[Middlegen-user] finder methods

[Brent Craig]

I am using mysql. When I define a numeric type in mysql the bean method
representing the field returns and sets a java.math.BigDecimal. How can I
change this to another java type?

Also, if I want to dictacte the finders that I want to be created (instead
of all fields except pk's and fk's) do I need to modify the entity-20-cmp.vm
file?

Thanks

Hi. I assume you're using Middlegen from CVS.

Run Middlegen in gui mode. Select the columns you want to change in the
upper panel and modify the java type in the combo in the lower panel. When
you exit, Middlegen will remember your settings in your xxx-prefs.properties
file, so you can run without gui in the future and get the same result.

No need to change the template. Use the new, nifty logical predicates:

You can only specify global rules, not on a per-table basis.

If you want full control of the finders per table, turn off generated
finders, e.g. with
<finders>
<false/>
</finders>

and use merge files to add custom @ejb.finder tags in the generated beans
http://boss.bekk.no/boss/middlegen/plugins/cmp20.html (look for
pluginname-tablename-class-comments.txt at the bottom)

The airline sample illustrates how both of these features are used (some of
it is commented out for you to un-comment).

You should do a CVS update. I just fixed a little bug related to this.

HTH,
Aslak

Thanks
