我是eclipse和tomcat的新手。我正在创建一个 servlet，它获取图像并将其保存在数据库中。
我正在使用 Jre 1.6 和 tomcat 7。为此，我使用了自定义库：

import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

现在我在部署我的项目时遇到了这个错误：

10 Jun, 2013 6:34:37 PM org.apache.catalina.core.ContainerBase startInternal
SEVERE: A child container failed during start
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/BIOMetric2]]

我使用了@MultipartConfig，现在工作正常。我使用了这段代码。...

import javax.servlet.annotation.MultipartConfig;
import javax.servlet.annotation.WebServlet;

...

Part filePart = request.getPart("img");
String imageName = filePart.getName(); 
InputStream in = filePart.getInputStream();
