Question

I have developed a JSF 2.0/Primefaces 3.2 web application running on an amazon cloud instance.
I have been having recently lot of “NoClassDefFoundError” and don’t know where to start digging. I initially thought that it has to with the Classloader but after we redeploy the application on the next day the exception disappeared.

Here are the list of jsf2.0 maven dependencies I have:

<dependecy>
      <groupId>com.sun.faces</groupId> 
      <artifactId>jsf-api</artifactId> 
      <version>2.1.3</version>
</dependency>
<dependency>
            <groupId>com.sun.faces</groupId>
            <artifactId>jsf-impl</artifactId>
            <version>2.1.3</version>
 </dependency> 
 <dependency>
            <groupId>javax.el</groupId>
            <artifactId>el-api</artifactId>
            <version>2.2</version>
            <scope>provided</scope>
 </dependency> 

Here is the exception I recently got:

Any help on this will be appreciated.

Answer 1

After some research I believe this is a bug in Primefaces 3.2 but not sure. So I upgraded to 3.3.1 and upgraded also my mojarra to 2.1.14. I am not having this issue currently.
