Smaran,
crud.xpl is the implementation of the persistence services,
i.e.:
/fr/service/oracle/crud/…
This URL is not the same as the URL that you see in your
browser. It is the URL of an HTTP service, called either from XPL, or from
XForms, as explained in another message.
If you want to pass parameters to an HTTP service, you have
a few options:
* use the request body; this is not possible here because
the body contains the form definition of data
* use request parameters; this should be possible here
* use HTTP headers; this should also be possible here
There are 2 sides to this:
* crud.xpl extracting the request parameters/headers from
the request, using oxf:request
* whoever calls the service must pass those request
parameters/headers

Hi
You mean to say I have following url while creating new form http://localhost:8080/orbeon-PE/fr/orbeon/builder/new
so you suggest me to change url as below?
http://localhost:8080/orbeon-PE/fr/orbeon/builder/new?username=smaran
so that I can acess in crud.xpl as
<username><xsl:value-of select="$request/ username
"/></username>
Please correct me if I am wrong attaching my crud.xpl for reference
Regards,
Smaran

Smaran,
There are two ways that I can think of to add attributes to that XML infoset;
changing the HTTP request that the request generator is describing and
transforming the infoset using XSLT. I think the first way is the one you might
be interested in.
Depending upon how crud.xpl is activated in page-flow, you could add URL
parameters to a GET request and they would appear in the request infoset. So if
your page flow was like this (not tested):
And you made this GET request
http://locahost:8080/orbeon/crud?username=tom&password=insecure
This would appear as part of your request infoset (the rest of the infoset
excluded for brevity):
username
tom
password
insecure
Similarly, if you change any other parts of the HTTP request the crud.xpl
receives, like the port, remote address, or anything else, those values will be
changed in the request infoset.
I recommend you add a debug attribute to your request generator and then
execute crud.xpl with different HTTP requests, whilst watching the output of
orbeon.log to see how the XML changes.
/request
Now if what you're actually trying to achieve is an authentication mechanism, I
have had success by reading session parameters in XPL using the scope-generator
processor. In my application a Struts action handles the authentication against
LDAP and writes a parameter isValid into the session if the authentication is
successful. Any pipelines that need to be authenticated are able to read from
the session and check for that value:
isValid
session
application
Hope that helps,
Tom
