[Yanel-dev] Upgrading servlet spec...

[Michael Wechner]

yes backwards compatibility is a major criteria for Yanel and we need to
find a way to stick to it
as good as possible.

I realize we first have to cleanup Yanel itself regarding the
servlet-api dependency...At the moment the version is
set inside

src/build/dependencies.xml
src/build/pom-webapp.xml

which would actually be sufficient, but it seems that for historical
reasons it is still used inside various "resources", e.g.

src/build/targets/create-new-resource-type/from-scratch-resource-template/src/build/dependencies-with-javax.xml
src/realms/from-scratch-realm-template/res-types/layoutselector/src/build/dependencies.xml
src/realms/from-scratch-realm-template/src/build/dependencies.xml
src/realms/welcome-admin/src/build/dependencies.xml
src/realms/welcome-admin/yanel/resources/show-realms/src/build/dependencies.xml
src/realms/yanel-website/src/build/dependencies.xml
src/resources/atom/src/build/dependencies.xml
src/resources/calendar/src/build/dependencies.xml
src/resources/data-repo-sitetree/src/build/dependencies.xml
src/resources/davcollection/src/build/dependencies.xml
src/resources/image/src/build/dependencies.xml
src/resources/lookup/src/build/dependencies.xml
src/resources/search/src/build/dependencies.xml
src/resources/tinymce/src/build/dependencies.xml
src/resources/xinha/src/build/dependencies.xml
src/test/build.xml
src/realms/from-scratch-realm-template/res-types/layoutselector/src/build/dependencies.xml
src/realms/from-scratch-realm-template/src/build/dependencies.xml
src/realms/welcome-admin/src/build/dependencies.xml
src/realms/welcome-admin/yanel/resources/show-realms/src/build/dependencies.xml
src/realms/yanel-website/src/build/dependencies.xml
src/resources/atom/src/build/dependencies.xml
src/resources/calendar/src/build/dependencies.xml
src/resources/data-repo-sitetree/src/build/dependencies.xml
src/resources/davcollection/src/build/dependencies.xml
src/resources/image/src/build/dependencies.xml
src/resources/lookup/src/build/dependencies.xml
src/resources/search/src/build/dependencies.xml
src/resources/tinymce/src/build/dependencies.xml
src/resources/xinha/src/build/dependencies.xml
src/test/build.xml

so we will first cleanup this and then continue to consider how to best
proceed.

Thanks

Michael
