problem loading xml events to chainsaw

[Stephen Pain <st...@db.com>]

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.
