Subject AW: AW: AW: use parameter from sitemap in java transformer
Date Wed, 21 Jan 2004 20:46:13 GMT
Hi again,

Below you can see what's in my sitemap an in the transformer currently. The
transformer is still working fine, the parameter not. With some system.out's
I've found out, that it doesn't seem to go into the if-loop in setup(). When
I try a system.out.println(par.toString()) it doesn't give me anything, so
it seems to me the parameter isn't passed to the setup method. 
Anything I need to specify in the sitemap perhaps to make my transformer
work with parameters?

Oh, and thanks a lot for your help so far ;)
stefan

 
<map:transformer name="addLinks"
src="de.amacont.dom.transformation.LinkTransformer"/>
...
...
<map:transform type="addLinks">
	<map:parameter name="componentTag" value="comp"/>
</map:transform>

-----------------------

public class LinkTransformer extends AbstractDOMTransformer {
  ...
  private String COMP_TAG = "span";
  ...

public void setup(...)throws ProcessingException, SAXException, IOException{

	if (par.isParameter("componentTag")) {
		try {
			this.COMP_TAG = par.getParameter("componentTag");
		}
		catch (ParameterException pe) {...}
	}
}

public Document transform(Document docu) { .....}
