Hey Bert.. My bad..

I din’t put the buttons inside a form..
and it wasted 1 week of mine.. just imagine..

and regarding the ” Unable to determine the FaceServlet mapping for servlet path ‘null’ “ error.. thats just a bug and doesn’t affect the performance of the portlet

Thanx loads for this article

I’m presently trying to implement database interaction in the portlet using hibernate and liferay’s ant build-service..

Phew!!

Thanx again

I am sure there must be a difference, did you check if all the files are exactly the same?

Hey Bert,

I followed every step u suggested. Then i modified my portlet to include buttons and accordingly made changes in the faces-config file. But the buttons wont respond. The error on the server console is ” Unable to determine the FaceServlet mapping for servlet path ‘null’ “. I downloaded a sample sun jsf portlet. It works. I am not able to find the difference. Any idea?

Hello Ram,

Thanks for your valuable feedback! The code is misformed by the syntax highlighting plug-in I use for my blog. I will try to fix it as soon as possible. In the meanwhile please look at the files in the download.

Hey,

Though ur post is short and simple, There are many errors in the code u have displayed. the tags are not correctly nested and there are many unnecessary spaces. The code u have put for download is good. Please correct.
Thanks
