[castor-dev] StackOverFlow error while unmarshalling a primitive int(within a container)

Tue, 04 Nov 2003 17:39:03 -0800

Hey,
I'm having issues trying to unmarshall a primitive int within a container class.
The marhsalling works just fine, but when i try to unmarshall the xml, I get an infinite loop and eventually a StackOverFlow error.
I wrote a small test case to help describe the situation. Here it is .....

1. Source
-------------------------------------------------------------------------------------------
package castortest;

public class ContainerTestItem {
   private ContainerTestSubItem containerTestSubItem;

   public ContainerTestItem() {
       containerTestSubItem = new ContainerTestSubItem();
   }

   public ContainerTestSubItem getContainerTestSubItem() {
       return containerTestSubItem;
   }

public void setContainerTestSubItem(ContainerTestSubItem containerTestSubItem) {
this.containerTestSubItem = containerTestSubItem;
}
}
------------------------------------------------------------------------------------
package castortest;

public class ContainerTestSubItem {
   private int name;

   public int getName() {
       return name;
   }

   public void setName(int name) {
       this.name = name;
   }
}
----------------------------------------------------------------------------------
package castortest;

import castortest.ContainerTestItem;
import castortest.ContainerTestSubItem;
import org.exolab.castor.mapping.Mapping;
import org.exolab.castor.xml.Marshaller;
import org.exolab.castor.xml.Unmarshaller;
import org.xml.sax.InputSource;

import java.io.FileReader;
import java.io.FileWriter;

public class main {

public static void main(String args[]) {

Mapping mapping = new Mapping();

       try {
           // 1. Load the mapping information from the file
           mapping.loadMapping("container-test-mapping.xml");

           //create data
           ContainerTestItem cItem = new ContainerTestItem();
           ContainerTestSubItem csItem = new ContainerTestSubItem();
           csItem.setName(2);
           cItem.setContainerTestSubItem(csItem);

//marshal the data
Marshaller marshaller = new Marshaller(new FileWriter("items.xml"));
marshaller.setMapping(mapping);
marshaller.marshal(cItem);

//unmarshall data
Unmarshaller unmar = new Unmarshaller(mapping);
cItem = (ContainerTestItem) unmar.unmarshal(new InputSource(new FileReader("items.xml")));
} catch (Exception e) {
e.printStackTrace();
return;
}
}
}
------------------------------------------------------------------------------------------

2. mapping file

<?xml version="1.0" encoding="UTF-8"?>
<mapping>
<class name="castortest.ContainerTestSubItem" auto-complete="false">
<description>Default mapping for class castortest.ContainerTestSubItem</description>
<map-to xml="container-test-sub-item"/>
<field name="name" type="integer" required="false" direct="false" transient="false">
<bind-xml name="name" node="element"/>
</field>
</class>
<class name="castortest.ContainerTestItem" auto-complete="false">
<description>Default mapping for class castortest.ContainerTestItem</description>
<map-to xml="container-test-item"/>
<field name="containerTestSubItem"
type="castortest.ContainerTestSubItem" required="false"
direct="false" transient="false" container="true">
<bind-xml name="container-test-sub-item" node="element"/>
</field>
</class>
</mapping>

note: the container="true"
---------------------------------------------------------------------------------------------------------

3. Generated xml

<?xml version="1.0" encoding="UTF-8"?>
<container-test-item>
   <name>2</name>
</container-test-item>

---------------------------------------------------------------------------------------------------------


when i try and unmarshall the above file, using the main class provided, I get an infinite loop while trying to set the name on the sub item. I have tried to step through code and isolate the problem, but havent had too much luck yet.
Please look at this when you get a chance .... any help would be greatly appreciated.

Thanks
