I have a JUnit test which tries to send an email using the Spring org.springframework.mail.javamail.JavaMailSenderImpl class.
When run from inside Eclipse, I receive a NoClassDefFoundError because it is unable to find com.sun.activation.registries.LogSupport. I have activation-1.1.jar on my build path but this is being ignored and overriden by javaee.jar in the com.genuitec.eclipse.j2eedt.core-5.5.0\data\libraryset\EE_5 directory.
I can run the test successfully outside Eclipse where I can control which jars are on the classpath and it works fine with the activation-1.1.jar which is in the project's lib.
I can run the test successfully from within Eclipse if I rename the javaee.jar, but I can't do this as a long term fix because this stops the project building.
How can I persuade Eclipse/MyEclipse to use the activation-1.1.jar instead of the version in the plugin?
I'm using MyEclipse 5.5.0. |

| If you right click on your Project and go to Build Path > Configure Build Path > Java Build Path > Order and Export and move the activation-1.1.jar up the list, does it help? |

Thanks for the suggestion, but unfortunately this doesn't work because what seems to be picking up the javaee.jar is the MYECLIPSE_LIB_HOME variable which can be seen by going to Window|Preferences|Java|Build Path|Classpath Variables.
I assume that these take effect before the individual project library files are loaded and I haven't been able to find a way of indicating that a project file should take priority.
I've looked at a colleague's later version of MyEclipse (6.0) and it doesn't look like an upgrade would solve the problem as the javaee.jar is still missing the LogSupport file so I'm not sure what I can do to fix the problem.
Any further suggestions would be very welcome. |

| Thanks for the information. The issue is now resolved by removing the JavaEE Libraries from the Bootstrap entres in the classpath shown in the JUnit Run Configuration tab. |
