[news.eclipse.rt.eclipselink] ddl-generation

[Marc Schlegel <my.mailing.lists@xxxxxx>]

Hello again

In addition to my prior post, I have another problem with DDL generation.

When I use drop-and-create-tables I get an exception when the tables are not 
available at drop time.
When I use create-tables I get an exception when the tables are already there.

Why is drop-and-create-tables not just ignoring it when there are no tables to 
drop. Thats fine...it can continue with the creation. I dont want to change my 
persistence.xml every time I run my testcases or drop tables in the database 
manually.

Furthermore I get exception regarding a table called SEQUENCE (sometimes telling 
me that it is missing, or that it is already there).

I guess I am doing something wrong in my top-down-approach. I know that in real 
scenarios usually bottom-up is used, but right now I am just playing around how 
to organize my object and how to map it...and currently EclipseLink seems to 
have some problems with that.

Can somebody explain what I might do wrong or what I have to be aware of.
Thanks
