问题是，类：au.com.bandaconsulting.databeans.IndexConfig包含在我的Databeans项目中，该项目被列为我的web项目"HadithSearcherWeb“的构建路径中的一个子项目，但我仍然收到上面的错误。当我右键单击"HadithSearcherWeb"，并选择"build path“、"configure build path"，然后转到"Order and Export”选项卡时，我在底部看到了"Databeans“项目，并将其选中。当我转到Projects选项卡时，我看到"Databeans“项目列在那里。有没有人看到我做错了什么？我是不是忽略了一个配置步骤？

整个子项目应该在web项目的/WEB-INF/lib中作为一个JAR文件结束。如何做取决于Eclipse的版本。在Eclipse3.6 (Helios)中，您需要在web项目属性的Deployment Assembly部分添加项目。在Eclipse 3.5 (Galileo)或更早的版本中，您需要在web项目属性的Java EE模块依赖项部分中添加项目。
