How to set system property values in NetBeans?

问题:

I 'm following a tutorial about JAAS Authentication here and when it shows how to run the example code, says that the compiled class should be launched with a standard option of Java launcher which is -Djava.security.auth.login.config==sample_jaas.config . In this way a system property will be set:

java -Djava.security.auth.login.config==sample_jaas.config sample.SampleAcn

I did it with this way, but now I want to run the code in NetBeans too. Since NetBeans use Ant I think specifying these options may be different. I looked at the options menus in NetBeans but didn't find anything. How could I set this property when running with NetBeans?

回答1:

• You can right click on the project, and select Properties.

• Click on Run category and insert you configuration in VM Options

• For instance, in your case, paste: -Djava.security.auth.login.config=sample_jaas.config

You've to use = not ==.
