[Andromda-user] [Hibernate cartridge] [updates on a CLOB that was only read]

[roos (A. F. <fo...@an...>]

I know that this is an old thread, but I had the problem with update-on-read for Entities holding a clob type,too.

Obfuscator's recommendation works here.

This is what I do:

in mda/src/main/config/mappings, I created a file "HibernateExtensionMappings.xml" with the following content:


<?xml version="1.0" encoding="ISO-8859-1" ?> 
<!-- 
&nbsp;Fixes/extends original AndroMDA Hibernate Mappings, which you find in HibernateTypeMappings.xml
--> 
<mappings name="HibernateExtension">
&nbsp; &nbsp;<extends>Hibernate</extends> 
&nbsp; &nbsp; <mapping> 
&nbsp; &nbsp; &nbsp; &nbsp; <from>datatype&#58;&#58;Clob</from>
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;<!-- Map to text, as the HibernateStringClobType causes an update after read 
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; &nbsp;if the attribute is NULL 
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; See http&#58;//galaxy.andromda.org/forum/viewtopic.php?t=4583 --> 
&nbsp; &nbsp; &nbsp; &nbsp; <!--to>org.andromda.persistence.hibernate.usertypes.HibernateStringClobType</to--> 
&nbsp; &nbsp; &nbsp; &nbsp; <to>text</to> 
&nbsp; &nbsp; </mapping> 
</mappings>



And in mda/src/main/config/andromda.xml, change to:

&nbsp; &nbsp; &nbsp; &nbsp; <property name="hibernateTypeMappingsUri">file&#58;$&#123;conf.dir&#125;/mappings/HibernateExtensionMappings.xml</property>



With this, the update-on-read problem is fixed here.
Tested with AndroMDA 3.2
