hi romyos
int the context view , choose value as trees and check option button prompt !
You'll have a dialog box where you can initialize your context value

Hello Romyos
1) Define a context variable: filePath in your job, when you delete the file, you should use the context variable as file path in your job.
2) Pass the file path to main method in eclipse, eg:

package excel;
public class Talend {
    public static void main(String[] args) {
        Talend t = new Talend();
        t.test();
    }
    public void test() {
        String[] args = { "--context_param filePath=d:/text.txt" };
        test2.test3_0_1.test3.main(args);
    }
}

About '--context_param filePath=d:/text.txt', in fact we set the value of context dynamically, see 1615.

Hello Romyos
I see that you define a context variable: nom, its data type is File and then set the value of context variable:
--context_param file=c:/test.txt
the correct way is that: the data type should be string and the value of context variable is:
--context_param nom=c:/test.txt //nom is the variable name.
Best regards
