Can't get initialized static variables from servlet
Summary: Can't get initialized static variables from servlet
Product: Tomcat 4
Version: 4.1.12
Platform: PC
OS/Version: Linux
Status: NEW
Severity: Normal
Priority: Other
Component: Unknown
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: dinigor@mail.ru
In my web application I have several static variables and try to initialize
them using ServletContextListener defined in web.xml.
In log file I see that variables were properly initialized.
But when I send requests to servlet or JSP I get NPE, becase that variables is
null.
Then I stop TomCat and see in files that variables were correctly finilized!
So, they lived somewhere, but I could not get them. Tomcat server is one JVM.
I checked classloader in several cases and got the same class
org.apache.catalina.loader.WebappClassLoader.
I got the same problem using init() method in servlet together with
load-on-startup.
It looks like for one web application defined in one context I got two
different ServletContexts when try to initialize application using
ServletContextListener or init()+load-on-startup. First contains init.
parameters from both server.xml & web.xml, second only from web.xml.
In this case I can't pass initialized variales to servlet using
ServletContext arguments.
First I got the problem in 4.0.2.
