Adding RICHFACES to existing JSF2 project

问题

I'm trying add richfaces to my JSF 2 project using this jboss guide. I've did what they say in point 2.6, but after restart my tomcat server, HTTP Status 404 is reported.

Have I missed something??

UPDATE: When I add richfaces-components-ui-4.0.0.Final.jar and richfaces-core-impl-4.0.0.Final.jar, and restart the tomcat server, it reports:

INFO: Unsanitized stacktrace from failed start...

And now I'm not sure which libraries are neccessary for JSF2 and which for RICHFACES..

回答1:

According to readme.txt of RichFaces 4 the following JARs are required:

In addition to the RichFaces jars, a number of dependencies are required in order to properly configure the framework.

a. sac-1.3, cssparser-0.9.5 - required for components CSS work.

b. google-guava-r08 - core runtime dependency.

c. annotations.jar - from org.richfaces.cdk.

• It's optional and only needs to be added if RichFaces components will be created/accessed dynamically in your apps actions/listeners.

d. validation-api.jar and any implementation like hibernate-validators.jar

• It's optional and should be added if you using Client or Graph Validation. Should be added only if it's not provided by a server (Java EE 6 servers).

Your exception suggests that you don't have the Google Guava library.
