Problem
While deploying JSF 2.0 web application to Tomcat 6.0.26, hits the “JSP version of the container is older than 2.1” exception and failed to start the Tomcat server. But the JSP api v2.1 is included in the project class path, why the Tomcat is still saying that JSP version is older than 2.1?
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
</dependency>
Here’s the error stacks…
SEVERE: Critical error during deployment:
...
Caused by: com.sun.faces.config.ConfigurationException:
It appears the JSP version of the container is older than 2.1 and unable to
locate the EL RI expression factory, com.sun.el.ExpressionFactoryImpl.
If not using JSP or the EL RI, make sure the context initialization parameter,
com.sun.faces.expressionFactory, is properly set.
Solution
Not really sure the root cause of it, but the solution is include the el-ri.jar library
<dependency>
<groupId>com.sun.el</groupId>
<artifactId>el-ri</artifactId>
<version>1.0</version>
</dependency>
P.S This el-ri.jar is available at the default Maven central repository.
Note
The JSF 2.0 released note didn’t mention about this el-ri.jar dependency library, that’s weird.

Updated – 21-10-2010
This “el-ri.jar” is too old, it’s recommended to use the latest “el-impl-2.2.jar”, from Java.net
<dependency>
<groupId>org.glassfish.web</groupId>
<artifactId>el-impl</artifactId>
<version>2.2</version>
</dependency>
It helped a lot! Thank you!
It could be also possible, that a wrong EL-Implementation was defined inside the web.xml file.
In one case, JUEL EL was implementated, but JBOSS EL was declared. Replacing the broken definition fixed the issue.
Example for JBoss EL:
com.sun.faces.expressionFactory
org.jboss.el.ExpressionFactoryImpl
Example for JUEL EL:
com.sun.faces.expressionFactory
de.odysseus.el.ExpressionFactoryImpl
After I’ve put the el-impl 2.2 dependency I got the following error:
javax.servlet.ServletException: FacesContext must not be null
javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
root cause
java.lang.IllegalArgumentException: FacesContext must not be null
Just some update if someone get the error like me…
I get the El parsing error for JSF Table manipulation example
I solved it put I have include to jars AS suggested by mkyong
el-api-2.2.jar
el-impl-2.2.jar
jstl-impl-1.2.jar
and also one context parameter in web.xml for new EL version
com.sun.faces.expressionFactory
com.sun.el.ExpressionFactoryImpl
thanks Mkyong
for this valuable resource
Glad to know it worked for you, we all learn through sharing 🙂
“el-impl-2.2.jar” from Java.net>>> Thanks for pointing me to the right direction for a solution to this problem.
