从Adobe LC HTML5表单提交时，无法使用Java JSP从InputStream检索XML

I developed a simple HTML5 form using Adobe LiveCycle ES4 + SP1 which will submit to Java JSP. Also, I developed simple JSP to retrieve the submitted XML from request InputStream.

我使用Adobe LiveCycle ES4 + SP1开发了一个简单的HTML5表单,它将提交给Java JSP。此外,我开发了简单的JSP来从请求InputStream中检索提交的XML。

What I am getting on the server is the concatenated values of the form fields. See snapshots below for more details.

我在服务器上获得的是表单字段的连接值。有关详细信息,请参阅下面的快照。

The following lines of code are used to submit the HTML5 to the JSP which are placed under the click event of the "Save" button:

以下代码行用于将HTML5提交到JSP,这些代码位于“保存”按钮的单击事件下:

var theBtnSubmit = cmdSubmitForm.resolveNode("#event").submit;
var theTarget = form_config.server_url.rawValue + "?" + "action=save" + "&form_id=" + form_config.form_id.rawValue + "&section_id=" + form_config.section_id.rawValue;
theBtnSubmit.target = theTarget;
cmdSubmitForm.execEvent("click");

The following lines of code are used to get the InputStream and convert to string:

以下代码行用于获取InputStream并转换为字符串:

ServletInputStream ris = request.getInputStream();  
String theString = IOUtils.toString(ris); 

The problem:
On the server, I am unable to retrieve the form fields and values in XML format. What I am getting is the concatenated values of the fields which are filled in the form.

问题:在服务器上,我无法检索XML格式的表单字段和值。我得到的是填写在表单中的字段的连接值。

Actually, the above method is fine, the only thing is that I had to escape the XML output using the following lines of code:

实际上,上面的方法很好,唯一的问题是我必须使用以下代码行来转义XML输出:

<%@page import="org.apache.commons.lang3.StringEscapeUtils" %>
...
String theString = IOUtils.toString(ris, Charset.forName("UTF-8"));
theString = StringEscapeUtils.escapeXml10(theString);
out.print("input stream in string format : " + theString + "<br/>");
