Maven Dependency for Spring and Portlet tags

Question

I have this following problem in Netbeans IDE - when I create a JSP file and put these two taglibs inside

<%@taglib prefix="portlet" uri="http://java.sun.com/portlet_2_0" %> 
<%@taglib prefix="form" uri="http://www.springframework.org/tags/form"%>

then I get error The absolute uri ... cannot be resolved. So I am wondering where could be the problem?Application is working correctly when is deployed to AS but I would like to enjoy things like autocompletion during development. My pom.xml looks like this - PasteBin.

I suppose I have all the necessary JARs on classpath so how can I make NetBeans to recognize those tags?

Have you found the way how to fix it? – Smallscale

I am afraid I didn't - but this is year ago and I am doing something else right now so I don't really remember :) – Sorilda

Answer 1

To fix the portlet TLD problem add this to your POM

<dependency>
        <groupId>javax.portlet</groupId>
        <artifactId>portlet-api</artifactId>
        <version>2.0</version>
        <scope>provided</scope>
</dependency>

The scope of provided is important - bear in mind you just want this to be included for validating in your IDE. The portlet TLD will be provided by whichever JSR-286 implementation you are deploying to e.g. Liferay, uPortal etc.

NB this worked for me in Eclipse, I presume it will also do the trick in NetBeans.

It is not working for me, I have this dependency in my project since beginning. – Sorilda

Answer 2

To use sprint tags it enough to declare one spring dependency

   <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc-portlet</artifactId>
        <version>3.0.6.RELEASE</version>
    </dependency>

Spring downloads other dependencies automatically. All dependency list for spring portlet you can see here

With portlet tags a little more complicated, I still can't find dependency for portlet taglib and I always copy portlet_2_0.tld to my WEB-INF/tld folder, if you find this dependency let me know. Thanks.

I already have this dependency in my pom.xml. So I suspect it is going to be Netbeans related problem. – Sorilda

Does NetBEans have any way of turning off jsp validations? Eclipse has that....turning off validations may help make the error go away – Palpitant

Yes, when I turned it off, the error disappears. But the think is that I would like to use to autocomplete feature which is not working now. – Sorilda
