package com.bar.foo.utils; import java.util.hashmap; import java.util.map; import java.util.properties; import org.springframework.beans.factory.config.configurablelistablebeanfactory; import org.springframework.beans.factory.config.propertyplaceholderconfigurer; public class propertiesutil extends propertyplaceholderconfigurer { private static map<string, string> propertiesmap = new hashmap<string, string>(); // default in propertyplaceholderconfigurer private int springsystempropertiesmode = system_properties_mode_fallback; /** * workaround: propertyplaceholderconfigurer.systempropertiesmode not * straight accessible */ @override public void setsystempropertiesmode(int systempropertiesmode) { super.setsystempropertiesmode(systempropertiesmode); springsystempropertiesmode = systempropertiesmode; } @override protected void processproperties(configurablelistablebeanfactory beanfactory, properties props) { super.processproperties(beanfactory, props); (object key : props.keyset()) { string keystr = key.tostring(); string valuestr = resolveplaceholder(keystr, props, springsystempropertiesmode); propertiesmap.put(keystr, valuestr); } } public static string getproperty(string name) { homecoming propertiesmap.get(name); } }

found solution. turns out web.xml setup wrong. had tried right syntax, bad configuration of tomcat server caused error (noclassdeffounderror: javax.servlet.servletexception) deploying project on different server instance seemed fix. right configuration below:

add web.xml:

<servlet> <servlet-name>appservlet</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <init-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:applicationcontext.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>
