[Trinidad] Nullpointer from Google Bot
Hi List,
since our application went live, we get some nullpointer during night. Some research has shown that the IP that is accessing the site is known as some "Google Bot" scanning links, ect.
Don't know why the nullpointer happens, looks like the Google Bot sends some "strange" MacOS header in the request.
Can someone have a look at this? It's not critical because it's no real user, but it's not nice to get a nullpointer every night.
Greetings
Markus

AW: [Trinidad] Nullpointer from Google Bot
Posted by Döring Markus <Ma...@tcc-products.de>.
Should work if the Agent is not null.

Betreff: Re: [Trinidad] Nullpointer from Google Bot
Looks like it should be :
private Icon _getIcon(RenderingContext arc)
{
return (Agent.PLATFORM_MACOS.equals(arc.getAgent().getPlatformName())) ?
_macOSIcon :
_icon;
}
This way an NPE can never be thrown. Basically the constant should be
compared to a variable in case the variable is null, where the
constant is never null.

Re: [Trinidad] Nullpointer from Google Bot
Posted by Andrew Robinson <an...@gmail.com>.
Looks like it should be :
private Icon _getIcon(RenderingContext arc)
{
return (Agent.PLATFORM_MACOS.equals(arc.getAgent().getPlatformName())) ?
_macOSIcon :
_icon;
}
This way an NPE can never be thrown. Basically the constant should be
compared to a variable in case the variable is null, where the
constant is never null.

Re: [Trinidad] Nullpointer from Google Bot
Posted by Matthias Wessendorf <ma...@apache.org>.
This is the method in question:
private Icon _getIcon(RenderingContext arc)
{
return (arc.getAgent().getPlatformName().equals(
Agent.PLATFORM_MACOS)) ?
_macOSIcon :
_icon;
}
Will take a look after I am back from vacation :-)

Betreff: Re: [Trinidad] Nullpointer from Google Bot
Hi Markus,
there is already a issue to support other agents, like the KDE-browser
(forgot the name).
I think that this is a related issue.
Can you enter your problem to jira and link to this?
I am not 100% sure but it might be a similar issue (yes, I know the
stack is different).

Re: [Trinidad] Nullpointer from Google Bot
Posted by Matthias Wessendorf <ma...@apache.org>.
Hi Markus,
there is already a issue to support other agents, like the KDE-browser
(forgot the name).
I think that this is a related issue.
Can you enter your problem to jira and link to this?
I am not 100% sure but it might be a similar issue (yes, I know the
stack is different).
https://issues.apache.org/jira/browse/TRINIDAD-1109

AW: [Trinidad] Nullpointer from Google Bot
Posted by Döring Markus <Ma...@tcc-products.de>.
The exception filter is doing nothing more than catching every exception and redirecting to another view.
And the exception filter is just at one point in the stack trace, the NullPointer happens at
org.apache.myfaces.trinidadinternal.renderkit.core.skin.MacOSSwitcherIcon._getIcon(MacOSSwitcherIcon.java:104)
so it's not my code causing the problem.
Btw. we're using
Myfaces 1.1.5
Facelets 1.1.13
Trindidad 1.0.7
on
JBoss 4.2.2
Just to have it all: the exception filter:
private final static Log log = LogFactory.getLog(ExceptionFilter.class);
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
try {
chain.doFilter(request, response);
} catch (Throwable thr) {
log.error("Error occured in jsf request processing: " + thr.getMessage(), thr);
httpResponse.reset();
httpResponse.sendRedirect(httpRequest.getContextPath()+"/faces/error.xhtml");
}
}

Betreff: Re: [Trinidad] Nullpointer from Google Bot
Every NullPointerException is caused by a missing initialization.
My first guess is an initialization error in de.tccproducts.dps.web.utils.lifecycle.ExceptionFilter.doFilter <http://web.utils.lifecycle.ExceptionFilter.doFilter>

Hi List,
since our application went live, we get some nullpointer during night. Some research has shown that the IP that is accessing the site is known as some "Google Bot" scanning links, ect.
Don't know why the nullpointer happens, looks like the Google Bot sends some "strange" MacOS header in the request.
Can someone have a look at this? It's not critical because it's no real user, but it's not nice to get a nullpointer every night.
Greetings

Re: [Trinidad] Nullpointer from Google Bot
Posted by Burghard Britzke <bu...@charmides.in-berlin.de>.

My first guess is an initialization error in de.tccproducts.dps.web.utils.lifecycle.ExceptionFilter.doFilter
