BE THE CODER > Template Engines > Freemarker Examples

FreeMarker is a java based template engine for complex template processing. This requires the library freemarker-2.3.16.jar to be in classpath. The following example shows using LOOPVAR_index and LOOPVAR_has_next special loop variables. The first one is a loop count index and other is a boolean specifying whether the current item is last in the sequence or not.
