Good time of day to you,
I tried this question on soap-user, but didn't get any answers, maybe you can help me..
I'm trying to modify the "messaging" example to send an object from address (from
"addressbook" example) object using bean encoding. The code is at the end of the
message.
If I just run the code I get the following exception:
java.lang.IllegalArgumentException: Body entries must implement the Serializer
interface.
at org.apache.soap.Body.marshall(Body.java:166)
at org.apache.soap.Envelope.marshall(Envelope.java:195)
at com.ml.edsi.mif.soap.test.SendMessage.main(SendMessage.java:86)
To fix it I modified the Address and PhoneNumber classes to extend BeanSerializer
which implements Serializer and should work for beans.
In this case I get the following exception:
java.lang.NullPointerException
at
org.apache.soap.encoding.soapenc.SoapEncUtils.generateStructureHeader(SoapEncUtils.java:160)
at
org.apache.soap.encoding.soapenc.SoapEncUtils.generateStructureHeader(SoapEncUtils.java:116)
at
org.apache.soap.encoding.soapenc.BeanSerializer.marshall(BeanSerializer.java:86)
at org.apache.soap.Body.marshall(Body.java:146)
at org.apache.soap.Envelope.marshall(Envelope.java:195)
at com.ml.edsi.mif.soap.test.SendMessage.main(SendMessage.java:86)
The reason it that at in the org.apache.soap.Body(145) the application sends null
instead of soap context to BodyEntry.marshal. So I fixed it by replacing
((Serializer)bodyEntry.value).marshall(actualEncStyle,
bodyEntry.type,
bodyEntry.value,
null,
//****Here is the change***
sink,
nsStack,
xjmr,
ctx);
with
((Serializer)bodyEntry.value).marshall(actualEncStyle,
bodyEntry.type,
bodyEntry.value,
ctx,
//****Here is the change***
sink,
nsStack,
xjmr,
ctx);
At this point marshaling works, but I get this strange output from the marshaler:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

<SOAP-ENV:Body>
<[Parts={}] xmlns:ns1="urn:po-processor" xsi:type="ns1:address"
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";>
<phoneNumber xsi:type="ns1:phone">
<exchange xsi:type="xsd:string">exch</exchange>
<areaCode xsi:type="xsd:int">201</areaCode>
<number xsi:type="xsd:string">671-1572</number>
</phoneNumber>
<zip xsi:type="xsd:int">10100</zip>
<streetNum xsi:type="xsd:int">95</streetNum>
<state xsi:type="xsd:string">NJ</state>
<streetName xsi:type="xsd:string">Green</streetName>
<city xsi:type="xsd:string">JCity</city>
</[Parts={}]>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
And the application fails when I try to send a message:
java.lang.NullPointerException

Am I doing something fundamentally wrong? I will appreciate any help.
Beast regards,
Stas.
