Looks like I have no options as I have already tried with (catalina.properties), by setting the classpath variable in (setclasspath.bat). I am really wonder why default libraries(catalina_home\lib) also not loading when I change the protocol=com.poc.PocHttp11Protocol in server.xml.
Is there anyway I can force tomcat bootstrap class loader to load external libraries? Can you please suggest me how to override bootstrap class loader to load external libraries? Many thanks in advance. -----Original Message----- From: Christopher Schultz [mailto:ch...@christopherschultz.net] Sent: Friday, May 27, 2016 11:14 PM To: Tomcat Users List Subject: Re: tomcat8.0.33 classpath/classloader issues -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Sanka, On 5/27/16 1:07 PM, Sanka, Ambica wrote: > Do you need to add <Loader delegate="true"/> for your case?
