jsf-java。lang.NoClassDefFoundError:javax/faces/context/FacesContext

Question

我在Eclipse中有两个web项目：框架和webxxx

在我的框架中，我有一些功能，比如复制、下载、上传等等

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

如果我将GerenciarArquivo类移动到webxxx项目，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：

Answer 1

加上这个依赖，这就解决了我的

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

<dependency>
     <groupId>javax</groupId>
     <artifactId>javaee-web-api</artifactId>
     <version>6.0</version>
     <scope>provided</scope>
</dependency>
