Installation of the latest eclipse Java EE IDE in (K)Ubuntu 11.04 x64

Prerequests

• Java JRE (ubuntu packages sun-java6-jre or openjdk-6-jre).
• Current Ubuntu repositories package (eclipse 3.5 (galileo)), which will be purged after installation/configuration of the latest eclipse. If it is not present install it using the command:
  

  sudo apt-get install eclipse

Download

• The latest eclipse version (currently eclipse 3.7 (indigo) eclipse-jee-indigo-linux-gtk-x86_64.tar.gz).

Installation/Configuration

• To (temporally) install the latest version (placed for example in ~/Downloads) at /usr/lib/eclipse_indigo/eclipse, open a terminal and give the commands:
  

  cd /usr/lib
  sudo mkdir eclipse_indigo
  cd eclipse_indigo
  sudo tar zxvf ~/Downloads/eclipse-jee-indigo-linux-gtk-x86_64.tar.gz

• Keep the current (executable) script:
  

  sudo cp /usr/bin/eclipse /usr/bin/eclipse.curr

• Purge ubuntu eclipse:
  

  sudo apt-get purge eclipse
  sudo apt-get autoremove

• Move (as root) the latest eclipse from /usr/lib/eclipse_indigo/eclipse to /usr/lib:
  

  sudo rm -r /usr/lib/eclipse
  sudo mv /usr/lib/eclipse_indigo/eclipse /usr/lib
  sudo rmdir /usr/lib/eclipse_indigo

• Move back (as root) the executable /usr/bin/eclipse:
  

  sudo mv /usr/bin/eclipse.curr /usr/bin/eclipse

• Open as root the file /usr/bin/eclipse and change all occurrences of galileo to indigo.
• Copy /usr/lib/eclipse/eclipse.ini to /etc
  

  sudo rm /etc/eclipse.ini
  sudo cp /usr/lib/eclipse/eclipse.ini /etc

• As root create the file /usr/share/applications/eclipse.desktop to make a new (kde) menu entry:
  

  [Desktop Entry]
  Comment[en_US]=
  Comment=
  Exec=/usr/bin/eclipse
  GenericName[en_US]=Eclipse 3.7 (Indigo)
  GenericName=Eclipse 3.7 (Indigo)

  X-DBUS-ServiceName=
  X-DBUS-StartupType=
  X-KDE-SubstituteUID=false

  If this entry is placed in "Lost & Found" menu category, move it to "Development", using the KDE Menu Editor.

Installation of latest Liferay IDE (using eclipse-postgreSQL+postgis) in (K)ubuntu 11.04 x64

Prerequests

• Java JRE (ubuntu packages sun-java6-jre or openjdk-6-jre).
• Latest eclipse (click here for installation instructions)
• PostgreSQL 9 (click here for installation instructions).

Downloads

• The latest liferay portal tomcat version (which now is liferay-portal-tomcat-6.0.6-20110225.zip).
• The latest liferay plugins sdk (for the time being is liferay-plugins-sdk-6.0.6-20110225.zip).
• The latest liferay portal sql files (currently liferay-portal-sql-6.0.6-20110225.zip)
• The latest PostgreSQL jdbc driver (currently postgresql-9.0-801.jdbc4.jar).

Installation

Assuming that

• liferay portal and plugins sdk will be installed in home directory and
• downloded files are placed in ~/Downloads

open a terminal and give the commands:

cd
unzip Downloads/liferay-portal-tomcat-6.0.6-20110225.zip
mkdir liferay-plugins-sdk-6.0.6
cd liferay-plugins-sdk-6.0.6
unzip ../Downloads/liferay-plugins-sdk-6.0.6-20110225.zip

Problems

For eclipse/Liferay to be able to correctly locate PostgreSql/postgis jdbcs:

cp ~/liferay-portal-6.0.6/tomcat-6.0.29/lib/ext/postgresql.jar ~/liferay-portal-6.0.6/tomcat-6.0.29/lib/ext/postgresql.jar.1
cp ~/Downloads/postgresql-9.0-801.jdbc4.jar ~/liferay-portal-6.0.6/tomcat-6.0.29/lib/ext/postgresql.jar
sudo cp /opt/PostgreSQL/9.0/PostGIS/java/jdbc/postgis* ~/liferay-portal-6.0.6/tomcat-6.0.29/lib/ext

Next Steps

To set PostgreSQL as the default database of Liferay:

• Extract the file create-minimal-postgresql.sql from the downloaded liferay-portal-sql-6.0.6-20110225.zip,
• create database lportal using the command

psql -f create-minimal-postgresql.sql -U <user_name>

• and follow the instructions of this link to configure Liferay.

Installation of the latest (postgis enabled) PostgreSQL in (K)Ubuntu 11.04 x64

Download
Latest version of  PostgreSQL Graphical Installer (for the time being is postgresql-9.0.4-1-linux-x64.bin)

Installation

• To install  PostgreSQL at /opt directory, call the Graphical Installer:

sudo chmod 0755  postgresql-9.0.4-1-linux-x64.bin

sudo ./postgresql-9.0.4-1-linux-x64.bin

• Optionally, install  postgis-1.5, using the Application Stack Builder before closing Graphical Installer. Otherwise, you may install it later, by calling the Application Stack Builder entry in your (kde/gnome) menu (after resolving the corresponding problems (see below)).

Configuration
Edit ~/.profile and append the line

source /opt/PostgreSQL/9.0/pg_env.sh

at the end, to update $PATH and set other env variables (you have to logout/login, for this change to take effect).

Problems

• Execution of

/opt/PostgreSQL/9.0/stackbuilder/bin/stackbuilder

executable failed, with a number of messages for missing libraries. The following links to (installed) libraries had to be set:

sudo ln -sf  /usr/lib/x86_64-linux-gnu/libtiff.so.4.3.3 /usr/lib/x86_64-linux-gnu/libtiff.so.3

sudo ln -sf /lib/x86_64-linux-gnu/libexpat.so.1.5.2 /lib/x86_64-linux-gnu/libexpat.so.0

Depending on your current installation, other links to libraries (or the libraries themselves) may be missing as well. You have to locate those libraries (and if they miss, to install them) and make the corresponding links.

• To be able to run stackbuilder from the (kde) menu entry, edit (as root) the file

/usr/share/applications/pg-stackbuilder-9_0.desktop

and change the line

Exec=/opt/PostgreSQL/9.0/scripts/launchstackbuilder.sh

to

Exec=kdesudo /opt/PostgreSQL/9.0/scripts/runstackbuilder.sh

• To correct the (postgis related) problem of "$libdir/postgis-1.5.so not found", execute the command:

sudo ln -sf /opt/PostgreSQL/9.0/lib/postgis-1.5.so /opt/PostgreSQL/9.0/lib/postgresql/postgis-1.5.so
