There have been a number of Eclipse related announcements this year at JavaOne. I thought it might be useful to do a summary; so in no particular order:

1. Borland lays out their JBuilder roadmap.
2. Sybase announces next version of their Workspace product.
3. Nokia announces new mobility initiatives based on Eclipse
4. Terracotta’s tools are based on Eclipse.
5. Oracle’s participation and leadership in Eclipse projects
6. JackBe’s developer tools support for Eclipse
7. BEA announcing new beta of the Weblogic server and Eclipse based tools
8. Backbase announced tight integration with Eclipse
9. Ericsson announce new developer tools for IMS applications
10. Vidiom announced Eclipse based tools for set-top box development
11. Google announces GWT
    

I apologize if I have missed any announcements, please feel free to add a comment.
