smslib 包使用

使用smslib包详解

1.配置comm.jar包

     1)   Copy win32com.dll to your <JDK>\bin directory.

C:\>copy c:\commapi\win32com.dll to c:\jdk1.1.6\bin

 

      2)   Copy comm.jar to your <JDK>\lib directory.

C:\>copy c:\commapi\comm.jar c:\jdk1.1.6\lib

 

 

      3)   Copy javax.comm.properties to your <JDK>\lib directory. 

 

      4)   C:\>copy c:\commapi\javax.comm.properties c:\jdk1.1.6\lib

            The javax.comm.properties file must be installed. If it is not, no ports will be found by the system. 
           Add comm.jar to your classpath (do not do this step for a JRE installation).

    

           If you don't have a classpath defined: 

      C:\>set CLASSPATH=c:\jdk1.1.6\lib\comm.jar

          If you already have a classpath defined: 

      C:\>set CLASSPATH=c:\jdk1.1.6\lib\comm.jar;%classpath%

    5)特别注意在myeclipse建立工程时，jre选择java的 不要使用myeclipse的否则报端口没找到错误  javax.comm.NoSuchPortException

2.建立工程导入lib包 comm.jar   log4j-1.2.13.jar   smslib3.2.2.jar

 

3.查看端口是否配置成功

  Enumeration en = CommPortIdentifier.getPortIdentifiers();
  CommPortIdentifier portId;
  while (en.hasMoreElements())
  {
   portId = (CommPortIdentifier) en.nextElement();
  if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL){
   System.out.println(portId.getName());
  }
  }

成功打印你机器的端口

不成功不显示

4.使用
