I have a web service using JBoss 4.0.2. I am generating the WSDL and jax-rpc
mapping file using wscompile in rpc/literal mode. I am having problems on the
server with the deserialization of objects that contain arrays of Java Strings.
The SOAP message that is being generated by the client seems to use SOAP
encoding for the arrays, which it shouldn't be. When the server tries to
deserialize the encoded object, the deserialization fails.
The error that is thrown is a SAXException with the following message:
"SimpleDeserializer encountered a child element, which is NOT expected, in
something it was trying to deserialize." The element that it is encountering
is the < item > tag around the array elements.
This seems really basic, but I have googled and have not found anything that
solves my problem. Please help! I'm stumped.
The Java object that is causing problems:
| public final class DocumentBean {
| private String [] vals;
| public DocumentBean() {}
| public DocumentBean(String [] vals) { this.vals = vals; }
| public String [] getVals() { return vals; }
| public void setVals(String [] vals) { this.vals = vals; }
| }
|
My wscompile ant task:
| <wscompile
| fork="true"
| keep="false"
| verbose="true"
| base="${tms-build.dir}/classes"
| classpath="${wscompile.classpath}"
| server="true"
| mapping="${tms-build.dir}/jaxrpc-mapping.xml"
| features="rpcliteral,wsi"
| config="${tms-resources.dir}/tws/config.xml">
| <classpath>
| <path refid="wscompile.classpath" />
| </classpath>
| </wscompile>
|
The WSDL:
| <schema targetNamespace="http://document.tws.mycompany.com";
| xmlns:tns="http://document.tws.mycompany.com";
| xmlns:soap11-enc="http://schemas.xmlsoap.org/soap/encoding/";
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
| xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/";
| xmlns="http://www.w3.org/2001/XMLSchema";>
| <import namespace="http://document.enterprise.mycompany.com"/>
| <import namespace="http://tws.mycompany.com/types"/>
| <complexType name="DocumentBean">
| <sequence>
| <element name="vals" type="string" nillable="true" minOccurs="0"
maxOccurs="unbounded"/>
| </sequence>
| </complexType>
| </schema>
|
The JAX-RPC mapping:
| <java-type>com.mycompany.tws.document.DocumentBean</java-type>
| <root-type-qname
xmlns:typeNS="http://document.tws.mycompany.com";>typeNS:DocumentBean</root-type-qname>
| <qname-scope>complexType</qname-scope>
| <variable-mapping>
| <java-variable-name>vals</java-variable-name>
| <xml-element-name>vals</xml-element-name>
| </variable-mapping>
| </java-xml-type-mapping>
|
The SOAP message generated by the client:
| <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
| xmlns:xsd="http://www.w3.org/2001/XMLSchema";
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
| <soapenv:Body>
| <storeDocument xmlns="http://tws.mycompany.com";>
| <DocumentBean_1 xmlns="">
| <vals><item>phoebe</item></vals>
| </DocumentBean_1>
| </storeDocument>
| </soapenv:Body>
| </soapenv:Envelope>
|
