My Printer's Gone!

I was missing my printer. Turns out I could just add it in the Printer Settings in Linux.

I don't know why it was suddenly missing, though.

Perhaps it happened during an upgrade of Fedora Core.

I know I installed all the required drivers some time ago.

Oh well. I thought it was something serious. It's nice to be disappointed.

Installing Printer Driver in Fedora for Epson ET-3750

Just some information in case I need to reinstall the drivers sometime in the future.

The following is in my log:

[ 650.114340] usb 2-1.8: new high-speed USB device number 5 using ehci-pci
[ 650.196888] usb 2-1.8: New USB device found, idVendor=04b8, idProduct=1130, bcdDevice= 1.00

[ 650.245915] usbcore: registered new interface driver usblp

I found some information at [1].

[root@mrbear Downloads]# dnf install lsb

Lsb is required, or it starts complaining when trying to install the rpm packages.

rpm -i epson-inkjet-printer-escpr2-1.1.25-1lsb3.2.x86_64.rpm
rpm -i epson-printer-utility-1.1.1-1lsb3.2.x86_64.rpm

Via LPADMIN

# lpadmin -p [PRINTER_NAME] -v [DEVICE_URI] -P [PPD_FILE] -E

# lpadmin -p et3750 -v "usb://EPSON/ET-3750%20Series?serial=583445553036353185&interface=1" -P /opt/epson-stuff-this-and-that-en.ppd.gz -E

Via Webbrowser

This works if you have attached the printer via USB cable.

You can access CUPS via a webbrowser at http://localhost:631.

As administrator ask for "Add printer".

The list shows EPSON ET-3750 Series (EPSON ET-3750 Series).

Name: EPSON_ET-3750_Series
Description: EPSON ET-3750 Series

Adding MariaDB JDBC Connector to Paraya 5

It's as easy as pie.

start Payara
$ cd ~/payara5/bin
$ ./asadmin start-domain
Waiting for domain1 to start ...............
Successfully started the domain : domain1
domain Location: /home/mrbear/payara5/glassfish/domains/domain1
Log File: /home/mrbear/payara5/glassfish/domains/domain1/logs/server.log
Admin Port: 4848
Command start-domain executed successfully.
install the database driver
$ ./asadmin add-library /home/mrbear/software/mariadb-java-client-2.3.0.jar
Command add-library executed successfully.

or try:
$ cp ~/Downloads/mariadb-java-client-2.3.0.jar ~/payara5/glassfish/domains/domain1/lib

The last part will probably require a payara application server reboot, though.
connect to http://localhost:4848
surf to Resources -> JDBC -> JDBC Connection Pools
Create a new one
Settings:

Pool name [obvious]

Resource Type javax.sql.DataSource

Datasource classname org.mariadb.jdbc.MariaDbDataSource

Leave the rest as default.
Define the following additional properties:
Name Value

serverName localhost

URL jdbc:mariadb://localhost:3306/mmud

databaseName mmud

user username

password itsasecret
Try the "Ping" button to verify that the connection is established.
surf to Resources -> JDBC -> JDBC Resources
Create a new one
Settings:
Name Value

JNDI Name this is the name as the resource is defined in your application

Pool Name the pool defined previously, it's a dropdown which is convenient.
Press finish or OK or something
Done!

Name	Value
serverName	localhost
URL	jdbc:mariadb://localhost:3306/mmud
databaseName	mmud
user	username

Adding MariaDB JDBC Connector to Wildfly 14

install the database driver as a module

create directory WILDFLY_HOME/modules/com/mariadb/main
$ mkdir -p modules/com/mariadb/main
copy database driver into that one
$ cp ~/Downloads/mariadb-java-client-2.3.0.jar .
Create the file module.xml in the same folder with the following content:
<module xmlns="urn:jboss:module:1.3" name="com.mariadb">
    <resources>
        <resource-root path="mariadb-java-client-2.3.0.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
    </dependencies>
</module>

start Wildfly
$ cd $WILDFLY_HOME/bin
$ ./standalone.sh
connect to http://localhost:9990/error/index.html
run ./add-user.sh
[mrbear@localhost bin]$ ./add-user.sh

What type of user do you wish to add?
a) Management User (mgmt-users.properties)
b) Application User (application-users.properties)
(a): a

Enter the details of the new user to add.
