Apache Velocity IfNotNull

Question

This link describes how to use if not null condition in velocity.

userdirective = org.apache.velocity.tools.generic.directive.Ifnull
userdirective = org.apache.velocity.tools.generic.directive.Ifnotnull

But looking inside velocity tools jar there is no such class org.apache.velocity.tools.generic.directive.Ifnotnull .

What am I missing here?

Answer 1

From your link:

Use a custom directive. cf. IfNullDirective, IfNotNullDirective

You have to put the linked code ( http://wiki.apache.org/velocity/IfNullDirective and http://wiki.apache.org/velocity/IfNotNullDirective ) in your sources, it's not provided in the regular velocity jar.
