[Middlegen-user] Data object / Value object generation

[Bill Pfeiffer]

Is the value object generation stuff in the latest version of Middlegen? I'm using the data object generation but middlegen only exposes it through the local interface for some reason and I would like to have it exposed for both local and remote interfaces.

BTW, is there a specific reason why the Data object is only exposed via the local interface. I manually edited the middlegen generated file and set the @ejb.interface-method view-type tag for the getData to "both" and it generated and compiled fine.

Any help here would be appreciated.

Thanks,

Bill Pfeiffer

Value objects are not yet supported: http://tinyurl.com/6qa1

CMR doesn't work with remote interfaces, so supporting value objects through
both remote/local interfaces is a bit tricky. I never got around to make
Middlegen generate "remotable" classes in a way that doesn't stink. If you
have a patch, feel free to share it with us.

Please send mail as plain text (not HTML), so we can inline the answers.

I don't know if this will help you, but if you want Middlegen to
create the @ejb.value-object xdoclet tags for you, you can create a
custom entity-cmp-20.vm velocity template file based on the
distributed file, where you put these lines just below the
#if( ${plugin.dataobject} )
...
...
#end
lines:

-------------- snip --------------
#if( ${plugin.dataobject} )
* @ejb.value-object
* name="${table.beanName}"
* extends="com.your.AbstractValueObject"
* match="*"
* instantiation="eager"
*
#end
-------------- snap --------------

Now rerun Middlegen on your database to get the new code.
When xdoclet is run over the Middlegen code you just need to
specify <valueobject/> within your <ejbdoclet> ant task and you'll end
up with what you might want.
