how to determine the included template file exists or not?
how to determine the included template file exists or not? in my .vm page, i want to write such codes as follows:
#set($var=$param("fileName"))
#parse("${var}.inc")
but sometimes the inc file, e.g "hello.inc", does not exist
so i want to find a way to determine if the included file exists
if yes, parse it, otherwise ignore the #parse directive without any exception
can anyone tell me how to do it?

I think you can create an IncludeEventHandler that returns null when
the template doesn't exists, which would cause the #parse to be
skipped.

but hello.inc maybe is a relative path
and it is difficult for $templateTool to decide

One option is to write a Java class for checking template existence and put
it in Velocity context as a tool.
#if( $templateTool.exists("hello.inc") )
#parse("hello.inc")
#end

One option is to write a Java class for checking template existence and put
it in Velocity context as a tool.
#if( $templateTool.exists("hello.inc") )
#parse("hello.inc")
#end
