我在Eclipse中有两个Web项目：Framework和webxxx

在我的框架中，我有一些utils功能，例如复制，下载，上传等。

当我从webxxx调用下载方法时，得到了*java.lang.NoClassDefFoundError: javax/faces/context/FacesContext*.

如果将GerenciarArquivo类移至webxxx项目，则downloadFile方法可以正常工作。

框架：

public abstract class GerenciarArquivo{
...
public static void downloadFile(String filePath) throws IOException{
    FacesContext context = FacesContext.getCurrentInstance();
    HttpServletResponse response = (HttpServletResponse) context
                         .getExternalContext().getResponse();

WEBXXX项目：

GerenciarArquivo.downloadFile(abb.getPath());

这两个项目都有：

最佳答案

添加此依赖性，可以解决我的问题
