Javascript IView on portal 7.1

Hello,

In our portal, we have certain functionality that requires calling custom javascript functions from Web Dynpro.

In portal 7.0, we created an ivew from a jsp project, that contained the javascript code and communicated with web dynpro using epcm.

Now we are looking to implement the same in CE 7.1.

What options are there for such functionality?

Thanks in advance, Gershon.
