Newbie help - using OPS from JSP

Hello all

I'm trying to use OPS from a struts application. My intention is to apply to 2 xforms, not to the entire application. I've seen that OPS could be used from JSP but could not find the examples. My application actually is using a JScript based XForm implementation, sends and receive XML. however I found OPS really advanced about the controls and implementation of the standard. The tutorial that explains the way of using OPS from JSP is deprecated? Anybody can send examples about this issue?

If OPS could be used from JSP, is there some feature that I will lost?

Thanks a lot in advance
Emiliano.

Emiliano,

If you want to write your XHTML + XForms page with JSP + Struts, you can
use the OPS oxf:servlet-filter-generator to hook-up the XForms
processor. There is some preliminary doc here that you may want to look at:

   http://www.orbeon.com/ops/doc/integration-xforms-jsp

As you said, I don't think there is a perfect example around, unfortunately.

You may lose performance by doing so, because every time a page is
loaded the XHTML will be parsed and the XForms engine cannot do any
caching based on JSP output. But other than that, it is all right to use
JSP to produce XForms.

The ideal way, performance-wise, it to have static XHTML+XForms pages.

Thanks a lot for your answer, I could see the examples using the nightly build, and are working ok ;). Sorry by the question, but if I wish to integrate into my application only this functionality from Orbeon (processig XForms and sending the XML instance, completed by the user to my application)

1. I should add the filter in my web.xml.
2. I should move the appropiate lib/raries to my own lib directory. Which libraries? Perhaps it's easy to define which not (for instance existxx, hsqlxx, jfreechart, pdfbox, and so on).

after that...Should simply work?
Regards and thanks again
Emiliano.

See the attached ivy.xml, which is a subset of something we built for
a customer. It should list a fairly minimal list of required
JARs. Note that we are not using Ivy to build OPS, but from that file
you can infer the JARs you should copy over.

I wouldn't commit to that ;-)
