Howdy,
The attached has always seemed to me almost too trivial, but it's made my
log-reading life vastly more pleasant.
It's an ObjectRenderer for Calendars and Dates. Although Date has a
half-decent #toString() (and the java.sql.Time a quite pleasant one),
Calendar's #toString is something only
Hi Viv,
You aren't specifying an implementation of the SnmpTrapSender interface in
your configuration.
Your config should look like this - the second line is the one you are
missing.

I have released a new version of the SNMPTrapAppender on my Web site

The new version includes the following changes/improvements:

Greetings,

interface which uses the open source NetSNMP command line tools to send
traps. I wrote this primarily as a proof-of-concept several people
Greetings,
There's a new release of the appender on my Web site. This release includes a fix for
the string vs. byte array bug reported by Steve Meyfroidt, and the SysupTimeResolver
idea contributed by Thomas Muller.

Enjoy.
Hi Thomas,
That's purty! :-) I'll add it and list you as author/contributor. I am reluctant to
just kill the #setSysUpTime method/property, for backwards compatibility reasons, but
I did deprecate it, and modify the appender to use the resolver's value whenever the
sysUpTime property is n

I've released a new version of the SNMPTrapAppender. The new version addresses
problems involved with compatibility with Log4J version 1.2.x, as well as attempting
to address a raft of complaints/requests that I've received over the course of the
last year. Here's the blurb I've

First off, please forgive me for copying my answer to you to the list, but this is a
very interesting question, and I can imagine the answer might be helpful for other
folks. Above and beyond that, maybe somebody else is already using the appender with
Tivoli and might be able to

Hi Ceki,
Could you add a link on the Web site somewhere for the SNMPTrapAppender? The URL is:

I occasionally get mail from people who somehow manage to find a reference to this in
the list archives, but not the specific mail that ha
Greetings all,
For those interested, I've put the SNMPTrapAppender up on my Web site, with a brief
description, and a link to download the two classes and their JavaDocs as a Zip file.
The copy on the Web site has a version of the SNMPTrapSenderFacade class with a minor
bug fix - this is n
>>I don't see any attachment included...<<
Eh? Really? The copy of my mail that I got back (from the Log4J user's
list) has all the attachments. It's probably an Outlook weirdness. I'll
look at it tomorrow. If all else fails, I'll post links to my Web site,
where you could pull the files from
Jim,
I've gotten this one recently. I discovered that I had some stuff in my
class path that included older copies of XML parsers (Crimson, for example).
When I cleaned up the class path, so I was sure which parser was loading and
which version, this went away...

It's your call Ceki - I hope you're right! ;-)

Hey, thanks for the tip, Jin. I had flown over the OpenNMS site, but I was
under the impression that they had abandoned this and were just
concentrating on the mgt. server and console. I'll check this out. If I
can, I'll re-visit the SNMPTrapAppender, and post an updated version to the
list.

Ahh! I got it. Sun's download site for the JMX offers two options -

Jars, Javadocs and a whole lot more. That includes the HtmlAdaptor. The

Hi Ceki,
Since I was on a quest to find a way to append to an SNMP trap last week, I
spent some time researching the upcoming JMX API from Sun. I had high hopes
that I would be able to use this to allow me to create an open,
vendor-neutral implementation of an SNMP trap sender. However, my rese

Eddie,
Nobody's probably jumping to answer your more general question because the
NDC mechanism is very flexible - it is impossible to say "this is THE right
way to use it", simply because there are so many different ways that you
could use it, for many different purposes. Having said that, the

a subtle and complicated issue.
Short answer: I think that you would find that setting the priority at the
Category level is faster, in t

community. This is, obviously,

You don't need to jump through this many hoops to get this behavior - there

Listen, I'm hardly a Log4J guru, but this topic is discussing something that

I've got a server process, which services applets via RMI. The server (not

Hey all,
Anybody gotten the DailyRollingfileAppender (from b4) working in a

Any ideas? The above example prompts Log4J to regurgitate "log4j:WARN No

You could write some kind of a simple watchdog process that monitors for
