RE: Problems call OPS from JSTL

Alex,
This won't work for me I'm afraid because we don't have direct
access to our production machines so we can't amend the URL to suit this.

Reading the tomcat configuration documentation
(http://tomcat.apache.org/tomcat-5.5-doc/config/context.html) I noticed the
crossContext property says this:

Set to true if you want calls within this application to
ServletContext.getContext() to successfully return a request dispatcher for
other web applications running on this virtual host. Set to false (the
default) in security conscious environments, to make getContext() always
return null.

I need the crossContext set to true for c:import/@context to function so
maybe to problem lies with the use of the ServletContext object?

Re: Problems call OPS from JSTL

Administrator

Ryan,

The context object is only used on the caller side, that is the JSTL
side. In OPS we get a request, and from the request, we should be able
to get the requested URI with request.getRequestURI(). The problem is
that this call does not return the URI you specify in the c:import,
but the URI requested by your browser.

I am not sure what to make of this, so I asked a question in the
tomcat-users list, and we'll see if I get a useful response.

Re: Problems call OPS from JSTL

Administrator

Hi Ryan,

To follow-up on this: I have posted a question on the tomcat users
mailing list on Jul 12 which didn't get an answer so far. So it looks
like this issue will stay open, as we depend on Tomcat for passing us
the correct request URI, and I don't know what we can do in this case
as it looks like we don't receive the correct request URI from Tomcat.

RE: Problems call OPS from JSTL

Alex,
Thanks for your help on this, I'll try and investigate it a little
more, see if there is a common way to handle this response. What java file
handles the request, in case I need to experiment?

Re: Problems call OPS from JSTL

Administrator

Hi Ryan,

With a debugger, you can put a breakpoint in the 'service' method of
'OPSServlet'. There you can look at what you get a in the 'request'
object, an in particular at what is returned by
request.getRequestURI().

Re: Problems call OPS from JSTL

Hello everybody

Sorry by the question, but I'm trying to understand if actually Orbeon
could be used from JSTL. I've understood wrong or actually is not
working ok?

I'm looking for a way to integrate for an existing Struts application
an XForms implementation. I've tried using Orbeon as a filter but
perhaps from JSTL should be more comfortable, isn't it?

Thanks and regards
Emiliano.

Re: Problems call OPS from JSTL

Hi Emiliano,

It looks like you are doing the right thing: if your application is
using Struts and JSTL, you generate XForms in your JSP files, and
setup PresentationServer as a filter.

If you don't need to use JSP files anymore, we recommend you use
PresentationServer as a servlet and place your XHTML+XForms files in
the resources, which is even better for performance as this will allow
PresentationServer to caching more aggressively your XForms.
