GAE：java.lang.NoClassDefFoundError：com / google / appengine / api / blobstore / BlobstoreServiceFactory [英] GAE : java.lang.NoClassDefFoundError: com/google/appengine/api/blobstore/BlobstoreServiceFactory

问题描述

请帮助我。我使用blob store来保存图像，并且在我的本地环境中工作得很好。但是当我部署相同的代码时，它会抛出异常：java.lang.NoClassDefFoundError：com / google / appengine / api / blobstore / BlobstoreServiceFactory

我是使用GAE 1.8.4

解决方案

很可能， appengine-api.jar 从 war / WEB-INF / lib / 文件夹中丢失。如果您使用Eclipse，请单击问题标签。你可能会看到一个警告，说这个jar在服务器上不可用。右键单击此警告，选择QuickFix，选择复制...选项。或手动将此jar复制到此目录。

Kindly help me with this. I am using blob store for saving images and it is working perfectly fine on my local environment. But when I deploy the same code the cloud it is throwing me the exception : java.lang.NoClassDefFoundError: com/google/appengine/api/blobstore/BlobstoreServiceFactory

I am using GAE 1.8.4

解决方案

Most likely, appengine-api.jar is missing from your war/WEB-INF/lib/ folder.

If you use Eclipse, click on the Problems tab. You may see a warning saying that this jar is not available on a server. Right click on this warning, select QuickFix, select "Copy..." option. Or copy this jar to this directory manually.
