seam-gen: HowTo use own annotations

minjaman Sep 2, 2009 2:16 PM

Hello,

I found the freemarker templates for seam-gen. I guess seam-gen can only respect information which is included in the hibernate metamodel for properties Value.

I like to modify the templates to respect my own annotations.

For example:
I like to create an own annotation @ReadOnly which will not editable.

@ReadOnly
String getName() {
...
}

Have anyone a hint for me or the confirmation that currently it is not possible.

Regards
Alexander

Yes, it is possible, I have done it.
You have to create your own utility class to process you annotations.

Normally, only one utility class is included in the generation process:

<property key="hibernatetool.util.toolclass" value="org.jboss.seam.tool.Util" />

you can add your custom one like this:

<property key="hibernatetool.myextension.toolclass" value="domain.mycompany.MyUtilClass" />

After that is only a matter of using reflection inside your utility class to process your custom annotations (and of course calling your utility class from your custom freemarker (ftl) templates).

Take a look at seam-gen ant scripts look for the place where the hibernate task is called.

Thanks for your reply.

A little bit more could be helpful.

I Know to analyse existing annotations with an own utility.
I know to modify
I know to set hibernatetool.myextension.toolclass

I don't know to place my own utility inside of editproperty.xhtml.ftl and which arguments are possible for my utility.

I fear that i have to analyse seam-gen from scratch.
