Java LWJGL小程序NoClassDefFound

Question

I'm trying to use my java applet on a html document but It just keeps giving the same errors over and over again. 我试图在html文档上使用我的java applet，但是它总是不断地给出相同的错误。 I'm using eclipse. 我正在使用日食。 When i debug/run the applet it all works fine, but when I export it to a jar file and try to use it with a html document it gives this error: 当我调试/运行applet时，一切正常，但是当我将其导出到jar文件并尝试与html文档一起使用时，出现此错误：

java.lang.NoClassDefFoundError: org/newdawn/slick/opengl/Texture

Here is my java code: http://pastebin.com/B3R6nj1a 这是我的Java代码： http : //pastebin.com/B3R6nj1a

This is what the .jar file contains: 这是.jar文件包含的内容：

-lib
  -jars
    lwjgl.jar
    lwjgl_util.jar
    slick-util.jar
  -natives-win
    *all the dlls*

-META-INF
  -*files*

-res
  grass.png
  wood.png

.classpath
.project
Camera.class
Main$1.class
Main$2.class
Main.class

I do have everything right in the build path from my project. 我确实在我的项目的构建路径中拥有一切。 (So added the three external jars. And added native-win to lwjgl.jar) （因此添加了三个外部jar。并且向lwjgl.jar添加了native-win）

This is my html code: 这是我的html代码：

<html>
<head>
</head>
<body>
   <applet archive='3dtest.jar' Code='Main' width = "640" height = "480"></applet>
</body>
</html>

I've also tried to change "Code='Main' " to "Code='Main.class'" also didn't work. 我也尝试将“ Code ='Main'”更改为“ Code ='Main.class'”也不起作用。

Does anybody has any idea why I'm getting the error? 有人知道我为什么要出错吗？ Thanks in advance. 提前致谢。

Answer 1

This is what the .jar file contains: 这是.jar文件包含的内容：
 -lib -jars lwjgl.jar ... 

Those Jars should not be there. 那些罐子不应该在那里。 They should be separate Jars on the site referenced something like this: 它们应该是站点上引用类似以下内容的单独Jars：

<html>
<head>
</head>
<body>
<applet 
  archive='3dtest.jar,lwjgl.jar,lwjgl_util.jar,slick-util.jar,all_dlls.jar..' 
  code='Main' 
  width="640" 
  height="480">
</applet>
</body>
</html>

That is presuming the HTML is in the same directory as all the Jars. 假定HTML与所有Jars位于同一目录中。

Answer 2

You need to post relevant code, not everything and hope someone will pick through it all. 您需要发布相关代码，而不是所有内容，并希望有人能仔细阅读所有内容。

java.lang.NoClassDefFoundError: org/newdawn/slick/opengl/Texture means that class is not present in your classpath. java.lang.NoClassDefFoundError: org/newdawn/slick/opengl/Texture表示您的类路径中没有该类。

Answer 3

You need to make sure your applet is packaged properly when deploying it. 您需要确保在部署小程序时正确打包了该小程序。 See http://docs.oracle.com/javase/tutorial/deployment/applet/deployingApplet.html 参见http://docs.oracle.com/javase/tutorial/deployment/applet/deployingApplet.html
