Try

C:\jetty\jetty-6.1.11\jetty-6.1.11>mkdir source
C:\jetty\jetty-6.1.11\jetty-6.1.11>move HelloServlet.java source
C:\jetty\jetty-6.1.11\jetty-6.1.11>cd source
C:\jetty\jetty-6.1.11\jetty-6.1.11\source>javac -d ..\webapps\hello\WEB-INF\classes -classpath ..\lib\servlet-api-2.5-6.1.11.jar;. HelloServlet.java
C:\jetty\jetty-6.1.11\jetty-6.1.11\source>echo 'Is it there?'

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

you have wrong extra path in your javac parameters (C:\jetty\jetty-6.1.11\jetty-6.1.11\lib\servlet-api-2.5-6.1.11\servlet-api-2.5-6.1.11.jar)

try this one
C:\jetty\jetty-6.1.11\jetty-6.1.11>javac -cp .\lib\servlet-api-2.5-6.1.11.jar HelloServlet.java

The problem is that won't put the class file where it's meant to be. OK, so you can copy the class file or move it but
a. there's no need
b. if you have packages involved (which you should normally) that won't be easy

If you want to continue at the command line (which personally i think is a good idea), you might like to look at using Ant, which will cope as the classpath gets bigger
