[exoplatform] problem with portlet deployment

["jeremie.garcia" <jeremie.garcia@xxxxxxxxxxx>]

hello community

I'am currently familiarizing with JSR 168 concepts, development and 
deployment

I developped a very simple portlet implementing the doview method to 
display the date.

when deploying it, I can find it in the portlet registry so the 
deployment seems to be ok,
but then, when I set the portlet in for example the home container,  
instead of the date I 've an error msg: "SimplePortlet has error"

I also tryied to deploy the open sources portlets from 
http://portlet-opensrc.sourceforge.net/resources.htm (GooglePortlet or 
RssPortlet)
And I obtain the same kind of messages.

I attached my war file to this mail so that you can have an idea of what 
I've done.

does someone already encountered this kind of problem or have an idea of 
what I should do?

thanks a lot
