关于java的兼容性问题

[hugos]

我用forte for java 做applets, 如果applets用AWT开发的话，浏览器可以初始化applets. 但是如果applets用到swing(import javax.swing.*)的东西，浏览器就找不到class, 这是怎么回事？
我的环境：win2000server + apache + forte for java 3E + java plugin 1.3.1 + java sdk 1.3.1;
怎么样才能够用上swing?

html只要像如下修改，即可：
<object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
codeBase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0"
width=300
height=320
align=center>
<param name="code" value="*****.class">
</OBJECT>


或者下载jre for 98,win2000,xp,安装，可不用修改html

plugin我已经有了。
把你的代码加进去之后，好像启动了两个java console.

[hugos]

jre 早就装了。
还是不行啊！

[gdsean]

编译不通过，org.netbeans.lib.awtextra?是什么冬冬？

[hugos]

呵呵，org.netbeans.lib.awtextra是forte的wizard自动生成的。我也不知道是什么东东啊！

[hugos]

同志们，帮帮忙吧
难道用forte for java 的人太少了？
用AppletViewer可以啊，用IE就找不到。
错误提示：load: class mobilet not found

[gdsean]

设置classpath,把mobilet.class所在的目录写进去
或者看看java console的工作目录在什么地方，把
mobilet.class拷贝进去

[hugos]

to :gdsean(摇滚java)　
但是为什么AWT做的applets就不用设置工作目录？

[hugos]

谢谢各位，问题解决了，散分！
需要正确的设置CLASSPATH环境变量。就可以了。
但是对于INTERNET客户，怎么办？ 不能让他们手动的设吧，根本就不可能。有没有什么好的方法？
