scale Image : add paths parameters in the response ?

[Eric DE MAULDE]

Hi,

I call a Java Class at first into the simple-method "updateProduct" (ProductServices.xml).
This Class scales Images from the the detail Image and write related files for small, medium and large images.
So into product content form, I don't upload image and don't type image path for small, medium and large image text area.

I have to give theses 3 new images paths from my class to the simple-method.

<simple-method method-name="updateProduct" short-description="Update an Product">
        <call-class-method class-name="org.ofbiz.image.ImageTransform" method-name="scaleImageInAllSize" ret-field-name="result">
            <field field-name="parameters" type="javolution.util.FastMap"/>
        </call-class-method>
        <if-compare field="result" operator="equals" value="success">
...

How can I do this ? (In order to save new images paths to the product content)
I can't find line uses parameter "smallImageUrl", "mediumImageUrl", "largeImageUrl" ?

Thanks
