Yes, one of the controls towards the bottom in the Advanced says "Edit
Source" or "View Source", can't recall the exact name right now, but
it's there.

Also, you won't be able to just take that and run it through the
Orbeon context in your webapp, because it requires quite a bit more.
As of right now, you at least have to use a variety of xsl stylesheets
to transform custom Orbeon components to xhtml, since the source you
see in the formbuilder has a variety of orbeon xform extensions.

Hello,

My background:
I am quite new to Orbeon, Xforms, etc.  However I have been using jsp &
Java for years.  Our company intranet has many custom Java libraries
that I want to make use of.  I have been playing with Orbeon for a few
weeks and have found it excellent.  However, I have to say: the learning
curve is very steep.

I am stuck:
I want to connect to my Java libraries and make use of live lists,
addresses, etc (from ERP, DB, etc).  I have put together a very basic
framework to make sure I can pass data from a custom Java processor to a
webpage.  However I have spent days doing this with no joy (tearing my
hair out etc.)

My request:
Any chance someone could write some very basic code that demonstrates
basic dataflow?  I have been attempting to do it thus:

testProcesor.java
(outputs small test XML doc)

\/    \/    \/

service-get.xpl
(uses oxf:java to access testProcesor.java)
(outputs the returned document)

\/    \/    \/

view.xhtml
(Uses event-"xforms-ready" to call a submission that retrieves data from
Service-get.xpl)
(the output is then displayed on the webpage)


If someone could make a really simple working version of the above three
files (plus page-flow.xml) and send it to me I would appreciate it a
lot.  I am sure I am missing something very simple.  But since all the
components are new to me, I don't know which part isn't working.

Cheers

Steven

Thanks for answer.

But I already saw this "Show-Sourecode-Feature" and this is not what I am searching for.

I want to run this "XForms" after builed in the FormBuilder in the Orbeon Framework, so the extensions should not be the Problem. But I need something like an export funktionality which will generate me at least the following files:

page-flow.xml
view.xhtml
and the xml File the changes, made in this Form, will be saved.

I want to show my local builed XForm in the Forms Designer on an other System. So I planed to generate an folder, put in the Files an upload it to orbeon\WEB-INF\resources\apps.

Hello again,

Contrary to what I was trying to do below, would it make more sense for
me to wrap up my existing Java libraries into web services, then access
these from my Orbeon apps?  Has anyone found this to be a nice simple
solution?  I am aiming to setup an architecture that can be used to
slowly replace all of our existing company intranet.  Currently all of
our internal web applications are written in JSP, access Java libraries,
and are hosted on Apache Tomcat.

Cheers

Steve

What you describe here makes sense. I am wondering what isn't working, and it is hard to tell without seeing your code. Can you hit the service-get.xpl service directly with your web browser, and get the XML back?

If you can, then it must be a problem with the submission. If the submission fails, you will find more information about what went wrong in the orbeon.log. If there is still not enough information there, uncomment the category related to XFormsServer in log4j.xml, and restart Tomcat to get even more information in the logs.

Thanks for that.  I didn't realise I could point the browser directly at
.xpl files(using page-flow).  Once I did I found the error right away.
It now works!

Cheers

Steven

This is also a good way to do it. Especially if you want your code to be accessible as a web service by other "components" (in addition to your XForms forms).

Now, the simplest way is to expose the code you want to call with static methods, and call those methods directly from the XPath running in XForms. For instance, you would on xforms-model-construct-done do an xforms:insert where the "origin" calls a Java method that returns the XML. Also see:

http://www.saxonica.com/documentation/extensibility/functions/staticmethods.html

When you build and app with Form Builder, you don't get an app that gets "generated" for you, and that would put at the level of the other apps. Instead Form Runner works as an "interpreter" for your form; well... it runs your form. Said otherwise: it's not your form using Form Runner, but Form Runner running your form. After you published your form, it will be available from /fr/your-app/your-form/new. Note the "/fr" at the beginning of the URL which denotes that this is going through Form Runner.

Alex

Thanks for confirming that, and the extra info.  Cheers :)
