[Xdoclet-user] Ant + Hibernate

[Philippe B. <Phi...@ad...>]

Hi all,

=20

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

=20

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

=20

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

=20

I use ant 1.5.3-1 and Java version is 1.4.2

=20

Any help would greatly appreciated.

Kind regards,

Philippe Blockmans
