What's the best way to get the tomcat version and the path to the content
directory of JSP projects programmatically? Also, what's the right way to
detect whether a project is a JSP project (do I try to detect the jst.web
facet? how would I do that?). I could read the data directly out of the
XML files, but I'd rather do it with the proper API's to ensure forward
compatability.

For each IRuntime r, you can use:
String typeid = r.getRuntimeType().getId();
to get a string that will end with two digits indicating the version as
32, 40, 41, 50, or 55. I'm not sure if it is technically public API,
but this approach is probably reliable as I don't think the id strings
will be changing. See the plugin.xml file in the
org.eclipse.jst.server.tomcat.core plug-in to see the full id strings.
They are declared at the beginning of this file.
Cheers,
Larry

Thanks Konstantin. I had forgotten about the other IRuntime.
Justin, the strings to expect runtime type id and version for Tomcat are
found in the tomcat.core plugin.xml file under the
"org.eclipse.wst.common.project.facet.core.runtimes" extension point,
i.e. the id will be "org.eclipse.jst.server.tomcat" and the versions
will be strings like "3.2", "4.0", etc.
