javac

I want to pass any enum value to method in utility class and get another enum value of same enum type. Something like this: public class XMLUtils { public static Enum<?> getEnumAttribute(Element element, String name, Enum<?> defaultValue) { if (element.hasAttribute(name)) { String valueName = element.getAttribute(name); // search for value for (Enum<?> value: defaultValue.getClass().getEnumConstants()) if (value.toString().equalsIgnoreCase(valueName)) return value; } // not found, return default value return defaultValue; } } Use of method getEnumAttribute() : // simple enum public enum

This page describes how I can use the code generator in javac to generate code given that I can build an AST (using a separate parser which I wrote). The technique involves editing javac's source code to basically bypass the Java parser, so that one could supply his/her own AST to the code generator. This could work, but I was hoping to do it in a slightly cleaner way. I want to include the code generating part of javac as a library in my project so I can use it to generate code, without bringing with it the rest of javac's source. Is there a way to do this with javac, or is there perhaps a

I'm making my first steps toward learning JSF. I found this interesting book called "Core JavaServer Faces Third Edition". Trying to compile the first example, you can download the source code from: http://horstmann.com/corejsf/ . When I type the following on the command-line javac UserBean.java I get errors: package javax.inject does not exist package javax.enterprise.context doe not exist I have downloaded Java EE, Ant and GlassFish. Here is a snap of my command-line: C:\JSF-Tutorial\corejsf3-examples\javaee\ch01\login\src\java\com\corejsf>javac UserBean.java UserBean.java:4: error: package

I have three java types as defined below: Main.java: import java.util.Arrays; import java.util.List; public class Main { private Object callFunction() { OperationDefinitions func = OperationDefinitions.CONCATENATE; List<Object> values = Arrays.asList(new Object[] {"ABC", "-", "DEF"}); return func.call (values); } public static void main (String[] args) { Main main = new Main(); System.out.println (main.callFunction()); } } Operation.java import java.util.List; public interface Operation { abstract Object call(List<Object> params); } OperationDefinitions.java import java.util.List; enum
