I have a necessity to read some properties from a file located in local etc/myconfig-config/ folder. I need to give this file path in the command line. I have given it as mentioned below. But there is an error and it displays like 

Error: Could not find or load main class test-tool.jar.

the command given is

java  -cp -DconfigDir=/etc/myconfig-config/ test-tool.jar 
service.ScriptGenerator $clinic_count $client_files_count

can anybody please help me to resolve this.

thanks

    Note that you are wanting to read a property at runtime, not an environment (`System.getProperty("xxx")` vs `System.getenv("xxx")`). – trebor Aug 02 '22 at 01:27

Try giving following command,

java -DconfigDir=/etc/myconfig-config/ -cp test-tool.jar service.ScriptGenerator $clinic_count $client_files_count

Note that the given parameters should be accessed from code as follow:

System.getProperty("configDir")

    Hi, use System.getProperty("configDir") insteadof getenv() method. – Sathish Jun 17 '15 at 12:06

    Thanks a lot Sathish it works.... I ask this question if it is not a disturbance to u. When I run it through IDE the System.getenv("configDir") works fine. But when i run it through terminal using above command the System.getProperty("configDir") working fine.. I cannot think why is this... – Dilan Jun 17 '15 at 12:14

Try this command

export VARNAME='variable-value'

Then run your Java main class from the same command line.

Your command should be like

java  -cp test-tool.jar -DconfigDir=/etc/myconfig-config/ service.ScriptGenerator $clinic_count $client_files_count
