2 way SSL authentication not working using Apache httpclient: JAVA

2 way SSL authentication in JAVA using apache httpclient (certificates are self signed) not working for me. I am getting Bad cert fatal error from Server. I looked at captured pcap in wireshark and I see client is not sending it’s certificate. Here is what I have done so far, would really appreciate any help.

Generated keyStore and trustStore using keytool:

keytool -importcert -file /home/foo/server.crt -alias server_cert -keystore /home/foo/ca_truststore.jks -noprompt -storepass foo
openssl pkcs12 -export -in /home/foo/client.crt -inkey /home/foo/client_private_key.pem -out /home/foo/client.p12 -name client_cert -passout pass:foo
keytool -importkeystore -deststorepass foo -destkeypass foo -destkeystore /home/foo/client_keystore.jks -srckeystore /home/foo/client.p12 -srcstoretype PKCS12 -srcstorepass foo -alias client_cert

Starting tomcat7 with these JVM settings

JAVA_OPTS="-Djava.awt.headless=true -Xmx512m -XX:+UseConcMarkSweepGC -Djavax.net.ssl.trustStore=/home/foo/ca_truststore.jks -Djavax.net.ssl.trustStorePassword=foo -Djavax.net.ssl.trustStoreType=JKS -Djavax.net.ssl.keyStore=/home/foo/client_keystore.jks -Djavax.net.ssl.keyStorePassword=foo -Djavax.net.ssl.keyStoreType=JKS"

In my JAVA application code I queried the System property for trustStore and keyStore and I can see that they are same as the values I set above.

Here is my code:

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

CloseableHttpClient httpclient = HttpClients.createDefault();
String url = "https://x.x.x.x";
String data = "something to send";
String authStringEnc = "This is Base 64 encoded userid:pwd"; 
try {

    HttpPost request = new HttpPost(url);

    StringEntity params = new StringEntity(data.toString());

    request.setHeader("Authorization", "Basic " + authStringEnc);
    request.addHeader("content-type", "application/json");
    request.addHeader("Accept","application/json");
    request.setEntity(params);

    CloseableHttpResponse response = httpclient.execute(request);

    try {
        HttpEntity entity = response.getEntity();
        if (entity != null) {
            System.out.println("Response content length: " + entity.getContentLength());
        }
        EntityUtils.consume(entity);
    } finally {
        response.close();
    }
}

Exception that I get:
