    Integrating web application

    innovate Newbie

      Hi,

      I like to integrate a web application into Nukes. The web application is built using the spring framework. There is a dispatcher servlet running which controls the application flow. What is the best or which solution is possible?

      1) Modify web.xml, so URL's with a pattern /billing are redirected to a particular web application.

      2) Write a module which processes the request and uses process(...) to include the Servlet response into the module.

      The web application should be thightly integrated into Nukes, a particular user should not see that another web application is running.

          I have a similar situation that I'm trying to figure out and would be interested in this as well. Specifically, I would like to know how to integrate authentication so that when people authenticate to nukes, they are also authenticated to other webapps using the same credentials. Our existing applications use JAAS for authentication. Is there a way to propagate a nukes login to another app via JAAS?

          Thanks,
          gary.

            Same problem here. I am trying to integrate an existing JSF application with nukes, and specifically some of the login front-end, as well as newsgroups, etc. modules.

            I am trying to use a module to proxy to the JSPs, but I am struggling with that. Anyway someone could post further details than what's available on the Wikis?

            Thanks,
            Serge

              No takers on this? Somebody, somewhere has to have done this before. It's a pretty critical subject IMO.

              The last thing I want is to have a site that is like every other PHP/Perl site out there where you have to login to all the cobbled together applications because there is no common authentication system.

              Last I knew, Nukes did not use JAAS. Is that still the case? If not, any plans to make Nukes use JAAS?

              gary.

                I looked at it and decided to wait for the port of Nukes to a more recent JBoss to use a class of JBossSX that doesn't exist in the JBoss version we support.

                That new class will offer more flexibility. The problem is that we want an easy install process for default behavior.

                We don't want users to mess with:
                $JBOSS_HOME/server/default/conf/login-config.xml

                Instead JAAS configuration should be setup at deployment, it will be an easy fix as soon as we support JBoss 3.2.4 and above.

                  I created a .sar file for one of my applications that dynamically adds it's security domain to JBoss without mucking with login-config.xml. It was extremely easy to do and took about an hour. If you are interested, I can post further info. I'd love to see this feature implemented earlier rather than later.

                  FYI, my solution works on 3.2.1. I've not tried it on newer versions, but I'd think it should work.

                    I am interested, please tell me more on how you did here on the forum or you can email me if you want to add some code at users.sourceforge.net

                      I can't take full credit for all of the code because I found the concept and most of the code via google. But, I can't locate the original source it seems. I've tried some searches but no luck so far. If I can find the URL for where I found the original code, I will post it to give credit to the author.

                        I still want to stick with DynamicLoginConfig as it's fully integrated with JBoss:
                        http://www.jboss.org/wiki/Wiki.jsp?page=DynamicLoginConfig

                        I understand the drawback is that Nukes won't be compatible with JBoss 3.2.3 and lower.

                        Julien the project leader will decide.

                        If there is more to say about design we should use the dev forum.

                        Thanks for sharing your code.

                          Ok. I had found the DynamicLoginConfig, but I'm not able to use the supported versions of JBoss yet, so needed something more immediate. If the work to make Nukes run on a late model JBoss will take considerable effort, the 1 or 2 hours of effort to implement my code would probably be worth it. It can always be deprecated and may get the project to support JAAS that much sooner.

                          Just my thoughts.

                            the code you are using is more or less directly out of the examples included w/ the jboss admin book. (at least w/ the paid subscription)

                            if you're in a hurry to get this done, there's nothing wrong w/ deploying the code yourself and then migrating once > 3.2.4 is supported. you're still going to need a deployment descriptor in order to hook up the secuirty configuration.

                            i already have this code written and more or less readily at hand. if you want it, pls let me know and i'll send it to you.

                              What is it that your code will accomplish? Is it code that integrates nukes with JAAS? My end goal is to have nukes integrated with other J2EE applications. If your code will help in this regard, then I guess I'm interested.

                              So far, I've not really found any other options for doing this.

                                no - it's just the code that you already pasted, but in .java file form.
