Install Eclipse in ubuntu

[John Wilson]

Hi
I have switched for windows to Ubuntu now. Ubuntu is a great operating system and I like its working. From last week I am using Ubuntu, I have not occurred with a single problem still. Seem that Linux based operating systems are powerful, I had heard it but I am experiencing it now. I do programming in java, I used eclipse IDE for it on windows. Eclipse is available for ubuntu, but I am not sure I can install it on ubuntu. So any help will be appreciated.

There are many ways to do this, but only one way is showed in the following concept.
Software you have to download
1) Latest JDK version from Sun.
2) Latest release of web tools from eclipse.
3) Latest apache tomcat binary.

Install packages
Sun's Java JDK
Install java-package to repackage the jdk as a .deb file. Make sure you have enabled the repositories.

sudo apt-get install fakeroot java-package

Once we are done with this we create the .deb jdk package.

fakeroot make-jpkg jdk-1_5_xxxx-linux-i586.bin

Then we install the new package

sudo dpkg -i sun-j2sdk1.5xxxx+updatexxx_i386.deb

Make java configuration

sudo update-alternatives --config java

Tomcat
Download and copy tomcat

tar xzf apache-tomcat-5.5.15.tar.gz
sudo mv apache-tomcat-5.5.15 /opt/
cd /opt
sudo chown -R root:root apache-tomcat-5.5.15
sudo chmod -R +r apache-tomcat-5.5.15
sudo chmod +x `sudo find apache-tomcat-5.5.15 -type d`
sudo ln -s apache-tomcat-5.5.15 tomcat

Edit the users of tomcat

sudoedit /opt/tomcat/conf/tomcat-users.xml

Add an administration and your own

<user name="admin" password="admin" roles="manager,admin" />
<user name="yourname" password="blah" roles="manager,admin" />

Eclipse
Extract download and move eclipse to opt

tar xzf wtp-all-in-one-sdk-1.0-linux-gtk.tar.gz
sudo mv eclipse /opt/eclipse cd /opt sudo chown -R root:root eclipse
sudo chmod -R +r eclipse
sudo chmod +x `sudo find eclipse -type d`

Create an eclipse executable in your path

sudo touch /usr/bin/eclipse
sudo chmod 755 /usr/bin/eclipse
sudoedit /usr/bin/eclipse

With this contents

 #!/bin/sh
#export MOZILLA_FIVE_HOME="/usr/lib/mozilla/"
export ECLIPSE_HOME="/opt/eclipse"
$ECLIPSE_HOME/eclipse $*

Create a gnome menu item

sudoedit /usr/share/applications/eclipse.desktop

With this contents

[Desktop Entry]
Encoding=UTF-8
Name=Eclipse
Comment=Eclipse IDE
Exec=eclipse
Icon=/opt/eclipse/icon.xpm
Terminal=false
Type=Application
Categories=GNOME;Application;Development;
StartupNotify=true

Now you are set to do java programs with Eclipse
