ReverseEngineeringStrategy problem

hi,

i'm having a problem with my custom rev eng strategy:
package reveng.strategy;

import org.hibernate.cfg.reveng.*;

public class BCOReverseEngineeringStrategy extends DelegatingReverseEngineeringStrategy
{
public BCOReverseEngineeringStrategy(ReverseEngineeringStrategy delegate)
{
super(delegate);
}

public String columnToPropertyName(TableIdentifier table, String column)
{
//if(column.endsWith("PK")) {return "id";}
// else { return super.columnToPropertyName(table, column);}
return column;
}
}

the problem is that ant does't know about this class; it is putted in the classpath of hibernatetool task; in fact i build a jar containing this class and i putted in the classpath; the jar is in the same dir with BCOHibernate.reveng.xml; ant knows about the reveng xml because the output says :

Code:

INFO: Override file: D:\eclipse fondi workspace\BancaCorrispondenteOnline_tests\varie\svil\svil_lib\BCOHibernate.reveng.xml

but it does'n know about the jar ; why ? it is in the same dir with the reveng xml, the jdbcconfiguration strategy attribute is

Code:

reversestrategy="reveng.strategy.BCOReverseEngineeringStrategy"

the reveng/strategy/BCOReverseEngineeringStrategy.class is the only thing that is contained in the jar.....i see no problem in all i've done;

here is the full buil.xml

BUILD FAILED
java.lang.NoClassDefFoundError: reveng/strategy/BCOReverseEngineeringStrategy (wrong name: varie/svil/svil_hibernate/reveng/strategy/BCOReverseEngineeringStrategy)

Total time: 1 second

the dir varie/svil/svil_hibernate is the dir where the source and class are ; how did ant pick up this dir ??? and not the dir of the jar ???

thanks,
Viorel

and the jar does not contain that dir structure ?

the jar contains ONLY the reveng/strategy/BCOReverseEngineeringStrategy.class and the metainf file;

the oracle driver zip from the same dir is also recognized..because if i run without my reveng strategy it loads the class OracleDriver.

thanks,

so somewhere in your paths you must be referring to the root of your directories....something is "mixed' up at least.

originally, the build had:

Code:

<jar destfile="${varie.svil.lib}/revengStrategy.jar" basedir="${varie.svil.hibernate}"  includes="reveng/strategy/BCOReverseEngineeringStrategy.class"/>

(you can see the first post)

i tryied to run the build with :

Code:

<jar destfile="${varie.svil.lib}/revengStrategy.jar" basedir="${varie.svil.hibernate}/reveng/strategy/"  includes="BCOReverseEngineeringStrategy.class"/>

clearly didn't work because the jar contained one file and no directory;
so i corected to the original <jar> tag; i runed again....and maggivally worked......i guess it's about refresh....i don't know...but now i'm very pleased that it's work cause it began to drive me crazy...

thanks,
Viorel
