Summary: HttpServletRequest.getInputStream is null with
Content-Type: application/x-www-form-urlencoded
Product: Tomcat 6
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Keywords: APIBug
Severity: critical
Priority: P2
Component: Servlet & JSP API
AssignedTo: dev@tomcat.apache.org
ReportedBy: neng1...@yahoo.com
When client send xml message with Content-Type:
application/x-www-form-urlencoded. if you do "request.getParameter("message")"
first. then subsequent call request.getInportStream()return an empty
inputStream (not null, just not data).
Note:
1. If client set Content-Type: text/xml in request HTTP header, no problem.
2. If you do not do "request.getParameter("message")";
request.getInportStream() works. (can read the body data).
3. I understand the Content Type and client should not set
"x-www-form-urlencoded" if they just send XML message in HTTP body.
But, I still think it is bug. request.getInportStream() should be able to read
the data in HTTP body regardless what Content Type is.
