mso-ascii-font-family:&quot;Times New Roman&quot;;mso-hansi-font-family:&quot;Times New Roman&quot;">为了能运行例程工程，必须拥有能够对例程创建或使用的所有文件和目录进行读写的权限。一般情况下，如果只拥有</span><span lang="EN-US">Jbuilder    
sample</span><span style="font-family:宋体;mso-ascii-font-family:
&quot;Times New Roman&quot;;mso-hansi-font-family:&quot;Times New Roman&quot;">子目录的读权限，就需要将例程拷贝至拥有读写权限的目录下。因为一些例程需要</span><span lang="EN-US">sample</span><span style="font-family:宋体;mso-ascii-font-family:&quot;Times New Roman&quot;;
mso-hansi-font-family:&quot;Times New Roman&quot;">目录中其它子目录中的文件，例如数据库文件。所以如果可能的话，推荐你创建整个例程树的拷贝。在其它例程目录下访问文件的例程会发一则消息指示例程期望文件的路径。</span></p>
<p class="MsoNormal" style="text-indent:21.75pt"><span style="font-family:宋体;
mso-ascii-font-family:&quot;Times New Roman&quot;;mso-hansi-font-family:&quot;Times New Roman&quot;">为了在这样一个环境下运行例程，要拷贝整个例程树至拥有读写权限的那个目录下。虽然从例程树中拷贝单个工程是可能的，但有的例程需要访问同级目录中的文件。这些例程已被修改设置为自动寻找在整个例程树层中相关的文件并在运行时显示一条消息指示这些文件所在路径正在被应用。</span></p>
<p class="MsoNormal" style="text-indent:21.75pt"><span style="font-family:宋体;
mso-ascii-font-family:&quot;Times New Roman&quot;;mso-hansi-font-family:&quot;Times New Roman&quot;">拷贝整个例程树的一个简易方法是使用命令</span><span lang="EN-US">cp    
–R</span><span style="font-family:宋体;mso-ascii-font-family:&quot;Times New Roman&quot;;
mso-hansi-font-family:&quot;Times New Roman&quot;">。例如，拷贝例程树至根目录中</span><span lang="EN-US">samples</span><span style="font-family:宋体;mso-ascii-font-family:&quot;Times New Roman&quot;;mso-hansi-font-family:
&quot;Times New Roman&quot;">子目录中，操作如下：</span></p>

<p class="MsoNormal" style="text-indent:21.75pt"><span lang="EN-US">% cp –R
