Answer 1

A JDK is required to compile your JSP files. To fix your problem, you will need to use a JDK instead of a JRE for your Eclipse.

You should do the following:

• Go to Window->Preferences->Java->Installed JREs. Make sure that you point to a JDK here and not JRE.

The above should address your problem. Restart Eclipse - just in case. If not, do the following:

• If your Eclipse is still not able to take that setting, you will need to specify the JDK in the eclipse.ini file in the -vm arguments. Check this answer if you have problems setting it up in the eclipse.ini file : changing jdk in eclipse
