java 嘉讯短信接口问题

代码如下，是嘉讯短信接口，我想先测试一下，

我就导入了一个jar包，

ImApi.jar

为什么我总是连接失败，小白一个，

问问前辈，这种连接方式是否可行

package testSendMessage;

import com.jasson.im.api.APIClient;

public class TestMessage {
private String host = "***.**.**";
private String apiId = "29";
private String name = "**";
private String pwd = "**";
private APIClient handler = new APIClient();
public void init()
{
int connectRe = handler.init(host,name,pwd,apiId);
if(connectRe == APIClient.IMAPI_SUCC)
System.out.println("初始化成功");
else if(connectRe == APIClient.IMAPI_CONN_ERR)
System.out.println("连接失败");
else if(connectRe == APIClient.IMAPI_API_ERR)
System.out.println("apiID不存在");

}

public void send_ms(){
    handler.sendSM("13811114909", "测试内容", -1);
}

public static void main(String[] args) {
    TestMessage tm = new TestMessage();
    tm.init();
    tm.send_ms();
}

}
