org.apache.commons.fileupload.FileUploadBase$InvalidContentTypeException

org.apache.commons.fileupload.FileUploadBase$InvalidContentTypeException求助
org.apache.commons.fileupload.FileUploadBase$InvalidContentTypeException: the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is null
代码本身是没有问题的，但是C++的项目sso访问我写的java项目的时候按照原有的方式找不到对应的servlet，所以还需要sso访问servlet，就在sso访问servlet的时候出错了，请大牛指点下

页面代码

HTML code

<f:loadBundle basename="com.webapp.resource.WebAppResource"var="resource" />            <h:form id="fromUpload" enctype="multipart/form-data" onsubmit="startProgress()">                                      里边是内容……            </h:form>

项目本身访问Servlet的js代码

JScript code

function submitUpload(){          usersFunction.getUsernameAndPassword(function(data){  if(data.length > 3){  var fromUpload = document.getElementById("fromUpload");  fromUpload.action='http://192.168.0.153:8080/users/servlet/SSOAuth?PWSecurity=true&username='        +data.split(",")[0]+'&password='+data.split(",")[1]+'&goto=../servlet/addErrorMsg？           returnUrl='+'addError.faces';      fromUpload.method="POST";      fromUpload.submit();  }});}

SSO访问Servlet的js代码

JScript code

function submitUpload(){          usersFunction.getUsernameAndPassword(function(data){  if(data.length > 3){  var fromUpload = document.getElementById("fromUpload");  fromUpload.action='http://192.168.0.153:8080/users/servlet/SSOAuth?PWSecurity=true&username='        +data.split(",")[0]+'&password='+data.split(",")[1]+'&goto=../servlet/addErrorMsg？           returnUrl='+'addError.faces';      fromUpload.method="POST";      fromUpload.submit();  }});}

[解决办法]
onsubmit="startProgress()"
换成
action="startProgress()"
试试。
