I could not understand this reasoning, please enlighten me. What is the strong
dependency beteen web services and java? And, if there is such stroing ties,
why putting everything under JST would be a critical design flaw?

I though web services where about the provider and the consumer being any
language you wish to use. I can, for instance, write consumer for web services
using PHP and providers using Perl. I can get great plug-ins for PHP and Perl
development under Eclipse. But why should I need to install JDT in order to
develop my webservices using Eclipse WST if I won't use Java at all?

On the other way, the Web Service support for Java is officially part of the
J2EE and it requires other J2EE components, like web containers. Even the
non-web part of it (like JAXB, XML bindings to Java classes) are defined as
part of the J2EE plataform. So, if I had to use Java to implement web services,
JST would be the natural fit for those Eclipse components.

Maybe the tools you use to develop Web Services were written using Java. Maybe
some of them are focused on Java developers. The first case you can solve by
factoring out the dependencies from the JDT so I don't need to include all of
it to just generate and validate WSDL files, for example. The second case can
be solved by creating a component that I don't need to install on order to use
other web services-related functionality from WST on my non-Java development.

PS: I hope no one gets pissed of me being so vocal on list about my opinions
but not having provided a single patch so far... PHP and Perl developers were
allways glad to receive the feedback of someone who would be using the tools
early on their design cycles, but maybe you prefer to have a more closed
discussion beteen developers.
