Hi All. This is my first time using Tacos or doing ajax stuff, so if
this is a silly question, please bear with me. I'm trying to do a very
simple thing, have a Tacos AjaxDirectLink send a request to the server
and just update some text in my page with the server's response i.e.:
<a jwcid="@tacos:AjaxDirectLink"
listener="listener:updateMessageWithName"
parameters="ognl:{currentNode.name}"
updateComponents="ognl:{'message'}">some text</a>
Nothing too outlandish, I would think. It doesn't appear that my
request even makes it to the server, however. When I turn on Dojo's
debugging, I'm getting this message:
"DEBUG: ERROR: On line 0 of document : uncaught exception: Permission
denied to call method XMLHttpRequest.open"
This error message is detailed here --
http://www.mozilla.org/projects/security/components/same-origin.html --
but the basic idea is you can't do cross-domain scripting. Now, I'm
just using the tacos AjaxDirectLink component, so I'm not explicitly
attempting to cross-domain script things. I *am* running apache in
front of Tomcat, so maybe that is causing me grief (it says something
about how it has to be the same port number, but all of my URLs look the
same -- no port #s --, I'm just doing URL rewriting via mod_rewrite).
Any ideas about how to go about debugging this? It is completely
stopping any work I might hope to do with Tacos.
TIA,
Danny Mandel
