Re: AW: use parameter from sitemap in java transformer

[Jorg Heymans]

ztrange :)
This has worked for me exactly like this a million times before. Are you 
seeing anything in error.log?
Alternatively the parameterizable interface that Rui suggests should 
also work, although for me setup() is more clear. setup() is called on 
each pipeline component during pipeline setup.

Try putting extensive logging everywhere, i have a feeling something is 
not happening like you think it is, but can't pinpoint it (how's that 
for a useless vague statement eh :)

Thanx for your quick answer. However It didn't work. I overwrote the setup
method in my transformer like this had to catch the ParameterException
public void setup(SourceResolver resolver,Map objectModel,String src,
Parameters par)
                        throws ProcessingException, SAXException,
IOException {
if (par.isParameter("componentTag")) {
        try {
                this.COMP_TAG = par.getParameter("componentTag");
        }catch (ParameterException pe) {
                System.out.println("Failed to get parameter \"componentTag\"
from sitemap!");
        }
}
}
):, but the parameter COMP_TAG stays on the default initialization value, no
matter how I change the parameter in the sitemap.
When is the setup method called? I tried to put a system.out.println into
setup(), but it didn't even show up in the console :o

override the setup() method

    public void setup(
        SourceResolver resolver,
        Map objectModel,
        String src,
        Parameters par)
        throws ProcessingException, SAXException, IOException {
            if (par.isParameter("myparameter")) {
                this.parameter = par.getParameter("myparameter");
            }

Hi,



i’ve written a transformer in java,



<map:transformer name="addLinks"
src="de.amacont.dom.transformation.LinkTransformer"/>


which works well. Now I want to use a parameter in it, which I can set
in the sitemap, like




<map:transform type="addLinks">

   <map:parameter name="componentTag" value="span"/>

</map:transform>



I don’t know how to, though. I know who I can use such a parameter in
XSL Stylesheets, but Java? How do I instantiate them?
My transformer extends from AbstractDOMTransformer and just implements
the transform(Document) method.




Thx for your help

stefan
