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

It looks like what's described at http://www.descher.at/descher-vu/2019/01/java-11-jaxb-and-osgi/ is what's needed to get the right plugins. I found the following plugins at these exact levels
com.sun.activation:javax.activation:1.2.0
javax.xml.bind:jaxb-api:2.4.0-b180830.0359
com.sun.xml.bind:jaxb-osgi:2.4.0-b180830.04

at https://mvnrepository.com, where I figured out how to download the jar files. I put the jar files in a local directory and updated the photon.target target definition file to point to that directory.

When I started a runtime Eclipse PTP instance, opened a run configuration and selected a connection name in the resources tab, I no longer got the missing class exception for the ContextFactory class. I couldn't actually run an application since I don't have the right MPI installed on my system, but I think this is encouraging.

Hi Dave,

Thanks for looking into this. I'll try to take a look later this week.

      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?
