jni问题结构体参数传递

接口函数是：
char* RealRaptorDecoder(repair_symbol* RcvSymbols,unsigned short RcvNumber,unsigned short K,unsigned int T,unsigned short N)
其中的结构体类型为：
typedef struct symbol
{
  unsigned short ESI; 符号id
  unsigned char* DATA; 符号值
}repair_symbol;
在java里面对应的类是：
public class Symbol
{
public short ESI;
public String DATA;
}
在cpp文件中写的是：
JNIEXPORT jstring JNICALL Java_test_test_Jni_RealRaptorDecoder
  (JNIEnv *env, jobject thiz, jobjectArray RcvSymbols, jshort RcvNumber, jshort K, jint T, jshort N)
{
raptor r1;
jclass objectClass = env->GetObjectClass(RcvSymbols);
jfieldID ESI = env->GetFieldID(objectClass,"ESI","I");
jshort jESI = (jshort)env->GetObjectField(RcvSymbols,ESI);
jfieldID DATA = env->GetFieldID(objectClass,"DATA","Ljava/lang/String")
jstring jDATA = (jstring)env->GetObjectField(RcvSymbols,DATA);

return stoJstring(env,r1.RealRaptorDecoder(objectClass,RcvNumber,K,T,N));
}

jstring stoJstring(JNIEnv* env, const char* pat)
{
jclass strClass = env->FindClass("Ljava/lang/String;");
jmethodID ctorID = env->GetMethodID(strClass, "<init>", "([BLjava/lang/String;)V");
jbyteArray bytes = env->NewByteArray(strlen(pat));
env->SetByteArrayRegion(bytes, 0, strlen(pat), (jbyte*)pat);
jstring encoding = env->NewStringUTF("utf-8");
return (jstring)env->NewObject(strClass, ctorID, bytes, encoding);
}
报的错是：
05-10 14:18:41.810: E/AndroidRuntime(6680): java.lang.ExceptionInInitializerError
05-10 14:18:41.810: E/AndroidRuntime(6680): Caused by: java.lang.UnsatisfiedLinkError: Cannot load library: reloc_library[1311]: 1584 cannot locate '_ZN9bitMatrix9bm_rowXorEttttP13BitMatrix_Tag'...
还有一些跟这个类似的错误。
求助～～谢谢！！～～
不知我哪里写的有问题呢？？～～～ --------------------编程问答-------------------- --------------------编程问答-------------------- 你发错地方了...这里不是c... --------------------编程问答-------------------- 这是加载链接库的问题吧，应该不是这一段程序引起的 --------------------编程问答-------------------- 把"Cannot load library"的出错信息再发详细一点，这里是加载动态链接库出错 --------------------编程问答-------------------- 加载的文件位置对吗？
--------------------编程问答-------------------- 代码应该改为:
JNIEXPORT jstring JNICALL Java_test_test_Jni_RealRaptorDecoder
  (JNIEnv *env, jobject thiz, jobjectArray RcvSymbols, jshort RcvNumber, jshort K, jint T, jshort N)
{
raptor r1;
jclass objectClass = env->GetObjectClass(thiz);
jfieldID ESI = env->GetFieldID(objectClass,"ESI","I");
jshort jESI = (jshort)env->GetObjectField(RcvSymbols,ESI);
jfieldID DATA = env->GetFieldID(objectClass,"DATA","Ljava/lang/String")
jstring jDATA = (jstring)env->GetObjectField(RcvSymbols,DATA);

return stoJstring(env,r1.RealRaptorDecoder(objectClass,RcvNumber,K,T,N));
}
