My application is a swing based client communicating to tomcat using spring remoting Http invoker, I want to convert to https.

org.springframework.remoting.RemoteAccessException: Could not access HTTP invoker remote service at [https://localhost:8443/aten_server/metadataservice/MetaDataService-httpinvoker]; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

My client side spring config file is

<bean id="memberDataServiceHttpInvokerProxy" class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
        <property name="serviceUrl" value="#{systemProperties['aten.protocol']}://#{systemProperties['aten.host']}:#{systemProperties['aten.port']}/aten_server/memberdataservice/MemberDataService-httpinvoker"/>
        <property name="serviceInterface" value="com.kantar.server.panel.services.IMemberDataService"/>
        <property name="httpInvokerRequestExecutor">
            <bean class="org.springframework.remoting.httpinvoker.CommonsHttpInvokerRequestExecutor" />
        </property>
</bean>

Please help me to sort out problem

The problem isn't Spring Remoting, it's that the certificate on the server you are accessing is not signed by a CA or trusted certificate - you need to add this certificate to your keystore.

See Adding a foreign server's self-signed certificate to the trusted certificates of my Tomcat for how to do this.

This exception means you use SSL/HTTPS. Please check your certificate, seems it is not installed or invalid
