JSP页面上的JUpload问题
我得到：
load: class wjhk.jupload2/JUploadApplet.class not found.
java.lang.ClassNotFoundException: wjhk.jupload2.JUploadApplet.class

Exception: java.lang.ClassNotFoundException: wjhk.jupload2.JUploadApplet.class
在java consule上。
调用小程序
<applet
code="wjhk.jupload2/JUploadApplet.class"
codebase="\EAMAPP84\data\docuploads\ROADS\NoamTest"
archive="JUpload.jar"
width="650"
height="400">
<param name="actionURL"
value="\\test1\EAMAPP84\data\docuploads\ROADS\NoamTest">
</applet>
当 jar 位于给定目录中时， 。 奇怪的是，当我使用它创建一个简单的 html 文件时，它可以工作，但是当我在 jsp 页面中使用它时，我收到此错误。
有人吗？

Exception: java.lang.ClassNotFoundException: wjhk.jupload2.JUploadApplet.class
on the java consule.
the applet is called:
<applet
code="wjhk.jupload2/JUploadApplet.class"
codebase="\EAMAPP84\data\docuploads\ROADS\NoamTest"
archive="JUpload.jar"
width="650"
height="400">
<param name="actionURL"
value="\\test1\EAMAPP84\data\docuploads\ROADS\NoamTest">
</applet>
while the jar is sitting in the given directory.
the wierd thing is, when i create a simple html file using this it works, butwhen using it in my jsp page i get this error.
anyone?

code属性应指向 类的完全限定名称（与普通 Java 类的import语句中使用的名称相同）。顺便说一下，例外情况还暗示：
（
.class部分根本不属于那里）以及这里：
（注意
/class.class部分显然是错误的）The
codeattribute should point to the fully qualified name of the class (the same as you would use inimportstatement of a normal Java class).The exception is by the way also hinting that:
(the
.classpart doesn't belong there at all)and also here:
(note the
/class.classpart which is obviously wrong)应该是..
Should probably be..
