I installed eclipse on a new unubtu install, via the package manager. I have Galileo. I copied my home directory from an older machine, and tried to open that workspace. Now I dont see any java perspective.
(Possibly, all the info above is not relevant, but I just wanted to add any possible info, as this a clean install of Eclipse via package manager, so I cant think of any other non standard thing I might have done.)
If you do not have a Java perspective even in "Other", you have downloaded one of the Eclipse versions intended for something else than Java. Do it again, but be certain to get the Java or the Java EE version.
Note that Eclipse IS available in the Ubuntu software repository, but it is the version which was current when that version of Ubuntu came out. For the 9.04 I use it is Eclipse 3.4 and I need 3.5, hence I downloaded it myself.
Yes, without perspective you will never be able to see an Eclipse from the viewpoint of Galileo.
You will need to do a "perspective divide". So the perspective radii are:
Thanks to this divide, the moon is almost big enough to block out the entire sun.
So, yes, Perspective is needed to show the Eclipse.
