Hi,
I try to create a filter which is reading the request and response data out.
The Response is fine I can read the whole envelope.
For the Request I can read all the Parameters, Attributes, Cookies.
But if I try to read the body then it hangs.
With the following message:
2004-04-22 08:25:21 StandardWrapperValve[AxisServlet]: Servlet.service() for servlet AxisServlet threw exception
java.lang.IllegalStateException: getReader() has already been called for this request
I have tried this also with the getInputstream the same effect also tried it after the chain.doFilter invokation also the same ....
I have no Idea at the moment .........
here is the code for my filter and the request wrapper:
public void doFilter(final ServletRequest request, final ServletResponse response, FilterChain chain) throws IOException, ServletException
{
BasicRequestWrapper requestWrapper = new BasicRequestWrapper((HttpServletRequest)request);
String requestString = requestWrapper.toString();
log(requestString);
OutputStream out = response.getOutputStream();
ByteArrayResponseWrapper responseWrapper = new ByteArrayResponseWrapper((HttpServletResponse) response);
chain.doFilter(requestWrapper, responseWrapper);
out.write(responseWrapper.getData());
out.close();
return;
}
public class BasicRequestWrapper extends HttpServletRequestWrapper {
public BasicRequestWrapper(HttpServletRequest request){
super(request);
}
private String getBodyAsString(){
StringBuffer buff = new StringBuffer();
buff.append(" BODY_DATA START [ ");
char[] charArr = new char[getContentLength()];
try{
BufferedReader reader = new BufferedReader(getReader());
reader.read(charArr, 0, charArr.length);
reader.close();
}catch (IOException e) {
e.printStackTrace();
}
buff.append(charArr);
buff.append(" ] BODY_DATA END ");
return buff.toString();
}
public String toString(){
return getBodyAsString();
}
}
Many thanks in advance ......
Levent
