UnsupportedClassVersionError - org/primefaces/rain/component/RainMenu

[cslpa]

I bought the rain theme and tried to implement in our web application running with Eclipse on Websphere 8 JDK as the Installed JRE.

I encountered this error:
Caused by: java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=org/primefaces/rain/component/RainMenu, offset=6

Can please someone assist with why this issue is happening? Appreciate any feedback. Thanks.

Hi,

Websphere 8 supports Java6 or 7 but we are using java8. Maybe the reason was this. But i am not sure about this. Please change these on pom.xml file and try again:

Code: Select all

<plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.7.0</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                    <encoding>${project.build.sourceEncoding}</encoding>
                </configuration>
            </plugin>
    ...
</plugins>

But as far as I researched, your issue is related to java version.
