    Incompatibility among related classes?

    Euler Oliveira Newbie

      Dear colleagues, please help me with this problem:

      I had already put a small JSFUnit test to work, following the instructions in http://labs.jboss.com/jsfunit/gettingstarted.html. I did it in the middle of July/2010, and I am almost 100% sure this site had a different set of classes listed in the "Package these jars in your WEB-INF/lib" section. I say it because my previous version worked well, but now, after upgrading to the following set, I am having a "java.lang.NoClassDefFoundError: org.apache.http.HttpRequest" very possibly due to some incompatibility.

       

      *  jboss-jsfunit-core-1.3.0.Final.jar
         * aspectjrt-1.2.1.jar
         * cactus-13-1.7.1.jar
         * junit-3.8.1.jar
         * nekohtml-1.9.14.jar
         * htmlunit-2.8.jar
         * htmlunit-core-js-2.8.jar
         * cssparser-0.9.5.jar
         * httpclient-4.0.1.jar
         * httpmime-4.0.1.jar
         * apache-mime4j-0.6.jar
         * commons-io-1.4.jar.jar
         * sac-1.3.jar
         * commons-lang-2.4.jar
         * commons-codec-1.4.jar
         * commons-logging-1.1.1.jar
         * commons-collections-3.2.1.jar
         * commons-httpclient-2.0.2.jar
         * cactus-ant-13-1.7.1.jar
         * cargo-0.5.jar
         * ant-1.5.4.jar

       

      Could somebody, please, give me any help or clue about this? Anyway, I would love also to have the previous set of libraries, but I could not find it in older versions of the "Document Wiki".

       

      Best regards,

      Euler Xavier de Oliveira.

          Hi Euler,

           

          Yes, the list of dependencies changed for JSFUnit 1.3.0.  This is because we upgraded to use HtmlUnit 2.8 and the dependencies for that changed.  I suspect that you still have an old version of HtmlUnit in your classpath somewhere.  The full stack trace should provide more clues if you want to post it.

            Dear Stan,

            here is my stack trace, I hope it will be helpful:

            I will also keep trying to find the error, but I would really appreciate if you could also send me the previous listing of libraries, if possible.

            Thank you very much.

              You are missing httpcore-4.0.1.jar.  I accedentally left it off the Getting Started page.  I'll fix that right now.

                ------------------------------------------------------------------------------------------------------------------------------------

                 

                The set of libraries is now complete, but remains (1)incompatible or (2)my system is somehow misconfigured. Just to remember, the previous listing of libraries worked well, and I am almost sure I didn't change any other relevant information in my project. That's why I think option (1) is more plausible.

                Do you have any idea for help me solving this, please? Thanks in advance!

                 

                Euler.

                  I notice you are using WebSphere.  Did you follow these special instructions?

                    I had read those instructions, but did not follow them, because I could run my test with no problems.

                    Here I can post my original source code, and you will see that I used FormAuthenticationStrategy successfully:

                      I think you must have JSFUnit 1.2 in your classpath somewhere.  I seem to remember an error like this when I was upgrading the code base to use HtmlUnit 2.8.

                        Stan,

                        I found out that the following set worked well for me:

                        htmlunit-core-js-2.7.jar
                        httpclient-4.0.1.jar

                        sac-1.3.jar

                         

                        I consider now that my first question has been answered. However, I am going to upgrade my Websphere Server from version 6.1 to 7.0. Some new questions are about to come.

                        Thanks for you attention!

                          In that case, you are definitely using JSFUnit 1.2 and not JSFUnit 1.3.  JSFUnit 1.3 won't work with HtmlUnit 2.7.

                            Stan,

                            I have noticed that, when I use JSFUnit 1.3, the failure related to the last stack trace I sent you (org.jboss.jsfunit.framework.FaceletsErrorPageException.isFaceletsErrorPage(FaceletsErrorPageException.java:55)), strangely only occurs if I try to connect over https but not when I connect over http! When I use JSFUnit 1.2, however, https works fine! Do you have any clue?

                            I see our scope is moving towards another subject, then I am going to start a new thread posting details about that, in case I consider useful for our community.

                             

                            Best regards,

                            Euler.
