My question is this - why is UnknownTypeHandler being called at all? iBATIS only calls this when it does not find a registered type handler. My guess is that you're not declaring the type handler properly.
Could it have something to do with my enums being declared in interfaces? That's the only difference I see between my setup and what others claim are working.

My enums are enclosed within another class, not external. As an example:
Are you using iBATIS 2.2 or below? As far as I can tell the problem was introduced in 2.2.
Tom public class DocumentStore extends DomainObject { public static enum MsgType { REQUEST, CONFIRM }
The TypeHandler declaration looks like the following: <typeHandler javaType= "com.sybase.cosmos.domain.DocumentStore$MsgType" callback="com.sybase.cosmos.dao.impl.ibatis.extentions.DocMsgTypeTypeHandlerCallback " />
I'm using Enums without difficulty. I've implemented a TypeHandlerCallback to accommodate the set and get in the following manner:
Are your enums enclosed within another class or external? My enums are enclosed within classes and iBATIS is looking for a type handler for the enclosing class on insert/update instead of the enum. Using externally declared enums w/the same type handler works fine.

Hi All,
I'm having a problem with Java 5 Enums and iBATIS
TypeHandlerCallbacks. I've read the wiki article and it doesn't help
with my particular issue. Retrieving objects is working fine but
inserting/updating them is throwing this NPE:
java.lang.NullPointerException

Here's my basic setup:
public interface Tenant {
public enum Type { FOO, BAR }
public Type getType();
public void setType(Type type);
...
}
public class TenantImpl implements Tenant {
private Type type;
public Type getType() { return type; }
public void setType(Type type) { this.type = type; }
...
}
My type handler for Tenant$Type looks a lot like the examples in the
wiki article. The types are mapped in my SqlMapConfig:
callback="com.utilivisor.dao.ibatis.TenantTypeEnumTypeHandler "/>
I'm messing around with UnknownTypeHandler.setParameter() and am very
confused. I checked the incoming value of parameter.getClass() and
it is correct, i.e., foo.bar.Tenant$Type. usingJavaPre5 is set
(Which is confusing by itself because I am using Java5) so
getBaseClass() is called and the new searchClass is foo.bar.Tenant.
I do not have or want a type handler for foo.bar.Tenant. Can anyone
help?
