求救！！！Eclipse打包jar后运行报错！！！

xuranyao0416 2010-06-24 11:09:54

用Eclipse里的SWT插件做了一个导入EXCEL数据到数据库中的程序，打包成jar后，无法运行提示
Could not find the main clss:com.jxtele.xcgs.CardMain. Program will exit.
目前我有疑问：我的项目中用到了oracle的ojdbc14.jar，jxl.jar，swt.jar。是不是在打成jar包里要包含这三个jar包？目前的jar包里没有这上包，如果需要的话该怎么加进去。是否还需要其他的jar包。

楼主，我项目在eclipse里面能够运行，但是打成war包后，却报错，为啥？

需要依赖的JAR，导出为可执行JAR时，有选择是否一起打包。

也可以选择 Fatjar 或者Onejar插件

找不到main？，检查一下你的jar包里的主类的位置与包名一致 - -

如果要要在其他电脑上执行的话肯定得要那些jar吧
工程上右键-》export ->runnable jar file ->弹出的对话框下面的3个选项你看着选
- -这样就能把需要的jar导进去了。

我已经用fat jar 打包成功，并能运行了。谢谢各位！结贴散分

eclipse自带的打包功能不那么好用
LZ可以试试用Eclipse下的Fat-jar插件打包事半功倍啊
具体参考下http://www.360doc.com/content/09/0618/09/61497_3939628.shtml

估计是打包时出现一些细节问题，再多试试

以上是代码，由于超过输入字符数，没办法只好分两部分。等待高手来解决
