The 2.4 schema is pickier about order than the 2.3 DOCTYPE.

Why do you have taglib declarations in your web.xml in the first place? They're rarely required.

hi, Bear Bibeault , is that any reference to show how to construct web.xml file ? thank you

by the way, what wrong in display - name ?

<servlet>
<servlet-name>TransactionReportServlet</servlet-name>
<display-name>TransactionReportServlet</display-name>
<description>Transaction Report Servlet</description>
<servlet-class>com.report.TransactionReportServlet</servlet-class>
</servlet>

and also, if we didn't put

<taglib>
<taglib-uri>/tags/struts-tiles</taglib-uri>
<taglib-location>/WEB-INF/tld/struts-tiles.tld</taglib-location>
</taglib>

it can detect tld automatically ? thank you again

The Servlet Specification is the best source for such information.

And yes, the container will automatically find TLD files that pput into the correct locations. There is rearely a need to declare TLDs in the web.xml.

bear, i meant on the reference to create web.xml file , where we can reference it ?

i have download the servlet spec , it actually servlet API

[Bear Bibeault]

Chapter 13 of the Servlet Specification has everything you need to know.

[Nakata kokuyo]

bear, forgive my stupidness ...

i just go to the link here and get download, it just give me API

Servlets 2.4 Specification: http://www.jcp.org/aboutJava/communityprocess/final/jsr154/


and where is the explanation as you mentioned on chapter 13 ....
mind to provide me the reference link that you mentioning ?

sorry for make trouble

[Bear Bibeault]

Are you downloading the PDF or the zip file? I just downloaded it and the PDF is the specification.

[Nakata kokuyo]

sorry , bear , i thought the html and pdf are same ...i have it now ...thanks for guidance

Really? I was led to believe that it was LESS picky - ie order was not important any more. You can mix your "servlet" and "servlet-mapping" to your hearts content.

The change that happened between 2.3 and 2.4, is that taglib entries need to be nested in a <jsp-config> section, rather than at the root level where they were before.

<jsp-config>
  <taglib>
    <taglib-uri>/tags/struts-tiles</taglib-uri>
    <taglib-location>/WEB-INF/tld/struts-tiles.tld</taglib-location>
  </taglib>
</jsp-config>

However as Bear has said, you shouldn't need that taglib entry in web.xml any more. The struts taglibs define "standard urls" that you can use to import them now:
<%@ taglib prefix="tiles" uri="http://struts.apache.org/tags-tiles"%>
