The Java Compiler (javac) and the Java Runtime Environment (JRE) are required for JCF to properly operate. These requirements ensure that you can perform compilation of Java class files and execute generated Java code. Additionally, JDK is required if you plan to utilize the full range of functionalities provided by JCF, including creating, updating, and removing the required annotations. Here are the specific requirements for different operating systems:
Windows:
- You need to install the latest JDK provided by Oracle or OpenJDK, which contains both javac and JRE, and set the JAVA_HOME environment variable to point to the installed JDK directory.
- You should ensure that JCF jars (jcf.jar and JCRAnnotations.jar) are stored in a directory added to the classpath of your application or available system-wide.
