java - path to trustStore - set property doesn't work?
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");
// Syst开发者_JAVA百科em.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 at ssltest.Main.main(Main.java:15) javax.net.ssl.trustStore is not defined BUILD SUCCESSFUL (total time: 0 seconds)
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
Looks like you have a typo -- "trustStrore" should be "trustStore", i.e.
System.setProperty("javax.net.ssl.trustStrore", "cacerts.jks");
should be:
System.setProperty("javax.net.ssl.trustStore", "cacerts.jks");
Both
-Djavax.net.ssl.trustStore=path/to/trustStore.jks
and
System.setProperty("javax.net.ssl.trustStore", "cacerts.jks");
do the same thing and have no difference working wise. In your case you just have a typo. You have misspelled trustStore
in javax.net.ssl.trustStore.
As pointed out by others, there's a typo in the property.
Another way to check whether JVM is using the configured trustStore is to add the property: -Djavax.net.debug=all
, which will turn on the debug message.
After the app starts, it will print out a message like:
javax.net.ssl|DEBUG|11|parallel-1|2021-04-17 21:25:13.827 CST|TrustStoreManager.java:112|trustStore is: C:/path/to/the/trustStore
Then we can tell whether it's using the one we want or the default one comes with the JDK.

Alternatively, if using javax.net.ssl.trustStore for specifying the location of your truststore does not work ( as it did in my case for two way authentication ), you can also use SSLContextBuilder as shown in the example below. This example also includes how to create a httpclient as well to show how the SSL builder would work.
SSLContextBuilder sslcontextbuilder = SSLContexts.custom();
sslcontextbuilder.loadTrustMaterial(
new File("C:\\path to\\truststore.jks"), //path to jks file
"password".toCharArray(), //enters in the truststore password for use
new TrustSelfSignedStrategy() //will trust own CA and all self-signed certs
);
SSLContext sslcontext = sslcontextbuilder.build(); //load trust store
SSLConnectionSocketFactory sslsockfac = new SSLConnectionSocketFactory(sslcontext,new String[] { "TLSv1" },null,SSLConnectionSocketFactory.getDefaultHostnameVerifier());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsockfac).build(); //sets up a httpclient for use with ssl socket factory
try {
HttpGet httpget = new HttpGet("https://localhost:8443"); //I had a tomcat server running on localhost which required the client to have their trust cert
System.out.println("Executing request " + httpget.getRequestLine());
CloseableHttpResponse response = httpclient.execute(httpget);
try {
HttpEntity entity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
EntityUtils.consume(entity);
} finally {
response.close();
}
} finally {
httpclient.close();
}
