In a POST the data *should* be in the request body, if I understand things
correctly. In 3.1.1 that's the way things worked. In 3.2, if I try to
read the request body using the stream provided by the
request.getInputStream call, I get an empty string and the XML that was
sent in the lzpostbody shows up as a strangely named request parameter.
For example, I do the following to write out the parameters:
for (Enumeration enumx = req.getParameterNames();
enumx.hasMoreElements();) {
String name = (String) enumx.nextElement();
String parameterValue = (String) req.getParameter(name);
System.out.println("Name: " + name);
System.out.println("Value: " + parameterValue);
}
With the XML given below, I see the following output:
Name: <ds><foo><bar
Value: id="25030"/></foo></ds>
Reading the entire content of the input stream via req.getInputStream()
yields blank. This is under Laszlo 3.2. Under 3.1.1 there are no
parameter values and the req.getInputStream() produces the expected value.
