps. Email me on [email protected]

I have found that javah does not generate the correct JNI function names when the native function is in a class that is within a Java package. The net result is an Unsatisfied link error.
The JNI function name must be included in the package name. The naming is a bit complicated and that's why javah should be used, except in this case it does not work. I can't quite remember exactly how it works, something like adding in packagename_1 into the JNI name. The SWIG tool (http://www.swig.org) does generate the correct names when using packages. It is a tool which takes C or C++ header files and generates the JNI and Java classes for you so that you can call C/C++ code from Java. Once you have installed SWIG and run 'make check', have a look in the directory Examples/test-suite/java for the JNI naming for packages. I'll try remember to post the exact naming if you don't want to install SWIG.

Java.rmi.RemoteException: EJB Exception: while calling an EJB method,

Hi
I am getting below error while calling a stateless EJB method. There is some validation checks while performing ejb's modify() method and a RuntimeException is thrown in case of validation failure.The modify() method internally calls other stateless ejb as well.
The problem I'm facing is, instead of getting the expected RuntimeException in the Servlet, i am getting RemoteException. I am using WLS 9 MP1, all participating ejbs are stateless and i am using default transaction attributes(Supports) for these ejbs.
The interesting part is, at the ejb layer RuntimeException is thrown as expected, but this exception changed to RemoteException at the servlet's end where i am catching the ejb call exceptions.
I am new to WLS, please suggest/help me out of this exception.
Any help is truly appreciated.

Have you annotated it or denoted it in deployment descriptor?

JNI Calls to Native Methods No Longer Work: Possible Versioning Issue ?

Hello, all. Just a quick question... is it possible that invoking a method in a JNI-compliant DLL from Java 6 will fail if the DLL's source was compiled against the JNI header files from Java 4 or 5 ? I have a DLL with methods that used to be called successfully (and now fail outright and don't even seem to be getting inside the native method), but it seems that the only thing that could have changed in the environment is the installed JRE. Even stranger, I don't get the hs_err* files anymore to indicate that the JVM crashed. Does anyone know why this might happen ? Thanks !

You could of course be doing something in the JNI code in terms of working with Java which no longer works. Just as it is at least possible that java code from one version might not work with another.
Correct error checking in the JNI code would at least correctly identify this problem however.

You seem unsure whether the JNI is being called at all, so verifying that first would be a good idea.

Calling multiple DLL from Java and calling same native method

i have two dll files named DLL_1.dll and DLL_2.dll .
Both of them contain a native method which has a signature
JNIEXPORT void JNICALL Java_Database_Notify
(JNIEnv *, jclass);
This method is common to both the DLL
Now i load both of the DLL's using,
System.loadLibrary("DLL_1");
System.loadLibrary("DLL_2");
Both of the DLL are loaded form same Java Application
But the problem is that , whenever i try to call the Notify Method , it calls the Notify method of DLL_1 only.
How do i call the Notify Methos of second DLL(i.e DLL_2).
Is there any reference that i can get to all the DLL files when i load then , so that i can use that reference to invoke the Notify method of that particular DLL.

As per the description above it is impossible in java.
And I didn't say JNI, I said java.
Your above statement suggests that you think that you can have exactly the same java signature do two different things.
Note again that I said java not JNI.
A JNI method is just a tag that represents a java signature. Your description suggests that you are attempting to do it twice.
There are three possibilities.
1. Your explanation is incomplete.
2. You are trying to do something that is impossible in java.
3. You are trying to solve a problem and your description of your solution is not sufficient to determine what that is (and of course the solution is wrong.)

UnsatisfiedLinkError while calling a JNI Method

Hi everyone,
I have been struggling with this problem for two weeks now. I have a third party SDK that provides JNI library and all i need to do is implement the SDK, load the JNI library they have provided, and call the JNI methods. I was successfully able to load the JNI library and call the JNI methods when i don't put the classes in the package. But when i put the classes in a package then the library gets loaded successfully but an unsatisfiedLinkError occurs when calling the JNI methods. Please help!!! Please remember that the JNI library is provided by the third party vendor and I don't need to write the C/C++ code or call javah to create a .h file and then a c/c++ file.
This is the error i get:
Exception in thread "main" java.lang.UnsatisfiedLinkError: ss.tts.JNILayer.InitDFTTSEngineEx3(ILjava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;[I[I)V

     at ss.tts.SSMain.main(SSMain.java:13)
The three classes are SSMain, Speech, and JNILayer. JNILayer has the jni methods, speech calls the jni method, and SSMain is main class.
Thank you in advance.

which ever class which contains the "InitDFTTSEngineEx3" method. should not be altered, even its package should not be altered.[same for other class which has the native method declared in them]
because in native code jni method signatures will be based on the java class's fully qualified name.
so when you change the package the FQN will change and no matching method for this
ss.tts.JNILayer.InitDFTTSEngineEx3(ILjava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;[I[I)V
will be found in native code.
i hope u understood.

I debug my program and found that from ejbCreate()exception is getting.
I was getting the datasource object thro ejb create() initialisation.
Somehow the look up jndi which i mentioned was not interpretting from ejb-jar.xml ias-ejb-jar.xml and datasource ref .Due to this iam getting jndi Namenotfound exception which in turns to null pointer as datasource is getting null.
when i hardcoded in the ejb the the jndi name for datasource it is working fine.Bit worried all the existing ejbs working with the xml referenced datasource and jndi,but when i added a new ejb with same properties it is failing to get the jndi name.
Piece of code from ias-ejb-jar.xml

Berkeley DB JE is getting hanged while calling environment sync method.

Hi,
I am developing an application in Java and I am using JE edition of Berkeley. I am facing an issue, during shutdown operation I am calling syn method of EntityStore class and Environment class.
The EntityStore.sync() is getting completed but during executing of Environment.sync() the control is not coming out of this statement. Below is the code that I am using to perform sync operation.
if (myEnv != null) {
try {
entityStore.sync(); //Calling sync method of Entity Store Class.
log.error("Finished Syncing of Entity Store");
myEnv.sync(); // Calling Sync method of Environment Class. Control is not coming out of this sync call.
log.error("Finished Syncing of Environment");
} catch (DatabaseException dbe) {
log.error("DataBase exception duing close operation ",dbe);
} catch (IllegalStateException ie) {
logger.fatal("Cursor not closed: ", ie);
During my unit testing I was changing system date and perfoming some db operation. While I during down the application the the above code gets executed but the system is getting hanged and control is not coming out of Environment sync method call. Can some one tell why the sync is causing the system to hang.
Thanks in advance.

You did not mention the version of BDB JE. In any case for BDB JE questions the correct forum is at:

Order of arguments while calling a Java method from C

Hi
are there any rules to order the transferred arguments ?
I wanted to transfer a native window event from C to Java and if the called
java method is declared like this: (int, long, int) (IJI)V
public static void nativeMouseButtonDownCallback(int wParam, long lParam, int which)
the value of 'which' is not correct (always the same independent from what I set it to in the C function)
If I declare the java method like this: (int, int, long) (IIJ)V
public static void nativeMouseButtonDownCallback(int which, int wParam, long lParam)
everything is fine.
Any information appreciated !
Bye Mark

Thanks for your reply !
Initially I also thought that the set of the value could be wrong and so
I used a printf statement in C to monitor the transferred value.
And still: the value I put in was different from what I got in java.
After this I put in simple numbers like 1,2,3 and in java I still got
the same wrong value.(guess max signed int 21474836..)
I really replaced the dll and class files and restarted the IDE.
The problem got solved by changing the order of the long an int.

Exception while calling native profiler (root cause: no message available [

Hi,
We are setting up MAM30 using the new technology (NWMADMIN). During sync. I get the error message "Exception while calling native profiler (root cause: no message available [java.lang.reflect.Invocat...". Can anyone help me on this?
Thanks
Kind regards
Jacob

Hi Jacob,
I once faced this problem(no in MAM though)
I will try to guess the solution to your problem,
1) My first guess would be that, the header file in MAM30 using the 'javah' tool, did not pass the fully qualified name of the class as the argument. The 'javah' tool will not complain and will produce an incorrect header file.
2) The Native method names wouldnt have got a match for the java method names, might be missing the package name. here you need to import the missing ones.
3) Or you would be calling static native methods using objects, it should be accessed in a static way. you can call them directly.
Hope this helps.
Regards
Divya.

A way to set a flag in java layer when native method has been called?

Hi,
I'm calling a native method from the java layer through to a native c function. Is there a way I can set a flag in the java layer when this native method has been called?
Thanks!

1. Create a wrapper method. The wrapper method is the only exposed method. It calls the native method. It sets the flag.
2. Set the flag in the native method itself.
3. You might be able to use the debugging API to do this however it is going to require quite a bit of work. And it injects itself at runtime.
Is there a reason for this request? There might be other solutions if a general problem was posed.

Calling native methods in a package

Hi!
We have a problem when calling native methods in a class which is in a package. As you can see from the code below we have a class making an instance of a class<testBando> which makes a instance of another class<Bando> which contains the native methods. When running the program we get the error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: initialize
at test2.Bando.initialize(Native Method)
at test.testBando.<init>(testBando.java:10)
at Main.main(Main.java:5)
When we take the class that calls the native methods out of any package every thing works fine! Can you not call native methods inside a package or what are we doing wrong?
// testBando.java
package test;
import test2.*;
public class testBando {
Bando b;
public testBando() {
     b = new Bando();
     b.initialize();
// Bando.java
package test2;
public class Bando {
public native void initialize();
static {
     System.loadLibrary("bando");
// Main.java
import test.*;
public class Main {
public static void main(String[] args) {
     new testBando();

I suspect that your problem is that you have not
regenerated the signature when you placed the native
method's object in a package. Or same result but different sourc:
-package name was changed and it wasn't regen'd
-javah was run incorrectly (which gens the signatures with no package name.)

Stuck Inside Native Method

I have developed some Java code to call a third party DLL using JNI. Most of the time everything works as expected, but once in a while (generally after several days of processing) my program hangs. The root cause appears to be related to an intermittent issue with the driver that I am calling, something that I have no control over. When I perform a thread dump I can see that the thread is "stuck" inside the native method that I am calling. I am able to detect the hangup using a timer, and even obtain the "stuck" thread, but I cannot kick it back into life...or kill it in any way. Does anyone have any ideas?
My code that is calling the native method is as follows:
public void process() {
    System.out.println("Hello world from Java");
    Timer timer = new Timer();
    timer.schedule(new MyTimerTask(), 1000);
    myNativeMethod();
    System.out.println("Goodbye world from Java");
}And the code for my timer task is as follows:
public class MyTimerTask extends TimerTask {
    @Override
    public void run() {
        System.out.println("Timeout");
        ThreadGroup tg = Thread.currentThread().getThreadGroup();
        Thread[] list = new Thread[tg.activeCount()];
        tg.enumerate(list);
        for (Thread t : list) {
            System.out.println(t);
            System.out.println("---------------------------------------");
            StackTraceElement[] st = t.getStackTrace();
            for (StackTraceElement ste : st) {
                System.out.println(ste);
                if (ste.getMethodName().equals("myNativeMethod") && ste.isNativeMethod()) {
                    System.out.println("stuck thread " + t.getName() + " detected!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
                    t.interrupt();
                    break;
}

Absolutely.
I am assuming that you mean b), which is not really an option A process is a process. Doesn't matter what it runs.
An advantage that hasn't been mentioned in terms of a separate process is that if the dll has a system exception it will cause the process to exit. And there is no way to stop that. If that process is your JBoss server then it will exit. Which probably isn't what you want.
As a separate process if if exits all you need to is detect that (via correct usage of Process) and then just start it up again.
