jbpm上传打包好的zip文件，然后上传完说发布流程文件失败，求大神解答

工具：MyEclipse10.0 jbpm4.4 数据库版本是Mysql5.1

下面是jsp页面代码
jsp页面代码
<%@page import="java.util.zip.ZipInputStream"%>
<%@page import="java.io.File"%>
<%@page import="java.io.FileInputStream"%>
<%@page import="java.io.InputStream"%>
<%@page import="org.jbpm.api.RepositoryService"%>
<%@page import="org.jbpm.api.Configuration"%>
<%@page import="org.jbpm.api.ProcessEngine"%>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

上传
<br> function readFile(obj) {<br> document.getElementById("file").value = obj.value;<br> }<br>

<% request.setCharacterEncoding("UTF-8");
String deployFile = request.getParameter("processDef");
if (deployFile != null && deployFile != "") {
//必须使用的，流程引擎
ProcessEngine processEngine = Configuration.getProcessEngine();
RepositoryService repositoryService =processEngine.getRepositoryService();
try {
String file = deployFile;
//将ZIP文件封转到IO流里
InputStream is = new FileInputStream(new File(file));
ZipInputStream zis = new ZipInputStream(is);
//将ZIP流程文件发布到pvm（流程虚拟机中，他会把ZIP包中的xml文件和png图片存储到数据库中）
repositoryService.createDeployment().addResourcesFromZipInputStream(zis).deploy();
zis.close();
is.close();
out.println("发布流程成功
");
out.println("返回
");
} catch (Exception e) {
e.printStackTrace();
out.println("发布流程失败");
}
}
%>
可直接发布zip文件

发布流程文件

要上传的流程文件
xml代码
<?xml version="1.0" encoding="UTF-8"?>

上传完失败后，出现下面错误
