I am currently working with webservices. Bruce Scharlau has a nice picture of a graph how the various elements in a .wsdl file are linked together. This picture is generated by a plugin contributed by IBM. The eclipse page also has a download link to it.
Now I am downloading this 55MB zip file, then some EMF stuff and and and.. Sometimes data is flowing in at incredible speeds ro 3kBytes/sec (over DSL!). Then some parts of the download are missing and the update has to start again .. In the end, this sort of action takes ages *sigh*
I really like Eclipse, but this is nightmarish.
And the worst: the feature to generate the diagram is not even available due to some error or incompatibility or missing whatever.
