Damon, I've had a StackOverflow when a class contained a getParent() method, so that when I marshalled the parent it included the child...which called getParent() to include the parent...which included the child...and so on until the stack overflowed. Default Castor marshalling uses introspection and so calls the available property getters.
I got round this by specifying the mapping file and leaving out getParent().

I did a cursory search of the archives and didn't find anything directly related to my query. That is not to say it isn't out there and I missed it, however, I am new to Castor and in need of a little assistance. I have the following binding file: <?xml version="1.0"?> <!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Ojbect Mapping DTD Version 1.0//EN" "http://castor.exolab.org/mapping.dtd";> <mapping> <class

Mapping _mapping = new Mapping(); _mapping.loadMapping(RDCCProperties.ROOT_DIR + "castorBinding.xml") public void writeTempData(OutboundJob job) { String technicianNumber = job.getTechnicianID(); System.out.println("tech id is " + technicianNumber); try { Marshaller marshaller = new Marshaller(new java.io.OutputStreamWriter(new java.io.FileOutputStream(RDCCProperties.TEMP_DATA_STORE + technicianNumber + ".xml"))); marshaller.setMapping(_mapping); marshaller.marshal(job); } catch (Exception ex) { ex.printStackTrace(); } } I will not post the code, but I have verified that all fields match correctly. I have this method to test marshalling public void writeTempData(OutboundJob job) { String technicianNumber = job.getTechnicianID(); System.out.println("tech id is " + technicianNumber); try { Marshaller marshaller = new Marshaller(new java.io.OutputStreamWriter(new java.io.FileOutputStream(RDCCProperties.TEMP_DATA_STORE + technicianNumber + ".xml"))); marshaller.setMapping(_mapping); marshaller.marshal(job); } catch (Exception ex) { ex.printStackTrace(); } } As soon as this method is executed I simply get java.lang.StackOverflowError Any thoughts?
