Hi, As I wrote I'm placing the extension jar in "C:\apache-tomcat-7.0.25\ext". I tried the following: I specified "C:\apache-tomcat-7.0.25\lib" as value for "catalina.ext.dirs" property and now the web application is working.
But then I have two questions: - Do we need "catalina.ext.dirs" at all if we can use only Tomcat's classpath dirs? Let's look through them instead of introducing additional property. - Does this mean that we can use only Tomcat's classpath dirs and we cannot specify a custom directory for these extensions?
