OK, looks like Groovy has explicit try/catch
(http://groovy.codehaus.org/JN3035-Exceptions). I couldn't see anything about Velocity
catching exceptions (only about Velocity throwing exceptions -
http://velocity.apache.org/engine/devel/developer-guide.html#exceptions).
Yes there is nothing in standard Velocity but XWiki add some tools to
Velocity and among other things some try/catching support, see
http://extensions.xwiki.org/xwiki/bin/view/Extension/Velocity+Module#HVeloc….
What Vincent meant by automatically caught is that you get to see the
error in the error where you have put the {{velocity}} macro, it does
not break the whole page.
and can
this be caught within the Velocity or Groovy code that calls it?
errors are automatically caught in the script macros ({{velocity}}, {{groovy}}, etc).
So if I have a component that I call from velocity with $mycomponent.foo() and the method
throws an exception (IOException, for instance), can I control what the Velocity script
does about this?
