| Unfortunately this is the problem. Projects hosted on Eclipse can’t be built using arbitrary components from a maven repository. Everything has to be obtained from Eclipse repositories, and from what I’ve been able to determine, the latest jaxb version is 2.2.0 which doesn’t seem to work. I’ve been looking at using Eclipselink but haven’t been able to get that to work either.
Also, it would be worth checking that Dave’s solution works for Java 8 as well as Java 11/12. Whatever the solution is, it also needs to work with both versions.

Dave, is it possible that Greg didn't copy the three plugins to a local directory and instead tried to reference them directly from the server?Greg, with Dave's approach, will you need to package those plugins with PTP?

I'm not sure what's different. I have a Java 12 runtime. I downloaded the java-activation-1.2.0,jar, jaxb-api-2.4.0-b-180830.0359.jar and jaxb-osgi-180830.0438.jar from the maven repository files into a local directory, added that directory as a local repoistory in the photon.target file, and changed the import for com.sun.xml.bin in the org.eclipse.ptp.rm.jaxb.core MANIFEST.MF file to com.sun.xml.bind.v2. Then I reloaded the target definition file and started a PTP runtime instance.
I was able to open the run configuration dialog, pick any target system configuration and pick a remote connection name. Then the resources page would fill in properly.
If I backed out those changes and ran again using the Java 12 runtime, I got the error for the missing class.

Hi Dave,
Yes, I’ve spent the better part of a week on it and I’m still no closer… I’ve tried everything, including creating a fragment with the dependencies but I’m still getting the error.

Looking at this further, it seems that CDT has solved this or a similar problem
https://www.eclipse.org/lists/cdt-dev/msg33366.html
https://bugs.eclipse.org/bugs/show_bug.cgi?id=542644
I also found this, which suggests using com.sun.xml.bind:jaxb-osgi to get the missing JAXB code, where I found https://mvnrepository.com/artifact/com.sun.xml.bind/jaxb-osgithat seems to point to the location to get it from.
I don't know if this helps or is even possible to use in an eclipse.org-hosted project

I'm looking at this problem since it affects my plugin once Java 8 is no longer supported. I'm not sure I'm anywhere near on the right track to figure this out. I found quite a few references to this problem within the past year by Google search using the words ContextFactory and Eclipse, a number of which refer to PTP bug 541264
My understanding of the solutions suggested are to use versions 2.2.0 of the com.sun.xml.bind and javax.xml.bind, which I think means I need to find repositories that have these versions of the packages.
I tried updating the photon.target target definition file to use a later Orbit repository, I20190320195810 which seems to have these, but that did not help. I also found https://www.jesperdj.com/2018/09/30/jaxb-on-java-9-10-11-and-beyond/which explains how to specify a dependency for a maven build, but I'm not sure where this gets specified.
Am I anywhere near the right track to figure this out?
