動(dòng)態(tài)鏈接庫(kù)的方法如下：__declspec(dllexport) ret __stdcall rLachTran(const char *pc_trancode,

const char *pc_clicode,

const char *pc_orgcode,

const char *pc_ttycode,

const int i_brandid,

const char *pc_reqstamp,

const int i_reqseqno,

const char *pc_svrip,

const unsigned short us_svrport,

const char *pc_reqmsg,

char *pc_resmsg);

我需要發(fā)送一條短信隨機(jī)碼出去，而我的JNi類(lèi)如下：package com.JNative;

package com.JNative;

import java.io.UnsupportedEncodingException;

import org.xvolks.jnative.JNative;

import org.xvolks.jnative.Type;

import org.xvolks.jnative.exceptions.NativeException;

import org.xvolks.jnative.pointers.memory.MemoryBlockFactory;

public class Dll_Nat {

/**

* @param args

*/

public static void main(String[] args) throws NativeException ,IllegalAccessException{

// TODO Auto-generated method stub

Dll_Nat uc = new Dll_Nat();

String ret = null;

String result = uc.getNate("0023MBL_ZDtech_00001",

"0023MBL_SH_SVR00-01-02-03-04-05","ORGCODE",

"ttycode",0,"2008-08-25 15:51:55.025000", 1,

"218.201.33.11",50002,

"900001;00-01-02-03-04-05;1388*******~123435", ret);

System.out.println("轉(zhuǎn)換成功的字節(jié)數(shù)為："+result);

}

static JNative n = null;

static Pointer pointer;

public final int getNate(String trancode,

String clicode,

String orgcode,

String ttycode,

int brandid,

String reqstamp,

int reqseqno,

String svrip,

int svrport,

String reqmsg,

String resmsg) throws NativeException ,IllegalAccessException{

try{

n = new JNative("SwtThinClient.dll","rLachTran");

n.setRetVal(Type.INT);

int i =0 ;

n.setParameter(i++,trancode);

n.setParameter(i++,clicode);

n.setParameter(i++, orgcode);

n.setParameter(i++, ttycode);

n.setParameter(i++, brandid);

n.setParameter(i++, reqstamp);

n.setParameter(i++, reqseqno);

n.setParameter(i++, svrip);

n.setParameter(i++, svrport);

n.setParameter(i++, reqmsg);

n.setParameter(i++, resmsg);

n.invoke();

System.out.println(n.getRetVal());

return Integer.parseInt(n.getRetVal());

}catch(NativeException Ne){

System.out.println("NativeException: "+Ne.getMessage());

return -999;

}catch(IllegalAccessException Nen){

System.out.println("IllegalAccessException: "+Nen.getMessage());

return -888;

}

finally{

if (n != null)

n.dispose();

}

}

}

系統(tǒng)總是提示：不能鏈接服務(wù)器，而且C方法中的編碼是ASCII編碼，該問(wèn)題需要如何處理？請(qǐng)大家指教。

具體系統(tǒng)提示如下：
