You need to configuring JSSE System Properties, specifically point to client certificate store.

Via command line:

java -Djavax.net.ssl.trustStore=truststores/client.ts com.progress.Client

or via Java code:

import java.util.Properties;
    ...
    Properties systemProps = System.getProperties();
    systemProps.put("javax.net.ssl.keyStorePassword","passwordForKeystore");
    systemProps.put("javax.net.ssl.keyStore","pathToKeystore.ks");
    systemProps.put("javax.net.ssl.trustStore", "pathToTruststore.ts");
    systemProps.put("javax.net.ssl.trustStorePassword","passwordForTrustStore");
    System.setProperties(systemProps);
    ...
