I have added a major feature to log4js-ext, remote logging support, that allows sending log data to your remote web server.
There is built-in support for all major Java logging frameworks: Log4j, Slf4j and Apache Commons Logger. To learn how to use it, visit this link.
Another major addition to log4js-ext 2.0 is a powerful search & highlight feature to log4js-ext log window: now, it is possible for you to filter logs, and then perform fine grained searches for specific values.
If you click the image below, you will see that there is a new search toolbar, and that the logged text is highlighted in several log entries: this is a real time saver when digging into a ton of data.
To make life easier I am hosting the API documentation online.
Log4js-ext is developed using Test Driven Development, to guarantee is is a high quality product. Want proof? Take a look at the test results for version 2.0.
Log4js-ext is Open Source, you can download and start using it now, free of charge.
Enjoy!

Does not seem possible to use just the remote logging “without” using the log window, as log4js-ext-all-dev.js requires RowExpander and StatusBar which are not needed for just remote logging
Just so that others do not misunderstand, you can *use* remote logging without using the log window. I’ll assume what you meant is that log4js-ext-all-dev.js contains all log4js-ext files, not just those you want to use for remote logging.
If you want to hand-pick what to include and what not, get the source files, combine them, and minify the resulting file. Should be easy.
