Question

I’ve setup a self-signed certificate to test an ssl java connection – however, it is refusing to locate the java trustStore. I’ve saved copies of it in /Java/jre6/lib/security in addition to the folder where the classes are compiled to (im using netbeans) and also to /java/jre6/bin
none of the above appears to work, because when i run the following – trustStore = null.

public class ShowTrustStore {

    public static void main(String[] args) {

        System.setProperty("javax.net.ssl.keyStore", "keystore.jks");
        System.setProperty("javax.net.ssl.trustStrore", "cacerts.jks");
        System.setProperty("javax.net.ssl.keyStorePassword", "changeit");



        String trustStore = System.getProperty("javax.net.ssl.trustStore");
        if (trustStore == null) {
            System.out.println("javax.net.ssl.trustStore is not defined");
        } else {
            System.out.println("javax.net.ssl.trustStore = " + trustStore);
        }
    }
}

how to set the path correctly?

**********UPDATE************
Using the getFile() method and some more debug data:

package ssltest;

public class Main {

    public static void main(String[] args) {

//        System.setProperty("javax.net.ssl.keyStore", "/keystore.jks");
//        System.setProperty("javax.net.ssl.trustStrore", "/java.home/cacerts.jks");
//        System.setProperty("javax.net.ssl.keyStorePassword", "changeit");
//        System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

        try {
            Main.class.getResource("trustStore.jks").getFile();
        } catch (Exception e) {
            e.printStackTrace();
        }

        String trustStore = System.getProperty("javax.net.ssl.trustStore");

        if (trustStore == null) {
            String storeLoc;
            storeLoc = System.getProperty("java.class.path");
            System.out.println("classpath: " + storeLoc);
        }

        trustStore = System.getProperty("javax.net.ssl.trustStore");
        if (trustStore == null) {
            System.out.println("javax.net.ssl.trustStore is not defined");
        } else {
            System.out.println("javax.net.ssl.trustStore = " + trustStore);
        }
    }
}

run:

java.lang.NullPointerException
classpath: C:\Users\Main\Documents\NetBeansProjects\sslTest\build\classes;C:\Users\Main\Documents\NetBeansProjects\sslTest\src

Answer 1

You have a typo – it is trustStore.

Apart from setting the variables with System.setProperty(..), you can also use

-Djavax.net.ssl.keyStore=path/to/keystore.jks
