How to install Oracle Java 8 JDK on Linux Mint Debian Edition

 

(1) Download the tar.gz (x86 or x64, depending on your platform)of latest JDK from the Oracle web site; (2) extract the content of the tar.gz file into /usr/local/java/ (you will need root privileges); (3) supposing the latest version is jdk1.8.0_25 then run the following commands:

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jdk1.8.0_25/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.8.0_25/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jdk1.8.0_25/bin/javaws" 1

sudo update-alternatives --set java /usr/local/java/jdk1.8.0_25/bin/java
sudo update-alternatives --set javac /usr/local/java/jdk1.8.0_25/bin/javac
sudo update-alternatives --set javaws /usr/local/java/jdk1.8.0_25/bin/javaws

Update your $JAVA_HOME by adding the following lines at the end of your /etc/profile:

JAVA_HOME=/usr/local/java/jdk1.8.0_25
export JAVA_HOME
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export PATH

Remove an older version

In case you were upgrading from an older version of Java 8 then, supposing the older version was jdk1.8.0_20, run the following commands to remove it:

sudo update-alternatives --remove javac /usr/local/java/jdk1.8.0_20/bin/javac
sudo update-alternatives --remove javaws /usr/local/java/jdk1.8.0_20/bin/javac
sudo update-alternatives --remove javaws /usr/local/java/jdk1.8.0_20/bin/javaws

and then delete the directory /usr/local/java/jdk1.8.0_20.

Remove all the other versions

In case you don’t need any other version of Java in your system, and you only need the latest, then you can safely remove the pre-installed ones by running the following commands:

sudo apt-get purge openjdk-6-jre* && sudo apt-get purge openjdk-6-jdk*

Install the Firefox Java Plugin

To install the Java plugin for Firefox run:

cd  ~/.mozilla/plugins
ln -s /usr/local/java/jdk1.8.0_25/jre/lib/amd64/libnpjp2.so

Restart Firefox and then type “about:plugins” in the location bar to confirm that the Java Plugin is loaded.

Firefox might complain you are not using the latest version of Java. In that case then you’ll have to use the IcedTea browser plugin. To install it run:

sudo apt-get install icedtea-7-plugin
cd  ~/.mozilla/plugins
rm libnpjp2.so
ln -s /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so

Troubleshooting

• to fix the problem with Unity scroll bar, which doesn’t work in Eclipse, run:

  sudo vim /usr/bin/eclipse

  and insert the following lines at the beginning of the file:

  # work around for LP #769277
  export UBUNTU_MENUPROXY=0
  export LIBOVERLAY_SCROLLBAR=0
  # end work around

• to fix the problem of Eclipse crashing at startup displaying an error dialog with the message “An error has occurred. See the log file /home/user/.eclipse/org.eclipse.platform_3.7.0_155965261/ configuration/1334402764482.log.” run the following commands:

  sudo apt-get install libswt-gtk-3-jni libswt-gtk-3-java
  sudo cp /usr/lib/jni/libswt-*.so ~/.swt/lib/linux/x86_64/
  sudo chown myusername. ~/.swt/lib/linux/x86_64/*
  sudo chmod 755 ~/.swt/lib/linux/x86_64/*

  Replace x86_64 with x86 if you have a 32-bit machine;

• Eclipse on Linux uses by default  UTF-8 as text encoding, while on Windows it uses the CP1252 one: when you transfer your source code from one system to the other some special characters (like the accented vowels) may not appear correctly in one of the systems. To fix this problem open your Eclipse on Windows and change its text encoding from CP1252 to UTF-8 from the menu Window → Preferences → General → Workspace, in the “Text file encoding” panel. To change the encoding of a file from CP1252 to UTF-8 run the following command on a Linux terminal:

  iconv --from-code=WINDOWS-1252 --to-code=UTF8 File.java

Set up Eclipse and Tomcat 7 on Linux to create Java RESTful Web Services with Jersey

 

1. Install Eclipse and Tomcat 7 by running in a terminal:

12. create your first RESTful Webservice by following this tutorial by Lars Vogel.

Your web services will be automatically deployed in the following folder:

~/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/

Your web service will be accessible through the following URI:

http://localhost:8080/UrlPattern/ClassPath/methodPath

Where:

1. UrlPattern = the root of your service set inside the tag url-pattern in the web.xml;
2. ClassPath = the path set for your class
3. methodPath = the path set for your method

All the files you put in your WebContent folder will be accessible via http through the following URI:

http://localhost:8080/UrlPattern/yourfile

Note: make sure the tag url-pattern in the web.xml is set to something like this:

<url-pattern>/rest/*</url-pattern>

and not something like this:

<url-pattern>/*</url-pattern>

Globus Toolkit 5.2 released

Globus Toolkit 5.2 promises to greatly enhance the ability to install, setup and update the GT client and service components. This has been achieved by providing binary native packages Red Hat, Fedora, Debian, Ubuntu, Scientific Linux, and CentOS. Globus developers will maintain a Globus repository containing all packages.

GT 5.2 includes the latest versions of all components: GRAM, GridFTP, MyProxy and GSISSH. This latest version of GRAM includes a number of scalability and reliability improvements found from working with Open Science Grid (OSG) that are not in the 5.0 series. GridFTP added support for the DCSC command, which allows the client to specify credentials used to secure the data channel connection. Globus Online utilizes this command for seamless data movement across multiple security domains.

GT 5.2 is protocol and client API compatible with GT 5.0 (e.g. 5.2 clients will work with GT 5.0 services, and visa versa.)

For more information about GT 5.2 visit http://www.globus.org/toolkit/docs/5.2/5.2.0/rn/

Globus Toolkit 4.0.x troubleshooting

Disclosure: this troubleshooting is intended for legacy applications which mandatory need the version 4.0.x of Globus Toolkit. If you don’t have an impelling reason to install that particular version, it is highly recommended that you install the latest version available of Globus Toolkit from its official web site and follow the installation guide of the official documentation.

ERROR service.ReliableFileTransferImpl [main,<init>:76] Unable to setup database driver with pooling.Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

• open /etc/postgresql/X.Y/main/postgresql.conf(where X.Y is current PostgreSQL version) and check that the line beginning with “listen_addresses” is not commented (i.e. the line should not begin with a #) and is set to listen to all addresses, in the following way:

  listen_addresses = '*'

• open /etc/postgresql/X.Y/main/pg_hba.conf” and check that the last line looks like:

  host rftDatabase "globus" "x.x.x.x" 255.255.255.255 md5

  where “x.x.x.x” is your public IP address. If you are using Globus Toolkit on your local machine for testing purposes then using 127.0.0.1 should be fine, although in this case you won’t be able to access Globus services outside your machine;

• check that PostgreSQL is up and running and on which port:

  sudo netstat -tulpn | grep postgres

• PostgreSQL should run on port 5432. The default port number may be automatically changed (usually to 5433) as result of a version upgrade. To change it back to 5432 edit the /etc/postgresql/X.Y/main/postgresql.conf and the stop and start the service (warning: a restart won’t be enough) with:

  sudo service postgresql stop
  sudo service postgresql start

• to check whether PostgreSQL is running properly on the 5432 port run:

  telnet localhost 5432

• the message “telnet: Unable to connect to remote host: Connection refused” would mean either PostgreSQL is not running, or is running on the wrong port. If you get “Connected to localhost.localdomain. Escape character is ‘^]’.” then PostgreSQL is fine.

Globus Toolkit 5.2 beta released

The 5.2 release is protocol and source compatible with Globus Toolkit 5.0.

Major Changes between 5.0 and 5.2:

• Native packaging for linux distributions based on RPM and Debian package managers
• The concept of “flavors” of Globus libraries has been obsoleted
• Elimination of the compile-time distinction between threaded and non-threaded builds. All libraries are built to be thread-safe, but most applications and services will run by default without threads. The GLOBUS_THREAD_MODEL environment variable can be used to select between “none” (nothreads) and “pthreads” event-handling model.
• The toolkit has been reorganized to be compliant with the Filesystem Hierarchy Standard.
• The environment variable GLOBUS_LOCATION is no longer required to be set at runtime (though it is still honored to allow non-native packages to be relocated).
• Shared library versioning to allow different versions of libraries to coexist.
• Simplified configuration: more default values for Globus service configurations (especially GRAM5), more admin tools for interacting with tools (GRAM gatekeeper, audit)
