Hi, I am having difficulty in defining the web app name property. I think I am doing some thing wrong when specifying the value for property name from the class implementing the PropertyDefiner interface. My configuration for property definition looks like: *<define name="WEBAPP" class="org.akaza.openclinica.control.WebAppNamePropertyDefiner"> <aProperty>webAppProperty</aProperty> </define>* and the class implementing PropertyDefiner interface looks like: *import ch.qos.logback.core.PropertyDefinerBase; /** * @author pgawade Class defined to return the web application name */ public class WebAppNamePropertyDefiner extends PropertyDefinerBase { static String webAppProperty; public WebAppNamePropertyDefiner() { // super(); } public WebAppNamePropertyDefiner(String webAppName) { if (webAppProperty == null) { webAppProperty = webAppName; } } public String getPropertyValue() { return webAppProperty; } }* I am not clear about what should me mentioned for element <aProperty>. Or it should element name be actual property name? I did not get any example of this on internet. Any inputs? Is it possible to define multiple properties in the same class *WebAppNamePropertyDefiner *or there needs to be one class per property definition? On a side note, I realized that probably I can put the web application name in MDC context and use that variable in the configuration.

Yes, you can define properties dynamically. See http://logback.qos.ch/manual/configuration.html#definingPropsOnTheFly

Hi,

Can I use my Spring web application name in the logback configuration dynamically? I know logback can read from properties file specified under <property> or it can read from the system variables but is it possible to use some dynamic data like web application name in the configuration?

Thanks, Pradnya
