Hello everybody, I need to compile generated Java source code on JBoss inside of a EJB3. I already migrated the JSR 199 compiler API of Java 7 to libraries that can be used in ordinary Java 5 standalone applications. The JSR 199 Java Compiler API works pretty well and does not need any access to the underlying file system. This is everything I need. But JBoss is running on a JRE, only Tomcat use the JDK. | JavaCompiler compiler = ToolProvider.getSystemJavaCompiler(); | This is the reason why the compiler object in the code above is null. How can I run JBoss on a JDK. I couldn't be so difficult, or am I wrong? Thank you in advance, Marco View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4078672#...
