[Teneo] java.util.GregorianCalendar cannot be cast to java.util.Date [message #663555]

Dear all,

I would like to persist java.util.GregorianCalendar values in my database using Teneo and Hibernate. Is it possible?

I am getting the following error:

Is it necessary to change the following values?

* PersistenceOptions.USER_XSDDATE_TYPE
* ...

Thanks in advance,

Fernando

Hi Fer,
To store a gregorian calendar you have to make use of a specific user type. Teneo automatically does this for xsd
date/datetime. But if your model is not derived from a xsd then Teneo can't discover this, so you explicitly have to set
the user type.

You can use the user types provided by Teneo:
org.eclipse.emf.teneo.hibernate.mapping.XSDDate
org.eclipse.emf.teneo.hibernate.mapping.XSDDateTime

You can set the user type as an annotation (in the EDataType for example):
@TypeDef(name="GregDate", typeClass="org.eclipse.emf.teneo.hibernate.mapping.XSDDate")

Hello Martin,

Thank you very much for your response.

I would like to set the value from the *.persistence.xml file, I'm trying to set it as follows:


<eclass name="EngineeringAnnotationItem">
	<property name="issueDate">
	        <external> org.eclipse.emf.teneo.hibernate.mapping.XSDDate </external> 
	</property>			
</eclass>

But I getting an error.

org.eclipse.emf.teneo.annotations.xml.ParseXMLAnnotationsExc eption: Cannot handle element <external>

What would be the correct format?

Thanks in advance,

Fernando

Hello Martin,

I have modified my *.persistence.xml file as follows:

<eclass name="EngineeringAnnotationItem">
	<property name="issueDate">
		<type type="org.eclipse.emf.teneo.hibernate.mapping.XSDDate"/> 
	</property>			
</eclass>

But now I get the following error:

java.lang.ClassCastException: java.util.GregorianCalendar cannot be cast to javax.xml.datatype.XMLGregorianCalendar

What do you think?

Best Regards,

Fernando

Hi Fer,
Ha okay, the XSDDate user type provided by Teneo uses the javax.xml.datatype.XMLGregorianCalendar. So in this case you
need to create your own user type which can handle java.util.GregorianCalendar, you can use the XSDDate user type as an
example for this.

Hello Martin,

Thank you very much. I have already successfully implemented my UserType.
