java.lang.NoClassDefFoundError:javax / faces / context / FacesContext

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,如复制,下载,上传等......

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

如果我将GerenciarArquivo类移到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 PROJECT:

GerenciarArquivo.downloadFile(abb.getPath());

两个项目都有:

添加此依赖项,这解决了我的问题

  

class not found exception:javax.faces.context.facesContext。

转到您的Oracle-&gt;中间件 - &gt;模块 - &gt;并复制javax.jsf_1.2.0.1.jar并将其粘贴到您的EAR-&gt; APP-INF-&gt; lib文件夹中,然后重新启动您的服务器。为我工作
