Setting application/system properties for WildFly 10

You can set application/system properties on Wildfly 10 (it should be the same with previous version of Wildfly). In this particular case we will set the property for the folder that will be used by logback to save logs.

Below is the logback configuration.

We need to set the application variable application.logs.dir so that logback can use the correct folder. To achieve this we add the system-properties in the configuration file, in our case standalone.xml. This should be immediately after the extension tag.

Don’t forget to restart the application server for the changes to take effect.

Download Oracle JDK using wget

We are all used to downloading the JDK from Oracle using the browser. You will have to accept the licence to proceed with the download.

This makes it tricky to download on a Linux installation without or you don’t have access to its GUI. Trying to use wget will download an HTML page insisting you accept the licence. There are a couple of ways to get round ‘Accept Licence’ issue including the plain old download on local machine and upload to the remote machine. The simplest I got was to add the authentication parameter that’s used by the download server to verify if you have accepted the license to the JDK download URL used by wget.

The solution to get the precious AuthParam cookie, in this post I use Google Chrome to retrieve it. On the download page right click and select “Inspect Element”. Select the “Network” tab on the debugging window. After accepting the licence on the browser click on the file to download it. Quickly cancel the download and check the Network output. Right click the last result and copy the link.

wget will download the JDK.


Installing Postgres on Ubuntu 10.10

Installing postgres on Ubuntu 10.10

sudo apt-get install postgres pgadmin3

Now try to connect to postgres Applications > Programming > pgAdmin III

You will get the error below.

Postgres login error

It turns out Postgres setup is not complete yet. In MySQL you will be ready to go, root with an empty password, certainly not good for security

Switch to postgres and set the password

sipatha@lpt1:~$ sudo -u postgres psql
psql (8.4.5)
Type "help" for help.

postgres=# \password postgres
Enter new password:
Enter it again:
postgres=# \q

Now try again logging in using pgAdmin III

We good to go!
