The scomp program can't find javac and fails with java.io.IOException on Windows!
On Windows, some users have reported that the scomp program fails when trying to run javac on the generated java source. First, be sure you have a JDK installed. The JRE doesn't have the javac program so you won't be able to compile the generated java source. If you have both a JDK and a JRE installed, the JRE's java is being found before the JDK's java. Since scomp uses the 'java.home' property to find the javac program, but javac is only available in the JDK, finding javac will fail.
The solution is to move the JDK higher up on the PATH in the environment. An alternate solution is to set JAVA_HOME and edit the scomp script to run %JAVA_HOME%\bin\java instead of relying on the PATH. The error you would see looks like:
$ scomp -out myeasypo.jar easypo
Time to build schema type system: 1.969 seconds

'javac' is required on the path.
