What could be the reason? It is really strange that the application worked before and passed the SVN codes, and then when I exit and restart everything that I get this error ...

It almost certainly looks due to incompatible versions of the "core" and "mapper" cans. You are probably using incompatible versions through the classpath.

The problem you are facing is related to updating the Google App Engine SDK (I think 1.6.1?).

  • google_sql.jar
  • --ASL-1.6.3.jar
