Java unsupported major minor version 52.0 [duplicate]

Solution 1:

Your code was compiled with Java Version 1.8 while it is being executed with Java Version 1.7 or below.

In your case it seems that two different Java installations are used, the newer to compile and the older to execute your code.

Try recompiling your code with Java 1.7 or upgrade your Java Plugin.

Solution 2:

You have to compile with Java 1.7. But if you have *.jsp files, you should also completely remove Java 1.8 from the system. If you use Mac, here is how you can do it.

Solution 3:

I noticed that in netbeans Apache configuration in the servers tab. you can state the platform for your web application. I changed to 1.8 and it worked fine. (I am targeting java 8 platform in my application). Hope that might t help.
