Subject RE: [C2] Connection pool problem with SQL
Date Tue, 05 Jun 2001 14:53:37 GMT
Ok, my esql problems went away with a cvs update of the cocoon 2 source
tree. Still getting the same ProcessingException with the "simple SQL"
example. I've made sure that my xerces 1.4 jar appears ahead of the xalan
jar.
