Subject Re: Getting started with Chainsaw
Date Mon, 22 Mar 2010 15:31:40 GMT
Whoops. Nice catch!

I fixed those problems and a "pluginDirectory cannot be null, and it
must exist and must be readable, using the normal Classloader" error I
saw in the chainsaw-log tab.  I just created an empty plugins
directory in my ~/.chainsaw dir.

I don't see anymore errors. The warnings I'm getting in the
chainsaw-log file are:

-Could not find any local JavaDocs, you might want to consider running
'ant javadoc'. The release version will be able to access Javadocs
from the Apache website.
-Failed to locate Receiver class:org.apache.log4j.net.JMSReceiver
-Failed to locate Receiver class:org.apache.log4j.db.DBReceiver
-Failed to locate Receiver class:org.apache.log4j.db.CustomSQLDBReceiver
-Failed to locate Receiver class:org.apache.log4j.xml.LogFileXMLReceiver
-Failed to locate Receiver
class:org.apache.log4j.chainsaw.vfs.VFSLogFilePatternReceiver
-menu 'Connect to' was NOT added because the 'Help' menu could not be located

I do see this in as a debug, which is promising:
Located known Receiver class org.apache.log4j.varia.LogFilePatternReceiver

I still don't see the tab for my sample.log popping up.
Anymore ideas?


Here's some console output:
