    Cant instantiate class: org.jboss.seam.el.SeamELResolver

      Hi,

      I'm facing a really strange problem when deploying a clean new project created with "File -> New -> Seam Web Project" in JBoss 4.2.3 GA with Eclipse Ganymede, jdk 1.5.0_16, jboss-seam-2.0.2.SP1, and the latest nightly build of JBoss Tools on Linux (JBossTools-200809130224-nightly-ALL-linux-gtk).

      To begin with, when I select "Add and Remove projects" on the JBoss Server View and I add the PruebaSeam-ds.xml and the PruebaSeam, only the last one is published in the "deploy" folder of the JBoss server. So I add PruebaSeam-ds.xml manually to the folder and run JBoss, but it throws a strange exception:

      Could it be some missing Jar?, some bad combination of versions of Jboss, seam and eclipse?

      Thanks in advance,
      Carlos.
