Hi All,
I'd like to write my own generator. I have written the following generator
according to the documents on the Cocoon 2 site, by extending an example.
I can start the generator properly, but I can not pass any parameter to it.
Somehow I'd like to reach the HTTP request itself (requested URI, headers
etc.) within the generator.
public class AnyName extends AbstractGenerator
{
/**
* The only implemented method from AbstarctGenerator.
* It simply generates SAX events from a string.
*/
public void generate() throws IOException, SAXException,
ProcessingException
{
//This string will be feeded to the transformer pipeline as sax events
String xmlText = "<doc>\nMy first Cocoon 2 generator\n";
//This object will read and parse the XML content
XMLReader xmlReader = XMLReaderFactory.createXMLReader();
//super.xmlConsumer will receive the SAX events
xmlReader.setContentHandler(super.xmlConsumer);
String paramNames[] = parameters.getNames();
xmlText += "Number of parameters: " + paramNames.length + "\n";
xmlText += "Parameter names:\n";
for(int i = 0; i < paramNames.length; i++)
xmlText += paramNames[i] + "\n";
xmlText += "Source: " + source + "\n";
xmlText += "</doc>";
//Create an InputSource from the hardcoded string
InputSource src = new InputSource(new StringReader(xmlText));
//Parse the XML input and generate SAX events to the consumer
xmlReader.parse(src);
}
}
I use the following pipeline. In the generated XML I could see the
parameters, and the source, but it seems that the source is null, and no
parameters are passed to the generator.
<map:pipeline>
<map:match pattern="foo/*">
<map:act type="request">
<map:parameter name="parameters" value="true"/>
<map:generate type="ist" source="{1}"/>
<map:serialize type="xml"/>
</map:act>
</map:match>
<map:handle-errors>
<map:transform src="stylesheets/system/error2html.xsl"/>
<map:serialize status-code="500"/>
</map:handle-errors>
</map:pipeline>
How could I get the request data in the generator?
Thanks in advance!
Br,
Istvan
