Re: [ptp-dev] Fw: PTP java.lang.ClassNotFoundException: for com.sun.xml.internal.bind.v2.ContextFactory

Greg
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-osgi that 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?
