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

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")

Try this command

export VARNAME='variable-value'

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