Help on using NewObject with constructors!

Question

Hi,All:
I want to create an object in a native method. The object is an instance of an inner class. The inner class has two constructors: one default and one with two arguments. There is no problem if I use NewObject with the default construtor. But if I use NewObject with the constructor taking two int arguments. The JVM crashes.
Can anybody give me some idea what the problem is?
Thanks!

Here is the native method, the inner class and error message:
JNIEXPORT jobject JNICALL Java_Prompt_createtp(JNIEnv *env, jobject obj)
     jobject test_ttt= 0;
     jclass cls2;
     jmethodID cid;     
     jint a,b;
     jfieldID fid;
     a = 10; b = 20;
     cls2 = (*env)->FindClass(env,"LPrompt$tp;");          
     cid = (*env)->GetMethodID(env,cls2,"<init>","(LPrompt;II)V");     
test_ttt = (*env)->NewObject(env,cls2,cid,a,b);
// However, the following codes using default constructor works well
//cid = (*env)->GetMethodID(env,cls2,"<init>","(LPrompt;)V");     
//test_ttt = (*env)->NewObject(env,cls2,cid);
(*env)->DeleteLocalRef(env,cls2);
     return test_ttt;
// here is the inner class     
class tp{
int a;
int b;
tp(){
a = 100;
b = 0;
tp(int x,int y){
a = x; b = y;

You are getting the constructor id on a signature that looks like:
Prompt(Prompt p, int n1, int n2)I guess that your constructor signature is:
Prompt(int n1, int n2)So it should ne:
cid = (*env)->GetMethodID(env,cls2,"<init>","(II)V");Next time please paste your code between code tags exactly like this:
&#91;code&#93;
your code
&#91;/code&#93;
