I have just had this same problem of serializing/deserializing ArrayLists.
Amazingly after searching all through the lists and surfing the web, it
seemed like nobody had done it. I know that in Axis release it looks
possible, but for the moment I am tied into SOAP 2.2 so this isn't an
option.
In the end I wrote the serializer/deserializer myself, - I'll paste java
code in below. Note that my class ObjectList extends ArrayList, so for a
pure serializer of ArrayList just replace all references of ObjectList with
ArrayList and it should work fine.
cheers, Joe.
public class ObjectListSerializer implements Serializer, Deserializer {
public void marshall(String inScopeEncStyle, Class javaType, Object src,
Object context, Writer sink, NSStack nsStack,
XMLJavaMappingRegistry xjmr, SOAPContext ctx)
throws IllegalArgumentException, IOException {
nsStack.pushScope();
if ((src != null) &&
!(src instanceof ObjectList)) {
throw new IllegalArgumentException("Tried to pass a '" +
src.getClass().toString() + "' to
ObjectListSerializer");
}
Iterator it;
ObjectList objList = (ObjectList)src;
it = objList.iterator();
if (src == null) {
SoapEncUtils.generateNullStructure(inScopeEncStyle,javaType,context,sink,
nsStack,xjmr);
}
else {
SoapEncUtils.generateStructureHeader(inScopeEncStyle,javaType,context,
sink,nsStack,xjmr);
sink.write(StringUtils.lineSeparator);
for (Iterator i = it; i.hasNext(); ) {
nsStack.pushScope();
Object value = i.next();
if (value == null) {
SoapEncUtils.generateNullStructure(inScopeEncStyle,
Object.class,
"item", sink, nsStack, xjmr);
}
else {
Class actualComponentType = value.getClass();
xjmr.marshall(inScopeEncStyle, actualComponentType, value,
"item",
sink, nsStack, ctx);
}
sink.write(StringUtils.lineSeparator);
nsStack.popScope();
}
sink.write("</" + context + '>');
}
nsStack.popScope();
}
public Bean unmarshall(String inScopeEncStyle, QName elementType, Node
src,
XMLJavaMappingRegistry xjmr, SOAPContext ctx)
throws IllegalArgumentException {
Element root = (Element)src;
if (SoapEncUtils.isNull(root)) {
return new Bean(ObjectList.class, null);
}
ObjectList objList = new ObjectList();
Element tempEl = DOMUtils.getFirstChildElement(root);
while (tempEl != null) {
String declEncStyle =
DOMUtils.getAttributeNS(tempEl,Constants.NS_URI_SOAP_ENV,
Constants.ATTR_ENCODING_STYLE);
String actualEncStyle = declEncStyle != null
?
declEncStyle
:
inScopeEncStyle;
QName declItemType = SoapEncUtils.getTypeQName(tempEl);
QName actualItemType = declItemType;
Bean itemBean = xjmr.unmarshall(actualEncStyle,
actualItemType, tempEl, ctx);
objList.add(itemBean.value);
tempEl = DOMUtils.getNextSiblingElement(tempEl);
}
return new Bean(ObjectList.class, objList);
}
}
// end of class
