Configuring SSL with No TrustStore and Using Simple Authentication (Username/Password)

I need help to configure activemq ssl without any truststore instead use
username and password for authentication.

I am getting the exception as no trusStore is provided:
Exception in thread "main" javax.jms.JMSException: Could not create
Transport. Reason: java.lang.NullPointerException
at
org.apache.activemq.util.JMSExceptionSupport.create(JMSExceptionSupport.java:35)

org.apache.activemq.ActiveMQSslConnectionFactory.createTransport(ActiveMQSslConnectionFactory.java:123)

org.apache.activemq.ActiveMQConnectionFactory.createActiveMQConnection(ActiveMQConnectionFactory.java:267)
at
org.apache.activemq.ActiveMQConnectionFactory.createActiveMQConnection(ActiveMQConnectionFactory.java:239)
at
org.apache.activemq.ActiveMQConnectionFactory.createConnection(ActiveMQConnectionFactory.java:185)

Below is my configuration:

<transportConnector name="ssl"
uri="ssl://0.0.0.0:61617?maximumConnections=1000橪;wireFormat.maxFrameSize=104857600橪;transport.needClientAuth=true橪;transport.wantClientAuth=false"/>

<sslContext>
<sslContext keyStore="/home/shameem/dev/tools/activemq/broker.ks"
keyStorePassword="password" />
</sslContext>

My Spring configuration:

<bean id="jmsConnectionFactory"
class="org.apache.activemq.ActiveMQSslConnectionFactory">
<property name="brokerURL" value="ssl://localhost:61617" />
<property name="userName" value="admin"/>
<property name="password" value="admin"/>
</bean>
