How do I call java methods on an object from a FreeMarker template?
FreeMarker allows invoking methods that were made available through the model from within expressions.
Assuming your object has been exposed as myBean
you can invoke the method as follows:
<#list myBean.getunits("myType") as unit>
do stuff with ${unit}
</#list>
You don't have to use <list>
, of course, it's just there as an example since your method returns a list.
As ChssPly76 said, you can just peform the method call from within a Freemarker template, as long as you expose the object in the model.
But it's important to keep in mind that if your method returns NULL (for whatever reason), you are going to get a confusing
Expression myBean.getunits() is undefined on line ....
To avoid this, you should better use myBean.getunits(...)!
(notice the exclamation point).
