Unable to start the Tomcat server. Compiled using Java 1.7. Using JSF 2.0. Gives UnsupportedClassVersionError: com/sun/faces/config/FacesInitializer
I have java web application which was working earlier. I upgraded it to JDK 8, and compiled the code with JDK 1.7 compliance setting. I am however getting the below error when I start the server. I actually removed all references to JDK 8 and using JDK 7, still I get the below error.

I have checked all my build paths and JRE
I have checked that the jsf-impl.jar is complied with Major 49 version (Java 1.5). But the error which I am getting is from a class in this jar
Caused by: java.lang.UnsupportedClassVersionError: com/sun/faces/config/FacesInitializer : Unsupported major.minor version 52.0 (unable to load class com.sun.faces.config.FacesInitializer)
at org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:2948)
at org.apache.catalina.loader.WebappClassLoader.findClass(WebappClassLoader.java:1208)
I have tried all permutation and combination but it still doesn't work. Attached are the screenshots of my project's JDK settings.
here are the images of my settings
Compiler Settings
I can assure you that my Tomcat 7.0 is also running on JRE 1.7 (Unfortunately I cannot post more than 2 links)

From your list of JARs,
- javax.faces-2.3.0-m04.jar
- jsf-api.jar
- jsf-impl.jar
Provided that jsf-impl.jar is compiled with Java 1.5, then this indicates that it's JSF 2.0. You're thus basically mixing JSF 2.3 (beta) and JSF 2.0 in one and same webapp. This makes no sense. JSF 2.3 is compiled with Java 1.8 and JSF 2.0 is compiled with Java 1.5. As per your exception, the JSF 2.3 classes got precedence in classloading and are actually being used.
Get rid of the JSF 2.3 JAR file.
If you still continue running after "fixing" the Java version, you'd sooner or later face one of following problems caused by mixing multiple different versioned JSF libraries:
- java.lang.IllegalStateException:Could not find backup for factory javax.faces.application.ApplicationFactory
- java.lang.IllegalStateException : Could not find backup for factory javax.faces.context.FacesContextFactory
- @ViewScoped calls @PostConstruct on every postback request
- Identifying and solving javax.el.PropertyNotFoundException: Target Unreachable
Just do not mix multiple JSF libraries.

- Do I need jsf-api or jsf-impl or both to start using JSF? Why are they not merged?
