Re: [Xdoclet-user] [schemaexport] net.sf.hibernate.MappingException: persistent class [T1] not found

O Victor tem razão, o problema que a SubTask de geração dos schemas do Hibernate, exige que os arquivos hbm estejam no classpath, independente de ser ou não no mesmo diretorio das .class, o que geralmente não é um boa coisa quando se leva em conta boas práticas de organização do código de um projeto. Como pude perceber suas classes estão num diretório <classes.dir> enquanto os hbm estão no diretorio <gen.src.dir>. Experimente colocar um classpath personalizado na TARGET <gerenerateS>, assim:

Boa sorte!

put your *.class and *.hbm.xml in the same dir

{class.dir}
       |------*.class
       |------*.hbm.xml

si hablaras español me seria más comodo ayudarte :-)
