It's can be some nerwork problems, can you try once more time?
Yes, I tried 2 or 3 time on Monday and 1 or 2 yesterday (Tuesday).
Google reveals many of these exceptions as not being specific to JBoss Tools.
Does it work fine with other sites?
Is there any additional output in the error log view - i.e. a full stack trace ?
Are you using something else than just plain Eclipse to install it on ?
I use just plain Eclipse to install.
I tried other install just to check and you are right, it has the same problem (I tried Axis2 Tool from http://download.eclipse.org/releases/helios) :
"An error occurred while installing the items
session context was:(profile=SDKProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null --> [R]javax.mail.glassfish 1.4.1.v201005082020, action=org.eclipse.equinox.internal.p2.touchpoint.eclipse.actions.InstallBundleAction).
Error while loading manipulator.
Error while loading manipulator."
I installed perl, php and xml stuff a few months ago without problems. I'll check in Eclipse what is happening now I know the problem is not from jboss.
Thanks a lot for your help,
I have found my eclipse installation had problem, I have reinstalled eclipse and now everything is ok.
