You could put the name of the file into the war and keep the file itself outside it

eg

C:/etc/myproject/content is the file system and metadata is the properties file. My local is en_US so there is a file named metadata_en_US.properties and metadata.properties
 
<bean id="metadataMessageSource"
class="org.springframework.context.support.ReloadableReso urceBundleMessageSource">
<property name="basename"
value="file:C:/etc/myproject/content/metadata" />
<property name="cacheSeconds" value="1" />
</bean>
 
and 
 
<bean id="metadataMessageSource"
class="org.springframework.context.support.ReloadableReso urceBundleMessageSource">
<property name="basename"
value="C:/etc/myproject/content/metadata" />
<property name="cacheSeconds" value="1" />
</bean>

Thanks dravidnsr, how do i refer the file in the application. Now i do it like this,

private static String DATAACCESS_RESOURCE_NAME = "config/dataaccess.properties";try {
                        prop.load(DataConnection.class
                                    .getClassLoader().getResourceAsStream(DATAACCESS_RESOURCE_NAME));
                  } catch (Exception e) {
                        throw new PVCDAOException("ConfigFileMissingException" +
                                    DATAACCESS_RESOURCE_NAME, e);
                  }

you need to use a FileInputStream instead of using the classloader

private static String DATAACCESS_RESOURCE_NAME = "/etc/config/dataaccess.properties";
try {
                        prop.load(new FileInputStream(DATAACCESS_RESOURCE_NAME));
                  } catch (Exception e) {
                        throw new PVCDAOException("ConfigFileMissingException" +
                                    DATAACCESS_RESOURCE_NAME, e);
                  }

I forgot to add that your initial comments about using web.xml were correct. See
