NoClassFoundError on websphere

[Yogesh Gandhi]

I have one struts 2 web application war file, which is running on my local tomcat.

I checked inside WEB-INF/lib and it has all the required dependencies (for struts 2) -- Jars.jpg attached.

I assume that if my WEB-INF/lib directory contains the required jars, I should not be providing the jars anywhere else.

When I deployed the same war file on websphere, I am getting class not found exception. / No Class found def error.

Can someone please help me in resolving the errors?

java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version;

That error looks like the class file was created by a younger version of java compared with the JVM's version of java

Thanks for taking out your precious time and replying to my post.

Yes, you are right, and this was the exact issue.

Actually I was using commons-lang3-3.11 version which I downloaded from maven repository and it was built using java 1.8
When I found this, I downloaded the lower version of the commons-lang, which was compiled using java version 1.5

Since i was using java version 1.6 on my websphere, putting this new jar solved my problem.

I used to work with Websphere and yes, I know it takes a long time to get a new version running in an organization. All the dependencies, all the work you have to do to replicate the "features" which change from one version to the next, all the people that have to approve it and schedule it and all that.

But even so, you really ought to get your Websphere upgraded to at least something which uses Java 8!
