Subject RE: Tomcat JRE vs JDK Issue
Date Tue, 16 Nov 2004 15:41:34 GMT
Due to other programs that we install on the client machine, the JRE is
installed.  I was hoping to just use that in order to minimize the changes
to our other programs and setups.  Do you know where I could find more
information about using tools.jar?

Correct me if I'm wrong.
 
One of the things the JDK brings that the JRE does not is tools.jar
which contains com.sun.tools.javac, which is needed to compile JSPs.
 
It might be possible to use the JRE as long as you have tools.jar from
the JDK somewhere in your classpath. It seems like I saw a thread
related to this a while ago, although I don't know if it works. 
 
Is there a compelling reason to want to use the JRE rather than the
full JDK?

Chris,

JSP pages get compiled into bytecode (as Yoav just said) as they are
requested.  So, the server requires the SDK, including javac to do the
compiling.
