JSF welcome file is not recognized [duplicate]

问题

This question already has an answer here:

Set default home page via <welcome-file> in JSF project 3 answers

Accessing

http://localhost:8080/basicSetup/faces/index.xhtml

works, with the output of :

Hello World ! Albert Kam

but accessing

http://localhost:8080/basicSetup

shows

Hello World ! #{myBean.value}

meaning that the welcome file is not rendered as a JSF file

I would like http://localhost:8080/basicSetup to have the same effect as accessing http://localhost:8080/basicSetup/faces/index.xhtml.

Please share your thoughts

jetty-maven-plugin:8.0.3.v20111011:run + jdk 7 + eclipse indigo

Here is my web.xml file :

<?xml version="1.0" encoding="UTF-8"?>

and this is the jetty maven plugin output :

回答1:

The <welcome-file> is supposed represent the file name of the file which is default to be loaded whenever a folder is been requested.

<welcome-file>index.xhtml</welcome-file>

If you're using JSF 2.x, then I suggest to replace /faces/* URL pattern by *.xhtml, then the above will work and you do not need to fiddle with /faces paths in URLs anymore. Or, if you're using JSF 1.x, then I suggest to replace the /faces/* URL pattern by *.jsf and provide an empty index.jsf file next to index.xhtml in the folder to fool the container that the file really exist.
