OpenJDK

OpenJDK is recommended over OracleJDK since OpenJDK can easily be maintained by Ubuntu development team.

Installation: JDK

• OpenJDK 7

apt-get install openjdk-7-jdk 

• OpenJDK 6

apt-get install openjdk-6-jdk 

Installation: JRE

• OpenJDK 7

$ apt-get install openjdk-7-jre 

• OpenJDK 6

$ apt-get install openjdk-6-jre 

Extensions

Oracle JDK

Installation of SUN JDK

Since Ubuntu 10.04 sun-java6-jdk is moved to the partner repository so it has to be added first if it is not in the source list. Open the /etc/apt/sources.list file and make sure the following line is there.

deb http://archive.canonical.com/ubuntu lucid partner 

If it's just added, do update first.

$ apt-get update 

then install it.

$ apt-get install sun-java6-jdk 

Installation of 32 bit JDK on 64 bit Ubuntu Linux

• If it is not necessary to use the Java compiler, install ia32-sun-java6-bin instead.

• Download a 32 bit JDK from http://java.sun.com

• Install java-package to build deb file from the JDK bin file downloaded.

$ sudo apt-get install java-package

• Build deb file.

$ DEB_BUILD_GNU_TYPE=i486-linux-gnu DEB_BUILD_ARCH=i386 fakeroot make-jpkg jdk-6u7-linux-i586.bin 

• Install the deb file (e.g. sun-j2sdk1.6_1.6.0+update7_amd64.deb) just created.

It can be done by either typing

$ sudo dpkg -i sun-j2sdk1.6_1.6.0+update7_amd64.deb

or double-clicking the sun-j2sdk1.6_1.6.0+update7_amd64.deb file

• Change the JDK currently used to the one just installed.

See Update-alternatives

Problem Solving

• If the version of JDK 6 to build deb file is 'update 10' or higher and the following error is occurred,

No matching plugin was found.

edit /usr/share/java-package/sun-j2sdk.sh file.

• Find the following lines (search with the keyword "jdk-6u")

	"jdk-6u"[0-9]"-linux-i586.bin") # SUPPORTED
	    j2se_version=1.6.0+update${archive_name:6:1}${revision}
	    j2se_expected_min_size=130
	    found=true
	    ;;

• Change to

	"jdk-6u"[0-9][0-9]"-linux-i586.bin") # SUPPORTED
	    j2se_version=1.6.0+update${archive_name:6:2}${revision}
	    j2se_expected_min_size=130
	    found=true
	    ;;

• Build the deb file again

$ DEB_BUILD_GNU_TYPE=i486-linux-gnu DEB_BUILD_ARCH=i386 fakeroot make-jpkg jdk-6u7-linux-i586.bin
