I want to use JAX-WS web services in my project, for that I came to know about the WTP tool.
So, grabbed a fresh copy of eclipse and went to the home page : WTP. It says to download WTP from the update site http://download.eclipse.org/webtools/milestones.
I tried to install from this location but eclipse shows the following error :
Eclipse Galileo, if you downloaded the "Eclipse for Java EE Developer's" edition already contains WTP.
The Eclipse distributions named after the moon of Jupiter (Ganymede, Galileo, etc) are bundles that contain the base Eclipse IDE plus a number of plugins pre-installed so that they are immediately usable by the targeted programmers.
