FATAL ERROR in native method: JNI call made with exception pending
Hi everyone,
I am trying to resolve this error exhaustively for the last 3 days.
I have a 3rd Party DLL library which i am supposed to use from my Java Application. I compiled my own DLL that links(calls methods) the Java code and the the 3rd party DLLs.
It works fine in my machine and 2 of my other colleagues but does work for the QA tester. The JVM crashes when it comes to the point of loading the DLL with the exception mentioned above.
For the QA tester, a version of the DLL made in VC7.1 works fine, but the one we are trying to load was made in VC80.
It also has the dependency dll like msvcr80.dll and msvcp80.dll
We both have Windows XP and same the JVM (1.4)
Please Help !!!!!!!
Thanks,
Zuber
I would suggest further investigation of dependencies. If the QA machine doesn't have VC 8 check what the diffs are there.

Dear all,
I am working on a MacOSX. I am having trouble in using a Dynamic Library generated from C files and accessed from a java project using JNI.
The loading of the library work well bur when i try to access a method I have the following error:
FATAL ERROR in native method: JNI received a class argument that is not a class
at cytosolve.sbmlSolver.SBMLSolver.initSolver(Native Method)
at cytosolve.sbmlSolver.SBMLSolver.<init>(SBMLSolver.java:87)
at cytosolve.sbmlSolver.cytosolve.main(cytosolve.java:29)where the Native method inside the C file is the following:
JNIEXPORT jint JNICALL
Java_cytosolve_sbmlSolver_SBMLSolver_initSolver(JNIEnv *env, jobject obj, jstring model_filename, jdouble totalTime, jint numSteps)and it is called from the Java file as:
int successCode = initSolver(model_filename, totalTime, numSteps);Do you have any idea on where is the problem and how to fix it?
Thank you,
Eva.Everything seems to be right. Maybe you use JNI functions inproperly?

FATAL ERROR in native method: Wrong Method ID
I have a piece of C code from which I am trying to launch a piece of Java, but I am having severe problems just trying to get a simple integer value returned from any Java function. I keep getting the error message "FATAL ERROR in native method: Wrong method ID used to invode a Java method"
My C code looks like :
JNIEnv *env;
long result;
jmethodID mid;
jclass cls;
jobjectArray args;
jstring jstr;
jint res;
jobject myObj;
options[0].optionString = "-Djava.class.path=.";
options[1].optionString = "-Djava.compiler=NONE";
options[2].optionString = "-verbose:jni";
vm_args.version = JNI_VERSION_1_2;
vm_args.options = options;
vm_args.nOptions = 2;
vm_args.ignoreUnrecognized = JNI_FALSE;
// Create the Java VM
result = JNI_CreateJavaVM(&jvm,(void **)&env, &vm_args);
if (result == JNI_ERR )
printf("Can't create Java VM\n");
exit(1);
else
printf("Java VM created successfully\n");
cls = (*env)->FindClass(env, "Example1");
if (cls == 0){
printf("Can't find Class\n");
exit(1);
else
printf("Class Found\n");
mid = (*env)->GetMethodID(env, cls, "GetIntValue", "()I" );
if (mid == 0) {
printf("Can't find function\n");
exit(1);
else
printf("Function Found\n");
res = (*env)->CallIntMethod(env, cls, mid);
if (res != 0)
char pszTempString[256] = {'\0'};
sprintf (pszJavaString, "Returned from Java the value of %d", res);
printf("Returned from Java with ");
printf(pszJavaString);
My GetMethodID call works correctly and I have checked the signature (using javap -s) and that works fine. I've seen many references on these forums about using NewObject prior to calling CallIntMethod, but if I try to use that I then get the error message "FATAL ERROR in native method: a non-constructor passed to NewObject".
Any body got any ideas please.
ThanksWhat I couldn't figure out from your code is where you create the java object that is supposed to return the integer to your C code.
Alternatives:
o This is just code snippets, and you really are creating the object.
o Error - the object should have been created.
o Error - it is a static method, and you should be finding a static method and calling it on a class object.
(Other than that, I didn't see anything obviously wrong. -

Forte debugger exits (FATAL ERROR in native method: JDWP "util.c")
When debugging my GUI app in Forte on Solaris 8, my debug session exits with the following error:
FATAL ERROR in native method: JDWP "util.c" (Feb 20 2002), line 1029: Unexpected error, error code = 113 (JVMDI_ERROR_INTERNAL)
It seems to do so while in the middle of a comm api routine where I'm accessing the serial port. Has anyone else ever seen this error is Solaris? I have all of the patches required by Sun for JDK1.3.1_02 installed with the same version of the JDK.
The application runs fine when I run it standalone...
Any suggestions?
Thanks.I've had the same problem. It appears that it occures when an error is thrown that stop a JSP page load.
Everything will run find up to that point, but after that, the util.c error will not go away except by deinstall and reinstall of Forte. We can't even use Forte at this point since it will start throwing the error within 1 hour of reinstall. Crap.
I'm on Windows XP also, and this happens with JVM 1.3 or 1.4. -
FATAL ERROR in native method: Non-array passed to JNI array operations
After stepping up to JDK 1.4.2 we started getting a hotspot error, I added -Xcheck:jni and it yielded the above error which was not existent in JDK 1.4.1 and for the life of me I cannot find out whats wrong:
Native method dec:
private native byte[] cost(final byte[] byte_array,
final double minCostPerMeter,
final int costFuncSelection,
final double maxCostThreshold);
Method call:
ByteArrayInputStream
inputByteStream = new ByteArrayInputStream(
cost(output_byte_stream.toByteArray(),
minCostPerMeter,
costFunctionSelection.length,
maxCostThreshold));
An array is being passed I have no idea why it is complaing about the method call.
Any help would be appreciated.
-RWhat happens if you remove all the code from the JNI method - so it just calls and then returns?
If it still occurs then I would expect that you have a memory problem in a piece of code before this one. Such problems can have no impact when run in one environment but cause failures in another becomes some other legitimate piece of data moved.
If it doesn't then I would expect that the problem is in the method itself and not the call.
It could be some odd VM problem so trying a different version of 1.4.2 might help (but in of itself would not eliminate the possibility that you have a memory problem.) -

Fatal error in function BldAlter on call to function GetOldRecDefn
Greetings anyone. Thx in advance for the help.
My issue is that I'm getting errors running the steps "Task 7A-24: Running Alter Audit" from the Ptools 8.50 installation guide.(plan to isntall FSCM 9.1 next). The error is as follows and I get it for every statement executed during the build process...;
SQL Build process began on 6/22/2010 at 12:01:40 PM for database PSOFT.
Error: EOCM_TER0000101 - Unable to retrieve current DDL space name. Alter processed failed. (76,47)
Error: Fatal error in function BldAlter on call to function GetOldRecDefn. Return code = 1. (76,6)
I'm pretty sure I've followed all the installation steps correctly. The only remedy step I found helpful from Oracle Support is to make sure my PSDBOWNER is upprcase. I did change that, to no avail. There were some VIEWs discrepencies when I ran DDDaudit(none for sysadudit. But that's because AUC_SCR_CHT_VW would always hang when replacing views. Any direction would be much appreciated.

Hello, I am trying to complie some C code for some applications I am working on in labview (I am using Labview 2012 64bit).
When I try to build my code in Visual C++ 2010 ( I have set it up to be able to use x64) I get the following fatal error:
nivision.lib(StartupShutdown.obj) : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'
Which I understand that .lib does not have a 64bit compatability. However, if I were to use 32bit code, how can I link/emulate it to my 64bit labview? Is there a good tutorial on this application? The problem is the rest of my application uses and requires 64bit labview, so I am stuck in this enviroment.
Thanks.dbrittain wrote:
Thanks for the reply. The C code I have cross correlates images, and it does reference the image inputs and size variables from the nivision classes. I am thinking of using a side by side labview environment with shared variables. I have not done this before, do you have any good examples? Can you make the library function node a shared variable or only the elements within it?
I guess I could try to convert to labview, but the are a lot of lines of code that I would prefer not to try to wrap my head around in translation.
The LabVIEW API in Vision Development Module has functions that let you get access to all those parameters as well as the raw image data pointer. A common design is to query those items on the LabVIEW diagram and then pass them to your DLL. This would mean you wouldn't need to make any calls into the Vision DLL from your C code.
As for examples showing how to use shared variables, keep in mind that it isn't just like doing a function call. The more appropriate way to think of it would be communicating with another VI by getting and setting controls and indicators while it runs. You could put all your arguments into a shared variable and set a boolean indicating it is ready, then wait for another boolean to go high indicating the other code has finished and placed its results in another shared variable. Your application code interacts with the shared variables just like a control/indicator/local variable. This of course is a simple description and I would not be surprised if there are well-defined frameworks/examples searchable in the forums that use shared variables in this manner.

ERROR_WAIT_NO_CHILDREN error while native method calling
I have some self-made DLL and call it from Java over JNI.
Under 100% repeatable conditions, the calling of the native method conduce to
java.exe(JVM) termination with errorlevel 128L. Without any trace or reports.
If to assume, that java.exe uses OS error codes, then 128L is
'ERROR_WAIT_NO_CHILDREN - There are no child processes to wait for.'
What that? JVM crashed by the Dll?
Some additional information:
I found the position(approximately) in C code where the execution is stopping.
It far from JNI/C function declaration.
Dll is compiled by Watcom C/C++32 Compiler and Linker, Version 11.0.
I tried to compile Dll by Borland C++ 5.5.1 free command-line compiler, and error
disappears. But I don't think it right way to refer the error to compiler.
And something else. Native code work fine, if it was called not from Java but
from native application.
Any ideas?
Thanks.Hmm, could You send the header of the method from Your
DLL which you are calling from Java?Sure.

Error while transforming XSLT by calling function with Reflection API
Hi,
I'm new to Reflection API. I want to call function from the jar file which is not in my application context. So I have loaded that jar ( say XXX.jar) file at runtime with URLClassLoader and call the function say [ *myTransform(Document document)* ]. Problem is that when I want to transform any XSLT file in that function it throws exception 'Could not compile stylesheet'. All required classes are in XXX.jar.

Federico NavarreteThe array that you're calling Monitor.Enter under is not always the same array that you call Monitor.Exit on. When you resize an array using Array.Resize, you pass the variable in as a reference parameter (ref). The method then creates a
new array object and assigns it to the array variable. Then, when you leave the synchronization block after resizing the array, your Monitor.Exit uses the new array rather than the one it originally entered
and... boom.
Instead of locking on the array itself, create a new private readonly field of type Object called "lock" within the SmartArray class and use that to lock on. It doesn't
need to be readonly, but the keyword will prevent you from accidentally introducing this issue again. -
Fatal error: LABVIEW.LIB was not called from a labview process
I have built a very simple executable which uses shared variables which should talk to an OPC server. When I try to run it on the target machine, I get this error. Does anyone know what it means?
If you up/down graded from 8.2 to 8.5 then I would suggest doing a mass compile on the VI's into a new folder (or have a backup of your files somewhere).
You can do this via LabVIEW > Tools > Advanced > Mass Compile.
Please let me know how this turns out.
All the best,

Hey,
I'm with Optus in Australia and they dont have "Live Billing" or what ever there excuse was. SOOO i cannot check how much i have used on my plan, untill the bill comes out. Yes i know its gay.
Here is where i want to track calls. My old phone (LG K800) had a feature where you can input call cost per 30 sec block and price per SMS and it told you how much you should have spent. Does the 6110 have a feature like this that i have missed ?? Alternatively, is there an application i can get that does this??
If not, is there a way i can transfer my log of calls and SMS's to my computer so i can put all that into a program and do the same thing??
