Hi,
I'm working in an environment with mixed a toolset, but all
eclipse-based : some are using WSAD 5, some MyEclipse and others
(including myself) eclipse+WTP.
First of all, big congrats to the WTP-team. I've been using it for a
couple of months now, and it's been a joy. Very intuitive and reliable.
Now, as so many other Java shops, we're doing some Java/web development
based on an extended Struts fwk.
For this work, I'd like to develop/use my own web project creation
wizard. I basically need the existing J2EE web project wizard with some
extras: some extra wizard properties and then copying in some extra
files in the resulting blank web project.
Questions:
- I would like to just write some extensions on the existing WTP
wizard(s), but there seem to be no extension points provided. Are these
planned or possible?
- If no extension points are possible, I'd start off with writing some
extensions on a copy of the org.eclipse.jst.servlet.ui plugin. If so,
what is the risk that one of the dependencies-plugins changes APIs
dramatically in the near future, and my wizard will break?
(there are lots of dependencies on internal classes in other WTP plug-ins)
- Last but not least, if there's someone who has some insight in the
interoperability of WTP plugins with other eclipse-based environments:
what are the chances that I can get something working as well in WSAD
and in MyEclipse?
Many thanks for any info on this!
Erwin

Hi erwin,
The WTP Wizard Framework will be released as experimental API in the M3
milestone, this work is underway. The actual J2EE wizards were released as
API in M2.
The J2EE wizards all extend the "ExtendableWizard" class, and so they
support adding extra pages. The extension points of interest are:
org.eclipse.wst.common.frameworks.ui.wizardPageGroup (what you need to
implement), and
org.eclipse.wst.common.frameworks.ui.extendableWizard (which is already
defined in org.eclipse.jst.servlet.ui for you ..)
The extendableWizard ID of interest is
"org.eclipse.jst.servlet.ui.WebModuleCreationWizard". You will need this in
the wizardID attribute of the wizardPageGroup.
Some doc on the wizardPageGroup ext pt:
<!ELEMENT wizardPageGroup ((factory))>
<!ATTLIST wizardPageGroup
wizardID CDATA #REQUIRED
allowsExtendedPagesAfter CDATA #IMPLIED
pageGroupInsertionID CDATA #IMPLIED
pageGroupID CDATA #IMPLIED>
a.. wizardID - This must match the id defined in the extendableWizard
element in the extendableWizard extension point
b.. allowsExtendedPagesAfter - true|false [-- I'd go with true]
c.. pageGroupInsertionID - If this page is to immediately after another
page, this must match the pageID of the page to insert after.
d.. pageGroupID - specify an id for your content
<!ELEMENT factory EMPTY>
<!ATTLIST factory
className CDATA #REQUIRED>
a.. className - This class is an instance of
org.eclipse.wst.common.frameworks.ui.WizardExtensionFactory
so something like:
<extension point="org.eclipse.wst.common.frameworks.ui.wizardPageGroup ">
<wizardPageGroup
wizardID="org.eclipse.jst.servlet.ui.WebModuleCreationWizard "
allowsExtendedPagesAfter="true"
pageGroupID="com.acme.mycustompages"
>
<factory className="com.acme.MyWizardExtensionFactory" />
</wizardPageGroup>
</extension>
The documentation for this extension point is still lacking, but I've opened
up a defect to track this:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=86192
We are currently working on producing better documentation on these kinds of
things, so if you hit any snags that aren't intuitive or straightforward
feel free to post to this newsgroup or even open defects (within reason) for
better documentation.
I'm not familiar with the details of the MyEclipse environment, but I
suspect that (although potentially bulky) it would be possible to create a
plugin stack from WTP that would allow you to have WTP capabilities side by
side with the My Eclipse functionality. On that note, since you're already
customizing your development environment, you could extend it to use
activities (or "capabilities") to filter out the pieces of functionality
from each of these two products to the best of breed features that you want
to use. You should be able to find information on capabilities on the
Eclipse site or the web.
As for WSAD, you'll have alot of code duplication, but the packages and
plugins are renamed accordingly, what this means though is that you're
likely to have muliple new wizards for the various J2EE module types. Again,
activities (or "capabilities") may or may not help you here.
Kind Regards,
Michael D. Elder

The ExtendableWizard class is in the common component of WST sub project
and J2EE component in JST sub project prereqs common component in WST
sub project.
