How to lookup JNDI resources on WebLogic?

Question

I deployed a legacy application on WebLogic 11g. The application has the following code:

 Context context = new InitialContext();
 dataSource = (javax.sql.Da         


        

Answer 1

I just had to update legacy Weblogic 8 app to use a data-source instead of hard-coded JDBC string. Datasource JNDI name on the configuration tab in the Weblogic admin showed: "weblogic.jdbc.ESdatasource", below are two ways that worked:

      Context ctx = new InitialContext();
      DataSource dataSource;

      try {
        dataSource = (DataSource) ctx.lookup("weblogic.jdbc.ESdatasource");
        response.getWriter().println("A " +dataSource);
      }catch(Exception e) {
        response.getWriter().println("A " + e.getMessage() + e.getCause());
      }

      //or

      try {
        dataSource = (DataSource) ctx.lookup("weblogic/jdbc/ESdatasource");
        response.getWriter().println("F "+dataSource);
      }catch(Exception e) {
        response.getWriter().println("F " + e.getMessage() + e.getCause());
      }

      //use your datasource
      conn = datasource.getConnection();

That's all folks. No passwords and initial context factory needed from the inside of Weblogic app.
