SchemaExport doesnt work without classes??

I've been trying to get the SchemaExport to work, but running the commandline tool is simply impossible for me... It complains about a missing Apache\Files ... Whatever that is.

However, i downloaded the Workshop example to take a look at the Ant way of doing it. And from what it looks like, i have to generate the Test.java class before i can make a SchemaExportTask with the Test.hbm.xml?? This makes no sence, where is the idea of making both of the files, one of them should be sufficient?

I tried to use the Employer example listed on:
http://www.hibernate.org/hib_docs/reference/en/html/example-mappings.html

But it just says the same:

Quote:

D:\PROGRA~1\APACHE~1\RUNWAY~1.0\src>ant topdown.hbm2ddl
Buildfile: build.xml

topdown.hbm2ddl:
[copy] Copying 1 file to D:\PROGRA~1\APACHE~1\RUNWAY~1.0\src\webapp\WEB-INF
\classes
[schemaexport] log4j:WARN No appenders could be found for logger (net.sf.hiberna
te.cfg.Environment).
[schemaexport] log4j:WARN Please initialize the log4j system properly.

BUILD FAILED
D:\PROGRA~1\APACHE~1\RUNWAY~1.0\src\build.xml:114: Schema text failed: persisten
t class not found: Employer

Total time: 2 seconds
D:\PROGRA~1\APACHE~1\RUNWAY~1.0\src>

Any help on this?

SchemaExport needs the persistent classes to do its magic.

Really?

What about the workshop...:

http://www.hibernate.org/hib_docs/online/workshop_toolset/presentation/html/img4.html

It clearly looks like you can just make the XML, generate the schema and then the POJO's...?

And if this cannot be done, is the bottomup approach the most common?

Thanks

I think i figured it out myself. The order of how things are done is wrong in the workshop.

Change step 2<->3...
