I got this error while compiling ucspi-tcp . The solution was to move #include <errno.h> from error.c to error.h .
The following also works:
echo gcc -O2 -include /usr/include/errno.h > conf-...
The reason was explained in http://cr.yp.to/docs/unixport.html#errno

You can use the system call from the os module to execute an external program:
>>> import os
>>> os.system(the_command_line_st...
However, the path to the executable contains a space character, the system call treats the strings after the first space as arguments, causing an error.
Python doc recommends the use of the subprocess module:
The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function.
For example, using wget to get the google home page:
>>> from subprocess import Popen, PIPE

http.keepAlive (default: true)
Indicates if keep alive (persistent) connections should be supported. Persistent connections improve performance by allowing the underlying socket connection be reused for multiple http requests.
The default is true and thus persistent connections will be used with http 1.1 servers. Set to 'false' to disable the use of persistent connections.
http.maxConnections (default: 5)
If HTTP keep-alive is enabled, this value is the number of idle connections that will be simultaneously kept alive, per-destination.

Spring MVC 3.1 can send either JSON or HTML response on the same URL, depending on the type of response requested. With this mechanism, a page can be sent when directly requested from a link, but a JSON response can be sent in response to an AJAX request. This is the controller code:
package com.example; import java.util.Map; ... In the above example, JSON response will be sent when the HTTP request contains header "Accept: application/json". HTML response will be sent then the header is "Accept: */*", or "Accept: text/html", or anything else. You can add a limitation that the HTML response does not produce "application/json". But then the question is which response will be sent when the HTTP header is "Accept: */*"? Both methods will...

Thanks Dr.Xi, I was having a tough time changing the deployment context path of my web-app using the
so-called context.xml file under /META-INF, it dint work (tomcat documentation at http://tomcat.apache.org/tomcat-6.0-doc/config/context.html , seemed pretty sure it would :()
But I have one question, as changing server.xml is too instrusive for every web-app you build, is there any other way of pushing this configuration to one of the application specific files ?
thanks,
Venky
