方法未实现错误Jboss4 - 不支持“multipart / form-data”

Question

我无法从SO中获得解决方案，因此发布。

我有一个示例JSP页面，该页面发布到实现和图像上传工具的供应商产品。

<script type="text/javascript">
function upload(){
document.forms[0].enctype="multipart/form-data"
document.forms[0].action="/upload"
document.forms[0].submit()
}
</script>

在监视请求的同时发布表单后，我收到以下响应，并且servlet默认处理输入内容类型= "application/x-www-form-urlencoded"

这些是请求标头：

响应标头如下：

我无法调试是否在Jboss 4的Tomcat中不支持"multipart/--"，或者我还有其他错误。
