Problem with JNI
i have to implement a few standard APIs. As a part of the implementation I have to provide references to an object I create. Now my underlying code is C++ with JNI used to throw the Java APIs. Problem is JNI now returns different references for the same object and hence my prupose id defeated. Could anyone suggest how this problem can be overcome.
I tried to figure out what your problem is, but can't. Please rephrase it and give a bit more detail on what you are doing and what is going wrong.

Awkward problems with JNI on J2SE 5.0
I'm experiencing a strange problem with JNI and I hope someone can help me out.I've installed Cygwin, MinGW and then the CDT plug-in for Eclipse C/C++ development. This means I've used the MinGW make utility. It successfully creates the DLL file, but for some awkward reason, function www_tutorial_jni_HelloWorld_displayHelloWorld cannot be found (UnsatisfiedLinkError: displayHelloWorld).
The Java class looks like this:
package www.tutorial.jni;
public class HelloWorld {
public native void displayHelloWorld();
static {
System.loadLibrary("hello");
public static final void main(String[] args) {
try {
HelloWorld hw = new HelloWorld();
hw.displayHelloWorld();
} catch (Exception e) {
System.out.println(e.toString());
}The header that was generated by javah.exe (version 1.5.0_01) looks like this:
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class www_tutorial_jni_HelloWorld */
#ifndef _Included_www_tutorial_jni_HelloWorld
#define _Included_www_tutorial_jni_HelloWorld
#ifdef __cplusplus
extern "C" {
#endif
* Class: www_tutorial_jni_HelloWorld
* Method: displayHelloWorld
* Signature: ()V
JNIEXPORT void JNICALL
Java_www_tutorial_jni_HelloWorld_displayHelloWorld
(JNIEnv *, jobject);
#ifdef __cplusplus
#endif
#endifThe C++ implementation looks like this:
#include <jni.h>
#include "www_tutorial_jni_HelloWorld.h"
#include <stdio.h>
JNIEXPORT void JNICALL
Java_www_tutorial_jni_HelloWorld_displayHelloWorld(JNIEnv
*env, jobject obj)
printf("Hello world!\n");
return;
}I've made sure that the fully qualified name of the implementation function is identical to the one in the header. I don't understand why I still get the error; especially since checking the DLL reveals that a function called "Java_www_tutorial_jni_HelloWorld_displayHelloWorld" exists.
Could someone try and produce a successfull DLL/SO from the C++ code and then try and run the Java part on a 5.0 version of Java? I'm really curious as to what on Earth is going on...... Otherwise, I would have
to add whatever directory I put my DLL into to the
PATH variable.Not necessarily. I believe the "PATH" also implicitly includes the "current directory". I also think that most JNI users put their DLL in a directory from which they also launch java (so it's in the current directory).
>
... a java.library.path set.
If I don't explicitly set a Java library path,
Eclipse can't even find the DLL. I'm beginning to
believe that Eclipse somehow screws up running Java
programs with native code...I don't know about that... Probably just something extra you have to do with your Eclipse project so that it can find the DLL.
But like I said, I don't really know - just trying to throw out ideas, small as they may be. -
Problem with JNI and Parallel Port dll
Hi. I'm doing some testes with JNI. Firs i followed the netbeans tutorial for doing a C programa that prints somthing for java.. like.. "Hello java from C".
So i tried to load a dll from my dll. Like, I have this dll to use the parallel port on windows Xp. So i created a dll to access it an comunicates eoth java.
I did everything just fine.
When I start my Java app, the first thing it does is to load this parallel port dll and configure the functions of it.
After that .. I get this error
EXCEPTION_FLT_STACK_CHECK (0xc0000092) at pc=0x0093d269, pid=2284, tid=3000
Can someone explain why ?
(Sorry if i wasn't clear enough, english is not my native language, so ask if you don't understand something.. )hi ,
I met the same problem this morning, and searched the www.google.com in order to solve it, as a result, your article was shown on my screen. :)
Till now I have read some technical information and solved my problems. Maybe the solution be useful to you:

I found some tutorial on SUN site on how to use JNI. I'm using Eclipse to compije Java and C (via Cygwin) files. Here are complete files:
Hello.java:
class Hello
public native void sayHello();
static
try
System.loadLibrary("hello");
catch(Exception e)
System.out.println("exc");
public static void main(String[] args)
Hello h = new Hello();
h.sayHello ();
}Hello.c:
#include <mingw/_mingw.h> //because there are some types needed for JNI
#include <jni.h>
#include "Hello.h"
#include <stdio.h>
JNIEXPORT void JNICALL Java_Hello_sayHello
(JNIEnv *env, jobject obj)
printf("Hello world!\n");
return;
}Makefile:
hello.dll : Hello.o Hello.def
gcc -g -shared -Wl,--kill-at -o hello.dll Hello.o hello.def
Hello.o : Hello.c Hello.h
gcc -c -g -I"$(JAVA_HOME)\include" -I"$(JAVA_HOME)\include\win32" Hello.c -o Hello.o
Hello.h : Hello.class
javah -jni Hello
clean :
rm Hello.h
rm Hello.o
rm hello.dllHello.def
EXPORTS
Java_Hello_sayHelloEverything goes well, but when I run java program it does nothin (it should print message, but it just exit without any error).I'm sure that it's something stupid, but I cant see what. Can anyone tell me what am I doing wrong?
Thenks.Answer 1: yes, there was no problem. I compiled and started simple 'hello world' program from Cygwin and from WinXP console, and it worked well.
Answer 2: This is weird, I changed code to this:
Hello.java:
public native int getInt();
System.out.println("Returned int is " + h.getInt());Hello.c:
JNIEXPORT jint JNICALL Java_Hello_getInt
(JNIEnv *env, jobject obj)
return 25;
}It does not print anything. I started this program from Cygwin and from WinXP console, and from Eclipse. Only if I debug in Eclipse (step by step) I get:
Returned int is 25and still I don't get Hello string printed (even if I go step by step). It looks like cygwin has some problem with OS. Do you have any idea what to do, I'm a bit confused?
Thank you.

Problem with JNI for target armlinux
Dear friends,
We have compiled CVM for ARM Linux and it is working fine for java programs as well as C programs.
But when I try to make shared library out of a sample hello world JNI program for arm linux it says 'jni.h: No such file or directory' and after that many lines 'syntax error' and 'parse error' etc.
But the same program is running fine on x86 linux. Problem only while cross compiling for arm linux. It is not problem with arm-v5t-le-gcc because that is working fine. Problem is with what I need to include in makefiles.
As I am new to this domain could anyone help me where I am missing?
Regards
KishoreI'm not exactly sure what you're talking about, but it sounds like you may need to look into global references. Look at NewGlobalRef() and DeleteGlobalRef() and see if those help you out.

Hi all,
I'm fairly new to programming with JNI, so please excuse me if I ask a dumb question.
I'm trying to call a Java method from a C++ class, but when I run the program, it throws an error, crashing the program. I'm pretty sure the problem is that the call to env->getMethodID() is throwing an error. I have looked around to try and find a way call a function with no arguments, but all of the examples that I have found all call a Java main.
I'll post my code and the error message below so that things are a bit clearer.
Thanks,
Robert.
Here is the main.cpp. This is where the program is started.
#include "/usr/lib/jvm/java-6-sun-1.6.0.06/include/jni.h"
int main()
JNIEnv *env;
JavaVM *jvm;
jint res;
jclass cls;
jmethodID mid;
// creation of the JVM
JavaVMInitArgs vm_args;
JavaVMOption options[1];
options[0].optionString = "-Djava.class.path= .";
vm_args.version = 0x00010002;
vm_args.options = options;
vm_args.nOptions = 1;
vm_args.ignoreUnrecognized = JNI_TRUE;
res = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);
// now the rest of the code can work
cls = env->FindClass("Test");
mid = env->GetMethodID(cls, "run", "()V");
env->CallVoidMethod(cls, mid);
jvm->DestroyJavaVM();
}Here is Test.java
public class Test
public void run()
System.out.println("stuff");
foo();
public void foo()
System.out.println("asdfasdf");
}And here is the error message.
# An unexpected error has been detected by Java Runtime Environment:

Problem with JNI and Tomcat (and threads???)
Howdy,
Here is the issue - I would like some help on HOW to debug and fix this problem:
2 test use cases -
1)
a)User goes to Login.jsp, enters user and password
b) User submits to LoginServlet
c) login calls JNI code that connects to a powerbuilder(Yes I know this is ugly) PBNI code module (this is a .dll) that authenticates the user with the database
d) the servlet then redirects to another .jsp page
e) user then submits to LogoutServlet - also a JNI call to a powerbuilder PBNI code module
f) REPEAT STEPS a-e over a few times (inconsistent) and then the call to the JNI code hangs
2)
a) users does NOT goto Login.jsp, but rather calls LoginServlet and passes the userid and password as GET parms
b) user does NOT get redirected to a page (redirect code commented out)
c) user calls LogoutServlet
d) repeat steps a-c at will and no failure, no hanging
The only difference is that in case 1 (with JSP), there is a redirect and it afffected the JNI call by haniging inside JNI code.
In case 2 (without JSP) there is still a JNI call, but it does not hang. In addition, when it hangs and I stop Tomcat, the logs show cleanup entries that say:
Oct 19, 2004 9:17:09 AM org.apache.catalina.core.StandardWrapper unload
INFO: Waiting for 1 instance(s) to be deallocated
Oct 19, 2004 9:17:10 AM org.apache.catalina.core.StandardWrapper unload
INFO: Waiting for 1 instance(s) to be deallocated
Oct 19, 2004 9:17:11 AM org.apache.catalina.core.StandardWrapper unload
INFO: Waiting for 1 instance(s) to be deallocated
Is this a threading issue in Tomcat???
On would assume that the JNI code is not cleaning up after itself, but I don't believe this is the case,
and even if it was, why would I get the tomcat log cleanup entries above???
What do those cleanup entries imply about the state of Tomcat????hi ,

Hi !
After a search on the forum, I request your help about a little JNI app developped to work with a 3D sensor. The research team in which I work use to working with Eclipse IDE, and this JNI appliation work on it. However, impossible to find a way on NetBeans... I get an exception :
Exception in thread "main" java.lang.UnsatisfiedLinkError:
materiel.videoproj.JNIsiapp.SiInitialize()I
at materiel.videoproj.JNIsiapp.SiInitialize(Native Method)
at materiel.videoproj.JNIsiapp.main(JNIsiapp.java:138)
It seems the IDE get the DLL (if I change the name in the loadLibrary method, the exception change) but encounter an error with the native method.
The application (source code + dll + java code) could be find on ftp :
ftp://ftp-us.3dconnexion.com
login: jni
password: dev1221
Please help me too find a way !
FloDeToursLibrary loading seems to continue to be a problem. There are two things to consider. First if you wrote the C/C++ code (like in the tutorials) then you compile it into a dll. This is the only dll you have to worry about. It will get loaded by your Java code using loadLibrary.
This method is going to look for the dll on the path java.library.path. If you don't set this, it is equal to the system path. I like to keep everything inside my project so I put alll dlls in a directory off my project root called "native". So I set java.library.path to "native". In any case it should point to the location of the dll if it is not on the system path.
Second if you have a 3rd party dll then you also have a JNI dll. The JNI dll is the one that loadLibrary loads, so the above applies to it. The third party dll is loaded on the C/C++ side, which know nothing about java.library.path. I only knows system path. This means that the location of this dll must be in that path. You can add the location to the system path permanently or use the IDE project setting to add it only inside the project scope.
When you deploy the app you will need to supply the various path settings in the launching code.

Problem with JNI in a Solaris shared library
Hi,
I have a problem.
I have used JNI in my .dll on Windows & .so on Solaris . I have also used the same JNI code in a .exe on Windows & an executable on Solaris. 3 out of the above 4 combinations work & 1 doesen't. When I use JNI from a .so on Solaris 8(with/without the J2SE recommended patch), the JVM seems to have some exception & dumps core when I invoke CreateJavaVM(). See Below - I've included the output on the screen & the output from 'pstack core' :

I have tried both HotSpot & Server JVMs but still see the
same behavior. I'm using 1.4 .
I'd like to provide more information to those who can help
me. I have a feeling there might be something wrong in my
CC options. Thus you will find below what my CC statement
looks like for one of the files in my project & for the
linking of the final shared library. I also have
provided the output of ldd on my shared library libaicd.so
& for comparison the output of ldd on libjvm.so as that
might provide some usefull information just incase
something looks suspecious & might ring a bell.

Hello I am using a Native code that is working perfect on Windows .
I have used DllMain calls to initialize my threads .
I attach my lower stack threads to the JNI by using these methods.
Well I want to know what is way to put the same functionality on Solaris.As this particular method is specific to Windows Platform only.
BOOL APIENTRY DllMain( HANDLE hModule, // handle to DLL module
DWORD ul_reason_for_call, // reason for calling function
LPVOID lpReserved // reserved
BOOL returnValue = FALSE;
switch (ul_reason_for_call)
case DLL_PROCESS_ATTACH:
// We do not perform any initialization
// within this section. Instead we have
// chosen to use the JNI_OnLoad function
// as the library initialization point.
returnValue = TRUE;
break;
case DLL_THREAD_ATTACH:
// We are to initialize the thread local storage
// variables in this call.
if( BridgeUtility::getInstance() -> threadInitialize() != 0 ) {
returnValue = FALSE;
printf(" Thread initialize failed..\n");
}else {
printf(" Thread initialize succed..\n");
returnValue = TRUE;
break;
case DLL_THREAD_DETACH:
// We are to uninitialize the thread local storage
// variables in this call.
if( BridgeUtility::getInstance() -> threadUninitialize() != 0 )
returnValue = FALSE;
else
returnValue = TRUE;
break;
case DLL_PROCESS_DETACH:
// We do not perform any uninitialization
// within this section. Instead we have
// chosen to use the JNI_OnUnload function
// as the library initialization point.
returnValue = TRUE;
break;If your aim is to load the library and initialize it
that one time, consider using the pthread once routines
to handle library initialization. See, for example,
chapter 5 of Butenhof's "Programming with POSIX
threads". -
Problem with JNI (custom shared library) on App Server
We have a custom built shared library (.so) we want to use with the app server (a webapp). The .so is wrapped with java class and works to spec when tested outside of app server (webapp) environment with test stub. When wrapper class is introduced to App Server (webapp) & embedded function is invoked we recieve java.lang.UnsatisfiedLinkError(). We've looked to make sure $LD_LIBRARY_PATH is correct but still recieve this exception. Any suggestions? Running nm against the .so shows undefined symbols but these should be resolved by $LD_LIBRARY_PATH. Any suggestions?
what version of appserver are u using...if 7.0 then try using their common class loader as per this docs:
http://docs.sun.com/source/817-2171-10/dgdeploy.html#wp69906 -
Problems with the ActiveX bridge for Java beans when using third-party .jar
I encountered the following problem when using the ActiveX bridge for a java bean:
I am using JDK 1.4.2_09 and MS Visual Basic 6.0 (SP6). I wrote a java bean called ProcessViewer (my class ProcessViewer inherits from JComponent and implements the interfaces Serializable and AdjustmentListener) which I would like to use within a VB 6.0 application. I used the ActiveX bridge (packager.exe) to generate a DLL (ProcessViewer.dll) and registered it successfully. The java bean GUI-control works fine within my VB 6.0 application unless my java bean (ProcessViewer.jar) uses any third-party .jar files.
But when I tried to add a reference to some third-party class (com.sap.xxx.xxx....) I got some problems. I could solve the problem with packager.exe by setting the correct CLASSPATH. But at runtime my VB 6.0 application does not work. It crashes or it reports an error like this: "The control ... could not be loaded from axbridge.dll" (although I deployed my .jar file correctly to the directory C:\Programme\Java\j2re1.4.2_09\axbridge\bin and lib). Setting the CLASSPATH environment variable before calling my VB 6.0 application (exe) did not solve the problem.
How can I teach my VB 6.0 application (containing the Java bean ActiveX control) where to find the third-party .jar file? Copying the third-party .jar file to the JRE lib-folder or to the axbridge\lib folder did not solve the problem either.
I studied the documentation about the ActiveX bridge given at:
http://java.sun.com/j2se/1.4.2/docs/guide/beans/axbridge/developerguide/index.html
but I am missing informations on how the third-party .jar files can be found during runtime of the ActiveX container (e. g. a VB 6.0 application).See how to solve your problem with JNI:

Is it a problem with jre or a problem with socket connection?
Please help me! Thanks!rohitmadiwal, don't post on old threads. If you have a problem, post a new thread.
The above error was caused by a bug in the JNI code inside of JMF. The best solution to such problems is to reboot your system, and if that doesn't work, reinstall JMF.
If neither of those 2 things fix it, it cannot be fixed.
