NPE in PortletInvokerImpl (1.0.1-rc2)

[Nico Max <ni...@db.com>]

Hi all,

I have recently downloaded the latest distributions of pluto (1.0.1 rc-2) 
and tried to get it running.

I've encountered an exception when opening the test portal which already 
have been discussed here. (see the attached stacktrace).

What did make me wonder was that the full bundle works out-of-the-box, but 
when deploying the packed wars from the
tools-distribution, the test fails.

It seems that the root cause of this is that the web.xml of the testsuite 
are different in these distributions. So it seems that the NPE is an 
aftereffect of an invalid configuration in the first place.

What I would like to see is a fixed web.xml in the tools distribution and 
an explicit check with error logging to avoid aftereffects from an invalid 
configuration.

regards
Nico


Here is the stacktrace:
