Re: [appfuse-user] appfuse 2.0.2 gen-model and join columns?

[Matt Raible]

To implement the fix described below, you'll have to run "appfuse:copy- 
templates" and then modify the appropriate .ftl file in the imported  
templates.

Matt,

Thanks but I found a fix.  FYI, the error below says this is the
offending
line.

${pojo.generateJoinColumnsAnnotation(property)} [on line 11,  
column 15 in

If works beautifully if you add a parameter to that method so it  
looks
like
this in appfuse/model/Ejb3PropertyGetAnnotation.ftl:

${pojo.generateJoinColumnsAnnotation(property,cfg)}

In the newer version of hibernate tools, that method needs the
configuration
as the second argument.

If you simply put ",cfg" there, it will fix it.

Wow. It took me about 4 hours to figure this out.

Thanks for taking the time to figure this out. Can you please enter  
an
issue in JIRA so we can solve it for the next release?

http://issues.appfuse.org/browse/APF


Please any advice? Do people really use this gen-model tool  
heavily?  I
see
a number of "to do" comments in the code. Is there a more powerful,
better
recommended reverse engineering tool for JPA/ hibernate?

The gen-model plugin re-uses a lot of what the Hibernate3 Maven  
Plugin
does, but adds some AppFuse-specific tweaks.

Matt


The appfuse:gen seems to work better.

With appfuse 2.0.2 for struts basic and hibernate, I get the error

(with stack trace) when running appfuse:gen-model  This is an

appfuse:gen-model works like a charm on any individual table or  
tables
without inter-dependencies.

But as soon as you include any two tables with a foreign key
relationship,
this error happens.

We are aware of this issue and don't have a solution currently.

Matt


hibernate.reveng.xml is setup as recommended in JIRA and the  
Wiki for
Oracle
already.

The Oracle foreign key relationship looks like this (an  
excerpt)...

"INVESTIGATINGAGENT" NUMBER(8,0),
FOREIGN KEY ("INVESTIGATINGAGENT")
        REFERENCES "COREDBA"."EMPLOYEE" ("EMPLOYEEID") ENABLE

And the employeeid looks like this:

"EMPLOYEEID" NUMBER(8,0) NOT NULL ENABLE,

I scoured the internet in a vain attempt to find some guidance  
already
out
there.
Please help.
