Download the libraries
Download the following libraries into a folder of your system:
Apache XML-RPC Apache Jakarta Commons
Since the server at baco computer uses an older version, if you are planing on accessing it server, you should download this version of SDAS Core Libraries and Client:
SDAS Core Libraries SDAS Client
If you are using a different server, download these instead:
SDAS Core Libraries SDAS Client
Set the classpath
Add all of the previous libraries to your system classpath. Use the matlab static path. More information at the matlab documentation site. If your are unable to set the static path on your computer you can use the dynamic path.
Test the java connection
...
You should use the latestlast version (at least 1.5) of the Sun Java. If your copy of MatLab has a more recent version of Java you can skip this step.
First you have to find out where is your java home located. To avoid errors, download and run this utility. The value returned by the utility is the MATLAB_JAVA value.
NOTE: Each time you change system properties, you have to restart MatLab
Now you have to set the MATLAB_JAVA as a system variable:
Open the windows System Properties (right - click on My Computer or go to the Control Panel)
Select the tab Advanced
Click on Environment Variables...
In the system variables click New...
The Variable name is: MATLAB_JAVA
In the value field (supposing you have the java_home in the libraries in C:\Program Files\java\jdk1.5.0_04\jre) enter the following value: C:\Program Files\java\jdk1.5.0_04\jre
Supposing you have the java_home in /opt/jdk1.5.0_04/jre/ :
export MATLAB_JAVA="/opt/jdk1.5.0_04/jre/"
