Hi,

We are using middlegen to extract the hbm.xml file from a Database Table and also the corresponding java file using hbm2java but we are looking at creating only one Java file.

Right now, if we are using middlegen and hbm2java against a database table ORDER, we get Order.java and OrderPK.java and we are wondering if there is a way to generate only one file Order.java which has all the contents from both Order.java and OrderPK.java.

Is this possible by changing the template file that came with middlegen?

Thanks

Middlegen does not (currently) generate any Java code. Its hbm2java that generates the java code from the hbm's that middlegen has created. You can edit the velolcity script to customise the output. Having said that, there is a Ant option documented on the wiki to generate the Composite Key as an integrated key rather than an external key. See the Middlegen Wiki page for the details.

Note: Integrated Composite keys is not the recommended approach.

Hi,

I found a solution for my own question. In order to create only one Java File for a Database Table instead of creating two files (one seperately for Primary key), basically in your build.xml inside the middlegen target, under the hibernate plugin, just add

genIntergratedCompositeKeys="true"

This will only create one Java file

THanks.

Great - For others reference - this is in the documentation as I pointed out.
