[Middlegen-user] 'create' methods on *remote* home with *local* interface parameters

[Russell Black]

First, I want to say God Bless Middlegen!, and kudos to Aslak and the other developers. This will be an enormous time saver if I can get it to do what I need.

When I configure middlegen to generate remote interfaces (viewtype="remote" in the cmp20 subtask), it generates create methods which take local interfaces as parameters.

For example: a Choice belongs to a Scale, and the middlegen-erated create method in ChoiceBean looks like this:

public foo.interfaces.ChoicePK ejbCreate( int number, java.lang.String text, boolean na, icoachplus.interfaces.ScaleLocal scale )

Resulting in an xdoclet-generated *remote* interface that looks like this:

public foo.interfaces.Choice create(int number , java.lang.String text , boolean na , icoachplus.interfaces.ScaleLocal scale)

This causes two issues. First, since it didn't generate any local interfaces, it won't compile. I can make it compile by using viewtype="both", but the real issue in my mind is: what good is a create method on a remote interface that takes local interfaces as parameters? A remote client of course does not have access to local interfaces.

I love the CMR feature introduced in EJB 2.0, so I want to use local interfaces where I can, but I'd really like to be able to create objects with the remote interfaces where running in the same JVM is not an option.

Hey I looked through the Middlegen buglist and seems there are some bugs
related to this:

http://sourceforge.net/tracker/index.php?func=3Ddetail&aid=3D596249&group_i=
d=3D36044&atid=3D415990
http://sourceforge.net/tracker/index.php?func=3Ddetail&aid=3D615463&group_i=
d=3D36044&atid=3D415990

I see from a comment by Aslak that CMRs do not apply to remote beans at
all. So I guess the fix to this would be something like this (I might be
wrong here):

local - Create methods with CMR fields linking to other local interfaces.
remote - Create methods with just the fields (like flightId instead of
flightLocal)

Anyone has time to look into this? Involvement from more users would be
really good I think, as the developers are really busy for the
moment. Submitted patches/solutions are so much quicker to add than
sitting down and figuring things out..
