package com.mycompany.client;

public class MyProvider implements com.rsa.command.ConnectionInfoProvider {

      private String propertiesFile = null;   //using a file to store the properties

      public void setPropertiesFile(String propertiesFile) {    //invoked by Spring framework if specified in bean definition

            this.propertiesFile = propertiesFile;

      }

      public String getStringValue(String key) {

            String prop = null;

            //retrieve (and decrypt) the specified property from propertiesFile

            return prop;

      }

The bean definition in CommandClientAppContextOverrides.xml would then be:

...

<!--

| Override the definition of ConnectionInfoProvider

|-->

<bean name="ConnectionInfoProvider"

class="com.mycompany.client.MyProvider"

lazy-init="false">

<property name="propertiesFile" value="config.properties"/>

</bean>
