Set Java class parameter

I am trying to use a custom java driver( UcanAccess ) to connect to a Access database. I was able to add the java file and its dependencies to my java path. However, the driver requires me to set a java parameter with the path to the driver. Without setting the path I get the following error message:The UCANACCESS_HOME system variable isn't defined: it should be: -DUCANACCESS_HOME=<your path to the UCanAccess-3.x.x-bin folder>. Does anyone know how to set this java parameter ?

Hi Ritesh,

Are you trying to connect to Access using MATLAB, and are trying to set the system variable in MATLAB?

In general, you could pass the required argument as a VM argument to a Java application:

If connecting through MATLAB, you could try placing the -D directive in the java.opts file based on the example below:

Hope this helps!
