Programatically adding facets to a pre-existing project [message #204480]

Hi,
We need to provide support for upgrading our users projects. We have
projects that are several years old and would like to 'add' facets to them
in our upgrade process. Does anyone have any insight into this?

Much appreciated,
mike

See my post from 11/2/2207 in this group called "new proj wizard". Here
is what you can do to programtically add the facets to make a project a
dynamic web module:

// add the java and web facets
IFacetedProject fp = ProjectFacetsManager.create(proj, true, null);

fp.installProjectFacet(ProjectFacetsManager.getProjectFacet( "jst.java")
.getDefaultVersion(), null, null);

fp.installProjectFacet(ProjectFacetsManager.getProjectFacet( "jst.web")
.getDefaultVersion(), null, null);

Actually after reading the project thread below I think I'm all set.
Looks like ProjectFacetsManager does everything I need to know about.
Thanks,

that thread is very useful! I see that the ProjectFacetsManager api's
will convert the project to a faceted project if necessary. Thanks!

ProjectFacetsManager handles our core usecase of upgrading a facet-less
preject to our new facet beautifully! One issue I'm hitting is that
because we depend on jst.java and jst.web, I need to be able to set the
jst.web Content directory path in some circumstances. By default, it
sets the content dir to 'WebContent', but there are instances were I
need to set that to something different. I am familiar with setting
facet properties via the DataModel, but does that apply when using the
ProjectFacetsManager api's? Sorry if I'm missing something obvious here.

Also, does anybody happen to know if jst.web can have no content
directory set? That is, having WEB-INF at the root of the project,
instead of buried in the content dir?

Thanks again,
bouge

Here is how you can get at the datamodel that you can use to
parameterize the installation of the jst.web facet. I believe you can
set web content path to project root, but I don't recall exactly which
value you have to use. Experiment with either null or an empty string.

IProjectFacetVersion jstWebSomething = ...

IActionDefinition actionDef = jstWebSomething.getActionDefinition(
IFacetedProject.Action.Type.INSTALL );

IDataModel dm = (IDataModel) actionDef.createConfigObject();

Hope this helps,

No such luck with empty string, null, /, ., etc... Any other ideas on
how to set the webfacet to point to the project root for it's contentdir?

Looking at the WebFacetInstallDelegate leads me to beleive that it's
expecting a path name under project.

Thanks again,
