Java and input:instance / url parameters

Hi, now that I have the separate deployment of Orbeon working and my jsps are processed by Orbeon, I realized that accessing doc('input:instance') in my XForms no longer returns anything. I created my forms in the resources directory of Orbeon, using Orbeon, and now I have tried to use them through a JSP and can't get URL parameters. When using page-flow, the parameters have to be defined in page-flow.xml, but with Java, there is no page-flow... how can URL parameters be passed in?

I can think of two ways but they are both terrible: to use request.getParameter() in the boparameter.xhtmldy of the XHTML/JSP; however, my JSP loads XHTML from a database, and then just spits it out, so this wouldn't work. The other solution is ugly; do a string search and replace in the XHTML returned by the database.

I have attached my XHTML file. For testing as a JSP, I simply change the file extension to .jsp.

I hope there is some way my XForms can still access input:instance...

Am I right to assume that you were using something like <setvalue
ref="/submission/first" parameter="first"/> in your page flow to set
some value in the instance, and then accessing this instance in XForms
with "input:instance"? If this is the case, you could now use
xxforms:get-request-parameter() in XForms, or have the instance inline
in the JSP and use JSP tags to insert the request parameters into
elements or attributes of the instance.

Re: Java and input:instance / url parameters

Alex you are correct, I used setvalue in the page-flow file. Inline code won't work easily because the XHTML returned by the database is arbitrary. I tried googling for xxforms:get-request-parameter() and it looks like its only available in 3.7; I am using 3.6. If these are the only options I suppose I will need to do a string search/replace on the XHTML returned by the DB for now.

So the database returns XHTML+XForms which the JSP inserts into the page; right?

Right, xxforms:get-request-parameter() has been added recently and you
would have to upgrade to a nightly build.
