Hello.
I was trying to follow examples in
http://yarivsblog.com/articles/2006/10/27/introducing-erlyweb-the-erlang-twist-on-web-framworks/
and succeeded partially.
My yaws.conf :
--------------------------------------------------
<server localhost>
port = 10080
listen = 0.0.0.0
docroot = /tmp/music/www
appmods = <"/music", erlyweb>
<opaque>
appname = music
</opaque>
</server>
--------------------------------------------------
When I call http://localhost:10080/music I get:
------------------------------------------------------
ERROR erlang code crashed:
File: appmod:0
Reason: {{badrecord,arg},
[{yaws_arg,opaque,1},
{erlyweb,get_app_name,1},
{erlyweb,out,1},
{yaws_server,deliver_dyn_part,8},
{yaws_server,aloop,3},
{yaws_server,acceptor0,2},
{proc_lib,init_p,5}]}
Req: {http_request,'GET',{abs_path,"/music"},{1,1}}
--------------------------------------------------------
But at the same time I get correct page (Welcome to 'music'...) if I
call simply
http://localhost:10080/
At first I thought I can live with that, but new troubles appeared
with mysql example. I've done all required steps(start mysql
connection, compile) and have component:
3> music_erlyweb_data:components().
{2,
{"musician",
[{delete,2},{edit,2},{new,1},{list,2},{list,1},{index,1}],
{"html_container",[{index,2}],nil,nil},
nil}}
but i can not reach it in any way.
http://localhost:10080/music/musician leads to
ERROR erlang code crashed:
File: appmod:0
Reason: {{badrecord,arg},
[{yaws_arg,opaque,1},
{erlyweb,get_app_name,1},
{erlyweb,out,1},
{yaws_server,deliver_dyn_part,8},
{yaws_server,aloop,3},
{yaws_server,acceptor0,2},
{proc_lib,init_p,5}]}
Req: {http_request,'GET',{abs_path,"/music/musician"},{1,1}}
just http://localhost:10080/musician produces '404 Not Found'.
I'm using Yaws from svn trunk and erlyweb-0.6.2
Any suggestions are appreciated.

Hmm, it's possible Yaws from trunk has a different 'arg' record. Try
building ErlyWeb from source by first modifying the path to Yaws in
erlyweb/Emakefile and then calling 'make' in the erlyweb directory.

Hi, Yariv.
With those steps still http://localhost:10080/ works OK, but i get
following error with
http://localhost:10080/music (before calling /music i also need invoke
erlyweb:compile("/tmp/music"). in yaws's shell as message in browser
indicates):
ERROR erlang code crashed:
File: appmod:0
Reason: {function_clause,[{lists,dropwhile,
[#Fun<erlyweb_util.
3.94515813>,undefined]},
{erlyweb,get_ewc,2},
{erlyweb,get_initial_ewc1,2},
{erlyweb,handle_request,4},
{yaws_server,deliver_dyn_part,8},
{yaws_server,aloop,3},
{yaws_server,acceptor0,2},
{proc_lib,init_p,5}]}
Req: {http_request,'GET',{abs_path,"/music"},{1,1}}
------------------------------------------------------------------------------------
BTW, it would be good to have note somewhere in erlyweb about erlang
version dependency.
In previous post i used R11B-2 from FC7 rpm package (just was faster
to start with). For compiling erlyweb trunk I used latest R11B-5 built
from source.

Ugh. I looks like the Yaws trunk code is quite unstable. I recommend
that you use Yaws 1.68 if possible. It looks like the appmoddata field
in the arg has changed in trunk.
