Hi,
I have a component in my app that uses SourceResolver to create a
ServletSource. When I call this component from within a pipeline, e.g.
from flow or from a sitemap component all works well. However, when I
call this method from a cron job I get the following NPE:
java.lang.NullPointerException
at
org.apache.cocoon.callstack.environment.CallFrameHelper.getContext(CallFrameHelper.java:75)
at
org.apache.cocoon.servletservice.CallStackHelper.getCurrentServletContext(CallStackHelper.java:112)
at
org.apache.cocoon.servletservice.components.ServletSource.createServletConnection(ServletSource.java:125)
<snip/>
The root problem seems to be that the CallStack is empty and so the the
current ServletContext cannot be obtained using
CallStackHelper.getCurrentServletContext().
Am I doing anything wrong?
IMO no. From a quick glance at the code I think it needs to be more
defensive in terms of catching NPEs. In the case that there is no
existing call frame, null should be returned. Grzegorz, what do you think?
