[Middlegen-user] Java Plugin / JavaClass.vm

[Mario Laureti]

Hello,

I use Middlegen to generate xml file for hibernate out of a database schema.
I would also like to generate Java source class with setters and getters for every database table from the database schema.

The following is how I am doing this:

I am using a java plug in.
I wrote a small template.

Is this the right way to do this?

If yes, here is my problem:

Only the context objects $table and $tables are available. It would be nice to have
a $javaTable in the context to know which Java types to use to generate the Java class.

For now I am hard coding this information in the template and I do not feel that it is the right thing to do...

Can any one guide me in the right direction? I have attached the template I started.

Thanks

Hi Mario,

I think with the Java plugin you can use something like
${column.javaType} to get the preferred Java type for the current DB
column. Have a look at the source of middlegen/javax/JavaColumn.java and
all its getter methods.

Use the hbm2java tool from Hibernate. You need hibernate-tools.jar +
dependencies. In the Middlegen sample we use this task:

<target name="hbm2java" depends="middlegen" description="...">
<taskdef
name="hbm2java"
classname="net.sf.hibernate.tool.hbm2java.Hbm2JavaTask"
classpathref="lib.class.path"
/>

<hbm2java output="${build.gen-src.dir}">
<fileset dir="${build.gen-src.dir}">
<include name="**/*.hbm.xml"/>
</fileset>
</hbm2java>
</target>

Cheers
