You'd need to write some custom code. You can get the data directly via JMX or using HTTP and the JMX proxy (part of the Manager app). Whichever you use, be sure to secure it.

Something like this bufOutStream = new

... and how are you writing to the BufferedOutputStream?
So I end up calling this method for most of the writes that are
performed for binary IO.
@Override
public synchronized void write(byte[] b, int off, int len)
throws IOException {
long bTime = System.currentTimeMillis();
super.write(b, off, len);
long aTime = System.currentTimeMillis();
timeDelta += aTime-bTime;
++numWrites;
updateSNMPValue(bWrote);
}
Im not clear when I call response.addHeader and response.sendError,
what or if the BufferedOutput stream IO is called by Tomcat Coyote.
When I debug the Web App I see that BufferedOutputStream underlying
OutputStream (protected) is in fact a CoyoteOutputStream (I can access
this object) and it contains a protected object called
org.apache.catalina.connector.OutputBuffer. I would dearly like to
get at this objects data but I cannot as its protected, this contains
the headers and details about the stream and its state.
Is there a way to dump out this object OutputBuffer details. Is there
any debug logs I can enable here?
Thanks

I must have misunderstood your question. What do you mean exactly by
the question and how are you writing to the BufferedOutputStream?
I call the write method above when writing out the binary data in the
response body. Is this the information you require or am I missing
something? Apoligises if Im being silly on this.

So far you've shown me that you wrap the output stream, and how the

You haven't actually posted the part of the code where you write your

Replace one class of a running webapp
Hello all, I've deployed a JSF-Project to a Tomcat Server. The problem is that I need to make a small code change affecting only one class. There are currenty many users logged into the system, therefore, I don't want to deploy the whole webapplication. The question is, can I just replace this class in a running webapp given that I'm using the same Tomcat version for a local deployment?
