class not found error adding new payment gateway

[Cavs123]

hi there,

I have had a problem adding a custom payment gateway, cpay, to KonaKart. I used an existing module payjunction, copying its files and modifying them according to the guide. I added the new payment module in the various config files. I build the new custom jar files with the ant build file and copied them to:
C:\Program Files\KonaKart\webapps\konakart\WEB-INF\classes
and
C:\Program Files\KonaKart\webapps\konakartadmin\WEB-INF\classes

When I run the KonaKart admin app, I get the following error (below). It says that the class com.konakarta
dmin.modules.payment.cpay.Cpay is missing but this is in one of the jar files I placed in both locations. Any ideas would be really helpful.

Actually,

The path I placed the jar files in was

C:\Program Files\KonaKart\webapps\konakartadmin\WEB-INF\lib and not C:\Program Files\KonaKart\webapps\konakartadmin\WEB-INF\classes

same for the konakart directory

The problem appears to be this, from the exception:

com.konakart.app.KKException: The configuration at index 7 Cpay is null


Check your source code.  Are you creating a configs array that's too big?

You should reduce the [8] that was used in payjunction to however many config elements you have in CPay


        if (configs == null)
        {
            configs = new KKConfiguration[8];
        }

Thanks a million for your help. You were right. I changed the array to match my configurable items and the module is now loaded in the admin app. One step closer!
