Install Eclipse on Ubuntu 12.10 64bit

This article describes process about:
- installation of JVM;
- installation of Eclipse IDE;
- tunning the Eclipse IDE for starting  from launch panel.

Installation of JDK.

1.  Go to Java SE Downloads page and download archive .tar.gz with newest version of JDK - jdk-XuXX-linux-x64.tar.gz.
2. Go to Eclipse Download page and downdload Eclipse IDE for Java EE Developers for Linux 64 bit.
3. Suggest that download catalog is ~/Download.
4. Go to ~/Download
   
   

5. cd /Download

   
   and unpacking our JDK - jdk-XuXX-linux-x64.tar.gz.
   
   

   tar xvfz JDK - jdk-XuXX-linux-x64.tar.gz
   

6. move the JDK 7 directory to /usr/lib
   

   sudo mkdir -p /usr/lib/jvm
   sudo mv ./jdk.1.7.0_02 /usr/lib/jvm/jdk1.7.0

7. Now run
   

   sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0/bin/java" 1
   sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0/bin/javac" 1
   sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7.0/bin/javaws" 1

8. Correct the file ownership and the permissions of the executables:
   sudo chmod a+x /usr/bin/java sudo chmod a+x /usr/bin/javac
   sudo chmod a+x /usr/bin/javaws
   sudo chown -R root:root /usr/lib/jvm/jdk1.7.0
9. Run
   

   sudo update-alternatives --config java

10. If you have a problem with maven like this
    
    Missing artifact com.sun:tools:jar:1.5.0:system pom.xml
    
    You can have eclipse start up using your built in JDK by altering the eclipse.ini and adding something like
    
    -vm
    /usr/java/jdk1.7.0_17/bin/java
    
    The example of eclipse.ini in Linux:
    
    -startup
    plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.gtk.linux.x86_1.1.200.v20120913-144807
    -product
    org.eclipse.epp.package.jee.product
    --launcher.defaultAction
    openFile
    -showsplash
    org.eclipse.platform
    --launcher.XXMaxPermSize
    256m
    --launcher.defaultAction
    openFile
    -vm
    /usr/java/jdk1.7.0_17/bin/java
    -vmargs
    -Dosgi.requiredJavaVersion=1.5
    -Dorg.eclipse.swt.browser.DefaultType=webkit
    -Dhelp.lucene.tokenizer=standard
    -XX:MaxPermSize=256m
    -Xms40m
    -Xmx512m

11. If you have problem like this:
    
    Unhandled event loop exception No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]
    
    I founded the solution here askubuntu
    
    Use Webkit instead of XULRunner
    Install the package  and configured Eclipse  to use Webkit instead of Xulrunner by adding this line to the eclipse.ini:
    
    -Dorg.eclipse.swt.browser.DefaultType=webkit
    
    Restart Eclipse.
12. If you have problem like this:
    
    Event log:
    
    Unhandled event loop exception
    
    
    org.eclipse.swt.SWTError: No more handles
    at org.eclipse.swt.SWT.error(SWT.java:4445)
    at org.eclipse.swt.SWT.error(SWT.java:4334)
    at org.eclipse.swt.SWT.error(SWT.java:4305)
    at org.eclipse.swt.browser.Browser.<init>(Browser.java:103)
    
    Just:
    sudo apt-get install libwebkitgtk-1.0-0
