Re: [wtp-dev] a new WTP Architecture Overview document is available
|
David;
This is great improvment over ttrying to understand component
relationships from feature/plugin.xmls and .map files :-)
A few more words on JDT and WST dependencies:
- Conceptually it seems that there should not be any JDT dependencies in
WST, due to our obviosly categoric seperation of Web and J2EE standard
tools. Examples why this is so are abundant ( i.e. xml, php, etc.
tooling does not want JDT is a prereq)
However, the distinction is not clear for Web Services; it is hard to
imagine that proper tooling and frameworks for web services can overlook
java bindings for web services and java types on top of validation, and
delegating Java part of Web Services completely to the JST project would
be a more critical design flaw than a dependency on JDT (i.e. if you need
full WS support your depencey will be JST (an indirectly JDT). So,
I will still be in support of JDT dependency in WST until there is good
reason to state that we can have WS support in WST without
JDT.

I've started a new WTP
Architecture Overview document, temporarily available in CVS as indicated
below.
(After some initial "sanity check" review, I'll move to
website location, and delete old one based on initial contribution).
http://dev.eclipse.org/viewcvs/indexwebtools.cgi/%7Echeckout%7E/wtp-jst-home/WTPArchAndDesignDocs/WebContent/arch_and_design/ComponentsBySubsystem.html
It's basically the "component view" from the previous document. (This one, though, is truly architectural, it describes
where we want to end up ... it does not describe the existing structure, which needs much refactoring and holes filled in).
In this version, I have done much more to group some components into "subsystems".
I think these subsystems will be important for the following reasons:
1. it gives some conceptual simplification, not to be under estimated (we have 11 subsystems, 23 components, and
still too many individual plugins to be easily understood).
2. I think its easier to describe dependancies at a sub-system level, instead of component by component.
3. Most important, for most readers, will be that I think the subsystems can form the building blocks
of our top-most "PDE features" ... some of which would be available via update manager. In fact,
in that overview, I've proposed 3 subsystems be made available via update manager, in addition to JST and
WST, that is. Namely, XML Subsystem (which includes schema and dtd components), JSP Web Resources (JSP editing/model, with all
dependancies, e.g. HTML, CSS, _javascript_), and lastly, the "Database Subsystem" (RDB and SQL).
I picked these three because these are the only three I've heard from both users and other projects as being
important to be available separately from WST and JST.
I'm sure other projects and some users will want more fine-grained pieces ... but I propose that if they do, they would
have to download larger piece and then pick out what they want. (There's always limits and trade-offs
to be made with the divisions ... I've tried to reach a meaningful, but manageable balance). Again, this is a proposal,
please let me know if I've overlooked other requirements or have been too accommodating. In summary, this would be
5 updated manager features, each with "runtime" and "SDK" flavors, for 10 total ... I hope no one wants more!]
[BTW, I also propose we not worry about any accurate sub-feature definition
for WTP M2 ... that we wait until the WTP M3 cycle to even begin defining those in the repository].
Please review overview for accuracy and completeness. I am due to present/review this to EMO
Architecture Council on 12/2, so ... sorry I haven't allowed more time for review.
Ideas and feedback more than welcome, as always.
