Hi Ceki, I have logback-core, classic, janino, commons-compiler jar files located under WEB-INF/lib folder, and the logback.xml is under WEB-INF/classes. In the console, the logback logs appear ahead of the application specific servlet and filter (from web.xml) init method System out statements. I have modified the InsertFromJNDIAction class to print its classloader and did the same for servlet and filter init methods too. All of them printed the same class loader name. So, I added, ClassLoader loader = Thread.currentThread().getContextClassLoader(); System.out.println("InsertFromJNDIAction "+loader.getClass().getName()+" "+loader.hashCode()+" "+loader.toString()); org.apache.catalina.loader.WebappClassLoader 1024180126 WebappClassLoader delegate: false repositories: /WEB-INF/classes/ ----------> Parent Classloader: org.apache.catalina.loader.StandardClassLoader@46c837cd The jndi context lookup is successful in servlet and filter init methods to print the env-entry-value. Logback still threw the error for lookup.

Could the discrepency be attributed to differences in the class loader for logback and the servlet code which is able to correctly read the JNDI entries? Where are the logback classes located on your application's class path? -- Ceki On 06/06/2011 10:25 PM, Ravikanth Gangarapu wrote:
Hi,
I am using logback-classic (0.9.28) for a web application running on tomcat 5.5.
I am trying to read the JNDI env entry values using the <insertFromJNDI env-entry-name="java:comp/env/stderr-logging" as="stdErrLogging" /> tag in the logback.xml file.
I have lots of env entry values that can be read from META-INF/context.xml file. For this specific example, my context.xml file has this.
<context>
..
<Environment name="stderr-logging" type="java.lang.String" value="true"/>
..
But, this insertFromJNDI tags always says the entry value is null or empty. However, Once I am in a servlet code, new InitialContext().lookup("java:comp/env/stderr-logging") retrieves the correct value from context xml file.
I looked in the JNDIUtil class from ch.qos.logback.classic.util package and the code throws error saying "javax.naming.NameNotFoundException: Name java:comp is not bound in this Context".
Would somebody know how to read the environment entry values from the META-INF/context.xml file ?
Thanks for help
Ravi
