Recently I started working with RAD and WebSphere on development of web services and found out that it takes a while to republish ear file once changes are made to the code.
Any tricks and suggestions to speed them up?
There is a known problem about this, see: http://www.ibm.com/support/docview.wss?rs=180&uid=swg21396021
Setting the metadata-complete value to true in your web.xml will prevent scanning for annotations and speed up things.
You can also use the Annotation scanning filter in the manifest file of the module to selectively prevent annotation scanning of jar files.
