Hold on, are you saying that you are trying to upgrade from 0.6 to a
more recent release ? In that case, you might be facing (regression)
problems, indeed.
Let me ask you a few questions:
a) why use a mapping file at all, when the Java classes have been
generated using Castor's code generator ?
b) Having a member variable of type List and trying to access it as an
array ... well, is odd to me.
Can you break things down to a really simple test case that does *not*
reference multiple Java classes with tons of properties.
But let's first see what your answers are ..

Thank you for answering, Werner.
The strange fact for me is that this mapping file worked before as it is
now...
That relation field is defined as follows in the class:
private java.util.Vector relationList;
and its set/get methods are:
public void addRelation(Lom_Relation vRelation)
throws java.lang.IndexOutOfBoundsException
{
relationList.addElement(vRelation);
} //-- void addRelation(Lom_Relation)
public void addRelation(int index, Lom_Relation vRelation)
throws java.lang.IndexOutOfBoundsException
{
relationList.insertElementAt(vRelation, index);
} //-- void addRelation(int, Lom_Relation)
public Lom_Relation getRelation(int index)
throws java.lang.IndexOutOfBoundsException
{
//-- check bounds for index
if ((index < 0) || (index > relationList.size())) {
throw new IndexOutOfBoundsException("getRelation: Index
value '"+index+"' not in range [0.."+relationList.size()+ "]");
}
return (Lom_Relation) relationList.elementAt(index);
} //-- Lom_Relation getRelation(int)
public Lom_Relation[] getRelation()
{
int size = relationList.size();
Lom_Relation[] mArray = new Lom_Relation[size];
for (int index = 0; index < size; index++) {
mArray[index] = (Lom_Relation) relationList.elementAt(index);
}
return mArray;
}
these were generated with Castor's code generator long ago (v 0.96)...

First of all, thanks for answering.
That package called "classes" is located in my classpath already.

<mailto:[EMAIL PROTECTED]>>:
Hi,
as you highlighted there is a mapping that refers to a class
'classes.Lom_Relation' which could not be found. This field mapping
causes castor to search for a class and a class mapping for
'classes.Lom_Relation'. It seams castor is not able to find the
class.
Do you have such a class in your classpath or may the class be
located
in a different package?
