Castor Issue

[Venkat Pavan Kumar Bellapu Konda]

Hi,

I have query regarding Castor XML mapping.

I have a set of predefined java objects and I have an XML which I want to map to these java objects.

I came up with the mapping file and everything works great apart from the custom field handlers. The field handlers only get invoked if there is a corresponding XML element. But what if I want to default a value if the XML does not have an element?

Please help me find a solution for this problem. I am sure you might have this feature, but I am not able to achieve this.

Appreciate your help

Thanks & Regards,

Pavan

Actually, not sure myself. I definitely know how this is handled for
Java classes generated from XML schemas.

As such, can I ask you to provide me with a minimal test case, and I
will have a look.

Regards
Werner

Here is an example. Since the XML does not have created by and creation date elements. The Castor does not use the default handlers. If I added those elements to the XML then they are being used. Is there any way to default these values in the final object?

Config file

<mapping>

<description>AVQ Mapping Info</description>

<class name="com.comcast.ets.tpp.ilec.response.loader.entity.AVQResponse">

<map-to xml="AVQ_RESPONSE" ns-uri="http://www.comcast.com/ets/tpp/ilec/inbound/avq/types" />

<field name="tppInAvqhdr" type="com.comcast.ets.tpp.ilec.response.loader.entity.avq.TppInAvqhdr">

<bind-xml name="AVQHDR" node="element"/>

</field>

</class>

<class name="com.comcast.ets.tpp.ilec.response.loader.entity.avq.TppInAvqhdr">

<map-to xml="AVQHDR" ns-uri="http://www.comcast.com/ets/tpp/ilec/inbound/avq/types" />

<field name="hdrRecType">

<bind-xml name="HDR_REC_TYPE" node="element"/>

</field>

<field name="hdrType">

<bind-xml name="HDR_TYPE" node="element"/>

</field>

<field name="hdrTxnum">

<bind-xml name="HDR_TXNUM" node="element"/>

</field>

<field name="hdrTp">

<bind-xml name="HDR_TP" node="element"/>

</field>

<field name="hdrDatetime">

<bind-xml name="HDR_DATETIME" node="element"/>

</field>

<field name="createdBy" type="string" handler="com.comcast.ets.tpp.ilec.response.loader.utils.DefaultUserHandler" />

<field name="creationDate" type="string" handler="com.comcast.ets.tpp.ilec.response.loader.utils.SysdateHandler" />

</class>

Sample XML

<?xml version="1.0" encoding="UTF-8"?>

<?xml version="1.0" encoding="utf-8"?>

  <N1:AVQ_RESPONSE xmlns:N1="http://www.comcast.com/ets/tpp/ilec/inbound/avq/types">

    <N1:AVQHDR table="string">

      <N1:HDR_REC_TYPE>3</N1:HDR_REC_TYPE>

      <N1:HDR_TYPE>string</N1:HDR_TYPE>

      <N1:HDR_TXNUM>string</N1:HDR_TXNUM>

      <N1:HDR_TP>string</N1:HDR_TP>

      <N1:HDR_DATETIME>string</N1:HDR_DATETIME>

  </N1:AVQHDR>

</N1:AVQ_RESPONSE>

Okay, can you please create a new Jira issue at

http://jira.codehaus.org/browse/CASTOR

and attach source code, mapping file and XML documents. And please try
to keep things as minimal as possible.

Werner
