There is no Java 8 in my server

It's clearly reporting a jdk mismatch: `Unsupported major.minor version 52.0`. 52 is Java 8. https://stackoverflow.com/questions/22489398/unsupported-major-minor-version-52-0 — Roddy of the Frozen Peas, Jul 12 '17 at 22:40

There's no Java 8 on your server, but your code is compiled with it and is complaining that you have an incompatible jdk. — Roddy of the Frozen Peas, Jul 13 '17 at 05:51
@BruceWayne, Please go through this tutorial. http://mswiderski.blogspot.com/2015/10/installing-kie-server-and-workbench-on.html . It may help you. — SkyWalker, Jul 19 '17 at 13:22
Yes, you should use Java 8 and I don't know if you are missing some steps that you can find in the above link provided by @SkyWalker, also the version that you are using of Kie Workbench was released for tomcat 8 BUT should works without issues in tomcat 8.5 too. Follow the guide and let us know how it goes — Bryan Acuña Núñez, Jul 19 '17 at 20:58

You need to either:

1) change your dependencies list to reference only JDK 1.7 compatible libraries

2) install and run your application using JDK 1.8

The problem, as explained in the message, is that the ClassLoader can not load the class(es) javax.inject.Provider, javax.enterprise.inject.Instance and/or javax.enterprise.inject.spi.CDI since they were compiled with Java 1.8. You can try to find older versions of the corresponding jars, but that may lead to incompatibilities with your actual code. I suggest you to upgrade your production JDK to the latest of the 1.8 branch.

By the way, JDK 1.7 is end of life and should not be used anymore: http://www.oracle.com/technetwork/java/eol-135779.html#Java6-end-public-updates

You need to run and compile your application on 1.8 version of Java.

For Eclipse you should do :

1) click on "Window > Preferences", and in the window that appears,left side, under "Java", click on "Installed JREs", click on "Add..." navigate to folder that contains the JDK.

2) Right-click on project and click "Properties", in the window left side, click on "Java Compiler" and uncheck "Use compliance from execution environment on the Java Build Path", that is allows you to choose the list "Compiler compilance level" use the same version whitch you set in the previous step.

for NetBeans IDE, right click on the project and select Properties then go to sources, then you can change the Source/Binary Format to a upper JDK version.

Its not about compile. Final version is already available over drools website. While starting the drools service over tomcat with downloaded `war`, getting the error. — BruceWayne, Jul 17 '17 at 06:44
