Servlet can not find classes in ear file, only in system classpath.

Question

Hi,
          My servlet "DataServlet" is included in ear/war file.
          When I try to reach it:
          http://www.mysite.com/DataServlet
          Servlet starts execute doPost() and throw Exception ClassNotFound.
          All classes inculuded in ear files and all jsp working fine.
          It works like standalone servlet and not as part of web application.
          Maybe, there is problem in context root?
          web.xml configuration:
          <servlet-mapping>
          <servlet-name>
          DataServlet
          </servlet-name>
          <url-pattern>
          /DataServlet
          </url-pattern>
          </servlet-mapping>
          application.xml configuration:
          <web>
          <web-uri>data.war</web-uri>
          <context-root>data</context-root>
          </web>
          Thanks,
          Oleg.

Answer 1

Is the ClassNotFoundException on the DataServlet class, or a class the DataServlet class is trying to use?
          Did you try <http://www.mysite.com/data/DataServlet>?
          I would recommend you always define your classes in packages, as opposed to the default package, which you appear to be using. You'll run into problems down the line if you use the default package.
