Hi Matt,

The problem is here:

<field name="requestParam"
type="org.ifmc.arp.common.util.RequestParamEntry"
handler="org.ifmc.arp.common.util.RequestParamHandler"/>

During unmarshalling Castor will find the <request-param> element and as
it stands it's mapped to the given field descriptor above which tells it
that <request-param> is a RequestParamEntry. So Castor creates a new
RequestParamEntry object.

Then the unmarshaller recieves <request-param-entry> child element and
is unable to
find a request-param-entry field inside of the previously created
RequestParamEntry which is currently the parent object.

So you can see the dilemma.

Since your requestParam contains a collection, I think you mark it as
such you'll be ok:

<field name="requestParam"
type="org.ifmc.arp.common.util.RequestParamEntry"
handler="org.ifmc.arp.common.util.RequestParamHandler"
collection="array" container="false"/>

collection="array" should be whatever is returned by your
RequestParamHandler. So if you return an arraylist, then use
collection="arraylist".

unable to find FieldDescriptor in ClassDescriptor error

i have an object (request) that contains a hashmap (requestParam) that contains a bunch of key/value pairs which all are strings. i'd like to marshall and unmarshall this object. per a keith viscco post i did an object which wraps the hashmap and created a custom field handler for it. thanks for all the example code on the site!!! i can marshall to xml fine, but when i try to take that xml and unmarshall it to a request object i get the following error: org.xml.sax.SAXException: unable to find FieldDescriptor for 'request-param-entry' in ClassDescriptor of request-param-entry here is my xml file: <?xml version="1.0" ?> <request> <failed-attempts>0</failed-attempts> <notify>true</notify> <parent-request-id>0</parent-request-id> <request-date>2003-01-16T15:16:25.359</request-date> <request-id>0</request-id> <requestor> <user-id>10</user-id> <user-name>mgoodwin</user-name> </requestor> <requestor-id>10</requestor-id> <request-param> <request-param-entry xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="java:org.ifmc.arp.common.util.RequestParamEntry"> <key>phone</key> <value>555555555</value> </request-param-entry> <request-param-entry xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="java:org.ifmc.arp.common.util.RequestParamEntry"> <key>password</key> <value>password</value> </request-param-entry> </request-param> </request> here is the relevant parts of the mapping file: <mapping> <class name="org.ifmc.arp.bean.impl.Request" > <map-to xml="request"/> <field name="failedAttempts" type="integer" required="false" > <bind-xml name="failed-attempts" node="element" /> </field> <field name="notify" type="boolean" required="false" get-method="isNotify" > <bind-xml name="notify" node="element" /> </field> <field name="parentRequest" type="org.ifmc.arp.bean.impl.Request" required="false" > <bind-xml name="parent-request" node="element" /> </field> <field name="parentRequestId" type="integer" required="false" > <bind-xml name="parent-request-id" node="element" /> </field> <field name="requestDate" type="date" required="true" > <bind-xml name="request-date" node="element" /> </field> <field name="requestId" type="integer" required="true" > <bind-xml name="request-id" node="element" /> </field> <field name="requestor" type="org.ifmc.arp.bean.impl.User" required="true" > <bind-xml name="requestor" node="element" /> </field> <field name="requestorId" type="integer" required="true" > <bind-xml name="requestor-id" node="element"/> </field> <field name="requestParam" type="org.ifmc.arp.common.util.RequestParamEntry" handler="org.ifmc.arp.common.util.RequestParamHandler" /> </class> <class name="org.ifmc.arp.common.util.RequestParamEntry" > <map-to xml="request-param-entry" /> <field name="key" type="string" required="true" > <bind-xml name="key" node="element" /> </field> <field name="value" type="string" required="true" > <bind-xml name="value" node="element" /> </field> </class> </mapping> do i need to make a class descriptor. i'm not exactly sure how to. ----------------------------------------------------------- If you wish to unsubscribe from this mailing, send mail to minimalist@xxxxxxxxxx with a subject of: unsubscribe castor-dev

Changing methode names

Hi there, I am working on a Cobol CopyBook Parser which does the following: 1). It reads a Cobol CopyBook 2). Converts it to a XML/XSD Scheme 3). Generate JAVA classes I got this thing working now (still simple copybooks only) but I have to following "challenge". Over here we use DDIS which generates parameter names etc. for a copybook. These parameters are like this for instance: P11410-G34745. Example: a get exhange rate message of a currency (EUR) on a certain date (01-01-2003) could be something like this: <P11410> <P11410-G12345>01-01-2003</P11410-G12345> <P11410-G12346>EUR</P11410-G12346> </P11410> I created a XSD for the above stated example and Castor generates a class with getters like: setP11410G12345(String); // for the date setP11410G12346(String); // for the isocode What I want is that Castor generates class methods like setIsoCode(String) setDate(String) but it should marshall the code in <P11410> <P11410-G12345>01-01-2003</P11410-G12345> <P11410-G12346>EUR</P11410-G12346> </P11410> insteadof <Exchange-Rate> <Date>01-01-2003</DATE> <IsoCode>EUR</IsoCode> </Exchange-Rate> Is something possible? Kind regards, Arnoud Wolfard.
