Can somebody help? I searched on the Internet and I found that there is a file httpcore-xx.jar that must be placed in apache tomcat lib directory. I tried that but it didn't work. I'm using ubuntu 14.04 LTS and eclipse. I also tried to clean my Project and build again. It didn't work. What I'm facing is that the page is loading on the web Browser but when I click on services the previous error comes up. The tutorial I'm trying to implement is http://codeoncloud.blogspot.gr/2012/12/create-java-web-service-in-eclipse_3982.html

Answer 1

I had the same problem and successfully resolved it by copying xmlschema-core-*.jar form axis2-*/lib/ to my_project_root_directory/WebContent/WEB-INF/lib/.
