一个很简单的java问题
小弟跪求高手解答问题 
公司要搞个可以收短信的短信猫程序 java的 小弟是弄php的不会java 现在二次开发包是有了 
里面有提示这样做
=========================================================
具体的操作步骤如下：
1、把smslib-3.3.3.jar、comm.jar与log4j-1.2.13.jar,ofbiz-entity.jar，放入到工程的lib中；
2、把javax.comm.properties放到%JAVA_HOME%/jre/lib下；
3、把win32com.dll放到%JAVA_HOME%/jre/bin下；还要放在%JAVA_HOME%/bin下；
4 把comm.jar放到%JAVA_HOME%/jre/lib/ext下
我添加成这样...

在原来的工程里的src文件夹里加入类 SendMessages.java

这个类是给的例子
