Hi,
I have spent some time investigating which Export-Package and Import-Package
headers are required to run GWT web applications on Servicemix, for which I
have adapted some sample projects from the GWT main distribution to run on
servicemix/karaf.
Please note first that the real GWT jar that it is needed on the server side is
gwt-servlet (http://search.maven.org/#search%7Cga%7C1%7Ca%3A%22gwt-servlet%22).
The samples I've adapted use a gwt-servlet jar patched by me with the following
BND Tool configurations:
{code}
Export-Package: com.google.gwt.user.client.rpc.*;version=2.6.0.rc1,
org.hibernate.validator.engine;version=2.6.0.rc1,
com.google.web.bindery.requestfactory.vm.impl.*;version=2.6.0.rc1,
!javax.validation, !org.hibernate.validator.*, !*.client.*, !*.impl.*,
*;version=2.6.0.rc1
Import-Package: javax.servlet.*, javax.validation;resolution:=optional,
org.json;resolution:=optional, javax.validation.*;resolution:=optional,
org.json.*;resolution:=optional, !com.google.gwt.*, *;resolution:=optional
{code}
I recognize the result is not simple and clean, I strived to keep the imports
as simple as possible, but this is the minimal set I've found to make the
examples working. The alternative would be to make heavy use of optional
imports.
The main issue is that bnd tool get confused by java imports for GWT client
java code (code that does not get executed into the server, but it get compiled
to javascript) that are left on gwt-servlet.jar but the imported classes aren't
there and for the good reason of not being used at all.
As soon as this ticket is addressed, I'll update the adapted samples (you can
find them here: https://github.com/cristcost/gwt-karaf-examples) to use this
bundle and I'll test them.
