eclipse web.xml jsp配置

Question

In an Eclipse JEE project with the Dynamic Web Module 3.0 facet enabled, I am developping a webapp fragment which consists in Java classes, JSP and other pages, which will then be deployed in a WAR. In this WAR's web.xml there's the following:

<jsp-config>
    <taglib>
        <taglib-uri>/tags/struts-tiles</taglib-uri>
        <taglib-location>/WEB-INF/struts-tiles.tld</taglib-location>
    </taglib>
    [same for other taglibs, JSTL core etc.]
</jsp-config>

Which forces me to have at the beginning of my JSPs:

<%@ taglib uri="/tags/struts-tiles" prefix="tiles"%>

But then, how do I tell Eclipse to take this jsp config into account? Right now it simply looks in the classpath, finds into standard.jar and struts.jar the tlds and sees the <uri> is wrong (for struts-tiles for example it's http://jakarta.apache.org/struts/tags-tiles and not /tags/struts-tiles ), and then the JSP parser Can not find the tag library descriptor for... .

If I paste the web.xml in my project's WEB-INF folder it seems to be ignored.

Answer 1

Did you consider using web fragments (deployment descriptor fragments), which allow you to write modular "chunks" of web.xml configuration which will then can be combined by the container during development to form the entire application.

Requirements :

1) Each fragment must reside in its own JAR (typically along side the classes being configured that make up the application) inside the META-INF/web-fragment.xml file . (at most one!)

2) The JAR file must be deployed to /WEB-INF/lib/ directory of the Web application.
