sendRedirect method of Java ServletRequest class breaks flow on using Oracle HTTP Server

User_5S8POJun 23 2022 — edited Jun 27 2022

Hi All,
We have 2 war files deployed on standalone JVM in Weblogic 12.2.1.3 and request is routed using ProxyPass module on Apache 2.4.33.
Application 1 with context root (NAS) uses sendRedirect method in servlet to access module in Application 2 with context root(PTS) which is also deployed on the same JVM & port.
The application module is accessible & works fine when Apache HTTP server is used as proxy on Oracle Weblogic Server.
The same application module fails with Page not found error when Oracle HTTP Server is used as proxy server. (Application fails with mod_wl plugin & ProxyPass). Weblogic plugin is enabled on Weblogic.
sendRedirect method route request back to client browser. Can we use RequestDispacther method to route request to other servlet deployed in seperate war file but on the same server.
Any pointers or examples to achieve the same would be helpful.

Horrible. All of it.

Using an outdated Web Toolkit API.

Not using bind variables, leaving open a giant security hole.

And using the same magnificent reasoning that made your code so horrible, and applied it to posting a PL/SQL question in a forum that EXPLICITLY states No Product Questions.

You can use owa_util.bind_variables to open a cursor for a query string with multiple binds and pass the resulting cursor to owa_util.listprint, but beware of implicit conversions, e.g.

DECLARE
  PROCEDURE init_owa
  IS
      l_names owa.vc_arr;
      l_values owa.vc_arr;
  BEGIN
      l_names (1) := 'DUMMY_NAME';
      l_values (1) := 'DUMMY_VALUE';
      owa.init_cgi_env (
        num_params => l_names.COUNT,
        param_name => l_names,
        param_val => l_values);
  END init_owa;
  PROCEDURE dump_owa
  IS
      l_page htp.htbuf_arr;
      l_rows INTEGER := 99999999;
  BEGIN
      owa.get_page (
        thepage => l_page,
        irows => l_rows);
      FOR i IN 1 .. l_rows LOOP
        dbms_output.put_line (l_page (i));
      END LOOP;
  END dump_owa;
BEGIN
  init_owa;
  DECLARE
      p_deptno dept.deptno%TYPE := 10;
  BEGIN
      owa_util.listprint (
        p_thecursor =>
            owa_util.bind_variables (
              thequery =>
                  q'{SELECT DISTINCT job, job || ' - ' || INITCAP (job), NULL }' ||
                  q'{FROM emp WHERE deptno = TO_NUMBER (:b_deptno)}',
              bv1name => 'b_deptno',
              bv1value => TO_CHAR (p_deptno)),
        p_cname => 'p_cname',
        p_nsize => 99,
        p_multiple => TRUE);
  END;
  dump_owa;
END;

LOL well thanks for that. Actual feedback on the issue would have been nice..But I guess thats constructive criticism....or just being a d!ck...idk...especially that early in the morning too...amazing.

-- Doing the best with what I've got

-- You really could have just suggested  using owa_util.bind_variables as @padders suggested.

-- Yea I figured it was the wrong area to post in. I did search around for the correct spot but the site is a little tough to navigate ( I don't spend my entire day on here )

But thanks for that..It did make me laugh

Sorry about that

Thanks for the help. I'll take a look and dissect. This should work, especially utilizing ow_util.bind_variables function.

Thanks a lot
