Problem with calling constructor from JNI code

843829Sep 8 2010 — edited Sep 8 2010
I have no error when I am trying to call any method of the "Ursa_Routing_Output" object from the JNI code. But I am getting the same error when calling the constructor.

Problem with the Empty constructor
Exception in thread "Thread-23" java.lang.NoSuchMethodError: <init>
at com.comail.jni.UVSdk.getRPO(Native Method)

jclass jRpo=env->FindClass("com/comail/pojo/Ursa_Routing_Output");
  	 printf("Class can't be found \n");
  	 return NULL;

	jmethodID test=env->GetMethodID(jRpo,"getAreaCommitment","()Ljava/lang/String;");
  	printf("\nProblem with the Test Method \n");
	return NULL;
    jmethodID uroEmptyConst  = env->GetMethodID(jRpo,"<init>","()v");
  	printf("\nProblem with the Empty constructor \n");
	return NULL;
The corresponding methods in the Java class are :
public class Ursa_Routing_Output implements Serializable {

	 *   Class fields 

       public Ursa_Routing_Output() {
		// TODO Auto-generated constructor stub


     public String getAreaCommitment() {
		return AreaCommitment;
The corresponding class signatures generated through javap are :

public com.comail.pojo.Ursa_Routing_Output();
Signature: ()V

public java.lang.String getAreaCommitment();
Signature: ()Ljava/lang/String;

The code is able to find the class and its other methods. But it is not able to locate the constructor.

Can any one help me to locate the problem?
