When I ran into this problem before, I found another activiation.jar in
my classpath. After removing it, the problem went away.
Maybe, you could try doing a search for "activation.jar" with windows
explorer.
Also, make sure the activiation.jar file is in the 'lib' directory of
"<wtpInstallDirectory>/eclipse/plugins/org.eclipse.wst.ws.apache.soap_1.0.0/
". In fact, all the jars need to be in a "lib" directory, so create the
folder if one doesn't already exist.
And finally, you could try starting up eclipse with "-clean".
If after more tinkering and none of my suggestions work, maybe we should
start tracking this problem through a bugzilla bug. Please feel free to
open one.
