Can you prevent StringTemplate output to stderr?

Question

Im currently using the following to output to a servlet using StringTemplate:

(ST)page.render();

When I do this, StringTemplate prints warnings to Stderr; filling up log files with useless warnings is not ideal.

If I understand the documentation correctly, will the following fix this:

STWriter out = new MyCustomWriter(response.getWriter());
page.write((STWriter)out, (STErrorListener)myListener);

And on a side note, will doing this save having to build an entire page of strings in memory?

Have you tried modifying your templates to correct the warnings? — Sam Harwell, Feb 26 '14 at 02:31
@280Z28, Its a warning that I cant get rid of. (At least not anyway I can see) — Jay, Feb 26 '14 at 02:43

I've put some time into digging through the javadoc and mucking around with the code, the following seems to suppress the errors completely:

page.write(new NoIndentWriter(response.getWriter()), new ErrorBuffer());

The ErrorBuffer simply collects all the warnings, which I can then ignore, or process if need be.

(I should post a separate question about if its possible to prevent this warning, but for now this works)

that is the correct solution. We generate errors and you are free to ignore or report the ones you want. – Terence Parr Mar 03 '14 at 18:02
