How to write to Windows Event Log

Posted on 2003-11-16

I write server-side applications in Java. These are frequently deployed on MS Windows servers. I'd like to be able to write errors to the MS Windows Event Log.

I have seen some code covering this through JNI, but it is pretty horrible. Has anyone any reasonable simple code - or a package - that does this?

(I have looked at
http://www.javaworld.com/javaworld/jw-09-2001/jw-0928-ntmessages.html? 
but it's fairly old and not very nice. I'm hoping for a better way. Is there an ActiveX I could call with Jawin, maybe?).

regards
Simon in Sydney, where the weather isn't as nice as it should be by now)

that solution looks about as good as you'll get.
(Calling an ActiveX component with Jawin is a lot messier in my opinion)

> where the weather isn't as nice as it should be by now

And its just started raining again :(
But as long as it's fine on the weekend for the wallabies I'm happy :-)

Sometimes - actually pretty often - I feel people go a long way out of their way to make things hard. (Actually, listening to my co-worker battling to get IIS/BizTalk, Certicates, Web Services to function together, I think these same people may be spending ALL of their time making things hard).

Ok. I'll try the suggested stuff.
Yuk. JNDI.

Actually I find base Jawin excellent. But the resouce stuff makes it a bit tricky.

Not too worried about the Wallabies - hey, I think I'll go sailing and have the Sydney Harbour to myself!

JNI actually. But all the works already done in the article so there's really not much left to be done. So you don't need to actually write any JNI yourself.

> Actually I find base Jawin excellent.

Yes jawin is nice, but it is just a JNI DLL providing a generic Java interface to Windows DLL. Whereas the code in the article provides a more focussed DLL for performing the task you require.

JNI, JNDI, let's call the whole thing off.

Currently battling to get it to work. It's resisting ...! It looks as though the C stuff has worked - but the Java side is resisting, dammit ... I've only been coding for 30 years, one day I'll get it right ... or maybe I should stick to sailing.

Java doesn't want to run the class. It's usually some dopey problem with the classpath when this happens. But as I don't have one how can it be ... ah, got it. Needed a classpath of "."

Silly program ...


Ok I seem to have an output into the Event Viewer.

Hooray! About time too.

Great. Thanks for the encouragement - want to come sailing?
