I was trying to create a class to compile some .java that I'll create at runtime, but I can't get this to work properly.
Here's my code
File bin = new File(args[args.length-1]);
System.setProperty("java.home", "C:\\Program Files\\Java\\jdk1.7.0_60");
JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
StandardJavaFileManager standardJavaFileManager = compiler.getStandardFileManager(null, null, null);
try {
standardJavaFileManager.setLocation(StandardLocation.CLASS_OUTPUT, Arrays.asList(bin));
} catch (IOException e) {
System.err.println("Invalid bin directory");
e.printStackTrace();
}
List<String> options = new ArrayList<String>();
options.add("-Xlint:unchecked");
options.add("-classpath");
options.add("e:\\ParentProject.jar");
System.out.println(options);
CompilationTask compilationTask = compiler.getTask(null, standardJavaFileManager, null, options, null, standardJavaFileManager.getJavaFileObjectsFromFiles(archives));
compilationTask.call();
I'm trying to compile a Son.java that extends a class that is in the ParentProject.jar, but it doesn't work, even using the "-classpath" flag. However, if I add the jar to the build path of the compiler project, it works (and it doesn't need the classpath flag). Is this the normal behaviour ?
And that leads to another problem. When I try to use this piece of code in a project that is running on a Tomcat server, even with the jars in WEB-INF/lib, I can't get it to work.
