jackrabbit - There is an error in invoking javac. A full JDK (not just JRE) is required

I'm learning Jackrabbit and following the documentation to run a standalone server. When I run the command java -jar jackrabbit-standalone-2.16.2.jar and access localhost:8080 on my browser, I get a 500 error saying:

org.apache.jasper.JasperException: PWC6345: There is an error in invoking javac. A full JDK (not just JRE) is required

What am I doing wrong?

Note: I have set my jdk/bin path in my environment variables.Also, my javac command is working properly. I've jdk version 1.8.0_74 and Jackrabbit version 2.16.2

Edit: According to this answer, I tried setting my jdk to my installed jres in eclipse but that didn't solve my problem.

Running the latest jackarabit standalone jar(2.17.3) in my machine(windows 10 and java home pointing in java8 jdk) produced the same errors.

I then executed the rar with java -Djava.home="%JAVA_HOME%" -jar jackrabbit-standalone-2.17.3.jar. Although I got the same error in browser I was able to see errors in the console where I invoked the running command.

One of these error was can't open C:\Progra~1\Java\jdk1.8.0_144\lib\tzmappings.

Searching my java installation I found that the missing files, are located under jre's installation folder.

So I eventually made the standalone jar to work with: java -Djava.home="%JAVA_HOME%\jre" -jar jackrabbit-standalone-2.17.3.jar

The initial error is a bit misleading as it refers to javac and not to the missing files.

The whole thing seems to be a bug for me. Please give a try to my workaround and if it works for you consider filing a bug in Jackrabbit's issue tracker platform.

I found that there was another variable in the Path environment System variable preceding my %JAVA_HOME%\bin variable.

You don't have to delete the other variable, but move it down (or move %JAVA_HOME\bin up) to correct the load order.

jackrabbit-standalone uses JSP. JSP needs compilation. Compilation needs JDK.

Before running java -jar jackrabbit-standalone-2.16.2.jar do you check your JAVA_HOME, and make sure it refers to a fully-fledged JDK? In short, the bin directory should have javac.
