Why don't you use:
return super.getReader();
since HttpServletRequest allows you to call getReader() only once.
instead of:
return new BufferedReader(new StringReader(body));
I think, since the getReader() already has the handle to the body , a
second BuffredRedaer cannot be given.
Just try.

Subject: Filter for logging request content?
Hi all,
I want to build a logging filter that does not only log the
user/method/url but also the content of the request (i.e. for PUT
requests).
I easily can extract the content of the request via getReader().
The problem is that I always get:
java.lang.IllegalStateException: getReader() has already been called
for this request
I already tried to create a RequestWrapper (see below) but the
getReader() method of my wrapper never gets called and I still get
the above exception. Unfortunately I don't have access to the source
code of the called servlet.
Am I doing something wrong?
Does anybody have a possible reason/solution?
Any hint is much appreciated
Guido
chain.doFilter(new BodyWrapper((HttpServletRequest)request, body),
response);
// body is a String containing the body of the request
}
private class BodyWrapper extends HttpServletRequestWrapper {
private String body;
private BodyWrapper(HttpServletRequest req, String bo) {
super(req);
body = bo;
}
public BufferedReader getReader()
throws java.io.IOException {
System.out.println("BodyWrapper.getReader() called");
return new BufferedReader(new StringReader(body));
}
}
