trouble passing float array from C to java method
I have a float array, and I am trying to pass it to a java method, but it craps out during the call to pass the array. Anyone have any ideas?
Here is the header for the java method:
publicvoid addPoints(finalfloat[] scopePoints)
and here is the C++ reference to this method:
addPoints = jenv->GetMethodID(myClass,"addPoints","([F)V");
lastly, here is the code in question (the printMsg function is just a helper function which calls a println method in my java class). Also, SampleData is defined as such: float SampleData[3072];
jfloat realGraph[3000];
printMsg("created jint array\n");
for (i=0;i<3000;i++)
{
realGraph[i] = SampleData[i];
}
printMsg("copied array\n");
jfloatArray returnArray = jenv->NewFloatArray(3000);
printMsg("created java jint array\n");
jenv->SetFloatArrayRegion(returnArray,0,3000,realGraph);
printMsg("transfered data into java array\n");
jenv->CallVoidMethod(job, addPoints, returnArray);//THIS IS WHERE IT FAILS!!!
printMsg("passed the array\n");
when i run the code, all of the print messages come through except the last one. I also added loops which printed out the contents of each array (SampleData, realGraph, & returnArray), and they all contain the correct contents.
Any help is appreciated
