erlydtl example taken from the upcoming book:"Building Web Applications with Erlang"

Hi, I setup yaws and erltdtl as follows

 

(foo@plun0142)1> code:add_path("/home/u1c332/test/templates/erlydtl/ebin").

true

 (foo@plun0142)3> code:add_path("/home/u1c332/erlydtl-0.7.0/ebin").

true

(foo@plun0142)4> l(erlydtl).

{module,erlydtl}

(foo@plun0142)5> cd("templates").

/home/u1c332

ok

(foo@plun0142)6> cd("/home/u1c332/test/templates").

/home/u1c332/test/templates

ok

 

(foo@plun0142)9> erlydtl:compile("/home/u1c332/test/templates/hello_world.dtl",hello_world,[{out_dir,"/home/u1c332/test/templates/erlydtl/ebin"}]).

Ok

 The dtl code is  at /home/u1c332/test/templates/ hello_world.dtl  is

 <h1>Hello {{ planet }} </h1>

 The compile produces a beam at:

/home/u1c332/test/templates/erlydtl/ebin/ hello_world.beam

 

I constructed this yaws code in /home/u1c332/test/yaws/www/ hello_world.yaws

<erl>

out(Arg) ->

{ok,HTML} = hello_world:render([{planet, "Earth"}]),

{html, HTML}.

</erl>

 When called at http://plun0142:8001/hello_world.yaws

 It should  output this:

 <h1>Hello Earth </h1>

 But I am getting this instead

Internal error, yaws code crashed

Any help is welcomed.
