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.
Thanks for your help
Ravi

Hello Ravi,
This is quite strange because for some name 'n', the JNDI lookup code in
logback essentially does InitialContext().lookup(n) the same code that
seems to work for you. 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?
