Question

当我将 h：inputFile 与 f：ajax 一起使用并尝试在 Apache-tomcat-7.0.8 上部署时，发送AJAX请求时，tomcat服务器抛出以下异常。任何人都可以帮我解决这个问题。感谢。

关于Tomcat的javax.servlet.ServletException

com.sun.faces.renderkit.html_basic.FileRenderer decode
SEVERE: Unable to get parts for frmIndex:file
javax.servlet.ServletException: org.apache.tomcat.util.http.fileupload.FileUploadBase$InvalidContentTypeException: the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is application/x-www-form-urlencoded;charset=UTF-8

JSF页面

<h:form id="frmIndex" enctype="multipart/form-data">

   <h:inputFile id="file" value="#{indexController.file}"/>

   <h:commandButton value="Upload" action="#{indexController.postTrailDetail}">
      <f:ajax execute=":frmIndex:tUpostPanelGroup" render="@all"/>
   </h:commandButton>

</h:form>

Java控制器

@Component
@SessionScoped
@Scope("session")
@Qualifier("indexController")
public class IndexController implements Serializable {

  private Part file;

  public void postTrailDetail() {

   if(file != null) {} 

  }

  // Getter and Setter for Part

}

尝试不用f：ajax标签？使用ajax时，我遇到此标记和错误消息的问题。没有ajax，一切都很好。

JSF 2.2，h：带f：ajax的inputFile组件
