logInterceptor() exception after ejbActivate()

[morenito9000]

Hi all,
I've problem when a previously passivated Session Bean
is activated from JBoss.
JBoss container configuration for SFSB is:

<remover-period>5400</remover-period>
<max-bean-life>5400</max-bean-life>
<overager-period>900</overager-period>
<max-bean-age>1800</max-bean-age>
<resizer-period>400</resizer-period>
<max-cache-miss-period>60</max-cache-miss-period>
<min-cache-miss-period>1</min-cache-miss-period>

I call a Session Bean, I don't use it for half an hour and I see
that the bean is correctly passivated.
When I reuse the bean the ejbActivate() method is called
but when I try to call one of bean's method, I have the following error:

2006-03-28 11:15:51,250 ERROR [org.jboss.ejb.plugins.LogInterceptor] RuntimeException: java.lang.NullPointerException

Is there something wrong in container configuration ?
Is there something wrong in my bean's method ?
What is the meaning of this RuntimeException ?

Many thanks in advance for your help

I found the mistake.

There was (obviusly ;-)) a bug in my code.

In ejbPassivate() method I set to null a variable:
InitialContext ic = null;

In ejbActivate() I don't reinitialize this variable so,
when client calls a beanMethod() where ic variable is used,
a RuntimeException is raised.
