I am using java JDK 7 in my attempt to build cocoon 2.1.10 on Windows 2008 R2 for eventual deployment in Tomcat 7. I have downloaded the cocoon source files, unzipped them, set my JAVA_HOME variable and then tried to run the build.bat file provided. I get 11 different compilation errors.

I also tried using "build war" on my command line and this yielded the same result.
Is this an issue with the JDK I am using or is there something else that I need to be looking at? This is my first attempt at building and deploying cocoon, I could be missing something obvious.

The deprecated, proprietary com.sun.image.jpeg.codec package has been removed from JDK 7 (see this official official JDK7 compatibility note). Hence your compilation problem.
Since patching the Cocoon source may not be an option in your situation, the shortest path for you might be to compile using JDK 6 (or earlier, the Cocoon 2.1 series require "Java 1.3 or later").
(But if it is, as you seem to require specific Cocoon and JDK versions, you may want to have a look at the SO Q&A on How to replace com.sun.image.codec.jpeg.JPEGImageEncoder with calls to the standard Java Image I/O API)
Another option might be to look at a separate distribution of the com.sun.image.jpeg.codec package to include in you build (and possibly runtime) classpath. I'm unsure about the availability (and the ease of use) of this option. Anyhow I wouldn't recommend digging into it unless all other path have proven to be dead-ends...
