How to update data from a web service

Question

Hi all,
I have a webservice that returns some data as e4x type. I
pull the data i need and put it into an object. I manipulate that
data, then I want to write it back with another webservice. I get
serialization errors when I call the update method. I must be doing
something wrong here. Can anyone help?
Webservice Methods:
<mx:operation name="FetchfrmContact" resultFormat="e4x"
result = "fetchfrmContactResultHandler()">
<mx:request/>
</mx:operation>
<mx:operation name="updatefrmContactCampaigns"
resultFormat="e4x"
result="updatefrmContactCampaignsResultHandler()">
<mx:request/>
</mx:operation>
Below is what .lastResult looks like from the fetch method of
the webservice. I update the different campaign fields by adding or
removing them in an object called contactData.
<FetchfrmContactResponse xmlns:xsd="
http://www.w3.org/2001/XMLSchema"
xmlns:soapenv="
http://schemas.xmlsoap.org/soap/envelope/"
xmlns="urn:DefaultNamespace" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance">
<FetchfrmContactReturn>
<campaignsOptedOut>
"BP - 411"
</campaignsOptedOut>
<campaignsOptedOut>
"200700 - Avnet Leads"
</campaignsOptedOut>
<campaignsOptedOut>
"200700 - BP-AdHoc"
</campaignsOptedOut>
<campaignsReceived>
"BP - 411"
</campaignsReceived>
<campaignsSubscribed>
"200700 - Avnet Leads"
</campaignsSubscribed>
<campaignsSubscribed>
"200700 - BP-AdHoc"
</campaignsSubscribed>
<campaignsSubscribed>
"200700 - BP - BCS"
</campaignsSubscribed>
<campaignsSubscribed>
"200700 - BP - Extracomm"
</campaignsSubscribed>
<campaignsSubscribed>
"200700 - BP - IBM"
</campaignsSubscribed>
<campaignsSubscribed>
"BP - 411"
</campaignsSubscribed>
<companyDocID>
"CMDPDN-65HTAK"
</companyDocID>
<companyName>
"Provena Hospitals"
</companyName>
<contactDocID>
"CTGSCG-6AHLWW"
</contactDocID>
<contactEmail>
"[email protected]"
</contactEmail>
<contactFirst>
"Steve"
</contactFirst>
<contactLast>
"Rieger"
</contactLast>
<docID xsi:nil="true"/>
<fetchBy>
"email"
</fetchBy>
<form xsi:nil="true"/>
<locationDocID/>
</FetchfrmContactReturn>
</FetchfrmContactResponse>
The fetch method returns an object of type FrmContactType and
the update method takes an object of type FrmContactType as it's
parameter
package com.psc.components
import mx.collections.ArrayCollection;
import mx.collections.XMLListCollection;
[Bindable]
public class FrmContactType
// field variables
public var contactDocID : String;
public var companyDocID : String;
public var locationDocID : String;
public var campaignsOptedOut : XMLListCollection; //
SFProfileField_70
public var campaignsReceived : XMLListCollection; //
SFProfileField_68
public var campaignsSubscribed : XMLListCollection; //
SFProfileField_69
public var contactEmail : String = "";
public var fetchBy : String;
public var docID : String;
public var form : String;
public var contactFirst : String = "";
public var contactLast : String = "";
public var companyName : String = "";
Here is the result handler of the fetch method
private function fetchfrmContactResultHandler() : void
contactData.contactFirst =
wsfrmContactLookup.FetchfrmContact.lastResult..contactFirst;
contactData.contactLast =
wsfrmContactLookup.FetchfrmContact.lastResult..contactLast;
contactData.companyName =
wsfrmContactLookup.FetchfrmContact.lastResult..companyName;
contactData.contactDocID =
wsfrmContactLookup.FetchfrmContact.lastResult..contactDocID;
if( wsfrmContactLookup.FetchfrmContact.lastResult )
contactData.campaignsReceived = new XMLListCollection(
wsfrmContactLookup.FetchfrmContact.lastResult..campaignsReceived );
contactData.campaignsSubscribed = new XMLListCollection(
wsfrmContactLookup.FetchfrmContact.lastResult..campaignsSubscribed
contactData.campaignsOptedOut = new XMLListCollection(
wsfrmContactLookup.FetchfrmContact.lastResult..campaignsOptedOut );
if( contactData.campaignsSubscribed.length > 0 )
for( var index : int = 0; index <
checkBoxSubscribed.length; index++ )
checkBoxSubscribed[index].selected = true;
if( contactData.campaignsOptedOut.length > 0 )
for( index = 0; index < checkBoxOptedOut.length; index++
checkBoxOptedOut[index].selected = true;
In my code I update the contactData object, then call the
update method passing contactData as it's parameter and it barks at
me. Any ideas why I'd be getting the error message shown below?

Hi,
just create a skeleton for the Web Service. In JDeveloper, create a new project and then use the "NEW" context menu option.
Navigate to "Business Tier" --> Web Services and select "Web Service Proxy"
In teh following, provide the WSDL reference to create the Java proxy. This gives you accss to the WS without having to parse the XML yourself
