I find the official documentation on remote logging wasn’t complete. Here are my notes based on various web sites I visited (here, here, and here). Hope this helps!
You should add the inherits statement below. You should be able to adjust the log level to any of the following: ALL, FINEST, FINER, FINE, CONFIG, INFO, WARNING, SEVERE. I find the popup log console in the browser annoying, so I disabled it.
I had to use absolute URLs instead of relative paths for CSS href attributes. Although this library can potentially help me to eliminate the need to create a separate print friendly display code, this created several challenges:
CSS link difference: After attempted to print using several browsers, I discovered that different browsers will interpret href attribute for the CSS links differently. To avoid the need to create browser specific code, I tried the following workaround:
Element body = RootPanel.getBodyElement();
This will print the whole page, which includes all the CSS references that are already working for the browsers and eliminate the need to define separate CSS links that does not work across browsers. :)
Image link difference: I also discovered that the image links are also broken when attempt to print. This is a known “feature” according to gwt-print-it documentation. So, instead of defining images using <img> tags, I used background-image definition in my CSS file and use a div tag with an ID to associate with the CSS definition. See answer #7 in this page for code example. This effectively unified how browsers reference images, which always relative from where CSS file is located. This means I no longer need to create print specific URLs for images. :)
Background image printing: Once I started to use background images, Chrome stopped printing the images. A search on Internet led me to this solution, which worked great. :) For Mozilla, users can enable printing of background images by select Options tab in the Print window and check “Print Background Images”.
Here are some information that I found on the net about JavaOne 2010. Feel free to comment with additional resources. To start, Oracle posted some video highlights. If you have JavaOne login, you can view the full versions at On Demand site. If not, you can still see some of the contents here. Beyond that, here are posts from various speakers on their talks and related links.
I spent a little bit of time check out both webtest and jWebUnit. Here are my first impression:
