    Issue with 'seam generate-entities'

    David Cloutier Newbie

      Hi,
      I am trying to lear seam, going through the doc/tutorials etc and I have come up with an issue that I can't find in the Jira's or forum.

      I am using SEAM 1.6, with jdk 1.5.08 on Windonws 2000. Here's the error I get:

      ================================================
