Hi, I have a very simple class as follows:

public class MyClass implements Map<String, Object> {

private int mId;

public ABID getUid()
{
return mId;
}

public void setUid(ABID id)
{
mId = id;
}
}

Okay, I know it's weird to implement Map interface, I'm dealing with lots of legacy code(this is a simplified class) and I can't change them.

mapping file as follows:
<hibernate-mapping package="com.apldbio.sds.platform.core.security">
<class name="User" table="user" lazy="false">
<id column="id" name="id">
<generator lass="native"/>
</id>
</class>
</hibernate-mapping>

I can successfully create schema using SchemaExport, however when I try to call update using spring


getHibernateTemplate().saveOrUpdate(user);
The following exceptions thrown:


org.springframework.orm.hibernate3.HibernateSystemException: could not determine type of dynamic entity; nested exception is org.hibernate.HibernateException: could not determine type of dynamic entity
Caused by: org.hibernate.HibernateException: could not determine type of dynamic entity
at org.hibernate.impl.SessionImpl.guessEntityName(SessionImpl.java:1797)
at org.hibernate.impl.SessionImpl.getEntityPersister(SessionImpl.java:1365)
at org.hibernate.engine.ForeignKeys.isTransient(ForeignKeys.java:203)


i noticed that if I remove "implements Map" from User class, everything will be fine.

But the question is that I'm using "property" access mode and all hibernate should care about is getters and setters, where is that exception coming from?

Anybody has experienced this before? Any help is appreciated.

Sorry my mistake, typo

class name is User

public class User implements Map<......

It was my typo writing this post

This is the correct User class

public class User implements Map<String, Object> {

private int id;

public ABID getId()
{
return id;
}

public void setId(ABID id)
{
this.id = id;
}
}

public class User implements Map<String, Object> {

private int id;

public ABID getId()
{
return id;
}

public void setId(int id)
{
this.id = id;
}
}

I encountered this same problem. The issue is that Hibernate is automatically trying to use "dynamic entity mode" because your class implements Map. Hibernate's logic goes like this...



The solution I used was to set a Configuration level Interceptor (that extends EmptyInterceptor) to check for my special case:



This completely solved the problem!

Here's a link to the relevant Hibernate documentation:

Hope this helps!
