Lakers were trounced -- Boo!
Frustrated that I couldn't manipulate a large XML file in CFMX, I
decided to write a Java program to read a text file, line by line.
Didn't need to --- found one by Daryl Banttari, at:
http://www.macromedia.com/devnet/server_archive/articles/
leveraging_java_classes_cf.html
This works fine -- takes about 3 seconds to read the 3.8 meg, 85,000
line file.
Interesting!
1) If it is so easy, why not implement it CFML? -- the CFMX/Java
hybrid solution means extra work when you install or maintain the app
-- you have to deal with Java source and class files.
2) The routine points out another deficiency in CFML (or at least
CFML's interface to other languages, like Java) -- CFML cannot
represent/recognize a Null! The programmer had to provide a
work-around.
Don't get me wrong, I am happy to find a solution, and being able to
interface Java is great!
But, IMO, this should not be necessary (to read a large file,
line-by-line) for a language as rich and powerful as CFML!
