Hi,

Installed Haskell Platform 2010.2.0.0 on Windows, then install EclipseFP 2 Latest Release 2.0.2 on Helios 3.6.1. JDK 1.6.0_21. But the internal Scion server cannot be built, so I cannot compile my Haskell code.

How to solve it?

The following error message is displayed on the Eclipse console when I launch Eclipse:
