    Hello,

    i have just implemented a very simple hello world portlet using the Plugins SDK for Liferay 6.0.1. Now i am getting this error within eclipse on my view.jsp:

    Can not find the tag library descriptor for "http://java.sun.com/portlet_2_0".

    The view.jsp looks like this:

    
<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>

<portlet:defineobjects />

This is the <b>Hello World by Yves</b>.


    If i deploy the portlet to the Liferay Portal it works fine.
    Does anyone know about this issue and can help me to solve this?

    Thank you.

    Best wishes,
    Yves

      I imported a war file which is in different folder. It is displaying an error that http://java.sun.com/portlet_2_0 Can not find the tag library descriptor for "http://java.sun.com/portlet_2_0". But that one is working in another projects. I included things in web.xml but even I am getting the same error.
      Thanks

      Hello again,

      just for anybody who wants to know how to solve this issue.
      Using 6.0.1, just create a web.xml with the necessary tld`s.

      Using 5.2.3, the portlet-containter.jar owns a META-INF where the tld is defined.
      I haven't tried this, but i think if one includes this jar-file into the eclipse java build path,
      the issue should dissappear, too.

      Best wishes,
      Yves

      Yves, you said "Using 6.0.1, just create a web.xml with the necessary tld`s."
      Can you explain it better? Thanks.

      Adding a web.xml to your WEB-INF folder with the following content should help.

      <?xml version="1.0" encoding="UTF-8"?>
      <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.5//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

      <web-app>

      <taglib>
      <taglib-uri>http://java.sun.com/portlet_2_0</taglib-uri>
      <taglib-location>/WEB-INF/tld/liferay-portlet.tld</taglib-location>
      </taglib>

      </web-app>

      Hi Marco,

      The liferay-portlet and the portlet taglib is not the same.

      If you are deploying your portlet with the Liferay deploy folder, you should not worry about this.

      In the liferay-plugin-package.properties file you can define additional dtd-s here (I've copied this from the mail portlet):

      portal-dependency-tlds=\
      c.tld

      The best example to check the deployment is the sample-jsp-portlet.
