Last night, URI(http://hibernate.sourceforge.net/hibern ... ng-3.0.dtd) for hibernate DTD was down and then I can't use hibernate tool to work properly. I read some docs about doctype and know I can use local DTD file or embed DTD in xml file. I don't like the later way since it makes my xml file long and look ugly.

If I use local DTD file, how can I specify file path so it can be used in both hibernate tool and tomcat server? Thanks!

Or does anyone know a smart way to swtich from remote DTD to local one when URI is down?

if you use the DTD references that is in all our examples/docs then everything works fine without a internet connection....

What do you mean? I used DTD reference from hibernate tool doc as below,

<!DOCTYPE hibernate-reverse-engineering SYSTEM "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

This is the ONLY dtd file I found from doc(http://www.hibernate.org/hib_docs/tools ... ml_single/), which requires Internet connection obviously.

and what is the problem with that ?

works for me in my end when i don't have any internet access.

What is your concrete problem ?

I used dom4j to write an ant task to generate revegn.xml file dynamically. It will read my template reveng.xml as below but stops working if remote dtd file isn't available.

document = new SAXReader().read(new File("template.reveng.xml"));

After I have a complete reveng.xml file for multiple tables, I will call hibernate tool to generate hbm files for these tables.

If you know how to let dom4j ignore dtd when reading xml, please let me know.

eh - what do you need to write a reveng.xml file for dynamically ?

please tell ...

to read it use the DTD entity resolver used by hibernate (and the tools) to resolve it from the classpath.

look for XMLHelper.DEFAULT_DTD_RESOLVER.

ah - you are the one who wanted to reveng multiple tables as input to the tools...got it.


(for me it would make more sense to write a reveng strategy that just took the list of table names instead of generating...but that is just me ;)
