If your JAR file is in CATALINA_HOME/lib, then the classes in it should be available. Something definitely sounds broken in your installation. Do you have any JAR files that appear in multiple places within the ClassLoader hierarchy? It sounds like you've been changing every setting you can find, so perhaps you have broken everything. > Is there anyway I can force tomcat bootstrap class loader to load > external libraries? Tomcat's bootstrap library should not need any external libraries. It only needs bootstrap.jar and tomcat-juli.jar to get started. After that, the server ClassLoader is created and should have access to all classes in JAR files in CATALINA_BASE/lib and CATALINA_HOME/lib > Can you please suggest me how to override bootstrap class loader > to load external libraries? Put your JAR file in CATALINA_BASE/lib and nothing else. This works on an otherwise unmodified installation of Tomcat, with all versions of Tomcat since 6.0. - -chris > -----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 > > Sanka, > > On 5/27/16 1:07 PM, Sanka, Ambica wrote: >> Do you need to add <Loader delegate="true"/> for your case? >> Please check >> http://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html > > This is almost never the right solution to a problem. > > -chris > >> -----Original Message----- From: Venkata Reddy P >> [mailto:venkata.re...@trianz.com] Sent: Friday, May 27, 2016 1:02 >> PM To: Tomcat Users List <users@tomcat.apache.org> Subject: RE: >> tomcat8.0.33 classpath/classloader issues > >> Many thanks Ambica for the detailed information.
