Hi list,
I have a webapp which needs to compile some jsp
I tried the suggestions in
http://www.eclipse.org/jetty/documentation/current/configuring-jsp.html#compiling-jsps
to instruct jetty to use it's internal compiler, but I still get
org.apache.jasper.JasperException: Unable to compile class for JSP

Caused by: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK

Googling I found other "solution" proposed, from explicit setting
JAVA_HOME to adding the directory which contains tools.jar to classpath,
nothing worked for me
The only thing that worked was to copy the file tools.jar from
$JDK/lib/tools.jar to $JDK/jre/lib/ext/tools.jar
I'm using
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
and jetty 9.1.0
Any hint appreciated
