Summary: 0001532: CMP java.util.Date vs java.sql.Date cast exception
Description: (rep by Andrew Barton)


For reference, I have attached CachedImage.ejb where the ejbSelect
query in question is defined. I have also attached
CachedImageBean.java with my debug code attached.

The schema for the table in question is listed at the bottom of this
message. You will notice I am using a mysql 'datetime' data type for
the modified date.

The problem method is:
public Date ejbHomeGetModifiedDate(Integer key) {
System.out.println("CachedImageBean.ejbHomeGetModifiedDate() -
key: " + key);
try{
System.out.println("CachedImageBean.ejbHomeGetModifiedDate
(): " + ejbSelectModifiedDate(key));
return new Date();
}
catch (FinderException e){
return null;
}
}

public abstract Date ejbSelectModifiedDate(Integer id) throws
FinderException;

When the return type for ejbSelectModifiedDate is defined as a
java.util.Date, I get the following exception:

This was the previous state. When I define the return type as
java.sql.Date as in:

public abstract java.sql.Date ejbSelectModifiedDate(Integer id)
throws FinderException;

I don't get the class cast exception, but I also don't get the data I
expect. I get null instead. The debugging output returned is:

CachedImageBean.ejbHomeGetModifiedDate() - key: 1
CachedImageBean.ejbHomeGetModifiedDate(): null

So, for pk_blob_id = 1, the returned value is null. Below, you will
see that I do have a modified date in they table for pk_blob_id = 1.

I reiterate that using a return type of java.util.Date did work in
Resin-ee-3.0.7 and versions prior to that. And ejbSelectModifiedData
did properly return datetime data.

Please let me know if there is anything I can do or information I can
provide to help resolve this issue.
