Cannot start AEM

New to AEM. I am sure this is trivial but would appreciate if you can explain how to fix and why does this happen.

I renamed my quickstart jar to aem-author-p4502.jar and double click.

Get this error on browser

    Hi

    That error is usually related to the Java JDK you are running and the version of AEM you are running. If you are running AEM 6.0 without having installed any service Pack, you have to be using Java version 7 (do a java -v command from the command line to checkout your version).

    If you are running Java version 8, install Service Pack 1 or 2.

    Let me know if you need additional information

      Hi @bkg2015

      The error occurs because the StringUtils.isEmpty() method is not resolving due to missing or incompatible dependencies. To fix it:

      1. Ensure Apache Commons Lang (which contains StringUtils) is available in the classpath.
      2. Check your AEM dependencies: Make sure the correct version of commons-lang3 is included in your Maven pom.xml.
      3. Rebuild AEM: After fixing dependencies, clear cache and rebuild your project.
      4. Verify the AEM jar: Ensure the renamed aem-author-p4502.jar is correctly installed and compatible with your AEM version.

      This should resolve the StringUtils.isEmpty() issue.
