我在 Eclipse 中有两个 Web 项目:Framework 和 webxxx
在我的框架中,我有一些 utils
复制、下载、上传等功能...
当我从webxxx
调用下载方法时我得到了*java.lang.NoClassDefFoundError: javax/faces/context/FacesContext*.
如果我搬家GerenciarArquivo
类到 webxxx 项目 downloadFile 方法工作正常。
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());
两个项目都有:
