I try to use custom generation with ant :

<target name="generation_custom">
<hibernatetool>
<configuration configurationfile="${generation.fichier.cfg}" >
<fileset dir="${generation.output.dir.hbm}" id="id">
<include name="**/*.hbm.xml"/>
</fileset>
</configuration>
<hbmtemplate template="${generation.templates.custom.perso1}"
destdir="${generation.output.dir.custom}"
filepattern="{package-name}/{class-name}Test.java"/>
</hibernatetool>
</target>

All my variables seem to be ok but i've got this error :

BUILD FAILED
D:\travail\eclipse\workspace\Generation\generation\GenerationHibernate.xml:104:org.hibernate.tool.hbm2x.ExporterException: Error while processing template templates/custom/perso1.vm

What can i do ?
Thanks

I find the mistake : the generator don't find my VM.
in hibernatetool target,
fileset dir=??
destdir=??
templatepath=??
etc ...
seem to search from the current folder
but
<hbmtemplate template=??
seems to search from the project root.

Where can i find the meta model. for custom templates ?
Thks

can you elaborate on meta model? $cfg should give the configuration object.

run ant with -debug or -verbose to get more info (but be prepared to see how *bad* velocity is when it comes to exception handling)

I create my own vm (copy of daohome.vm).
I try to launch it but i obtained this error :

BUILD FAILED
C:\projets\workspace\Generation\generation\GenerationHibernate.xml:166: org.hibernate.tool.hbm2x.ExporterException:
MethodInvocationException while processing template generation/templates/custom/idao.vm.
Invocation of method 'getJavaTypeName' in class org.hibernate.tool.hbm2x.Cfg2JavaTool threw exception class java.lang.NullPointerException : null

Total time: 4 seconds

Have you an idea ?
THKX

yes - getJavaTypeName is called with something bad, like a null.

/max

> yes - getJavaTypeName is called with something bad, like a null.
> max

exactly , it's the same code that in "daohome.vm" :
$c2j.getJavaTypeName($clazz.identifierProperty)

i don't understand why this line work in "daohome.vm"
but not in my own template ... ???

can it be that you class does not have an identifierproperty ?

In fact, i want to test the custom generation.
1 - i generated some hbm from hibernate ant tools.
<target name="generation_hbm" description="generation des fichiers hbm">
<hibernatetool>
<jdbcconfiguration revengfile="${generation.reveng.cfg}"
configurationfile="${generation.fichier.cfg}"/>
<hbm2hbmxml destdir="${generation.output.persistance.dir.hbm}" />
</hibernatetool>
</target>

2 - i launched the generation of dao of Hibernate Tools :
<target name="generation_dao" description="generation des dao">
<hibernatetool>
<configuration configurationfile="${generation.fichier.cfg}" >
<fileset dir="${generation.output.persistance.dir.hbm}" id="id">
<include name="**/*.hbm.xml"/>
</fileset>
</configuration>
<hbm2dao destdir="${generation.output.persistance.dir.dao}" templatepath="${generation.templates.dir}"/>
</hibernatetool>
</target>

3 - With an exact copy of "daohome.vm", i execute the task below :
<target name="generation_interface_dao" description="generation des interfaces des dao">
<hibernatetool>
<configuration configurationfile="${generation.fichier.cfg}" >
<fileset dir="${generation.output.persistance.dir.hbm}" id="id">
<include name="**/*.hbm.xml"/>
</fileset>
</configuration>
<hbmtemplate
destdir="${generation.output.persistance.dir.idao}"
template="${generation.templates.idao}"
filepattern="${generation.output.persistance.package.idao}/I{class-name}.java"/>
</hibernatetool>
</target>
------------------------------------------------------------------------
The result is :
- i have ann error other $c2j.getJavaTypeName($clazz.identifierProperty)
- if i delete theses lines, i get as one file for an hbm plus an other file is the hbm have a complex primary key (like hbm2java).

so we might have a bug with dao generation when you have composite keys. put it in jira.
