INCREDIBLE - NTEventLogAppender.setSource DOESN'T work!!

[ProgDario]

HI,

I'm using the class NTEventLogAppender in log4j distribution.

My code is simple:

NTEventLogAppender eventLogAppender = new NTEventLogAppender();
eventLogAppender.setSource("ASDF"); // <-- I CHANGE THE SOURCE
eventLogAppender.setLayout(new PatternLayout("%m"));

But when I log into NT system, the source in the event viewer is
'log4j' instead of 'ASDF'.

If I use the constructor NTEventLogAppender("ASDF", layout), the source
becomes 'ASDF', but if I call the setSource method, the source DONESN'T
CHANGE!!

Any idea??

Thanks

log4j is open source, why don't you figure it out?
My money is on user error.

Groan.
Recompile your .class file with the new source.

I had a look at the NTEventLogAppender source. Here is the constructor
NTEventLogAppender(String, String, Layout) which all other constructors
call:

public NTEventLogAppender(String server, String source, Layout layout)
{
if (source == null) {
source = "Log4j";
}
if (layout == null) {
this.layout = new TTCCLayout();
} else {
this.layout = layout;
}

try {
_handle = registerEventSource(server, source);
} catch (Exception e) {
e.printStackTrace();
_handle = 0;
}
}

Here is the method setSource(String):

public
void setSource(String source) {
this.source = source.trim();
}

Notice that it does NOT call registerEventSource(server, source),
whatever that does.

However, looking at the method activateOptions() we find:

public
void activateOptions() {
if (source != null) {
try {
_handle = registerEventSource(server, source);
} catch (Exception e) {
LogLog.error("Could not register event source.", e);
_handle = 0;
}
}
}

So maybe you'll have to call that after calling setSource(). Just a
guess, I don't have a Windows NT machine to test it on, and I don't
intend to get one.

THANKS Joona!!

You were right, I solved the problem!!

I also looked at the source but with no enough attention............


Thanks again
