For those of you who can't access CVS because of firewall issues and would like to \
retrieve Chainsaw V2, there is an ant script in the 'installation' section of the \
Chainsaw page which provides a CVSgrab task, which can access files from CVS by \
pulling them from ViewCVS.

Thanks Scott - unfortunately I haven't managed to work out how to access cvs from \
behind the firewall yet so I'll have to wait for the jars.
About the jvm heap size (because making the read from a file use a cyclic buffer is \
good, but I think many would agree that a 64m maximum heap size is low by today's \
standards) - am I right in assuming that webstart is only being used while chainsaw \
is in beta, and a "proper" distribution will be available further down the line? I've \
tried to take the jars from the JAVACACHE and run them outside webstart, so I can set \
my own heap size, but haven't had any success so far.
Look forward to seeing my name in the release notes :)
Cheers,
Stephen

Hi Stephen,
I've corrected both the cyclic buffer issue and the no-exception rendering bug. The \
CVS tip is updated and will be reflected in the web start download when Paul has a \
chance to update the signed jars. (Paul, if you're reading this, would you mind \
updating?)
I've given you attribution in the release notes -
Thanks for finding the issues,
Scott

Something else I noticed is that the "cyclic" event list doesn't seem to apply when \
loading in events from a file, as I get an outOfMemory when loading in a file with \
lots of events. Is there an easy way to increase the heap size when launching using \
webstart, or is that something that has to be done in the jnlp file?

Thanks for all the emails... amazing response, I sent the email when I went to bed \
and when I got up there was the solution waiting for me :) I tried loading a log file \
without the declaration, doctype etc and it works! Very pleased...
There are a couple of issues that I have noticed though:
1. If displaying of the Throwable column is enabled, I get an exception when I \
scroll the event list panel far enough to the right that the Throwable column is \
visible... but only for events loaded from a file (not if using the \
SocketHubAppender). I can hide the column and the Throwable is displayed correctly \
in the detail below. Stack trace (this is repeatable if you load in the example file \
in the email below & scroll right):
java.lang.ArrayIndexOutOfBoundsException: 0

2. Location information isn't stored in the XML file, so when I save, quit and \
reload some events I don't get my Class, Method, Line and File fields populated. Is \
this something that's unavailable in the XMLLayout completely, or just because \
Chainsaw isn't using it (yet?!)?
Thanks again for your help so far!
Cheers,
Stephen

After further testing, I found problems with the way I was parsing the XML document, \
and had to revert the changes I previously mentioned.
For now, Chainsaw V2 can only load XML files which are a collection of log4j:event \
nodes - no XML declaration, doctype or eventSet root node. It should be easy to add \
support for complete documents, but ran out of time for now.
Here is an example of an xml file that can be loaded by Chainsaw V2. Hope this \
helps.

Subject: problem loading xml events to chainsaw
Hi,
Been using chainsaw v2 for a couple of days - can't get enough of it, I've introduced \
the rest of the team to it and we're tidying up the logging in our application to get \
the most benefit possible, but I'm having a problem loading xml events from a file \
into chainsaw...
When I try this file, for example (CTRL-O, find file in browse dialog, click OK):
<?xml version="1.0" ?>
<!DOCTYPE log4j:eventSet SYSTEM "log4j.dtd">
<log4j:eventSet xmlns:log4j="http://jakarta.apache.org/log4j/" debug="true">
<log4j:event logger="org.apache.struts.util.RequestUtils" timestamp="1085076287450" \
sequenceNumber="0" level="DEBUG" thread="ExecuteThread: '9' for queue: \
'weblogic.kernel.Default'"> <log4j:message><![CDATA[Get module name for path \
/AdhocEnquiry.do]]></log4j:message> <log4j:properties>
<log4j:data name="log4j.remoteSourceInfo" value="longmdappd17.uk.db.com:4500"/>
<log4j:data name="log4jid" value="1"/>
</log4j:properties>
</log4j:event>
</log4j:eventSet>
I get the following in the webstart console:
piblicID: [null]
systemId: [dummy://log4j.dtd]
log4j:ERROR Parsing error on line 1 and column -1
log4j:ERROR XML declaration may only begin entities.
org.xml.sax.SAXParseException: XML declaration may only begin entities.

There are *definitely not* any blank lines/spaces/etc before the <?xml...
Can anyone help? Although the SocketHubAppender is working really well for live \
monitoring, we need to be able to load an existing XMLLayout log file into chainsaw \
too.
Thanks in advance,
Stephen.
