One way to do it is to add your external config folder to the classpath of the java process  That s how I ve often done it in the past

This blog can help you  The trick is to use SpEL  spring expression language  to read the system properties like user home  to read user home directory using SpEL you could use    systemProperties  user home    expression inside your bean elements  For example to access your properties file stored in your home directory you could use the following in your PropertyPlaceholderConfigurer  it worked for me     lt bean id  propertyConfigurer  class  org springframework beans factory config PropertyPlaceholderConfigurer  gt       lt property name  locations  gt           lt value gt file    systemProperties  user home    ur folder settings properties lt  value gt       lt  property gt   lt  bean gt

You can try something like this    lt context property-placeholder          location    ext properties dir classpath   servlet properties    gt    And define ext properties dir property in your application server   jvm  otherwise the default properties location  classpath     i e   classes dir of  jar or  war  would be used   -Dext properties dir file  usr local etc    BTW  very useful blog post
