The default extension for JSF facelet files is .xhtml, which looks so out-of-date these days. I wanted to change the extension from .xhtml to .html, to make it look more modern, even though I still use JSF xhtml in reality. This didn't work ( web.xml ):
<servlet-mapping> <servlet-name>Faces Ser...Using the servlet-mapping config without the context-param works, given that the actual file extensions are still .xhtml . But the caveat is, if you request the .xhtml file directly, it will be sent to the browser unprocessed. This worked:
<servlet-mapping> <servlet-name>Faces Ser...I'm using myfaces 2.1.11.

It's normal practice to import types from an external xsd file in WSDL like this:
<wsdl:types> <xsd:schema xmlns:xsd="htt...When you use <dynamic-wsdl> and have Commons XMLSchema on the class path, Spring-WS inlines the xsd in the wsdl. But that doesn't happen when you use <static-wsdl> . You can define a SimpleXsdSchema bean to expose the xsd:

The default servlet for Tomcat is declared in $CATALINA_HOME/conf/web.xml :
<servlet> <servlet-name>default</servle...Therefore, static content is rendered by the default configuration unless you override it with your own definitions. If you want to allow directory listing, just change the listing parameter to true :
<init-param> <param-name>listings</para...Change the welcome-file-list to display a default page in lieu of a directory listing:
<welcome-file-list> <welcome-file>home.xhtml</...Welcome pages are defined at the Web application level.

In the simple taglib example , I used a tag handler class to implement a taglib. This is an example to implement a taglib with a UI component. The purpose is to use a custom tag to split a string and print each part in a separate paragraph, i.e., print
<p>john</p> <p>steve</p> <p>mike</p>with custom tag <my:foreach> :
<my:foreach var="who" value="john steve mike"> ...These are the files: pom.xml
