Subject Re: Calling Ant from Java: An example please ?
Date Wed, 13 Feb 2002 19:57:57 GMT
Yes, I am TRYING to do that.
But I am failing miserably.
There are NO EXAMPLES on how to do this; there is only Javadoc
on the API itself (with very little extra explanatory text).

OK, maybe I am not being specific enough here.

Here is the java code that I have written that attempts
to compile a "Hello, world" java file:
http://home.attbi.com/~theriddells/CompileIt.java

And here are the results that I get:
http://home.attbi.com/~theriddells/results.txt

(Sorry for the links, I felt they were too long to be
directly quoted here.)

Thoughts ?  Help ?

Thanks
