hi,

I want to make persistant such a class,

public class MyData extends OpTrBaseClass{
double[] dependentValues;
double[][] relatedValues;
String[] relatedNames;
int size;
.....
...
...
}

I look for any custom collection type by UserCollectionType interface I could not find how can I make persistant double[][] relatedValues attribute?

thanks.....

Hi,
in above code sample "extends" part is ignorable...
