Irrespective of the system's default settings there are two ways to specify the browser explicitly:

1. Enter a command in the corresponding text field. At the position where a URL is expected, use the string ${URL} as a placeholder. JBoom will replace it by the URL the user has activated.
2. Leave the field empty and install a script named open-url that itself calls the browser. The URL is supplied as a parameter.

The second method should be preferred. If you use it consequently, the same settings can be used on practically all systems.

A sample script open-url which may be used to start Firefox or Opera on Linux can be found in the directory scripts of the jBoom package:

#!/bin/bash # Firefox #exec firefox "$1" # Opera exec opera "$1"

If you want to use it, copy it into one of the directories listed in the search path $PATH. Comment out exactly one of the calls, using the character '#'. If firefox or opera cannot be reached via $PATH, replace the names in the script by absolute paths.

The above applies to the mailer accordingly. Here, too, it is recommended to leave the command field empty and to install a script mailto. Use ${ADDR} as placeholder for the mail address. JBoom will replace it by the address(es) selected by the user.

A sample script mailto for Thunderbird or Opera on Linux can be found in the directory scripts:

#!/bin/bash # Thunderbird #exec thunderbird -compose "to=$1" # Opera exec opera "mailto:$1"

Uncomment the part corresponding to the desired mailer.

For other mailers the script has to be modified in some way. The simplest way to start a mailer which is integrated in a browser (such as Opera) is to use a mailto: URL.
