Hello all.
I have a problem with the automatic xdoclet generation of hbm files. Xdoclet does not recognize the extra option of lazy collection property.
I need that option because the collection is very large and in some cases I only need to get the collection size (sql count() agg function).
I'm working with appfuse, spring and hibernate and I have an Ant build file that automatically generate the hbm based on Pojo's annotation and deploy the application in Tomcat, but I can't work if xdoclet dos not support the extra option.
Anybody could help me with this problem?

thanks in advance.


Posted: Tue Aug 08, 2006 12:17 am Post subject:

Firstly - this should be posted in the tools forum.
Secondly - what version of XDoclet are you using? and it is configured for H3.0, eg, setting the version attribute.
Thirdly - its a good idea to show a small sample of the hbm output and your XDoclet markup.

David:

Secondly: I try with xdoclet-1.3-SNAPSHOT (it comes with AppFuse) and with 1.2.3.
Configuration of hibernate version:
hibernate.version=3.1.3
this line is in lib.properties and it's used by ant when executes the build.xml.

Thirdly:

these are the annotations:

/**
* @author User
*
*@hibernate.class table="person"
*/
public class Person
private Set parts= new HashSet();
...

/**
* @hibernate.set table="part" cascade="save-update" lazy="extra" inverse="true"
* @hibernate.collection-key column="person_id"
* @hibernate.collection-one-to-many class="org.appfuse.model.Part" column="part_id"
*
*/

but the hbm file does not generate, because xdoclet expects the values true/false in lazy property and there are a SAXParseException when I try to generate the hbm.
I think that it's a xdoclet issue, i see the xtags.xml file and the lazy property is declared as a boolean, so xdoclet really does not have full support for hibernate 3.1.
I also see xdoclet hibernate tag reference and i don't find the extra value for lazy collection property.

am I doing something wrong?

what could i do?,
thanks for your help.

please could anybody help me with this problem, it seems that xdoclet does not recognize the extra value for lazy collection property.
lazy = "true/false/extra". Xdoclet only expects "true/false".

thanks in advance.

I had a quick look at the xdoclet 1.3 source and can confirm that at appears this level of support has not been implemented for it as yet. Its not a difficult change it I suggest you make the change to the xdoclet source and them submit it to xdoclets Jira. If you cannot so that then atleast create the Jira request. I may get around to making the changes but not until I finish an Oracle dialect for the tools reverse generator. There are other active commiters on xdoclet that may take it up for you.

ok David, thanks for your help.
