          What exact SmartClient version is this? Your line numbers don't appear to line up with a release.

            #6
            SmartClient 70rc2

              Could you also post the logs from server startup - there may be something in there that will help.

                  OK, another step back. Are you including our Init servlet in your web.xml? (see http://www.smartclient.com/docs/7.0r...up..iscInstall)

                      The top exception is:
                      java.lang.NullPointerException
                      at com.isomorphic.datasource.DSRequest.parseUploadedFiles(DSRequest.java:336)

                      I decompiled the DSRequest and found the line 336 is:

                      int maxSize = config.getInt("DSRequest.maxUploadFileSize", 0);

                      so, it seems "config" is a null object, but when i access it from jsp, it worked:

                      <% Config cfg = Config.getGlobal(); %>
                      <%=cfg.getInt("DSRequest.maxUploadFileSize", 0)%>
                      the output is :104857600

                      really weird ! Can i get a copy of DSRequest.java file for debugging?

                        You can't debug this from DSRequest.java.

                        This error strongly suggests duplicate copies of the Isomorphic jars are in play. Do you perhaps have two or more copies, one on the system classpath, one on the classpath of Tomcat as a whole, one in web-inf/lib?

                          I didn't find duplicated isomorphic jars, this problem is so weird. How to resolve it, any idea? Maybe I need to upload files manually. what a pity!

                            After we changed the code in DSRequest:

                            from:
                            Code:
                            /* 336*/ int maxSize = config.getInt("DSRequest.maxUploadFileSize", 0);
/*1104*/ int maxSize = config.getInt("DSRequest.maxUploadFileSize", 0);
                            to:
                            Code:
                            /* 336*/ int maxSize = Config.getGlobal().getInt("DSRequest.maxUploadFileSize", 0);
/*1104*/ int maxSize = Config.getGlobal().getInt("DSRequest.maxUploadFileSize", 0);
                            it works!
                            So, the problem is why the config in DSRequest is null ? Is it caused by threading?

                            BTW, Could you guys change the DSRequest follow above snippet and give me class file?
