Note that the last two cover what I call 'JET1', which comes from EMF, and
does not support tag libraries.

JET (aka JET2) does include tags to help with Java generatation. The
typically have a java: prefix:

<java:merge/> lets you use EMF's JMerge facility. Put it at the beginning of
a template, and put in Javadoc comments for @generated classes and class
members. java:merge also works on properties files (although it is much
simpler than JMerge. All it does is add missing property definitions - no
@generated is required or allowed).

<java:importsLocation package="...the current package"/> Defines a location
in the template where calculated imports will be inserted. Use in
conjunction with:

<java:import>fully.qualified.java.class</java:import> - Marks the contained
text as importable. The tag will typically replace the text with the
unqualified name of the class, and an an import statement at
the<java:importsLocation/> tag.

<java:class> - an action, typically used in a main.jet template run a
template and create a java class. Can be nested in <java:package> tags,
and/or <ws:folder> or <ws:project> tags (which would represent the source
folder).

Alexandre:

Regrettably, this is very little more information. I am the only developer
on JET currently. Once the Europa release is out, and I have a bit more
time, I plan to start a JET FAQ, and maybe an article or two.

In the meantime, post your questions to this group. I check it frequently.
