Actually,
looking at the field mapping in detail ....
<field name="relationList" type="classes.Lom_Relation"
collection="array" get-method="getRelation"
set-method="setRelation">
<sql many-key="LOMID"/>
<bind-xml name="relation"/>
</field>
I think the problem might be with the collection type 'array', as the
exception seems to be showing as well:
> org.exolab.castor.mapping.MappingException: Could not find the class
> [Lclasses.Lom_Relation;
Let me have a look at this again .....

Hi,
Thanks for answering. Actually that field you mention is involved in a
1:N relation, as follows:
<class name="classes.Lom" identity="identity" key-generator="IDENTITY">
<map-to xml="lom" table="LOM"/>
<field name="identity" type="integer" get-method="getId"
set-method="setId">
<sql name="LOMID"/>
</field>
<field name="general" type="classes.Lom_General"
get-method="getGeneral" set-method="setGeneral">
<sql name="genID"/>
<bind-xml name="general"/>
</field>
<field name="lifecycle" type="classes.Lom_Lifecycle"
get-method="getLifecycle" set-method="setLifecycle">
<sql name="lifecycleID"/>
<bind-xml name="lifecycle"/>
</field>
<field name="metametadata" type="classes.Lom_Metametadata"
get-method="getMetametadata" set-method="setMetametadata">
<sql name="metametadataID"/>
<bind-xml name="metametadata"/>
</field>
<field name="technical" type="classes.Lom_Technical"
get-method="getTechnical" set-method="setTechnical">
<sql name="technicalID"/>
<bind-xml name="technical"/>
</field>
<field name="educational" type="classes.Lom_Educational"
get-method="getEducational" set-method="setEducational">
<sql name="educationalID"/>
<bind-xml name="educational"/>
</field>
<field name="rights" type="classes.Lom_Rights"
get-method="getRights" set-method="setRights">
<sql name="rightsID"/>
<bind-xml name="rights"/>
</field>
<field name="relationList" type="classes.Lom_Relation"
collection="array" get-method="getRelation" set-method="setRelation">
<sql many-key="LOMID"/>
<bind-xml name="relation"/>
</field>
<field name="annotationList" type="classes.Lom_Annotation"
collection="array" get-method="getAnnotation" set-method="setAnnotation">
<sql many-key="LOMID"/>
<bind-xml name="annotation"/>
</field>
<field name="classificationList"
type="classes.Lom_Classification" collection="array"
get-method="getClassification" set-method="setClassification">
<sql many-key="LOMID"/>
<bind-xml name="classification"/>
</field>
<field name="fileURL" type="java.lang.String"
get-method="getFileURL" set-method="setFileURL">
<sql name="fileURL"/>
</field>
</class>
Where could the problem be?
Thanks in advance

Hi,
it looks like the problem is NOT with the class mapping, but a field
mapping that actually is typed against this class. Is there such a field
mapping ?
