Middlegen is not activly maintained anymore. I recommend taking a look at
Hibernate Tools if you need to reverse engineer your database:
http://docs.jboss.org/tools/2.1.0.Beta1/hibernatetools/html/reverseengineering.html

Hi,

I am new to middlegen. I need the following details:

1) How to setup middlegen.

2) Using Middlegen with hibernate3

Any help is greatly appreciated.

Regards,

Sripriya

This patch contains codechangs to help ANT task specify separate
interfaces for tables.

example:

<middlegen 
appname="${program.name}-${module.name}" 
gui="false" 
databaseurl="${database.url}" 
driver="${database.driver}" 
username="${database.user_name}" 
password="${database.user_pwd}" 
schema="${database.user_name}" 
includeViews="false">
<table name="SOME_TABLE" implements="Interface" />
<table name="OTHER_TABLE" implements="Some other interface" />
<table name="THIRD_TABLE" /> <!-- no interface -->
<hibernate 
destination="${dir.generator.mappings}" 
genXDocletTags="true" 
standardCascade="all-delete-orphan" batchSize="500" />
</middlegen>

Sounds fine - send the source patches in and someone will check it out and
commit the changes.

Subject: [Middlegen-devel] Separate interfaces and extends for tables.

Isn't it helpful to have in middlegen ANT task the option to specify
implements interfaces for each table separatly

example:

<middlegen 
	appname="${program.name}-${module.name}" 
	gui="false" 
	databaseurl="${database.url}" 
	driver="${database.driver}" 
	username="${database.user_name}" 
	password="${database.user_pwd}" 
	schema="${database.user_name}" 
	includeViews="false">
	<table name="SOME_TABLE" implements="Interface" />
	<table name="OTHER_TABLE" implements="Some other interface" />
	<table name="THIRD_TABLE" /> <!-- no interface -->
	<hibernate 
                 destination="${dir.generator.mappings}" 
                 genXDocletTags="true" 
                 standardCascade="all-delete-orphan" batchSize="500" />
</middlegen>

Right now we can only have same interfaces for all tables.

I made some modifications and this works fine. If middlegen dev team thiks
its reasonable then i can send my modifications in middlegen source also.

No. Middlegen needs a major rewrite to be decoupled from Ant. The project
is pretty much passive, so you probably need to do it yourself if you want
to see some progress.

Hi,

I tried to run Middlegen without ant, but Middlegen (the class) depends on MiddlegenTask. Is there any other way to do this?

TIA,
Thiago

The lead developers have been answering your questions :-)
Having said that Evind and myself have been busy working - yes yes sad
violin sounding in the back ground.
I must admit its nice to see people are using and appreciate the tool - =
even
with minimal recent advancement.
Help is always welcome.

Yup. Should even be an example of usage here:

Not sure how well this stuff works. Think it was developed with a

pre-release of EJB 3 from JBoss, and as David points out hasn't been

maintained..

Hi,

	Thank you for you support. If you get the muild from the CVS

repository there is a plugin for EJB 3.0. It might need a tweek or two.

	Alternatively, there are other tools around. One candidate is the

hibernate tools package.

Hay eivind,

	Agreed, a cleanup exercise then move to toward a release.
	We need to focus on a few plugins. I would suggest we atleast
rate the quality of the plugins so its obvious what the status of them
is for the users.

Hey guys! Good to see some activity on the list :)

The adapter thing has not been maintained in a while. And the Struts
generating stuff using the adapter should probably be deprecated. I
suggest just using Middlegen to generate the dao layer (hibernate
files), not full application. Alternatively write your own plugin for
view.

A cleaned up release would be good! Where we remove/deprecate all the
beta-stuff (adapter, struts etc.) and focus on a few working plugins?

Sounds like your doing a good job hunting the issue down.
I am not sure how solid the adapter plugin is so your work here is most
welcome.
I would be happy to commit any changes that you determine will help fill
a few holes.

We should work toward a release - we were orginally waiting for the
EJB3.0 stuff to finalise.
Then move forward. Thanks for your help.

Ok, I think I found out what the culprit was.
Version: latest from the CVS.
Context: I am using the adapter plugin with hibernate persistence layer.
in hibernate-findRelation.vm : line 3
retVals.add(${persistenceObjectName}.${hbmTable.getGetterName(${relation
shipRole})}());
HibernateTable's getGetterName was method invoked with a
RelationshipRole object as an argument. The problem : the
RelationshipRole is a decorated one, with origin and target table set to
decorated AdapterPlugin. The inherited getGetterName method eventualy
called the inherited getVariableName. getVariableName compares the
origin table of the RelationshipRole with 'this'. Unfortunately the call
to getOrigin uses plugin as a key, and we are in a HibernateTable here,
hibernate's plugin is used here, resulting a null because the
RelationshipRole only has entries created by the AdapterPlugin. The
method throws IllegalArgumentException because null != a HibernateTable.
I think this whole thing is caused by the new RelationshipRole
decoration stuffs. Any ideas?

Ok, I think I found out what the culprit was.
Version: latest from the CVS.
Context: I am using the adapter plugin with hibernate persistence layer.
in hibernate-findRelation.vm : line 3
retVals.add(${persistenceObjectName}.${hbmTable.getGetterName(${relationshipRole})}());
HibernateTable's getGetterName was method invoked with a
RelationshipRole object as an argument.
The problem : the RelationshipRole is a decorated one, with origin and
target table set to decorated AdapterPlugin. The inherited
getGetterName method eventualy called the inherited getVariableName.
getVariableName compares the origin table of the RelationshipRole with
'this'. Unfortunately the call to getOrigin uses plugin as a key, and
we are in a HibernateTable here, hibernate's plugin is used here,
resulting a null because the RelationshipRole only has entries created
by the AdapterPlugin.
The method throws IllegalArgumentException because null != a HibernateTable.
I think this whole thing is caused by the new RelationshipRole
decoration stuffs.
Any ideas?

HI,

	Yes I am still active on the list.

Actually I'm wondering about the Plugin mechanism. What does the
decoration means? Is it related to the famous Decorator pattern? 

Yes its based on the Decorator pattern and provides the mechanism for
each plugin the customise the use of the meta data supplied about the
database resource.  Plugins are easy to create lots of examples.

	Hope this helps.

Cheers David.

Hi,
anybody still active in this list?
The sourceforge archives has no 2006 entry at all.
I'm trying to build a custom plugin, but first I must to learn the inner
working of Middlegen. I checked out the CVS yesterday, and now can't get
the sample to work (the 2.1 version worked but has strange errors about
duplicate methods). I redirected the database to my MySQL 5.0, the
schema is custom one (not the one from the sample). [middlegen]

Hi!

Working on database I found difficult to look at all the DB constraints when
one
is working on java. In particular a developer must know all the DB constraints
in order to prevent DB errors in CRUD operations.

Now... middlegen is able to create java classes from database tables.

So my idea is the following:
Middlegen can also create a copy af the database constraints... that is...
If the field "name" in the table "account" has the "NOT NULL" constraint it's
possible to automatically generate this constraint (by inserting some code that
throws an exception) in the java class so that the programmer can manage the
errors. In this way the errors can be discovered before the command is executed
by the database and without have to parse the database error.
Moreover change in the database can be automatically adjusted by regenerating
the java class.

The programmer can also extend this java class in order to:
1) insert his own constraint to the class
2) automatically change the parent class if the database constraints change.

Let me know what you think about this idea.

Best regards,
Luigi

Peter,

	Thanks for the offer. I would be happy to look a the work and
submit it. I have been a little quite lately due to my workload. I have
some other patches to commit as well so it would be best if I do all of
them at the same coding session. 

	Thanks for the effort.

Cheers David.

Subject: [Middlegen-devel] Hibernate 3.x updates

I would like to submit changes to the Hibernate plugin to be be more 
compatible with the latest 3.x release of the Hibernate core. I am new 
to working on open-source projects and would like to contribute to this 
one specifically since it is the only one of its kind.

Please let me know the protocol of working with these and I will kindly 
submit the updates we are currently using in our development and 
production environments.
