[htmltmpl-java] testing for parameter existence

[Costantino, D. <Dan...@gs...>]

Hi,

I want to test for the existence of a parameter in a template.  How can I do
this without generating a java.util.NoSuchElementException?

At present, I simply wrap each getParam(<test_name>) call around a try ...
catch block.  This seems inefficient.  Is this the only way to do it?  I
only trying to determine if the template variable exists in the specific
html template I'm presently reading.  I don't actually need its value.

Thanks
