First of all, be sure the Tomcat server is OK for you. From your error log, we just see something wrong with your connection between Tomcat server and TAC.<BR />Best Regards<BR />Sabrina Thu, 11 Oct 2012 02:31:02 GMT Anonymous 2012-10-11T02:31:02Z https://community.qlik.com/t5/Talend-Studio/Project-Authorization-error/m-p/2240179#M27748 Hi I have created one user will all role and one project xyz.

For your issue, the Tomcat server has a little delay sometimes. You need re-start your TAC til the Tomcat server work well. Sorry for the inconvenience!<BR /><BR />Best Regards<BR />Sabrina Mon, 17 Sep 2012 04:43:58 GMT https://community.qlik.com/t5/Talend-Studio/Project-Authorization-error/m-p/2240180#M27749 Anonymous 2012-09-17T04:43:58Z https://community.qlik.com/t5/Talend-Studio/Project-Authorization-error/m-p/2240181#M27750 Hi Sabrina, <BR />I'm having the same issue. I have re-started TAC couple times, NO LUCK! <BR />I look into the log and it shows: <BR />ERROR TalendRemoteServiceServlet - Unexpected exception !!! <BR />java.lang.NullPointerException at org.talend.gwtadministrator.server.remoterepositorymgt.view.ProjectViewAdapter.hib2Gwt(ProjectViewAdapter.java:220) <BR />The Talend is v5.1.1. What else I can do? <BR />Regards, <BR />Simon Wed, 10 Oct 2012 18:32:12 GMT https://community.qlik.com/t5/Talend-Studio/Project-Authorization-error/m-p/2240181#M27750 SimonXu 2012-10-10T18:32:12Z https://community.qlik.com/t5/Talend-Studio/Project-Authorization-error/m-p/2240182#M27751 Hi, sxu<BR />Make sure some settings on the machine and network work well, and would you mind providing your issue screenshot to us?

It was caused by invalid data in table userprojectauthorization of Talend Administration DB. We believe the invalid data was generated by the Talend migration process. <BR />Thanks, <BR />Simon Fri, 12 Oct 2012 23:09:42 GMT https://community.qlik.com/t5/Talend-Studio/Project-Authorization-error/m-p/2240183#M27752 SimonXu 2012-10-12T23:09:42Z https://community.qlik.com/t5/Talend-Studio/Project-Authorization-error/m-p/2240184#M27753 Hi, sxu<BR />Thanks for your feedback, it is useful for us.<BR />Best Regards<BR />Sabrina Mon, 15 Oct 2012 11:04:14 GMT https://community.qlik.com/t5/Talend-Studio/Project-Authorization-error/m-p/2240184#M27753 Anonymous 2012-10-15T11:04:14Z
