Hi,
I have specifically used Java 5 generics so that XFire would automatically
bind to typed collections, as has been specificed in the user guide and the
mailing list. But I have done that and Xfire is still blowing up (see error
stack below). My versions are xfire 1.2.3 and Spring 2.0
This is My service interface:
public Collection<Service> findServicesByCriteria(Collection<Criterion>
criteria) throws InvalidSearchCriteriaException ;
In turn, Service object have properties some of which are typed collections,
and similarly with Criterion object. Anyway, Xfire doesn't seem to notice
that the collections are strongly typed using java 5 generics. Here is the
Criterion definition:
import java.util.Arrays;
import java.util.Collection;
public class Criterion {
Collection<String> relations = Arrays.asList(new String[] { "eq", "gt",
"ge", "ls", "le" });
String property;
String relation;
String value;
/**
* E.g. new Criterion("name","eq","Billy Bob");
*
* @param property
* @param relation
* @param value
*/
public Criterion(String property, String relation, String value) {
super();
if (!relations.contains(relation)) {
throw new RuntimeException("Invalid relation");
}
this.relation = relation;
this.property = property;
this.value = value;
}
public String getProperty() {
return property;
}
public String getRelation() {
return relation;
}
public Collection<String> getRelations() {
return relations;
}
public String getValue() {
return value;
}
}

Error stack:
This is the exact error message when I try to deploy xfire running in
spring:
