How to set classpath in manifest file , while creating JAR from eclipse?
提问by Hippo
I am trying to creat JAR file through eclipse. I read some of the threads from
stackoverflow as well as other forums. But nothing is helping.
stackoverflow 以及其他论坛。但没有任何帮助。
I have created a separate manifest file like this one.
我创建了一个像这样的单独清单文件。
Manifest-Version: 1.0
Main-Class: Main
Class-Path: gnujaxp.jar iText-2.1.5.jar jcalendar.jar jcommon-1.0.16.jar jfreechart-1.0.13.jar jfreechart-1.0.13-experimental.jar jfreechart-1.0.13-swt.jar junit.jar servlet.jar swtgraphics2d.jar tinyos.jar
I have put all this jars in same project folder.
我已将所有这些罐子放在同一个项目文件夹中。
While exporting i am exporting all resources (meants this jar files also.)
导出时我正在导出所有资源（也意味着这个 jar 文件。）
But still i am getting noclassdeffound error when my application tries to load any one of the jar included.
但是当我的应用程序尝试加载包含的任何一个 jar 时，我仍然收到 noclassdeffound 错误。
M i wrong anywhere ..
我哪里都错了..
Thanks in advance.
提前致谢。

If you are using eclipse >=3.4 try "export as runnable jar file" it should generate it correctly.
如果您使用的是 eclipse >=3.4，请尝试“导出为可运行的 jar 文件”，它应该会正确生成它。
Otherwhise you can provide your own manifest file in the export as jar dialog.
否则，您可以在导出为 jar 对话框中提供您自己的清单文件。

I get this error and find that my manifestneeds a space after the jars in the class-path. This includes the ones at the end of the line and end of list, otherwise it mashes them together.
我收到此错误，并发现我manifest需要在 .jar 文件后留一个空格class-path。这包括行尾和列表末尾的那些，否则会将它们混在一起。

Be sure to add an empty line at the end of your Manifest file.
请务必在清单文件的末尾添加一个空行。
