Subject Re: native2ascii and JDK/JRE
Date Fri, 12 Sep 2014 20:35:59 GMT
Thanks, Martin,

The DITA Open Toolkit is a bit of on odd duck. It uses Ant, but not to build 
Java, so the JDK isn't required to run the OT. (People just get used to the 
constant "missing tools.jar" messages.) As I said, the DITA OT only requires a JRE.

So yes, you're correct, if the user has the JDK, adding tool.jar to the 
classpath is a good thing to do (and solves my elegance question).

However, absent the JDK, the situation is a bit stickier.
