Hi -
I'm trying to compile my object which has a superclass that implements
interfaces. I've tried running both the command as well as Ant options but
the error remains the same. The structure of my hierarchy is
1. AbstractClass A implements Interface
2. Class B extends A implements Serializable
3. Both classes are in different packages.
4. I can run the compiler on the base class and it works fine. The same
works fine for the subclass if I remove the inheritance [extends] from the
subclass.
I've tried the various extension tricks mentioned on the site but get the
same stack trace. My binding.xml is as below
<?xml version="1.0" encoding="UTF-8"?>
<binding>
<!--<mapping class="com.ClassA" abstract="true"
type-name="A">
<value name="creationDate" field="creationDate" usage="required"/>
...
</mapping>-->
<include path="bindingExt.xml"/> // moved the commented code above to a
different bindingExt.xml. Doesn't work even if I remove the comments and the
<mapping name="test" // <include> tag.
class="com.vo.ClassB"
extends="com.ClassA">
<structure map-as="A"/>
<value name="name" field="name" usage="required"/>
...
</mapping>
</binding>
Here is the stack trace: Can someone point me to what am I doing wrong here.

Since I'm new to JIBX I don't have an idea what exactly is going wrong.
Another thing is that JIBX fails to find classes that are included as
dependent projects when I run the compile option.
Thanks & Regards,
