I'm working my way through Chapter 2 of Java Persistence with Hibernate and have run into a problem.

On page 65, there is an Ant taskdef for doing a schema export. However, when I run that Ant task, I get this error message:

BUILD FAILED
java.lang.NoSuchMethodError: org.hibernate.tool.hbm2ddl.SchemaExport.setHaltOnError(Z) Lorg/hibernate/tool/hbm2ddl/SchemaExport;

Presumably this indicates that I'm missing a jar file in my build path. (I'm using Eclipse.) However, I'm unable to figure out what is missing.

I have hibernate-tools.jar in there, but when I browse through that jar file, I see a package named org.hibernate.tool.hbm2x, but not one named org.hibernate.tool.hbm2ddl.

Am I missing a jar file? Here's what I have in my build path:

antlr-2.7.6rc1.jar
asm-attrs.jar
asm.jar
c3p0-0.9.0.jar
cglib-2.1.3.jar
commons-collections-3.1.jar
commons-logging-1.0.4.jar
dom4j-1.6.1.jar
ehcache-1.1.jar
hibernate-tools.jar
hibernate3.jar
jta.jar
log4j-1.2.13.jar
sqljdbc.jar

I'm using Java 1.5.0_10, Eclipse 3.2.1, Hibernate Core 3.2.2, Hibernate Tools 3.2.0 beta9, and Microsoft SQL Server on Windows XP.

Here's the full console output of the ant task:

After I posted that message, I noticed that the output of the ant build was showing a Hibernate environment of 3.0 rc 1(!), not 3.2.2. I investigated and discovered that I was using an old hibernate3.jar file. I replaced it with the 3.2.2 jar file and suddenly it works!

So, in answer to my own question, org.hibernate.tool.hbm2ddl.SchemaExport is in the hibernate3.jar file.
