[SOLVED] Install ArgoUML into Eclipse Indigo throw an error

Install ArgoUML into Eclipse Indigo throw an error

I was trying install ArgoUML into Eclipse Indigo, anyhow I hit this error during the installation and proceed, any clue to solve this problem?

Cannot complete the install because one or more required items could not be found.
  Software currently installed: Eclipse IDE for Java EE Developers 1.4.1.20110909-1818 (epp.package.jee 1.4.1.20110909-1818)

Solution

I would guess that you are missing a required update site. From the error log, org.eclipse.jst.ws.jaxrs.core [1.0.301.v201108240656] is required, but couldn't be found. A quick google search shows that this should be part of WTP 3.2.x. You can find all the update sites for WTP here; http://download.eclipse.org/webtools/downloads/ Choose one of the 3.2.x update sites and make sure that you have "Contact all update sites..." checked when you try to install ArgoUML.
