I've decided to tackle Akka... which was going great until compile time :-/ Running Ubuntu by the way.
What I've Done So Far:
Installed JRE and JDK 7
Downloaded/Extracted Akka
Downloaded and Setup Maven
Set up PATH variables etc
All following this tutorial Tutorial
When compiling, I'm getting the following errors

I've literally copied ans pasted their final Pi.java file and tried to compile and i'm completely at a loss as how to proceed? :-(
Any ideas would be great.
The best way to get started with Akka is by using Typesafe’s Activator: there are several tutorials in there which show you how to do different things, starting from “Hello Akka” to using advanced Cluster features, you can see the full list here.
That said, your problems come from trying to run a tutorial from the 2.0.2 docs on Akka 2.2.1, which will not work.

Am trying to build openJDK8 in windows 64-bit. Following https://stas-blogspot.blogspot.com/2012/09/building-openjdk-on-windows.html for building.
OS: Windows 7-64-bit
Installed Cygwin, Visual studio 2013, Microsoft SDK, Ant and set all the paths in environment variable.
Built make and freetype 64-bit. Using jdk7 from Oracle as boot-jdk. configure was success. Then when i given

can somebody point-out the issue?
boot-jdk : java version "1.7.0_80" downloaded from Oracle. That blog is meant for openjdk 7 only. But i tried the same steps for building openjdk8 2 years back and it got success.
I am working with JOGL and it stopped working completely.
These are the errors i get:
Texture01.java:27: error: cannot access WriteCloneable
canvas = new GLCanvas(glcapabilities);
^
class file for com.jogamp.common.type.WriteCloneable not found
.\Texture01_GLEventListener.java:2: error: package com.jogamp.common.nio does not exist

IntBuffer ib = Buffers.newDirectIntBuffer(indices);
^

location: class Texture01_GLEventListener
4 errors
The Path and Classpath variables are correct, I reinstalled JDK and JOGL2 but still get an error with WriteClonable and com.jogamp.common.nio.*
Any help is appreciated!
This question already has an answer here:
Play 2.2.1 Java: Whats the equivalent of #before filters from play 1.X?
(1 answer)
Closed 8 years ago.
I am trying to use #Before interceptor in my controller
#Before(only = {"save" })
static void parseParams() {
String[] jobcategories = params.getAll("jobcategories");
for (int i = 0; i < jobcategories.length; i++) {
params.put("jobcategories[" + i + "].id", jobcategories[i]);
}
System.out.print(jobcategories);
}
but it gives me compile time error

What am I missing?
You CAN'T find it as it's from Play 1.x API #Before and other interceptors are NOT available in Play 2.x - they are replaced by Action Composition
#See similar topic
Note: Do not use documentation of Play 1.x for Play 2.x at all. In most areas they are totally different.

Seems like you are missing the commons-math3 library.
