Install on Ubuntu.

Main install:
"sudo aptitude install sun-java5-jdk"
Set up Sun's JVM as default:
"sudo update-java-alternatives -s java-1.5.0-sun" or "sudo gedit /etc/jvm"

For eXo java/jdk1.5
Set up system environments for java snd maven within your home dir .profile file
export JAVA_HOME=/home/alexey/java/jdk1.5
export MAVEN_HOME=/home/alexey/java/maven2
Links official and not official

Here some usefull java code pieces would be posted.

Collection to Array:
vector -> string array
String[] strArray = vector.toArray(new String [vector.size()]);
list -> string array
String[] strArray = list.toArray(new String [list.size()]);

Array to Collection:
vector = Arrays.asList(strArray);

Enumeration to Collection
return Collections.list(returnedEnumeration);

Collection to Enumeration
return Collections.enumeration(returnedColection);

How to return Collection
Collection v = new ArrayList();
return v;

How to return Enumeration
public Enumeration<string> getProperties(String s) {
// creating typified
Vector<string> result = new Vector<string>();
// fill with sample string
// make return statement
return result.elements();

How get InputSource from org.w3c.dom.Document?
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.TransformerFactory;

Document doc = ... // your existing DOM document
DOMSource source = new DOMSource(doc);
StringWriter xmlAsWriter = new StringWriter();
StreamResult result = new StreamResult(xmlAsWriter);
TransformerFactory.newInstance().newTransformer().transform(source, result);
StringReader xmlReader = new StringReader(xmlAsWriter.toString());
InputSource viola = new InputSource(xmlReader);

Read and write line in file
BufferedReader in;
try {
in = new BufferedReader(new InputStreamReader(new FileInputStream("c:\\in.xml")));
while (in.ready()) {
String s = in.readLine();
} catch (IOException e) {
try {
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("c:\\out.xml",true)));
} catch (IOException e) {

Print Exception to print stream (ex.: PrintWriter w = renderResponse.getWriter();)
(new Exception()).printStackTrace(w);
StackTraceElement[] ste = Thread.currentThread().getStackTrace();

это частный случай official
url = http://localhost:8080/portal/portal/?portal:componentId=producer1-1556486924@portlets/HelloWorld
protocol http
host localhost
port 8080
getAuthority localhost:8080
getPath /portal/portal/
getQuery portal:componentId=producer1-1556486924@portlets/HelloWorld
getFile /portal/portal/?portal:componentId=producer1-1556486924@portlets/HelloWorld
toExternalForm http://localhost:8080/portal/portal/?portal:componentId=producer1-1556486924@portlets/HelloWorld
getRef null

request.getContextPath() = /portal
request.getServletPath() = /portal/
request.getServerName() = localhost
request.getRequestURL() = http://localhost:8080/portal/portal/
request.getRequestURI() = /portal/portal/

Install JDK

howto jdk on ubuntu wiki
sudo aptitude install sun-java5-jdk
update-alternatives --config java

In your home directory within .profile file add lines with changes according your path:
export JAVA_HOME=/home/alexey/java/jdk1.5
export PATH=$JAVA_HOME/bin:$PATH

Download page
Direct link 3.0.4 !
License for 1 month

Picture1: info

Picture3: add ignore
(Project -> Settings ...)
Note: window resizing on compiz bug

Web Tools Platform All-In-One Package:

Configure Eclipse it at "Window" -> "Preferences..."

Setting formatter:
Java -> Code Style -> Formatter
Choose: "Edit..." or "Import..." or "Export..."
Example: "Import..." this file

Setting templates:
Java -> Editor -> Templates
Choose: "New..." or "Import..." or "Export..."
e.g.0: "Import..." this file
e.g.1: "Edit..." for sysout: "System.out.println(">>> ${user}: ${enclosing_type}.${enclosing_method} ${word_selection} = " + ${word_selection});${cursor}"
e.g.2: "Edit..." for systrace: System.out.println(">>> ${user}: ${enclosing_type}.${enclosing_method}()");

If Content assist doesnt work by "Ctrl"+"Space", so some application intercepts it. Check for in in SCIM. Right button on and choose "SCIM setup". Edit there hotkeys or keyboard for remove necessary for eclipse hotkeys.

Mark occurrences:
Java -> Editor ->
Mark Occurrences
Check the "
Mark occurrences of the selected element in the current file".

P.S.: If you are developer of eXo Platform then look at screenshot of my working directory (java dir within home on ubuntu)

C - is for Consumer
D - is for DestroyPortlets
E - is for Event and for Extension
F - is for Fault :(
G - is for GetMarkup and for GetResource
H - is for HandleEvents
I - is for InteractionParams and for ImportPortlets
J - is for JSR286ContainerProxyImpl and for JAXBEventTransformer
K - is for ... [1]
L - is for Lifetime

N - is for NavigationalContext
O - is for Online and for OperationFailedFault
P - is for Producer and for PortletContext

No source begins with that letter.
There are only sources containing the letter inside: PortletDescription.getKeywords() and PortletKey
No source begins with that letter.
The class QName used every where inside wsrp (javax.xml.namespace.QName)
No source begins with that letter.
No source begins with that letter.

Настало время поменять хорошую, но уже надоевшую обоину на рабочем столе.
"Please don’t hurt the web"

Начал осторожно[1] гуглить со словами "wallpaper 1680 1050"
Наткнулся на неплохой сайт с обоинами

Закачал несколько обоин, из них выбрал самую понравившуюся и поставил на рабочий стол.
Вот выложил принтскрин в моих фотках или прямой линк на картинку

Вот и всё :)
Пишите комменты, постараюсь ответить.

[1] осторожно - это под влиянием полученного утром письма с темой "Выгуглен". Далее, текст письма:
Замечательная [анти]утопия, имеющая все шансы стать реальным будущим...
И сразу после, еще не утратив послевкусия от прочитанного,
"немедленно, доктор, вот эту штучку" (с) пр. Преображенский
