<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left" align=left>其次：把comm.jar</SPAN>復制到<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>JSDK</FONT></SPAN>安裝目錄的<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>jre1.6.0\lib\ext\</FONT></SPAN>下，并把<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>comm.jar</FONT></SPAN>包加在<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"></SPAN></FONT></FONT></P>

<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left" align=left>CLASSPATH</SPAN>下，把<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>javax.comm.properties</FONT></SPAN>文件復制到<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>JSDK</FONT></SPAN>安裝目錄的<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>jre1.6.0\lib</FONT></SPAN>下，<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"></SPAN></FONT></FONT></P>

<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-ALIGN: left" align=left>在建立好一個空的JAVA</SPAN>的工程時把<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>comm.jar</FONT></SPAN>復制到<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>lib</FONT></SPAN>目錄下并加載在工程里，把<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>win32com.dll</FONT></SPAN>復制到工程的根目錄下或者復制到<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>JSDK</FONT></SPAN>安裝目錄的<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"><FONT face=Calibri>jre1.6.0\bin</FONT></SPAN>目錄下。<SPAN lang=EN-US style="mso-bidi-font-size: 10.5pt"></SPAN></FONT></FONT></P>
