I believe it is because to read input & write output from the client,
servlets use stream classes which inherit from stream classes in the java.io
package.
Some of the methods of these servlet streams throw IOExceptions themselves.
These streams are retrieved by a servlet using request.getInputStream() and
response.getOutputStream().
Because the servlet container creates the request and response objects and
passes them to the servlet, I think it makes sense that if it's handing out
bad streams to the servlets it needs to find out about it.
@See
javax.servlet.ServletRequest.getInputStream()
javax.servlet.ServletInputStream
javax.servlet.ServletResponse.getOutputStream()
javax.servlet.ServletOutputStream
java.io.InputStream
java.io.OutputStream
in the APIs for more info.
