JNI-Visual C++ 6.0
Hi
I want to use the file scanner�dll in java�aplication so i use JNI for that.
I read that I have to implement the wrapper JNI and for that i need to link the file scanner�file .lib but i have problem because the C++ compiler say me Cannot open file LS100.lib.
May be I don�t doy the link correctly, but I read that for link I have to follow this steps:
In project setting-----link----Object library module include the file LS100.lib but Its�t enoght
because the C++ compiler say me Cannot open file LS100.lib.
Please help me
Thank for advance and sorry for my english

Hi all,
My JNI program works fine. And also Visual Studio IDE allow to debug C++ program properly.
But after each instance of program executation(Under Visual Studio IDE) I am getting following log file.

So please tell anyone could Figure out what is this file all about??
Is this says to be worry about it .. or just provide information of current system status??
I will be obliged to you if you would help me
Thank you.This is exactly due to the memory stack.This error is entirely due to the native code.Check the native code,if there are data conversions handle them carefully
and if you are passing an array see to that the array doesnt oveflow.
Have some prints in the native code and watch the data transferred -
Creating *.dll in Visual Studio (using c++) for JNI
Hi,
I'd like to ask, if anybody has experience how to make *.dll using Visual studio (2003) and use c++.
I make *.dll library in C ( in DEV-C++), it is no problem in C , but when I use C++, it doesnt work (it is the same in Visual studio)
I have the same code like in C ( the same header , and the "same" code - in dev-c++ it works well ) but when I try to create this same project using C++ it doesn work.
Visual studio throws exeption:
c:\Documents and Settings\patak\Dokumenty\Visual Studio Projects\jniknihovna\jniknihovna.cpp(13): error C2227: left of '->GetStringUTFChars' must point to class/struct/union
type is 'JNIEnv'
did you intend to use '.' instead?
c:\Documents and Settings\patak\Dokumenty\Visual Studio Projects\jniknihovna\jniknihovna.cpp(13): error C2819: type 'JNIEnv_' does not have an overloaded member 'operator ->'
Well does anybody have any idea how to solve this problem?Well I think I use my compiler (dev-c++) corectly:
My codes :
*.h file (that is produced by javah)
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class IntArray */
#ifndef IncludedIntArray
#define IncludedIntArray
#ifdef __cplusplus
extern "C" {
#endif
* Class: IntArray
* Method: sumArray
* Signature: ([I)I
JNIEXPORT jint JNICALL Java_pole_IntArray_sumArray
(JNIEnv *, jobject, jintArray);
#ifdef __cplusplus
#endif
#endif
And *.cpp
#include <jni.h>
#include <stdio.h>
#include "dll.h"
JNIEXPORT jint JNICALL
Java_pole_IntArray_sumArray(JNIEnv *env, jobject obj, jintArray arr)
jint buf[10];
jint i, sum = 0;
(*env)->GetIntArrayRegion(env, arr, 0, 10, buf);
for (i = 0; i < 10; i++) {
sum += buf;
return sum;
and in Java : private native int sumArray(int[] arr);
and again error : 10 C:\Dev-Cpp\dllmain.cpp base operand of `->' has non-pointer type `JNIEnv_'
(when I compile it as C library, it works , but I need to use C++ in other code, I can find only examples where only *.C is used )
Maybe here is an error, but I don't know how to solve this problem

JNI FindClass Error: Using the Invocation API from visual C++
I am using JNI invocation api in microsoft visual c++ to invoke java. When I use the FindClass method, I get a return value of 0. I have verified that the class "a" exists and believe have set the java class path appropriately. A valid jvm and jenv are created. The program fails at the FindClass call and returns 0.
std::string classPath = "c:\\work\\java;C:\\j2sdk1.4.2_08;C:\\j2sdk1.4.2_08\\bin;C:\\j2sdk1.4.2_08\\lib";
vmArgs.classpath = classpath;
jint res = JNI_CreateJavaVM(&jvm, (void**)(&jenv), &vmArgs);
if (res < 0)
cout << "Error!! Cannot create jvm" << endl;
jclass jFixEngineClass1 = jenv->FindClass("a");
if (jFixEngineClass1 == 0)
cout << "Error could not find a class" << endl;
else
cout << "a class found" << endl;
thanks in advance,
hcgJschell,
Thanks for your help.
I found the error. I was using JDK1_1InitArgs for my vm_args. Since, I am using JDK 1.4, the classpath I was setting was not getting picked up. I changed the vm_args type as in the code below and it worked.
JavaVMInitArgs vmArgs;
JavaVMOption options[1];
char classPathDef[1024];classPathDef[0] = '\0';
sprintf(classPathDef, "%s", "-Djava.class.path=");
sprintf(classpath, "%s%s", classPathDef, NYSE_FIX::userClassPath.c_str());
options[0].optionString = classpath;
cout << "Option string is:" << options[0].optionString << endl;
vmArgs.version = 0x00010004;
vmArgs.options = options;
vmArgs.nOptions = 1;
vmArgs.ignoreUnrecognized = JNI_TRUE;
jint ret = JNI_GetDefaultJavaVMInitArgs(&vmArgs); -
Hi,
I am a newbie. I have a code using Visual C++ with integrated libraries. Can I interface it with Java ?
Regards,
D. Anand KumarHi,
I can explain more on the question. I would like to write a program in Java which calls a native method that's described in a C++ program.
Sample.java
public class Sample
static
System.loadLibrary("Sample");
// A native method that receives nothing and returns void
private native void test();
public static void main(String[] args)
new Sample().test(); // invoke the native method
Sample.cpp
#include "stdafx.h"
#include <iostream>
using namespace std;
void test() // native function
// function definition
I compiled and builded the Sample.cpp in a Visual C++ environment into a .dll. Now I tried to execute the java program with this dll and it said it could not find dependent libraries. I tried the following too.
#include <jni.h>
#include "stdafx.h"
#include <iostream>
using namespace std;
JNIEXPORT void JNICALL Java_RUI_test(JNIEnv *env, jobject thisObj)
//code
I added additional dependencies to the program to include the jni header from JAVA_HOME/include and JAVA_HOME/include/Win32. I builded a dll and tried to execute the java code and hit again at the same error "Unsatisfied Link Error : Cant find dependent libraries". -
Using JNI with Visual C++!! kIND OF URGENT
Hi PPL,
I am trying to interface c++ programs compiled using the g++ compiler with JNI using Visual C++, Visual C++ for some reason is not able to locate pair and map header files, so i used the header file utility.h, but the problem is changing the g++ compiled code which use pair and map.h extensively, any ideas how i can do this.I don't see anything in this that suggests it has anything to do with java.
So you might try posting to a VC++ list/board or a gnu(g++?) list/board. -
Help with JNI using C in Visual Studio
Hi,
I need help in passing arguments such as "-Djava.class.path=xxxxxxx" in Visual C++ 2005 Express Edition. I have created the .dll and an .exe which uses that DLL to call Java using c and jni. If I hard code the classpath, then it seems to work, at least partially, but I need to send to arguments through the command line. I tired it in the properties of the file but it doesn't work. Any suggestion?What is the executable you are trying to debug? A DLL that is called from java?
So your VC project is a DLL? (It's really hard to tell from your posts).
If so, then suppose you have this folder structure:
{dll_project_folder}
{dll_project_folder}\debug\mylib.dll
{java_project_folder}
{java_project_folder}\MyJavaClass.class
Then your VC project settings should be:
Command : {java_root_folder}\bin\java.exe
Command Arguments : -classpath {java_project_folder} MyJavaClass
Working Directory : {dll_project_folder}\debug

Debugging a JNI DLL created with Visual C++
Hello.
Due to the necessary libraries, I need to create a DLL in Visual C++ to be called from my Java class:
System.loadLibrary("my_dll_name");
But I've got a problem: I'm newbie in Visual C++ and I would like to debug the DLL, so when I press F5 (Go for Debug mode), I get the message "Please specify the executable file". Obviously, I've got a DLL, not an .exe or .com file.
I would be extremely obliged if anybody could share any experience.
Thank you very much.What you nee to do is this:
Run your java app (in an IDE if poss.) and have it pause at some point (if its a command line app., wait for a key, if its a Swing app, you're ok, just wait for the app. to appear. Now start VC6 and go
menus:
Build/StartDebug/Attach to process. Ther should be one process calleed java. Attach to that. If your DLL has debug info in it, you should be able to navigae to the source and set breakpoints etc.
Alternativly, you could just put OutputDebugString(...) (this is a Win32 function) statements in your DLL and use DBMON.EXE (from the win32 SDK) to look at the output. -
Version of jvm.dll compatible with 64-bit development on Visual Studio 2013?
Hi. I am building a 64-bit C++ application under Visual Studio 2013. I am using jvm.dll to call Java methods from within the application. The issue is that the version of jvm.dll that is distributed with Java 7 and Java 8 are compiled with Visual Studio 2010 (and thus rely on the msvcr100.dll runtime library). This makes it very dangerous to use with a Visual Studio 2013 application which uses msvcr120.dll (mixing runtime libraries is a very big no-no). I am seeing random memory errors as a result, at the JNI interface level.
Is there any way to get a version of jvm.dll that is compiled with Visual Studio 2013 and is thus dependent on msvcr120.dll?
Thanks,
DanHello,
As per your description, remote deployment is not possible for server side code in sharepoint so if you are using server object model then you won't be able to debug or deploy your solution from visual studio.
VS is not required to installed on UAT/prod server but you need sharepoint along with visual studio in same development machine to develop any custom webpart.
Once you deploy your custom webpart on site then you will be able to see that webpart in webpart gallery and that gallery is also available in designer so it means you can also add your custom webpart from designer to any page.
Correct me if i misunderstood you

Error in Java Runtime Environment when running JNI native library
Hi,
I am kinda new to JNI but understand it [and done some tutorials]. I am trying to implement JavaStyle [ a Java vst host that uses JNI ] and have reached a point where i successfully build the native code to a dll, and almost manage to load the native dll library. I do not get a Unsatisfied Link Error, but instead have the JVM close due an internal error.
I am completely lost and dont know what to try now, and I would appreciate any help offered.
I have debugged and the error arrives at the System.load line of code:
static {
System.out.print("Pre loadLibrary...");
System.loadLibrary("JaVaSTyle");
System.out.println("JavaStyle dll loaded in JVSTLibrary");
}Detail: I compiled the native library with MS visual studio .NET 2003 using the project settings supplied from the CVS repository.
I use Netbeans 6.0 for the java side of things. The console output is:
# An unexpected error has been detected by Java Runtime Environment:

Staring at java code will not help you figure that out.
Maybe it isn't intended to be loaded in java but instead it loads java itself?
If not then write a C/C++ basic app that links that dll in and see if you can at least get it to start. -
JNI Hotspot Error: Access Violation, need help interpreting the log.
Hello. I'm a relatively new developer (previously an engineer), and so to start me off I was given the task of providing a JNI-enabled interface to some legacy licensing software (it's C++, we want Java). Now the functionality of JNI is not the problem I have. I HAD those types of problems but now I'm having a far more obscure problem that is absolutely stumping me.
It's a Hotspot error that I cannot get rid off... and I cannot find a clear bit of info on how to interpret them.
About the problem...first off this does not happen on my development machine, where it is isolated from other components in the end-product. The integration machine with the rest of the software runs fine with a "Dummy" version of my component, but we get errors when the real version is in use. I'd really appreciate any help in understanding these things, even if it is just some general pointers.
First off here is the log

{code}
Sorry it's so long.
Anyways my dll is Jni_interface.dll. It loads legacy.dll, and its dependents. Other code also uses these libraries.
*So question 1* :
I load the jni_interface.dll (and also the legacy.dll and its dependents) library at the start of execution in a static class and so it is never unloaded. I do this because the legacy.dll will be calling functions in my Jni_Interface.dll, which are propagated into the Java class on top of it all. Does this stop other code from loading the legacy.dll or from using its functionality?
*On to question 2*:
Here is the logged output from my library, immediately before the crash:
{code:java}
*** JNI INTERFACE LIB - LOG 21 Jul 08 19:11:35.682 *** Log Level = DEBUG
21 Jul 08 19:11:35.698 - Level[ info ] - Thread[ 716 ] :: initRegistry Registry initialisation ok

21 Jul 08 19:11:36.010 - Level[ debug ] - Thread[ 716 ] :: getLicense() Get request
{code}
Now notice that the current thread in the Hotspot output is NOT the thread in my library. Thread 716 is a java thread by the way. This log appears absolutely fine according to me. Also note that in the hotspot log there is no mention of my java component (the "boss" class), which is called LegacyLM. So does that mean that is in not to do with my code even though the problem only occurs when my component is included? Or is this just the cryptic nature of these problems?
*Question 3*:
If you see the heap section of the report, there are 3 items that I have highlighted that seem like very high values. Is this a possible cause of a crash? Or would I have received an "Out of space" error instead?
In terms of actual code, I cannot post much, but I can tell you what I have done to try to solve the problem:
(i) I have added mutex synchronisation to most of my shared variables.
(ii) I have used monitorEnter and MonitorExit to control callback access to my java class.
(iii) I have re-organised my code and replaced nearly every occurance of non-string character arrays with string equivalents.
(iv) I changed how I attach and detach my threads so that I only attach/detach ones that previously were not (i.e. I leave java threads alone)
As I said at the start, I am utterly confused and I don't have much of an idea about how to proceed. I'd really really appreciate a pointer or two.
Thanks in advance.

Edited by: Diom1982 on Jul 21, 2008 12:40 PMFor those of you who might be interested, I found a solution to this problem (my version, at least). In my situation, this was caused by attempting to access the fields of a ActionEvent object in VC++ by casting a variant to a BSTR. While the cast "worked", it somehow caused the state of the Java plugin or the AxBridge DLL to get flummoxed, causing the VM dump far downstream.
The takehome message?
When seeing problems like this in the plugin / ActiveX bridge, do not assume that the causative error is occuring in the location noted in the stack trace. Visual C++, in all of its gory unprotected glory, gives full memory access to the DLL interface and you can do a serious fandango on the VM core. that won't necessarily bite you until later.
PS -- Sun gurus ... does this present a security violation in the Java paradigm? -
An unhandled win32 exception occured in java.exe , While running JNI
I'm trying to use JNI to call 3rd party VB DLL , like this
JNI <> VC++ DLL <> VB DLL
In VC++DLL ,I have function(named Open) that call 3 function in VBDLL
I have tested c++ code this function (by copy it and paste in normal vc++ project) ,and It works !
But when I call this function(Open) via JNI , I've got "An unhandled win32 exception occured in java.exe" by Visual Studio Just-in-Time Debugger !!
I think the problem is in the 3rd function that I call in Open, because when I remove the 3rd function It doesn't raise any exception.
Before I do this, I alrealdy test every function in VBDLL in VB Project , and they work fine (Include the 3rd function that I think It cause exception).
Can anybody tell me what's going on here ?
or anything that I can do to fine What cause this problem ?
Thanks in advance ^^
Edited by: voteforpedro on Sep 2, 2008 4:18 AMYou either have a pointer problem or you are calling the 3rd party library in an unexpected fashion.
In terms of testing the most likely reason is that it wasn't tested enough. Moving/changing code modifies the layout in memory which can expose previously hidden pointer problems. -
C++ do not support JNi && how to return the array from jni?
hi,
1.. I have created the Cpp file to implemement the native method but it seems that the native method can not complie rightly , it tells me follows
error C2819: type 'JNIEnv_' does not have an overloaded member 'operator ->'
c:\program files\microsoft visual studio\vc98\include\jni.h(764) : see declaration of 'JNIEnv_'
c:\users\wangyue\desktop\java_gui\beattrack 5.6 - ������_������_������������ 5.7\beattrack.cpp(202) : error C2227: left of '->GetByteArrayRegion' must point to class/struct/union
then I use the c file to paste the same code, it can complie rightly , why? I really need my native method to complie rightly in Cpp file, how to solve it?
2.I want to return a double, for the most simple way, I do the following
#include "RealBeatTrack_BeatTrack.h"
JNIEXPORT jdoubleArray JNICALL Java_playaudio_BeatTrack_BeatTrack
(JNIEnv *env, jobject j, jbyteArray data)
jdouble outdata[4]={1,2,3,4};
return (*env)->NewDoubleArray(env, outdata);
then in the java code, I difine a array to receive it,
say double mydata[] = new double[4];
mydata= BeatTrack(buffedata);
but the java comlier tells me the Exception in thread "Thread-2" java.lang.OutOfMemoryError: Java heap space?
anyone can help me?
Thanksthanks for your reply
another problem of my!
the jni pass the string, I then convert it to the
const char* filename = env->GetStringUTFChars(fname,NULL);
then I use the filename to opent the file but fails, what is the problem???
FILE *fp= fopen(filename,"w"); // there are some problem here!!!
fprintf(fp, "%s\n","wangyue fighting!");
the error is as follows
# An unexpected error has been detected by Java Runtime Environment:

After a ton of issues, I finally got this working properly. I've come across a lot of forum posts about the various problems and VERY few answers so I thought I would post my solution here.
To do this, you need to create a managed C++ layer in between C# and java. The JNI functions in C++ dll can make calls to the C# dll directly, and your java program can make calls directly to the native JNI functions. Some important notes on using C# classes in C++ are:
-gcroot<CSClass ^> should be used on any objects that are instances of some C# class.
-the symbol ^ should be used with all C# references (its the symbol for references)
-gcnew should be used to allocate C# objects
-in visual studio, add the C# dll as a reference rather than using #using <CsDLL.dll>
-do not use #using <CsDLL.dll>
The next issue is loading the libraries. By adding the folder your C++ dll is located in to the Djava.library.path VM argument, you can load your C++ library with System.LoadLibrary("Cppdll.dll"). You DO NOT need to load the C# dll in your java program. In fact, it will ignore you if you try. The problem with loading this dll is with how the CLR searches for referenced assemblies. The CLR First searches the DEVPATH environment variable (if the machine.config file has developer mode set to on), then it searches the GAC, then it searches the codebases, then it searchs the current executable's directory along with a list of definable subdirectories (probes).
DEVPATH is a decent option, but it requires modifying the machine.config file to be in developer mode. Once that is done, it acts just like the PATH environment variable.
If your C# dlls are strongly named, I would recommend adding them to the GAC or using codebases. However I have not done this and am not sure how.Hi,
i have to use a c# dll in my java program .by following this link http://www.codeproject.com/KB/cross-platform/javacsharp.aspx i done that.but it is working for only one c# program.if i am trying to use a dll it is throwing error

Please help me out. i want a few steps to invoke a c# dll by using jni -
Hello everybody, sorry to bother all of you.
I got problem with the JNI.
I'm creating a Windows service that invoking a Java-based server via JNI.
I'm copying the source from the JNI tutorial (from sun), and the problem is:
res = JNI_CreateJavaVM(&jvm, (void **)&env, &vm_args);
res will result < 0, means it failed/cannot create Java VM.
I read on JNI tutorial that said the problem is because it cannot locate the JVM, or in other words, it cannot found the java library.
I'm using JDK 1.4.1_01 now, and Microsoft Visual C++.
I'm installing the JDK under "C:\Java\J2SE"
and I'm compile the c program inside "C:\Program Files\Microsoft Visual Studio\VC98\Bin", and I'm also copied the JVM.DLL into this directory, since it's needed when i'm running the exe file.
I already set the vm_args.version into JNI_VERSION_1_4 (0x00010004)
Does anybody know the workaround about this problem?
what directory should I put into vm_args.classpath? is it ".;C:\Java\J2SE\lib" ?
Thanks anyway.
Regards,
LoekitoHere's some stuff I can tell you.
1. dont copy the JVM.dll anywhere. Use the registry to find out where it is installed and then load it dynamically.
2. look at the laucnher directory in the src.zip file in the j2sdk. there are some examples in there you should find handy.
