NullPointerException while integration of Richfaces 4 with JSF 2 using tomcat 6

[romyo0o]

Hello,

I just started to use Richfaces 4 with JSF 2.

- I added below jars to my project classpath:

1- richfaces-components-api-4.0.0.Final.jar

2- richfaces-components-ui-4.0.0.Final.jar

3- richfaces-core-api-4.0.0.Final.jar

4- richfaces-core-impl-4.0.0.Final.jar

- Then I tried to deploy the web application to tomcat 6, I got the following exception:

INFO: Unsanitized stacktrace from failed start...
com.sun.faces.config.ConfigurationException:

- Then I searched for the reason of java.lang.NoClassDefFoundError: com/google/common/base/Function Exception.

- I figured out that if I put google-collect-1.0-rc1.jar in my class path, will solve the problem.

- After adding the previous lib to my class path, I got NullPointerException as below :

So do I miss something in configuring  richfaces 4 ?!

[jsweene2]

You are missing one of the dependencies for Richfaces 4, the google-guava-r08 library is a runtime dependency: http://code.google.com/p/guava-libraries/downloads.

See here for more info on getting Richfaces 4 setup: http://community.jboss.org/wiki/HowToAddRichFaces4xToProjectsNotBasedOnMaven.

Thanks Justin for your reply

I've read the link that you provided above and followed the steps with adding the dependencies jars to the project class path as below:

And I've got the same NullPointerException !!

I don't know if i did something incorrect,

Waiting your reply

Thanks

[jsweene2]

That should be all you need to get started and the class com/google/common/base/Function is in the guava library. I would double check that the jars are indeed getting added to your classpath for the project.

[romyo0o]

I know Justin that com/google/common/base/Function is in the guava library, and the NullPointerException deosn't related to this library I think.

Really I don't know what shall I do ?
