Enumeration type versus WebServices

pstruhos · **Joined:** Fri Nov 21, 2003 10:23 am **Posts:** 81

I have pojo object that have property that is enumeration type. Because PersistentEnum is no longer supported by Hibernate, I must use Custom Type. But there is a problem, because Custom Type must implement UserType interface, where java specific classes are used and this results in problem transfering such class through WebServices.

How to solve this problem? Any help?

Tnx lot.

Do not let your Enum classes implement UserType, use a seperate class.

Ok, but how I will use enum type in pojo and how I will map this enum type to db?

Now I have enum type:

Code:

public class BooleanType implements UserType, MyEnum {

and in pojo I have:

Code:

    /**
     * @hibernate.property type="com.pxpfs.excom2.finance.domainmodel.BooleanType"
     */
    public BooleanType getReadOnly() {
        return readOnly;
    }

But if I create something like:

Code:

public class BooleanType implements MyEnum {

how will look snippet in pojo object?

You have two classes: MyEnum and MyEnumUserType. One is a plain Java class, using the Typesafe Enumeration design pattern and the other one is a Hibernate custom UserType that knows how to persist and load instances of MyEnum. MyEnum doesn't know anything about Hibernate.

Can you send me code fragment of pojo object that uses MyEnum and MyEnumUserType?

There are several examples on the Wiki and we don't provide handholding.

Ok, so why you reply on my question?
There is no additional information for me...
