[castor-dev] problem going from XML --> Java Object --> database

[Stephen Ince]

I am getting the following intermittent problems with my mappings file. I can't seem to go back and fourth between XML , java and database persistence.

 

Error:

org.exolab.castor.jdo.DataObjectAccessException: no method to set value for field: com.opendemand.jdo.ResponseHeader in class: ClassMolder com.opendemand.jdo.WebResource

 

I also see the following nested error which I think is causing it.

 

This Database operation failed : Nested error: java.sql.SQLException: Integrity constraint violation: REQUEST_HEADER_FK table: WEB_RESOURCE in statement [INSERT INTO request_header (id,name,value,web_resource_id) VALUES (66,'Pragma','no-cache',14)]

 

I have the following steps:

1) Import XML file (marshall) to a java object  (works fine)

2) Java object -> database ( big problem)

 

 

 

com.opendemand.jdo.ResponseHeader depends on com.opendemand.jdo.WebResource.

 

Mapping file:

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

<class name="com.opendemand.jdo.WebResource" auto-complete="false" identity="webResourceId" key-generator="HIGH-LOW" >

<description>Default mapping for class com.opendemand.jdo.WebResource</description>

<map-to table="web_resource" xml="web-resource"/>

<cache-type type="unlimited" />

:

<field name="responseHeaders"

type="com.opendemand.jdo.ResponseHeader" required="false"

direct="false" transient="false" collection="arraylist"

get-method="getResponseHeaders" set-method="addResponseHeader" >

<bind-xml name="response-headers" node="element" auto-naming="deriveByClass"/>

<sql many-key="web_resource_id" dirty="ignore" />

</field>

</class>

 

 

Java Code:

WebResource.java:

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

public class WebResource implements WebResourceContainer, Serializable,  Comparable, Persistent, TimeStampable,  Cloneable {

 

    public void addResponseHeader(ResponseHeader hdr  ){
        hdr.setWebResource(this);
        responseHeaders.add(hdr);
    }

}
