<br>
</div>many thanks for your suggestion. I'm coming forward and I've experimented a<br>
bit with a separate "Dynamic Web Project" in Eclipse.<br>
<br>
Note that I have moved WebContent/META-INF/yourtags.tld to WebContent/WEB-<br>
INF/yourtags.tld to be able to run it, as I have seen in several tutorials.<br>

I could run the example as standalone and I have now the Taglib example<br>
running as servlet on tomcat, but I cannot access it from inside my opencms<br>
application:<br>

Accessing in the browser <a href="http://localhost:8080/opencms/opencms/test-tag.jsp" target="_blank">http://localhost:8080/opencms/opencms/test-tag.jsp</a><br>
I'm getting this error:<br>

The absolute uri: <a href="http://localhost:8080/HelloWorldTag/WEB-INF/yourtags.tld" target="_blank">http://localhost:8080/HelloWorldTag/WEB-INF/yourtags.tld</a><br>
cannot be resolved in either web.xml or the jar files deployed with this<br>

<br>
Do you mean the Taglib has to be run as a separate servlet or do I have to<br>
integrate it inside my opencms application?<br>
<br>
