Do not process Composite-ID classes (hbmtemplate)

Hello,

I am using hbmtemplate to generate DAOs from entities. A problem raises when I use the ANT task below: Not only entities, but also composite ids inside them are being processed.

Finally my template produces DAOs for entities AND composite ids. But DAOs for composite ids make no sense at all.

How do I set up hbmtemplate or my freemarker-template to ignore composite id classes while processing?

Code:

         <!-- Generate Daos -->
         <hbmtemplate
            filepattern="dao/{class-name}DaoImpl.java"
            templatepath="${buildconfig}"
            template="dao.ftl">
         </hbmtemplate>

in b9 the trick is to check if something is a component and then just bail out so no content is generated (and the file would not be generated)

in lateer version (svn) you can set foreach on the hbmtempalte to:

configuration - generate a single file with a $cfg variable

entity - generate a file per entity

component - generate a file per component

...and these can be comma seperated to control what you want.

Is b9 a version number?

I tried to use foreach="entity" within the hbmtemplate but it did not work. I guess I would have to use the latest svn version. But I do not like to use development releases.

Code:

                 <hbmtemplate 
                    templatepath="${templates}" 
                    template="${spring.daos.template}" 
                    destdir="${webinf}"
                    filepattern="${context-daos.xml}"
                    foreach="entity">
                 </hbmtemplate>

What about thoe other way to bail out if the current component is NOT an entity? From where do I bail out? From within the freemarker template would be too late wouldnt it? I assume the file is generated at this point already. So how do I bail out from within the hbmtemplate tag?

Thanks in advance!

do a conditional if on isComponent

Code:

<#if !c2j.isCompnent(pojo)>
 blahblah
</#if>

if the generated content is empty after a call to .trim() we don't generate a file.

Code:

[hibernatetool] Method public boolean org.hibernate.tool.hbm2x.Cfg2JavaTool.isComponent(org.hibernate.mapping.Property) threw an exception when invoked on org.hibernate.tool.hbm2x.Cfg2JavaTool@1878144
[hibernatetool] The problematic instruction:
[hibernatetool] ----------
[hibernatetool] ==> if !c2j.isComponent(pojo) [on line 1, column 1 in spring-daos.ftl]

Code:

<#if !c2j.isComponent(pojo)>.....</#if>

Throws an exception for me :(

Code:

freemarker.template.TemplateModelException: Method public boolean org.hibernate.tool.hbm2x.Cfg2JavaTool.isComponent(org.hibernate.mapping.Property) threw an exception when invoked on org.hibernate.tool.hbm2x.Cfg2JavaTool@1878144

grrrr...i suck.

!pojo.isComponent()

the c2j method is for properties.
