[castor-user] Problem unmarshalling List

[pablo fernandez]

Guys,

I have this Xml:

<hashedAddresses>
  <personAddress index='1'>
    <hashedAddress>asdfasdf</hashedAddress>
    <hashedAddress>asdfasdf</hashedAddress>
    <hashedAddress>asdfasdf</hashedAddress>
  </personAddres>
  <personAddress index='2'>
    <hashedAddress>asdfasdf</hashedAddress>
    <hashedAddress>asdfasdf</hashedAddress>
    <hashedAddress>asdfasdf</hashedAddress>
  </personAddres>
</hashedAddresses>

That I want to unmarshall in this class:


public class EmailHashEntry {

  private int index;
  private List<String> hashes;

  public EmailHashEntry() {

  }

  public void setHashes(List<String> hashes) {
    this.hashes = hashes;
  }

  public void setIndex(int index) {
    this.index = index;
  }

  public List<String> getHashes() {
    return hashes;
  }

  public int getIndex() {
    return index;
  }
}

Using this MAPPING:

<?xml version="1.0"?>
<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN" "
http://castor.org/mapping.dtd";>
<mapping>
  <class name="com.linkedin.osc.model.EmailHashEntry" >

    <map-to xml="hashedAddresses"/>

      <field name="index" >
         <bind-xml name="index" node="attribute" />
      </field>

      <field name="hashes">
        <bind-xml name="hashAddress" location="personAddresses"
node="element" />
      </field>

  </class>
</mapping>


PROBLEM:

java.lang.IllegalArgumentException: list is not a valid
FieldMappingCollectionType

I adding "collection='arraylist'" to the mapping and got a NPE.

Thanks
