Install the java environment and eclipse In Debian

Install the java environment In Debian and the Debian information in eclipse-Linux release technology. The following is a detailed description. Download the latest jdk 1.5, http://java.sun.com from sun's official website. Note: Download and decompress the version.
# Su root
Switch to the Super User and enter the download directory.
# Chmod a + x jdk-1_5_0-linux-i586.bin
#./Jdk-1_5_0-linux-i586.bin

Agree to the agreement. A jdk-1.5.0 directory will be obtained.
# Mkdir/usr/lib/j2se
# Mv jdk-1.5.0/usr/lib/j2se/5.0
# Cd/usr/lib
# Ln-s/usr/lib/j2se/5.0 java

Edit the/etc/mailcap file and move the java web start Settings to the top of the file. Otherwise, the custom settings will be washed out during update-mime.

# ----- User Section Begins -----#
# ----- User Section Ends -----#

Changed:

# ----- User Section Begins -----#
# Java Web Start
Application/x-java-jnlp-file;/usr/lib/java/jre/bin/javaws % s
# ----- User Section Ends -----#

Okay, basically it has been installed. The following describes the system dependencies.

# Apt-get install java-common
At this time, detailed documents of debian java are available in/usr/share/doc/java-common:
Debian-java-faq
Debian-java-policy

# Cd/usr/share/doc/java-common/dummy-packages/
There are 5 files:
Java1-runtime-dummy.control
Java2-compiler-dummy.control
Java2-runtime-dummy.control
Java-compiler-dummy.control
Java-virtual-machine-dummy.control

First, make sure that equivs has been installed. (If you have not installed equivs, run apt-get install equivs first)
# Equivs-build java1-runtime-dummy.control
# Equivs-build java2-compiler-dummy.control
# Equivs-build java2-runtime-dummy.control
# Equivs-build java-compiler-dummy.control
# Equivs-build java-virtual-machine-dummy.control
Generate five. Deb package.
# Dpkg-I *. deb

# Cp/usr/lib/java/jre/plugin/desktop/sun_java.desktop/usr/share/control-center-2.0/capplets/
Edit/usr/share/control-center-2.0/capplets/sun_java.desktop
Modify the java path:

[Desktop Entry]
Name = Java
Comment = Java Control Panel
Exec =/usr/lib/java/bin/ControlPanel
Icon =/usr/lib/java/jre/plugin/desktop/sun_java.png
Terminal = 0
Type = Application
Categories = Application; Settings; X-Sun-Supported; X-Red-Hat-Base;

In this way, you can start the java console through the menu.

Finally, create a link for the command under jdk bin, install the plug-in for mozilla, and create a shell file with the following content:

#! /Bin/bash
JDK_HOME =/usr/lib/java

For I in $ JDK_HOME/bin/*; do
Altname = 'basename $ I'
Echo "Processing $ altname ..."
Echo ""

If [-x "$ I"-a-e "$ JDK_HOME/man/man1/$ {altname}. 1"]
Then
Update-alternatives -- verbose -- install/usr/bin/$ altname $ I 500
-- Slave/usr/share/man/man1/$ {altname}. 1 $ {altname}. 1 $ JDK_HOME/man/man1/$ {altname}. 1
Else
Update-alternatives -- verbose -- install/usr/bin/$ altname $ I 500
Fi
Done

Update-alternatives -- verbose -- install/usr/lib/mozilla/plugins/libjavaplugin. so libjavaplugin. so $ JDK_HOME/jre/plugin/i386/ns7/libjavaplugin_oji.so 500
# Update-alternatives -- install/usr/share/gnome/vfolders/Settings/sun-java.desktop/usr/lib/java/jre/plugin/desktop/sun_java.desktop 500

# Sh your_shell

Test:
# Java-version
Output:
Java version "1.5.0"
Java (TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot (TM) Client VM (build 1.5.0-b64, mixed mode, sharing)
# Man java
You can check the usage of java.

Finally install eclipse

Apt-get install eclipse

An error is prompted during startup, and the version is incorrect. You can modify it as follows:

Gedit/etc/eclipse/java_home

Modify one of them to your JAVA_HOME path. Change one of them to/usr/lib/java.

/Usr/lib/jvm/java-gcj

/Usr/lib/kaffe/pthreads

/Usr/lib/jvm/java-1.5.0-sun

/Usr/lib/j2se/1.5

/Usr/lib/j2se/1.4

/Usr/lib/j2sdk1.5-ibm

/Usr/lib/j2sdk1.4-ibm

/Usr/lib/j2sdk1.5-sun

/Usr/lib/j2sdk1.4-sun

(In this step, you can open/usr/bin/eclipse to find the path. In addition, eclipse can be obtained by creating a desktop starter from the application, from the perspective of attributes .)

Run it again.
