Rudolf,
the common way is to use statushandlers. There is a document about this 
on Wiki: http://wiki.eclipse.org/Platform_UI_Error_Handling
It's generally about traveling of statuses. You can get a status (eg. if 
you catch CoreException, then coreException.getStatus) or eventually 
throw your own, in any crisis or success situation.
To handle a status you call StatusManager.getDefault.handle(...);
So it looks easy and is easy. The way, how statuses are handled (error 
dialog, only log, etc.) can either be suggested directly with a style in 
handle(status, style) method or customized by creating your own status 
handler and registering under org.eclipse.ui.statusHandlers extension point.
Status contains a name of originating plugin, message, status code and a 
Throwable if it applies. Statuses can also be grouped eg. if they are 
all related to one issue.
There is also a service at lower lever - in Equinox - 
(org.eclipse.equinox.log) to which you can register to catch up and 
eventually process any errors, but this plugin has to be downloaded 
separately from Equinox.

Of course you can still use log4j in your plugins, and afaik some people 
do this, but it offers something quite different, so I guess which one 
you choose will mainly depend on what you really need.
