Continuum Standalone - A full JDK is required But I've verified my classpath and java_home

Question

Trying to run Continuum in a standalone environment.

After running the following:

C:\Program Files\apache-continuum-1.4.1\bin>continuum console

Everything is OK until I go navigate to

http://localhost:8081/continuum/

Doing so I get the error:

jvm 1    | org.apache.jasper.JasperException: PWC6345: There is an error in invo
king javac.  A full JDK (not just JRE) is required

However, this doesn't make sense for the following reasons:

1. Typing C:\Program Files\apache-continuum-1.4.1\bin>javac brings up what I'd expect.

   C:\Program Files\apache-continuum-1.4.1\bin>javac -version javac 1.7.0_25

2. I've checked my PATH's

   JAVA_HOME: C:\Program Files\Java\jdk1.7.0_25 CLASSPATH: ..;\C:\Program Files\Java\jdk1.7.0_25\bin;...

Is there something else missing?

Answer 1

The CLASSPATH looks wrong (leading \ on C:, though it might be a typo). However that should not be required so I'd recommend unsetting it first to rule it out.

You should verify JAVA_HOME is correct by running %JAVA_HOME%\bin\javac. On Windows a different javac is on the path and is a system binary, so it doesn't guarantee everything else is right.

This question is likely related: Ant "JAVA_HOME does not point to the JDK" - but it does. I think the JSP compiler uses tools.jar in the same way to invoke the compiler rather that running javac from the command line, so it has some additional suggestions to follow.
