server sets "initComplete=true" to early
Hi Maxim,
I've seen you've added some code in the ScopeApplicationAdapter when the
server is inited lately.
In the servlets we check for that variable
(ScopeApplicationAdapter.initComplete), in order to make sure the server is
up before we request the bean.
The issue is that you can still provoke a NullPointerException, cause the
option in the ScopeApplicationAdapter is reached before the
ApplicationContext is available.
In the past it was possible to make the server stuck in the boot, it never
really booted when you hit F5 at the right time a number of times.
I think it is still possible to do that if you penetrate the server hard
enough as the "initComplete" is true too early.
Do you have an idea where else in the code we could set the flag
"ScopeApplicationAdapter.initComplete" ? Somewhere later... but I have no
idea currently where.
You will an exception like this:

I just refactor this method to be

Re: server sets "initComplete=true" to early
Posted by "seba.wagner@gmail.com" <se...@gmail.com>.
I have committed another version.
Please review.
Its indeed a little bit tricky cause the Axis2 deployed services do not
allow a method like:
public <T> T
cause it will try to build a webservice for all public methods in that
class, and it cannot make a return type for <T> / Templates.
So I have added this BeanUtil as class reference.
The other servlets have a Base servlet now, to inject their specific
ServletContext.
It is arguable if there is really a need for a Base-class for those cases.
However this is now just the way I did it, feel free to re-structure.
However at least the check:
if (ScopeApplicationAdapter.initComplete)
is only done in one place in the code.

Sure, this is why I have asked who is going to do the refactoring :)

Re: server sets "initComplete=true" to early
Posted by "seba.wagner@gmail.com" <se...@gmail.com>.
Sorry but I will overwrite that.
You've just fixed one Bean getter method. There are around 25 accross our
code base in several Axis-WebServices, HttpServlets and VelocityViewServlets
Please give me some minutes, I will ping you again.
