Java, already installed.

Here is the procedure to install JChemPaint:

• JChemPaint is distributed as a JAR archive, ready to execute. Create a folder under /home/bioubuntu to put the archive in and move this folder to /opt/bio/sources.

<code bash>
% mkdir jchempaint-3.1.2
% mv jchempaint-3.1.2.jar jchempaint-3.1.2
% sudo mv jchempaint-3.1.2 /opt/bio/sources

</code>

• This folder should belong to root and its permissions set to 755.

% sudo chown -R root:root /opt/bio/sources/jchempaint-3.1.2
% sudo chmod 755 /opt/bio/sources/jchempaint-3.1.2

• Once you are in /opt/bio/sources/jchempaint, create a small startup script to failitate the job:

% sudo nano runJChemPaint

• Put this code in it:

#!/bin/bash
export JCP_HOME=/opt/bio/sources/jchempaint-3.1.2
java -Xmx512m -jar $JCP_HOME/jchempaint-3.1.2.jar

• You need to make this script executable and available to all:

% sudo chmod ugo+x runJChemPaint
% sudo ln -s /opt/bio/sources/jchempaint-3.1.2/runJChemPaint /usr/local/bin/runJChemPaint

• To add JChemPaint to the Impilo application menu, you need to edit the Xfce4 configuration file:
  • More to come…

• To use JChemPaint from the command line:

% runJChemPaint
