[Xdoclet-user] Ant + Hibernate

Philippe Blockmans Mon, 29 Aug 2005 06:25:05 -0700

Hi all,

I’m trying to generate Hibernate mapping files using the hibernatedoclet task.

Each I try to run it, I get the same error (stack trace below): java.lang.NoSuchMethodError: org.apache.tools.ant.AntClassLoader: method getClasspath()Ljava/lang/String; not found

I’ve checked, the class and method are existing.

I use ant 1.5.3-1 and Java version is 1.4.2

Any help would greatly appreciated.

Kind regards,

Philippe Blockmans
