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
