Thanks for your help, but it doesnt fixed my problem.

I get ever this message
ogp_swig.h(32) : Warning 810: No jni typemap defined for int for use in OGPCallb
acks::SendTo (skipping director method)

My interface file looks like
%include "typemaps.i"
%include "arrays_java.i"

typedef unsigned char ogp_uint8_t;
typedef unsigned short ogp_uint16_t;
typedef unsigned long ogp_uint32_t;
typedef unsigned __int64 ogp_uint64_t;

typedef signed char ogp_int8_t;
typedef signed short ogp_int16_t;
typedef signed long ogp_int32_t;
typedef signed __int64 ogp_int64_t;

typedef char OGP_CHAR;

#if defined(SWIGJAVA)
%typemap(in)     (char *BYTE, int LENGTH) {
/* Functions from jni.h */
$1 = (char *) JCALL2(GetByteArrayElements, jenv, $input, 0);
$2 = (int)    JCALL1(GetArrayLength,       jenv, $input);
}
%typemap(jni)    (char *BYTE, int LENGTH) "jbyteArray"
%typemap(jtype)  (char *BYTE, int LENGTH) "byte[]"
%typemap(jstype) (char *BYTE, int LENGTH) "byte[]"
%typemap(javain) (char *BYTE, int LENGTH) "$javainput"

%typemap(argout) char *BYTE {
	JCALL3(ReleaseByteArrayElements, jenv, $input, (jbyte *) $1, 0);
}

%typemap(javain) char *BYTE "$javainput"
%typemap(freearg) char *BYTE ""

/* Specify signature of method to handle */
%apply (char *BYTE, int LENGTH)   { (char * byteArray, long len) };
#else
%apply (char *STRING, int LENGTH) { (char * byteArray, long len) };
#endif

and works good, only exception is the missing director class functions
for

class OGPCallbacks {
public:
	virtual ~OGPCallbacks() { }
	virtual void SendTo(char *BYTE, int LENGTH, const char* addrstr, int 
port) { }
	virtual void UpdateServerData(ogp_serverdata_t* pServerData) { }
	virtual int IsBanned(const char* addrstr) { return 0; }
};

or better for the sendto function only

someone knows where the problem is or how the missing typemap looks like?
