部分Windows用户反馈使用scomp程序编译生成的Java源代码时遇到问题，错误提示为java.io.IOException。本文介绍了解决方案：确保安装了JDK而非仅JRE，并调整系统环境变量中的PATH设置，或将JAVA_HOME指向JDK安装目录。

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
Time to generate code: 0.313 seconds
'javac' is required on the path.
