WAS choose faces implementation 30. January 2013

Because WAS7 ist JEE5 compiant –
and every JEE5 container need to deliver a JSF 1.2 .
WAS7 gives you the option to choose which JSF-Implementation you want to provide for the app.

The following Screenshot tells you how to do this.

By the way – Did you notice that IBM does not offer the option to choose an IBM-Implementation of JSF 1.2
That’s the reason why we have to deal with the old JSF 1.1 version in our app.
Migration is very difficult.
>
I read that with JEE7 (comming mai 2013) – JSF 2.2 will be part of the spezifikation.

OpenJPA DB2 hellojpa 29. January 2013

In order to execute the sample app, you need to create the table in your Database.
In our case the user/owner ist called TESTUSR.
The table definition works fine with the sample, and it has soem adtional features.

CREATE TABLE TESTUSR.MESSAGE (
ID BIGINT GENERATED BY DEFAULT AS IDENTITY(START WITH 1) PRIMARY KEY,
CREATED DATE DEFAULT CURRENT_DATE NOT NULL,
MESSAGE VARCHAR(2000) NOT NULL
);
INSERT INTO TESTUSR.MESSAGE (MESSAGE ) VALUES  ( 'hi2' )

don’t forget the configuration of your persistence.xml.
In our case we set 4 parameters.
It is also possible to use a datasource in hosted appserverenvironment.
Because we are assuming the simple we choose to set the minimal necessary parameters.

In order to connect to a remote java process. The JVM must be started in debugging-mode.

Perlin noise with Javascript

In Three.js a version of the Perling noise algorithm is used. They called it improved Noise. The noise-function is used in the terrain landscaps.

The Math.random()-Funktion produces other results, that we can’t use in dynamic computer graphics.

In our simple example we assume a quite small and simple landscape.
For every point in the landscape we have to calcualte a third value the height.

It starts by gennerating a random number.
var z = Math.random(100);

The noise-function is called with 3 parameters,
var perlin = new ImprovedNoise();
perlin.noise(x,y,z);

ANSI and UTF-8 without BOM

Java expects that textfiles doesn’t have any BOMs.

From Wikipedia, the byte order mark (BOM) is a Unicode character used to signal the endianness (byte order) of a text file or stream. Its code point is U+FEFF. BOM use is optional, and, if used, should appear at the start of the text stream. Beyond its specific use as a byte-order indicator, the BOM character may also indicate which of the several Unicode representations the text is encoded in.

// FEFF because this is the Unicode char represented by the UTF-8 byte order mark (EF BB BF). Java-Representation of a BOOM

public static final String UTF8_BOM = "uFEFF";

IF the file right in front of you doesn’t containt any special characters, there is no difference between a ANSI-Version of the file.

If you want to read a File with a BOM in Java have a look at
