My taglib doesn't work
Hello,
I had tried to write my own taglib using the TagTransformer but it
doesn't work. I can't find some informations about it, so I had copied
the example and changed something but it doesn't work. I want to use a
tag <hello/> to print out "HELLO WORLD". My changes in detail:
1.) I had written my own class HelloWorldTag:
package foo.bar.taglib;
import org.apache.cocoon.taglib.XMLProducerTagSupport;
import org.xml.sax.SAXException;
import org.xml.sax.Attributes;
public class HelloWorldTag extends XMLProducerTagSupport {
public int doStartTag(String namespaceURI, String localName, String
qName, Attributes atts)
throws SAXException {
String hello = "HELLO WORLD";
this.xmlConsumer.characters(hello.toCharArray(), 0, hello.length());
this.getLogger().error("T E X T = " + hello);
return this.EVAL_BODY;
}
}
2.) I had created a subproject tagtest containing a xml file tagtest.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<root xmlns:test="urn:apache:taglib:hello">
<test:hello/>
</root>
3.) My sitemap looks as follow:
<?xml version="1.0" encoding="UTF-8"?>
<map:sitemap xmlns:map="http://apache.org/cocoon/sitemap/1.0">
<map:components>
<map:transformers default="tag">
<map:transformer name="tag"
src="org.apache.cocoon.transformation.TagTransformer" pool-max="64"
pool-min="0" pool-grow="2" logger="sitemap.transformer.newtag">
<transformer-hint>tag</transformer-hint>
</map:transformer>
</map:transformers>
</map:components>
<map:pipelines>
<map:pipeline>
<map:match pattern="">
<map:generate type="file" src="tagtest.xml"/>
<map:transform type="tag"/>
<map:serialize type="xml"/>
</map:match>
</map:pipeline>
</map:pipelines>
</map:sitemap>
3.) In cocoon.xconf I had registered the tag :
<taglib
class="org.apache.cocoon.components.ExtendedComponentSelector"
logger="sitemap.taglib.core" name="urn:apache:taglib:hello">
<tag class="foo.bar.taglib.HelloWorldTag"
logger="sitemap.taglib.core.source" name="hello"/>
</taglib>
4.) After calling http://localhost:8080/cocoon/tagtest the tag <hello/>
will not be replaces by "HELLO WORLD". I got the following output -
nothing parsed:
<?xml version="1.0" encoding="ISO-8859-1" ?>
- <#> <root xmlns:test="*urn:apache:taglib:hello*">
<test:hello />
</root>
What is wrong here? Thank you for your help.
Regards
Stephan
