kts1021 [http://community.jboss.org/people/kts1021] created the discussion "Re: Upon deploy, JBoss gives me the following error" To view the discussion, visit: http://community.jboss.org/message/585969#585969 -------------------------------------------------------------- Thank you so much! It was my stupidity. Now the project is up and running. However, it gives me this error: [CODE] private Context context = null; private DataSource datasource = null; public void init() throws ServletException {           super.init();           try {                context = new InitialContext();                datasource = (DataSource) context.lookup("java:/comp/env/jdbc/MySqlDS");           } catch (Exception e) {                e.printStackTrace();           } } [/CODE] I am really new to DataSource but Taste CF engine in Mahout requires a datasource. The code above gives me the following error: 22:23:53,062 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/_____].[RecommendServlet]] Servlet.service() for servlet RecommendServlet threw exception: java.lang.IllegalArgumentException: dataSource is null or empty Is something the wrong? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/585969#585969] Start a new discussion in Datasource Configuration at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
