This is a small and simple but very helpful tool I developed to visualize WLS logs.
The motivation to write it came with the need to filter WLS logs by columns: it really helps to analyze logs by filtering out what is not relevant and concentrating in what is related to your problem.
It is a WIP, and currently it can only parse WLS logs (not stdouts) that use line start tag as "####".
You can filter by any of the predefined 12 columns: Time Stamp, Severity, Subsystem, Machine, Server, Thread ID, User ID, Transaction ID, Diagnostic Context, Raw Time, Message ID and Message Text.
You can also re-order the columns and resize them. There's a button to conveniently copy the contents of the selected line (only the message) to the clipboard.
Give it a try and let me know what you think. Download the jar at the end of this post and start it with java -jar WLSLogViewerApp.jar.

Very useful application, to quick sorting what you need to isolate, to for example, follow a log trace of events.
