Hi,
I use JSR220ORM plug-in for eclipse to create ddl file but there are lots of bugs in ddl file, is there another tool for generating DDL?Any tips would be appreciated.

If you like ant, take a look at hbm2ddl at http://www.hibernate.org/hib_docs/tools/ant/index.html

If you would rather generate the DDL with manual java, try something like this:

Thank you for your help. But i can not launch the ant tool (hibernate-tool) successfully. It seems that this tool depends on specified version of hibernate-annotation.jar, persistence.jar and hibernate.jar. And the linked page does not give any hint about which version should i use. :( After lots of NotFoundClass, NotFoundMethode i give up this approach.

Now i try to use manual codes to generate DDL, but i have also no idea how to begin :( Should i use AnnotationConfiguration or something like this?

your dependency issues should go away as long as you are using the hibernate.jar that is packaged w/ whatever distribution you got the tools from (hibernate-tools.jar ) .

if you are set on the SchemeExport way, you'll need AnnotationConfiguration if the mappings are in annotations, although you can use AnnotationConfiguration w/ an annotationless mapping model.

take a look at this for SchemaExport info

Yes, after using all the jar from hibernate-tools/lib, my dependency problem is resolved. :) But now i encounter a new one. The generated DDL file is empty.http://forum.hibernate.org/viewtopic.php?t=950014.

Thank you dennis, i have created the ddl using simple manual codes by schemaExport. It is very simple.



I am a newbie of hibernate, your information helped me a lot.:))
