Sun WTK预验证在J2ME中失败- java/lang/NoClassDefFoundError

Question

我已经编写了ANT脚本来预先验证类。

 <property name="wtkHome" location="C:/WTK2.5.2"> </property>
 <property name="midp_lib" value="${wtkHome}/lib/midpapi21.jar"></property>
   .... 
  ........
<property name="build" value="build"/>
.....
   ......    

    <target name="preverify">
            <mkdir dir="${build}/preverified"/>
                <exec executable="${wtkHome}/bin/preverify">
                  <arg line="-classpath ${wtkHome}/lib"/>
             (or) <arg line="-classpath ${midp_lib}"/>
                  <arg line="-d ${build}/preverified"/>
                  <arg line="${build}/classes"/>
                </exec>
        </target>

当上面的脚本执行时，它不能在类路径中找到midp类，所以它显示了错误，

[exec] Error preverifying class first.MCCanvas
[exec] java/lang/NoClassDefFoundError: javax/microedition/lcdui/Canvas
[exec] Result: 1

但是所需的库在类路径中，请注意，对于MIDlet和Canvas类，编译是很好的！

尝试使用反斜杠"\“

<arg line="-classpath C:\WTK2.5.2\lib\midpapi21.jar"/>
