Where is gwt log

Logging module and set-property enables logging and set log level. By default PopupHandler , pops up a window to show logs and it has to be disabled as we are using HasWidgetLogHandler. Add a log statement in onModuleLoad method in Fins. Now, in addition to Home tab, content area has a tab to show log messages. With basic content area in place, we move on to design menu bar in the next chapter.

Logger ; import com. The buttons in that section will trigger logging calls on the server, as well as logging calls in SharedClass. Note the slight differences in formatting between client-side and server-side logging, as well as the different handlers each is logged to in the tutorial, server-side logging will simply log to stderr, while client-side logging will log to all of the Handlers discussed above.

In order for events that are logged by client-side code to be stored on the server side, you need to use a RemoteLogHandler. This handler will send log messages to the server, where they will be logged using the server-side logging mechanism.

This logger is disabled by default, but you can enable it in the. When logging is disabled, the compiler will used Deferred Binding to substitute Null implementations for the Logger and Level classes. Since these implementations just return Null, and do nothing, they will generally get trimmed by the GWT compiler which does a pretty good job of removing useless code.

However, it is not guaranteed that other code you write related to logging will compile out. If you want to guarantee that some chunk of code is removed when logging is disabled, you can use the LogConfiguration. Code that normally compiles out will still be present in Development mode. You can use the same condition as above to hide code from Development Mode, as shown here:. The GWT logging framework does not emulate all parts of java.

Logging This document is for developers interested in logging client-side code in their GWT applications. In your.
