Reverse Engineering Strategy

Jake123 · **Posted:** Thu Sep 14, 2006 5:28 pm

Hi,
I have created a custom reverse engineering strategy for getting rid of Sets for foreign keys. I want to use this instead of adding xml code in my reveng.xml file to exclude them.
My RevEngStrategy looks like this:

Code:

public class RevEngStrategy extends DelegatingReverseEngineeringStrategy {

   public RevEngStrategy(ReverseEngineeringStrategy delegate) {
      super(delegate);
   }
   
   public boolean excludeForeignKeyAsCollection(String keyname, TableIdentifier fromTable, List fromColumns, TableIdentifier referencedTable, List referencedColumns) {
       return true;
   }
   
}

My question are: How do I use this through eclipse? I generate hbm.xml and pojos in eclipse and all my other classes from ant.

Thanks
Jacob

set the full class name in the Reverse Engineering strategy field when doing the reverse engineering.

I tried that, but I get a java.lang.ClassNotFoundException.
"Could not create or find \MycompanyPersistence\hibernate\src\java\com\mycompany\persistenceutils\RevEngStrategy.java with one argument delegate constructor"

the path looks like this:

\MyCompanyPersistence\hibernate\src\java\com\mycompany\persistenceutils\RevEngStrategy.java

Thanks
Jacob

One update:
I wrote this path myself, when I try to use the browse... button I only have this under "Choose a reverse engineering strategy:
org.hibernate.cfg.reveng.ReverseEngineeringStrategy

and under matching types I have:
ReverseEngineeringStrategyUtil - org.hibernate.cfg.reveng -C:\DevArea\MycompanyPersistence\hibernate\toolslib\hibernate-tools.jar

I can not browse to my own class....

you should put a *class* name not a *file* name.

so it should be: com.mycompany.persistenceutils.RevEngStrategy

Hi Max,
sorry for that, but when I changed that it still does not work.

Now I get this error:
"org.hibernate.console.HibernateConsoleRuntimeException: Could not create or find com.mycompany.persistenceutils.RevEngStrategy with one argument delegate constructor"

I posted in my first posting my revengstrategy class... have I done anything wrong in that? Or why cant the console find it"?

Thanks again
Jacob

code looks fine.

is the class actually compiled into one of the paths you've put into the console configuration ?

Yes. in my compiled directory I find the class: It is located in
target\classes\com\mycompany\persistenceutils\RevEngStrategy.class

So what else can be the problem?

and target\classes is in the console configuration class path ?

Jake123 · **Posted:** Fri Sep 15, 2006 11:07 am

the target/classes is my output folder in eclipse.

so the package declaration looks like this: com.mycompany.persistenceutils
for the RevEngStrategy class.

I thought that the console is checking my output folder and therefor start looking in target/classes after the class name I specify.
So I only put com.mycompany.persistenceutils.RevEngStrategy in the placeholder for reveng strategy in the Hibernate Code Generation console...

ok - please read what i'm asking for!

Is it in your *console configuraiton classpath* ?
(i am *not* asking about wether it is in your eclipse project or anywhere else)
