If you've ever written servlets, you know what a tremendous pain it is to write and maintain all those out.println() statements. JSP was designed to allow more HTML-centric (aka presentation-side) people to create pages that get turned into servlets that are compiled into bytecode for the java interpreter to interpret. If you peek around the work directory, you'll find an XXX_jsp.java and an XXX_jsp.class file for every JSP.
That's why a JRE isn't enough-- you need a compiler from the JDK to compile the JSP into servlets.
Phew!

Chris:
I think TC requires the JDK (not just the JRE) so that it can compile JSPs. If this doesn't make sense, I can explain further.

does the client machine have JAVA_HOME as an environment variable?

I'm trying to run Tomcat 5.0.28 on W2k client machine. On my machine, it runs fine, with no problems. But when I copy it over to the client machine, which has the 1.4.2_05 JRE on it, Tomcat won't run, and says that it requires the JDK. Why is this, and is there a workaround, or do I have to install the JDK? I don't remember having this issue with 4.x. Is it 5.x specific? TIA.
