Test your JKS file easily with java -Djavax.net.ssl.trustStore=your_trust_store.jks TestJKS <url> [<user> <password>]
/*
Test your JKS file easily.
You have created a java JKS trust store file to access a webservice with a certificate, and you want to test if it works?
Some colleagues often test this by deploying the jks to the application server (tomcat, weblogic...), restarting the server and manually running tests,

you can speed up this test by using this simple java program:
> javac TestJKS.java
